Basically I've created a mfc dialog with a button saying load. I just want to do what it says on the tin. If anyone could help I'd be grateful. I'm guessing it's something to do with the CFile function.
Put this inside your load button clicked event.
CFileDialog l_fDlg(TRUE,NULL,NULL,OFN_OVERWRITEPROMPT,"Text Files (*.txt)|*.txt|Comma Separated Values(*.csv)|*.csv||");
int iRet = l_fDlg.DoModal();
CString l_strFileName;
l_strFileName = l_fDlg.GetPathName();
if(iRet == IDOK) {
try
{
CStdioFile file(_T(l_strFileName), CFile::modeRead);
CString str,contentstr = _T("");
while(file.ReadString(str))
{
contentstr += str;
contentstr += _T("\n");
}
}
catch(CException* e)
{
MessageBox(_T("Error"));
e->Delete();
}
}
According to your comment at hyperflow's answer:
CFileDialog is your friend. It's very easy to use.

I have come up with the following function which works as it should:
bool CChristianLifeMinistryStudentMaterialDlg::EncodeText(HWND hWnd, CString strCode)
{
bool bHandled = false;
map<HWND, CComboBox*> mapControls;
map<HWND, CString*> mapControlsText;
mapControls.emplace(m_cbMaterialAssignment1.GetSafeHwnd(), &m_cbMaterialAssignment1);
mapControls.emplace(m_cbMaterialAssignment2.GetSafeHwnd(), &m_cbMaterialAssignment2);
mapControls.emplace(m_cbMaterialAssignment3.GetSafeHwnd(), &m_cbMaterialAssignment3);
mapControls.emplace(m_cbMaterialAssignment4.GetSafeHwnd(), &m_cbMaterialAssignment4);
mapControlsText.emplace(m_cbMaterialAssignment1.GetSafeHwnd(), &m_strMaterialAssignment1);
mapControlsText.emplace(m_cbMaterialAssignment2.GetSafeHwnd(), &m_strMaterialAssignment2);
mapControlsText.emplace(m_cbMaterialAssignment3.GetSafeHwnd(), &m_strMaterialAssignment3);
mapControlsText.emplace(m_cbMaterialAssignment4.GetSafeHwnd(), &m_strMaterialAssignment4);
if (mapControls.find(::GetParent(hWnd)) != mapControls.end())
{
UpdateData(TRUE);
DWORD dwSel = mapControls[::GetParent(hWnd)]->GetEditSel();
CMeetingScheduleAssistantApp::EncodeText(*mapControlsText[::GetParent(hWnd)],
strCode, LOWORD(dwSel), HIWORD(dwSel));
UpdateData(FALSE);
bHandled = true;
}
else
{
map<HWND, CEdit*> mapControls;
map<HWND, CString*> mapControlsText;
mapControls.emplace(m_editBibleReading.GetSafeHwnd(), &m_editBibleReading);
mapControls.emplace(m_editDiscussionVideoTheme.GetSafeHwnd(), &m_editDiscussionVideoTheme);
mapControls.emplace(m_editDiscussionVideoMaterial.GetSafeHwnd(), &m_editDiscussionVideoMaterial);
mapControlsText.emplace(m_editBibleReading.GetSafeHwnd(), &m_strBibleReading);
mapControlsText.emplace(m_editDiscussionVideoTheme.GetSafeHwnd(), &m_strDiscussionVideoTheme);
mapControlsText.emplace(m_editDiscussionVideoMaterial.GetSafeHwnd(), &m_strDiscussionVideoMaterial);
if (mapControls.find(hWnd) != mapControls.end())
{
UpdateData(TRUE);
DWORD dwSel = mapControls[hWnd]->GetSel();
CMeetingScheduleAssistantApp::EncodeText(*mapControlsText[hWnd],
strCode, LOWORD(dwSel), HIWORD(dwSel));
UpdateData(FALSE);
bHandled = true;
}
}
return bHandled;
}
The code is straight forward to follow. But as you can see I have to potentially deal with either a comb box edit control or regular edit control. As a result, I have two sets of similar code.
Is it possible to consolidate some of this code without overcomplicating it too much? My project is set to the ISO C++ 17 Standard if that helps.
Update
Initially I thought I would try a single map of CWnd* pointers. But then I had the two problems of CComboBox verses CEdit.
CComboBox uses:
::GetParent(hWnd)
GetEditSel()
CEdit uses:
hWnd
GetSel()
By using a single list of CWnd* I no longer know which is a combo or a edit control.
—-
Update
The core problem I would like to solve is to have a single loop rather than the two.
One possibility would be to define an interface to the functionality you need, then a couple of implementations of that functionality. Add in a map to get from an HWND to the object you need, and you're off to the races:
class Writer {
virtual DWORD getSel() = 0;
CString* data;
public:
Writer(CString *data) : data(data) {}
void write(CString text) {
UpdateData(true);
DWORD selection = getSel();
CMeetingScheduleAssistantApp::EncodeText(*data, text, LOWORD(dwSel), HIWORD(dwSel));
UpdateData(false);
}
virtual ~Writer() = default;
};
class ComboBoxWriter : public writer {
CWnd *parent;
DWORD getSel() override { return parent->GetEditSel(); }
public:
ComboBoxWriter(CComboBox &dest, CString &data) : Writer(&data), parent(dest.GetParent()) {}
};
class EditCtrlWriter : public Writer {
CEdit *ctrl;
DWORD getSel() override { return ctrl->GetSel(); }
public:
EditCtrlWriter(CEdit &ctrl, CString &data) : Writer(&data), ctrl(&ctrl) {}
};
bool CChristianLifeMinistryStudentMaterialDlg::EncodeText(HWND hWnd, CString strCode) {
static std::map<HWND, Writer*> controls {
{ m_cbMaterialAssignment1.GetSafeHwnd(), new ComboBoxWriter(&m_cbMaterialAssignment1, &m_strMaterialAssignment1) },
{ m_cbMaterialAssignment2.GetSafeHwnd(), new ComboBoxWriter(&m_cbMaterialAssignment2, &m_strMaterialAssignment2) },
{ m_cbMaterialAssignment3.GetSafeHwnd(), new ComboBoxWriter(&m_cbMaterialAssignment3, &m_strMaterialAssignment3) },
{ m_cbMaterialAssignment4.GetSafeHwnd(), new ComboBoxWriter(&m_cbMaterialAssignment4, &m_strMaterialAssignment4) },
{ m_editBibleReading.GetSafeHwnd(), new EditCtrlWriter(&m_editBibleReading, &m_strBibleReading) },
{ m_editDiscussionVideoTheme.GetSafeHwnd(), new EditCtrlWriter(&m_editDiscussionVideoTheme, &m_strDiscussionVideoTheme) },
{ m_editDiscussionVideoMaterial.GetSafeHwnd(), new EditCtrlWriter(&m_editDiscussionVideoMaterial, &m_strDiscussionVideoMaterial) }
};
auto ctrl = controls.find(hwnd);
if (ctrl == controls.end())
return false;
ctrl->second->write(strCode);
return true;
}
This isn't a lot shorter overall (in fact, it's almost the same length), but quite a bit more of that length is boilerplate that's pretty easy to ignore.
Your building maps of HWND to MFC controls looks very strange.
Surely MFC already has that map. See if this helps: https://learn.microsoft.com/en-us/cpp/mfc/accessing-run-time-class-information?view=msvc-160
Based on the comments to one of the answers (#vlad-feinstein):
all HWND handles are unique system-wide
I decided that I could take a much simpler approach to simplifying my code:
bool CChristianLifeMinistryStudentMaterialDlg::EncodeText(HWND hWnd, CString strCode)
{
map<HWND, CWnd*> mapControls; // Use generic CWnd pointers
map<HWND, CString*> mapControlsText;
// Lookup map of controls
mapControls.emplace(m_cbMaterialAssignment1.GetSafeHwnd(), &m_cbMaterialAssignment1);
mapControls.emplace(m_cbMaterialAssignment2.GetSafeHwnd(), &m_cbMaterialAssignment2);
mapControls.emplace(m_cbMaterialAssignment3.GetSafeHwnd(), &m_cbMaterialAssignment3);
mapControls.emplace(m_cbMaterialAssignment4.GetSafeHwnd(), &m_cbMaterialAssignment4);
mapControls.emplace(m_editBibleReading.GetSafeHwnd(), &m_editBibleReading);
mapControls.emplace(m_editDiscussionVideoTheme.GetSafeHwnd(), &m_editDiscussionVideoTheme);
mapControls.emplace(m_editDiscussionVideoMaterial.GetSafeHwnd(), &m_editDiscussionVideoMaterial);
// Lookup map of text values
mapControlsText.emplace(m_cbMaterialAssignment1.GetSafeHwnd(), &m_strMaterialAssignment1);
mapControlsText.emplace(m_cbMaterialAssignment2.GetSafeHwnd(), &m_strMaterialAssignment2);
mapControlsText.emplace(m_cbMaterialAssignment3.GetSafeHwnd(), &m_strMaterialAssignment3);
mapControlsText.emplace(m_cbMaterialAssignment4.GetSafeHwnd(), &m_strMaterialAssignment4);
mapControlsText.emplace(m_editBibleReading.GetSafeHwnd(), &m_strBibleReading);
mapControlsText.emplace(m_editDiscussionVideoTheme.GetSafeHwnd(), &m_strDiscussionVideoTheme);
mapControlsText.emplace(m_editDiscussionVideoMaterial.GetSafeHwnd(), &m_strDiscussionVideoMaterial);
// Determine if the use clicked on a combo or edit control
bool bIsComboControl = false;
HWND hWndToUse = nullptr;
if (mapControls.find(::GetParent(hWnd)) != mapControls.end())
{
bIsComboControl = true;
hWndToUse = ::GetParent(hWnd);
}
else if (mapControls.find(hWnd) != mapControls.end())
hWndToUse = hWnd;
if (hWndToUse == nullptr)
return false;
// Process
UpdateData(TRUE);
// Get the correct selection from the control
DWORD dwSel = (bIsComboControl) ?
((CComboBox*)mapControls[hWndToUse])->GetEditSel() :
((CEdit*)mapControls[hWndToUse])->GetSel();
// Encode the text
CMeetingScheduleAssistantApp::EncodeText(*mapControlsText[hWndToUse],
strCode, LOWORD(dwSel), HIWORD(dwSel));
UpdateData(FALSE);
return true;
}
I was creating vs++ code using MFC framework .I have a Cedit Box named "IDC_EDIT1" in the form.Can anybody tell me how to check if the edit box is empty or not?
CEdit *editBox = (CEdit *) GetDlgItem(IDC_EDIT1);
if(editBox == NULL)
return;
CString str;
editBox->GetWindowTextW(str);
if(str.IsEmpty())
{
}
You can use the WM_GETTEXTLENGTH message:
int length = SendMessage(hwnd,WM_GETTEXTLENGTH,0,0);
if(length == 0)
{
MessageBox(0,"The edit box is empty.",0,0);
}
it's a calculator programme and I was checking on button press whether edit box control is empty or not.
The IDC_Display(Edit control) is connected to variable m_Display(cEdit Type)
I took another variable cString Type (m_TrialString). declare this on class definition just below m_Display.
on Button click event you write:
void CNewCalculatorDlg::OnBnClickedButton1()
{
m_Display.GetWindowText(m_TrialString);
if (m_TrialString.IsEmpty())
AfxMessageBox(_T("The CString is EMPTY"),MB_OK);
else
AfxMessageBox(_T("The CString is NOT EMPTY"), MB_OK);
}
Using Visual studio 2010 and MFC Doc/View Applications I want my SDI application to start up completely hidden, and after sometime or with receiving some message from tray icon it shows the mainframe, view and so on. I change the line m_pMainWnd->ShowWindow(SW_NORMAL); to m_pMainWnd->ShowWindow(SW_HIDE); in BOOL CMyApp::InitInstance() but the main frame just flickers after executing the application and then goes hiiden what should I do inorder to avoid this problem and keep the showing capability of main frame when ever I want.
Here is the solution for SDI/MDI app: The new MFC (with VC2010) overrides the m_nCmdShow value with a setting stored in the system registry. To change this behaviour, simply override the LoadWindowPlacement virtual function in the application class.
BOOL CAdVisuoApp::LoadWindowPlacement(CRect& rectNormalPosition, int& nFflags, int& nShowCmd)
{
BOOL b = CWinAppEx::LoadWindowPlacement(rectNormalPosition, nFflags, nShowCmd);
nShowCmd = SW_HIDE;
return b;
}
Normally if you have VC2005 or earlier the following will do:
// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);
m_nCmdShow = SW_HIDE;
// Dispatch commands specified on the command line. Will return FALSE if
// app was launched with /RegServer, /Register, /Unregserver or /Unregister.
if (!ProcessShellCommand(cmdInfo))
return FALSE;
// The one and only window has been initialized, so show and update it
m_pMainWnd->ShowWindow( m_nCmdShow);
m_pMainWnd->UpdateWindow();
Note that m_nCmdShow should be set to SW_HIDE before ProcessShallCommand for the flicker not to occur.
It looks like there might be a bug in VC2010 though. Since I have done this before it intrigued me and tried a fresh VC2010 project but it was not working. I noticed the problem was deep in the following MFC function.
BOOL CFrameWnd::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle,
CWnd* pParentWnd, CCreateContext* pContext)
{
// only do this once
ASSERT_VALID_IDR(nIDResource);
ASSERT(m_nIDHelp == 0 || m_nIDHelp == nIDResource);
m_nIDHelp = nIDResource; // ID for help context (+HID_BASE_RESOURCE)
CString strFullString;
if (strFullString.LoadString(nIDResource))
AfxExtractSubString(m_strTitle, strFullString, 0); // first sub-string
VERIFY(AfxDeferRegisterClass(AFX_WNDFRAMEORVIEW_REG));
// attempt to create the window
LPCTSTR lpszClass = GetIconWndClass(dwDefaultStyle, nIDResource);
CString strTitle = m_strTitle;
if (!Create(lpszClass, strTitle, dwDefaultStyle, rectDefault,
pParentWnd, ATL_MAKEINTRESOURCE(nIDResource), 0L, pContext))
{
return FALSE; // will self destruct on failure normally
}
// save the default menu handle
ASSERT(m_hWnd != NULL);
m_hMenuDefault = m_dwMenuBarState == AFX_MBS_VISIBLE ? ::GetMenu(m_hWnd) : m_hMenu;
// load accelerator resource
LoadAccelTable(ATL_MAKEINTRESOURCE(nIDResource));
if (pContext == NULL) // send initial update
SendMessageToDescendants(WM_INITIALUPDATE, 0, 0, TRUE, TRUE);
return TRUE;
}
m_nCmdShow is still SW_HIDE when this function executes but it changes to SW_SHOWNORMAL when if (!Create(lpszClass... line executes. I don't know why this happens in VC2010 project only, sounds like a bug to me.
My sample project was SDI.
This comes from a dialog based application but you should be able to convert it to a Doc/View app as well. You need to handle the OnWindowPosChanging event. The key line is the the one inside the if statement. This allows my application to start completely hidden from view.
void CIPViewerDlg::OnWindowPosChanging( WINDOWPOS FAR* lpWindowPosition )
{
if( !m_bVisible )
{
lpWindowPosition->flags &= ~SWP_SHOWWINDOW;
}
CDialog::OnWindowPosChanging( lpWindowPosition );
}
Make sure that you are correctly turning off the WS_VISIBLE bit in CMainFrame::PreCreateWindow(CREATESTRUCT& cs). Something like this should worK:
cs.style &= ~WS_VISIBLE;
We had simply been negating the bit instead of turning it off, and we got away with it in VS 6.0 because this function was called only once. It is called twice in newer versions of Visual Studio, so in the second call we were flipping it right back on again. :-O
I tried all for Visual Studio 2010 and finished up with:
class CMainFrame : public CFrameWndEx
{
// ...
// Attributes
public:
BOOL m_bForceHidden;
// ...
// Overrides
public:
virtual void ActivateFrame(int nCmdShow = -1);
//...
};
CMainFrame::CMainFrame() : m_bForceHidden(TRUE)
{
// ...
}
void CMainFrame::ActivateFrame(int nCmdShow)
{
if(m_bForceHidden)
{
nCmdShow = SW_HIDE;
m_bForceHidden = FALSE;
}
CFrameWndEx::ActivateFrame(nCmdShow);
}
Other tricks did not work for me.
Found solution at:
http://forums.codeguru.com/showthread.php?478882-RESOLVED-Can-a-Doc-view-be-hidden-at-startup
I found in VS2017 (using BCGControlBar Pro which is what MFC Feature Pack was based on) that you have to handle things in two places:
BOOL CMainFrame::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle, CWnd* pParentWnd, CCreateContext* pContext)
{
if (!__super::LoadFrame(nIDResource, dwDefaultStyle, pParentWnd, pContext))
{
return FALSE;
}
// undo what __super::LoadFrame() does where it will set it to SW_NORMAL if not SW_MAXIMIZED
AfxGetApp()->m_nCmdShow = SW_HIDE;
}
BOOL CTheApp::LoadWindowPlacement(CRect& rectNormalPosition, int& nFflags, int& nShowCmd)
{
BOOL b = __super::LoadWindowPlacement(rectNormalPosition, nFflags, nShowCmd);
nShowCmd = SW_HIDE;
return b;
}
I have an url (e.g. http://localhost/Aanbod/Pagina.aspx) and I want to know the tab id, so I can make a friendly url with query (e.g. http://localhost/Aanbod/Pagina/QueryKey/QueryValue/).
Anyone has an idea?
Edit:
I'm not on the page itself. Want to know it from any page possible.
The url does not contain the tab id itself, so it can't be extracted.
if Pagina.aspx is a page in dotnet nuke like Home or Getting Started then you can find the tab id by
DotNetNuke.Entities.Tabs.TabController objTab = new DotNetNuke.Entities.Tabs.TabController();
DotNetNuke.Entities.Tabs.TabInfo objTabinfo = objTab.GetTabByName("Pagina", this.PortalId);
int Tabid = objTabinfo.TabID;
Well, this post is a little bit old, and I don't know if someone still looks for a solution. I had this problem recently and here is the pieces of code I wrote to solve it:
public int GetTabIDFromUrl(string url, int portalID)
{
int getTabIDFromUrl = 0;
// Try the "old" way with the TabID query string
if (url.ToLower().IndexOf("tabid") > 0)
{
Int32.TryParse(Regex.Match(url, "tabid[=/](\\d+)", RegexOptions.IgnoreCase).Groups[1].Value, out getTabIDFromUrl);
}
// When there is no result (because of advanced or human friendly or whatever Url provider)
if (getTabIDFromUrl == 0)
{
TabCollection tabs = TabController.Instance.GetTabsByPortal(portalID);
foreach (KeyValuePair<int, TabInfo> k in tabs)
{
TabInfo tab = k.Value;
if (tab.FullUrl.StartsWith(url))
{
getTabIDFromUrl = tab.TabID;
break;
}
}
}
return getTabIDFromUrl;
}
This could be a pain with sites that have a lot of pages, therefore it could be useful if you have some additional information to shrink the list that you have to loop through - e.g. a ModuleId of a module that is placed on this tab:
public int GetTabIDFromUrl(string url, int moduleID, int portalID)
{
int getTabIDFromUrl = 0;
// Try the "old" way with the TabID query string
if (url.ToLower().IndexOf("tabid") > 0)
{
Int32.TryParse(Regex.Match(url, "tabid[=/](\\d+)", RegexOptions.IgnoreCase).Groups[1].Value, out getTabIDFromUrl);
}
// When there is no result (because of advanced or human friendly or whatever Url provider)
if (getTabIDFromUrl == 0)
{
IList<ModuleInfo> modules = ModuleController.Instance.GetTabModulesByModule(moduleID);
foreach (ModuleInfo module in modules)
{
TabInfo tab = TabController.Instance.GetTab(module.TabID, portalID);
if (tab.FullUrl.StartsWith(url))
{
getTabIDFromUrl = tab.TabID;
break;
}
}
}
return getTabIDFromUrl;
}
Hope that helps someone...
Happy DNNing!

I hope this will solve your issue

Sorry, my bad!!
Here is your answer
http://www.dotnetnuke.com/Resources/Forums/forumid/118/threadid/89605/scope/posts.aspx :)
From a modal MFC dialog, I want to extract text from an edit box after the dialog is closed. I attempted this:
CPreparationDlg Dlg;
CString m_str;
m_pMainWnd = &Dlg;
Dlg.DoModal();
CWnd *pMyDialog=AfxGetMainWnd();
CWnd *pWnd=pMyDialog->GetDlgItem(IDC_EDIT1);
pWnd->SetWindowText("huha max");
return TRUE;
It does not work.
The dialog and its controls is not created until you call DoModal() and as already pointed, is destroyed already by the time DoModal() returns. Because of that you cannot call GetDlgItem() neither before, nor after DoModal(). The solution to pass or retrieve data to a control, is to use a variable in the class. You can set it when you create the class instance, before the call to DoModal(). In OnInitDialog() you put in the control the value of the variable. Then, when the window is destroyed, you get the value from the control and put it into the variable. Then you read the variable from the calling context.
Something like this (notice I typed it directly in the browser, so there might be errors):
class CMyDialog : CDialog
{
CString m_value;
public:
CString GetValue() const {return m_value;}
void SetValue(const CString& value) {m_value = value;}
virtual BOOL OnInitDialog();
virtual BOOL DestroyWindow( );
}
BOOL CMyDialog::OnInitDialog()
{
CDialog::OnInitDialog();
SetDlgItemText(IDC_EDIT1, m_value);
return TRUE;
}
BOOL CMyDialog::DestroyWindow()
{
GetDlgItemText(IDC_EDIT1, m_value);
return CDialog::DestroyWindow();
}
Then you can use it like this:
CMyDialog dlg;
dlg.SetValue("stackoverflow");
dlg.DoModal();
CString response = dlg.GetValue();
Open your dialog resource, right-click on the textbox and choose "Add variable", pick value-type and CString
In the dialog-class: before closing, call UpdateData(TRUE)
Outside the dialog:
CPreparationDlg dlg(AfxGetMainWnd());
dlg.m_myVariableName = "my Value";
dlg.DoModal();
// the new value is still in dlg.m_myVariableName
DoModal() destroys the dialog box before it returns and so the value is no longer available.
It's hard to tell why you are setting m_pMainWnd to your dialog. To be honest, I'm not really sure what you are trying to do there. That's bound to cause problems as now AfxGetMainWnd() is broken.
Either way, you can't get the dialog box's control values after the dialog has been destroyed.
I often use
D_SOHINH dsohinh = new D_SOHINH();
dsohinh.vd_kichthuoc=v_kichthuocDOC;
dsohinh.vd_sohinh=v_soluongDOC;
if(dsohinh.DoModal()==IDOK)
{
v_soluongDOC=dsohinh.vd_sohinh;
v_kichthuocDOC=dsohinh.vd_kichthuoc;
}
SetModifiedFlag(true);
UpdateAllViews(NULL);
With dsohinh is Dialog form that you want to get data to mainform .
After get data then call SetModifiedFlag(true) to set view data updated.
call UpdateAllViews(NULL) to Set data to mainform
This solution may seem long, meaning that so much code has been written for this seemingly small task.
But when we have a list or tree inside the child window where all the items are created in the child window
and the items have to be moved to the parent window,
then it makes sense.
This source code can easily create a window and transfer information from the window before closing to the parents.
//copy the two functions in your code
//1- bool peek_and_pump(void)
// template<class T,class THISCLASS>
//2- void TshowWindow(int id,T *&pVar,THISCLASS *ths)
//and make two member variable
// bool do_exit;
// bool do_cancel;
//in child dialog class.
//set true value in do_exit in child dialog for exit
CchildDialog *dlg;
template<class T,class THISCLASS>
