I have a MFC CCheckListBox control working fine except Tab stops do not seem to work. When I supply the control with text strings that include the tab character ASCII 9 the text remains without any space for the Tabs.
Does anyone know if you can use tabstops in a CCheckListBox? I have tried a lot of different things and when I google I find same problem but no solutions. I have "Use Tabstops" box checked in the ListBox resource properties. I also have the Has Strings: True and Owner Draw: is Fixed (if that's any help). Here is the initialisation code that I am using:
BOOL CDlgQuotePOReceive::OnInitDialog()
{
CDialog::OnInitDialog();
VERIFY(((CCheckListBox *) this->GetDlgItem(IDC_LB_PO_DETAIL))->SetTabStops(10));
// Then code to fill the listbox with string data that
// is working fine to get the data into the control.
return TRUE;
}
The simple answer is no!
Reason: CCheckListBox ist just an owner draw list box. You can find the source code in the mfc. When the text is drawn the function just uses ExtTextOut and doesn't care about tab stops.
See implementation of CCheckListBox::DrawItem in VC\atlmfc\src\mfc\winctrl3.cpp
So the solution for you is also easy. Write your own class derived from CCheckedListBox and use your own DrawItem function. Also you have the source code of the current DrawItem function and you can easily use another text output function.

The whole day I am trying to solve this simple issue, but without any success.
I found a lot of hints in internet, but seems, that none of them is valid for my problem.
My issue is quite simple: I want to change the caption of a menue item while runtime
But it seems, that all solutions I found are very specific.
My requirements are this:
- it is a MFC application (VS2010)
- It is a SDI application, not MDI
- I want to change the caption of a main menu item (like "File"), not an entry of a submenue.
Because of main entry item, there is no ID for the menu item. Therefore solutions with ON_UPDATE_COMMAND_UI will not work!
My problems are:
- either the code I tried, is generating an assertion or exception
- or the function call returns with false
- or the function seems to work well, but I do not see any result (the caption is still unchanged)
Maybe I am using the wrong functions, or the wrong place for calling the functions.
Has anybody an example, which would work within my application pre-conditions?
Many, many thanks!

Windows cleverly hides the function to modify a menu under the arcane name of ModifyMenu. I hate it when they do things like that. Really makes me wish for Linux/Unix, with nice clear names like shmdt and mvwaddchnstr. Anyway, getting off my soap box for the moment, you'd call it something like this:
GetParentFrame()->GetMenu()->ModifyMenuW(1, MF_BYPOSITION, 0, L"New Item");
GetParentFrame()->Invalidate();
I have a rich text box that contains (a lot of) text. I've added a search option for it, and when the user presses the search button, the program marks all the matches in yellow (by performing selectionBackColor on each selection) and then selects the first match.
The result is that the program looks like it "scans" the text and then selects the first match.
I don't want this to happen so I need to disable the autoscrolling (that occurs when performing Select()) for a specific code segment.
I searched this problem before posting and the main topics I found involved appending text, and that's not my case.
Any idea of how to solve my problem?
I'm using .NET framework 4 (visual studio 2010) and I write in C#.
Thanks in advance,

Well it seems that I'll answer my own question - all I had to do was to put these two lines among with the other class's properties:
[DllImport("user32.dll", EntryPoint = "LockWindowUpdate", SetLastError = true, CharSet = CharSet.Auto)]
private static extern IntPtr LockWindow(IntPtr Handle);
and surround the desired code segment with this at the start:
LockWindow(this.Handle);
and this at the end:
LockWindow(IntPtr.Zero);
Our web application has some event code to "format" any text with pasted into a field so that any HTML styles do not break our data.
What would be a good way to pre-load the browser clipboard so that I can test pasting into the input field?
Is there any way to do it programmatic-ally or would I have the test script visit "a source page" and copy text before moving onto our application?
Any ideas or code snippets would be welcome.
Working with the clipboard will depend on your platform. E.g. on OS X, you can use pbcopy and Command-V:
open('|pbcopy', 'w') { |io| io << 'some text' }
browser.text_field(:name => 'q').send_keys([:command, 'v'])
I know there are equivalents on Linux (xclip?). Not sure about Windows.
I would consider using the .value= method to set the value. If it's been implemented the same as in watir, then it causes no events to be fired and sets the value directly, and then follow that up by sending an appropriate event (depending on what if any events are being monitored) such as onKeypress. I tried to figure out from the Watir-webdriver rdoc for textfield, if this distinction between .set and .value= has been maintained, but the way the doc describes them (at least there) makes them seem interchangable.. (Jarib can you clarify???)
Potentially you might need to first fire something like onFocus depending on the controls you are using. For example, as described in this SO case Setting a text field that has a JQuery mask on it for a jquery mask, they had to end up firing an unmask event to be able to even set the field.
This is a good case for utilizing the techniques described here How to find out which JavaScript events fired? and in the SO item linked in the comments for that question, to figure out just what events are fired when you manually paste something into a field. (note I would slueth it with both using the mouse, but also using something like tab to move between fields and set the focus, events common to those two methods are the ones most likely to be implemented by the controls.
I presume you have some kind of client side javascript that needs to check what was pasted into the field, and thus the reason for this test. If you are using standard HTML fields, with no javascript stuff, then I would consider this particular test case to be effectively the same as 'testing the browser' since supporting cut and paste in input fields is a standard browser function. In that case, you are sort of 'off the reservation' and I'd not bother with such a test case.
In my program I want the user to be able to choose between some options so I was using wxChoice component. Unfortunately after user interaction (clicking a button) I have to show custom text (not from my predefined list). Everything works fine if I use wxCombobox control but the drawback of this approach is that each time user selects an element from a list, selected text is highlited. It is annoying. I want the component to be read-only like. How to achieve this ?
Some code to visualize my question:
wxComboBox* viewAngle = wxDynamicCast( owner->FindWindow
( ID_CHOICE_3D_VIEWANGLE ), wxComboBox );
viewAngle->SetSelection( wxNOT_FOUND );
viewAngle->SetValue(_("Custom View"));
EDIT:
This control is used to set camera view in 3D object viewer application. Possible options are like: top, left, right, etc. It is also possible that the user moves 3D object using mouse. In that case I want my combobox to display "custom view" string. However "custom view" should not be a part of combobox list because selecting this option does nothing.
wxWidgets default implementation alwasy marks selected text. Which might be misleading for the user because he might think that he is expected to input any text.
IMHO, the custom text should be added to the wxComboBox control, the program could just ignore it when user selects that option.
Also, the wxComboBox's wxCB_READONLY style could be used to avoid the highlighting thing.
Hi
If any one knows how to use in-place warning message in MFC could you share info.
Is there a way to use it or is there any control we can use directly in mfc.
In-Place warning message: A warning message with appropriate icon along with warning message, will be displayed with in the same dialog.
I found some info about in-place message in msdn
InPlace message in msdn glossary
Different messages
Please share information.

From your comment, it appears that you're referring to this as an in-place message:
Ironically, of course, that's labeled as the incorrect example on the MSDN page that you link to. It's specifically recommended that you provide more specific advice, such as securing the projector with a password so that the presentation is not visible to unintended viewers. Putting that aside, however...
This is quite easy to implement in MFC. It's done simply with two STATIC controls, one on the left that displays an icon (in this case, a warning triangle) and the longer one on the right that displays static text (the warning message itself). If you're using the dialog editor to create your window, it's a simple matter of dragging the two controls to the dialog window and arranging them accordingly. There isn't a single control that encapsulates this functionality, but it's silly to expect that there would be, considering that doing it with two separate static controls is already so straightforward.
To load built-in icons such as the warning triangle shown above, you can use the LoadStandardIcon function and specify IDI_WARNING as the icon name. The complete list of values is available here. Obviously you can load any icon of your choosing as well; just add it to your project's resources.
Since you will presumably want to display the warning message only when it's applicable, you will need to programmatically hide and show the two controls depending on action taken by the user in your dialog. The standard ShowWindow member function makes this a trivial task. Call it on the two static controls, passing SW_SHOW as its argument if you want the warning message to be visible. Otherwise, you can specify SW_HIDE to hide the control.
As an alternative to what you are trying to do; you could place your message in a dialog:
int nResult = AfxMessageBox("Save changes to Current Job?", MB_YESNO);
if (nResult == IDYES)
{
OnFileSave();
}
