deriving Dialogs from a custom Dialog using mfc - visual-c++

I am trying to define a custom Dialog Template with certain members such as m_hImage, m_hName, and the m_hIcon in it. I want to then derive Dialogs using this Template.
I am not using any buttons(Ok,cancel etc.) in this template. Do i still need to declare or define OnOk(), OnCancel() etc.
Can anybody tell me what are the other methods I need to declare in this template class?
My goal is to just prepare this template dialog so that each dialog derived from this template contains a icon on the title bar (m_hIcon) , the image (m_hImage) on the upper left corner, and the image name (m_hName) on the upper right corner of dialog.

No, you need not to override any of the methods. You may however need to override OnInitDialog, otherwise you won't have any dialog initialization. This is the overridden method where you can setup the icon for dialog.

Create a generic popup panel

I have added a Global Button with the following code.
public override void Initialize()
{
if (!String.IsNullOrEmpty(Base.PrimaryView))
{
Type primaryViewItemType = Base.Views[Base.PrimaryView].Cache.GetItemType();
PXAction action = PXNamedAction.AddAction(Base, primaryViewItemType, "SubmitTicket", "Submit Ticket", TestClick);
}
}
public IEnumerable TestClick(PXAdapter adapter)
{
throw new PXException("Button clicked from graph" + Base.GetType().Name);
}
And it renders the button like this in each of the pages.
Now, I would like to display a popup panel, on button's click. I know I can create a popup panel on screen section. But, is there some way that I can have a general popup panel created in one place and can be displayed on each of the pages on the button's click?
Thank you.
As #HB_ACUMATICA mentioned there is no good easy way.
Providing another alternative to his post, you can create a graph and use it as a reusable popup by calling:
throw new PXPopupRedirectException(graph, string.Empty, true)
One thing I ran into was a sizing issue on the popup...
Changing the height/width when calling another graph as an in-page popup using PXPopupRedirectException
If you do copy and paste the PXSmartPanel you can create re-usable business logic by implementing the reusable business logic pattern found in this help as a starting point:
Reusing Business Logic
If I understand correctly you want to share the same PXSmartPanel control in different pages without having to copy/paste it in every screen.
In Acumatica Framework this is achieve by custom container controls like 'PXUploadDialog' which derives functionality from other controls like 'PXSmartPanel'. This is the control that is used when you attach files in all screen.
Unfortunately there seems to be no documentation on how to achieve this.
The closest I found is this SO question which is essentially unanswered:
Create custom User Control for Acumatica
Considering this, you may want to copy/paste the same smart panel in all screen.
To ease copying you can use the 'Edit ASPX' feature, make sure you backup the project before.
Edit ASPX to get to the code:
Copy paste your smart panel in the page and click 'GENERATE CUSTOMIZATION SCRIPT' to package the changes in the project:

Create and Load Custom Controls into FormView

i have a Form View in MFC. I try to include a dynamic Field, like C# User Control, where i can include other Controls, based on the clicked Item in the Lists.
I already found a User Control in Toolbox.
My question is:
Is it possible to create Form Views in Ressource View and add it to my Form View dynamically?
Can I use the Custom User Control to Replace it with my created FormView?
My FormView looks like this: Imagelink (Green Box should be filled with selected Control).
It is embedded in a TabView Item.
Or if this didnt work, i would bind different FormViews (Create same FormView with different green controls) to that TabView without the Ressource View at Runtime, is that possible?
I'm new to MFC and created my Prototype in C# .NET, so this is very hard to understand :)
I've found the solution. I'm now using different Groupboxes to arrange the Controls. I can show and hide them. Only the positioning should be a little bit hard.

Design Approach for Custom Control in C#

Am Creating a user control which will have a button, textbox and label. And i have created some delegates for Button and Textbox.
Now, i need some properties like assign text, visibility and some
other at runtime. For this whether shall i creating a Button itself
as property (or) creating each property for text and visibility. Which one is a good approach ?
I have created some custom events for Button. Now i have to avoid
the default events which is like OnClick e.t.c. Is it possible ?

Can I create a custom DialogPreference based on a pre-existing custom Dialog?

In my Android project I've already created a custom dialog: A class named SelectColorDialog, extending Dialog, that allows the user to view a large matrix of color cells in order to select a particular color. The dialog returns the selected color value (as Integer) to the dialog initiator – typically an Activity – via a callback function.
I've a similar custom dialog, SelectTypefaceDialog, to allow easy font selection. A list of available typefaces are shown, as ListView rows, each identified by name and with an associated short sample text rendered in that typeface. The available typefaces include usual droid fonts, such as NORMAL, MONOSPACE, etc. as well as any externally sourced TTF font files that the user cares to load into a particular subdirectory on the SDCard.
These custom dialogs were not initially designed to be used directly in conjunction with SharedPreferences, preferences definition XML files or with any PreferenceActivity. Instead of, each dialog can be popped up from any activity, via the user pressing a button or via a menu item. The activity classes that create these dialogs also have internal callback classes, selection event listeners, to detect when the user selects a color or font.
These two dialogs do not have OK and Cancel buttons. Instead, the user just clicks on an item - a view of some kind - in the dialog to select the corresponding color or typeface value (implicit OK) or else presses the device’s back button to dismiss the dialog with no action taken (implicit Cancel).
I would now like to go further and incorporate these two custom dialogs into the shared preferences framework via a preferences.XML and an associated PreferenceActivity.
I would prefer to base two DialogPreference subclasses directly on these existing dialogs if possible, but I cannot see how to do so. I suspect that I cannot, and that I'll need to start all over again, and copy or adapt all the java code that is presently in the custom dialog classes – for color or font display and selection – directly into the custom DialogPreference classes instead, perhaps by overriding onCreateDialogView() and/or other methods?
This question may be a bit old, but I hope to help those, looking at the same problem in future: just extend Preference instead of DialogPreference. DialogPreference is designed badly and expected "official" way to use custom Dialog - overriding protected showDialog method does not work, because this single method contains half of class logic.

Manually create a dialog child window using an ID from resource.h

I want to add a simple panel to a dialog created using Visual Studio resource editor, but the resource editor doesn't allow this - I need to add my own CWnd as a dialog child. However that way I think I have to use CWnd::Create manually, and pass in names for the class and the window.
I want to create an ID like IDC_MYPANEL, and as much as possible add the window so it works like something defined in the template. What's the right way to do this, and what's the best MFC class to use as a simple panel... just use CWnd itself?
What do you mean by 'a simple panel'? If it's a custom control, derive from CWnd, override Create() and call CWnd::Create() with NULL as the class name so that MFC makes its own, and add a line to resource.h with the IDC_XXX value of your control. If it's a sub-dialog, with controls on it, derive from CDialog and call CDialog::Create() with the IDD that you define in your dialog.
The only difference when creating a control at runtime is that in OnInitDialog, you do some Create() and initialisation things, and you don't include a DDX_Control() line for that control. For the rest everything works the same.
