He's asking about merging two apps, I'm asking about extending an app, which is very different.

Plus, I've no choice to make, we're on MFC and will be staying there. Just wondering if I can make use of the .net stuff that's out there within my MFC apps, or if I will need to stick to Windows API and MFC stuff only?

While you can use .NET controls in MFC apps in VC 2003, it's a lot more easier with VC 2005, because MFC has some new WinForms interaction classes.

Fantastic!

We're going to be evaluation '05 pretty soon... In the mean time, do you know of any web resources / articles here on CP about doing it in '03? I've had a look here and on MSDN, but didn't spot anything.

Yes it is possible to use Dundas' .Net controls in MFC. In fact there have been enough clients who do this Dundas' technical support has made MFC wrapper classes to make it even more straight forward.

i don't know why you're doing this, but even if it is possible, you're completely loosing the point with using and intermediate language such as MSIL...

.NET is supposed to be plateform independant ; MFC isn't...

make your choice...!

It's not possible to integrate 2 exes (unless you want to end up with 1 exe). Make one of them a DLL and call it from the other. You can use a .NET DLL from an MFC exe, and you can use an MFC extension DLL from .NET (provided the .NET app uses C++).

I believe you looking for Save Button.. pass that structure in GetSaveFileName(..) api

Ohh Sorry.. I Misunderstood your question! For that you have to subclass the File Open Dialog.. here are the article dealing with same :-

MDI child area with and without 3D border

icklePhil14-Dec-05 22:23

14-Dec-05 22:23

Hello!

I'm developping a MDI application in MS Visual C++ .NET (Managed C++ and GUI-Designer).
As my child windows are of dialog style (3D border and grey), I looked for a way to remove the inside 3D border of the MDI child area while the child windows are maximized and to put the border back on if they are normalized again.
All this because it doesn't look very nice when you maximize a 3D bordered window in another 3D bordered window (you get a "double border" then).
See these pictures illustrating what I mean:
Normal child window:
http://www.geocities.com/icklephilipp/ura_situation1.gif
Maximized child window with "double border":
http://www.geocities.com/icklephilipp/ura_situation2.gif
Maximized child window with merged border (this is what it should look like):
http://www.geocities.com/icklephilipp/ura_situation3.gif
I did manage to remove the 3D border with this code:
To remove the border:

System::Void MainForm::AddClientEdge(System::Windows::Forms::MdiClient* mdi)
{
	if (mdi != NULL) {
		// Get Styles using Win32 calls
		int style = GetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_STYLE);
		int exStyle = GetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_EXSTYLE);
		// Add borders on the Mdi.
		style &= ~WS_BORDER;
		exStyle |= WS_EX_CLIENTEDGE;
		// Set Styles using Win32 calls
		SetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_STYLE, style);
		SetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_EXSTYLE, exStyle);
		// SWP_FRAMECHANGED using Win32 call
		SetWindowPos((HWND)mdi->Handle.ToPointer(), (HWND)IntPtr::Zero.ToPointer(), 0, 0, 0, 0,
			SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOOWNERZORDER | SWP_FRAMECHANGED);
	}
}

To put the border back on:

System::Void MainForm::RemoveClientEdge(System::Windows::Forms::MdiClient* mdi)
{
	if (mdi != NULL) {
		// Get Styles using Win32 calls
		int style = GetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_STYLE);
		int exStyle = GetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_EXSTYLE);
		// Remove any borders on the Mdi.
		style &= ~WS_BORDER;
		exStyle &= ~WS_EX_CLIENTEDGE;
		// Set Styles using Win32 calls
		SetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_STYLE, style);
		SetWindowLong((HWND)mdi->Handle.ToPointer(), GWL_EXSTYLE, exStyle);
		// SWP_FRAMECHANGED using Win32 call
		SetWindowPos((HWND)mdi->Handle.ToPointer(), (HWND)IntPtr::Zero.ToPointer(), 0, 0, 0, 0,
			SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOOWNERZORDER | SWP_FRAMECHANGED);
	}
}

The big problem now occurring is shown in this picture:
http://www.geocities.com/icklephilipp/ura_strange.gif
The menubar of the main window changes like this if one switches between different child windows via the "Window" menu while the child windows are maximized.
Does anyone know, what relation these two functions have in particular?
I don't get it at all! Eek! | :eek:

I'm grateful for any ideas or thoughts!
