I am working on improving the memory consumption for one server application.
so for this I am looking the virtual memory consumption for a process.
Is there any API to get virtual memory for a process in VC++?

thanks

MDI child area with and without 3D border

icklePhil14-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!

Greets, icklePhil

Finally I solved the problem myself:
I needed to override the WndProc function of the child form and catch the WM_SYSCOMMAND message there. WM_SYSCOMMAND has in its wParam value one of the values SC_MAXIMIZE, SC_RESTORE, SC_MINIMIZE, or others. With this I can fire my own maximizing/minimizing/restoring events! These don't interfer with the child form switching.
Sample code:

// Override WndProc function to trap minimize, restore and maximize buttons
void WndProc(Message* m)
{
	if (m->Msg == WM_SYSCOMMAND) {
		switch (m->WParam.ToInt32()) {
			case SC_MAXIMIZE:
				ConnectionFormMaximizeEvent(this, new System::EventArgs());
				break;
			case SC_RESTORE:
				ConnectionFormRestoreEvent(this, new System::EventArgs());
				break;
			case SC_MINIMIZE:
				ConnectionFormMinimizeEvent(this, new System::EventArgs());
				break;
		}
	}
	else if (m->Msg == WM_NCLBUTTONDBLCLK) {
		ConnectionFormMaximizeEvent(this, new System::EventArgs());
	}
	__super::WndProc(m);
}

Note:
You will need some header file(s) from Win api that define(s) the WM_... and SC_... constants.
But I don't remember which one right now.

Bye, icklePhil

i don't know what's wrong, but the error is in disassembler.hpp, around line 24, so i don't understand why you gave the whole code of definition.h Frown | :(

Thanks for your reply.
I have included definitions.h in disassembler.hpp so that source of this error can be in definitions.h. In my past experiences precompiler directives can be source of errors like this. Especially included files. Some times I had extra ';' token at the end of a header file and I got errors similar to this error in file that included the header file.
I thought that maybe I have error in definitions.h.

I gonna be crazy. What the heck is this error ?!? It's so simple statement.

You could run the code through the preprocessor (only) and examine the output.
That's one way...

Use the compiler options

/E (Preprocess to stdout)
Or better still:
/P (Preprocess to a file)

I think you are getting these error messages because you are including a C++ header file and a class in a .C file. The file which is including the .HPP file must be a .CPP file.

this is this.
