Thanks Elaine!
I think the ISDN (or whatever) support makes sense. I appreciate the help.

Hi, I have coded a custom CMiniDockFrameWnd derived class that removes the WS_CAPTION bit from its style to remove the title bar from the toolbar in the app.
Only trouble is that that CDockContext class calls a static function in CMiniFrameWnd to calculate the drag rect of the bar. The function is defined as;
<br />
static void PASCAL CalcBorders(LPRECT lpClientRect,<br />
DWORD dwStyle = WS_THICKFRAME | WS_CAPTION, DWORD dwExStyle = 0);<br />
<br />
void PASCAL CMiniFrameWnd::CalcBorders(<br />
LPRECT lpClientRect, DWORD dwStyle, DWORD dwExStyle)<br />
{<br />
UNUSED_ALWAYS(dwExStyle);<br />
<br />
AdjustWindowRectEx(lpClientRect, dwStyle, FALSE, WS_EX_PALETTEWINDOW);<br />
}<br />
Believe it or not, the CDockContext class uses the default parameters of the function so the drag rect of a tool bar is always calculated with a title bar and thickframe. This causes series bugs in my app not just a mis-aligned toolbar drag rect but the entire toolbar dragging screws up.
I was wondering if anyone knew a way to modify how CalcBorders behaives or how to modify the CDockContext::startDrag function without vast amounts of rewriting of MFC.

hello guys,
I am doin progamming in MFC for building a multi document interface. In that I am havin a openGL program which displays a bmp image. Can anyone help me how I can add that program to my MFC program in which I have defined a button for running the above bmp display program.
If anyone having problems in understanding plz let me know i'll try to clarify them.
thanks in advance,

You want to spawn the OpenGL application, correct? One solution is CreateProcess().

I am very thankful for your suggestion. The first and foremost thing that I have to do is to open a bmp image when I use the open option on my interface in a seperate document (I mean window), but I am not getting how to write a process for any menu item (and where to define that process in my MFC program) that I create on the interface and I am also having 'save' and 'save as' options and I think I have to define processes for them also....but I don't know how to define them. But i have gone through 'CBitmap' functions but I am not getting how to define them in my MFC program so that I can display any bmp image when I use my open option on my interface.

I have a program which pops a window on an event, an incoming phone call. This bit of code works.
HWND temphwnd;
temphwnd = FindWindow(NULL,ProgramTitle);
ShowWindow(temphwnd,SW_RESTORE);
and I can minimize it when the call drops by.
ShowWindow(temphwnd,SW_MINIMIZE);
Can anyone tell me how I can find out the current state of my program window so that I can leave it in the same state as when the call came in. If the user has the window up and active I dont want to minimize it when the call drops.

OK Thanks for that so far 
That gives me the Maximized/Minimized state in that it returns
SW_NORMAL if the window is maximized and SW_SHOWMINIMIZED if minimized. The next problem is, if the window is Maximized but behind another window how can I tell that and what call do I need to bring it to the front and make it active.
If I call ShowWindow(temphwnd,SW_RESTORE); that has no effect if the window is already Maximized but not active. The write up for SW_RESTORE says "Activates and displays the window" but this does not appear to work.

You may want to follow the ShowWindow() with a BringWindowToTop().

I have written a simple, no frills managed C++ DLL, and am having trouble referencing it in a seperate C# project. Specifically, the C# compiler gives me an error, asking whether I have neglected to add a reference or using statement pointing to my library/namespace. However, I cannot insert a using statement in my C# code, even after properly referencing it in my project (right-click on the References icon in the Solution Explorer, click on Add Reference...).
ILDASM can traverse the C++ library, and in it I find my method (I have just one), so I suspect there is nothing wrong in the manner it compiled.
Also, the DLL I'm wanting to reference is in the same directory (bin/) as my C# project's DLL.
Is there anything special I have to account for when writing managed C++, and want to include it in a project of a different language?

I'm getting an error when I try to inherit a new view class for a MDI application, and I can't figure out why :/ .. First I created an OpenGL viewport inherited from CView, and packed it with all kinds of functionality. It works great. But now I'm trying to derive a new view class from it, and I'm getting the following error (using VC++ 6.0 professional):
C:\DEVELOPMENT\MotionX\MotionX.cpp(119) : error C2039: 'classCMotionXModelView' : is not a member of 'CMotionXModelView' c:\development\motionx\motionxmodelview.h(15) : see declaration of 'CMotionXModelView'
C:\DEVELOPMENT\MotionX\MotionX.cpp(119) : error C2065: 'classCMotionXModelView' : undeclared identifier
The thing is, I'm just deriving it from a class that is fully functional, and haven't added anything except a member variable to it.
This is the view class declaration that works:

<br />
This is the derived class.
<br />
<br />
#if !defined(AFX_MOTIONXMODELVIEW_H__AEBACD4C_059E_4D0D_8F56_6A4EFD2C25E9__INCLUDED_)<br />
#define AFX_MOTIONXMODELVIEW_H__AEBACD4C_059E_4D0D_8F56_6A4EFD2C25E9__INCLUDED_<br />
<br />

#pragma once<br />
#endif // _MSC_VER > 1000<br />
<br />
#include "MotionXGLView.h"<br />
#include "MotionXModel.h"
<br />
class CMotionXModelView : public CMotionXGLView <br />
{<br />
public:<br />
CMotionXModel model;<br />
<br />
CMotionXModelView();<br />
virtual ~CMotionXModelView();<br />
<br />
};<br />
<br />
#endif // !defined(AFX_MOTIONXMODELVIEW_H__AEBACD4C_059E_4D0D_8F56_6A4EFD2C25E9__INCLUDED_)<br />
<br />
And this is my InitInstace code in my CMotionXApp class, that should tie the new class to the new document template:
<br />
m_pSceneTemplate = new CMultiDocTemplate(IDR_MOTIONTYPE,
RUNTIME_CLASS(CMotionXSceneDoc),
RUNTIME_CLASS(CChildFrame),<br />
RUNTIME_CLASS(CMotionXGLView) );
<br />
AddDocTemplate(m_pSceneTemplate);<br />
<br />
<br />
m_pModelTemplate = new CMultiDocTemplate(IDR_MOTIONTYPE,
RUNTIME_CLASS(CMotionXModelDoc),
RUNTIME_CLASS(CChildFrame),<br />
RUNTIME_CLASS(CMotionXModelView) );
<br />
Can anyone see what the problem is ??

Uncomment this in your derived class, and add IMPLEMENT_DYNCREATE(CMotionXModelView, CMotionXGLView) in your .cpp file

Hi there!
Is there a way to obtain the parent process' handle using Win32 APIs?
One obvious way is to pipe the handle obtained by GetCurrentProcess() to the child process. But, I wanted to know if there's a direct way.
Thanks for your help!
Regards,
Sachin

Have you see the PROCESSENTRY32 structure, specifically the th32ParentProcessID member?

Hello friends,
I had attend some interviews in recent time and faced one common question.
"When a database application can be developed using VB, then whats the advantage for using VC++ for that same application?"
Please tell me the advantage so that I can easily answer if the same question is asked
Thank you,

none.
except maybe if there's some sort of cross-platform compatibility needed on the front end.

There's multi-threading of course.
VC++ clients can be made more UI responsive esp. if talking about large recordsets. Clever usage can help alleviate the annoying UI stalls.
Conversely, VC++ is much more costly to develop than VB (generally)
Cheers,
Andy

If the person doing the developing is more fluent in VC++, it will probably result in less cost, and quicker turn-around time.
