what do you really want to do?
I think you can use SetWidnowsLong to replace its original processing function then you can get the first chance to deal with key message.
And for SendMessage and PostMessage, you can just hook the two API function as normal.

Hello Everyone,
Can anyone please suggest me some tutorials and notes for connecting VC++ 8 with MySql ??
I have 2 pc’s here in one pc I have MySql installed & it’s a sever ,... for using MySql in my PC is it required to install SQL in my PC also ? or I can access the tables directly without installing MySql in my PC ?
I am very much new to both the things …so asking very silly Questions. 
Thanking you,
Naveen HS

No you dont need to install MySql server in your PC. I will recommend using MySql++[^].

CWnd cw;

Your code declares objmyActivX and cw and then tries to use them before either of them has been initialised to a value.
|
|
|
|
|
the objmyActivX will be initialize with calling Create function.
do i initialize with what value the cw?

Not true I'm afraid. You are trying to invoke the Create() method on the objmyActivX object, which has no value. It would appear that you need to spend some time understanding C++ and whatever functionality you are trying to use here.
zon_cpp wrote: do i initialize with what value the cw?
I presume from its declaration this is some window belonging to the application but I don't really understand how this fits in to what you are attempting.

What's wrong with my code to load an image from a file? It doesn't seem to work. Or is it the code to make it into an HDC that causes the problem?
HBITMAP LoadBitmapFromFile(LPCTSTR szFilename)
{
HBITMAP hBitmap = NULL;
hBitmap = (HBITMAP)LoadImage(NULL, szFilename, IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE);
return hBitmap;
}
HDC userNewHDC;
HBITMAP userNewBitmap;
userNewBitmap = LoadBitmapFromFile("C:\imagefile.bmp");
userNewHDC = CreateCompatibleDC(NULL);
SelectObject(userNewHDC,userNewBitmap);
I then BitBlt the userNewHDC object but it doesn't seem to work. Whats wrong?

You should check the return values and the error codes using GetLastError().
|
|
|
|
|
Try using the Debugger to see if LoadBitmapFromFile returns NULL or a valid handle.
You can than use GetLastError() to see what went wrong.
Looking at your code I would say you should change:
userNewBitmap = LoadBitmapFromFile("C:\imagefile.bmp")
to:
userNewBitmap = LoadBitmapFromFile("C:\\imagefile.bmp");

Hi,
I utilize Visual C++ 2003 and MFC with document/view architecture..
I want to respond differently when I choose Print from the menu and the Print button from the toolbar. The reason is that I want to select the file to print when I choose from the menu, and I want to print directly the open file when I choose from the Print toolbar button.
How can I do that ?
Thanks,
Claude

Connect them to different triggers.

I want to draw menu without the shadow frame, but i don't know how to deal with the frame of the menu. I searched but only found one project Professional User Interface Suite[^] implemented this. But, the project is so huge, so, i almost can't find how it reaches its aim.
Any ideas will be very appreciated.
