It is a bad design to assume that the dialog box owns the list control. Instead, send the message to the dialog and let it route it on to the control as it sees fit. This way the control can be changed without the calling routine needing to know the details.

first map the function click of the menu with its IDC no and in its function write the following code :
CFileDialog fileDlg (FALSE, "txt", "*.txt",
0, ".txt", this);
fileDlg.DoModal();
see mdn for the explanation on the parameters

Hi,
After changing alot of code in my MFC application, it is no longer
opens up. Compile has no errors or warnings. It seems that the program
DOES load, but exit immediatly.
Any idea where to look for? Any idea where i can put a break point to
help me catch it? How to define an entry point?

If you have a dialog based app you could look into the InitInstance method and add a breakpoint where you call the DoModal method. If the problem is inside the dialog class then begin looking into OnInitDialog method.
Hope it helps,

I've put a breakpoint in that function.
Does not reach there.... debuger did not stop there.
|
|
|
|
|
Does it reach the constructor of the app?

press F10
u will go to
extern "C" int WINAPI
_tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPTSTR lpCmdLine, int nCmdShow)
{
// call shared/exported WinMain
return AfxWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
}
no press F10 again and then F11 to go to the defination of afxwinmain
check out the afxwinmain function in "Winmain.cpp" by pressing "F10"
find out from which function call the program exit
int AFXAPI AfxWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPTSTR lpCmdLine, int nCmdShow)

No help.
Pressing f10 or f11 does not reach anywhere.
Again, it seems it starts (the layout of the VS changes) and it immediattly returns with return number 0xff.

Found my error. A simple bug in some other lib i used. But, i could find it after i added breakpoints to ALL the functions used in the solution.
Is there any simple way to debug an application from the first instruction?

Adding a breakpoint at the declaration of the global app object?

Try importing the ICO file into the 'Resource' view in the visual c++ program.
Make sure you remove the MFC default icon from that 'Resource' view.

Hi,
usually I replace the .ico file in the project's \res folder.

Hi there!
I am using CxImage library to display images in different formats in a Picture Control(VC++).It works fine with other file formats but as soon as some TIF Image format comes it generates the following two error messages in a message box.
IT DISPLAYS THE IMAGE FINE IN PICTURE CONTROL but I DON'T WANT TO GET THOSE ERROR MESSAGES.
The error messages are as follows:
1)TIFF IMAGE:wrong data type 1 for "XML Packet";tag ignored
2)TIFF IMAGE:unkown field with tag 34665(0x8769) encountered
The piece of code at which these error messages in message box prompted is as under:
HBITMAP m_bitmap = NULL;
unsigned long fileFormat;
if(getFileExtension() == ".tif")
{
fileFormat = CXIMAGE_FORMAT_TIF;
}//End of if(getFileExtension() == ".tif")
else if(getFileExtension() == ".gif")
{
fileFormat = CXIMAGE_FORMAT_GIF;
}//End of else if(getFileExtension() == ".gif")
else if(getFileExtension()==".jpg")
{
fileFormat = CXIMAGE_FORMAT_JPG;
}//End of else if(getFileExtension()==".jpg")
//CxImage imageFile(fileToDisplay, CXIMAGE_FORMAT_JPG);
MessageBox("File Clicked = "+ fileToDisplay);
CxImage imageFile(fileToDisplay, fileFormat);
m_bitmap = imageFile.MakeBitmap(m_PicToDisplay.GetDC()->m_hDC);
m_PicToDisplay.SetBitmap(m_bitmap);
if (m_bitmap) DeleteObject(m_bitmap);

This is driving me crazy. My application is a MFC Dialog Based Window. I have a button that brings up another modeless Dialog Box with some other buttons and information. I cannot move the second Dialog completely out of the way of my first one, so I would like to be able to Click on the Frame of the first Dialog Box and have it appear on top of the Second one. I have tried a lot of different calls to no avail. Here are some or all of them. Can anyone help please.
void CSCSInfoDlg::OnLButtonUp(UINT nFlags, CPoint point)
{
CDialog::OnLButtonUp(nFlags, point);
SetWindowPos(&this->wndTop , 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
BringWindowToTop();
Invalidate();
UpdateWindow();
SendMessage(WS_MAXIMIZE, 0, 0);
if (m_pParseLog) // second window
m_pParseLog->SetWindowPos(&wndBottom, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
// ShowOwnedPopups(false);
SetFocus();
}
