How to declare CFileDialog?
|
|
|
|
|
CFileDialog thinly wraps the windows file dialog control. Nearly every app I've seen uses it's
functionality or extends it.
It's got alot of settings, including how you give it a list of file types to browse for.
WELL documented!

Instead of finding other crazy solutions, why don't you simply debug your program ?
If you are stuck (after using your debugger to locate the problem), you can still post some relevant code here, with a detailed explanation, so that we can help you.

When i debug the application i got unhandled exception error msg
my code for browsing files is..
static TCHAR BASED_CODE szFilter[] = "Windows Setup file (*.exe; *.EXE; *.msi ;*.MSI)|*.exe ;*.EXE;*.msi;*.MSI||";
CFileDialog oFileDlg(TRUE,"exe","",OFN_FILEMUSTEXIST|OFN_NOCHANGEDIR, szFilter);
oFileDlg.m_ofn.lpstrTitle = "Select the Installable Application";
if(oFileDlg.DoModal() == IDOK)
{
m_strSetup = oFileDlg.GetPathName();
GetDlgItem(IDC_SETUP)->SetWindowText(m_strSetup);
}
Now can u help me

So, it has nothing to do with the File Dialog. Did you check with the debugger what was returned by GetDlgITem(IDC_SETUP) ? And also what was contained in m_strSetup ?
Chances are that you have a memory violation (that would be nice to explain what you get when you have an exception), probably because GetDlgItem(IDC_SETUP) returns NULL.

Does the IDC_SETUP control exist at this point? Step into the code using the debugger.

Are you sure IDC_SETUP is a valid control?

The "crash" doesn't mean you are using the wrong function, it just means you are using it incorrectly.

Hi,
AfxGetMainWnd()->SendMessage(WM_COMMAND, SetCursorPos(r.x,r.y))
The above code works fine
but
CPoint r;
AfxGetMainWnd()->SendMessage(WM_COMMAND, SetCaretPos(r));
doesn't work since SetCaretPos is a void function.
so how do I sendmessage for SetCaretPos(r)
Thanks

Those aren't messages they are APIs - part of Windows.
Call them directly anywhere:
SetCursorPos(r.x,r.y);
That's it.
Read up on the caret....it's a little more involved. There's only one caret for the system.

SetCaretPos and SetCursorPos are functions you dont need to use SendMessage

Hi,

I think you meant "fix the bugs" instead of "modify the bugs", right? 
Anyway, this is a longshot...
Are you trying to debug C++ ActiveX controls used in a VB6 project?
If so, in VC6, load up your ActiveX control project. Click on Project->Settings, click on the Debug tab. There's a field called "Executable for debug session:". Point it to your vb6.exe, and change the "Program Arguments" to your vb6 project. Then you should be able to debug your activex control (breakpoints, etc).
I think this used to work, it's been awhile.

Thanks.

Till the last day I belived that the global variables gets initialized automatically. But last day while debugging, I found out that the application start from the WinMainCRTStartup() function. And then stepping through that function, I came accross a function like this.
<br />
_initterm( __xc_a, __xc_z );
Then I understood that it is inside this function the global variables get initialized. That means the gloabl variable are explicity been initialized.
Can any one tell me whats this __xc_a and __xc_z variables are? And how the _initterm is doing the initialization?

It looks like __xc_a and __xc_z are arrays of function pointers - pointing to initialization
functions.
_initterm() loops through calling each function in __xc_a ... ?
It's in the runtime source code - see
crt0dat.c for _initterm()
cinitexe.c for __xc_a and __xc_z
crtexe.c for the xxxCRTStartup functions
