Hi All
I am making a dialog based application using MFC.
I have written a function which is as follows:
Function(CString strPath)
{
CString strTempPath;
strTempath = strPath;
}
Now when i debug this function then as soon as control passes line "strTempath = strPath;"
It causes UNHANDELED EXCEPTION ERROR.
Why it is happening?
Please reply.
Thanks

Could you show me your actual coding and what actual value coming in strPath..
OT: try to follow nominal Variable naming convention while coding

Can you tell wots the exact error message. I feel your memory was already corrupted some time before it reached the Function(), but unfortunately its showing only from Function().

You better rebuild the application again.. It might help..

Hi!
I have a question about afx-message-handling in a MFC-Dialog (VS.NET 2003, WinXP).
I've got a main Dialog (CDialog) and a Child-Window in it (CStatic).
The goal is to handle afx-messages from the CStatic (ie. ON_WM_LBUTTONDOWN()) .
I did use the standard afx-message-map-mothod (ie. mapping ON_WM_LBUTTONDOWN() to afx_msg void OnLButtonDown(UINT nFlags, CPoint point)), but nothing happens.
Only the messages and handlers of the Main-Dialog are working.
I tried to put the focus on the Child-Window manually - no sucess. I tried to use CWnd instead of CStatic - no sucess.
Perhaps the CDialog messages are blocking the messages of the CStatic?!
Im really new in this and need a hint.
thanks in advance!

Include this style: SS_NOTIFY with the CStatic.
m_Static.ModifyStyle(0,SS_NOTIFY);
this is this.

Message boxes are Modal. You must dismiss them if you want to go back to the application.
The solution is to create your own "Custom Message Box", which is Modeless, created on-the-fly using Create(IDD_MY_BOX,this); Shown, using ShowWindow(SW_SHOW); etc.
Then you can click on the application window also while the message box is present.
I hope I understood your question.
this is this.

Hi, I'm working on having a CToolBar in my application, but with a difference. Instead of having the toolbar docked to a framewnd, I have the toolbar sitting inside a dialog of mine. The technique works just fine, and the toolbar behaves itself perfectly. However, the standard CToolBar seems to paint a "toolbar-background" underneath the CToolBarCtrl, which when you are not docking the toolbar inside a window is rather unsightly. Does anyone know how to make the background transparent?

have you seen call stack? because this is very general message.

Hello,
You probably did not initialize some of the MFC windows correctly. Try do step into the code and see the context of the error. From there you should be able to solve the problem, if not, please post more specific information!

I suppose that you have some window object (derived from CWnd) which is instantiated (created with new() operator or on stack), but not yet created (in Windows sense). for example, this can happen if you have some CEdit object in a dialog and you try to set its text limits inside the dialog constructor. CEdit object already exists, but edit window does not. therefore, the call will fail because it tries to send a message to the edit box, but it is not created yet. Right place for that would be inside OnInitialUpdate() override.

So have you looked at line 96 of afxwin2.inl to see what expression is evaluating to false?

hi, buddy
i use Crystal Report in my Vc++6.0 project, now i have a problem.
when creating a instance of IApplicationPtr using
try<br />
{<br />
m_pApplication.CreateInstance( __uuidof(Application) );<br />
}<br />
catch( _com_error& e )<br />
{<br />
HandleError( e );<br />
}
there is no exception, but m_pApplication is still NULL, what's wrong?

Dear fellow software engineers,
Im trying to link some example code from the MDSN website into my visual C++ project
and i get the following error. can you help?
Linking...
OLMECDlg.obj : error LNK2001: unresolved external symbol "int __cdecl
CheckTokenMembership(void *,void *,int *)"
(?CheckTokenMembership@@YAHPAX0PAH@Z)
Debug/OLMEC.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
the example code i was using was as follows:
#include
#include
extern BOOL CheckTokenMembership(HANDLE TokenHandle,PSID SidToCheck,PBOOL
IsMember);
/*++
Routine Description: This routine returns TRUE if the caller's process
is a member of the Administrators local group. Caller is NOT expected
to be impersonating anyone and is expected to be able to open its own
process and process token.
Arguments: None.
Return Value:
TRUE - Caller has Administrators local group.
FALSE - Caller does not have Administrators local group. --
*/
BOOL COLMECDlg::IsUserAdmin(VOID)
{
BOOL b;
SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
PSID AdministratorsGroup;
b = AllocateAndInitializeSid(
&NtAuthority,
2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0,
&AdministratorsGroup);
if(b)
{
if (!CheckTokenMembership( NULL, AdministratorsGroup, &b))
{
b = FALSE;
}
FreeSid(AdministratorsGroup);
}
return(b);
}
Please note that I have also setup my linker to include advapi32.lib but
this still fails. What am i doing wrong or is there a mistake on the MSDN
webpage?
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/s
ecurity/checktokenmembership.asp)
Has anyone used this function before,Can anyone help?
thanks,
Rainos

Or... The function is not a C++ decorated function, of which MOST of the Win32 API is not...
So, try this instead:
extern "C" {
extern BOOL CheckTokenMembership(HANDLE TokenHandle,PSID SidToCheck,PBOOL
IsMember);
}
Recompile and relink, see if that works for you
