Probably, you are writting out of bounds for this array. Can you show, how you are using this array ?

When I close the File Selection Dialog by selecting cancel button or when selecting file and click ok button, the application is closing without any message. Previously I had the same problem because of Adobe Acrobat Reader and resolved after uninstalling Adobe reader. But now there is problem even I dont have Adobe reader and uninstalled Foxit reader.
No problem in other systems.
I cannot see problem in Debug mode.

Does this question relevant to c++? or its another question

|

I want to find the cause using VC++ debugger.
Before I found some dlls of Adobe Reader was running while File Dialog was open in Call stack window. This time problem is only in release mode.

I too had that pblm in the file selection dialog after setting the _WIN32_WINNT=0x501. But I found that the pblm is not coming if the CFileDialog is created in heap instead of stack.

How can we decide creating dialog in heap or stack?

I though the problem is in your program. But if it is in third party applications, whats the use even if you found out its in stack or heap?
If the problem is in your application, change the creation of CFileDialog stack to heap as follows
CFileDialog *pDlg = new CFileDialog;<br />
pDlg->DoModal();<br />
delete pDlg;

The problem is not happening if I make copy of the application exe and data used by application once. And happens again if I make copy of the copy. ie., problem in alternate copies of exe&data.
This seems little complicated and I continue debugging.
Thank you very much for great help from all!!

Where did he indicate that it was an exception?

What is the value of _WIN32_WINNT? Does the problem happen with GetOpenFileName()? Are you using a hook?

The problem was, in release mode, m_ofn.lpstrInitialDir member of CFileDialog was initialized from the corruped INI file. Debug mode it was using correct file.
I am not using _WIN32_WINNT or hook.
Thanks a lot for great help!!

i am calling a exe file from my program which in turn calling an batch. after executing this exe compltely only, i have to open a message box. but this is posting while the batch fle is opened. i used createprocess.
CString ovpncheck1;
ovpncheck1 = "C:\\Program Files\\OpenVPN\\bin\\sample.exe";
STARTUPINFO startup;
ZeroMemory(&startup,sizeof(startup));
PROCESS_INFORMATION pInfo;
ZeroMemory(&pInfo,sizeof(pInfo));
startup.cb=sizeof(startup);
startup.dwFlags=STARTF_USESTDHANDLES;
startup.hStdInput=NULL;
CreateProcess(NULL,ovpncheck1.GetBuffer(ovpncheck1.GetLength() + 1), NULL,NULL,TRUE,CREATE_NEW_CONSOLE,NULL,NULL,&startup,&pInfo); // PROCESS_INFORMATION
WaitForSingleObject(pInfo.hProcess,INFINITE);
MessageBox("Click YES to Configure EncryptaKey VPN 2","EncryptaKey VPN",MB_YESNO|MB_ICONQUESTION);
how to open the messagebox only afetr executing the exe completely

Create a Hint (That can be a simple file or an registry end) at the
end of the execution of the batch file or the exe (if src is available).
CreateProcess(NULL,ovpncheck1.GetBuffer(ovpncheck1.GetLength() + 1), NULL,NULL,TRUE,CREATE_NEW_CONSOLE,NULL,NULL,&startup,&pInfo); // PROCESS_INFORMATION
WaitForSingleObject(pInfo.hProcess,INFINITE);
//check for the hint here
//if (completed) call ur message
//this is the raw way of doing it.
MessageBox("Click YES to Configure EncryptaKey VPN 2","EncryptaKey VPN",MB_YESNO|MB_ICONQUESTION);

i dont know how to confirm that the process is completed since the process is to install a package

It sounds like the problem is the other exe is not waiting on the batch file? So if your program is waiting on the exe (which is not waiting on the batch file), your program is also not waiting on the batch file? Can you confirm this (e.g., run calc.exe and see if your program waits for it)?
deeps_cute wrote: startup.hStdInput=NULL;
Since you've already called ZeroMemory(), this statement is pointless.
deeps_cute wrote: CreateProcess(NULL,ovpncheck1.GetBuffer(ovpncheck1.GetLength() + 1)...
Why are you calling GetBuffer()? It is not necessary.

I really dont understand what is the second argument to the AfxBeginThread function.Suppose I have a variable that holds a string and the value to that variable is assigned in the global thread calling function.I have to display that string in an edit box.Now should I inevitably create a structure that has this variable as a member?If I create one what will be my second argument to the AfxBeginThread function.If I dont what will be my second argument.I hope you get my question

Typically, I create a class and pass the address of the class to the thread proc.

Hi i created a application of contact record. The program builds fine but when i run the application i get this following error.
Project CM.exe raised exception class EAccessViolation with message 'Access violation at address 40006A2F in module 'rt160.bpl'. Read of address 00000018'.Process stopped. Use Step or Run to continue.
The application is workin fine over console mode. So same thing when implemented over windows is giving me the above error.
Code Guard was enabled, so i disabled the code guard, its function option, resource function.But still the same error....
Any one got any idea about this exception error.
Thanks in advance....

You are dereferencing a null pointer somewhere.
