Debug Assertion Failed

[Davitor]

Thanks for reply. i use debugger but i havn't found that time exception.

void CDelayedDirectoryChangeHandler::On_FileAdded(const CString & strFileName)
{
CStringArray szaddcopyFiles;
CString strFileName;
CString path="D:\\DVD";
szaddcopyFiles.Add(strFileName);

int numofcopyitems = szaddcopyFiles.GetSize();
if (numofcopyitems > 0)
{
tr=1;
for(;aq<numofcopyitems;)
{
finalString=szaddcopyFiles.GetAt(i);

 strFileName1=finalString;
 for(int idc=0;idc<5;idc++)
 {
	AfxBeginThread(WorkerThreadProc1,NULL,THREAD\_PRIORITY\_NORMAL,0,0,NULL);
	WaitForSingleObject(WorkerThreadProc1, INFINITE);
 }

}
}

	if(tr==1)
	{
		
		szaddcopyFiles.RemoveAll();
		tr=0;
	}

}

UINT WorkerThreadProc(LPVOID Param)
{
CFileOperation fo;
CString tr=finalString;

	int nLen = tr.GetLength();
	
	LPCSTR lpszBuf = tr.GetBufferSetLength(nLen);
	tr.ReleaseBuffer(nLen);
	LPCSTR pF=lpszBuf;
	
	
		CStdioFile file;
		fo.SetOverwriteMode(TRUE);
		if(fo.Copy(pF,pT));
		

		//int nPos1121 = finalString.ReverseFind('\\\\');
		int nPos2121 = finalString.ReverseFind('.');

if( nPos2121 > -1)
{
if (file.Open(_T(finalString), CFile::modeRead | CFile::modeNoTruncate))
{

				ULONGLONG dwFileSize;
				dwFileSize = GetFileSize(file,  NULL);
				float fVar;
				str1.Format(\_T("%I64u"), dwFileSize);
				file.Close();
			}
		


	AfxBeginThread(WorkerThreadProccd,NULL,THREAD\_PRIORITY\_NORMAL,0,0,NULL);
	WaitForSingleObject(WorkerThreadProccd, INFINITE);

}
return TRUE;
}
UINT WorkerThreadProccd(LPVOID Param)
{
CFileOperation fo;
CString tr1=finalString;
int nLen1 = tr1.GetLength();
//LPCSTR lpszBuf1 = tr1.GetBuffer(nLen1);
LPCSTR lpszBuf1 = tr1.GetBufferSetLength(nLen1);
tr1.ReleaseBuffer(nLen1);
LPCSTR pF1=lpszBuf1;

	if(fo.Copy(pF1,pT));
return TRUE;

}

Now i hope you will help me..

It would much easier if you provide the exact crash location, and eventually copy the call stack.

crash location showing here.

ATLASSERT( nLength <= GetData()->nAllocLength );

in file atlsimpstr.h. Plz help me..

Provide only the code that has relevance with this issue and take your time to align the code properly. Also, what is tr, finalstring, etc.,? There's a global tr (I don't see it declared anywhere) and another tr inside your worker thread function code with local scope. A perfect recipe for disaster. This is one rare case where I'm going to encourage cross-posting. You may kindly cross-post your code at the coding horror forum too.

Thanks Subramanian ji i had send code where issue will be generated.And next time i align code proper.

[Rajesh R Subramanian]

Hello! Which line of "your" code is triggering this assertion?

[Davitor]

Yes tr, finalstring both are globle. Worker thread it's not tr it is tt.So sorry for that.

[Davitor]

That's a problem Subramanian ji. When i go through Debug then i han't got assertion and when i go through normal mode then i got some time this assertion.This assertion not come regullar.So i han't got exact line of code.If it is possible then help me

It's better if you can try out sample application with minimum code including function that cause the error that will help you to get into exact problem. And it will also helps others to find out exact cause of problem and to give appropriate solution.

[Rajesh R Subramanian]

Try different test cases and narrow down the number of cases for which the crash is occurring. You might as well output text to the debugger window from within your code (if you are not running under the VS debugger, you can still use an external debugger[^] (just connect it to the local machine) and use something like OutputDebugString[^] to print to the debugger). The actual problem might be something as trivial as writing to a pointer that has been released, accessing memory that you don't own, etc., But you need to locate it first.

Thanks for debugger information.How can i use it?

[Davitor]

external debugger

is not working.And i have no idia how to find assertion line plz help me

An assertion is completely different than an exception. So which is it?

0xfeeefeee is a Magic Number[^] which has a meaning. This essentially means that you are trying to access memory AFTER it has been freed. You should begin debugging by checking the variables that you are accessing in your worker thread. Best Wishes, -David Delaune
