Hi all,

I receive the following error:
Unhandled exception at 0x0045b287 in updCnf32.exe. 0xC0000005: Access violation writing location 0x00666e63.

Code (xutilty : compiler open this file):

inline void __CLR_OR_THIS_CALL _Container_base::_Orphan_all() const
	{	// orphan all iterators
	_Lockit _Lock(_LOCK_DEBUG);
	if (_Myfirstiter != _IGNORE_MYITERLIST)
		{
		for (_Iterator_base **_Pnext = (_Iterator_base **)&_Myfirstiter;
			*_Pnext != 0; *_Pnext = (*_Pnext)->_Mynextiter)
			(*_Pnext)->_Mycont = 0; // EXCEPTION HAPPENS HERE
		*(_Iterator_base **)&_Myfirstiter = 0;
		}
	}

This is my code:

for(int i=0; i < (int)getFileNamesString.size(); i++)
{
    getFNamesString = CIniFile::GetSection(getFileNamesString[i], applicationFname);
    for(int i=0; i < (int)getFNamesString.size(); i++)
        cout << "File Names -> " << getFNamesString[i].Key.c_str() << "=" << getFNamesString[i].Value << endl;
}
string FileName = getFNamesString[0].Value;     // UPDATER
string updateFName = getFNamesString[1].Value;  // UPDATE

printf("Creating Directory\n");
TCHAR szDirPath[] = TEXT("C:\\Test\\");
if (!CreateDirectory(szDirPath, NULL))
{
  printf("Could not create new directory.\n");
  getch();
  return -1;
}
else
    printf("Directory Created...\n\n");

strcat((char*)szDirPath, (const char*)updateFName.c_str());
char lpExistingFileName[BUF_SIZE];
char lpNewFileName[BUF_SIZE];
strcpy((char*)lpExistingFileName, (const char*)updateFName.c_str());
strcpy((char*)lpNewFileName ,(const char*)szDirPath);
if(CopyFile((LPCTSTR)lpExistingFileName,(LPCTSTR)lpNewFileName,FALSE))
    printf("File was copied successfully...\n");
else
    printf("File copy failed....\n");


bool SecRc = false;
vector<string> getSecNameString = CIniFile::GetSectionNames(FileName);
for(int i=0; i < (int)getSecNameString.size(); i++)
{
    vector<CIniFile::Record> getSecString = CIniFile::GetSection(getSecNameString[i], FileName);
    for(int i=0; i < (int)getSecString.size(); i++)
    {
        if (CIniFile::SetValue(getSecString[i].Key,getSecString[i].Value,getSecString[i].Section,updateFName))
            SecRc = true;
        else
            SecRc = false;
    }
}

if (SecRc)
    printf("\nSuccess...\nPress any key to continue....");
else
    printf("\nFailed...\nPress any key to continue....");
getch();
return 0;

Many thanx ( .. Confused | :confused:

Did you use your debugger to see where the problem in your code is ? Can you tell us more about where it happens and what are the value of your variables at this point ?

Thanx for the reply Cedric,

The exception happens right at this point:
As I press any key, for the getch() the exception occurs.

    getch();
	return 0;
} // END OF PROGRAM

Does this help?

I get a feeling that the stack has become corrupted. Check the memory allocations. If you can't find it that way, try to comment out portions of the code until you can pinpoint the location of the source of the error.

O.k I have done what you said and I have located the place where it happens, can you see anything wrong here:

strcat((char*)szDirPath, (const char*)dtStamp);
char lpExistingFileName[BUF_SIZE];
char lpNewFileName[BUF_SIZE];
strcpy((char*)lpExistingFileName, (const char*)updateFName.c_str());
strcpy((char*)lpNewFileName ,(const char*)szDirPath);
if(CopyFile((LPCTSTR)lpExistingFileName,(LPCTSTR)lpNewFileName,FALSE))
    printf("File was moved successfully...\n");
else
    printf("File move failed....\n");

Many thanx

Got it ...

#define BUF_SIZE 1000

char szDirPath[BUF_SIZE] = "C:\\CNF_Update_Transactions\\";

Yes, you did.
I couldn't verify your code, since you didn't supply the variable declarations.
But anyhow, the problem is fixed, that's the main thing.
And you got a lesson about what happens in case of a stack corruption. Strange things happens...

hi,
I've a question.
Can use a class written in a file (fileA.cpp) and use the funtion from the class in another file(fileB.cpp) for example?

Offcourse.. just include the header file containing the definition of class most probably fileA.h, define an object wherever u want to use the functions of the class and call them. Simple ehh :P

I am getting an exception while start running my project. i am included some 6 dll's and each dll is working and verified.

The error message shows,

"The application failed to initialize properly (0xc0000142). Click on OK to terminate the application"

"Unhandled exception in LFATE.exe (NTDLL.DLL): )xc0000142: DLL Initialization Failed"

I would guess DLLMain is returning FALSE in response to the DLL_PROCESS_ATTACH notification and you're statically linking to the DLL.

Just run the app in a debugger and watch the output. I made a test app to reproduce the problem and here's the output MSVC6 produced:

Loaded 'ntdll.dll', no matching symbolic information found.
Loaded 'C:\WINDOWS\system32\kernel32.dll', no matching symbolic information found.
Loaded symbols for 'C:\Projects\Scratch\StaticLinkProblem\Debug\ProblemDLL.dll'
First-chance exception in StaticLinkProblem.exe (NTDLL.DLL): 0xC0000142: DLL Initialization Failed.

The line in question is "Loaded symbols for 'C:\Projects\Scratch\StaticLinkProblem\Debug\ProblemDLL.dll'"; the last DLL load reported before the problem occured.
