Assertion Error :(

I am getting this error only when compiling in debug mode. It saves the files alright but I get this after I close the window.

Code:

int SaveClientInfo(HWND DialogHandle)

{


	HANDLE File;
	Client Cliente;
	HWND NameEditBoxHwnd;
	HWND NameEditBox;
	DWORD dwWritten;
	HWND  AddressBoxHandle;
	char * NameOfFile;
	char *FileToSave;
	char *NameOfClient;
	char *ClientAddress;
	int iCount;

	ZeroMemory(&Cliente,sizeof(Cliente));

	

	NameEditBoxHwnd=GetDlgItem(DialogHandle, IDC_NOMBRE);
	iCount=GetWindowTextLength(NameEditBoxHwnd);
	
	//we incremente iCount to accomodate for the NULL character
	NameOfFile=new char [iCount];
	GetWindowText(NameEditBoxHwnd,NameOfFile,iCount+1);
	FileToSave= new char [sizeof(NameOfFile)];

	
    OpenFileName.hwndOwner         = NULL;
    OpenFileName.lpstrFile          = NameOfFile;
   OpenFileName.lpstrFileTitle	   =FileToSave;
    OpenFileName.Flags              = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT ;
	
	GetSaveFileName (&OpenFileName);

		
	NameEditBox=GetDlgItem(DialogHandle, IDC_NOMBRE);
	iCount=GetWindowTextLength(NameEditBox);
	NameOfClient=new char [iCount];
	GetWindowText(NameEditBox,NameOfClient,iCount+1);
	Cliente.SetName(NameOfClient);




	AddressBoxHandle=GetDlgItem(DialogHandle,IDC_ADDR);
	iCount=GetWindowTextLength(AddressBoxHandle);
	ClientAddress=new char [iCount];
	GetWindowText(AddressBoxHandle,ClientAddress,iCount+1);
	Cliente.SetAddress(ClientAddress);




	File=CreateFile(OpenFileName.lpstrFileTitle, GENERIC_WRITE, 0, NULL,
        CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

		                    

    WriteFile(File, (char*)&Cliente, sizeof(Cliente), &dwWritten, NULL);
                      


	/* I am having some serious problems with this stuff
	upon closing the window the program crashes....
	how would I free the pointer memory? 

	delete Pointer;
	Pointer=NULL;

	Should  I do this here? 
	Remember that this is called more than once thruout the program
	I think that it's because I am not freeing memory properly

   */

	GlobalFree(NameOfFile);
	GlobalFree(FileToSave);
	GlobalFree(NameOfClient);
	GlobalFree(ClientAddress);


	CloseHandle(File);





	return Success;

	
	
}

What I've found wrong so far:

Code:

NameOfFile=new char[iCount];
GetWindowText(NameEditBoxHwnd, NameOfFile, iCount + 1);

should be:

Code:

NameOfFile=new char[iCount + 1];
GetWindowText(NameEditBoxHwnd, NameOfFile, iCount + 1);

You need one more char for the null character.

Code:

FileToSave= new char[sizeof(NameOfFile)];

NameOfFile is char* so sizeof(NameOfFile) == 4, use iCount + 1 instead.
