CreateFile returns invalid handle value when I use wcscpy in my source... ...need a help.

[MIUSS]

Hello

I got an unusual problem and I don't know how to solve it out.

I need to get success with the handle variable hFile. It's not problem
'til I use wcscpy(...). I mean, when I take out those two double-
slashes the source is not working and the func CreateFile returns
0xFFFFFF to that variable. It seems to me that it has some context
with using wcscpy? But why?

void SaveWorkerFile(void)
{
TCHAR szSoubor[MAX_PATH];//

int StrLength;
LPTSTR lpBuffer;
WCHAR temppp[200];
WCHAR UnicodeIdr[10];
HANDLE hFile;

UnicodeIdr[0] = 0xFEFF; UnicodeIdr[1] = 0x0000;
// wcscpy(temppp, UnicodeIdr);
// wcscat(temppp, TEXT("MK00000000 01/01/07 REZIEROTEC
PocetHodin Popis \r\n"));

StrLength = lstrlen(temppp)+10;

lpBuffer = (LPTSTR)HeapAlloc(GetProcessHeap(), 0, StrLength);
GetWindowText(hWndDatabaseWindow, lpBuffer, StrLength);
wcscpy(lpBuffer, temppp);

DWORD dwZapsano;
lstrcpy(szSoubor, TEXT("C:\\RCOMMISIONS\\mkatab.txt"));

hFile = CreateFile(szSoubor, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS,
0, NULL);
if(hFile == INVALID_HANDLE_VALUE) return;
if(!WriteFile(hFile, lpBuffer, StrLength-1, &dwZapsano, NULL))
MessageBox(g_hWnd, TEXT("Error in writing file process."),
TEXT("Error"), MB_ICONERROR);
CloseHandle(hFile);
HeapFree(GetProcessHeap(), 0, lpBuffer);

return;
}

Any help will be apprecciated.

Have a nice day

Getting repetitive tonight...

This looks horribly like widows code, so you'd better post to windows
development group.

Thee is no wcscpy() nor CreateFile() in the standard C++ library.

Hello everyone,

I've found the fault and already have solved this problem. I used too
much long string in func wcscpy in TEXT("...") which resulted in
invalid handle value then. Thank you for your willigness and have a
nice day

Later I get to know that it isn't neither because of long string in
TEXT(...)... So I don't know where the fault come from. There must be
some stupid bug. I've gave up and I've had to copy my older code where
I hadn't any problem with invalid handle value... I've copied it to my
new project and it works fine.. It's almost the same I only use TCHAR
instead of WCHAR and lstrcpy instead of wcscpy...

Thee is no wcscpy() nor CreateFile() in the standard C++ library.

wcscpy is part of the standard C library, and therefore part of the
standard C++ library too.
