Hallo,
ich lese ein Unicode Logfile mit CFile::Read aus. im alten VC6 lief alles problemlos, nur jetzt im VC7 meckert er beim Verlassen der function und sagt folgendes:
run-time check failure #2 - stack around the variable buffer was corrupted
da ich unicode auslese, habe ich den buffer auf die hälfte der auszulesenden bytes gesetzt, da ein unicode zeichen ja 2 bytes hat. ich denke es hängt irgendwie damit zusammen.. hat jemand eine idee? ich weiß echt nicht mehr weiter!
Hier mal der gesamte code:
| C++: |
void CCompDoc::ReadFileIntoDataStructure(CFile* pFile, CString sDisplayName, COLORREF crFontColor)
{
DWORD dwRead;
const unsigned int iBufferSize = 256;
wchar_t buffer[iBufferSize/2];
wcsset(buffer,0);
int len = wcslen(buffer);
CString sTarget; //(buffer);
CString tmp ="";
int crPos;
LogFile *lFile = new LogFile();
BOOL ok = TRUE;
dwRead = pFile->Read(buffer, 2); //liest die ersten 2 BYTES aus --> UNICODE Kennzeichen
int counter=0;
do {
dwRead = pFile->Read(buffer, iBufferSize);
sTarget+= _T(buffer);
if (dwRead<iBufferSize) {
/* this is only for the last read operation, where dwRead<iBufferSize
in this case the last (unnecessary) chars will be removed
*/
sTarget = sTarget.Left(sTarget.GetLength() - (iBufferSize - dwRead)/2);
if (dwRead==0) //adds an additional linebreal and eof-->make sure to get last line
sTarget = sTarget + (char(13)) + ((char)10);
}
do {
while ((sTarget.GetLength()>0) && ((sTarget.GetAt(0)==13) || (sTarget.GetAt(0)==10))) {
/* removes the chars for value 10 or 13 (linebreak) until the
first charvalue is unequal to (char) 10 or (char)13
*/
sTarget.Delete(0, 1);
}
// look up for linebreak
crPos = sTarget.Find((char)13, 0);
if (crPos!=-1) {
// if linebreak found add all chars until linebreak-position
// as a entry in current logfile
tmp = sTarget.Mid(0, crPos);
sTarget.Delete(0, crPos);
if (lFile->AddEntry(tmp) == TRUE) {
counter++;
}
else {
AfxMessageBox("Error converting time-value in this Line:\n"
+ tmp + "\n"
+ "in File: " + sDisplayName);
}
}
}
while (crPos!=-1);
}
while (dwRead>0);
lFile->SetTotalEntries(counter);
lFile->SetFileName(pFile->GetFilePath());
lFile->SetDisplayName(sDisplayName);
lFile->SetFontColor(crFontColor);
lFile->SetVisible(TRUE);
m_oaLogFiles.Add(lFile);
m_iOpenLogFileCounter++;
//wcsset(buffer,0);
}

Vieln Dank schonmal! |
