Mach erstmal aus

BitBlt("screenie.bmp",0,0,640,480,hBIT,0,0,PATINVERT);

HDC dc_dest = CreateCompatibleDC(hDC); // kompatiblen zieldc anlegen
HGDIOBJ old = SelectObject(dc_dest, hBit); // selektieren und altes objekt behalten
BitBlt(dc_dest,0,0,640,480,hDC,0,0,SRCCOPY); // blitten
SelectObject(dc_dest, old); // aufräumen
DeleteDC(dc_dest); // aufräumen

So, jetzt solltest du das Bild in hBit haben. Gleich gehts hier weiter...

Fake oder Echt

Bin mir nicht ganz sicher, aber schau mal in der GDI+ bei der Bitmap-Klasse nach. Die nimmt iirc u.a. ein HBITMAP (also handle) im Konstruktor an, um ein Bitmap-Objekt zu erzeugen. Da müsste es eine Methode geben, die die ganze Sache recht einfach als Datei speichert. Aber alles erstmal ohne Gewähr!

ahh dann hatte ich das doch schon richtig gesehen, ok danke

mad_martin

So, nun noch das Speichern:
Hier ist der Konstruktor der Bitmap-Klasse aus GDI+, den ich meinte:
http://msdn2.microsoft.com/en-us/library/ms536314(VS.85).aspx

Über die benötigte Palette bin ich mir nicht mehr ganz im Klaren, da das schon einige Zeit her ist. Glaube, die kann man u.U. ignorieren. Wäre schön, wenn hierzu noch jemand eine Antwort hätte!

Naja, gespeichert wird auf jeden Fall mit:
http://msdn2.microsoft.com/en-us/library/ms535407(VS.85).aspx

Den richtige Encoder auszuwählen überlasse ich dem geneigten Leser

Sorry dass ich erst so spät antworte, aber ich habe jetzt ne Zeit probiert und gesucht, doch wo kriege ich die gdiplus.h her die ich einbinden muss?

Zu finden z.B. im "Windows SDK" oder "Platform SDK"

Ok, ich mal wieder. Hab das Platform SDK runtergeladen, alles installiert usw. jetzt will ich kompilieren und:

Jede Menge Fehler, woran liegts?

Weiß wirklich keiner woran es liegt?
