Ich brauche Hilfe bei meinem Programm, da ich noch Neuling im Bereich Windows-Programmierung bin. In mein einfaches Programm möchte ich eine BMP-Datei in den Puffer laden, aber trotz mehrerer Versuche mit Beispielen hat es nicht funktioniert. Was mache ich falsch?

I made these examples some year ago, reading some file graphics putting them in memory, but just in c, asm version are not ready. There may be standard Windows functions that handle it in a more orthodox way; in my case, I did it by reading directly from the file.

Your program is a bit long to read it easy and German comments are still a bit challenge for me Smile

Were you just concerned with the commented portion?

Code:

hFile           dq ?    ; HANDLE
fileSize        dq ?    ; uint
pBuffer         dq ?    ; VOID*
bytesRead       dd ?    ; uint

invoke CreateFileA, "Logo.bmp", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NUL
mov [hFile], rax

invoke GetFileSize, [hFile], NULL
mov [fileSize], rax ; assume high-dword zero

invoke VirtualAlloc,NULL, [fileSize], MEM_COMMIT or MEM_RESERVE, PAGE_READWRITE
mov [pBuffer], rax

invoke ReadFile, [hFile], [pBuffer], [fileSize], addr bytesRead, 0

invoke CloseHandle, [hFile]

... perhaps?
