in datei schrieben mit hexcode

Badestrand

Klar funktioniert das auch mit ner Exe-Datei. Aber da wir im WinAPI-Forum sind, hier die WinAPI-Funktionen:
CreateFile
ReadFile
WriteFile
CloseHandle

Edit: Achso, Beispiel...:

HANDLE hFile = CreateFile( "C:\\File.dat", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0, NULL );
if ( hFile != INVALID_HANDLE_VALUE )
{
    DWORD Written;
    WriteFile( hFile, DeinBuffer, DeineBufferGröße, &Written, NULL );
    CloseHandle( hFile );
}

wie geht das damit mach mal beispiel und was muss man includieren?

#include <windows.h>

Beispiel: Siehe Edit... Parameter in der MSDN oder X-beliebiger Windows-Hilfe nachschlagen.

was is mit WriteFile( hFile, DeinBuffer, DeineBufferGröße, &Written, NULL );

gemeint mit buffer?

bin ein kleiner großer noop

Naja, ich schätze mal, du hast deine Daten in einer Variable oder einem Buffer gespeichert. Etwa so:

char a; // Variable
char VieleAs[10000]; // Großer Buffer

In den Variablen kannst du Daten speichern. Und wenn du diese Daten dann in eine Datei speichern willst, musst du die Datenquelle (Variable/Buffer) angeben und halt, wieviele Daten du in die Datei speichern willst.

Angenommen, du willst eine Datei kopieren, aber nicht mit CopyFile, sondern dir selber Code dafür schreiben. Dazu musst du erst die Quell-Datei in einen Buffer einlesen und ihn dann in die neue Datei reinschreiben.
Beispiel:

const char* KopierenVon = "C:\\Datei.txt";
const char* KopierenNach = "C:\\Datei2.txt";

HANDLE hFile = CreateFile( KopierenVon, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL );
if ( hFile != INVALID_HANDLE_VALUE )
{
    DWORD Dummy;
    DWORD FileSize = GetFileSize( hFile, NULL );
    char* Buffer = (char*) LocalAlloc( GMEM_FIXED );
    ReadFile( hFile, Buffer, FileSize, &Dummy, NULL );
    CloseHandle( hFile );

    hFile = CreateFile( KopierenNach, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL );
    if ( hFile != INVALID_HANDLE_VALUE )
    {
        WriteFile( hFile, Buffer, FileSize, &Dummy, NULL );
        CloseHandle( hFile );

        // ERFOLG
    }

    LocalFree( (HANDLE)Buffer );
}

1330 c:\dev-c_~1\include\winbase.h
too few arguments to function `void * LocalAlloc(unsigned int, unsigned int)'

Badestrand

Hab ich halt mal was falsch gemacht...

char* Buffer = (char*) LocalAlloc( GMEM_FIXED, FileSize );

ESS_CB

ich glaub wir sind wieder bei der Diskusion ob man mit MFC oder API arbeiten sollte. Wieso sind nur alle gegen die API??????

alles looserhafter Scriptkidies

und wie könnte man den hexcode einfüfen also als feste variable speichern?

ESS_CB

char s = HEXCODE; //

fwrite(&s,1,1,pfile);

ich bin zu dumm dafür

CodeFinder

Was stellst du dir eigentlich unter HEXCODE vor...? Sowas: 0x0A 0x24 ...

Oder was ?

@ESS_CB: Ich bin auch gegen MFC .

ich meine sowas
