Title: development in Cpp for Kickstart 1.3
Post by: chrisx78 on December 29, 2024, 07:17:01 PM

Hello,
i have try to program a small tool to call whdl images with JST maped with foldername/diskimage.slave. For this I have try to get the current folder with an recursive scan. But this is not successfull, maybe i get here some hints to solve the issue.

Code: [Select]

void initializeTableData() {
BPTR dirLock;
totalRows = 0;

dirLock = Lock("", ACCESS_READ); // Jetzt Lock("") verwenden
if (!dirLock) {
printf("Fehler: Konnte aktuelles Verzeichnis nicht sperren. Fehlercode: %ld\n", IoErr()); [b]// --> Issue here, could not lock the folder.[/b]
return;
}

printf("Debug: Starte Verzeichnisdurchsuchung im aktuellen Verzeichnis.\n");
findSlaveFiles(dirLock, ""); // Leeren String für den Pfad übergeben
UnLock(dirLock);

printf("Debug: Verzeichnisdurchsuchung abgeschlossen. Gefundene Dateien: %d\n", totalRows);
}

void findSlaveFiles(BPTR dirLock, const char *path) {
struct FileInfoBlock *fib = (struct FileInfoBlock *)AllocMem(sizeof(struct FileInfoBlock), MEMF_CLEAR);
if (!fib) {
printf("Fehler: Speicher für FileInfoBlock konnte nicht zugewiesen werden.\n");
return;
}

BPTR subLock;
char fullPath[MAX_PATH];

while (Examine(dirLock, fib)) {
if (fib->fib_DirEntryType > 0) { // Unterverzeichnis
// Pfad zusammenbauen (mit korrekter Behandlung von Slashes)
snprintf(fullPath, MAX_PATH, "%s%s%s", path, (strlen(path) > 0 && path[strlen(path) - 1] != '/') ? "/" : "", fib->fib_FileName);

printf("Debug: Betrete Ordner: %s\n", fullPath);

printf("Debug: Versuche Verzeichnis zu sperren: '%s'\n", fullPath);
subLock = Lock(fullPath, ACCESS_READ);
if (!subLock) {
printf("Fehler: Konnte Ordner %s nicht sperren. Fehlercode: %ld\n", fullPath, IoErr());
}
if (subLock) {
findSlaveFiles(subLock, fullPath); // Rekursiver Aufruf!
UnLock(subLock);
} else {
printf("Fehler: Konnte Ordner %s nicht sperren. Fehlercode: %ld\n", fullPath, IoErr());
}
} else if (fib->fib_DirEntryType < 0 && strstr(fib->fib_FileName, ".slave")) { // Datei
snprintf(tableData[totalRows].slavePath, MAX_PATH, "%s%s%s", path, (strlen(path) > 0 && path[strlen(path) - 1] != '/') ? "/" : "", fib->fib_FileName);
snprintf(tableData[totalRows].displayName, MAX_PATH, "%s", fib->fib_FileName);
printf("Debug: Gefundene .slave-Datei: %s\n", tableData[totalRows].slavePath);
totalRows++;
if (totalRows >= MAX_ENTRIES) break;
}
}
FreeMem(fib, sizeof(struct FileInfoBlock)); //
}

Examine() returns information about the locked directory. In order to get a list of objects inside the directory you have to call ExNext() in a loop.

Thank you so much, thats the right hint.
But now i have the next secret, i want to start the application in the Workbench but the Screen is blue, and thats it..?

Code: [Select]

int wbmain(struct WBStartup *wbStartup) {
BPTR lock;

    // Prüfen, ob das Startverzeichnis übergeben wurde
    if (wbStartup && wbStartup->sm_ArgList && wbStartup->sm_ArgList->wa_Lock) {
        lock = DupLock(wbStartup->sm_ArgList->wa_Lock);
        if (!lock) {
            printf("Fehler: Konnte Startverzeichnis nicht duplizieren.\n");
            return 1;
        }
    } else {
        printf("Fehler: Kein gültiges Startverzeichnis erhalten.\n");
        return 1;
    }

    // Übergabe an die Hauptlogik
  char *argv[] = { const_cast<char*>("WorkbenchStart"), nullptr };

    int result = mainshell(1, argv);

    // Lock wieder freigeben
    UnLock(lock);

    return result;
}

int main(int argc, char **argv) {
    printf("Starte aus der Shell...\n");
    return mainshell(argc, argv);
}

// Prototypen
void initializeTableData();
void drawTable(struct Window *window);
void executeJST(const char *slavePath);
void findSlaveFiles(BPTR dirLock, const char *path);
int mainshell(int argc, char **argv); // Prototyp für mainshell


int mainshell(int argc, char **argv){
    struct Screen *screen;
    struct Window *window;
    struct IntuiMessage *msg;
    BOOL running = TRUE;
   BPTR lock = (BPTR)0;
    char currentDir[MAX_PATH] = "";

    if (argc > 0 && argv[0] != NULL) { // Shell-Start
        char *lastSlash = strrchr(argv[0], '/');

I am not sure what you mean by "the screen is blue". The screenshot looks like your program is running.

yes. only in the shell, the program is do the right stuff.
But if i klick on the Icon in the whdl load icon in the Workbench, everithing is blue like in the Backround. After some time the Amige hangs up and start new
I have attached the Program, you only need the remove the .txt
