Basic example script that prompts a file selection dialog and writes "a\n" into the file

int GetSaveFile() {
    OPENFILENAME ofn;
    char szFileName[MAX_PATH] = "";

    ZeroMemory(&ofn, sizeof(ofn));

    ofn.lStructSize = sizeof(ofn);
    ofn.hwndOwner = NULL;
    ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
    ofn.lpstrFile = szFileName;
    ofn.nMaxFile = MAX_PATH;
    ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
    ofn.lpstrDefExt = "txt";

    if(GetSaveFileNameA(&ofn)) {
        FILE* file = fopen(szFileName, "w");

        if (file == NULL) {
            fprintf(stderr, "Unable to open file\n");
            return 1;
        }

        fprintf(file, "a\n");

        fclose(file);
    } else {
        fprintf(stderr, "No file selected\n");
        return 1;
    }

    return 0;
}
