Wie erzeuge ich Link-(*.lnk)Dateien?
-
Eines meiner Programme soll 'Link'-Dateien selber erzeugen. Das Problem ist nur, ich weiß nicht wie man das macht!
Kann mir dabei jemand helfen?

I'm back
Also, es gab da mal vor Zeiten einen Beitrag, in welchem ausführlich eine API-Fuktion erklärt wurde mit welcher man solche LNK-Verknüpfungen anlegen kann.
Ohne groß rumzureden schicke ich dir einfach mal den Code:#include <shlobj.h> //---------Typedefs-----------------------------------------------------------// typedef IShellLink *LPSHELLLINK; typedef IPersistFile *LPPERSISTFILE; /******************************************************************************/ /* CreateShortcut: Hilfsfunktion zur Erzeugung eines Shortcuts */ //----------------------------------------------------------------------------// /* Parameter: pszPath - Pfad, auf den der Shortcut verweist */ /* pszArguments - Programmargumente */ /* pszLocation - Wo und unter welchem Namen soll der */ /* Shortcut gespeichert werden? */ /* pszWorkingDir - Arbeitsverzeichnis */ /* pszIcon - Icon */ /* nCmdShow - Wie soll das Applikationsfenster */ /* nach dem Start dargestellt werden? */ /* */ /* Rückgabewert: TRUE - Shortcut wurde erzeugt */ /* FALSE - Fehler */ /******************************************************************************/ BOOL CreateShortcut( LPSTR pszPath, LPSTR pszArguments, LPSTR pszLocation, LPSTR pszWorkingDir, LPSTR pszIcon, int nCmdShow ) { LPSHELLLINK pShellLink; HRESULT hrCoInit; // OLE-Installations-Ergebnis HRESULT hr; // Ergebnis der Objektmethoden hrCoInit = CoInitialize(NULL); // OLE initialisieren hr = CoCreateInstance(CLSID_ShellLink, // ShellLink-Objekt erzeugen NULL, CLSCTX_INPROC_SERVER, IID_IShellLink, (void**)&pShellLink); if(SUCCEEDED(hr)) { LPPERSISTFILE pPersistFile; // PersistFile Interface ermitteln -------------------------------------- if(SUCCEEDED(pShellLink->QueryInterface(IID_IPersistFile, (void**)&pPersistFile))) { WORD wsz[MAX_PATH]; // Programmpfad setzen ---------------------------------------------- hr = pShellLink->SetPath(pszPath); // Argumente setzen ------------------------------------------------- if(SUCCEEDED(hr)) hr = pShellLink->SetArguments(pszArguments); // Arbeitsverzeichnis setzen ---------------------------------------- if(SUCCEEDED(hr)) hr = pShellLink->SetWorkingDirectory(pszWorkingDir); // Icon setzen ------------------------------------------------------ if(SUCCEEDED(hr)) hr = pShellLink->SetIconLocation(pszIcon, 0); // ShowCommand setzen ----------------------------------------------- if(SUCCEEDED(hr)) hr = pShellLink->SetShowCmd(nCmdShow); // Pfad setzen, an dem Shortcut abgespeichert werden soll ----------- if(SUCCEEDED(hr)) { MultiByteToWideChar(CP_ACP, 0, pszLocation, -1, wsz, MAX_PATH); hr = pPersistFile->Save(wsz, TRUE); hr = pPersistFile->SaveCompleted(wsz); } //******************************************** // hr = pPersistFileRelease(); //******************************************** } pShellLink->Release(); } // Wenn OLE hier initialisiert wurde, muß es auch hier wieder deinstalliert // werden if(SUCCEEDED(hrCoInit)) CoUninitialize(); return SUCCEEDED(hr); }Das ist alles was du dafür brauchst

Danke für den Code!

In Konsole erzeugt man das wie folgt:
