Wie Form2 per Button von Form 1 öffnen?

moin2010 · 08.07.10, 13:56

Ich habe Form2.Show schon versucht und da hat es nicht geklappt.
Ich benutze Visual Studio 2010 Express.
Form2 habe ich auch eigefügt bei Form1.

Das ist der code für den button:

Zitat:

private: System::Void button3_Click(System::Object^ sender, System::EventArgs^ e) {

Form2.Show

}

};
}

Dan kommen die Fehlermeldungen:
Fehler 1 error C2143: Syntaxfehler: Es fehlt ';' vor '.' Zeile 231
Fehler 2 error C2143: Syntaxfehler: Es fehlt ';' vor '.' Zeile 231

Hier ist noch mal der Code der Form1 Datei:

Zitat:

Dan kommen die Fehlermeldungen:
Fehler 1 error C2143: Syntaxfehler: Es fehlt ';' vor '.' Zeile 231
Fehler 2 error C2143: Syntaxfehler: Es fehlt ';' vor '.' Zeile 231

Liest du dir eigentlich die Fehlermeldungen durch? Da steht doch dass da ein ";" fehlt.
Außerdem weiß ich immer noch nicht welche Sprache du benutzt..C++? Hab leider nur Basic, aber kannst ja mal versuchen

Code:

Form2->Show();

zu machen..ich würd an deiner Stelle auch lieber erstmal mit Visual Basic anfangen ist viel leichter..

moin2010 · 08.07.10, 14:50

Form2.Show; habe ich ja auch schon probiert.
Ok.
Ich probiere dan mal Visual Basic aus.
Und die Fehlermeldungen lese ich mir natürlich auch durch.

Sry.
Ich benutze Visual C++ 2010 Express.
Geht das auch?
