Form1->Size... => Error C2143

[Narrow]

Hallo,

Vorweg, ich programmiere normalerweise nichts mit c++ !

Ich muss jetzt aber ein kleines Projekt machen und will darin die Größe meines Windows-Forms ändern wenn ich zwischen den Tabs in meinem TabControl hin und her wechsle:

private: System::Void tabControl1_SelectedIndexChanged(System::Object^  sender, System::EventArgs^  e)
		 {
			 if (tabControl1->SelectedTab->Name == "xxx")
			 {
				 Form1->Size = Size(Point(365, 397));
			 }	 
		 }

Nun bekomm ich (2x) den Error C2143 angezeigt:

error C2143: syntax error : missing ';' before '->'

Hab keine Ahnung an was es liegt

Grüße

Hi,

probier mal

Form1->Size::set(System::Drawing::Size::Size(365, 397));

bei mir klappts so

Viele Grüße

Jo erstmal danke für die schnelle Antwort, leider ist das Ergebnis mit deinem Code genau das selbe...

Form1 scheint mir der Klassenname zu sein und nicht der Name der Instanz, deren Größe du setzen willst.
Irgendwo wirst du so was haben wie:

Form1 ^ form = gcnew Form1();

Das bedeutet, du kannst es dann so ansprechen:

form->Size = //...

Hmm hab nichts derartiges gefunden...

Mir ist aufgefallen, dass ich das Form im Designer gar nicht umbenennen kann!?

Naja ich hab jetzt mal ein neues Projekt aufgemacht, in dem nur ein TabControl (mit 2 TabPages) ist.

-->Selber Fehler

Vielleicht hilfts ja

[DeckCain]

Ersetze mal dein Form1 durch this

this->Size::set(System::Drawing::Size::Size(365, 397));

Woohoo es funktioniert!

1000 dank
