4. If Combobox->SelectedItem = "Bla" ( Textbox->Text "bsp")

If Combobox->SelectedItem = "Bla" ( Textbox->Text "bsp")

  • M

    Hallo.

    Mein Problem Code:

    // 
			// textBox2
			// 
			this->textBox2->BorderStyle = System::Windows::Forms::BorderStyle::None;
			this->textBox2->Font = (gcnew System::Drawing::Font(L"Microsoft Sans Serif", 8.25F, static_cast<System::Drawing::FontStyle>((System::Drawing::FontStyle::Bold | System::Drawing::FontStyle::Underline)), 
				System::Drawing::GraphicsUnit::Point, static_cast<System::Byte>(0)));
			this->textBox2->Location = System::Drawing::Point(3, 36);
			this->textBox2->Multiline = true;
			this->textBox2->Name = L"textBox2";
			this->textBox2->Size = System::Drawing::Size(100, 20);
			this->textBox2->TabIndex = 15;
			if(comboBox1->SelectedItem=="XXX")
			{
				this->textBox2->Text = L"YYY";
			}

    Wo liegt der Fehler denn a.) Der Entwurf wird mir nur noch in HtmL angezeigt, b.) wird der Text nicht angezeigt, wenn if = true

    Hier mal der ganze Code:

    Das findest Du bestimmt selbst raus.
    Benutz doch den Debugger.

    Und wie? Angeblich ist ja kein Fehler da... Läuft ja alles außer ein "Internal" Error beim Entwurf... Aber der TExt wird nicht ausgegeben!

    Der Debugger benutzt man zur Laufzeit (=wenn das Programm läuft).
    Der Compiler / Linker sagt dir was falsch ist zur Compile / Link Time.

    Also, benutz den Debugger.

    Edit:
    Ich bin wohl auf den selben Fehler heringefallen wie alle anderen - Das Programm stützt nicht ab der Designer meckert rum - zu recht:

    http://www.c-plusplus.net/forum/viewtopic-var-t-is-263084.html

    Wenn du in InitializeComponent herumfummelst, kann kann der scheiss Designer das nicht mehr lesen und dan meckert der Designer. Verscheibe also deinen Code irgendwo anders hin und lass InitializeComponent in Frieden.

    Noch schnell mal eine Frage hinterher:

    private: System::Void button1_Click_1(System::Object^  sender, System::EventArgs^  e) {
			 OpenFileDialog ^ openFileDialog1 = gcnew OpenFileDialog(); 
                openFileDialog1->InitialDirectory = "C:\\"; 
                openFileDialog1->Filter = ""; 
                openFileDialog1->Title = "Bild auswählen"; 

                if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK){ 
					this->foto->Image = Image::FromStream (*openFileDialog1);
                }
		 }

    Ich möchte das Bild was ich auswähle in der PictureBox = foto anzeigen lassen. Doch es funktioniert nur wenn ich statt this->foto this->textBox1 nehme (oder andere textboxen). Wo ist mein Fehler?

    Danke 🙂

    (Edit: Ja, ich will nur das Programm noch in C++ schreiben und steige dann auf C# um... Total dämlich, habe Viszal Studio 2008 Professional Edition (oder so) und kann kein MFC machen... Wenn ich ein MFC Projekt erstellen will geb ich Namen ein und klick Enter und es erscheint nur ein neues kleines Fenster mit einem riesig langen HTML Code oder XHTML welchen ich nicht mal kopieren kann... Also scheint irgend ein Fehler zu sein -.- Dafür gibt man Geld aus -.-)
