Event on KeyPress

[Polar_Sheep]

Thanks, but I still not work. I have this: void textBox1_KeyDown( Object^ /*sender*/, System::Windows::Forms::KeyEventArgs^ e ) { if ( e->KeyCode == Keys::Enter) textBox2->Text = "Enter was pressed"; }

Maybe try setting the TextBox's AcceptsReturn property to true. Mark

AcceptsReturn True... Still is not work. Shall I have some code in Initialize component? I mean something like this: this->textBox1->KeyDown = gcnew... something?

Yes you need to create the delegate and add it to the event. Can you show that code? Mark

In initializeComponent(), create a delegate and add it to textBox1's KeyDown event:

this->textBox1->KeyDown += gcnew System::KeyEventHandler(this, &Form1::textBox1_KeyDown);

'void PoHavarii::Form1::textBox1_KeyDown(System::Object ^,System::Windows::Forms::KeyEventArgs ^)' : the specified function does not match the delegate type 'void (System::Object ^,System::EventArgs ^)' It needs other function, but we are on the right way :) Many thanks

this->textBox1->KeyDown += gcnew System::Windows::Forms::KeyEventHandler(this, &Form1::textBox1_KeyDown); :-D Thank you very much and sorry for your time

Oops! You got it :)

I assume you added the TextBox to your form using the designer. An easy way to add events to a control is to view the Properties window for the control (just right-click on the TextBox and select Properties if it's not already showing). The default view shows most of the public properties you can access for that control (things like Text, Enabled, Visible, Height, etc.). There's a button with a lightning bolt at the top of this window. Clicking this button will show all the events this control has. Double-clicking on an event will automatically insert the function and link it to your control in InitializeComponent(). Slightly longer explanation than I wanted, but once you walk through it, it's really easy. I just with it would place the function definitions in Form1.cpp instead of Form1.h :) - dybs
