windows app in CLR

[chipp]

i have a difficulties in CLR's, how to use "click" event? i have like this:

#pragma endregion //btw, can anyone explain to me what pragma's doin'?
	private: System::Void btn_result_Click(System::Object^ sender, System::EventArgs^ e) {
			int i, j, k;
			i = Int32::Parse (textBox1->Text);
			j = Int32::Parse (textBox2->Text);
			k = i + j;
			textBox3->Text = k.ToString();
		}

but it doesn't works... am i doin' somethin' wrong?

In what way does it not work?


P.S.
The pragma is to to with code folding in the editor. You should have coresponding #pragma region [some lable text here] and a small box with a minus sign, if you click that the code between the pragmas is hidden

the "Click" event doesn't appear the result in "textBox3". it just didn't work...

edit: i just try it again but by double-click the button in design mode and add the code above:

			int i, j, k;
			i = Int32::Parse (textBox1->Text);
			j = Int32::Parse (textBox2->Text);
			k = i + j;
			textBox3->Text = k.ToString();

and it work... but i don't understand, i try it before with exact same code (i press F7 to edit the code, not double-click the button picture in design mode) but it didn't work. really strange...

It is not strange at all. By double-clicking, you invoked the default event writer in Visual Studio, which writes code in the designer that links the function btn_result_Click() to the click event of the control. If you just write the event in the form class but don't explicitly link it to the event, then it is never invoked.
