Dynamic Labels again!!

hi:

I've created one label array in one form like this:

//first in the beginning of the code,
private System.Windows.Forms.Label mylabel[];

//then inside the button event

this.mylabel = new System.Windows.Forms.Label[1];
this.mylabel[0].Location = new System.Drawing.Point(200, 100);
this.mylabel[0].Size = new System.Drawing.Size(50, 50);
this.mylabel[0].TabIndex = 0;
Controls.AddRange( new System.Windows.Forms.Control[] {this.mylabel[0]});

no problem when compile it, but it got crashed when click the button, what is the problem?

THankx

What line did it crash at ?

If you have Visual Studio, the debugger should show you, if not, put a MessageBox before each line and see which one you get last.

You might want to have a closer look at this line

private System.Windows.Forms.Label mylabel[];

Put the brackets after the type and before the name, unlike C++.

> this.mylabel = new System.Windows.Forms.Label[1];

...does not create a single label. It creates an array of references to labels but does not initialise any of the elements.

mylabel[0] = new System.Windows.Forms.Label();

it crashed always at the first either one of lines:

this.mylabel[0].Location = new System.Drawing.Point(200, 100);
this.mylabel[0].Size = new System.Drawing.Size(50, 50);
this.mylabel[0].TabIndex = 0;


don't know why :(
