    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?

    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++.

    When in doubt, read the FAQ.
    Then ask a smart question.

    > 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
