picturebox.visible problem

bimbambumbum

Hi I'm a newbie struggling with a picturebox. At construction time I load a jpg image into a picturebox and I have 3 radio-buttons that dictate what what is drawn in the GUI. When the picturebox is enabled & visible at construction time then it stays visible even if I make it invisible later by pressing a radiobutton (picturebox1.visible = false) . Can someone please tell me what I'm missing? Regards Tom

Hmm, just solved it myself... when I replace: BitmapCanvas.Visible = false; With: this.BitmapCanvas.Visible = false; Then I can make the visible picturebox go invisible! Wonder why that is needed? Probably a no-brainer Thomas

This problem happens when you have a parameter or variable in a method that has the same name as the field of a class, such as:

class MyClass
{
private int value;

public MyClass(int value)
{
    // value refers to the parameter
    // to use the field, as it has the same name, use this.value
    this.value = value;
}

}

You can tell by hovering the mouse over value in the code editor.

hover BitmapCanvas, right-click for "Go to definition" and see if that is what you expect it to be. :)
