Owned Forms Question

[Kirk_G]

In my program I have custom dialog box that might or might not be open. If the dialog box is open I would like the program to update it at certain times. When I create the dialog box I make it owned by the main program.

 

foreach(Form f in this.OwnedForms)

{

customDialog tempDialog = (customDialog)f;

tempDialog.Zmax = blah;

tempDialog.Zmin = blah;

tempDialog.AutoScaleZ = blah;

}

 

this works fine for now because this dialog box is the only thing that the main program owns. My question is, how can I setup an if statement that only accepts when f is a customDialog box? I tried things like:

 

if(f == customDialog)

if(f == typeof(customDialog))

if(typeof(f) == typeof(customDialog))

 

but all of these caused errors. Any ideas would be appriciated. Thanks

Try

 

if (f is customDialog){...}

That worked perfectly, thanks again for fixing my code JABE!!
