How can I get the correct width of my form?
0
When using the following code to get the size of a form and the position another form to the left of it the size of the form returned seems to be larger than it should be.
//form is the name of the second form that I'm trying to
//position to the left of this form
form.Left = this.Left - form.Width;
Back in the vb6 days I would use something like SaleWidth instead. Is there something like that that I need to use in c#? Or is this due to for shadows etc? How can I get my second form to end up right next to the current form?

The width property is the "client width" (i.e., the width of the client area of the form) I believe, and not the overall outer width of the form. There's a way to figure this out by looking at all the properties, but I can't remember what that is.

The apparent gap between the forms is due to the window's theme. The theme makes the form's non-client area border transparent. If you make a call to the API method SetWindowTheme to remove the theme, you will observe that your calculation is correct. i.e.SetWindowTheme(this.Handle, " ", " ");. A hack is to adjust the width by:(SystemInformation.FrameBorderSize.Width + SystemInformation.SizingBorderWidth).

@Flydog57 No, you have it the other way around. ClientSize is the interior size, Width would be the overall width of the form, which is a fantasy number, since Windows lies about the overall width of a form due to those fancy border shades.
