SharpTerminal Update: Large DPI Gotchas

Another update to SharpTerminal: this one fixes the large blank spaces on the bottom and right sides of the GUI, as well as a minor startup bug where if you hadn't saved any default settings, and hit Connect without going to the Config tab, you'd get an error. Going to the Config tab and back fixed the problem, but now it shouldn't appear at all.

The GUI bug was an interesting one for me. The computer I write SharpTerminal on had the DPI setting (Display Properties, Settings, Advanced) set to Large (90DPI). So the GUI looked fine on that computer, but it turns out that .Net is smart enough to perform Automatic Control Scaling according to the difference between the developer's settings and the runtime settings. This works great when the developer's settings are Normal and the runtime settings are whatever; Windows Forms scales the GUI appropriately. Things get a little weird when the developer's settings are Large (or possible any non-Normal setting)--as you can see in the screenshot below, on a system set to Normal, the scaling doesn't quite work:

The solution turns out to be fairly convoluted. First, set the developer's computer to use Normal DPI settings and restart the PC. Next, open the solution in VS.Net and go to the code for the form with the issue. Look for a line that says this.AutoScaleBaseSize = new System.Drawing.Size(6, 15); in the Windows Form Designer generated code region, and change the values to 5, 13 (the default values for a Normal system). Open the form in designer mode. Things will likely be very screwed up (controls will run off the bottom and right sides). Fix them. Note that some controls--for instance, the Microsoft ActiveX Web Browser Control--will probably have to be removed and readded in order to work properly. Recompile and the app should look right.

Of course, probably the best idea is for developers to not use strange DPI sizes to develop UIs in the first place. :-P
