问题 We are building a Windows application in .NET and one of its requirements is touch screen monitor. Other than that, it's a normal windows form based application. But except for making UI items little bigger for touch, I can't find anything I as a developer need to do for the requirement since touch screen is basically mouse operations.

This may take several minutes"; string v = foo(); txtOutput.Text += "\n" + v; string b = bar(); txtOutput.Text += "\n" + b; txtOutput.SelectionStart = txtOutput.Text.Length; txtOutput

问题 I want to create a WinForms app that can detect location just like a web browser would using the javascript function navigator.geolocation.getCurrentPosition(showPosition); Is there some way to do this in WinForms directly? I thought that I might be able to use the WebBrowser control to do this but I don't believe this supports Geolocation (unless someone knows otherwise?) Apparently the Gecko browser does support gelocation but this is not an option for me because client may have a different

问题 How do I detect if a device is touch-enabled in c# for a WinForms app (Not WPF). I found information on GetSystemMetrics...can't find how to use this in c#.
