• Visual Studio Array Help Docs Wrong

  The c# help docs say you can declare an array with an initial value like this: int[] myIntArray2 = new int = {1, 2, 3, 4, 5, 6}; However this will not compile, you have to use the following method int[] i = new int[2] {1, 2}; I tried to report this through the help docs comment, but could not get it to work. That example is definitely incorrect. Single dimension arrays are initialized using either one of these two forms: int[] a = {0, 2, 4, 6, 8};             int[] a = new int[] {0, 2, 4, 6, 8}; But I cannot find the statement you mention in our ...Show All

• Visual Studio Creating "ASP.NET WebSite" project using Automation - bug?

  I'm trying to create a new "ASP.NET Web Site" project (like the user would do using the File->New WebSite menu item) and running into problems. I've used these functions to create Class Libraries and Windows applications before, so I'm pretty familiar with them. however I'm unable to find the right Template name for a Web Site project. I'm using EndDTE80.GetProjectTemplate(TemplateName,Langauge) to get the template path and then using EnvDTE80.Solution80.AddFromTemplate() to create the new project. As i've said before, I've done this a lot using "WindowsApplication.zip" for the template name or "ClassLibrary.zip" and it works great. These ...Show All

• Visual Studio Express Editions How can I make ....?

  Well, The main is that I want to make the program alert me what key was press when that key is pressed. How can I make that Or If there is a good tutorial for starting programming in C# Thanks If you mean a key press across the entire system, then you need to write a system wide hook. Not sure if you can do this in C#, you can in C++. If you mean within your app, when your window has the focus, if you create a WinForms app, and then in the designer look at the properties window, there's a lightning flash icon you can click, then you get a list of events you can be notified of in your program. The KeyPress event is called when ...Show All
