• .NET Development Performance of Type.InvokeMember vs MethodInfo.Invoke

  At first glance I'd say MethodInfo.Invoke() would obviously be faster than Type.InvokeMember(). I just wrote a little program to verify that assumption: Type myObject = ... int numTries = 1000; MethodInfo method = myObject.GetMethod( "StaticMethod" , BindingFlags .Static | BindingFlags .Public); DateTime startInvokeMethod = DateTime .Now; for ( int i = 0; i < numTries; ++i) method.Invoke( null , null ); DateTime endInvokeMethod = DateTime .Now; txtOutput.Text += "\r\nTime taken to invoke " + numTries + " times on method: " + (endInvokeMethod - startInvokeMethod).ToString() + " secs\r\n" ; DateTime startInvokeOnType = DateTime .Now; ...Show All

• Visual Studio 2008 (Pre-release) MSDN Managed Newsgroups for WPF?

  Are there any plans to provide Managed Newsgroup support for WPF and the rest of .Net 3.0 It seems strange that there are some 230 managed newsgroups, including WinForms, but nothing for Microsofts new flagship UI. -- Just feeling a little disgruntled here because more often than not, when I ask a question nobody has an answer. Michael Hi Rob, Did you get any further with this A couple of other links:- http://msdn2.microsoft.com/en-us/subscriptions/aa974230.aspx http://msdn.microsoft.com/newsgroups/managed/default.aspx I've found the managed groups incredibly useful in the past as you can rely on getting a fairly authorative answer to more difficult or subtle question ...Show All

• Visual C++ modal dialog box not closing quickly enough

  Hi. I have a single threaded MDI application with several windows that are concurrently open and displayed during normal operation. I need to print the contents of a user-selected window. Per end-user request I display a CDialog based modal dialog box that allows the user to select the window he wants to print and then click on the OK button. I have code that then takes a bitmap snapshot of the requested window and prints it to the printer(from KB article q186736). So far so good, but if the dialog box overlaps the window that the user wants to print, the overlapping part of the dialog box is also printed. This doesn't make sense to me - the dialog should completely go away as I understand it. FWIW here's a code snippet: ...Show All

• Software Development for Windows Vista vista blocks application at startup

  Hi, I'm a software developer and I have a question about Vista. Our application (a .NET 1.1 app) requires Administrator access and we have the "requiresAdministrator" access level defined in the application manifest. That part is working fine. However, our application needs to startup when the computer boots so we have it in the "startup" folder. For some reason (I can't imagine why) Vista puts it in the "blocked startup programs" list and the user needs to manually launch it. This is not acceptable for us. Is there any way to circumvent this problem And by the way, why is there no way for the user to say "I want this app to run every time I reboot so stop blocking it!" On a side note, I not ...Show All
