• Visual Studio Express Editions How can I prevent the first picture from disappearing?

  I have a picturbox with a background picture. I add a picture with a transparent background. No problem, the background remains. I add a second picture with a transparent background. The first picture disappears, happily the background does remain. How can I prevent the first picture from disappearing I am not sure what you are doing. If you have a PictureBox and set the BackgroundImage and then the Image properties you can not set the Image property again to add another image to it. It will replace the first image you set.

• Visual Studio 2008 (Pre-release) Passthrough of ASP.NET identity to WCF service layer.

  I have a WCF service hosted in IIS, and an ASP.NET application that consumes it. I need to provide user-based security at both the application and service level, and so I'm trying to propogate the ASP.NET user through to the WCF service. I need to be able to do this for both Windows and Web-Forms authenticated users, but I figured Windows would be the easier win to start with. My binding is currently wsHttpBinding, and I've tried both Transport and Message security using Windows credentials. I've also tried using [OperationBehavior(Impersonation=ImpersonationOption.Required)] on my service to no avail. All I ever see is my IIS user bei ...Show All

• Smart Device Development CBitmapButton?

  Hi, Today when i made an application using CBitmapButton i met this notification: uses undefined class 'CBitmapButton' Visual studio 2005 for pocket pc 2005 isn't supported this class. What is the purpose of it JT   I am not sure what you are asking for but I took your code and implemented it and it worked for me.  I had to switch the CButton over to owner draw but other then that it worked great. On a side note; when I did my own CImgBtn I used one Resource ID with four images within it and used StretchBlt to only draw the btn I wanted.  This cleans up the code a little and allows for one bitmap to be loaded instead ...Show All
