• Visual Studio 2008 (Pre-release) creating complex lookless controls

  Hey, What would be the best practice for collecting events from the template controls for a lookless custom control. Say I have 3 text areas on the custom control whose text is bound to some properties. That part is easy enough to do, but say I want to know if any of these areas have lost focus, and which one lost the focus Since these controls that are holding the text are defined in the template I don't have an easy way of discriminating between them. I can handle previewlostfocus or whichever, but to determine which was the control that lost fous means to me I'm left with the rather unsatisfactory solution of relying that they have some identifier in their control name, or something of that nature. Is there any way of rerouting an even ...Show All

• Visual C++ worker thread slowed by MFC UI interactions

  I create a SDI MFC program in which there is a worker thread to render a 3D scene. I found the rendering speed will be interupted and slowed by some UI interactions, e.g., moving the window by drag the window title, mouse move on some toolbar's buttons. However the program implemented by C win32 API has little performence decrease under the same condition.  Could you give some suggestion Thanks. I haven't manually invalidated the view or coustomized its ondraw function. I just create a 3D engine renderer(Ogre 3D engine) in the worker thread and give the HWND of the view to it. Then call the 3D engine's method "renderOneFrame" in the loop of the worker thread. I guess the engine do the ...Show All

• SQL Server Database roles

  I am not sure if this is the right place for this question or not but here it goes... I want to add a new user to the database with read-only rights. I know public is selected by default and can not be changed. I also added the user to db_datareader and db_denydatawriter. But just as I was about to save I noticed Read Only. I have done some searching but have not found anything about this role. I assume it does just what it says but I am confused as to why it would be there when I can set the other settings I just did. Is there any benefit to using this role instead of the ones I chose Should I add this role in addition to the two I have already picked Any help is greatly appreciated. thank you, Kevin ...Show All

• Visual Studio Tools for Office Setting the AppDomain ApplicationName

  Hi, I'm developing a Outlook add-in that needs to load dynamically generated assemblies. I've hit a snag when trying to set the AppDomainSetup.DynamicBase property as this requires there to be an ApplicationName for the AppDomain. It seems that the VSTO runtime does not specify the ApplicationName when it creates the AppDomain for my add-in. Does anybody know whether it's possible to "coerce" vstor to specify an ApplicationName when it creates the AppDomain Thanks, Dave Gardner Hi Dave. The only control that VSTO supports for configuring the AppDomain via a .dll.config file using the usual AppDomain config-file schema . Unfortunately, to my knowledge, the ApplicationName is no ...Show All

• Visual Basic Image Transparency. Set a level of transparency then to make an opaque image like in Vista.

  I'm in over my head on this topic, but thought I'd give it a try if anyone could help me out. Now, before you say "just set the property to transparent etc.," that's not my issue. I can do that. My problem is, when the image does in fact go transparent, the background shows up in place of the transparent area. I don't want to see the background, but rather the potential picture that could be behind it. Obviously if there is no picturebox behind it then it would default to the background though. Any help would be appreciated. I've tried many things and none have worked for me. I've been using .gif's but could switch to .png or other formats if needed, just let me know how I can achieve this. ...Show All
