• Visual C++ Changing Static properties.. Is this impossible?

  Hi there.. I have been trying for days now to change the property of visible on a static text control in my application to false during runtime. I have researched this and researched this, and even posted on Expert Exchange, but no one seems to know how to do this.... I'll post the answer I was given on EE.com, and hopefully someone here will know more about it. I have only been programming in C++ for a week now, so forgive me if this is a stupid question.... I have several static text controls setup in my application (DirectX pong game) to report various stats that assisted me in creating the game and diagnosing troubles that may arise setup in a console.rc resource in my project. These are displayed in a control panel beneath the ...Show All

• Windows Forms Multi thread

  Hi, I have a while loop which keeps showing words in a label on a Form. I can still do events with the Application.DoEvents(). But the while loop contains 2 thread.sleep(). Which makes it slowing down in handling events. Its getting stuck for 5 seconds in total. I thought i might solve this problem by using multi threads. Once the first thread starts which contains the while loop, it should start a second thead that contains the Application.DoEvents() and not slowing it down anymore. Can this be done like how i described it Or does anyone has a better solution I'm all ears, thanks in advance! sure well yes, since its in a while loop it will constantly go insane and act as if your app is not responding bu ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Poor XNA performance or my poor code... or normal?

  I've have created a simple scene that renders 8000 identical cubes. I know thats a lot of cubes, but I only get 4 FPS on a 2.0ghz dual core with a 7300 mobile graphics card at 640x480 with simply vertex shading and one directional light.

• Visual Studio 2008 (Pre-release) Possible bug in pagination? AND (() = ())

  I tried to make the simple project using DLinq and found this issue: var v = ( from blog in db.Blogs orderby blog.BlogID select new { BlogName = blog.BlogName, Login = blog. User .

• SQL Server Copy SQL Server 2005 DB to SQL Server Mobile - is it possible?

  I'm creating a prototype of a PDA app using CF.Net 2.0 and SQL Server Mobile for a prospective client and I've gone through and designed, built and populated a database using SQL Server 2005... and then realised where I really need it is on the PDA!

TIA for any help... there must be a way to do this but I'm quite new to SQL Server ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. get screen resolution & FullScreen

  How do I get screen resolution of the computer Because my program will be shared between many computers, I want the program to find the resolution of the computer on wich it is running. By example, on my computer at home, the program will return the value 1024 and the value 768 in order to make 1024 X 768. On my laptop, I will get 1920 and 1200. I want to get the width and the height separately, in two variables. With those values, I will be able to set automatically on each computer the window size as I want it.

If I ever decide to start the game in FullScreen (Make the wind ...Show All

• SQL Server online index rebuild and update statistics

  Hi .. Please advice whether i have to do update statistics along with Index rebuild (online /off line) Thanks in advance This depends on the traffic on your DB. IF its an OLTP/heavily used DB you might keep this for off peak use. Your Index scripts could be scripted to either update or do not update stats. You dont *have to* update stats. Its optional. But generally its good to keep updated stats. Again, depending on your Db size and usage, you can turn Auto Statistics ON or OFF. ...Show All

  I apologize if this question has been asked prveviously: I have created a simple dialog with a CStatic object as picture frame to show JPG image, however when I start the MFC program in different PCs it changes the rectangle size.
