Visual Basic Displaying Windows screen while program is not stopped.
I have a vb.net program (v2003) that needs to display a windows screen and pause x number of seconds before refreshing it again. However, I cannot get the screen to display unless my program stops. I have tried the Timer class as well as my own pause, but the screen will not display until I stop, not pause, the program. Any help please Thanks, Donald Not sure if I understand the problem, but try throwing in some code like below, at the point you want the 'window' updated: Me .Invalidate() ' or ControlNameWhatever.Invalidate Application.DoEvents() ...Show All
SQL Server use exists in join
Hello, Can i somehow use exists() function in JOIN ON clause for example SELECT * FROM Table1 INNER JOIN ON Table1.Col1 = Table2.Col1 AND EXISTS(SELECT * FROM Table2 WHERE Table2.Col2 = Table1.Col2) It doesn't work on my query. So, basically i want to do an inner join so that Table1 gets filtered. Then I make sure that every entry in the filtered Table1 has an existing related entry in Table2. i need to do exists because there could be more than one relation in Table2 for each entry in Table1, but i don't want multiple repetition of entries in the filtered Table1. (Not sure if i am making it clear!) I need distict selection, but i am adding NEWID() at the beginning of my query so distinct doesn't work for the rows. with my current query, i ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Draw() called before Update()
I noticed Game.Draw() is being called before Game.Update(), which doesn't (seem to) make sense. Is there any suggested way of dealing with this If Update() is supposed to, umm, update the state of the application to a certain local time, before the first Draw() there is no state ready to be painted to speak of. Well, the forum kind of does have a known issues sticky. It's jut over at Connect. You can review all the previously reported issues and suggestions there. No real point in having them in two places, keeps it simple that way. Also, I'm sure the FAQ will expand, the team might just be a little busy at the moment for keeping it updated and improving upon it. That's where the community comes in ...Show All

Visual C# Number Guessing Game
Hi, I am new to C#. I am originally a Visual Basic programmer and was wanting some help on a guessing game of my own. I was wanting to know how I would use the random function in my program to generate integer between 1 and 100. This program could either be a console app. or a Win app. However, I have no experience in Win app's in C#. Any help will be appreciated. pretty simple! use the Random class and give it a min and max value to generate a number with using the Next() method: Random theRandomGen = new Random(); int numberChosen = theRandomGen.Next( min, max ); in your case: Random theRandomGen = new Random(); int numberChosen = theRandomGen.Next( 1, 100 ); this will work for ...Show All

Visual Studio 2008 (Pre-release) Vista Beta 2 IIS7 setup
I've just upgraded to the new Vista Beta 2 build 5384 and am unable to get any of the WCF samples provided with the SDK to run. I'm pretty sure it's just an IIS7 setup issue. From reading around i've seen a few sites recommending that i add a MIME type mapping for the .svc file... but i cant' work out how to do that. This ( http://www.iis.net/default.aspx tabid=2&subtabid=25&i=1032) suggests that there should be a MIME Types item in the list of things i can configure for the default web site in inetmgr ... but it's not there Here's what i have done so far. Installed... 1. Vista 2. IIS - added the windows feature 3. Windows SDK 4. WCF (en_windows_communication_foundation_beta2_x86) 5. Visual Studio 2005 6. vse ...Show All
Internet Explorer Development IE Interop
Hi, I've been trying to write a Custom Download Manager for IE using C#. I've found some information here: http://msdn.microsoft.com/library/default.asp url=/workshop/browser/ext/overview/downloadmgr.asp , but I can't figure out what CLSID I should refer to my managed library as, or if I need to register it or something. I don't have any experience in working with COM, so using a hybrid solution could be difficult for me. All suggestions are welcome. Reuben. Sorry if I was unclear, but I'm using C#, and all my code is managed, so there is no COM component for me to register. I registered my managed DLL (with the ComVisibleAttribute), and I know that IE is trying to load my library, be ...Show All
Software Development for Windows Vista Adding Custom ExternalDataExchangeService via web.config
Was really excited when I read the following in the "What's New" doc for the VS WF Extensions install.. 10.1.1.2 Host and Services Migration and Code Changes The host won’t need to manually add services to the ExternalDataExchangeService. All of this can be done via the Application or Web configuration files. So... while leaving the existing ExternalDataExchangeService line in my web.config file, I added the following line (eager with anticipation... :D) < add type= "custom.assembly.MyCustomServiceType, custom.assembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> But alas, as soon as I removed the code I had been using to "manually" add my custom service and restarted the app ...Show All
