• Visual Basic Accessing VB component property methods from C# application

  Hello Can someone help me for the below proble, I am working on a task of converting one vb6 application in .Net. Current vb6 application is using one vb dll provided by third party. I have written a code in C# and added the third party dll (developed in vb6) in the reference. The strange problem I am facing is that I am able to access all the properties of vb6 dll but not the methods of the property.One thing I do not know is whether the property datatype is collection or any other datatype. For example : TestClient.Client objClient = new TestClient.Client(); I am able access the "GenericBO' property of the objClient but not the "Item" method of the "GenericBO' property. In current VB6 the sam ...Show All

• Visual Studio 2008 (Pre-release) Wizard question?

    Hey all... two part question... I'll name the SQL server db and the SQLCE DB clientdb  What is the fastest way to create a SQL Compact Edition db from an existing SQL Server Database and Can I sync only the tables of this clientdb.sdf with the server   No tombstone tables for this example just a straight table sync. Any help would be greatly appreciated. Thanks, BillB SQL CE does not support bulk copy (BCP) thus you are left with doing it manually (inserting row by row) or using sync. If you chose to use sync services, you can use the configure each table with snapshot direction on the agent. On the server side, your table sync adapter need to have the SelectIncrementalInsertsCommand only (i.e. ...Show All

• Visual Studio 2008 (Pre-release) question about PrintVisual?

  Hi, I am using PrintVisual() to print out a xaml visual element. The problem I have is how to show a busy signal (for example an animation) to the end user while the xaml element is printed. I try to start a busy animation right before calling PrintVisual but it didn't work. It seems PrintVisual is blocking all painting event. Any suggestion to work around the problem thanks chong Hi Keith, I've gotten quite deep into a problem where I could make use of such an example. I've scoured the docs and can't find a good, complete example of something meaningful being done on a secondary thread, in particular, something that would require the use of VisualTarget/HostVisual classes.

• Smart Device Development How to center a dialog box

  Hello, Looking at some of the msdn code I found the snippet below that I am trying to use for a customize dialog box. MSDN states this is available on compact 2.0 but I get the message stating it's not declared. Any help would be appreciated. John Dim form1 as new form() form1.StartPosition = FormStartPosition.CenterScreen I may be looking at a different page than you... however the StartPosition MSDN page does not have any mention of CF2.

• Game Technologies: DirectX, XNA, XACT, etc. Question about location and number of main game objects

  Ok so I'm still starting out with XNA, so apologies if this sounds like a strange question. I'm still getting the hang of the architeture of XNA, and am having trouble working out the numbers and location in the heirarcy of certain important game objects. Im using a GameState style engine for my game, and refer to each "state" as a "screen" This is my current layout... GraphicsDevice - One in main game class, passed through constructors to relevent functions ContentManager - One per "screen", made sense as if a screen unloads then all its content should unload too ( ) SpriteBatch - Currently one for each low level game object (eg, Sprite object, UIElement object) however i think this should be higher up and pa ...Show All

• Visual Studio Team System Status of build in a team project

  How can i get the status of a build running in a team project. In C# or from the command line.   Also what event is fired after every chanege of build status (eg. Initialization, Getting sources, Testing etc.). thanks You can check on the build status of a running build in the UI. But you can not get the status of a running build from the command line. There are BuildStatusChangeEvent and BuildCompletionEvent. Note that the BuildStatusChangeEvent is fired only when there is a change in Build Quality and not for the build steps (Initialization, Getting sources, etc.). You can set up notification for these 2 events through Project Alerts. Swaha ...Show All

• SQL Server Subscriptions invalid after SP applied

  Hello, I finished applying SP 1 to sql2k5. Under the replication monitor all of the subscriptions now look like [].databasename when they were originally [subscriber1].databasename. Under Mgmt Studio I see the subscriptions correctly. When I try and replicate I get the message "The subscription to publication 'pub_databasename has expired or does not exist." I have tried to reinitialize the subscriptions but it doesn't work. Is there a way to solve this without have to drop the subscriptions and add them again as I do not want to lose the changes that were made on the subscriptions. We are using merge replication.

• Visual Studio Express Editions Capturing form dimensions

  Hi all, One of the things I'm trying to do with my current project is to preserve the most recent dimensions (x, y, w, h) of all the forms upon user exit. And then, when the user runs the program again, the settings are restored. Currently, I'm using the StreamWriter to send the form dimensions to a text file. This seems to work fine for my "main" window ("Me." below), but for some reason my other form ("OutputConsole") only holds the orginial values for the form when it was instanced. In other words, the values don't seem to be changing when I resize and reposition the window. What ends up happening is, the main form settings are captured, but the "OutputConsole" is only capturing the initial ...Show All
