• Visual Studio anyone recommend a drawing package for help files?

  a documentation related question. can anyone recommend a good drawing package to produce diagrams for help files. I like the diagrams shown in the MSDN magazine articles, so what do their authors use Jason Jason, there are many good illustration products on the market. If you're looking to do something like a flow diagram a product like Visio works well. If you're willing to commit more time to learning a professional design application you can use products like Photoshop, Illustrator, or Freehand. I would recommend you take a look at each application to choose one to meet your needs. They are all very different and the learning curve can very steep. Depending upon your skill level you may choose so ...Show All

• SQL Server How to create simple insert trigger

• Game Technologies: DirectX, XNA, XACT, etc. Rendering To Textures in Beta2

  I used Texture2D's heavily with the usage RenderTarget, however in Beta 2 its like a whole new API. I understand that Surface no longer exists and RenderTarget/2D should be used. The problem is, the whole mentality is backwards compared to what im used to. From what I see I should create a RenderTarget2D and set that as a render target, then do rendertarget.GetTexture() if I want to set it. Thats fine. However, how do I copy between render targets There is no StretchRect or equivelent function I can see, which I used alot before. Surely I dont have to go about getting a texture, setting it, creating a 'copy' effect, setting a new render target, resolving the new render target just to copy from one to another Is there no alte ...Show All

• SQL Server SQL Database connection set up in Global.asax.vb for multiple users

  We have an application where users log in and set up a ConnectionString based on the login-info. As to now, we have used Application.Contents("conn") = (strConnectionString) in Global.asax.vb (Application_Start section) and then in the in the webforms we use Dim con As New SqlClient.SqlConnection con = New SqlClient.SqlConnection(Application("conn")) con.Open() ...... ...... con.close() (Each user has their own sql database that they connect to using the same scripts.) The question is: When many users are logged on at the same time, will the use of Application.Contents be a safe way to connect to each users own database or is there a possibility that users suddenly will try to establish a connection to a databa ...Show All

• .NET Development Updating Adds the same record to all rows in the Database instead of just one?

  Hello. I'm trying to update a single record in a database to add new data, but when I hit my update button and the event runs, it adds that record to ever record in the database overwriting the current data in the database. I'm not sure how to work around this problem. Any help would be greatly appreciated. Thank you. But if there's nothing in the record to compare then how do I use the where clause What I'm trying to do is add the record then save it to the database. So when I click my add button it adds a blank record. Then I entred the data and hit the update button to save that data to the database. I'm not sure how to use where when the new record is blank. ...Show All

• Smart Device Development Custom Control doesn't invalidate original drawing area when resized

  Hello, I'm having a problem anchoring and resizing custom controls on Windows CE 5.0. For testing purposes I created a simple custom control that overrides OnPaint and draws a border. The issue is that when I resize the control, either programmatically or by using anchoring, the original region of the control isn't updated. If the control is docked, the entire drawing region updates correctly. Does anyone know why this is happening I'm using CF 2.0 SP1. Chris That did the trick! I'm still curious why resizing a custom control at runtime doesn't invalidate it automatically. It does force a call to OnPaint, so what extra actions are taken by calling Invalidate Thanks for the help. Chris ...Show All

• Visual Studio Express Editions partial classes feature

  May I know how to turn off the partial class feature in Visual Studio 2005 (for express, and proffesional edition). Your avuable feedback is much appreciated. Thanks. IT is becuase MSBee is not support partial class feature in VS 2005. I failed to compile the program into .NET 1.1 version with MSBee. By the way, partial class is great while it seperate the designer code for us, but it do make some disadvantages too.

• SQL Server placing norms on a bar chart

  Maybe someone can help. I'd like to do one of two things, depending on which is actually possible: Place one chart on top of another so that, in addition to having a simple bar chart, I can also have a way of tracking c omparison data on the same chart. (My preference is a line chart with diamond markers on top of a bar chart.) Within one chart, have one of the series be a different chart type. Once series could be a bar and the next could be a line with diamond markers. The catch is the diamonds would have to be placed right on top of their corresponding bars. These are both things that I've been able to do in Excel, but am finding out that I've taken for granted just how versatile Excel is. Thanks in advance! Krdjis ...Show All

• SQL Server Drop down parameter list not showing

  I have a report which uses the selection from Parameter A to populate the choices in Parameter B. At the moment Parameter B only has 1 choice (more to be set up later) and 2 things happen: a) The text for the Parameter B choice is too long for the drop-down box generated b) When I try to select from the Parameter B box the drop down does not show the text, only a left/right slider bar.  I have to click between the slider bar & the drop-down box and then click away for the selection to be made. Why does this happen and how can I increase the width of the drop-down box.   ...Show All
