• Visual Basic setting default favlue of a field in MS access

  Hi, I am having trouble in this specific situation. I have a form and I need the drop-down box value to set the default value property of another table. I have seen this done before, I just can't remember how it was done. Any help would be appreciated Thanks, Christopher Custer Christopher.Custer@gmail.com use the connection objects getschema method to return a datatable with schema info from the table you need to access...Use the dropdowns change event to update the datatable and write it back to the db...

• SQL Server Teradata data extension question

  I recently installed the Teradata .NET data provider and I am trying to use named parameters and multi-value parameters in my SQL.   I am finding information on this topic hard to come by.   In order to get parameters to work do I need to write my own Teradata data extension from scratch, expand an existing data extension to work with Teradata, or can I simple edit my .config files to point to a generic extension wrapper already existing   Thanks! You need to implement a custom data extension. In order to have named parameters working, you need to implement your own commandtext parsing algorithm that detects the parameter names. Since the Teradata .NET data p ...Show All

• Visual Basic Accessing Windows Forms Class

  I have found the following problem: 1. I have a Form1, which has a non-private constant named TestConstant. 2. I have a Form2, which on Load will retrieve the constant from Form1, using the syntax of Form1.TestConstant. 3. The compiler generates a warning about accessing constant via an instance. Most likely is caused by the default instance of Windows Forms. Any way to remove this warning (by accessing the class not the instance) Hi, have you considered something like using read-only shared variable instead of constant Public Shared ReadOnly TestConstant As String = "TestConstant" Andrej ...Show All

• .NET Development Performance counters

  Hi, I am trying to figure out how the performance counters work and I'm having some difficulties understanding some of the types. I have a very simple application that creates a counter instance and then I use perfmon.exe to see the values generated by my program. I successfully tried the AverageCount64 type, using the AverageBase. Although I continuously increment the counter I see the average in perfmon, as expected. When I try RateOfCountsPerSecond32 for instance, I increment the counter in the same way, but instead of seeing the rate per second in perfmon, I see the raw value of the counter being displayed. The curve keeps going up as long as my applications is running. Now since RateOfCountsPerSecond32 doesn't have a base typ ...Show All

• Visual Studio Using a non-standard paper format using printToPrinter in CR for VS2005

  Hi. I'm working on a asp.net Intranet application, and I must print label on a network label printer. There's is no preview, the print job is sent by the server directly to the printer. So far I can print, but I have to made my label format the default format in the printer driver, and that's bugging me. The label are 4in by 2in which is not one of the predefined format in CrystalDecisions.Shared.PaperSize. I want to be able to define the paperSize before calling PrintToPrinter. The CR support web site tell this : ...It is possible to design a report in the Crystal Reports Designer specifying a custom paper size.

• Visual Studio Weird VS error when compiling pacakge "devenv.com" exited with code -1."

  I recently opened a project to begin working on it after not having touched it for a few weeks. This project is a managed package in C# running on Vista (latest RC). All the sudden, I'm getting a weird error related to the VsSDK.targets tasks that run at the end of compilation. This is the error I get: c:\Program Files\Visual Studio 2005 SDK\2006.09\VisualStudioIntegration\Tools\Build\Microsoft.VsSDK.targets(227,5): error MSB6006: "devenv.com" exited with code -1.

• Game Technologies: DirectX, XNA, XACT, etc. SpaceWars SceneItem implemenation

  I've been going through the code files for the SpaceWars sample game. I was somewhat confused by the SceneItem class, because it inherits from List<SceneItem>. This throws me off because I wouldn't expect a "scene item" "is a" list of scene items. Does anyone have any insight into the logic here In a minimal scene graph, you always set the position relative to the parent, so if your parent rotates, you will revolve around the parent. Think of a hand holding a sword; when the elbow is moved, the sword hilt rotates around the elbow. In slightly fuller-featured scene graphs, you can set (and get) the position either relative to the parent, or relative to the world. When setting the p ...Show All

• Visual Studio 2008 (Pre-release) Orcas Jan CTP does not have the May 2006 LINQ CTP functionality, March CTP should!

  I have seen a few qestions pop up about GetTable() not being public and a few other LINQ to SQL (DLinq) capabilities not being in the Orcas Jan CTP . The Orcas Jan CTP is an interim build which does not contain all the May 2006 LINQ CTP features. Those features are planned for the Orcas March 2007 CTP. For those who are curious about the process, here is how it works: - Each feature, whether shown before in a preview like LINQ preview or not, has to pass a bunch of quality gates. This is an interesting but intense process that takes a while. - As each feature passes the quality gates, it makes its way to a common branch which eventually builds the entire product with several dozen components. - Orcas CTPs are like trains with s ...Show All
