• SQL Server Analysis Services 2000/Excel 2003 and Drill through

  Has anyone got this to work in Excel 2003 Using Analysis Server itself I can use drill through - but whatever I do with Excel 2003 I can't get it to work. Thanks Hello. If you try to dubbel click on a cell in Excel 2003 thats is part of a pivot table area connected to AS 2000/AS2005 you will get a clear message that nothing will happens. If you use a Pivot table in Excel against a relational data source , you will get drill-through to the records thats is part of that pivot table. Conclusion,like Deepak already told you, it is not supported in Excel 2003 pivot tables. If you are using Report Builder in, RS 2005, you will get drillthrough as a feature. No lines of code required. Try the E ...Show All

• .NET Development Connection string for a local visual sql databases (*.mdf)

  Previously I've used access databases for different application which I create in Visual Basic (Visual Studio 2005). This time I need just a small db with one table (at this point), and I noticed the 'SQL database' (An empty SQL database for local data) at the project-> add new item option in Visual Studio. I created the database, and added a table. Both the database and the table itself can be viewed from the 'server explorer' window under 'data connections'. Everything is great up to this point. But how do I connect from my application to this database I guess there's no real SQL server running. I tried to create the connection string using a new.udl file, but it seems that none of the OLE connections can be used towards the mdf fi ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. End users shouldn't have to rewrite XNA math functions in order to improve performance.

  The overhead of passing a 64 byte Matrix by value is significant. Most especially when you are comparing two matrices for equivalency (==), or performing a Vector*Matrix multiplication (Vector3.Transform(Matrix)). The following matrix comparison function performs 5-10 times better than your built in == comparison. If the matrices are equal, then it is about 5 times faster. If they are unequal then it fails fast, and is about 10 times faster. public static bool Equals(ref Matrix a, ref Matrix b) { // i check the diagonal first for quick fails return a.M11 == b.M11 && a.M22 == b.M22 && a.M33 == b.M33 && a.M44 == b.M44 && a.M12 == b.M12 && a.M13 == b.M13 && a.M1 ...Show All

• Visual Studio 2008 (Pre-release) How do I open legacy structured storage files with IO.Package?

  We have some structured storage files that we want to be able to access with managed code. I am trying to avoid the PInvoke and/or Interop - and came across the IO.Packaging with the internal compound file stuff already done. I tried to use it but it defaults to xml package - and so I error - and I am wondering if it is possible and if someone has a sample of how to use these API's to open and read any compound file Thanks So if I understand Structured Storage correctly, the term "Structured Storage" is used for the native OLE32 API's which would require PInvoke and used the older StgOpenStorage calls and properties were all just stream read etc. The term "Compound File" ...Show All

• Windows Live Developer Forums Dashboard control

  Hi, How can I specify the dashboard position on the map In V2 there was an object parameter in MapControl() constructor. Using this object parameter I was able to specify where I want to place the dashboard. Is there something similar in V3 I tried playing with .Compass and .Zoombar styles but they move only compass and zoom bar respectively - the dashboard (light blue semitransparent box) remains in upper left corner of the map. Thank you, olley. I'll pass the request on to the team. In the meanwhile, you can do what many others are doing right now: create your own control (in a DIV, for example), and then use the VEMap.AddControl() method to add it to the map wherever you want.
