• Game Technologies: DirectX, XNA, XACT, etc. Sprite Doesn't Animate

  Alrighty, here we go again with another problem. I used to use a simple sprite sheet, but in recent days I have found I need to add some more functionality. My previous spritesheet class would load a sheet which had all frames have the same height and width. They were laid out horizontally, and the height and width were hardcoded. It worked, but I wanted to make a sprite sheet loader that could load and animate any sprite sheet, provided there was an XML document to explain where to look on the sheet. Thus, the actual frames can be anywhere on the sheet, in any order, just so long as the XML file is correct. So, I wrote that class. Now, come time to test it, the animation part of it doesn't work. Hard coding a frame to use shows that ...Show All

• Software Development for Windows Vista Workflow properties when debugging

  Hi, I am debugging a workflow winform application in Visual Studio, and was expecting to be able to monitor the values of workflow properties as I step through. This does not seem to be the case though. Does anyone know if this is by design or not Thanks and regards, /Valur If you workflows are in a workflow library you need to set it as the startup project in order to invoke the workflow debugger. On the project properties for your workflow project, set the startup to start the debug build of your winform exe. Matt ...Show All

• Windows Forms Add Serial Number column DataGrid 1.1

  Hi! I am using the DataGrid control in framework 1.1. What i need to do is add an additional column in the DataGrid which display the serial number for each row. This column(field) has no relation or value in the table i will bind the gird to, but will only be used for display puposes.

They dont however solve my problem. Is there a simpler way of doing this Any help would be appreciated. thanks, Rohan (plonk) i was adding the column after filling the dataset, no wonder it wasnt showing up. ...Show All

• SQL Server Need help to build the MDX query please?

  I need help on how to do this in MDX query. I have an OLAP cube with the following structure as an example Measures: M Dimension A: Attritute 1, Attritute 2, Attritute 3 Dimension B: Attritute 4, Attritute 5 (date/time) Dimension C: Attritute 6, Attritute 7 I need the dataset with all the attritutes and measures of this cube for the Reporting Services.

So you would need to create the controls, add them to a container and position them yourself. ...Show All

• SQL Server Matrix SSAS dimension/hierarchy order problem

  I have a have a relatively simple SSAS cube that I'm trying to display in a matrix but the order of the data is not correct. The rows of the matrix are a time hierarchy and the query designer produces the correct MDX and when I run the MDX in the data tab, the order is correct. However in the report preview tab, the order is incorrect. Specifically, the time hierarchy looks like this Year-Month-FullDate . The report is ordering the Months like this 1,10,11,12,2,3,4,5,6,7,8,9. I ran the MDX query in Sql Studio and the order is correct, and I used Excel to consume the same cube and it produces the correct order. The report is somehow treating the Month like character data instead of numeric, how do I fix this ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XACT - System.TypeInitializationException on start-up

  Anyone else seen this problem starting up XACT It worked in the past but I haven't used it for a few weeks. In the interim, I've installed the Vista SDK, .NET Framework 3.0, WF and WCF extensions for Visual Studio etc. I've uninstalled all these components and reinstalled GSE and Visual Studio Express but still get the same exception on start-up. In the debugger, I see Additional Information: System.Net.Dns threw an exception. I built a quick program to check I could use this class and it worked OK. I'm going to post a duplicate of this question on the XACT forum. Help ! Cheers.
