• SQL Server AMO: Enumerate Calculated Members?

  Hi, Apologies if I'm missing something obvious here. I'm trying to enumerate the calculated members in a cube using AMO (as part of programmatically building perspectives), however I can't see an easy way to do this. The collection of CalculationProperty objects on the cube's MdxScript object(s) would seem perfect (and indeed works for Adventure Works), but for my own hand-built cubes this collection is empty; CalculationProperty settings don't seem to be exposed anywhere in the BIDS UI so I assume they can only be set programmatically, which is of no particular use to me in the general case when operating on potentially manually-produced cubes. Aside from using CalculationProperty the only way I can see to do this within AMO would be to p ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. input strategy

  Is getting a input device state heavy Should I only do it once per tick and save the info to some global variables that the rest of the of the program can access. Or can I use GetState() everytime I need to check the state of a input device Its probably a good idea I also made an input state manager (InputStateTracker) so I only call GetState() on mouse and keyboard once per frame as I am also using an action mapping implementation where you can map the input to enums of actions, and it got out of hand with all the GetState() calls I had :P ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. really strange problem with pixel shader!

  I am implement a ambient occlusion, which throw several rays to check how many rays intersect with geometry. in my pixel shader I throw rays, if a ray intersects with any triangles, one variable will be increased by 1 and will be used afterward for shading. I initialize the variable ( iNumberOfIntersectedRays in my case)as 0, and increase it by one in the condition mensioned above. the problem is that when I debug the shader, sometime the variable is -1 or -2, and it just comes randomly. very strange. what possible mistake I have made. following is part of my code, anyone can help my out, thanks. float4 AO_PS( in float3 inColour : COLOR0, in float3 inPosition:COLOR1, in float3 inNormal : COLOR2, in float2 vPosition: VPOS ...Show All

• Visual C# What does THROW mean?

  I have C# and have been programming for two years. But, I still have NO IDEA what throw means! What does it mean it is generally used with the "new exception" meaning to throw back the exception to the caller, create an exception and "throw" it back to the caller of that method http://msdn2.microsoft.com/en-us/library/1ah5wsex.aspx should there not be a try catch block and you throw a new exception, you would get a JIT runtime exception when running the application. try it ;-) ...Show All

• Windows Forms Using data from gridview to pre-populate a field in a Fieldview Insert

  Ok I have 2 SqlDataConntions, 1 is for a users list, the other is for a list of items attached to the selected user. I use a multiview with 2 views to deal with this list of items. View 1 is a datalist control that displays the list View 2 is a Formview control that is only setup for insert mode. What I need to be able to do is when I add items with my Formview, I can draw one field ( the keyid of the selected item from the first SqlDataConntion) into my Formview so it populates a field on that Formview to link the data together. I'm sure it's somethign simple but I can't figure out how to do it. ...Show All

This Background Layer has a custom type converter called LayerConverter. The problem I am having is that when I edit the collection via the designer the collection property editor is wrong. The properties that I can see are under an expansion box called "Value", changing this value doesn't work it keeps reverting back. I have traced it to the fact that whatever calls the type converter calls ...Show All

• Windows Live Developer Forums Get Coordinates onclick

  I'm fairly new to javascript, and, as such, I have what I feel like should be a simple question. I want to get the coordinates (either pixel x, y or latitude, longitude will do) of where the user clicks on the map. I want to place push pins where they click, and, ultimately, I want to allow a connect the dots type drawing where the user simply clicks and a line is connected from where he previously clicked. I was hoping this could be raised as an event, but it doesn't look like it. Thanks in advance. Nice helper function -- I like the conversions. For the map events, I use something similar, attached to the two functions like this so that every time the map is moved the status bar receives an update: map.AttachEvent( "onendc ...Show All

• Windows Forms Disable New Row on DataGrid

  Is there any way to disable the ability to create a new row at the bottom of a datagrid The row marked as "*" appears automatically and I want to disable so I can programatically control inserting of new rows. Thanks If the new row is showing up, then your datasource is an IBindingList (a DataView if you are binding to a DataTable). You need to set the AllowNew property of the datasource to false. For example, if you are binding to the DataTable myDataTable, then set "myDataTable.DefaultView.AllowNew = false;". ...Show All

• Windows Forms How to choose the execution thread for a delegate?

  Hello. I wonder how to choose a specific execution thread for a delegate. With "simple" async delegate calls, we just know it will run on some thread of the thread pool, but not on which one. Control.Invoke(...) method allow to get the delegate running on the GUI thread of the control. The BackgroundWorker component matches it, I don't know how, to get back to the "main" thread (in opposition to the worker thread), whithout a reference to a control. Is there any way I can do something similar to the BackgroundWorker component, choosing the executing thread for a delegate without reference to a control Thanks... ;) The IDE debugger and the "Edit and Continue&q ...Show All
