• Smart Device Development Questions on using RIL on Smartphones

  Hello, I am new to developing on the Windows Mobile platform and have just started writing an app for Smartphones running Windows Mobile 5.0. My first task is to get the cell tower ID that the phone is currently registered to. I searched MSDN and other discussion forums and found that I can use the RIL functions to get this information. My first confusion was wether RIL was even supported on Windows Mobile 5.0 since MSDN includes RIL and Cellcore under 'Windows CE Embedded 6.0'. However, judging by some messages on other forums, RIL does seem to be available on Mobile 5.0. So far, so good. I tried to write a simple app using RIL functions but couldn't build it. I can't find any RIL-related files in my SDK install. After some more searchi ...Show All

  Dear Members, In the documentation of WPF in : http://windowssdk.msdn.microsoft.com/en-us/library/ms743714.aspx said that I have to add System.STAThread attribute.

• Game Technologies: DirectX, XNA, XACT, etc. Grid using triangle strip?

  Hello, sorry if this is a stupid question, but I was wondering is it possible to draw grid of triangles using triangle strip instead of triangle list I guess you can do this by turning culling mode off, but I was wondering is it possible to do with culling on Thanks, ErnisJ Whenever in doubt: just use an indexed triangle list. The only real use for TriangleFan, or TriangleStrip is to decrease how many vertices are sent and processed. When you use an IndexBuffer the amount of vertices is already decreased to the minimum, so those other primitive types become worthless. ...Show All

• Windows Forms Disable automatic exception handling in DataGrid control

  Hi, I have a DataGrid control (the project was migrated from .NET Fx 1.1, and we don't use DataGridView). When the DataGrid commits a row to the data bound DataSet, if a constraint is violated, the DataSet throws an exception, and the DataGrid automatically shows a MessageBox. I would like to change that MessageBox but, if I catch the exception, the DataGrid doesn't roll changes back. Is there a way to ask DataGrid to handle exceptions, revert changes, and refrain from showing a MessageBox Thanks in advance Hi Ken, Thanks for your answer. The exception I'm trying to catch is a row-level validation exception, i.e., it is fired when the DataGrid calls EndUpdate on the DataRow and the ...Show All
