• Windows Forms add 2 DataTables into 1 DataGrid

  hi, I have 2 dataadapters that fills 2 datatables i want to show them both in 1 datagrid How do i do it I think detail steps to combine two tables depend on the logic how you want to combine them. If you just want to create a new table with all columns in those original two tables, use following code for example DataTable dt = new DataTable(); foreach (DataColumn column in northwindDataSet.Customers.Columns) dt.Columns.Add( new DataColumn(column.ColumnName,column.DataType,column.Expression)); foreach (DataColumn column in northwindDataSet.Employees.Columns) { if (dt.Columns.Contains(column.ColumnName)) continue ; dt.Columns.Add( new DataColum ...Show All

• Visual Basic Adding Controls Dynamically

  Hello, I am going to try and explain this to the best of my ability. Within a form I am going to be using probably (open to suggestions) a TableLayoutPanel to split the header section and the diffrent controls. The unquie part about it is, whenever the header is clicked another whole header and the diffrent controls are added. So for example this is what it looks like when the form initially loads: -------------------------------------------------------------------------- Header - Header - Header - Header - Header - Header - Header -------------------------------------------------------------------------- 26 Controls within a panel -------------------------------------------------------------------------- After the form is loaded an ...Show All

• Windows Forms Printing scrollable ListView with PrintForm component

  I have been trying to use the new PrintForm component in VS2005 to print forms in my VB.NET Windows application. I am running into two problems: 1) I can not print the content of a scrollable ListView. Let's say I have a ListView control on the form I want to print. I print the form using the following code: Me .Main_PrintForm.PrintAction = Printing.PrintAction.PrintToPrinter Me .Main_PrintForm.Print( Me .ActiveMdiChild, PowerPacks.Printing.PrintForm.PrintOption.FullWindow) which does print the form, but the content of the ListView is cut off to only the visible part of it. I want to print all the elements of the ListView including the ones that are not visible to the user that they would have to scroll down in the ListView ...Show All

• SQL Server Errors on install of SQL Svr 2005 Enterprise

  Greetings, I have attempted a full install of 2005 Ent on our W2k3 Enterprise server.

• Audio and Video Development R

  Hi. I'm sending "dummy sample" when there are no data to send from source. butRequestSample() come buck so quickly and keeps spining until data are ready. It's really waste of CPU power. What should I do to stop this I'm trying to build something like a LiveTV player. Thanks. Kasumi. I'm guessing that you have an MFT downstream of the Media Source that interprets these dummy samples as "no data". If you give this "no data" sample a duration, then your MFT can just produce that duration's worth of silence (audio) or repeated frames (video) and return MF_E_TRANSFORM_NEED_MORE_INPUT from ProcessOutput only when those have been exhausted. This will keep MF f ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is there any built librarys/function for collision detection?

  I was just wondering if there's any sort collision detection build in to XNA If so what can we expect We provide a number of bounding volumes with intersection and containment checks. This would give you simple collision detection. We do not provide any sort of complex collision detection or physics simulation (collision or response). Paul ...Show All
