• Windows Forms Repopulate Combobox from second form

  Hi, I've got 2 windows forms (vb.net). The 1st form contains a combobox which is populated by a tablecolumn from a SQL Server database. On a 2nd form I can add items to this particular table. The second form is opened from the first form. When data is saved on the 2nd form, I call a public sub on the 1st form to repopulate the combobox on the 1st form: 2nd form: Private Sub btn_save_Click( ByVal sender As System.Object, ByVal e ...Show All

• Visual C++ non stopping compile?

  Hey, My Visual Studio C++ worked once well. But after I used it to do a project with Visual Parse, it does not work well. It compiles and compiles without stop. And I can not stop this process with the STOP-BUILD-Button. I must use Task-Manager to kill it. I think, I had changed some settings, but I can not remember now. I really don't know why, I can not even do a simple "HelloWorld" programm. Thanks a lot if you can give me som ...Show All

• Visual C# Business Object Sorting

  I have some custom business objects and need to implement some sorting logic. The sort requirement that I have requires the ability to sort on multiple columns as well. I am sure I am not the first that needs to do this, but so far I have not been able to find anything on the web that doesn't rely on a DB to do the sorting. That is not an option for me, so I need to implement this my self. Thanks for any help Kevin ...Show All

• Visual Basic TableAdapter update unchanged record cause Concurrency Violation

  I found that concurrency violation would occur if updating the database using table adapter when the actual record does not have any change. Seems like my DataGridView marked the row dirty. TableAdapter.Update would result in concurrency violation because zero record was modified. Seems like TableAdapter did not verify there are actual changes in the record before sending the update command. Bug It may be si ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotating around mesh center

  Hi, I have a little Mesh contained in a .x file. I then load the mesh into the file and try to rotate it (I'm using the EmptyProject solution provider with DX February 2006). My problem is that the Mesh doesn't rotate around the center of the mesh but around it's base. I was searching through the internet and I found this solution: device.Transform.World = Matrix.Translation(x,y,z) * Matrix.RotationX(angle); where x,y,z represent the center o ...Show All

• Windows Forms Filtering Parent row values based upon existing child value

  Hello everyone, here's my situation: I have two tables: PURCHASE and PURCHASE_LINE with a one to many relationship between PURCHASE and PURCHASE_LINE. I also have two data grids--one for each table. Both datagrids are bound to the same DataViewManager.

I tried doing this ...Show All

• SQL Server @@servername returns NULL value

  I have a SQL 2005 clustered server which is returning a Null value for @@servername. I find the server entry in sysservers.

So I am struck in a ...Show All

• .NET Development Datasets aren't finalized after leaving the scope

  Hi, we discovered a strange behaviour concerning garbage collection of datasets. Because our application needs a tremendous amount of memory and constantly allocates more and more of it we are counting the instances of our objects in memory. Thus we able to determinate if an object is finalized by the garbage collection. Basically most of our objects contain these code snippets in the "new" and "finalize" methods: Public Sub Ne ...Show All

• Windows Forms ComboBox Binding with a Blank Selected Index Initially???

  I'm making a search engine windows app that contains ComboBoxes that are bound to my SQL Server database. It would be so much better that once my ComboBox is bound that I could have no item selected (so a blank) incase they don't want to include that in their search but I can't seem to do that without putting in a blank record in my database and that seem soooooo wrong. The only answer I can think of is maybe populate an RA with the data leav ...Show All
