  hi all, i'm building a auto complete combo box, problem is i have alot of items in my combo box. Is there anyway to search through the combo box without looping through the whole thing. Say if you're looking for the last item, you don't need to loop through from item 1 to the end Here's my code : Public Function PointToComboItem(ByVal cboComboBox As ComboBox, ByVal strValueSearch As String) As Boolean Dim i As Integer Dim currentIndex As Integer If cboComboBox.SelectedIndex < 0 Then currentIndex = 0 Else currentIndex = cboComboBox.SelectedIndex Try If Trim(strValueSearch) = "" Then Exit Function For i = 0 To cboComboBox.Items.Count - 1 cboComboBox.SelectedIndex = i If Left(Trim(c ...Show All

• Windows Forms How to total up a column in datagridview?

• Windows Forms GDI+

  when ever i use something like: System::Drawing::Pen ^pen= gcnew System::Drawing::Pen(System::Drawing::Color::Black, 100); grfx = System::Drawing::Graphics::FromHwnd( this ->Handle); grfx->DrawLine(pen, 1, 1, 1 ,20); Threading::Thread::Sleep(1000); grfx->Clear(System::Drawing::Color::White); it draws ok. but when ever i move the app offscreen the line that i just drawn, dissapears. how do i fix this thanks in advanced, Dan. You should ideally not use Graphics::FromHwnd, but should rather place your drawing code in the OnPaint override or the Paint event. These will pass you a PaintEventArgs that contains a graphics surface to draw to. You will also then not need the Thread::Sleep either. ...Show All

• .NET Development Yet another GC question

  I would be happy if someone will be able to answer the following question. recently I was investigating memory leaks & handles problem during my work. I have seen a very strange phenomenon: I have a class that exposes only static methods. on one of the methods I do the following things I create an start thread The ThreadStart delegate calls a method that call GC.Collect() & GC.WaitForPendingFinalizers(). Most of the time the new thread never finishes it's work because it gets stuck in GC.WaitForPendingFinalizers(). The only scenario that this thread is resumed is when I activate another GC collection from my program's console menu. The whole phenomenon doesn't happen if I make the following changes: I use gc ...Show All

• Software Development for Windows Vista WCF activities, in a Winform host application and state machine WF.

  Hello everybody. I've created a workflow template in which there host application is a Winform app. This application runs a workflow using thread donation technique (using ManualWorkflowSchedulerService). Now, I've created some custom activities: one of them is used for navigation between one form and another in host application. Well, I did an Execute method override and, instead of invoking externaldataservice contract method (like the job done by a CallExternalMethod activity), I called directly the winform application classes for changing forms. Is it correct or is better to call CallExternalMethod activity Another question: I would like to create some custom activities to perform WCF service invocations, like sendmessage, receivemess ...Show All

• SQL Server Reporting on a Cube -- Time Dimension Issue

  Hello, I have an Analysis Services Cube that I would like to report on. However, the Time Dimension currently only has four columns, Day of Month, Month(name) , Year, and DateKey (DateTime representation at midnight for every day). Thus when I drag the month attribute onto the report, it is sorted April - August - December - etc. instead of Jan - Feb - Mar. How do I fix this I remember reading something in the MSDN Library about it but I can't find it again now. Thomas Hmm, I haven't added any sorting, this is just drag-and-drop from the list of dimensions in the "Report Builder" tool for Reporting Services and in Visual Studio. So I haven't added any sorting, however in VS I can modify the User ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How do I protect my code when distributing it?

  Having read the FAQ. I noticed that in order to share your game creations (and lets face it, you can't get recognised without sharing your games), you need to send the other person the entire uncompiled game. This includes sourcecode, graphics, music, sound etc. etc. They then compile the code and download it to their xbox360 account and then only if they too are on the games creation program. My key worry here is that you send them everything you have just worked incredibly hard to create. Presumably they can then send this stuff on to whoever they please and god forbid, even sell it on! It strikes me that there isn't much incentive to distribute things this way. How is Microsoft going to prevent the above scenario Is there going to be a ...Show All
