• Windows Forms Bitmap Resources file error...

  Hi… In my MDI application I am using 3 threads…& in my resources folder I have added an bitmap image ( Green.bmp )…. From all three threads on certain conditions I am changing the image on form.

• Windows Forms change the font style of the tab page

  Hello All Is it possible to change the font style of the tab page when the tab controls _SelectedIndexChanged event occurs. My requirement is to change the font style of the selected tab page so it can be distingued among the other tab page fonts. I am using TabControl control /Thanks in Advance Prash You'll need owner draw to do this.

• Game Technologies: DirectX, XNA, XACT, etc. Trouble with color with 3D lines

  I just learned how to plot 3D lines - I mean actual 3D lines. The problem I hit is with their colors. I cannot quite control it - need advice what to read or in case I am missing an "obvious" declaration or something. I declare the line like: Verts = new CustomVertex . PositionColored [2]; Verts[0] = new CustomVertex . PositionColored (0, 0, -100, Color .Red.ToArgb()); Verts[1] = new CustomVertex . PositionColored (0, 0, +100, Color .Red.ToArgb()); Then I draw it like: device.DrawUserPrimitives( PrimitiveType .LineList, 1, Verts); I noticed that its color - you see up I set it to RED - varies depending on things I do not yet understand - like for example If I had defined a material for a ...Show All

• Software Development for Windows Vista change delay timeoutduration

  Hello guys, I have a state machine workflow, and to create a timer, I used a delay inside an event driven. Is there anyway to change timeoutduration of this delay to a new value, while the instance of the workflow is running, so the timer expires at that new time. I couldn't find any code samples for that. Any help would be greatly appreciated. It IS possible to change the duration during execution , however not with the out-of-the-box Delay-activity. My ConfigurableDelay-activity does exactly that. You can have it wake up every few days/week, independent of the configured duration. I used this functionality to fix a bug in the standard Delay-activity ( http://forums.microsoft.com/MSDN/ShowP ...Show All

• .NET Development .Net 2005 app fails if built on XP Home machine

  I have been developing an application that utilizes .Net remoting as well as some unmanaged code. It is written in C# and uses Windows Forms (no ASP, SQL, etc). I have been building it on an XP Home machine and testing it on multiple XP Pro machines. After a recent enhancement, if the app is built on XP Home and run on XP Home, it locks up the OS requiring a reboot. If that same build is run on an XP Pro system, it silently fails (hangs) but doesn't crash the system. If I build the app on an XP Pro system, I don't have this problem. In attempting to debug this I tracked the code into a thread Start method. Executing the Thread Start crashes the Home system. I admit I am making an assumption about Home vs. Pro but, other than one bein ...Show All

• .NET Development Please Heeelp I don't know what's wrong

  Hi I'm new to ADO in Visual Basic.Net and have problems with updating the DataSet. I'm using the code below, but after I have used the DataAdapter's Update metod nothing happens to the Dataset OR the database (the record is not deleted). Before I used the ExecuteNonQuery, then the record was gone in the database but the record was still in the DataSet. I were told not to use the ExecuteNonQuery, so I commented it. I have seen example where I should use Me.OleDbDAFilmKat.Fill(DSFilm, "Film") instead, but it didn't help. I have also seen articles there I should use this code Dim oRow as DataRow oRow = Me.DSFilm.Tables("Film").Rows(0) oRow.Delete() Then after that, use the DeleteCommand for the DataAdapter.
