• Visual Basic IDE VERY SLOW WHEN PROJECT IS OPEN BY ANOTHER

• Visual Studio Express Editions VB 2005 - Compositing Operations (C.O.)

  Hello Community! I'm quite new in VB (just since November06 ) and I'm looking for a fast way to overlap greyscale bitmaps in VB2005 (i.e. for every pixel R=G=B). I tryed to use the alpha-blending tchnique but it doesn't fit my porpouses (after I perform the C. O. the overlapping region is darkned). I would like the overlapping process to be a lightening process (the resultant color is always at least as light as either of the two costituent colors). In particular overlapping any color with white should produce white. Overlapping any color with black should leave the original color unchanged. I found an interesting program in VB6 that seems to to that http://www.vbaccelerator.com/home/VB/Code/vbMedia/Image_Processing/Compositing/arti ...Show All

• Smart Device Development Debugging very slow

  I have recently converted an application from VS.NET 2003 to VS.NET 2005. In VS.NET 2005, when I set a breakpoint and try to Step Into (F11) or Step Over (F10) lines of code the response time to get to the next line is about 4-5 seconds. This occurs with even very basic lines of code (such as x += 1). Debugging the same project in VS.NET 2003 had no noticeable lag time for Stepping Into simple lines of code. The application also runs normally on the device (in VS.NET 2005 debugger) when no breakpoints are set. I am debugging on a Dell Axim X51v Windows Mobile 5 device (not emulator), using wireless connection and static IP address. Can anyone tell me what the problem may be or what I should look at in my environment to fix the issue ...Show All

• Visual Studio Express Editions media time calculation

  Hi need the maths calculation for this: Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If OpenFileDialog1.ShowDialog Then mplayer1.URL = OpenFileDialog1.FileName Timer1.Enabled = True Private Sub Timer1_Tick( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Label1.Text = mplayer1.currentMedia.duration But It displays the length as 345.232 for example. how would I format this as 3:00 for example it may well be achievable.

• .NET Development UDP Socket.Receive() on more than one port

  I have to connect to a multicast group that sends out several thousand data feeds, each on it's own port. I want to create one instance of a UDP Socket on a dedicated thread, then use blocking Receive() to catch the datagrams. My problem is that it seems that Socket.Receive can only listen to one port at a time. I don't want to call BeginReceive for each port, because I don't want to use the threadpool. Any ideas Socket.ReceiveFrom(/*........*/); It's Specifically for Connectionless (UDP) Sockets... And You can Specify from Which End Point you have to receive... You can call this by specifying different end points on the same object of UDP socket object. Best Regards, Rizwan ...Show All

• Windows Forms Loading forms

  How can I load forms explicitly without showing them. Like there was a function Load (form_name) in VB6.0 that could be used to load forms without showing it. How can I achieve the same effect in VB2005 Thanx, I specifically wanted a way to trigger the Load event, but shifting my code to New will also do, in my case. As an aside, is there any way of trigeering the Load event without showing the form ( just in case, it is not possible to shift my code to the New from the Load event) ...Show All

• Visual Basic Dead Keys and KeyPress event

  Hi. I am designing a program to convert normal latin/american characters to cyrillic characters when a certain key is pressed, for example, when I press a letter in my keyboard, the program checks which letter was pressed and accordingly converts it to a specific cyrillic letter defined by me (Yes, I have a huge Case statement for each keyboard letter). I'm currently using the KeyPress event to do this. Here is a brief bit of example that is working, so you can see what I mean: Private Sub frmMain_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyPress LatKey = e.keychar Select Case LatKey Case "q" CyrKey = " " Case "w" CyrKey = " &q ...Show All
