Yes i know what a VNC is and what it can be used for but i dont want to use a ready made software.
I am doing the above mentioned as project in my college and i need to submit code there 
So i need to "write" my own version of VNC in any programming language possible.
Any further help appreciated

Then, I suggest looking at existing open source projects so you at least know what you're getting yourself into. It's not as easy as you might think and there is WAY too much to explain in a forum environment. Results...[^]

I am writing a program that needs to launch another program, log in, run another program, and then type in some text or make selections in a list box. I've figured out how to launch the app and get's it's window handle but that's it. I'm at a loss as to how to find the resulting window and send clicks, keystrokes, or whatever. Worse, after intially launching the first app (Citrix, if your are curious), I will be presented with a login screen, a folder with several icons one of which will need to be launched, another login screen, another virtual folder with an app that needs to be run, etc.
So what is the best way to approach this? I've been reading up on the Windows API...
This is frustrating because at home I often use a program called Macro Express to automate this sort of thing.

It's been a while, but I think you want to look at the sendmessagee function in the win32 api.

Well you could use EnumWindows to get the list of all top level windows.
Then you could use EnumChildWindows to get the list of the child compoments inside the parent.
Since you are posting this in VB section i am asuming that you are using VB, then you can use AppActivate to set focus on the window and then SendKeys to send the keys to the window 
To run an application you can use the Shell function which returns the process id if the program is running.
-------------------------------------------
Taken From MSDN 2003
-------------------------------------------
'Example
AppActivate("Untitled - Notepad")
SendKeys.SendWait("Hello world!")
' Send Ctrl S to open the Save As dialog box.
SendKeys.SendWait("^S")
' Send the name of the new file.
SendKeys.SendWait("c:\HelloWorld.txt")
' Send Alt S to save the file.
SendKeys.SendWait("%S")
-------------------------------------------
I hope the above helps

SendKeys!! Thats what I was thinking of...

Yes that does help, thanks. I guess I just need to take them on one by one and see what works by trial and error.

Hi all
I have this project im converting from vb6 to vb.net
when i run the code advisor for vb6 it keep getting this fixit code.
'FIXIT: Declare 'currentdate' and 'tempDay' and 'tempMonth' with an early-bound data type FixIT90210ae-R1672-R1B8ZE
Dim currentdate, tempDay, tempMonth, tempYear As String
Dim tempDate As String
I go to the help file for this fixit but it does not explane it very well. Can any one explane it to me.
The Dim statements are my original code.

Declaring multiple variables with a single "Dim" strongly types only the variables with an "As" clause. So your first declaration declares three variants in VB6 and one string.
You get the message when upgrading since you *may* want to keep it as three objects and one string (the original intent of the VB6 code) - or more likely you originally intended four strings - VB.NET would regard it as four strings.

I am developing a video conferencing program. It is intended to work on internet. I used AVICAP to capture video from webcam. The method i intended to used to stream video is capture a frame from webcam then send it over to the other PC and then repeat it again. The other PC will paste the frame received to the picture box upon receive the bmp file. My problem is I do not know i should choose either TCP/IP, UDP or socket as my connection method? And i do not know how to stream audio captured across internet. Can any1 give some help here either by giving me some sample video conferencing program (vb.Net) or giving some guildance and tutorial ?

What question?
All you've done is copy/paste in your homework assignment. This is a great way to your "question" ignored.
Ask something specific and we can help with that. The whole point of you getting a homework assignmnet is to see if you're understanding the what's being taught in the class and if you understand how to apply it to problems. If all you're doing is copying/pasting the assignment into a forum, ...

You still haven't supplied much information.
I take it you have to control both the position and the size of the circle.
You're drawing a cicle from the top/left corner of the picture box ALL THE TIME. You're not tracking the position of the circle at at all.
You have to track the center of the circle with the two trackbars. Easy enough, you already have them in place. Eliminate all the drawing code from the trackbars, you don't need any of it. The trackbar code will just alter the position and size of the circle. Then call the Invalidate method of the PictureBox control your painting on.
You only need a single Draw statement, inside the Paint event handler for the PictureBox control. Here is where you'll calculate the top/left and bottom/right corners of the box that will be used to draw your circle. It's simple math.
The top/left will be the position of the circle minus hald the diameter. The bottom/right will be the position plus half the diameter.
Don't even thnik of asking for the code. You're in a class to learn to write it yourself.

I took this challenge and found I'm having a tough time understang the logic flow of the object model.
I get the circle to draw in the center of the PictureBox, but it is fleeting - it disappears as soon as it is drawn. I debugged only to find the circle vanishes as soon as I exit the Paint event on the PictureBox.
Where am I failing?
Public Class Form1
Private _paper As Graphics
Private _pen As Pen = New Pen(Color.Black, 3)
Private Sub Form1_Load(....) Handles MyBase.Load
_paper = Me.uxCanvasPicbx.CreateGraphics()
End Sub
Private Sub uxDiameterTrkbar_Scroll(....) Handles uxDiameterTrkbar.Scroll
uxDiameterLbl.Text = uxDiameterTrkbar.Value.ToString
uxCanvasPicbx.Invalidate()
End Sub
Private Sub uxCanvasPicbx_Paint(....) Handles uxCanvasPicbx.Paint
Dim ul, lr As Integer
lr = Me.uxDiameterTrkbar.Value
ul = ((200 - lr) / 2)
_paper.Clear(Color.White)
_paper.DrawEllipse(_pen, ul, ul, lr, lr)
End Sub
End Class

Karen,
Original question that I posted was How do I control the diameter of a circle. I was able to control the Horizontal and the Vertical.
