Hi mav,

thanx for ur efforts but i think i made actually not good solution but i think it work at this time
this is the code(please tell me if any notes)

Graphics grfx = this.CreateGraphics();
Pen pen = new Pen(mainScreen.DefaultBackColor);
if (counter == 0)
{
lastPntOfLine = e.Location;
counter++;
}
else
grfx.DrawLine(pen, mLineBeginPnt, lastPntOfLine);
mLineEndPnt = e.Location;
grfx.DrawLine(Pens.Black, mLineBeginPnt, mLineEndPnt);
lastPntOfLine = e.Location;
grfx.Dispose();
pen.Dispose();
Invalidate();

i felt very stubid to write that but this is my thinking until now

Capture a flash window and stretch blit to the desktop in realtime? [modified]

I've gotten as far with this as using getDC to draw to the desktop and some window picker code I found on this site. What I've yet to discover are:

i) How to trigger a handler every time the flash window has finished updating so that I can capture the bitmap at that point.

ii) How to blit to the desktop only after the flash window (or all windows) have updated, but still while the monitor beam is at the top of the screen.

(The directx full screen support addition to the latest flash won't help in this case -- i.e. for existing swf's. The task is to resize existing non-interactive animations at a decent frame rate..)

Any help appreciated, thanks.

The biggest problem your facing is that you can't determine when the Flash window finishes it's painting. There is no notification given that signals the painting completion. You also can't determine when the scan is at the top of the monitor. Hardware interaction isn't available to your app without you writing driver-level code.

TWAIN is the mechanism most scanners use, although some may use WIA, I guess. There is no built in TWAIN support, but there are commercial and ( I think ) free libraries around. CP has at least one free C++ TWAIN library, and perhaps some .NET ones.

Take a look at the NetworkStream class.

Depends on your definition of chars.

Find a way to read in bytes of data from the microphone and then you can write then to a NetworkStream.

I'm sorry if this's a repost "I just did last night" but I just cant find an answer for that..
Any idea about how to disconnect from the internet using this RAS thing?? It's just not working for me Sigh | :sigh:

I tried this

private void btnDisconnect_Click(object sender, EventArgs e)
{
    try
    {
        RASCONN lprasConn = new RASCONN();
        lprasConn.hrasconn = IntPtr.Zero;
        IntPtr m_ConnectedRasHandle;
        m_ConnectedRasHandle = lprasConn.hrasconn;

        RasStats stats = new RasStats();
        RAS.RasGetConnectionStatistics(lprasConn.hrasconn, stats);

        int Minutes = ((stats.dwConnectDuration) / 60);
        MessageBox.Show(Minutes.ToString());

        MessageBox.Show(Convert.ToString(RAS.RasHangUp(m_ConnectedRasHandle)));
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

I included a calss called RAS.cs from this article source files and used the code above.

hello
i was assigning a progress bar to a thread which i don't know how much time takes to complete... actually the thread calls a method of a library that i have downloaded from net... so i don't know how to use the step property of the progress bar... please provide a code snippet that shows assigning a progress bar to a thread ... thanx

Your thread cannot interact with the UI. You should use a backgroundworker object, it can send messages back to the UI thread to update a progress bar.

If you don't know how long it will take to complete, you obviously cannot show a progress bar properly, you'd have to show one that just moves from empty to full over and over, as Windows also does at times.

vbscript empty memory from defined variable

hi, i want to know if there is a way in vbscript to empty and remove a declared variable from the memory after defining it, for example:

Dim var1
var1 = "value"

i want not only to empty the value assigned to the var1 variable, i want to remove it from the memory to free it to avoid the space reserved to it in the moemory,

I found that i can use empty and nothing, do they enough to free the memory??? D'Oh! | :doh:

Thanks alot

You should post this in a more appropriate forum. One dedicated to VBScript.

Next time, ask in the Visual Basic Forum.

Yes and no. It depends on the type of the variable and it's context.

No, there is no way to release it. You don't have to worry about it. Just let the runtime take care of it.
