i'd catch the donwloadcomplete event in unit-test and setting a flag (complete=true).
you can start the test then as follows:
<br />
[Test]<br />
public void TestDownload()<br />
{<br />
Downloader.DownloadReady += ...
Downloader.StartDownload(path)<br />
<br />
while (!complete)<br />
Application.DoEvents();<br />
}<br />

WOW ! That's great. Thanks for pointing this out
|

Calling Application.DoEvents is bad practice. It often results in unexpected results, so I would really advice against it.
If you can get a handle to the thread I'd use its Join method. If this isn't the case, you can use an AutoResetEvent to signal from one thread to the other. You can read more about it here[^].
Standards are great! Everybody should have one!

Another simple way is to use Thread.Join() method.....

The way that I have implemented many solutions for this is to use a ManualResetEvent to pause the thread. Then when the work is complete in the second thread, set the ManualResetEvent allowing the first thread to continue.

Hi,
I'm sitting with a weird problem.
I created an application in C# 2005 Express. It has 3 timer controls in it.
The first timer runs as a clock (system clock) and once this timer reaches a specific time during the day it runs its procedure (this works fine)
The 2nd timer has its Interval set to 10min. So every 10 minutes it needs to run its procedure.(doesn't do it)
The 3rd timer has its Interval set to 10Sec. So every 10 second it needs to run its two procedures (doesn't do it either);
Now when i run this app in debug mode everything works perfect. Breakpoints are being reached all the time, I don't see any problems. But once i publish the app and install it on a users machine it doesn't always run the procedures 
As u probably realized is that this application is an auto update app which auto updates data (retrieve data from webservice then update the local SQL database)
Any help would be greatly appreciated. I need to get this working by midday tomorrow.
Any other suggestions would be great.
Thanks

Why don't u use threads to run your code. You can use your time to control the different threads in your app.
|
|
|
|
|
I was doing this but gets too complicated to run one procedure say at 13:00 everyday and 2 other procedures on different time intervals.
If i run a procedure under a timers tick event, isn't that set in its own thread too?
I'm just worried that if two different procedures run at the same time so they don't crash or something.
|
|
|
|
|
try logging some "I'm in this method" statements and see which code is not executed.
debug mode may work since one breakpoint pauses all threads.
|
|
|
|
|
I did that by using message boxes and it worked but then sometimes it just doesn't work.
I have changed some values it seems to be working now but i still feel unsafe.
Will do more tests thanks.

Hi,
When I'm trying to execute the following code, it raises exception saying that "Cross-thread operation not valid: Control 'button1' accessed from a thread other than the thread it was created on."
private void Form1_Load(object sender, EventArgs e)
{
Thread th = new Thread(threadStartServer);
th.Start();
}
private void threadStartServer()
{
string result = "";
TcpListener tcpListener1 = new TcpListener(8080);
tcpListener1.Start();
button1.Text = "Success"; // Here the exception(mentioned in subject) occurs.
}
Please let me know the solution. Thanks in advance.

Hello,
As the error message says it all.
Here is a solution using "InvokeRequired" and "Invoke" (google it)
private void threadStartServer()
{
string result = "";
TcpListener tcpListener1 = new TcpListener(8080);
tcpListener1.Start();
EditButtonText("Success");
}
private delegate void EditButtonTextDelegate(string strArg);
private void EditButtonText(string actText)
{
if(InvokeRequired)
{
Invoke(new EditButtonTextDelegate(EditButtonText), new object[] {actText});
return;
}
button1.Text = actText;
}
Hope it helps!
All the best,
Martin

Thanks for the reply... and helped me get more familiar with the delagate/invoke technique...

You can also use BackGroundWorker class which has ProgressChanged event, allows to access your GUI items.

You can't access the controls which is in the main thread from a thread which is created by you. Check this[^]

Hello Friends,
How can i create 1D image in C#.NET.

Have a think about what 1D means. How would you want to represent that?
A string is one dimensional. An image is not.

Two dimensional. Like your browser window... 
Heres a one-dimensional image library:
class OneDeeImage
{
private Color[] data;
public OneDeeImage(int width)
{
data = new Color[width];
}
}

I am developing an window application in C#.NET and i need to save data in image format so i am using Draw To Bitmap method to do that my code is
Bitmap bi = new Bitmap(panel1.Width, panel1.Height);
bi.SetResolution(3000, 3000);
panel1.DrawToBitmap(bi, new Rectangle(0, 0, panel1.Width, panel1.Height));
bi.Save(@"c:\abc.bmp", ImageFormat.Bmp);
But using this code i am able to get image but that image is not clear can any on help me so i can get clear image..
|

What do you mean when you say that the image "is not clear"?
Why are you specifying the resolution for the image? What are you going to use it for?
Despite everything, the person most likely to be fooling you next is yourself.
