LOL.. ok but I still can't seem to get the SQL to work.. Could you take a look at my two tables from the previous post and what I need it to do and see whats wrong? Its not getting the right information.. I tried changing it many different ways
|
|
|
|

The problem might be this:
ON [Admin_Table.ID] = [User_Submit.Assigned]

I've got a BackgroundWorker that's supposed to perform processing on a 1gb file, but the worker is completing immediately before it even gets to the processing code in the DoWork event handler.
When I put a breakpoint on the first line in the event handler, it tells me this:
Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.<br />
What the hell does that mean?
I'm setting up the backgroundworker object like so:
encryptWorker = new BackgroundWorker();
encryptWorker.WorkerReportsProgress = true;
encryptWorker.WorkerSupportsCancellation = true;
encryptWorker.DoWork += new System.ComponentModel.DoWorkEventHandler(encryptWorker_DoWork);
encryptWorker.RunWorkerCompleted += new System.ComponentModel.RunWorkerCompletedEventHandler(encryptWorker_RunWorkerCompleted);
encryptWorker.ProgressChanged += new System.ComponentModel.ProgressChangedEventHandler(encryptWorker_ProgressChanged);
I'm calling it like so. I've set a breakpoint on the last line in this block and have verified that the nextFile object is valid:
FileItem nextFile = m_filesToProcess[0];
this.m_fileBeingProcessed = nextFile;
while (this.encryptWorker.IsBusy)
{
Thread.Sleep(500);
}
this.progressBar.Value = 0;
this.encryptWorker.RunWorkerAsync(nextFile);
The DoWork function looks like this:
private void encryptWorker_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker thisWorker = sender as BackgroundWorker;
FileItem fileItem = e.Argument as FileItem;
if (fileItem.Toggle == EncryptToggle.Encrypt)
{
switch (fileItem.EncryptType)
{
case "blah blah" :
{
FileEncryptor encryptor = new FileEncryptor(thisWorker, fileItem);
encryptor.EncryptFile();
}
break;
}
}
}
}
}
When I set a breakpoint on the first line of the function above, it takes a few seconds for the cursor to become available, and when I pressed F10 (or F11) to step over the line, none of the subsequent lines are executed, and the Completed event handler is called.
What have I done wrong?

Does your encryptWorker_RunWorkerCompleted ever get executed?

encryptWorker = new BackgroundWorker();
Did you mean to do that in that order?

Yes. It gets called and the code inside it executes. The progressChanged method never gets called though.

Nah - cut/paste error (and I corrected the message).

and AsyncCompletedEventArgs.Error == null there?

I guess if ReportProgress is never getting called then it wouldn't...
Is it a debugger issue? I can't reproduce it here.

Error, userState, and Result are all null.

I don't know. If I let it run without the debugger, it doesn't crash. If I try to run it under the debugger, all hell breaks loose.

Hmm beats me - I'm on 2008.
FWIW here's my test code, stolen from the docs:
private System.ComponentModel.BackgroundWorker backgroundWorker1;
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
for (int i = 0; i < 5; i++)
{
Thread.Sleep(1000);
this.backgroundWorker1.ReportProgress(i * 20);
}
e.Result = string.Format("**** Result String!");
this.backgroundWorker1.ReportProgress(100);
System.Diagnostics.Trace.WriteLine("**** End of DoWork");
}
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
System.Diagnostics.Trace.WriteLine("**** RunWorkerCompleted");
if (e.Error != null)
{
System.Diagnostics.Trace.WriteLine(e.Error.Message);
}
else if (e.Cancelled)
{
System.Diagnostics.Trace.WriteLine("Canceled");
}
else
{
System.Diagnostics.Trace.WriteLine(e.Result.ToString());
}
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
System.Diagnostics.Trace.WriteLine(string.Format("**** ProgressChanged {0}%", e.ProgressPercentage));
}
...
this.backgroundWorker1 = new System.ComponentModel.BackgroundWorker();
this.backgroundWorker1.WorkerReportsProgress = true;
this.backgroundWorker1.WorkerSupportsCancellation = false;
this.backgroundWorker1.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
this.backgroundWorker1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorker1_RunWorkerCompleted);
this.backgroundWorker1.ProgressChanged += new ProgressChangedEventHandler(backgroundWorker1_ProgressChanged);
this.backgroundWorker1.RunWorkerAsync();

BTW, why do you have the "while (this.encryptWorker.IsBusy)"
loop before the RunWorkerAsync() call?

Hi John,
does this[^] help? The first hit seems to give a kind of workaround...
|
|
|
|
|
I presume this is a Windows.Forms application?
|
|
|
|
|
Yes, it's windows forms app...
BTW, I'm using VS2005, and at this time, I can't switch to VS2008 (just heading off a suggestion to try VS2008).
BTW, even if I reduce the worker contents to its simplest form, I still get the problem.

Some of the properties in a class I was trying to use were not simple set/get properties. As soon as I change them, everything was okay.

I'm making some custom controls basically, just to control the look of stuff.
I have a "LookAndFeel" class which contains properties to keep the Font, BackColor, ForeColor and stuff consistent through out the app.
The Font and ForeColor are fine... the BackColor is doing something I don't understand.
I have this in a Button control and I set the BackColor in my class to MediumPurple... when I drop the button on a form, it is displaying the normal default gray. The property windows says it should be MediumPurple and in the designer it is clearly set to MediumPurple. Everything else is working except BackColor 
What am I missing here?
Thanks.

It's really weird too... for like a split second after dropping the button, it is MediumPurple... then it changes to Gray.
I don't get it.
|
|
|
|
|
I'm not seeing that problem (in VS 2008).
Do other controls appear as expected?
|
|
|
|
|
Yes they do... I'm working in vs05. this is just weird.
Everything else I assign a value to works, except BackColor.
|
|
|
|
|
I just tried it in VS2005 with no trouble, so there must be something in your code.
At which point do you set the BackColor?
|
|
|
|
|
Hi...
The "UseVisualStyleBackColor" property we set to "True", set to "False" this works.
Thank you for the reply.

hi,
I used below code for get mht file from given URL.
But sometimes it dosn't work and wait.
CDO.Message msg = new CDO.MessageClass();
ADODB.Stream stm = null;
byte[] data;
msg.MimeFormatted = true;
msg.CreateMHTMLBody(givenUrl, CDO.CdoMHTMLFlags.cdoSuppressAll, "", "");
string path = destinationPath + "\\" + fileName;
stm = msg.GetStream();
stm.SaveToFile(path, ADODB.SaveOptionsEnum.adSaveCreateOverWrite);
msg = null;
stm.Close();
when I debugged the code I saw this error in:
msg
--[CDO.MessageClass]
---- all items has error
"Cannot evaluate expression because a native frame is on top of the call stack"
it was stuck at this line :
msg.CreateMHTMLBody(givenUrl, CDO.CdoMHTMLFlags.cdoSuppressAll, "", "");
are there any way to get if isTimeout or not?
thanx...

If you stop the code in the middle of unmanaged code, the debugger can't reach the items on the stack that is created by the managed objects because it doesn't know the size of the unmanaged stack frame. You have to step through the unmanaged code back into the managed code before the debugger can show you the contents of the stack.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
Yes, you are right.
I got it.
I need timeout option, but there is no timeout property or parameter etc...
I tested again the code if it will stuck or won't.
It is still same but after 4-5 minutes it was aborted and it worked.
4-5 minutes is too long for me.
I will work with thousands url, I can't wait 5 minutes for each url.
How can it continue after 15 seconds?
Is it possible?
