The application which was working fine before, suddenly throwing exceptions.
When I debugged I found this error and it happens in the Main()
An unhandled exception of type 'System.InvalidOperationException' occurred in system.dll
Additional information: Process performance counter is disabled, so the requested operation cannot be performed.
What's the heck is this error?

Have you tried something like (just a shot in the dark):
string proc=Process.GetCurrentProcess().ProcessName.ToString();

As per MSDN, I set the Disable Performance Counters in registry to 0 and it worked.
My question, why all of sudden this error came up?
I will try your tip.
Thx

Didn't work. 
Right now, changing the value in Registry makes it work.

How can I select a part of an image and copy/paste it? Something like Paint and other image editors do.

Mazy, take a look at Nish's article: Clipboard handling with .NET[^]. He discusses how to do this with the Clipboard.SetDataObject() and Clipboard.GetDataObject() methods.

My message didn't show up on this board because of a bug or something so I'm posting again:
If you put a WebBrowser control in a Form, and then put that Form inside another Form (set it's Parent to the other form and set TopLevel to false, which is perfectly legal according to the docs), then when you quit your application (close the outer Form), it will stay resident in memory and eat up 100% of CPU time. (You can see it doing this in the Task Manager). This is probably caused by that OLEinPlace stuff somehow but I don't know OLE so that's totally a guess.
This is a HUGE problem for me!!

Sounds like something that should be simple enough, but I can't find anything on the topic. I have noticed a few references, but they're not encouraging... Words to the effect that it can't be done.
Thanks.

If you want to set them at design time, use the properties of the data grid...
Click on the data Grid; in the Properties panel, you should find a row for "TableStyles" with value "(Collection)" and a "..." button. Click on that, and you access the dialog through which you can set up the table style...
you can add a new table style (or modify one that you already have), and in the right-hand side of this dialog you should find the Misc > GridColumnStyles property (with value "(Collection)" and the "..." button). Click on the "..." button to access the dialog to set up the column styles for the given table style.
You can add a new column style or modify a pre-existing one.
Each such column style has a HeaderText property you can set as needed.
If you wish to do all this at run-time, I suggest doing it once at design time and taking a look at the code generated by the Studio for you...
HTH,

I don't have a problem with column headers, and I am creating them at run-time.
I can't figure out how to label the rows!

Ooops ! My bad... sorry.
I don't know if/how you could set the row headers...
ALl I can think of is the RowHeaderWidth property of the data grid to set the width,
and the RowHeaderVisible property of the TableStyles to determine whether they are visible or not,
but I've never seen a place where you can set a row header label (or such...)...
I wouldn't be surprised if this is not allowed, since the DataGrid uses the row header (if they are
visible) to place the + symbol for a record leading to child records in another table...
Wish I could be more helpfull,

Thanks... I'm new to C#, and the datagrid control. I may have selected the wrong control for the task. I was looking for the following functionality...
Row and column labels (datagrid has column labels, but not row labels)
User editable fields within the table (datagrid supports this)
bi-directional linkage to a datasource (datagrid supports this)
cut and paste cells between tables (don't think so)
The datagrid looked like a good choice, but I keep running into hurdles as if it was really meant for another application.

From what you describe, I would use the DataGrid.
As far as the row headers...
..depending on why/how you need them, it may be that you could use
the first column as "row header"... it's a work-around, and
it might not suite your application, but that's all I can suggest right now...
..after all the dataGrid seems to fit all of your other requirements, except for the
"cut-n-paste" across tables (hmmm... sounds like fun!).
Is the data grid's data source going to link you to a DB?
Are you looking for row headers because you know that you will always
display a given number of rows, and that each row represents something
specific? (in this case you might use simple labels, and separate
text controls to display the data instead of the data grid..)

I was considering using the first row as the label, and I might end up doing that if all else fails. Right now I'm taking another look at the ListView control, but I'm starting the learning curve all over again!  I want to learn C#, but it's becoming difficult to resist the temptation to jump back to C++.
Thanks again for your time.

Use the ItemCreated event to add whatever text you want to the datagrid row.
|
|
|
|

Sounds interesting, but I don't see the ItemCreated Event in the datagrid class... Like I said earlier, I'm new to C# and the property soup for the various controls. I'm probably missing something obvious!

I have a fileSystemWatcher object to watch for file changes under some directory and display a message for each file change. However, enven though I change the file only once, the message get displayed twice. The file is a .txt file. Anybody knows why this happens and how to fix it?
Thanks a lot

Greetings,
I have created a custom collection class that I would like to return from a function (i.e. return customcollection;). However, a runtime error is generated when I call the function that's suppose to return the custom collection class. The error states that I should be returning the object type that's contained in the custom collection. (i.e. if my custom collection holds customer objects, then I should be returning a customer object, not the customcollection object.) The problem is that I need the collection returned with all the customer objects that it contains. (I want to bind this collection to a datagrid) Can anyone help me out with this. I know it's something simple that I'm missing.
Thanks in advance,
Andrew

My $0.02:
Sounds to me like a case of mis-match between the function signature and the function code.
What is your function's signature?
For instance, if it is
public myObject myFunction()
You should return an object of type myObject, but if it is
public myCollection myFunction()
you should be able to return an object of type myCollection, and I don't think anyone
-let alone the compiler- would look at what the myCollection object is holding...
Maybe you could post a snipplet?
HTH,
Frank

Frank,
It looks like I'm on the right track, this is basically what I've got:
public IndividualCustomerCollection findCustomer()
{
IndividualCustomerCollection search_results = new IndividualCustomerCollection();
search_results.Add(new IndividualCustomer("John", "Smith", "(905) 428-1122"));
return search_results;
}
Your help is much appreciated,
Andrew
