Hi all,
I read a file and send streams to another method. It's working fine. But all messages are feeding very quickly. So I want to delay within each message. So I do the following
public void ReadFile()<br />
{<br />
<br />
Thread.Sleep(20);<br />
<br />
AnotherMethod(stream);
}
All those things start on a button click event. Once started the process, my GUI get freeze until finish the process. After that I can drag it and so on. Without the thread I use, there is no any issue.
Can someone tell me what should I do to fix this.
Thanks a lot.
I appreciate your help all the time...

BackgroundWorker[^] to simplify things. Or you can create a background Thread.

Problem is you are running the file streaming and sending in the same thread where UI is hosted. Create a new thread and execute the job on it. If you need to update UI from this thread, use Invoke/BeginInvoke. You can also use BackgroundWorker class which makes all these easy.

Yes, I read more about threads and found that the issue here is working on the same thread in UI and the process. So I have to do the process in background.

And why Thread.Sleep()?

Hi all
I have 20 check boxes in my page and i need to fire the checkbox checked event for all check boxes.
Instead of writing the checked event for each and every checkbox is there any way to fire the checked event with only one function.i need to get check box id if it is checked.
I'm doing in C#.Net web application
Thank you.

Write something like this in the constructor or the form's Load event or whatever.
checkBox1.CheckedChanged += checkBox_CheckedChanged
checkBox2.CheckedChanged += checkBox_CheckedChanged
checkBox3.CheckedChanged += checkBox_CheckedChanged
Or you can simply set the CheckedChanged handler function from the Properties window (the Events section) for the checkboxes.
And to know which fired the event, it's the sender argument of the handler.
CheckBox Sender = (CheckBox)sender;

Hello all,
I just found out that I can't bind a DataGridView to an array of DataRows. The reason for wanting an array of DataRows is because I'm performing so very complex filtering that can't be done with the DataTable.DefaultView object. My question is, why does the datagridview accept a dataTable as a dataSource but won't accept an array of dataRows, even though they contain a reference to the dataTable. Is there a way I can create a custom class that implements IListSource and contains datarows from the dataTable? As you well know, an exception is thrown is you try to add a existing row to another dataTable. I want a memory reference instead of the actual values (DataRow.ItemArray) to save memory overhead.
Thanks,
Richard

Like what? and how are you filtering it?
The reason i ask is becuase the DataView class is built for filtering from a DataSet, and you can bind it to the DataGridView.
If you really cant use the DataView, why not build your own dataSet up with your DataRow[]? something like....
DataTable table = new DataTable;
foreach(DataRow currentRow in myDataRowArray)
{
table.Add(currentRow);
}
DataSet.Add(table);
This was done off the top of my head, it might not be 100% correct but the idea of what you need to do is there
Hope this helps

How do i turn an array or an arraylist into a text file?

Iterate the collection and write each element to a StreamWriter.

How do I make the tooltip appear on a datagridviewcell (textBox column) even if the user doesn't move their mouse over it and while it is editing.
I am trying to implement a auto-complete feature that will show a tooltip with a match and ask the user to press a key if it is the correct match. It is identical to Visual Studio when one presses form1.FormClosed += and the tooltip box appears with an auto-complete of the event.
Thanks in advance.

hello....
anybody there?

Hi,
Actually, you don't need to think about locations and positions, just design your reports, you can use the preprinted form as a background (temporary) for alignments, and the printer will take care about the rest. Hope this will help.
best regards,

hi,
I have some applications that connects to databases, i trigger edit/delete/insert and reports from the application.
everytime i trigger some action i open and after close the connection.
my question is; do i win something by opening connection in first time (i trigger whatever) and after that ask if connection is open and if not open it (close connection when formclosing event for exemple).
does it works better, faster, whatever?
(connection_string works and everthing else)
thanks

Not really. Best practice is to open the database only when you need to connect to it when working with the data, then when done working with the data, close the database connection.

You can use P/Invoke to call unmanaged functions.
|

Thanks.
Just read your article on minimizing applications to tray with P/Invoke and user32.dll's unmanaged functions,
Do you know anywhere i could find an example of the unmanaged function i would use to get a list of the icons and their context menus?
