Hi,
A GUI control can only be updated from the GUI thread.
If you are running a different thread then this must call a function on the GUI thread to perform the update.
you need to use a delegate method and the GUI's InvokeRequired method.
There are a large number of articles on this site that explains this in more detail just search for InvokeRequired
I hope this helps

This is a question better asked in the ASP.NET forum.
I think you're going to have to provide a link to a page that does the export, which you have to write the code for, then this page should return the export as a normal text file, just like if you were sending back an Excel or Word file. I don't know the specifics myself. That's why I said this question is more appropriate for the ASP.NET forum.

hi i am creating a project in which i am trying to create a handler for a funtion
that funtion skeleton is this
Function execcommand(ByVal commndstr As String)
End Function
i am trying to add handler by this command --- > AddHandler execcommand(), AddressOf execcommand
it shows a error
'AddHandler' or 'RemoveHandler' statement event operand must be a dot-qualified expression or a simple name.
can any one tell why this arises and correct the mistake
thank you
with regards

balakpn wrote: addhandler sendcommand(),addressof sendcommand
The format for the AddHandler statement is:
AddHandler object.event, handler
You didn't give AddHandler the name of an object event to handle. Something like:
AddHandler SomeObject.Click, AddressOf SendCommand
The signature for the SendCommand function MUST match the signature of the event it's going to handle.

Hi! I would like to; "really" know how to get the current text line number where the caret is at.
 (not the "line number" just the "text line number":
when you use textbox1.lines(0) it takes the entire text in line 0 even if some text are in line 1, because the text in line 1(as long as it didn't get there by pressing the return key) belongs to line 0, but when I use the code below it just says the text in line 1(even thought it belongs to line 0) as belonging to line 1.)
a = Rtb.GetLineFromCharIndex(rtb.SelectionStart)
So can anyone tell me a way to get the real line number of the selected text.
 thanks in advance
ps:
(pls don't tell me to explain again!

|
|
|
|
|

this smilies have sounds? I don't seem to get any sound at all.

No, they don't.
Putting a bunch of them in your posts turns your post into unreadable noise.

Yes I'm new here, just posted 5 or 6 times so far.
Sorry for any inconvenience.
and sorry about the subject, I was just trying to get some attention to my string, I guess I was wrong, I guess proper subject will get even more attention.
and I didn't know these smilies produced sound, even if it did I didn't get any sound so far.
