Hello. I'm migrating an application that connects to a remote machine. Before it used sockets, and now a web service. I'm not sure about how to control the time to wait for a response. I'm looking for a kind of timer that waits some time and if it has no response, throws an exception.
How can I do that?
Regards,
Diego F.

You can set the amount of time the webservice will work before sending back an error by setting the executionTimeout attribute in the web.config. Just like you would for a website, like this:
<httpRuntime executionTimeout="180"/>
Then you can put your call to the webservice in a try catch block. The timeout error is a System.Net.WebException. You may want to make sure the message includes the correct error message, though, since there are other System.Net.WebExceptions that could fire. So it would look something like this:
Try
myWebService.MyWebServiceMethod(parm1)
Catch ex as System.Net.WebException
If ex.Message.ToUpper.Contains("TIMED OUT") Then
msgbox("Web service method timed out.")
Else
msgbox("Web error: " & ex.Message)
End If
Catch ex as Exception
msgbox("Error: " & ex.Message)
End Try

Hello,
I have a class with many static methods. Now I want call methods from this class during runtime. The name of the method and the parameter names/values are given by string. (Background: The methods contain code for filling comboboxes and I want to write an AJAX-Solution to fill different types of comboboxes initiated by user-click inside a web page)
Now I'm in a state of confusion, if that's possible. NOTE: Must be work with Framework 1.1 !!!
Can anybody help me, please ?

So you want to run a method based on a string that is sent from the client? That's a pretty bad idea, as anyone can send any string to your server to run any method they like.

You are right, but not exactly 
Will make a self written AJAX-call with different parameters. Some parameters describes the call of the method. Please don't panic about the security. Is an internal website with different authorization mechanism.

There's nothing in the Windows API that will tell you this. You'd have to use a third party library, like Nero's SDK, to get that kind of information. Sorry, I don't have any examples.

Thank you,
I try to use Nero and getting this information but with no success.
Someone can help.
Thanks

You should have said that before.
Your best source of information is going to be a support board for the library that your using. I guarantee you that 99.9% of the people here have not used a CD Burning library.

Thanks in advance,
P.S - I am unable to set the mappingname property in the tablestyle to collection.
if you send a mail at gokhale.i1@gmail.com in response to this query it would be better...

Hi, I designed my application in vb2005. I have a windows form application and contain combobox. My combo box contain an item and i set a dropdownstyle property to dropdownlist.
The problem occure when i try to delete the text from the combobox. I try to write the code combo1.text="" but the text still remain the combobox. Can anyone help me to solve this problem?
Thank in advance
|
|
|
|
|
try combo1.selectedtext=""
but why would you want to delete the text?
If it is because there is text in it the moment you start you form then you should put the selectedindex to -1
combo1.selectedindex=-1
you can also try
combo1.selecteditem=nothing
since you have set the property to dropdownlist the user can not type into it so the text displayed is whitout a doubt a item and therefor the selecteditem or selectedindex will most likly work best
If my help was helpfull let me know, if not let me know why.
The only way we learn is by making mistaks.

Thx in advance!

Draw it to an image then repaint the image.

It's a common technique. Create a Bitmap the size of your drawing area, destroying and recreating a new one of appropriate size as your control resizes, and draw everything to this buffer. When you get a Paint event, draw the buffer to the screen.
|

|

Alternatively, you can split your code in two parts:
1. do the lengthy calculations and save their results in some data structure, without
drawing anything, then call Invalidate()
2. in your Paint handler, paint the drawing based on the content of your data structure
You have to balance this approach to the one based on a hidden bitmap: if you need lots
of resizing, this approach may be more appropriate since you can resize analytically
rather than by the pixels. If your output is more of a painting than a drawing, having
a bitmap probably would be better.

thx all for the replies!
I'll use a bitmap and then redraw it out using but im yet to test it.
Ive' got another question to add; by implying the methods of saving onto a bitmap and redrawing it out smoothens the paint process? or i'll still be seeing flickerings like im seeing it now, its nth major actually but it just bothers the mind seeking perfection.! 
and the fact that when i actualy do systems testing, i would wanna push it to the limits.
thx again!
regards,
jensen!
