I have a form with a tab control with several tabs. The main tab has many controls on it. The app is performing various "tests" and displaying pass/fail in the main tab. One of the tests is a communication test. It sends out a message and expects an asynchronous reply within a certain timeout.
When I click on a tab and then go back to the main tab, it takes almost a second for all the controls to be repainted. This causes the CPU to peg at 100% usage and will occasionally cause my communication test to timeout (the timer expires before the reply is received).
Does anyone have any ideas to get around this problem? I have already increased the timeout period as much as I want to. I also do not want to disable the test when I switch tabs.
Thanks

Just brainstorming but I would think about threading the UI and try to get a lazier load if possible.
Here are the articles I have used

You were correct! I was doing everything inside the UI thread. I redesigned the app to use threads for each of my tests. Now the test never fails, even when the CPU is maxed at 100%!!!

Great to hear did you get a chance to work with the background worker object or did you write your own threading class?

I am building an application which will run on PocketPC (2003 SE and Mobile 5.0) Devices (barcode scanners) located in different companies who will use my application.
As part of the application, the application will connect to a webservice (which I am also writing) running at the company location (ie, each company has their own IIS WebService).
I am aware of the Dynamic URL setting. Not a problem. However, everything that I am reading talks about establishing the configuration prior to distribution.
The Problem: Each Company will logically setup their web services with a different URL: ie, http://192.168.0.4/webservicename , http://companymachine/webservicename ). In looking for this answer, I have not come up with any discussion about the ability or sample code.
I am looking for VB.NET code which will permit administration to either enter the webservice URL on the PocketPC device or code which will pull in the WebService URL from a file (TXT or XML) on the Pocket PC device.
The thought is if the PocketPC Application can read the URL values from a file, then the PocketPC Application can be distributed globally to different companies and each company is then in the position to provide their unique URL. The alternative is to maintain builds for each company location which would be an insanely inefficient approach.

Hi i have two html pages...,

Why not just pass the 4 hyperlinks to the second page and set them manually when you transfer control to it? You could also do the same with just passing a single value to the second page and setting 4 textboxes with links to the specific values you want to display.

Here's an article with some sample code on how to pass information from one html page to another: http://www.vbdotnetheaven.com/UploadFile/avi_sanjay/ServerTransfer02222007000910AM/ServerTransfer.aspx
You can transfer which link they clicked on from the first page (or make it have two buttons instead or something). Or, even better, why not just have three html pages in this format:
Page 1:
Click Link/Button 1 - Goto page 2
Click Link/Button 2 - Goto page 3
That way you don't have to do anything fancy to make it work.

I want to write an application in vb.net which will accept input only from the keyboard numeric keys. Can anyone pls suggest how do i go about it..

Put this in the forms keydown event, it will block all keys other than the numpad:
If e.KeyCode < Keys.NumPad0 OrElse e.KeyCode > Keys.NumPad9 Then<br />
e.handled = true<br />
End If
This works because all keys are numbered and the numpad keys are numbered consecutively. This statement rejects all keys that don't fit between the 0 and 9 on the numpad. Make sure the forms keypreivew property is set to true.
This will allow top numbers and numpad(I think).
If e.KeyCode < Keys.D0 OrElse e.KeyCode > Keys.D9 Then<br />
e.Handled = True<br />
elseIf e.KeyCode < Keys.NumPad0 OrElse e.KeyCode > Keys.NumPad9 Then<br />
e.Handled = True<br />
End If

dim keyascii as short= Asc(eventargs.keychar)<br />
select case keyascii<br />
case 48 to 57 ' numeric keys 0 to 9 <br />
case 8 ' backspace<br />
case else ' other keys<br />
keyascii = 0<br />
end select<br />

Hi everyone,
I was wondering, what would be the correct way of formatting a number, based on regional settings.
For example:
Dim value as double = 123456.78<br />
Label1.Text = value
The label would show:
123456.78
I need it to show:
123,456.78 if I'm in the UK
123.456,78 if I'm in Europe
I'm sure its a simple Format problem. Just cant remember.
Any ideas
Mark

Use the format string "N2" to format the number. It will give you the correct format for the current regional settings.

Last time I checked UK was still part of Europe.

But how do I should I use it?
I tried Label1.text = String.Format(value, "N2") and it didnt work.
As for Europe, appologies, I meant countries like Germany represent decimals and thousand seperators differently to UK.

Tip: "didnt work" is not a very good problem description.
Use it like this:
Label1.text = value.ToString("N2")
or like this:
Label1.text = String.Format("{0:N2}", value)
