Hmm.....
Thanx for ur advice......
But what the hidden textbox is for?????
and also when I put a text change event on the textbox......should it be raised for each character scanned by the scanner.......OR it will raise a single event for the Barcode scan

The hidden textbox has focus so it recieves the text string from the barcode scanner. It could easily be not hidden but we use it in a POS so it is hidden. the textchange will fire for each character but the scanner should append a particular character to mark the end so you simply check for the first character to confirm it is a barcode then check for the last character which you know marks the end of the barcode. You can then do whatever with the barcode and clear the textbox.

That is in the documentation you get with the hardware. It also tells you how to set it up for different languages.

Please help me to find a solution

I am building a VB.Net client application. On one form, I have an AxWebBrowser control that I am using to render an HTML form. The application also lets the user select a default Printer and Fax from the available printer drivers, but maintains these defaults within the application and not using Windows standard functions. (I recognize this is not good, but we have requirements that force us outside of the standards).
Anyway, I have the ability, from the AxWebBrowser control to bring up the standard print dialog. I also have the ability to print directly to the default printer without the standard print dialog. Instead, however, I need to print directly to the printer that the user selected from the application as their standard printer (which may not be the default).
Does anyone have any suggestions on how to do this?
As an alternative, I have found that using the PrintDocument object, I can print to whatever printer I want fairly easily. The problem, however, is getting the HTML formatted into the PrintDocument object. If anyone has suggestions on that, it would be just as beneficial from my perspective.
Any help would be greatly appreciated.

I am trying to change the height and width of a label, when I change it in code I get no error but it does not change. Any ideas why?
I am trying to make a tall label (vertical)
lblslots(I).Height = 125
lblslots(I).Width = 15
I can draw on like this on a form.
|
|
|
|
|
Double-check the .AutoSize propety on the label, I believe it's set to TRUE as a default.

I want to know exactly what is IspostBack() in vb.net?
When we have to use this?
Why we have to use this?
|
|
|
|
|
IsPOstback is part of ASP.NET. When you first load a page, it's not a postback. When your page is manipulated in such a way that the page is reloaded, so another instance of this class is generated and run, viewstate is loaded, and the page responds to some event, basically, it's a postback. The obvious reason to use this is that if you have a drop down list on the page, the first time your page loads, you need to populate it. After this, if you were to populate it again, you would lose the selected item, and you don't need to, as the contents are already loaded and stored in viewstate. The same holds true for other databound controls, and databound controls would be the major reason to check for postback, if only to save database resources.

Ok now I am geting the clear picture of IsPOstback() function. To be more confident I will just summerize what I have understtod from ur response.
1. If I am displaying list screen then no need to call the bind function inside IsPostBack() function.
2. If I anywhere needs viewstate then it should be called or binded inside IsPostBack() function
|
|
|
|
|
IsPostBack is a property of the WebForm, not a function. It is used to determine whether the page is being loaded in response to a client postback, or if it is being loaded and accessed for the first time.
<br />
If IsPostBack() Then<br />
'Page is being loaded in response to a client postback<br />
Else<br />
'Page is being loaded and accessed for the first time<br />
End If<br />
Hope this helps

There could be many reasons why it won't work on the laptop. The first one being the differences in the O/S installation between the desktop and laptop (are they the SAME O/S version, patch level, etc etc???) Try running it on a different laptop, reinstall all supporting software etc.

well steve i have checked it all ...and the OS verison and other patches are already installed.....well i have tried it on 2 laptops...but the same problem of truncation of values in the hashtable object of VB.Net is there.

OK,
Are you saying that
1) The application works fine on a desktop to which it has been deployed?
or
2) The application works fine on the desktop on which it was developed?
If the answer is numer 2, the problem may have nothing to do with the laptop versus desktop. Try the deployment on a clean desktop - i.e. no dev tools. I have a feeling it will not work on that desktop either.
Sounds suspiciously like a setup problem, not a "desktop vs laptop" problem.

I does not sound suspicous at all.
I have found many reasons why this could be.
Newer laptops, do not include all .NET framework dll's.
Worse over, they will not allow them to be installed!
This makes no sense, and essentially makes Microsoft a liar!
The documentation never said this would be, in fact the opposite.
I would not have changed to NET, had I known this.
This is the type of thing, that keeps terrorism alive and well.
I found this out recently, but unfortuneatly I have already extended myself into the.NET conversion.
