the browser back button will take you back to the page you were just on without going back to the server and re-loading the page, therefore the onload will not run again until the page is refreshed.
The only way i can think is to somehow delete the cache or apply some sort of method to run when the browser back button runs

Hi,
I am developing a application, in which i have to fetch some records from a remote database through web service and then on basis of that data i have to insert some records in our local database and after that i have to mark the remote data that inserted into local db so that it does not comes again.
So in this process after inserting inot local DB if error occurred while doing updation on remote data, then process should be rollback.
that is the issue. I tried using Enterprise Services, but it didn't work, trnsaction won't get rollback.
Can it be possible using WCF?
Please help regarding that.

No. WCF has nothing to do with database updates. It deals with communicating with things.

It was probably already committed. You might want to read up on using transactions in ADO.NET.

Dear Sir,
I am doing Payment Gateway Integration on my system
so for that I have registered one dll on my system.
Payment Gateway Integration is working properly on my system.
Now we have uploaded it on live server but it throw one execption.
Execption is:-
The Server threw an execption (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))
It may be due to missing file or any other reason.
Please suggest me.
Thanks.

If you can't work it out from any of the many full examples that you can find with google, odds are good you should stop wasting your time with trying to write code.

Hi All!
I have to put a validation for Australian License Number.It's required format is as per below.
Validation Maximum length of 9 characters.<br />
Alphanumeric characters only.<br />
Must have at least 4 numeric characters.<br />
Must have no more than 2 alphabetic characters.<br />
The third and fourth characters must be numeric.
can anyone please suggest any custom validation or javascript ?
Thank you,

Sounds like a regular expression to me.

Yes,it can be anything.It may be a regular expression or custom validator or javascript.
Thanks for the response.

Yeah, it COULD be any of those things, but I imagine that a regex is the most logical. expresso is a great tool if you need help working out a regex.

Hi Vasudevan Deepak Kumar,
Thanks for response. I have "Expresso". I have tried this. But I can't figure out the correct expression. I can't make expression with numeric and alphabetic. somewhere I am wrong. I am still playing with "Expresso".....

U can try out for Javascript posted below
Expresso cannot work for the expressions like this. That becomes tough for Expresso.
Try this.. put the code in ur jscript
<br />
function nx(obj)<br />
{<br />
var str = document.getElementById(obj).value;<br />
if(str.length > 3 && str.length < 10)<br />
{<br />
if((str.charCodeAt(2) > 47 && str.charCodeAt(2) < 58) && (str.charCodeAt(3) > 47 && str.charCodeAt(3) < 58)) <br />
{<br />
var c = 0;<br />
var n = 0;<br />
for(i = 0 ; i < str.length ; i++)<br />
{<br />
if(str.charCodeAt(i) > 47 && str.charCodeAt(i) < 58)<br />
{<br />
n++<br />
}<br />
else<br />
{<br />
c++<br />
}<br />
}<br />
if(n < 4 && c > 2)<br />
{<br />
return false<br />
}<br />
else<br />
{<br />
return true;<br />
}<br />
}<br />
else<br />
{<br />
return false;<br />
}<br />
}<br />
else<br />
{<br />
return false;<br />
}<br />
return false;<br />
}<br />
The ASCII part is very Improtent to do the task.
I hope that will help
If work let me know.

I have a directory 'UploadFiles' in my website, and I can forbidden users to visit via *.ASPX page.
(check users right in *.aspx.cs), but i can not forbidden user to visit via directly input URL in browser. like http://localhost/mywebiste/uploadfiles.jpg
I know the MembershipProvider in .NET Framework, but i think it too complex than i wanted.
and i didn't find any document to help me write a good web.config file.
so how can i solve it?

I prefer to write a HTTPHandler which handles JPG extension. Inside the handler, do user authorizations. If user is unauthorized, display relevant messages.

thanks for your reply.
the JPG files just a kind of 'UploadFiles', it contains many different file types, like bmp, txt, doc, xls, mp3, avi, and so on.
i do not want to add a HTTPHander for all file types....
