Standard question #2:
What error message do you get?
TAK78 wrote: script &= "setImageArr(" & str & ");"
As you have no variable named str in your server code, a new empty variable is created. This code will therefore not put any parameter in the Javascript code. You should have Option Explicit in your code to protect you from inadvertently create variables.
You have to put quotes or apostrophes around the string value in the Javascript code. Also you have to encode the value properly, or you will have problems with certain characters.
Dim script As String = _
"<script type=""text/javascript"">" + _
"var str='" + val.Replace("\","\\").Replace("'","\'") + "';" + _
"alert(str);" + _
"setImageArr(str);" + _
"</script>"

Thanks a lot works perfect now!!!
So problem was that you have to encode the special characters before you pass it on, right?
Thanks for the help and advice

Not if you write the code as I did, which produces a single call to String.Concat.

The main problem was that you didn't have any apostrophes around the string value.

Do you mean if the textbox where users can enter a search string is focussed, or just at any time when a user presses the return button on the keyboard...

AH!! That's a difficult way to describe your problem...
erhm... If you remove the code from your button click into a seperate function and call that function from your button click...
<br />
private void DoSearch()<br />
{<br />
}<br />
<br />
button_click()<br />
{<br />
DoSearch();<br />
}<br />
You only have to call the same function from your textbox's TextChanged event.
Doubleclick your textbox to generate a TextChanged event handler, and within that event call :
<br />
DoSearch();<br />

Hey guys,
I'm about to develop a webservice, and ofcourse want to secure that properly. I'm not really into webservice security though, thus posting this question. I installed Web Services Enhancements 3.0 which should be capable of helping me out here.
My first goal is to crypt the messages sent from and to the webservice. We don't have an SSL certificate and do not intend to buy one. How can I set up a fairly good encrypted communicating webservice?
I've read this[^] fine document, not helping me out a lot because it assumes I really know everything about webservices.
Anyone??

Hi Rahul,
I am not good in vb
I think you can write the same as
Dim tabrow As TableRow
i = 0
While dr.Read
Dim chkbox As CheckBox = New CheckBox
chkbox.Text = dr(0)
chkbox.CssClass = "pagetext2inside"
chkbox.ID = "chklang" & i
Dim tabcell As TableCell = New TableCell
if (i mod 3)= 0 then
if tabrow.Cells.Count > 0 then
chktable.Rows.Add(tabrow)
end if
tabrow = New TableRow
end if
tabcell.Controls.Add(chkbox)
tabrow.Controls.Add(tabcell)
i = i + 1
End While
dr.Close()
if tabrow.Cells.Count > 0 then
chktable.Rows.Add(tabrow)
end if

1. How can I get the url of the webservice it is running?
a. within the page from web service is being invoked
b. from Within web service
I have web service on multiple servers from it can be invoked. Based on where it is running I have different logic to execute.
2. I want to pass certain information to the web service that can be used between my all web methods. I do not want to pass all the information in webmethods parameters like
<webmethod()>_
Public function MyWebMethod_1(ByVal param1 as string....ByVal paramN as String) As String
...
End function
<webmethod()>_
Public function MyWebMethod_N(ByVal param1 as string....ByVal paramN as String) As String
...
End function
Any idea how can I do this? Can I have properties in web services? Yes, How?

ItemTemplate?? can u plz explain it to me??

Add a new column to your datagrid. Then in the UI you can click the button that says change to template column. when you do this, it will create an item template. Or you can just directly in the html have code like this:
<Columns>
<asp:TemplateColumn
HeaderText="string"
SortExpression="string"
>
<ItemTemplate>
<!-- child controls put your image control here -->
</ItemTemplate>
</asp:TemplateColumn>
Hope that helps.

How do I disable or remove the "Open" option in the file download window in my aspx page? Can somebody please help? Thanks!
I have been used the below code in my page.... That's why, there is no file in my Cache.
Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();

You might not have that much control over the File Download dialog box as it is fully controlled by the web browser. To trigger the dialog, I guess, you should be using Content-Disposition with the full file name like (filename.xls) [including the extension right].
You can tweak the headers and try sending the MimeType which is that of EXE. Normally, for Security reasons, Internet Explorer disables 'Open' for EXE and also the 'Checkbox' right?
But this might not be a complete solution neither a cross-browser compatible one.
