Hi
I am using the following statement:

cmdSearch.CommandText = "select doctitle, filename, characterization, hitcount from SCOPE
('" /dotNet "') where FREETEXT ( '" + searchText + "') ";

but it is showing an error for /dotnet, it has a problem with the /
How can I edit the query so it allows the /, is it a banned character so to speak

thanks

/ is used as an escape character. For example /" is how you put quotes in your string. Putting a @ at the start of the string turns these off, and will fix your code. Or you can use // to escape a /.

thanks for the reply

I am using the article below
http://www.codeproject.com/KB/aspnet/IndexingServer.aspx

and trying to include the following line:

FROM SCOPE(' SHALLOW TRAVERSAL OF ("/", "/Help") ')

but it wont allow me to add it as it says there is a syntax error, why would this be?

thanks!

string selectintranetquery = "select doctitle, filename, vpath, rank, characterization, hitcount
FROM SCOPE(' SHALLOW TRAVERSAL OF ("/", "/Myfile") ') where FREETEXT(Contents, '" + searchText + "') order by rank asc ";

for the reason I told you, but in reverse. C# can't tell when you mean a " to be in the string, because you're not escaping it.

string selectintranetquery = @"select doctitle, filename, vpath, rank, characterization, hitcount
FROM SCOPE(' SHALLOW TRAVERSAL OF (""/"", ""/Myfile"") ') where FREETEXT(Contents, '" + searchText + "') order by rank asc ";

note that you use "" to get quotes when using @.

No, it's not. You are thinking of the backslash character: \

Hi friends

I have a page where an is present.
Am setting the src of this image dynamically.

If img1.src = "" or empty, i dont want the cross ('X') symbol to be displayed.
Instead, some image which gives some meaning should be displayed.

Can anyone please help me out?

Thanks!

pass value from HTML to .aspx page

You can't. You need to set the src to the image you want to show. binarywrite only works to send an image through a http handler if you want to show more than just the image.

You need to put the values on your link, and read them off the query string.

1.Passing the value through query string
2.If the action is mapped to the aspx page in your HTML form then you can access the fields through Request object in your aspx page.

i.e something like this..

...

3.I think it can be passed through session also ...but I'm not sure!! Google it.

3 - no. How would a html page put something in the session, which is on the server ? It would have to be turned in to an ASPX

As i said earlier I'm not sure about it...Thanks for confirming it Smile | :)

Actually long back I've read an article about it so i was little apprehensive.

Possibly an incomplete read of the article. That article should have guided you a postback to the server either through an hidden form or XmlHttp to an ASPX page that does the saving the data to a session store.

Hello!

I´ve got a number of validators on a page. I display the errormessages they generate in a ValidationSummary-control. I dont want the actual errormessage to show twice, so I´ve got property Display set to None on all the validators. Problem is this:

Im in a textbox with a requiredfieldvalidator pointed at it. I press enter, and nothing happens. No error message in the summarycontrol, no nothing. If I remove the Display=None from the validator I get the errormessage, but only in the validator not in the summary. I´ve got EnableClientScript set to trueon my summarycontrol, shouldnt I get the errormessage there right away? Not I´ve got to press a button or something in order for the errormessage to show there.

Christian Graus20-May-08 23:43

There's two properties ( text and error from memory ), and you can set one to blank and the other to the text for the summary. If you set only one, they both are teh same.

Thanks for your reply. But I don´t understand exactly what you mean. Does the Summary-control have two properties I need to set? This is what it looks like now:

<asp:validationsummary id="valSummary">
              runat="server"
              DisplayMode="List"
              ShowSummary="true"
              EnableClientScript="true"
              ShowMessageBox="false"
              HeaderText="yadayada></asp:validationsummary>

Christian Graus21-May-08 1:18

21-May-08 1:18

No, the validators do.

You mean Text and ErrorMessage? I´ve tried giving both value but the problem remains Frown | :(

EDIT: I might add that the problem only occurs if I leave textbox blank. If I type in a few letters and press enter all the validators show correct messages in the summarycontrol.
