Yes you can do. You can catch the keypress event of keyword from javascript and can take action accordingly.
But there are limitation in using javascript, you need to check with your requirement

Hy,
I have saed a pdf file in the database.i want to extract it from the database
i have ued the following code
myConnection = new SqlConnection(strConn);
const string SQL = "SELECT TOP 1 PDF_FILE FROM dbo.pdffile";
SqlCommand myCommand = new SqlCommand(SQL, myConnection);
myConnection.Open();
SqlDataReader myReader = myCommand.ExecuteReader();
if (myReader.Read())
{
Response.BinaryWrite((byte[])myReader["PDF_FILE"]);
}
myReader.Close();
myConnection.Close();
while debgugging i checked that ((byte[])myReader["PDF_FILE"]) gets values but the end result is alwz blank

Use while instead if condition:
while(myReader.Read())
{
Response.BinaryWrite((byte[])myReader["PDF_FILE"]);
}

That won't help him, he's got the data in a blob, so looping through the db reader is only going to advance records in his dataset.

hi one way is u keep a button make it style display =none and in the click event u write the code which has to be executed when it is click.and the other thing is simple just call the button click event through javascript where ever u want .eb:document.getelementbyid('button').click();
|
|
|
|
|
Just handle one of the events for the input control such as onblur or onkeypress.

Look at the autocomplete extender

You can use AutoCompleteExtender ajax control
Also u can have a webservice to fetch the records from the DB
it has "ServicePath" attribute where u provide the path of the WebService
and "ServiceMethod" attribute takes the webmethod name which fetches the value from DB and displays
it so u don't have to worry about handling blur events etc..

Hi,
I have an xml which looks like..
<nameid>1
<nameID>hi</nameID>
<nameID>bye</nameID>
<nameID>go</nameID>
<nameID>away</nameID>
<nameID>87687</nameID>
and the above needs to be changed to
<nameID>1</nameID>
<message>hi</message>
<action>bye</action>
<moreaction>go</moreaction>
<source>away</source>
<number>87687</number>
and the first xml which needs to be convert is very huge please let me know any feasible solution...
|

You're pretty much stuck. If the XML is organised into groups of nodes, such as;
<test>
<nameID></nameID>
....
</test>
Then you could write something to rename nodes 2 - 6 in each grouping. If the entire document though is nameID nodes, you're either going to have to through it all by hand and set the nodes up (not like a search and replace will help you) or you're going to have to add some organisation so that you can perform something similar to my first suggestion.

hi guys,
thanks for advance.
I'd like to do something as Google translate, but is more simple than google translate, and is somehow like an online webproxy. it should contain the following function descriptions:
1. get all text nodes from a web page
2. do some changes to the text nodes which is the result of the first step
3. put the changes back to original web page
4. display the changed web page again.
for example, i do some change to www.bing.com, i'd like to do things as follow:
1. get the webcontent of www.bing.com with WebRequest, let's assume the result is as below:
<html>
...
<body>
<span>WebPage</span>
<span>Pictures</span>
.....
<img src="/aa.gif" />
<input type="text" />
<input type="submit" value="Search" />
</body>
</html>
2.changed web page content is as below:
<html>
...
<body>
<span>MyTranslatedWebPage</span>
<span>MyTranslatedPictures</span>
.....
<img src="http://www.bing.com/aa.gif" />
<input type="text" />
<input type="submit" value="Search" />
</body>
</html>
could anybody give me some inputs according the descriptions above? thanks in advance!

Hi xianlong,
maybe you should take a look into HttpModules. You can find many articles here on codeproject on that topic. You can alter the result stream (your html code for example) in this module just like the way you want with the proxy.

Thanks Jens, the question i meet now is how to alter the result stream/ string. that is how to alter the relative path of the website to a absolute path, for example, when the code is
<img src="./a.gif" />, <a href="./default.aspx">Home</a>
good
how i alter them to
<img src="http://www.example.com/a.gif" />, <a href="http://www.example.com/default.aspx">Default</a>
better
and how to get the word "Home" and "good", and alter them to "Default" and "better"
is there any example code you know? thanks again jens!

Dear xianlong,
i assume you have a couple of rules, for example how to translate a link or a specific string. So you have to replace the link and words in the stream according to the rules you have made. For example you translate all addresses in the output stream by replacing the '.' with htt://www.example.com. To do so i would suggest to use reguar expressions. Using RegEx you can get a set of matches and do the same translations for each of the matches.
Since you have different tasks (relative path to absolute paths and translations of specific words) i would also suggest to use a different httpmodule for each of them.
Im afraid i cant give you any real examples to use since i dont know all the details of you task. But replacements can be achieved quite easily using regular expressions.
Regards
Jens
