Is it possible to loop through a database and display the names of all the tables? If so, please point me in the right direction.

AJAX install question

I am trying to modify a webpage that includes the AJAX tools, but can not get AJAX installed. I have followed the steps using the Sample Web Site, but when I get to the point of adding the tool to the VS toolbar I get an error. “error loading types from Assembly…” “ Could not load file or assembly ‘System.Web.Extension…’ or one of its dependencies. The system could not find the file specified.”
I have VS 2005 Standard edition and have reinstalled ASP.NET.

Any idea what I might be doing wrong?

Handling web service exceptions

Hi,

I have a web service and if my web method catches an exception I then throw a new exception which is passed back to my calling application. Unfortunately though my exception has text XXXXXXX, it gets a load of other stuff added like this:

"System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: ..."

It looks like I'm getting the inner exception trace.

How can I avoid this?

Thanks Smile | :)

Session is a Sever object not client, so you cannot access it in javascript code. You have to pass the string to the server either through querystring or through any form field and then get it on the server and add it to the session

What are you really trying to do? You are in ASP.NET forum which means you have an idea how web forms works. So basically you add a ASP:Button in you page and onclientclick you call the javascript function, in that function you change the value of any hidden field or regular textbox and submit the form. And on server side you add the click handler to the button and in that eevnt handler you get the value of that field.

Please go through quickstart tutorials[^] to understand the whole flow.

e.g. you will call the following javascript function onclicentclick of the button:

<br />
function TestOne()<br />
{<br />
// stringOne is asp:hidden field<br />
document.myform.stringOne.value = 'stringOne';<br />
docuemt.myform.submit();<br />
}<br />

and on server side in event handler for click event of button you will do this:

<br />
Session["Test"] = stringOne.Value;<br />

Reading a multiline TextBox

Hi all,

I have a multiline text box . I wan`t the user entered data to be filled in a single column of the table.But since the user can enter more than one line (by pressing enter or wrap i suppose).

It gives me an error that the data would be truncated. How should i enter the entire data in DB?

Also while reading i need to read it as a ordered list..How can we do that?

Any help would be highly appreciated

from the error it you are trying to save data that is larger than the allowed size in database. So either restrict the user to enter data for allowed size or increase the size in database.

what you mean by "you want to read it as ordered list"?

encrypt strings within web.config

I have read a couple articles on how to encrypt portions of the web.config via command line, but is there any way to do something simillar when console/command line access is not available? such as in a hosted environment? I could possible make a request to the company hosting my asp.Net 2.0 site, but I thought that I had viewed a tutorial some time back where someone did it programatically.

P.S. Let me say to anyone that has noticed that this is my third quest for help this morning... I am new to this forum and promise to contribute back to the forum by helping others where I can. 8-)

posting to confirmation page

I am using the onClick event to send an email using System.Net.Mail.
It works great. If I add a 'PostBackURL' to the asp button on my form to point to a confirmation page, that works but it breaks the sending of my email.
Is there a way, within my C# code behind, that I can send the user to the confirmation page after the mail sending?

I was entering a blog entry in one of our company's web apps, and I got this error when I submitted the post:

A potentially dangerous Request.Form value was detected from the client (_ctl0:cph_Main:_ctl0:_ctl0:postBackBody="...refighter.<br/>
<br/>
Well, ...").

Has anyone every seen anything like this before?

I deleted the text I thought was creating the problem, because it doesn't seem to matter what I put in there.

Yeah. If the user entry the HTML tag in your page, you will get this error..

You can read No.6 as below from my post Some FAQ from ASP.NET web development.

6. Protecting an ASP.NET page against malicious input with ValidateRequest (A potentially dangerous Request.Form value was detected)

When your project is in testing state, you should try to test your application by entering script tag (eg: <script lanague=”javascript”>) or HTML tag (eg: <html><strong>) or #@ or @# characters. And see what happen.. You may probably get the error.. If you don’t wanna get this error then you have to set the page directive validateRequest to false. Note that your page might has the security problem.

Hope it helps..

It may be that your post included tag symbols < and/or > which are, as the error said, "potentialy dangerous". Try removing them, or replacing with < and > and try again...

You can prevent this by adding a
ValidateRequest="False"
page directive but you should only do this if you trust anyone who is able to post to this page, or else parse their input very carefully...

The post itself doesn't have any tags or formatting inlcuded by me, but it appears as if the javascript editor that the blog code uses adds the tags as I type. I'm not going to set the ValidateRequest to false (for obvious reasons, but I may have to recommend that we find a different editor.

It's easy to get paranoid about this sort of thing, but after all these CP forums use just such an editor - allowing html tags to be posted back to the server - and AFAIK the world hasn't ended... yet!
