Hi,
i'm a .NET newbie and hope someone can help me. I try to build something like an applet (Java) with C# and .NET. I've been told this can be done by a windows forms control assembly embedded in a html page via the well known <object> tag. Indeed, everything works fine except the control's database access to a local database. Here i get the exception "SQLClientPermission denied". I'm sure the problem lies in the CLR access policies for the code of the embedded control (coming from the intranet zone). Can anyone tell me how to grant this SQLClientPermission to the code of my control?
Thanks for your help,
Fridtjof

This is what I do to prevent duplicates on my site (non-cart oriented)
1) Create a field in the table that stores a unique id with each submitted item. Create a unique index on the field.
2) Generate a unique id (if you're using php, generate an md5 digest, and use the first 10 or so chars) when the form is displayed, and store its value in a hidden input field in the form
3) When the form is submitted, add the unique id to the table along with the rest of the data. If the user goes back and hits submit again or hits refresh, reinserting the unique id will bring up a duplicate key error, which you can interpret as "you've already submitted your data".
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

I think ur basic purpose is that user should not be able to submit twice.
Now if that is the case then in the db table with which the forms fields are concerend(In which submit button is) u can have a field status which can have two values(Yes, No).When form is submitted then status value should be Yes otherwise No.
On every submission u can check the value of status by a query.If it is Yes then U can show an error msg otherwise can accept the values.
I hope this will serve ur purpose.

NO.
You can access the varibales of the other form using javascript but action will take your page to only one url.
Code below:
Here u will be redirted to test1.html
|
|
|
|
|
So, you mean each HTML page can have one or more forms, but more than one form can not be submitted at one time, right?
Thank you, man!

Hi,
i want to embed a signed windows forms control (assembly with strong name, using a .snk key pair) into a html page. Using the normal <object>-tag works fine with the unsigned control, but doesn't work with the signed one! The signed control doesn't even open! In both cases i used the same html code. Is there information missing (e.g. about the key pair)?
Thanks a lot for your help!

Hi,
here some additional informations:
1. I used sn -k key.snk for generating the key pair.
2. Then I used an attribute in the AssembyInfo.cs file to sign the control:
[assembly: AssemblyKeyFile("key.snk")]
3. In the html page the code
<object id="A" classid="http:ALib.dll#ALib.MyACtl"
width="568" height="416">
</object>
worked fine with the unsigned control. I used exactly the same code with the encrypted control. It seems to me that Internet Explorer cannot find the class "ALib.MyACtl" any more. Maybe since it is encrypted now???
Thanks for any advice,
Fridtjof

I am developing a website that uses the same images on some secure and unsecure pages. I know I can't keep the secure images in the cache so I have to load them every time I link to a new secure page. I have a javascript that loads the images in the head section of the secure pages. It seems to work on Internet Explorer on Windows but other browsers/platforms are only displaying the first image. Does anyone know what might cause this problem?
Also, is anyone aware of a better way to keep secure images around(i.e. in the cache) or a way of tricking the browser into thinking that my previously cached unsecure images are actually secure, without getting the annoying popups about secure and unsecure items.

One thing you may want to try is using the following code in your page:
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
This should trickle down to the images as well, but don't quote me on it.
