I have not used that specific captcha technique I mentioned, but I do use ImageMagick (IM) with ASP.NET. I have a pretty basic article on COde Project about generating previews from uploaded images with IM, Using ImageMagick to Create Previews and Thumbnails from Uploaded Images[^]. This is similar to what you are trying to do by creating a dynamic image and return it to the browser. The key method is CallImageMagick(string fileArgs). You pass your argument, such as the captcha command, which defines the distortions and the output path of the file. The random string used to create the captcha using IM would be stored and used to verify the user response to the captcha challenge.
IM is easy to download and install. The latest update which I just installed on our server was "ImageMagick-6.6.0-7-Q16-windows-dll.exe". Make sure to check the last install option - "Install ImageMagickObject OLE Control...", so that MagickCMD.exe will be installed. You will need to provide the path to this file in your code; see my article.
There are several other good articles on CodeProject about using IM with ASP.NET. That is where I learned about it.

Gary

Please help me with this assignment.
Use ASP.NET to write a web page with a form for ordering pizza. When loaded, the page should appear as shown in appendix 1. To avoid clutter, use only 3 options for each select element (for example, use only months 07, 08, and 09 for the expiry date). Be sure to preserve alignment of items. The Submit button sends all the user inputs to URL http://www.pizzapronto.com/orders. The Reset button resets the form.

hi iam using asp.net with c#
in my gridview 1st column is checkbox control

() biscuits 345 89 345*89
() choclate 670 45 670*45
=======
when user click next button then which ever row is checked then data is transfer to other page and displayed in gridview
please can you give some example for this ...
|

Hi, you can create a temp table to insert the Selected Rows and when you redirect to the other page
select thoses rows for Db and put them in the datatable to be a datasource for the GridView.
Good luck

You can maintain the data in DataTable or Collection. Assign the values to the Session object and retrieve it in the next page.

when user enters quantity automatically in total colum total is displayed
please can you give some example for this ...

Uhm.. maybe you can calculate the Total in advanced before you databind to the Grid View.
Or you can use a nested foreach loop for each row and cell and extract the value then do the calculations and assign that in the Total Column.

You could do it on the client-side with jQuery and save a lot of server-side processing and roundtrips. It would be easy to attach an event listener to the checkbox and total all the item's subtotals, etc. Here is a link to an example that updates the total the items in the order table as you add and remove items. It doesn't use Web Forms, but just as easily could: Interactive Form Functionality on the Client-Side Using jQuery[^]. There is a working example at http://altweb.lazerinc.com/jquery/order_dev.htm[^].

I'm using Forms Authentication in my website and i have denied access to anonymous users to a certain folder in the website. I'm using a File Upload in the restricted area and after the user logs in and tries to upload any file to the server, he user is always automatically redirected to the login page instead of uploading the file!!!!
Any ideas how i can avoid this and allow logged in users to upload files directly??!!! Any idea why this happens in the first place?!
|
|
|
|

Just noticed another surprise!! i added login status and login name controls to the login page and i found out that the user is still logged in while the page is redirected to the login!!!
Also noted that the return URl points to the fileupload page. so anybody knows what could possibly be going wrong?!!

Dear All,
I have a query in SQL 2005 which takes some time to complete during query executation I want to show the progress for the user in asp.net application.
I can show Progress bar and I can run the progress of query in the background using thread but the problem exists how can i show the progress based on the query execuation?
any ideas? "I think the better approach would be to show seperate dialogbox (Window) from javascript and show the progress at that window."

Thanks for reply, well the progress is different its based on column selection, the much the colums the much time it takes.It takes less and more than 30 sec in some circumstances.

The challenge of a progress bar as you noted, server-or client-side, is difficulty of what to base the increment on during the query. Building on the suggestion of the first reply, how an animated gif image that symbolizes the query is running, combined with a counter that increments in seconds as the process running. Also, a message that warns searches could take from X - Y seconds, just so they don't think it's locked up. Those three elements might make the wait more bearable for the user.
Regards,
Gary
