I have an aspx page that loads a static graphic and put session strings in it. I used Image1.Save(Server.MapPath("gen_img2.jpg"), ImageFormat.Jpeg), but it's not saved on the server. I thought this was a user permission problem, so I assigned the ASPNET account write permission to the folder, and it still doesn't work. Did I use the wrong account? I use winserver 2003 and IIS 6.

How to print barcode
provide me sample code for me ASAP.
I have two scripts inside my webpage
<script type="text/javascript" src="http://somesite/somefile.js"></script> <script type="text/javascript" >somecode('a','1z4j73');</script>
This script is generating a visitor map on my web page, now I don't want my user to click on the script and get redirect to that website. How can I restrict that? Can I make a div tag and make all element inside the div tag to read only? I have make sure that this restriction doesn't falls under company rules, they just want their logo under the map. Can I catch this through any event and again redirect the user to the default page? Like when user click the image, I check the URL and if the URL contains that site name I again redirect to the default page.
I have one ogoing thread [URL]. IN addition to this thread I would like to insert image in newly generated word document. My problem here I can give our hosted server path using Img Source property. I want to copy or embed the imaged in the word document.
Let me know what is the best way to do it using asp.net/C#.
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
View 2 RepliesI have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

I have a text field into which I'm saving order details, using LINQ to SQL.
Each order may have a different number of columns, depending on the type of order, so I thought I'd just create a single structure to take care of everything, and display details in tab delimited columns.
The text is created properly prior to saving to database:

However, when stored in the database, the spacing is no longer maintained.
