I have an ASP page that is the basic 'home' location (called user_area.asp) for all of my clients who log into my website. In the user_area.asp page, it calls for some common elements with an #INCLUDE FILE statement that are standard and not variable. (Such as 'header_inc.asp' and 'footer_inc.asp')
If I have a field in my Cutsomer Data Base (.mdb) called 'Custom2' and that field would contain a URL to something like:
mysite.com / clients / clientname / client.asp
What I would need to do is be able to use the #INCLUDE FILE statement to call for the 'Custom2' field so that I could include the clients 'client.asp' within the 'user_area.asp' page.
This 'Custom2' variable in my database would change accrdingly to whomever logged into the system. Since none of the clients have the same exact download files, the 'Custom2' variable would always change and the #INCLUDE FILE statement would always point and display a seperate client.asp page withing the user_area.asp page.
I'm building a web accounting application in ASP.NET 2.0 using VS 2005 and SQL Express. I already developed a VB6 accounting app but re-developing in ASP.NET 2.0 is a bit difficult.
My problem is in making the form/web page look very much like the actual business form, say a sales invoice. In VB6 I could use the DBGrid control to add data but in ASP.NET 2.0 the GridView can only edit, select or delete. How to Create an Invoice-like Form in ASP NET 2.0 ?
I am at the moment trying to use a FormView for the invoice header so that I can rearrange the textboxes so that it looks like an invoice header (eg. invoice number, date on the right top edge, address on the left top edge, etc)
For the line item details (Stock Code, Description, Qty, Price and Amount) I put another FormView with a row of text boxes and an Insert link at the end and then a GridView just below it so that the columns are aligned with the input text boxes above. When users enter the input in the one-row text boxes above the grid, they can inserted into the grid row by row and the text boxes become blank again to accept new input.
I have tried to use the DetailView control to make my programming easier but I find no way to convert it into one single row rather than what it is now (1 column, a new rows for each field).
MailFormat is an enum that one of his options is "HTML" that sends the email in html format (as you asked) and by using the class MailMessage you can render a html code and send it to the customer..
string customerName = ".....";<br />
long customerId = 539482;<br />
string messege = "<html><body>Hello " + customerName + " your Id is " + customerId.ToString() + "</body></html>";<br />
and then by using the Body property in MailMessage you can set the mail's text to the messege
mailMsg.Body = messege; //assuming mailMsg is the object of MailMessage<br />
I have a contact form in my web site which is working just fine on my

Maybe the error comes from me getting data from Web.Config?
I have this code inside a custom control but here it is:

Anyway, could someone help me out and send me some sugestions?
am using asp.net 1.1 to code the web page and my virtual directory
is pointed to use asp.net 2.0 calss library (client requirement)
Can any one help me with the following error that am getting
"Invalid postback or callback argument. Event validation is enabled using in configuration or in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."
I am generating a high resoulution image on the web server, which should be afterward downloaded onto users machine without displaying it in the browser and requiring user to make a right click and choosing "Save image as..."
Thanks for help, but I actually do not want any user interaction, except for specifying name for data.
When I make response.redirect("myzipfile.zip") and point to a zip file, the dialog for saving data locally appears. This ist what I want to see when I redirect to an image file, istead of displaying it.
To force the Save As dialog box at the client side, you can use the Content-Disposition header field to send the image data from the server to the client side. You can simply google for "ASP.NET Content-Disposition " to get more info.
I´m a really confused about what is the best way to maintain asp.net page state (viewstate, session, profiles):
Nr 1: are all objects destroyed when a page request has finished and returned the html/aspx page? If that’s the case it conveys that I have to re-create all objects when a new request is made and “re-fill” objects with values? Or?
Nr 2: What is the usual way to “save” a users state variables?
For information that needs to tracked across multiple post backs
a) Use View State - If the information is tied to a single page &
If the information consists of fewer bytes
b) Use Profile - If the information represents specific to the logged user on the whole
rather than a page or group of page
c) Use Session - Information that needs to be tracked for the user, that applies to your
application on the whole again use session variables, again you may not want
more than few 100 bytes of information as part of session
d) Database - If you need to track information for ordering of records and if you have few
thousands records always re-request it from the database instead of storing it
in session variables
e) Cache - If information is common across all connected users.
