I believe you configure that in IIS.

Step 1 : Run > type inetmgr

if IIS is installed in your system the IIS will open UP otherwise you have to install IIS from Control Panel > Add Remove Program

Step 2 : In the Explorer side, you have a web site folder. If you click that folder, "Default Web Site" Will be there. And its by default runs on Port 80.
And any Virtual Directory created under that default site will run on port 80.

Suppose You have a a virtual directory called "MySites", you can access then like
http://servername/MySites
or
http://servername:80/MySites

Now : You want to create another web sites Say "My Web Site Two" , you can create, but you have to change the Port Number by Right Clicking on Web Site -> Properties TAB > Web Sites

Hope this gives you clear idea.

Let me know if any issue.

webrequest POST not creating the right response

Exeter331-Mar-09 19:33

31-Mar-09 19:33

I am trying to automatically populate a forum control on an asp page.

I am send a webrequest with POST and url encoding. However, I always just get the empty form page back.
Sending the data on the URL using the "data1=val1&data2=val2" just brings up the form itself as well.

I starting to think I am missing something. The site uses __doPostBack in the form. I will have to maintain cookies and state on any subsequent calls, but the first one already fails.

How can I tell which type of request the page accepts?

Thanks for your help.

I want a suggestion on the following example :

Is it better to throw custom exception from an method which checks before inserting employee detail that particular employee's email already registered and catch that exception in my aspx.cs page or say view layer.

or

return error Number, something like -999 if duplicate email found.

from a method and then use conditional statement.

If nothing gets returned you need to debug your SQL. Otherwise, you may just need to write a MIME type. Spend some time in the debugger, and get back to us when you can tell us what is specifically happening.

Apparently, you don't have access to that file. Perhaps you might consider telling us what code causes this error, and when it happens. Saying 'I upload the file' doesn't tell us much. Did you try to upload a new file to your images folder and then access it ? How did you try to access it ?

if you r using Ajax u need to give trigger tag for that upload control.
otherwise change that file('D:\aesweb\WebSite\Images\banner_bulb.gif) property readonly false.

It may be cause of user does not have the write permission on that folder.
Possible Solution :
1. Give the write access to that folder.
2. [If you have deployed it in IIS] Create a separate application pool, change its identity of local system, assign that application to your virtual directory.

Your problem will be resolved.

This has nothing to do with ASP.NET, even though you're doing it within the context of an ASP.NET site. You're modifying a local Excel file, you'd do better to ask in the right forum for the language you're using.

Type or namespace not found for user control.

Brady Kelly31-Mar-09 9:53

Tonight I copied an ASP 2.0 web site onto a client's machine, and lo! It did not work. It works perfectly on mine, under built in debugger and under IIS 7, and two weeks ago, it worked perfectly on his machine under IIS 6.

The only changes I have made are upgrading telerik RadGrid etc. to Q1 2009, and some refactoring. The application fails on two entry point web forms. Both have a RadGrid, which uses a User Control for its editing pop-up. Both forms fail to compile, with a 'Type or namespace JobEditControl not found" error, on a line like this:

var editControl = e.Item.FindControl(GridEditFormItem.EditFormUserControlID) as JobEditControl;

The control is not referenced in the markup, as it never appears on there, and as I understand it, it should be compiled into the same default namespace as the page is compiled into when first hot.

The machine is still serving user controls properly, i.e. the .ascx handler appears healthy, and a quick test page containing a quick test control I added worked fine.

Another developer was busy on the machine before me, also installing an ASP.NET application, but I can't think of anything he would have changed. Even being my competition...

i have some hyperlinks on a form.I have set the navigate url of all the hyperlinks to a single destination page("display.aspx")i.e.clicking on ne of the hyperlinks would take you to the same page "display.aspx"..
but based on which hyperlink i hav selected, accordingly values from database will be retrieved and will displayed in "display.aspx"..
for eg:
suppose i hav 3 hyperlinks say :
1)programmer
2)business analyst
3)software engineer

and if i click on programmer then accordingly query will be executed in the page load event of "display.aspx" and info abt programmer will be retrieved from database and displayed in a gridview.
plzz suggest some solution..

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
