Hello, I am having a problem that I believe is related to the way a stream reader object looks for a text file by default. What I am doing is using a StreamReader object to read the text of a text file which includes some html code to populate html formatted content as the text of an asp:label (<asp:label>). The reading of the text file itself goes just fine ;however, this only occurs when I use an absolute file path which will not work of course once I upload the website to a hosting service. The text file is in the same directory as both the .aspx file and the codebehind the page file in the Website directory in the Visual Studio 2005 directory structure located in "My Documents". Here is the error message that I receive when I attempt to create load the page without an absolute file path to the text file in the StreamReader object: - Could not find file 'C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\Default4.txt'.
-

Here is the code located in the text file named Default4.txt: - <br /><p align=right>Hello There World!!</p>
And finally here is the file path that I must use in the StreamReader object in order to avoid generating an error: - C:\\Documents and Settings\\Main\\My Documents\\Visual Studio 2005\\WebSites\\WebSite2\\
Is what is going on unfixable? Also could someone experienced with uploading Visual Web Developer 2005 generated sites give me a few pointers on deploying them? Any help here would be greatly appreciated.

While assigning the file name, you have to provide it with the path of the file too.
If you do not, then it will map it from the default path.
What you need to do is to map it from the servers path, so that it will navigate from the application folder.
User server.Mappath to get the desired path. and then supply it to the stream reader.

Hi,
I'm fairly new to ASP.Net. I have Visual Web Developer 2005 Express.
Except for the default.aspx, whenever I create a new Web form, no code
behind (aspx.vb) page is created. The same thing is happening for
master pages.
I have exited Visual Web Developer 2005 Express and restarted it, and I
have rebooted the PC, but the problem persists.

Realizing that I did not need Visual Web Developer Express 2005 since I had

My question could this be a possible reason that the ASP.NET configuration
tool is not
working in VS 2005 when I am doing web development? What happens is upon
execution
it just brings me back into the same VS design page from where I executed.
