I installed vs2003.net on sbs2003 with IIS6 (.net framework 1.1) I created my first app, put a label on webform1 and run the project (debug)
1 - messagebox: "Error while trying to run project: unable to start debugging on the web server. The project is not configured to be debugged (I did a lot of searching, found tons of so-called solutions, but neither works)
2 - run the project from the menu Start without debugging. I got a server-error: <authentication mode = Windows in web.config)
Two questions:
a. when the app runs under VS.2003 it uses IIS ?
b. if not, why doesnot run the app ? if so, which website it uses in the IIS-manager (is that the Default website or other ?). What happens when I delete all the websites in IIS-manager and run the app in VS2003 ?
i can't debug the code line by line code, i have break point in form load event, but it skipthe breakpoint , can't able to debug.

View 1 RepliesIn VWD, we can customize-edit-command to your heart's content. But there is none for what I used to get in NetBeans or Eclipse: go to the last edited position (after 5 minutes of search for the correct spelling of some name in the page).I know there is Navigate Back, but I often need to do click [Navigate Back] 10 times to get to 'last edited line'.
It would be nice if I can navigate through the 'green bars' (Yes, it is very difficult to find out what are green bars, once you found out, you want to be able to visit each of these using next or prev).
Also where is the documentation or help ofr each of the some 50 edit commands such as 'go to Reference'.
I am having an issue in VS 2010 trying to get even the default ASP.NET Web Application to run in Debug mode. I get the error:
"Unable to start program 'http://localhost:1443/Default.aspx'.
The system cannot find the file specified."
I am stumped here and cannot find anything out there with this error.
i notice that when i start next line of code and i press enter, it recompacts itself and the continued line moves left a bit... then if i place focus on the second line and press enter again, it (the second line) moves to the left some more, and it keeps doing this every time i focus on second line and press enter. this is as you can imagine, really annoying!!
how can i make it so that my second (and third etc) lines are formatted in a pre-determined way so they are always a certain amount of tabs indented to the right from where my line 1 starts??
Many times I remove in the code window (Using Replace and Regular Expression). Is ther a quicker way of doing this without writing a macro? The best way would be a shortcut key.
View 2 RepliesI m looking for a Shortcut to :Delete currentline and below lines 1 line upward.
currently Ctrl+X (without selection) does this.But it also removes clipboard to empty text.
isnt there a shortcut Just deletes current line and 1 line upward next lines without clearing Clipboard ?
I want to get the line number of my code -- not in case of an exception though. Is there a way to capture this?

How do I build a web application project from command line using Web Developer Express 2010?
I am using the same command format that I would use with devenv.exe (Visual Studio), so I can evaluate us moving forward to VS2010. However, I am having real trouble building our code. Our solution consists of 4-5 projects, consisting of assemblies. The last assembly is the web site code. The root .sln file is the one which when opening in the IDE can click Rebuild All, and the DLL's of each project are generated and then brought into the website project.
However, when I run vwdexpress.exe from the command line nothing happens and no Dlls are generated. This is not giving me any confidence to run with VS2010.
the command line is like so:
C:inetpubwwwrootmyprojectvwdexpress /build release mysolution.sln
The in folders of each respective project are empty, but it takes 3-4 seconds for the command to finish, which gives me the impression it did something.
In Windows XP, I used the following command line to tie a particular website to a particular version of .Net Framework:
C:WindowsMicrosoft.NetFrameworkv2.0.50727 aspnet_regiis -s w3svc/1/root/sdcrrlf (sdcrrlf is the website and is written in ASP.NET 2.0; hence uses v2.0.50727; some other of my sites use V1.1.4322)
This command line does not work in Windows 7 with IIS 7.0; error message says path is incorrect.
We need through command line to build our site (which we already do using msbuild.exe), but the resulting files are way too many and it takes our to ftp it to the server. I am able to publish the website and reduce its size by ~90%; however, we need to do this through command line not manually using the GUI. I have read many postings but noone is clear on how to do it (and msbuild seems to no be able to do this). Can anyone provide me a link. We are using Visual Studio 2010 and DOT NET4.0
View 3 RepliesJust wondering if it is possible to set it so that when you have too many files open in Visual Studio, rather than display the little down arrow icon, it drops the tabs down onto another line?
View 5 Replies I just installed Visual studio 2010 ultimate RC on my windows 7 server. It doe snot show line number. So I went to Tool->Option->Editor, however, there is no where I cna find line number choice.
I used to have Visual Studio 2010 professional beta, it has the same problem, no line number to show up. However, it has a check box: line number. Even if I check the box, still no line number to show up.
I am getting the following error when I try to establish ftp remote connection using the 'copy web site' feature on visual studio 2005.
unable to open the web 'ftp://209.*.*.*/httpdocs'. The computer is disconnected from the network.
Why can't I connect to the remote site on visual studio 2005? I can do the same thing on Dreamweaver with no problem. I can ping the IP successfully. I can open the ftp URL on a web browser with no problem.

I am using the ASP Web Application template from Visual Studio for my website. I created an images folder in the directory directly, and not in visual studio. I cannot get visual studio to show this directory. How do you add directories in visual studio or get it to recognize it. I know most of you are thinking of responding with "Why don't you just create the image directory through visual studio".
