Q: What is LC.EXE?
A: LC.EXE (License Compiler) is a command line utility provided with .Net Framework 2.0. By default this utility is installed in C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin. When executed, LC.exe will read license information from a text file and include it with .Net assembly. For more information, goto http://msdn2.microsoft.com/en-us/library/ha0k3c9f.aspx.
Recently a KB (Knowledge Base) article was published for a bug regading this utility. The License Compiler (Lc.exe) throws an exception when a .NET Framework 2.0 application consumes licensed components on a computer that is running a 64-bit operating system. For more information, see KB article 913961.

Using Shutdown.exe
Q: How can I remotely shutdown a machine in a workgroup?
A: Use the Shutdown.exe command with the –m switch. This command is found in the Windows System directory (i.e. C:\Windows\system32 for Win XP), and will allow you to specify a remote computer name to shutdown. See the following for more info
Usage: shutdown [-i -l -s -r -a] [-f] [-m \\computername] [-t xx] [-c "c
omment"] [-d up:xx:yy]
No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c "comment" Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without war
ning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536)
This can be executed from a script or a .Net program.

Detecting a ClickOnce Application
Q: How do I tell if I'm currently running in the context of a ClickOnce application?
A: You can see if a ClickOnce application is running in the current AppDomain by checking the AppDomain.CurrentDomain.ActivationContext property. If that value is non-null, then the domain is running a ClickOnce application. The ActivationContext will also get you the name of that application. There may be situations (such as choosing an isolated storage scope), where having this information is necessary and useful.

File Upload Limit
Q: I’m using code very similar to that in this article (http://www.dotnetspider.com/technology/kbpages/568.aspx). The problem I have is when I try to upload a 9 MB file, I immediately get “Page cannot be displayed” error. Execution doesn’t even reach the PageLoad() event. The size limit for an IMAGE type in SQL Server 2000 is 2GB+, so size should not be a problem here. When I try the same function for files under 4MB, everything works as expected. What's the problem?
A: Your web application can only upload a file size of 4 MB only. To upload files more than 4mb you have to add option in the web.config file and set the maximum file size there.
In addition, if you're running IIS6, you could be hitting the limit for AspMaxRequestEntityAllowed. If the Content-Length header field of the HTTP request is larger than this limit, the page will bomb out immediately. You can increase the value in IIS6's metabase. For more info, goto
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/iissdk/html/99b8a8bd-f9e7-43a8-b4cf-1186e2b3e9e2.asp

What is _vti_cnf ?
Q: What is _vti_cnf?
A: This is a special folder created by Frontpage for use with IIS. Other folders may include _vti_script, _vti_pvt, or _vti_txt. For a complete list of FrontPage special files and folders, goto http://www.rtr.com/fpsupport/SERK/a_spfile.htm. This folder is not required for an ASP.Net application so it can be deleted manually.

Setting the Default Button in ASP.Net 1.1
Q: I have an ASP.Net 1.1 search form with several buttons on it (Search, Clear, Logoff) and a search word field. Currently, if the user enters text in the "Search Word” fields, and presses ENTER, the logoff button (located on the banner at the top of the form) is activated and the user is prompted if he wants to logoff. How can I change it so the ENTER key will activate the “Search” button instead? In other words, how can I make the “Search” button, the default button?
A: In ASP.Net the enter button executes the first button on the page. So create a button that is not visible (width is set to 1 px) and placed it at the top of the page before the logoff button. Change the background color if needed and make sure it cannot be seen. Then set the click event in .aspx page to execute the search button click event. When the user presses enter, the first button is executed and it will call the search method.

Accessing Version Number in .Net
Q: How do I programatically access the version number of an ASP.Net application?
A: The version number, and other general information, is kept in the AssemblyInfo.vb (for VB.Net projects). All information is housed in attributes in the file, as listed below:
Assembly: AssemblyTitle("MyApp")
Assembly: AssemblyDescription("A Sample Program")
Assembly: AssemblyCompany("ABC Software Corp.")
Assembly: AssemblyProduct("")
Assembly: AssemblyCopyright("2006")
Assembly: AssemblyTrademark("")
Assembly: CLSCompliant(True)
Assembly: AssemblyVersion("2.0.*")
To access the application version through .Net code, use
System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString(). The value displayed will be 4 sets of numbers, separated by '.' (similar to TCP/IP address). The version information for an assembly consists of the following four values:
Major Version
Minor Version
Build Number

MSDN Beta Home Page
One of the tips I give to developers who want to stay up to date on the latest .Net information is to view MSDN web site (http://msdn.microsoft.com) regularly. It's a good idea to set it as your default home page so you can glance the headlines everytime you open a browser.
Expanding on that idea, Microsoft is now working on a Beta MSDN site (http://msdn.microsoft.com/aboutmsdn/betahomepage/default.htm) . The 2 big features of the new site are Country specific content and "My MSDN" for personalized content management.
