Can you please post your connectionstring and what database do you use (maybe SQL-Server Express 2005?).
|
|
|
|
|
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="con" connectionString="Server=.\\sqlexpress;Integrated Security=true; Initial Catalog=AdSertrack_WinPrj;User Instance=false;"/>
</connectionStrings>
</configuration>
|
|
|
|
|
Try server=.\SQLExpress. (only one \)
|
|
|
|
|
|
No problem.
And if I may say so, its not the best way to execute sql-queries directly in your UI.

I am trying to create a Tabbed List Box in a web page. I have done it in a windows application and it worked perfectly, but I can't find one little tiny piece of information and need some help.
I am trying to use SendMessage with the ListBox and all the examples I see say to use this:
SendMessage(List1.hWnd, LB_SETTABSTOPS, ListBoxTabs.Length, ref ListBoxTabs[0]);
However! There is no hWnd property for the ListBox control. In the windows app it's List1.Handle, however, there is no such property for that in the web control either! Can someone explain to me how to find the hWnd property of a web ListBox?
Thanks in advance for any help you can give.

There isn't one. You need to spend some time reading up on how to create server controls for ASP.NET before proceeding.

Then why are there examples showing that there is?

You are most likely confused. Show these sources.

try this one it shows exactly what I was saying among others...

Yes, you are very confused.
One, this is for a Windows application. As we have told you SendMessage is not available in ASP.NET.
Two, you are using VB

You're absolutely right! You ARE only two letters away from being an asset!

Or this one....

If you don't have anything helpful or constructive to contribute, then why contribute at all?

Again, Windows, not ASP.NET.
Seriously, stop what you are doing and start reading up on ASP.NET.

Because you are told you don't understand a topic and are given the advice to study it, you vote 1? Very mature. If it was not you, then the same goes for whomever did. At least identify yourself and accept the responsibility to explain why.

The ASP.NET ListBox Server control is completely different from its Windows counterpart. It is just a wrapper over HTML Select tag. Much of what you can do with windows listbox cannot be done with ASP.NET list box. Get yourself a good book on ASP.NET, you may be able to find what you are trying to achieve.

Im trying to limit the scope of active firectory searches
Searching for users and groups, this code works fine;
String[] properties = { "objectGUID", "sAMAccountName", "displayName", "mail", "member" };
String filter = "(| (objectClass=group) (objectClass=user) )";
DirectorySearcher searcher = null;
try
{
DirectoryEntry de = new DirectoryEntry("LDAP://DC=MyCompany,DC=com");
searcher = new DirectorySearcher(filter, properties);
searcher.SearchRoot = de;
// For a directory synchronization search search scope must be subtree
searcher.SearchScope = SearchScope.Subtree;
searcher.Sort = new SortOption("name", SortDirection.Ascending);
searcher.DirectorySynchronization = new DirectorySynchronization();
// Do the search - results should be all groups and users
SearchResultCollection results = searcher.FindAll();
//For brevity display results in small worker
displayResults(results);
// Results are disposed explicitly
results.Dispose();
}
catch(Exception e)
{
Console.WriteLine(e.Message);
}
BUT, if i try to start the search from within the tree, I get "COM Exception, access denied"
DirectoryEntry de = new DirectoryEntry("LDAP://OU=Sales,DC=MyCompany,DC=com");
I see examples with "OU=MyOrgUnit" all over - but I cant get it to work.
However, a DirectoryEntry works with the OU= in the root path
Any insight is greatly appreciated

This is considered rude. If anyone has the answer they will respond in their own time and at their own convenience.

I am facing a issue with the IIS on Windocs XP Pro SP3. I installed the IIS and checked that IIS and web services are up. Then I tried to access the http://localhost page but I am unable to see the page and getting HTTP error 404. I checked that I have file "C:\Inetpub\wwwroot\iisstart.asp" with correct permissions. I have read so may help on web but none is working for me  Actully my main problem is to run the CGI application using IIS. When I try to run any of CGI application on my PC I am getting the error "The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:". Same application is running on other PC with same IIS setup. Kindly share your experience regarding the same. Thanks in Advance.

First, when posting code here you need to use the pre tags to format it properly.
Have you tried Process.Start[^] rather than ShellExecute?
