• SQL Server Report parameter validation from report manager in reporting services 2005

  Hi, Whenever user viewing a report using report manager, how can we validate the input values from user for a datatime type report parameter. i.e. validating whether the date is correct and in required format. Thanks in Advance. Regards Pintu The built in parameter UI performs only simple validation (making sure a float parameter has numeric characters, for example). The server will perform a full validation on the parameter value for formatting, culture, data type, etc. If you want more advanced client side validation, you will need to provide custom parameter UI in your own portal. Report Manager is not extensib ...Show All

• Visual Studio Express Editions F1 problem

  When I login to my computer as "administrator" the F1 key works perfectly in Visual Basici Express. Then I logout and login a user with admin right. The F1 Key gives a message server cannot be found. Cannot access the Help files under a user login with admin rights How did you install the product As Administrator If you did and do not have administrator privs then I would suspect this is expected behaviour. Might want to try adding your account to the administrators group and see what happens. ...Show All

• Visual Studio Express Editions Selection changed event raised on adding a row to a DataGridView - c# express?

  Hi, I have a form with a Datagridview control which gets filled programatically. It also has an associated 'selection changed' event for when the user gets to interact. In beta 1 all was OK but in beta 2 the selection changed event is raised everytime the program adds a row which is definitely not what I want. Anyone know if this behaviour is by design As a workaround I guess I could disable the selection changed events and then enable them again Which leads on to the Newbie question how do I disable the event which has been set up in the designer section using the properties pane Many thanks for reading Cheers ...Show All

• Visual C# How to determine file reading progress

  I am using streamreader to read lines of text from a file. I would like to indicate on a progress bar the status of the reading process. What would be the best way to determine where I am within the file so that I could divide this number by the filename.Length member to display in my statusBar I'm having trouble finding the right method for indicating where the file pointer is... You don't use Control.Invoke to read the file. You use a different thread to read the file, then Control.Invoke from that other thread to update the UI.

• Visual Studio Express Editions How to import a .DLL at runtime?

  How do I import a library contained within a .DLL file at runtime, given its path Is this even possible in VB.Net 2005 Express Do you mean a managed or unmanaged dll If a managed one you can simply load the Assembly with one of the many load functions provided by the assembly class. If on the other hand you mean an unmanaged dll this gets a little tricky as you would need to know the name of the dll, the name of the function(s) you want to call and their complete signatures at compile time for a proper P/Invoke ... otherwise you are more or less out of luck. ...Show All

• Visual Studio Express Editions Using VB Express with SQL Server Express in a lab

  I'd like to allow students in a lab to use the Express Manager and T-SQL to create their own databases. I think I've figured out just about everything - but the last step. Here's my thinking on how to do this: 1. Students are power users, not local admin 2. Created a login for the builtin\power users group as follows: create login [BUILTIN\Power Users] from windows with default_database=[master] go exec master..sp_addsrvrolemember @loginame = N'BUILTIN\Power Users', @rolename = N'dbcreator' go 3. Now students can start the Express Manager and connect to: localhost\sqlexpress using Windows Authentication 4. After they do, th ...Show All
