• Visual Studio Express Editions How to add Help Balloons to the application

  Hi, I have set the Help Button Property on a form to true. This adds a question button to the form. If I then run the project and click the qustion mark button the move the mouse the question mark follows the mouse pointer to allow me to click on a control to then display help on the control. My question is how do I code this so when I click on a control it displays help either in the form of a balloon or dialog. Can not seem to find any help on this subject.

• SQL Server Windows and Forms Authentication issues

  I have a user who is trying to access the SQL 2005 server with 2 seperate accounts(using Windows Authentication).  With one account he can connect just fine, but with the seccond he recieves a logon fail error.  The only difference that we can tell is that the first account uses a password for our kerberos domain, and the second (that fails) uses a longer pass phrase (which does use spaces as characters).  My intuition tells me that shouldn't matter, but I've been wrong before.  Can anyone confirm this, or correct me if I'm wrong   This is using ASP.NET 2005 for the front end.  The exact Exception details are: "System.Data.SqlClient.SqlException: Login failed for user 'domain\user "  The stack tra ...Show All

• Silverlight (formerly WPF/E) XAML caching issues

  Whenever I change the contents of a WPFE XAML file I have to delete the previously cached file from the Temporary Internet Files directory in order to see the change reflected in the browser. Is this a known issue I’m using IE 7, but Firefox seem to have the same problem. Any comments on this would be greatly appreciated! Thanks a lot! /Billy PS: For debugging purposes, I attempted to write a console app that would automatically remove all the XAML files in the Temporary Internet Files directory upon recompiling my solution. However, since that directory isn’t an actual directory but rather an “illusion” provided by the Windows shell, this is not an easy thing to do. I'm having the same proble ...Show All

• SQL Server Distincts databases on the same stored procedure

  Hi!     I need to use two distincts databases on the same stored procedure. One, database1, is where I want to place the procedure, and where the table the procedure populates is (table1). The other, database2, hosts the table (table2) from where I select some data to put into table1 in database1.     Database1 name is fixed, while database2 name may change. So, I would like to pass database2 name as a parameter to the procedure. In this simple example, it works fine: use database1 go create procedure teste @db_name varchar(10) as exec ('select * from ' + @db_name + '.dbo.table2')     But the problem is that in my procedure, database2 is used in a cursor, something like this: create ...Show All

• .NET Development SerialPort DataReceived Timeout?

  I'd like to get better control over when DataReceived are generated while using System.IO.Ports.SerialPort. In particular, I want to be able to control the timeout behavior. This can be done using SetCommTimeouts() when writing to the Win32 API but so far I have not found anything equivalent under .NET Anyone know how this might be done I was thinking I might be able to control it using IOCTL_SERIAL_SET_TIMEOUT but have not been able to find a way to access the underlying filehandle. Is there a way Try setting the ReadTimeout property (it calls SetCommTimeouts), then call SerialPort.BaseStream.BeginRead(). That starts the overlapped I/O and returns an IAsyncResult. You can use its WaitHandle property i ...Show All

• Windows Forms Customizing DataGridView Selection Behavior

  I'm currently trying to use a datagridview to allow the user to select multiple items from a table. While the multiselect functionality will work for what I want. I would prefer to have the program only change the selection of the current cell when a cell is clicked. Or to basically have the program act as if the user was always holding down the Ctrl key for selection purposes. Additionally, I would prefer if I could also restrict selection based upon the value in the cell being selected. Looking around the net, I found vague references to being able to disable the ordinary selection behavior. However I have not been able to find any information on how to actually do this. If anyone knows how to do this, could they point me in ...Show All

• SQL Server Support for NVARCHAR(MAX) and VARBINARY(MAX)

  It would be nice if SQL Server Everywhere could support NVARCHAR(MAX) and VARBINARY(MAX), even if they would just be alias' for NTEXT and IMAGE. This would somewhat simplify the interoperability with SQL Server 2005 (i.e. no need to have different scripts for each database type). Gerrit Thanks for the suggestion and I will take it forward and let me say what they say. However, here are my points on the problem which you have mentioned: This is NOT the ONLY difference for T-SQL between SQL Server and SQL Server CE. So, just fixing this does not really make your T-SQL script portable. If it has to be portable then you are expected to use what is supported by SQL Server CE and SQL Server both. So I rec ...Show All

• Visual Basic A Squigley

  Why is there a squigley under the Ex It's only under the first the message reads Unused Local Variable:'ex' Catch ex As Exception 'handles any errors MessageBox.Show(ex.Message, "PGS", _ MessageBoxButtons.OK, MessageBoxIcon.Information) I tried your snippet and I still didn't get the squigglies on the 2 locations that you mention. I did made some changes to get the code to compile but I don't think that it would make a difference. Anyway, the squigglies that you see are compiler warnings. Their main purpose is to inform you of potentially problematic or inefficient situations. Because they are only warnings your code still compiles and executes just fine. If you f ...Show All

• Windows Forms Problem with DataGridView autoscroll. Please help.

  Greetings, Could someone plese help me on this issue. I'm a junior developer and have been struggling on this for quite some time now. The problem I have is that I have a DataGridView. Inside the DataGridView I have a number of rows. The DataGridView is placed inside a Panel. The Panel's autoscroll preoperty is set to true. The DataGridView's autosize property is set to true. At the moment the DataGridView has enough rows to have the Parent Panel scroll up and down. But there's a problem. Each time I click on a cell to edit it the ScrollBar scrolls automatically. I know this has to do the the CurrentCell thing allowing for the autoscroll to take effect. But how can I prevent this Is there a way to do this Any help will be appreciated. Tha ...Show All
