• Windows Forms datagridview rows editable or not

  My datagridview has to have noneditable rows except for the ones that are new. I have set AllowUsersToAddRows true for the grid. This adds a row at the bottom and user can enter the data. I want the new rows to be editable. Also the copy and pasted rows should be editable. So I added a flag to the database . If this flag is 'Y' I want to make those rows noneditable but for the new rows I want to initially set the flag to 'N'. In which datagridview should I set the datagridview.currentrow.Readonly=true; I am a newbie...please help... ...Show All

• SQL Server full, differential, transaction hwo to rotate the differential?

  Being of the "point and click"-generation I managed to create some sort of a fairly simple backup plan for our databases. There are hourly transactional backups and daily full backups, which were set up with a database maintenance plan. As the databases store event records they are ever increasing around the hour. The daily backups are now of a size that holding them is not feasable anymore and I want to move to a differential backup scheme: Weekly full backups Daily differential backups Hourly transactional log backups The problem I have is that the database maintenance plans allow me to rotate backup files automatically as they included the date and time of the backup. For differential backups there is no option ...Show All

• Visual Studio 2008 (Pre-release) ContextMenu as UserControl issues

  I'm using a ContextMenu with a single item to implement a popup editor for some values. Since this shouldn't look exactly like a menu, I need to style the ContextMenu and it's items differently from other Menus and MenuItems in my application. It seemed like the most straightforward way to go about this would be to make a UserControl which contained my ContextMenu. That way I could locally style all of the elements inside my 'PopupMenu' inside the XAML. That fails with an exception since ContextMenu cannot have a logical or visual parent. The next approach was to make my UserControl contain a MenuItem and then place that inside a ContextMenu in my code. That also fails since the MenuItem is already owned by the UserControl. The only ...Show All

• Visual Basic Debugging

  I have tried to access the Command Window while debugging a simple vb program. When I type >cmd In the Immediate window I get the error message "Command "View.CommandWindow" is not valid". The Help file says that I can access the Command Window from the "View \ Other Windows" menu, but my "Other Windows" menu doesn't even list that option! Any help would be appreciated. Thanks. Yes, I am using VB Express. You are probably correct. I am using a book from Microsoft ("Visual basic 2005 Step by Step") and had realized a few other commands are not available (for example, I have only one Watch window, whereas the book mentions the possibility ...Show All

• Visual C# MessageBoxIcon.Hand not working as expected

  I have a MessageBox that I would like to use to advise users that a DataGridView has no records in it that can be modified. I've written the code for the MessageBox to look something like the following... MessageBox .Show( "No records are available for editing." , "No records to modify" , MessageBoxButtons .OK, MessageBoxIcon .Hand); The problem is that the Hand icon does not display when this message box displays. Instead, I get the standard error icon that consists of a white x in the middle of a circular red background. I've noticed that the tooltip that appears while I'm writing my code even tells me that this is what will display. Is this a known bug or am I having this problem for some other rea ...Show All

• Visual C++ VC++ won't run from source control: "The system cannot execute the specified program"

  Hi, I've installed VS 2005 C++ Express into source control and it won't work. I've wasted the better part of a day so far trying to get it to work. The error message I get when trying to run something as simple as lib.exe is: "The system cannot execute the specified program." When I load up the .exe in the dependency walker (depends.exe), it says: Error: The Side-by-Side configuration information in "y:\compilers\Microsoft Visual Studio 8\VC\bin\LIB.EXE" contains errors. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem (14001) .

• Windows Forms FormClosingEvent has no CloseReason

  In a Form I created, I've subscribed to the FormClosingEvent. In this event I want to distinguish between a user that closes the form, or an outside OS event that closes the application. Therefor I read the CloseReason member of the FormClosingEventArgs. However it seems that when the user clicks on the OK button which is the Forms AcceptButton, the CloseReason seems to be set to "None". The same goes for the form's CancelButton. Is this intended behaviour, and if not, should this not be documented When you handle the user clicking a close button that you have created on your form, you probably handle the application close with your own user code with a "this.Close();&quo ...Show All

  I have TestPartner scripts created as tests. I added a test in the 'Lists of Tests' tree. I hit refresh. Test list fails to find the test I added.

• SQL Server OLE Db Source and Variables

  I created a OLE DB Source, and created a sql command text. The issue is with parameters, I have to use the ' ' to identify. What if I have multiple variables of the same type scatter around, how can I define that Somthing like this would be good... Declare @month set @month = select blah,@month where month=@month or How could I use the ADO Syntax and just put @month Thanks, Mardo Guys, my apologies for being a bit misleading. The .NET connection manager can be used in conjunction with the Execute SQL task (in the control flow) - when using this type of connection manager you are able to use named parameters. The OLE DB source adapter (in the data flow) is specifically OLE DB i.e. it must use an OLE DB connection manager to ac ...Show All
