• Windows Forms form close reason

  Hi! I would like my form to be hidden when the use clicks on the window close button (the X button on the top-right corner). The e.CloseReason does not provide a value to determine that this particular button is the reason that is closing the form. This was very simple in VB6: Private Sub Form_QueryUnload(Cancel As Integer , UnloadMode As Integer )     If UnloadMode = vbFormControlMenu Then         Cancel = True     End If End Sub   How is this possible in .NET Forms Please read this thread: http://forums.microsoft.com/msdn/ShowPost.aspx PostID= ...Show All

• Visual Studio 2008 (Pre-release) LINQ for compiling cool... but what about dynamic queries at runtime?

  just curious how this'll be handled.   having queries directly embedded in the code is awesome from a type safety standpoint, but what about at runtime i assume some kind of "on-demand" Compiling for a program like "SQL Query Analyzer" (more aptly named LINQ Query Analyzer) that is dynamically compiling these LINQ queries and seeing results, kinda like snippet compiler. I bring this up becomes sometimes you gotta give query ability to the users (report generation etc) To add data, create a new object, and add it to the table. Then execute SubmitChanges() on the data context: Code Snip ...Show All

• Visual Studio Check in web service that are already under source control for VS2003

  At this moment we are upgrading web services, that are already under source control, from VS2003 to VS2005.

• Visual Basic Standalone application

  Hi, I am looking to produce a standalone application supplied on a cd, which will be given to sales reps. They in turn will open this program from the cd or their computer. The program will have the facility to choose different powerpoint slides from different powerpoint presentations represented by thumbnails. Some of the powerpoint presentations contain numerous sections with numerous slides in each section, so it would be best if there was a button named “example” for the chosen powerpoint file called “example.ppt”. The button “example” would have a dropdown menu for the sections within “example.ppt,” this when clicked will provide a win ...Show All

• Visual C++ Serial number on usb flash drive.

  I am unable to get the serial number on usb flash drives. It always returns 0 indicating it is not there. I am using DeviceIoControl with IOCTL_GET_DEVICE_DESCRIPTOR to get the venderID, productID, and ProductRevision, but the SerialNumber is always 0. Has anyone run into a similar problem As this question is not specific to Visual C++ you would be better off asking it in one of the Win32 support newsgroups.

• Visual J# List of All J# Browser Controls from Different Iframes

  getAppletContext().getApplets() method does not return all the J# browser controls when controls are in different iframes. I run the page not from a server but directly from local disk from the same directory. This is an important widely used standard feature and it works fine with java applets. I just tested it with a iis server, and it is a no go. It seems like you have a bug in getAppletContext().getApplets() on a multi frame document. Also, a java console like convenience would have been nice. ...Show All
