• Visual C++ Releasing resources used by Image::FromFile

  Good day, I have an application in which I am dynamically generating images, which I subsequently load into a Picture Box Control, with code something like the following: Image^ image = Image::FromFile( "figure1.png" ); this ->pictureBox1->Image = (Image ^) image->Clone(); delete image; My problem is that the "delete image" does not free up the system resources for the FromFile operation (ie, there is still an O/S file lock on figure1.png). In a nutshell, I'm looking for a methodology which would allow me to write figure1.png any time I want, and view it in the Picture Box Control. I'm aware I could potentially c opy the .png file first, so that the file name I use to write to is neve ...Show All

• Visual Studio Express Editions Intellisense not working

  I have two Windows Forms projects. Intellisense works in one but not the other. I have tried the things in help (deleting the .ncb file, setting options, etc.) to no avail. Not sure what else to try. Any suggestions as to where else to look Thanks. Thomas Yes. What I did was to delete it with C++ Express closed, restarted the IDE and rebuilt the solution. And, I have tried it on two different computers, one running Windows XP Pro and the other XP Home. The Intellisense is really nice to have so I'd like to work my way through to a solution since it may happen with the next app. Thanks. Thomas ...Show All

• Visual Studio Menu items disappear on first use

  Following the model suggested in sample code, I've been able to add to the main menus in the Visual Studio development environment with my Add-In. Curiously, however, my menu items disappear after my first attempt to use any of them. The menus don't, nor do submenus. Only the menu items do. Here's how I am creating them: IdeCommand = IdeCommands.AddNamedCommand2( _ _addInInstance, UniqueName, MenuCaption, Description, True, 0, Nothing, _ CType(vsCommandStatus.vsCommandStatusSupported, Integer) + _ CType(vsCommandStatus.vsCommandStatusEnabled, Integer), _ vsCommandStyle.vsCommandStylePictAndText, _ vsCommandControlType.vsCommandControlTypeButton _ ) IdeCommand.AddControl( _ ParentMenu.CommandBar, _ ParentMenu.CommandBar.C ...Show All

• SQL Server Union for two sets with where clause

  Hi, I have situation where I'm returning comparing data from two date ranges in a chart in MS Reporting Services. In regular SQL, I simply do a UNION between two select statements. I also have a dummy column returned to distinguish between the two selects. i.e. Select *, 1 As 'DataSet' from tblData Where startDate >= @sdate AND endDate <= @edate UNION ALL Select *, 2 As 'DataSet' from tblData Where startDate >= @sdate2 AND endDate <= @edate2 In MDX, I've only seen a UNION for the columns, but not with the WHERE clause included. Is it possible to have a where clause for each set What's the syntax Thanks a lot! WITH MEMBER Measures.Set1 AS 1 MEMBER Measures.Set2 AS 2 SELECT Uni ...Show All

• Visual Studio 2008 (Pre-release) Complex (?) Layout

  Hi all, I'm trying to make a layout which looks like the following image (drew with Expression Design so i have XAML code) : http://img443.imageshack.us/img443/2481/layoutoz8.png The gray area is where the content will be. I want that when i resize my app the "borders" keep the same size and only the gray area gets bigger and thus allow more visible content (ie no Zoom). Is there another way to do this than using a layout "a la Web" : divide my decoration as a grid with 3 columns and 3 rows, the first and last columns and rows gets a fixed size so that only the center gets resized Thanks, Guillaume Hi , Seems this too works. < Grid > < Grid.RowDefinitions > ...Show All
