• Windows Forms ToolStripMenuItem (image and text) disabled causing "Out of memory"

  I have a context menu with menu items having images displayed next to the menu text. When I disabled one menuitem in runtime, the app. crashed with Out of memory exception. I could work around the exception by setting the toolstripmenuitem's image property to null before disabling it. However, I think this shouldn't be this way, could this be a bug or I did something wrong. Please help. Thanks. I created a small test project with a menu/contextmenu and items with pictures loaded directly and from an imagelist. I then disable/enable items bu I can not reproduce what you describe.

• SQL Server Data Flow limitation?

  I have a unique situation where I need to process 40 mb (100,000 rows) worth of data from a flat file and order the data by a key and place it in SQL server table. My problem is that SSIS data flow processes data in batches defined by BufferSize and BufferMaxRows and I cannot seem to process 40 mb worth of data ALL AT Once. Ie. My flat file has data that is in fixed width. First column includes id such as AA, BB, CC. These rows are not orded in the flat file. So I use Conditional Split to order the rows, however, since SSIS buffer is not large enough to process all the rows at once, it takes first 10,000 rows orders them, then next ...Show All

• Software Development for Windows Vista VMR9 and HD Resolution Video

  I've been having some problems with displaying DivX HD Video in my application that uses DirectX9 together with VMR9. I have been talking about problems with VMR9 before and that the only solution so far have been putting a Sleep(10) in the render loop to get rid of (I guess) blocking problems. The blocking has for me caused problems with the video not playing in full frame rate. Now, the problem is that to get DivX HD (for example) content to play smoothly I have to Sleep(25) or more, and this is a problem because I'm trying to run DirectX at 60hz or more and then everything else will not be able to play smoothly. Windows Media HD works nic ...Show All

• Software Development for Windows Vista How to go 'backwards' in a sequential workflow?

  Hello I am planning on using a sequential workflow to drive a wizard-style form interface with [next] and [previous] buttons. Most (all ) examples of sequential workflows I've seen show the flow proceeding from the start to the finish. My requirements are that the user is able to click the [previous] button at any time and be moved to the previous activity in his/her workflow. E.g. Say I have a flow like this: A / \ B C | D / \ E F And that the user moves from A-B-D-F (according to rules/decisions). If the user hits [previous] when activity 'F' is active, I want to be able to move the workflo ...Show All

• Visual Basic VB.NET 2003 Multiple Application Interface - Best Method?

  Hello, I am creating an application in VB.NET 2.0 that I envision having an outlook style bar down the left hand side that shows icons, and a brief text description; then when the image is clicked, the appropriate application will launch (think of Multiple document interface kind of feel to the applications) to the right of the outlook style bar in a child window. What I am curious about, is what would be the best method for creating the main, and separate clickable apps to maximize the ability to have different people working on various separate applications at the same time and then allow us to easily "plug" these into the main applicati ...Show All
