• .NET Development Any way to marshal / use COM objects created in STA thread from an MTA thread?

  Hey, I have a main thread running in a Single Threaded Apartment (WinForms, but also unit tests run on STAThreads) and I have a couple of managed objects created on that thread that wrap COM objects inside. I would like to use these objects from a background thread that runs as an MTA thread in the ThreadPool (I use a BackgroundWorker in this case). Just passing the reference and calling them from the MTA thread results in lock-up or FatalExecutionException or something very ugly. Although I was expecting the .NET RCW to somehow proxy that call into the STAThread, it doesn't do it and I have found no apparent solution to call my objects f ...Show All

• Visual Studio Express Editions Having trouble watching training videos

  Hi, I'm trying to watch the training videos on Microsoft's site ( http://msdn.microsoft.com/vstudio/express/vwd/learning/default.aspx ), yet the video will pause while the audio continues. Anyway to get these videos to run smoothly without the video pausing for a minute every once in a while I can still here the audio though. Thanks! Leo I downloaded them and I still get the same problem.  For example, on the first video at exactly 15min : 11sec the video pauses and doesn't resume until about 18min : 21sec.  I personally dislike .wmv, I wish microsoft would have giving the option of a ...Show All

• Visual Studio Team System source control- adding empty folder

  Hi Is it possible to add empty folder to source control Thank you all I wasn't able to find out how to do this. However, if you create a dummy file and put it in the directory then you can add the  folder + file in the usual way. I found it useful to create a file called 'index.txt' for each folder and add a few lines to describe its purpose. Will     ...Show All

• Visual Studio Express Editions Creating reports in Vb Express 2005

  Are there any type of reporting features in VB Express 2005   Tried Crystal 9.0 with no luck.  Any help appreciated. John Williams Crystal doesn't come with the Express Editions.  If you're using SQL Server, you can use Microsoft's reporting services.  I think reports can be added from the new item... menu, and report controls are available on the toolbar. If you're not using SQL Server, you'll need to get a third party reporting package.  We use Active Reports, which is pretty good (but not free).  There are some free ones as well, just look around on SourceForge or another open ...Show All

• Software Development for Windows Vista CBaseFilter derived class plays video great, but the audio goes silent after a few seconds...

  Hi all, I have built a filter, derived from CBaseFilter, with two input and two output pins (audio and video IO). The IO pins I derived from CBaseInput and CBaseOutput pins. I have different classes for audio and video pins: i.e. I have 4 types of pin; Audio In, Audio Out, Video In, Video Out. All testing to date has been done in GraphEdit using a webcam & associated mic for input, and default sound & video renderers for output. The Video IO works fine, with the play and stop functionality working too. The Audio IO works for a few seconds before breaking up and going silent. When the Audio pins are connected, the gr ...Show All

• Visual Basic Hiding controls on the designer

  I have a bunch of controls on my form and am wondering if I can hide some so it doesn't look so cluttered. I only wnt to hide them on the designer though and not at runtime. Any way to do this I came up with something similar to Renee's response. I have a collection of group boxes and set their size to 1 pixel by 1 pixel. I set them just outside the edge of the form. When I want to use that groupbox I move it to the right spot then resize it to the right size. At the same time I move the one I am no longer using and set it's size back to 1x1. Of course, this will only work with a fixed form. Oh yeah, and I can hide but I cannot run. ...Show All
