I have a problem with adding ltmm20.dll to the new Visual Studio project.

The idea is to use ltmmConvertCtrlClass as an alternative to Windows Forms dependent ConvertCtrl for video concatenation.
I've somehow managed to add ltmm20.dll (Win32 version) to one of your C# examples (ConcatSameSizeDemo), but I am unable to do so in newly created project for which I've set same properties, platform and framework version.

Adding dll as a reference should result in creating an application extension in obj/Debug folder called LTMMLib, but instead I get ''The referenced component "LTMMLib" could not be found'' warning, and a pretty much broken reference.
A "workaround" would be to actually add generated Interop.LTMMLib from obj/Debug as a reference, instead of ltmm20.dll. Don't know about stdole.dll, but the project builds.

Any suggestions?

Hello,

Unfortunately since I was testing with a console application I had to use the System.Windows.Forms.Application.DoEvents call in order to properly handle the message queue, but this reference is not technically required for the application to work. If you'd like to test this, simply remove the System.Windows.Forms reference, and replace the do/while loop with something like System.Threading.Thread.Sleep(10000). Ten seconds should be more than enough time for the sample file to convert.

If you are still having issues after using the sample application below, please let me know.
