• Visual C# Not Freeing Memory

  Hi, I don't know if anyone can help me. I am working with large png files, and finding the memory is not being freed after the object is disposed. Are there any know bugs on this issue Many thanks, Bruce Hi James, Thanks. I have had a look and can't seem to find GC.Collect() within the code. Running through the memory profiler, the garbage collector is collecting instantly after it previously freed some memory. To try and picture this, it starts off at the bottom left corner and increases rapidly diagonally up the screen freeing memory and then the app throws an out of memory exception, before the plugin dies.

• Software Development for Windows Vista Running SQLPersistanceService examples on WWF Beta 2

  Fellas, I have installed WWF B2 and its required extensions++. I could run some of the samples fine. There are a couple of demos that didnt work well and I think it was related to the use of SQLPersistanceService. I tried to look for the scripts at %SystemRoot%\Microsoft.NET\Framework\v2.0.50215\Windows Workflow Foundation\SQL but it is not there. The installed framework on my machine happened to be of v2.0.50727. So there I cannot create the schemas for the SQLPersistanceService. How do I get this to run with WWF B2 as well as the JanCTP Frameworks. Any hackarounds or advice is appreciated. Thank you You will find the scri ...Show All
