Hi all! (once again) I try to build dll library bases on pjsip similar to pjsipdll from sipeksdk (http://sites.google.com/site/sipekphone/pjsipwrapper), and my dll works very well if i bulid it without video... if I join video my dll's broken. Any function from dll like that: *int test()* *{* *return 0;* *}* don't work, I get only error: *System.DllNotFoundException was unhandled Message = "Unable to load DLL pjspDLL.dll': Could not find specified module. (Exception from HRESULT: 0x8007007E)" Source = "Test - only pjspdll" TypeName = "" StackTrace: in Test.Form1.test (Int32 a) in Test.Form1 .. ctor () in E: \ VB \ Test - only pjspdll\ test - only pjspdll\ Form1.cs: line 22 in Test.Program.Main () in E: \ VB \ Test - only pjspdll\ test - only pjspdll\ Program.cs: line 18 in System.AppDomain._nExecuteAssembly (Assembly assembly, String [] args) in System.AppDomain.ExecuteAssembly (String assemblyFile, assemblySecurity Evidence, String [] args) in Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly () in System.Threading.ThreadHelper.ThreadStart_Context (Object state) in System.Threading.ExecutionContext.Run (ExecutionContext executionContext, ContextCallback callback, Object state) in System.Threading.ThreadHelper.ThreadStart () InnerException:* I try to copy in project directory the same dll file's (avcodec-52.dll etc.), that i used to turn on pjsua, but it don't brings any results. I used too http://www.dependencywalker.com/ to look missing dependency but it show nothing special. Greetings Andrew -------------- next part -------------- An HTML attachment was scrubbed...
