From: Joel Whitehouse on 22 Feb 2005 13:02 Hi Guys, I have a project that declares several functions from multiple .dlls, including a few user32 APIs, and functions from a 3rd party .dll. My trouble comes when I try to declare functions from a .dll file that I wrote in VC7. Whenever I run a line of code that calls my library "MastController.dll", I get the following: "Run-time Error 53: File not found: C:\Program Files\Microsoft Visual Studio\MyProjects\MastCont\MastControllerTest\Debug\MastController" My declare statement looks like this: Public Declare Function MastMove Lib "C:\Program Files\Microsoft Visual Studio\MyProjects\MastCont\MastControllerTest\Debug\MastController.dll" Alias "Move" (ByVal hWnd As Long, ByVal Msg As Long, ByVal nAzimuth As Long, ByVal nElevation As Long) As Integer Like I say, *other* .dlls that I'm using are working porperly, and I was even able to get a VC7 driver to test the functions of MastController.dll. I also tried placing MastController.dll in app.path and the system32 directories, as well as the vb6.exe directory and using a declare statement without a path, but I get eth same result. What am I doing wrong? -Joel Whitehouse

It's all on one line. Should I break the line up? -Joel

DLL is a regular DLL with the function exported? Function name is spelled correctly? One thing to try (when all else fails) is to punt (reboot). <g> Clean the project up - Remove any possible reference to the dll in your project. Remove all other possible "Declare" directives to that library. Place the DLL in your app directory or anywhere there is a simple 'path' to it (just to keep it simple while testing). Close and save the project. Delete all temp files, and reboot. you never know... and besides it will give you the feeling you are doing something useful. <g> -ralph
