• Visual C++ Can you share global variables between a DLL and a calling program?

  Can you share global variables between a DLL and a calling program If so I would appreciate any tips. I tried putting the global variables in the DLL but it crashed when the VB porgram tried to call it. DFPercush wrote: Instead of using global variables for file paths etc, use thread local storage. Windows has a set of functions beginning with "Tls*" that manage storage specific to one thread. Your code doesn't look multithreaded to me, so therefore this would be, for all intents and purposes, a global storage space. Use your API text viewer in the start menu > visual basic tools folder, grab the Tls* functions and CopyMemory, and use them to retrieve the value you need in VB.

• Visual C++ 1st TIME USER, please help me to install the STK in Visual Studio 2005

  Hello everyone, sorry if this is a stupid question, but I'm VERY new to this. Have been bumbling through C++ at uni (it's a module on my Sound Tech course) but now it's Xmas holidays and there are no tutors to pester! I've managed to get hold of Visual Studio 2005 and I need to know how to get the STK file working with it. My plan is to build a very simple interface that allows the user to manipulate resonance, filter cutoff, LFO speed etc of a sample they can input. Kind of like a Kaos pad, but without the nice touch screen! Anyway, ANY help would be really appreciated. Thanks, Matt I have no idea what to tell you. Can you be specific about what you don't understand then we might be ab ...Show All

• .NET Development SecurityException, why?

  Hi, I am trying to use IIOPChannel.dll from http://iiop-net.sourceforge.net. It is strongly named assembly. I have another strongly named assembly which calls IIOPChannel.dll. So the order is: program -> mydll.dll -> IIOPChannel.dll. The problem is that I get a Security Exception when mydll.dll tries to link IIOPChannel.dll: SecurityException.Action = LinkDemand. Message: That assembly does not allow partially trusted callers. When I call IIOPChannel.dll directly from my program there is no SecurityException. Unfortunately that is not an option as mydll.dll is required. I have given the assemblies full trust by using caspol: caspol -af mydll.dll. I have also tried setting the AllowPartiallyTrustedCallers attribute on the IIOPchannel. ...Show All
