Here is a pretty standard scheme for asynchronous background processing with VB6 clients and VB6 servers. (For instance it’s in Dan Appleman’s book and Microsoft’s VB6 samples.) I think it should work for a C# client too. The VB6 ActiveX EXE object should expose an event CheckQuitDoStuff(). This takes a ByRef Boolean called Quit. The … Read more
In the Jedi Code Library (JCL) – free – there is a JclDotNet.pas, containing a class TJclClrHost, probably doing what you want: TJclClrHost = class(TJclClrBase, ICorRuntimeHost) private FDefaultInterface: ICorRuntimeHost; FAppDomains: TObjectList; procedure EnumAppDomains; function GetAppDomain(const Idx: Integer): TJclClrAppDomain; function GetAppDomainCount: Integer; function GetDefaultAppDomain: IJclClrAppDomain; function GetCurrentAppDomain: IJclClrAppDomain; protected function AddAppDomain(const AppDomain: TJclClrAppDomain): Integer; function RemoveAppDomain(const … Read more
Beginning with the R2009a release of MATLAB, .NET objects can be accessed from MATLAB: http://www.mathworks.com/help/techdoc/matlab_external/brpb5k6.html In older versions of MATLAB, it is possible to access .NET objects from MATLAB using CCW: http://www.mathworks.com/support/solutions/data/1-5U8HND.html?solution=1-5U8HND and the MATLAB engine from .NET: http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/matlab_external/f135590.html#f135616 You can also use the MATLAB Builder NE to wrap m-code into .NET assemblies. http://www.mathworks.com/products/netbuilder/
You embed jython and you will use some Python-Modules somewere: if you want to set the path (sys.path) in your Java-Code : public void init() { interp = new PythonInterpreter(null, new PySystemState()); PySystemState sys = Py.getSystemState(); sys.path.append(new PyString(rootPath)); sys.path.append(new PyString(modulesDir)); } Py is in org.python.core. rootPath and modulesDir is where YOU want ! let rootPath … Read more
I ran into this same error being thrown when I deployed my application onto a machine without a fully activated and licensed installation of Excel. I spent hours trying to diagnose the issue. Make sure you check your Office installations to make sure they are complete.
I realize that this may not be an exact answer to your question, but I figured I would put my 2 cents worth in as I doubt to many people have tried this. I got it to work by created a managed wrapper using mixed mode C++. There are other ways to do it, but … Read more
In .net 4 static Add() and Subtract() methods have been added. IntPtr ptr = IntPtr.Add(oldPtr, 2); http://msdn.microsoft.com/en-us/library/system.intptr.add.aspx
The issue is described here: Is it safe to call an RCW from a finalizer? and here: Release Excel Object In My Destructor The trouble is that not only is the timing as to when these objects are to be garbage collected uncertain, but the order in which the finalizers are called is also nondeterministic. … Read more
These are the VK_MEDIA_NEXT_TRACK and VK_MEDIA_PREV_TRACK virtual keys. The processing for them is highly convoluted: Whatever program owns the foreground window will retrieve his keystroke from its message queue when it calls GetMessage() The TranslateMessage() call in that program’s message loop translates the keystroke to a WM_APPCOMMAND message, APPCOMMAND_MEDIA_NEXTTRACK or APPCOMMAND_MEDIA_PREVIOUSTRACK and sends it to … Read more
You discovered that WPF calls SetProcessDPIAware(). It happens inside the module initializer for PresentationCore. Which is formally illegal, it must always be called before an app creates any windows or load DLLs that might cache the DPI value. Or in other words, lots of ways that this can go wrong, you only discovered the mild … Read more
