I’m not sure if there’s a niifty .NET wrapper, but you could call the FormatMessage API using P/Invoke. See this answer for how it would normally be called from native code. Though the question refers to grabbing error codes from HRESULTs, the answer also applies for retreiving codes from the regular OS error codes coming … 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
Google quickly found http://www.pinvoker.com (Wayback) (Compatiblity listed as VS2005, 2008, and 2010; it doesn’t seem to have been updated to work with newer versions) Microsoft’s C++/CLI compiler can also do this, if you use /clr:safe and #include the header file, it will generate p/invoke code which you can extract with e.g. ILSpy (free) or Red … Read more
Get the window handle (hwnd), and then use this user32.dll function: VB.net declaration: Declare Function SetForegroundWindow Lib “user32.dll” (ByVal hwnd As Integer) As Integer C# declaration: [DllImport(“user32.dll”)] public static extern int SetForegroundWindow(int hwnd) One consideration is that this will not work if the window is minimized, so I’ve written the following method which also handles … Read more
The reason you cannot pass null is because a ref parameter is given special treatment by the C# compiler. Any ref parameter must be a reference that can be passed to the function you are calling. Since you want to pass null the compiler is refusing to allow this since you are not providing a … Read more
I had a _cdecl c++ dll that I called without any trouble from Visual Studio 2008, and then the identical code in Visual Studio 2010 would not work. I got the same PInvoke … has unbalanced the stack error as well. The solution for me was to specify the calling convention in the DllImport(…) attribute: … Read more
You can enable/disable devices from Win32 (and hence from C# via P/Invoke) using the SetupDi APIs but not all devices are “disable-able” in this way. The problem you’ll run into trying to disable your touchpad from Win32 (or WMI or any other API which calls down into the SetupDi* family of functions) is that the … Read more
You must return this as an IntPtr. Returning a System.String type from a PInvoke function requires great care. The CLR must transfer the memory from the native representation into the managed one. This is an easy and predictable operation. The problem though comes with what to do with the native memory that was returned from … Read more
It is 2018. The project fortunes have changed quite a bit. CefSharp is alive and well with almost daily updates in the GitHub depository. Issues are getting resolved, currently only 57 open issues and 1787 closed. CefGlue does not seem to do well. The mailing lists are moribund, there have not been recent updates. There … Read more
The profiler APIs are returning metadata specified in the managed code, normally via the DllImportAttribute. In the case of the ‘dynamic pinvoke’ which uses the Marshal.GetDelegateForFunctionPointer method, the module and function names were never specified as metadata and not available. An alternative approach to dynamic pinvoke declarations that includes the required metadata will probably avoid … Read more
