I'm using the MSDN documentation. // Step 0) Acquire context if (!CAPI.CryptAcquireContext(ref this._cryptographicProvider, null, null, CAPI.PROV_DSS_DH, CAPI.CRYPT_VERIFYCONTEXT)) HandleWin32Error("Unable to acquire cryptographi...
I have tried to change the timezone of my system with c# code for a few days now and nothing I'm trying is making much sense or working at all. I started out trying to use the PInvoke syntax for SetTimeZoneInformation that I've seen on other questions here. [DllImport("kernel32.dll", CharSet = CharSet.Auto)] private static extern bool ...
I'm building a small GUI-Test automation tool in C# for a application. One of the functions in the test tool is to close dialogs pops up from the tested application. The trouble that I have is to find the button to click on without giving the full class name. I have used the FindWindowEx method to get the dialog box and the button that ...
Hi, I have implemented a p/invoke command in my compact framework based application which invokes the windows calibrate screen.

Consider the following struct to be sent over TCP to an unmanaged dll [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)] public struct FooMessage { [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 42)] public string foo; //More fields... } Using the following function (credit to Cheeso): public byte[]...
I have a C++ DLL that I have source to. It is currently logging to stdout. I am calling methods in this dll via pinvoke from c#. I want the c# code to be able to get the log messages, and then forward them to the c# application's own logging mechanism. I have seen some questions/answers dealing with capturing stdout, but I cannot get ...

I'm developing an application that will allow users to call external code from both managed and native .dlls. The users will be able to specify what library/method/function to call at runtime (it will be stored in a configuration file). I know how to do this using pinvoke for native libraries if I know what dll/function I want to call ...
When working with the access rules returned by GetAccessRules(True, True, GetType(System.Security.Principal.NTAccount)) how can I tell if the NTAccount object referenced in each rule is a user account or a group? Update: I was able to solve this as follows. Note, the intent of this code is to return True if the NTAccount is a grou...
Ok, I have the HDF5 library downloaded from the official site, and I have a few DLLs, including hdf5dll.dll, and hdf5_hldll.dll. I have what I think to be some wrappers around the native calls, in my classes H5, H5LT, H5F, and H5T. Example from H5.cs: namespace HDF5 { using hid_t = System.Int32; using herr_t = System.Int32; ...
I am almost buried by how the different dialects of types are matched between .NET world and native world. Such as MFC CList and other stuffs. I am desperately hoping for this: Some kind of table or cheetsheet that lists all the mappings between types of .NET world and native world. A table that lists all the types that can be marshal...
I have a situation where I must use Windows API to retrieve text from a Rich Text Box in another program; I am wondering if there is any way to get the ...'rich text' from it, and not just the plain text. In this example, ptrHandle is the RichText Control Handle. if (ptrHandle == null) return null; if (ptrHandle == IntPtr.Zero) ...
I'm trying to detect the show system and hidden files settings from Windows Explorer in an application I'm writing. I'm using SHGetSetSettings and in calling it I have to specify one or more of the SSF Constants to specify what settings to retrieve. Finding out the hidden files settings was easy enough, I just had to specify SSF_SHOWAL...
I just switched to vs2010 from vs2008. Exact same solution, except now every single call to a C++ dll yields a 'pinvokestackimbalance' exception. This exception does not get fired in 2008. I have complete access to the C++ dll and to the calling application. There does not appear to be any problem with the pinvoke, but this problem i...
How is it possible to marshal a shared_ptr from unmanaged C++ code into C#? I have a function in C++ (exposed through C bindings) that will allocate a new MyObject and return a pointer to it via a shared_ptr. In C++ I can call the function: MyObjHandle* ref = NULL: GetMyObject(&ref); // double ptr... where MyObjHandle is defined: ...

I have a method set that uses pinvoke to call WM_GETTEXT on another program's textbox - and it works fairly well, but frequently I just get back total junk text appended to the end of it. (The ORIGINAL text is always intact.) This is random, I cannot reproduce it on demand, but it is frequent enough to be stopship. Here is the text to ...
Part of an idea of mine are the following things: Mouse access in a C# console application Setting a special font for a console application (to provide the correct codepage 437 with all the RIGHT graphical stuff, not that é and à - stuff) Providing a DirectX - graphical - window on top of a console application that moves with the conso...
