I am trying to programmatically input some command to Matlab Command Window, which consists of such window hierarchies (using spy++), as shown below: There are however few article or tutorials, and this post presents my first trial in using this. ManagedWinApi is such a kind of tool to make life easier.
I have done quite a few coding using this, and it worked, but the pitfall is that you have to dive deep into the low level APIs, which may distract you from the current focus. All rights reserved.The C# interop/PInvoke is a good tool: it allows you to call C API directly, and do something which might be hard to get using managed API.

GetWindowTextLength | SetWindowText | WM_GETTEXT | Windows Functions If the window does not have a caption, the return value is a null string.
If the target window is owned by another process and has a caption, GetWindowText retrieves the window caption text. If the target window is owned by the current process, GetWindowText causes a WM_GETTEXT message to be sent to the specified window or control. When working with RAPI for Windows CE 1.0 and 1.01, use the PegGetWindowText function. This function cannot retrieve the text of an edit control in another application. To get extended error information, call GetLastError. Zero indicates that the window has no title bar or text, if the title bar is empty, or if the window or control handle is invalid. The length, in characters, of the copied string, not including the terminating null character, indicates success. If the text exceeds this limit, it is truncated. Specifies the maximum number of characters to copy to the buffer, including the NULL character. Long pointer to the buffer that will receive the text. Handle to the window or control containing the text. intGetWindowText( HWNDhWnd, LPTSTRlpString, intnMaxCount )
A remote application interface (RAPI) version of this function exists, and it is called CeGetWindowText (RAPI). If the specified window is a control, the text of the control is copied. This function copies the text of the specified window's title bar - if it has one - into a buffer.
