GetWindowText
The GetWindowText function copies the text of the specified window's title bar (if it has one)
into a buffer. If the specified window is a control, the text of the control is
copied.
int GetWindowText(
HWND hWnd,
| // handle of window or control with text
| LPTSTR lpString,
| // address of buffer for text
| int nMaxCount
| // maximum number of characters to copy
| );
|
|
Parameters
hWnd
Identifies the window or control containing the text.
lpString
Points to the buffer that will receive the text.
nMaxCount
Specifies the maximum number of characters to copy to the buffer. If the text
exceeds this limit, it is truncated.
Return Values
If the function succeeds, the return value is the length, in characters, of
the copied string, not including the terminating null character. If the window
has no title bar or text, if the title bar is empty, or if the window or control
handle is invalid, the return value is zero. To get extended error information,
call GetLastError.
This function cannot retrieve the text of an edit control in another
application.
Remarks
This function causes a WM_GETTEXT message to be sent to the specified window or control.
This function cannot retrieve the text of an edit control in another
application.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
