Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. See this article on possibly handling these exceptions.ĭoes the sample code here work? You need to make sure the unmanaged code doesn't write past the end of the StringBuilder's buffer. The winuser.h header defines GetWindowText as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. This is happening because you are calling an unmanaged method which is writing past the end of a buffer. Version 2.32 has fixed crash of GetWindowText under Windows 8.1. The above message is from an AccessViolationException, which is a kind of corrupted state exception. Net 4, managed code does not handle these exceptions by default. These kinds of exceptions can be very bad because the CLR cannot be sure that its own internal state is consistent and are sometimes called corrupted state exceptions. nMaxCount to 1 but most of the times I get nothing in my lpString, and.
to get the text with GetWindowText () and GetDlgItemText (). This mechanism is called structured exception handling. Thank you very much Solution 2 You can use GetFocus () to get Handle of active window (the window is working by user), after that you use GetWindowText () to get caption of that window (the first parameter is the return value of GetFocus ()), you can check them (two functions above) on MSDN page. I have several static controls with EMLIMITTEXT set to 1.
Another type is one delivered to the CLR via the windows OS. One type is StackOverflow or OutOfMemory because there is literally no memory to allocate for the handler to run. I have created an application which create many CWnd.There are some exceptions that cannot be caught. The function getWindowText of my module is called by My first Thread ,this function save param of a control and param specific of a function which will call, then i save in a list of structure, Finally I Set a' function Event ' and i wait on the first or second thread but i have the same result, a dead lock when i called GetwindowText of.
