Hi,

In my application, I store an array of TCHAR[MAX_PATH] strings into an vector as indicated by the code snippet below.

//in the .h file
#include <vector>
typedef std::vector<std::basic_string<TCHAR>> StringVector;



//In the .cpp file

BOOL CMyApp::AddStringToVector()
{
	StringVector vect;

	vect.push_back(_T("One"));

	vect.push_back(_T("two"));

	vect.push_back(_T("three"));

	//later on try accessing the vector element.

	TCHAR szResult[MAX_PATH]={0};
	_tcscpy(szResult, vect[1]);
}

I am able to add all the string. But accessing the stored string from the vector is the problem.
_tcscpy(szResult, vect[1]); gives an compilation error
Error 11 error C2664: 'wcscpy' : cannot convert parameter 2 from 'std::basic_string<_Elem,_Traits,_Ax>' to 'const wchar_t *'

I think this error is caused because the TCHAR that is stored in the vector as std::basic_string<_Elem,_Traits,_Ax> and that the compiler is not able to convert it to an TCHAR[MAX_PATH].

How do I go about accessing the TCHAR elements in the vector?

Please help.

Got the solution.

I should be using to access the TCHAR stored in the vector as given below.

_tcscpy(szResult, vect[1].c_str());

Which message gets processed by application when user presses "windows+d" or clicks "show desktop" icon in quick launch so application minimizes?

Well, you get a WM_SIZE[^] message when your window gets minimized but i doubt there is a way to distinguish between the event of "show desktop" and any other cause of minimizing (like the user clicking the minimize button). Why do you have to know that?

I have application, in custome menu I have option "minimize", by clicking on it application goes to sys tray, now menu option would be "restore" ...but that two case(mentioned in Q) option remains "minimize" as application is minimized all ready? it shud be "restore" D'Oh! | :doh:

Well, WM_SIZE[^] with SIZE_MINIMIZED in lParam should tell you your app got minimized and i guess SIZE_RESTORED should tell you if it got restored or SIZE_MAXIMIZED if it got maximized, but if i were you i would rather query the window'S state using GetWindowPlacement[^] and set my menu item accordingly every time the menu is shown, i think it is easier to handle than tracking some flag thoroughout the application...

Application does not get WM_SIZE message in both case mentioned in Q.

Hmm, you are right, one would think it would get a WM_SIZE, same with WM_WINDOWPOSCHANGED...sorry about that...i see what else i find, if i figure out anything i will get back to you...how about GetWindowPlacement mentioned in my other[^] post?

Still I'm confused, application minimizes (in both cases) but message Q does not process any message how this is possible?

Owner window doesn't show [modified]

8-Mar-09 22:35

I have found several answers to what happens with a window when the desktop is shown, so now i am also confused:
-the window gets minimized
-the window gets hidden
-the window gets moved to a poisition way outside of the visible area
-the desktop window simply overlaps the window (so the window gets send behind the desktop)

So finding out if your window is hidden or not by "show desktop" seems trickier than we thought...

I show a message box with AfxMessageBox.

However if my main dialog was minimized at that time, only the message box shows, and until OK is clicked the owner won't show even if I click on the program icon in the task bar.

Same if I use a custom dlg with DoModal instead of a message box.

This happens only if the main dlg was minimized, if it was simply out of focus there's no problem.

There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.
