form( const form &forminstance)
{
setParent(GetParent(forminstance.hwnd));
height=forminstance.height;
left=forminstance.left;
top=forminstance.top;
width=forminstance.width;
/*setTextAlignment(forminstance.intTextAlignment);
intMouseHover=forminstance.intMouseHover;
setAutoSize(forminstance.blnAutoSize);
setEnable(forminstance.blnEnable);
setTabStop(forminstance.blnTabStop);
setTextWrap(forminstance.blnTextWrap);
setTransparent(forminstance.blnTransparent);
setVisible(forminstance.blnVisible);
setBackColor(forminstance.clrBackColor);
setTextColor(forminstance.clrTextColor);
strCaption=forminstance.strCaption;
hCursor=forminstance.hCursor;
SetClassLong(hwnd, // window handle
GCL_HCURSOR, // change cursor
(LONG) hCursor);
HFONT a=(HFONT)SendMessage(forminstance.hwnd, WM_GETFONT, 0, 0);
setFont(a);*/
}

and these:
1
2
3
4
5
6
7
8
9
10
11
12
|
form(string caption = "", HWND parent=HWND_DESKTOP)
{
if(hwnd==NULL)
{
++FormCount;
if(caption=="")
strCaption = strCaption + to_string(FormCount);
else
strCaption=caption;
setParent(parent);
}
}
|
heres using the vectors:
1
2
3
|
vector<form> frmmdi;
frmmdi.push_back("hello world");
frmmdi.parent=fb;
|
the form are showed and then deleted.
but the:
vector<form> frmmdi(2);
so when i use the push_back(), can i use the form constructor?

vector<std::unique_ptr<form>> frmmdi;
void CreateDMI(vector<std::unique_ptr<form>> &frmmdiwindow, HWND parent)
{
frmmdiwindow.emplace_back(new form("hello world"));
frmmdiwindow[frmmdiwindow.size()-1]->Parent=parent;

{
HWND hwndMDI=GetForegroundWindow();
for(int i=0; i<=frmmdiwindow.size()-1; i++)

if (hwndMDITemp==hwndMDI)
{
frmmdiwindow.erase(frmmdiwindow.begin()+i);
break;
}
}
};
}
//....
btnarray[0].MouseClick=[]()
{
fb.setAutoScroll(true);
CreateDMI(frmmdi,fb);
};

now see when a form is closed:
1
2

case WM_CLOSE:
{
inst->Close();
FormCount-=FormCount;
DebugText((string)"form count: " + to_string(FormCount));
DestroyWindow(inst->hwnd);
}
break;
case WM_DESTROY:
{
inst->Destroy();
joyReleaseCapture(JOYSTICKID1);
KillTimer(inst->hwnd, JoystickTimer);
KillTimer(inst->hwnd,KeyBoardTimer);
KillTimer(inst->hwnd,timerid);
if(FormCount<0)
End();
}
break;

when i create a form:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
form(const string caption = "", const HWND parent=HWND_DESKTOP)
{
if(hwnd==NULL)
{
++FormCount;
DebugText((string)"form count: " + to_string(FormCount));
if(caption=="")
strCaption = strCaption + to_string(FormCount);
else
strCaption=caption;
setParent(parent);
}
}

i'm debugging the FormCount. when the form it's created seems ok. but when it's destroyed, the results aren't correct :(
can you advice me?
resolved with these code:
1
2

~form()
{
if(hwnd!=NULL)
{
FormCount=FormCount-1;
DestroyWindow(hwnd);
}
}
////.............
case WM_CLOSE:
{
inst->Close();
if(IsWindowVisible(inst->hwnd)==TRUE)
FormCount=FormCount-1;
if(FormCount>=1)
{
ChildWindows ws(inst->hwnd);
for(int i=0; i<ws.count(); i++)
{
SendMessage(ws[i], WM_CLOSE,0,0);
}
}
DestroyWindow(inst->hwnd);
}
break;
case WM_DESTROY:
{
inst->Destroy();
joyReleaseCapture(JOYSTICKID1);
KillTimer(inst->hwnd, JoystickTimer);
KillTimer(inst->hwnd,KeyBoardTimer);
KillTimer(inst->hwnd,timerid);
if(FormCount<1)
End();
inst->hwnd=NULL;
}
break;

give me 1 advice: is good, after close all forms, end the program automatic or is better using the command for end it?
