Hi Russell,
FindWindowEx always gives NULL. When I click on New, a new child window opens with titile "MyView1", "MyView2",... When I click this menu item, I want the child windows to be repainted one at a time. Pls have a look at the code:
void CMainFrame::OnUpdateViews()
{
CString strTitle ;
static int nChild = 1 ;
strTitle.Format("MyView%d", nChild) ;
HWND hWnd = ::FindWindowEx(
this->GetSafeHwnd(),
NULL,
"CMyView",
(LPSTR)(LPCTSTR) strTitle) ;
if(::IsWindow(hWnd))
::SendMessage(hWnd, WM_COMMAND, (WPARAM)WM_USER, 0) ;
nChild ++ ;
}
In my WM_USER handler, I simply call "Invalidate()". Instead of repainting all the children, I need to do it for a specific child window.
Hope I have explained my problem clearly.

Well, ...how to use this routine more times? the variable 'nChild' looks hard to be reset, or not?
About your function: everything looks correct, but:
The CView is child of a frame that is child of the MainFrame, I don't know if it is a problem for FindWindowEx.
Are you sure that strTitle contains the right title? In debug mode you can check the RuntimeClass.

Hi Russell,
Pls forget abt 'nChild'. As you said, I tried this:
HWND hWnd = ::FindWindowEx(MDIGetActive()->GetSafeHwnd(),
NULL,
"CMyView",
(LPSTR)(LPCTSTR) strTitle) ;
But in vain. What else can solve this problem?

I think that this must work: :->
POSITION ViewPos;
CView* pView;
CString string;
ViewPos=pDoc->GetFirstViewPosition();
while(ViewPos){
pView=(CSWAView*) pDoc->GetNextView(ViewPos);
pView->GetWindowText(string);
if(string==strTitle){
...
}
}
In this way you could refresh more View (if exists) with the same name.

No it will not. It will remove the object from the list, but will not free the memory it pointed to. That is your responsibility. You can check this in the CList source code if you want.

How could i block certain area with a rectangle out of 400*400 pixels in a bitmap
|
|
|
|

Do you need to segment from one bitmap? if yes I suggest use BitBlt
|

can we use static allocation instead of dynamic one with structures to vector array
typedef _strct{
int field1;
int field2;
...
}STRCT;
////////////////////////////////////////////////
func(){
vector<STRCT> vec;
...
fillvector(&vec, N);
...
}
/////////////////////////////////////////////////
fillvector(vector<STRCT> *vec, N)
{
for(int i=0; i<N; i++)
{
STRUCT str;
str.field1 = rand();
str.field2 = rand();
...
vec->push_back(str);
}
}
or is it better to get a STRUCT *str = new STRUCT to a vector<STRUCT *> vec

How will you reallocate a static struct?

Yes, it's perfectly safe to use it that way. The vector will make a copy of your struct and hold the copy.

You have to enable the Edit and Continue option.

Thanks , but where this option is define in the Visual ?
|
|
|
|
|
In the Project Settings dialog box that appears, click the C/C++ tab. Select General from the Category group box. In the Debug info group box, select "Program Database for Edit and Continue." The /ZI compiler switch will appear in the Project Options box at the bottom of the dialog box. Any other selection in the Debug info group box will disable the /ZI compiler switch. Click OK to accept the settings.
More[^] info.
