In order to avoid infinite loop, I think you can first try this:
static bool isMyMessageBox = false;
if( ! isMyMessageBox)
{
isMyMessageBox = true;
::MessageBox(....);
isMyMessageBox = false;
}
If it works, you should take care it works in multi-threaded case too. (Probably TlsGetValue and TlsSetValue can help).

Well I guess you need to use the WH_CBT hook and check the LPARAM for the HCBT_CREATEWND.

i ahve one dialog box ont that i have a bitmap i.e world map once i point out any point in that bitmap at that point i have to open a child dialog box on that we should get the relative time.
my problem is when i point out particular area i get hte child window. but i dinot get the time because this child window is taking the points from windows so that we are unble to campare with the parent dialog window.
please tell me how we get parent points in child or else how we can send pointsd from main to child window
|

I assume the logic to determine the time is in your child dialog. If that is the case,
1) If you used GetCursorPos(...) to get your point, then you have to call ScreenToClient(...) to convert them to client coordinates.
2) Then before you display your child dialog with DoModal(), store these coordinates in your child dialog.

if the point in the main dialog is (428,500) by using this
ScreenToClient iget x=-5;
so please help me,
sree.

Post some code on how you get your point, as well as the part where u call ScreenToClient(...)
|
|
|
|
|
i used this in on timer in child window
GetCursorPos(&cp1);
ScreenToClient(&cp1);
i think screentoclient taking client as child window.
sree.

ScreenToClient(...) takes 2 parameters, first one is a handle to your window, the second is your point. Since you are calling this in your child window, then you have to call GetParent() to get the handle to your parent window and pass it into ScreenToClient(...). e.g.
GetCursorPos(&cp1);
HWND hParentWnd = GetParent();
ScreenToClient(hParentWnd, &cp1);

I Think following change sholud be there in program.
<br />
::ScreenToClient(hParentWnd, &cp1);
Check the Scope Resolution Operator( :: ) before ScreentoClient API.
I Think this correction should be there.

Yes, it is applicable as well.

i got an error getparent does not take one parameter

Try putting the scope operator asMahesh have pointed out:
GetCursorPos(&cp1);
HWND hParentWnd = ::GetParent();
::ScreenToClient(hParentWnd, &cp1);
|

again iam getting window coordiantes.not parent co-ordinates
please help me.
CProfileWindow myWindow;
HWND hParentWnd = ::GetParent(myWindow);
::ScreenToClient(hParentWnd, &cp1);
|

Didn't you said you are calling it from OnTimer of your child window? If that's the case, then you should get the handle of that window for GetParent(...).
Btw, are you using mfc?
|
|
|
|
|
"that window",which window should be handled,yes,iam calling from OnTimer(),can u explain in detail please,
sree.

If you are using mfc, then you can do this:
AfxGetMainWnd()->ScreenToClient(&cp1);
