Compiler: Visual Studio Standard Edition 4.0
My program uses 10 edit controls three of which are read only and 2 push buttons. I am using the tab-stop style
controls. My problem is that when navigating the controls
with the mouse the program hangs after clicking each input
control about six times. If I navigate the controls with the tab key I don't have this problem at all. This program
performs calculations for building an antenna for amateur
radio use and includes a graphic of the antenna.
If I process WM_LBUTTONDOWN in the main window 40-50 times the program hangs. So it happens even if I'm not using the edit boxes. Sorry if I'm not making everything clear. The user
enters values and then presses the calc button for one calc and does the same for another
calculation. Two sets of edit controls and two push buttons.
My problem is that when navigating the controls with the mouse the program
hangs after clicking each input control about six times
Are you clicking it 6 times in succession, or clicking it once to gain focus then clicking some other control then some other control etc round-robin style until one of them has been clicked 6 times?

Does that have anything at all to do with the problem? If these calculations and image drawings are not taking place until a "go" button is clicked, then you can omit this part from consideration. Otherwise, if you are performing calculations and drawing images in response to controls receiving/losing focus or changing content, therein may be where you need to look.

The graphic is simply used as a diagram of the antenna that pictures the dimensions needed
for the equations. I do mean that values are plugged into each field six times or so before
the program hangs using the mouse to select each field. So, if the user does a lot of playing
around with different dimensions and frequencies during the same session and uses the mouse to change from one field to another the program might hang.
Is there a manual or web site or book or ... that has describe office automation classes for C++?
I mean classes like(for Excel) :
because the method parameters names is not named good, and in MSDN there is no complete reference like MFC classes.
I use word and excel automation in our MFC app
Hi, I thing when you say poniter its pointer.
All strings and arrays in C are pointers so you cant change it.
However if you want to create a string otherwise you can use malloc, with malloc you can create one array of any size, you can see it here
But you have other way to do it, if you want to read a string for keyboard you may be need to use strdup() from string.h
