On seeing h_init.prg line no. 131 there is a system variable for all the form types defined by a HMG application.
Code: Select all
_HMG_SYSDATA [ 69 ] -> _HMG_aFormType
The length of this _HMG_SYSDATA[69] will be equal to the total number of forms defined at any time.
So, you can use len(_HMG_SYSDATA[69]) to find out the number of forms.
Split child windows are also taken into account as forms. This array can have values "A","C","S","M","X"
"A" means Main Window
"C" means Child Window
"X" means Splitchild Window
"M" means Modal window
"S" means Standard window
If you want the number of main, modal and child windows use this loop.
Code: Select all
nCount := 0
for i := 1 to len(_HMG_SYSDATA[69])
if (_HMG_SYSDATA[69,i] == "A" .or. _HMG_SYSDATA[69,i] == "M" .or. _HMG_SYSDATA[69,i] == "C")
nCount++
endif
next i
msginfo("There are "+str(nCount)+" windows defined")

Thanks a lot Rathi,
Great!!!
I want it to ensure that when user will try to change Accounting Year online, no other window (except main window) will be opened
Your code will be extremely helpful to me
With best regards.
