I have to create Editboxes dynamically, which I am creating using loop (loop variable j). 5 components are created successfully, but in 6th component, array shows nil (in debugging process), i.e. nothing was created actually. Again 7th and 8th components are created successfully but 9th doesn't. I have declared variables like-
sud,eud,fud,a,e,c,d,na,st1,st2,citye,statee,pinne,cn,cr,cb,ca: array [0..9] of TEdit;
crr,vcl: array [0..9] of TEdit;
All other components which I declared above are created successfully in that loop.
crr[j+3]:=tEdit.Create(coregroup[i]);
crr[j+3].Parent:=coregroup[i];
crr[j+3].Top:= 77;
crr[j+3].Left:=83+(j*57);
crr[j+3].Width:=17;
I am in the same situation with the code for last two days. If more clarification is required, I may provide you.
The actual code is-
sud,eud,fud,a,e,c,d,na,st1,st2,citye,statee,pinne,cn,cr,cb,ca: array [0..9] of TEdit;
crr,vcl: array [0..9] of TEdit;
dud,leud,lfud,b,f,g,h,nal,st1l,st2l,cityel,stateel,pinnel,dt,cl,crl,cbl,cal,vce: array [0..9] of TLabel;
count,ppointer:integer;
rcaldt: array[0..5] of TDateTimePicker;
coregroup:array of TGroupBox;
