instance of an application is running or not????

[sunil.thaha]

Could u please explain what do intend to Do ?

Since accessing a pointer to a Form Created within Another is very Rare

Any way

int main() {
   D1 d1;
   d1.d2->updateContents()
}

int main() {
   D1 d1;
   d1.d2->updateContents()
}

To copy to clipboard, switch view to plain text mode 

Please recheck the Design before u decide to do this !!
