I've global module whuch has sub main() from where the application starts and also a callback function. I load my MDI by deciding in the callback which MDI is to be loaded. C dll tells UI about this in the callback. Now once an MDI is loaded, say the callback in global module recvs another instruction to load another MDI/form. Here if i use new form.show(), the control goes into the new form's load event and does all, but the form comes up and disappears. If i use showdialog(), then the form is seen but the control doesn't come back unless the newly opened form is closed. this is what i dont want. i want to return as well from the callback after opening the new form. .show() allows me that, but the form doesn't stay, and showdialog() doesn't allow be to retrn. and in the .show() scenario when i close the overall applicaiton it is not closed properly sometimes as the new form which is not seen but there in memory.
I've used Threads as well in the callback with new form in showdialog(), but even that behaves like a .show() now. and definite error of Null reference comes up when closing.
how can i make new form appear with returing from callback possible.
