opening form

[tek1ket]

i have 2 forms in my app. at first form1 should be opened by which i can select which projects i want to work on. for openning the form2 (which contains all data related to selected project) i have used this code

MainMDI myForm=new MainMDI();
myForm.Text=lstProject.Text;
myForm.IdProj=IdProject;
myForm.Show();
this.Hide();

which i don't whether is a good idea or not.
now in form 2 i have a menu named "Open a Project", by clicking on the form1 should be opened again and the selected projected's been changed, so all data in form2 should be changed also, the probelm is here:

a new instance of form2 with data of new selected projected is opened.which i want it should be shown on first instance of form2.

thank you fro your help.

Look into delegates for communication between forms. There are plenty of examples online.
