multiforms closing problem

[oqapsking]

hello

in my hmi project
i have 6 pages

the first one is the main

it has 5 buttons each button opens a form

what i do is the other five forms have close button that closes them and return to the main page

the button code is

Code: [Select]

Me.Hide()
            mainpage.Show().

now when i run the application

i can go to tow pages
when i try to open a third page it gives me runtime error

so i need to close them not hide them

but when i try the code

Code: [Select]

Me.close()
            mainpage.Show()
or

Code: [Select]

Me.close()
           
 it gives an error too

so what is the best way to open the forms and close them


the open form code i use  is

Code: [Select]

page1.show()
with thanks

Use the open form button Archie made. That's the best/easiest.

the thing is am using multi panels each panel works as a thumbnail for its page

not buttons

so when i double click on the panel it opens its page
something like cameras software

Ok, regardless of what you use the code should be similar, if not the same.  Open Archies button and look at the code and use that.

this is archie code

Code: [Select]

f1.Show()
                f1.BringToFront()
it would give the same problem

Post more details in the error you are getting.

[oqapsking]

I will get them tommorow and post them here

[oqapsking]

the error comes as like this

i click to open the form it opens good
then i return to the main page

after that if i try to open any form

it gives the error in the attachments

note : all my forms are the same
the only thing is deferrent is the plc address and the form name
so they have the  same components and controls with the same name

could that be the problem?

Click the View Details and look for the first class and line number in the list which should be near the top.

I REMOVED THE IMAGELIST FROM ALL THE FORMS THEN I TRIED TO OPEN AND CLOSE FORMS AND IT WORKS FINE

SO AM GONNA PUT NEW LIST MABYE THE PROBLEM WAS IN COPYING THE PROMS AND JUST CHANGING THE FORM NAME
