SSAFE1/26/2023

and please remove the commented out duplicate code, it just makes reading really hard

PPobiega1/26/2023

at a glance, it seems okay. Are you sure the Form1_Load event is firing? use the debugger to make sure

SSAFE1/26/2023

ok ill try, also maybe its cause i havent got to a certain part of assignment yet where i have to do something else to add it idk

SSAFE1/26/2023

yes it form loads

SSAFE1/26/2023

but the combox has nothing

PPobiega1/26/2023

read that again

PPobiega1/26/2023

I didn't ask if the form loads. I asked if Form1_Load actually triggers.

PPobiega1/26/2023

If you have not wired up the event subscription for that method, it wont.

SSAFE1/26/2023

um.. how can i tell if it triggers

SSAFE1/26/2023

im new ish sorry

SSAFE1/26/2023

or could i just copy my code into a second downloaded copy of the starter file and it would work?

PPobiega1/26/2023

You would use your debugger.

PPobiega1/26/2023

Set a breakpoint in visual studio

PPobiega1/26/2023

$debug

SSAFE1/26/2023

ok so i believe that it is triggering

AACiDCA71/26/2023

can you amke a screenshot of how the brakpoint was reached inside LoadGenres

AACiDCA71/26/2023

because your last message doesnt sound really convincing

SSAFE1/26/2023

ok sure

SSAFE1/26/2023

also i just download the assignment starter again and copied everything and it still wont show the combobox list, so its the code i think but idk lol

SSAFE1/26/2023

all was the same but that

SSAFE1/26/2023

SSAFE1/26/2023

loadgenres method

AACiDCA71/26/2023

you are just showing your code.. i wanted you to show me that the breakpoint in the right spot is getting reached.. for that you have to start your app

AACiDCA71/26/2023

the red dot should go into loadgenre

SSAFE1/26/2023

thought you meant breakpoint in the code, what do you mean

SSAFE1/26/2023

AACiDCA71/26/2023

now that its in there start your app

SSAFE1/26/2023

nothing in the combobox still

SSAFE1/26/2023

i put the dot at line 83 at the loadgenres method

AACiDCA71/26/2023

if you havent noticed any "weird" behavior i guess the method is never called

AACiDCA71/26/2023

that means the form_load method is never excecuted

AACiDCA71/26/2023

which means you have messed something up in the designer of the form

SSAFE1/26/2023

omg im dumb

SSAFE1/26/2023

i just double click form on the designer

SSAFE1/26/2023

so it would actually show up

AACiDCA71/26/2023

could you phrase it so that people who arent sitting right next to you understand what you mean

SSAFE1/26/2023

LOL

SSAFE1/26/2023

one more thing in it that needs to be fixed: '

SSAFE1/26/2023

SSAFE1/26/2023

shows that it isnt valid no matter what

AACiDCA71/26/2023

i see that genre is populated now... for that problem someone else can help you if you need more assistance

SSAFE1/26/2023

alright okok
