[AccessD] Looking at lines of code in code

Dear List:
 
I have a need to programmatically look at every line of code behind all
forms looking for the string "TranslateMsgbox".
 
I'm floundering around here a bit.  I know how to cycle through the forms
collection.  But once I open the form in design view and Set frm =
Forms(strFormName) I can't figure out how to loop through every line of code
behind the form.  
 
Any suggestions appreciated.
