List Sections from ini Files

CodeMonkey, First off, I would seriously consider using the registry for this, it would probably be easier... but to answer your question. GetPrivateProfileString allows you to pass NULL as a value for Parameters 1 and 2 (AppName and KeyName) If AppName is NULL then it returns the secion names in a list. If KeyName is NULL then it returns the keys of that section in a list. for example, if you had an ini file with :-



Square=10
Round=5
Oval=89


Red=1
Green=43
Blue=78

if you called GetPrivateProfileString with the AppName as NULL then the returned buffer would contain "SHAPESCOLOURS" If you called it with AppName being "SHAPES" and KeyName being NULL you will get :- "RedGreenBlue" Easy :) umbongo

List Sections from ini Files

CodeMonkey, I'm not quite sure I understand your question, but here goes... Here's an example piece of code


.data
	szAppKey	db	256 dup(0)
	szKeyName	db	256 dup(0)
	szDefault	db	256 dup(0)
	szResult	db	256 dup(0)
	szIniFile	db	"c:\test.ini",0

.code

start:
	invoke GetPrivateProfileString,NULL,addr szKeyName,addr szDefault,addr szResult,255,addr szIniFile

 c:\test.ini

contains :-



Square=1
Circle=2


Red=1
Blue=2
Green=3

then you will get this in szResult:- "SHAPES.COLOURS.." where the '.' means the NULL character so you need a pointer to the string, use the string at the pointer, then move it one byte past the NULL char, if it is pointing at a NULL again, it's the end of the string! like this :-


	lea	eax, szResult

l1:	push	eax
	invoke MessageBox,0, eax,addr szTitle,MB_OK
	pop	eax

l2:	inc	eax				; move along one char
	cmp	byte ptr ,0		; is it a NULL?
	jne	l2				; no, keep looping

	inc	eax				; it was a NULL, move along one more.
	cmp	byte ptr ,0		; is it a NULL again - if so we've finished
	jne	l1				; no, show this messagebox

which will display the names of the string it found... Hope this helps. umbongo
