dna	In this source Global NS#,SH# GRA_WID=800:GRA_HEI=600 Graphics GRA_WID,GRA_HEI,24,2 YRO=20:NR=200:RD=10:SP=GRA_HEI J=1 NS=(NR/ RD) SH=(SP/NS) .LP CH=0:Cls:Rect GRA_WID-20,((J-1)*SH)+YRO-20,15,SH-5,1 While CH=0 CH=GetKey() Wend If CH=28 And J>1 Then J=J-1:Goto LP If CH=29 And J<NS Then J=J+1:Goto LP If CH=27 Then End ;Wend Goto LP --v I have a problem with the code when the amount of files gets really large. How is this expression wrong? -=-=- DNA

rockford	I presume it's because you are using a GOTO within a loop If CH=28 And J>1 Then J=J-1:Goto LP If CH=29 And J<NS Then J=J+1:Goto LP Surely you only need to increase or decrease the J value - the loop is going back to .LP anyway?

dna	I removed the goto statement at the end of ch=28 and ch=29 and still got the same result. It might be the algorithm. NS in my source is 13000+ while SP always falls between 600 - 1080 -=-=- DNA

rockford	OK. What is this coded in (language Blitz etc.)? Is this the WHOLE code? What do you mean by "amount of files gets really large"? Do you mean you are checking with TaskManager and watching the filesize increasing? And SP should always be 600 (not even in a range) - that's what you've defined GRA_HEI as (GRA_HEI=600) (SP=GRA_HEI) and NR should always be 20 (NR=200:RD=10) NS=(NR/ RD) your SP and NS variables are not being changed after initialization in the code you've provided, so unless there is extra code your last statement is making no sense at all.

dna	The variables are not changing after the code is being run. This is not working properly with the variables you see here. You are right those defined variables do remain the same during the operation of the code. I was just thinking ahead since I MIGHT change them. This was compiled in B3D. -=-=- DNA

rockford	Still don't understand the whole "amount of files gets really large" bit though? This is not working properly with the variables you see here. What are you expecting to see and what is the actual result?

dna	Oh. The code is for some progress bars that would be similar to the ones you would find in your IDE when you program. As your press the down arrow the bar moves down progressively to show your location in the list or whatever you are use the code for. -=-=- DNA

steve_ancell	dna As your press the down arrow the bar moves down progressively to show your location in the list or whatever you are use the code for. That sounds more like a highlight bar rather than a progress bar.

Afr0	As your press the down arrow the bar moves down progressively to show your location in the list or whatever you are use the code for. You mean scroll bars? o.O If this is what you mean, I can pull some code from Project Dollhouse to show you As for your code - it is hopeless. I'm not going to bother trying to wrap my head around it, because you're using two and three letter variable names and purposefully circumventing indentation. -=-=- Afr0 Games Project Dollhouse on Github - Please fork!

dna	Yes its supposeed to be generic scroll bars.
Mon, 20 May 2013, 10:21
steve_ancell	I did some generic toolbars quite a few years back, may need inprovement but you are wecome to pull it apart and build on that. It's a bit shit but have a look anyway. homepage.ntlworld.com/stephen.ancell/downloads/files/tilemap_editor.zip
