From: kpg on 2 Jun 2010 17:28 Is there a utility out there that can scan my project files and tell if a control is being used (referenced in code)? I use MZTools to find dead code, but I want to find dead controls. Maybe MZTools can do it, I just don't know how. It wouldn't be too difficult to write something rough to do it myself, but something readymade would be nice. kpg

Well, VB does that automatically everytime it compiles. Unless you tell it not to. (Project-Properties-Make) Do you really have projects with so many controls, you're not sure if some of them are even used? -- ..NET: It's About Trust! http://vfred.mvps.org Customer Hatred Knows No Bounds at MSFT ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org

I knew someone would ask this question, and the answer is...Yes. I have a legacy app (ah, the absolution that comes when I say 'legacy') that has the maximum amount of controls, that is, the vb6 ide will not allow me to add any more. I really don't know what that number is (32767?) but I am there. This form is complex but functional. I believe that menu items count against the total, as do shapes (lines) used to create divides and borders, popup grids (frames and pictureboxes with multiple child controls) that exist multiple times so they can be pre-loaded when the app starts (when the app was first written machines were slow and navigation speed was more important than startup time or memory usage). Good design? heck no, In need of a re-write?, you bet, but that's not going to happen so I've got what I've got. Every control on the form is configured and moved at run time, so I'm safe to assume that if a control is not touched in code it is no longer used, hence my desire for a dead control sweep. I've got a utility I wrote long ago to find undeclared variables in QuickBasic code that does a fair job of building a symbol table from BASIC code, I could probably adapt that to do this task.

I meant 'used in code' as in controla on a forms that are no longer needed. |
