It's a string of Dec values created by passing the original HexString (or Hex digits, as you say) to Excel's Analysis Toolpak Hex2Dec() function. For the record, Chr$(14) returns "", same as does Chr$(&H0E). The point of the exercise is to duplicate what Excel's Hex2Dec() does using VB[A]. What concerns me is the user claims to get different result for Chr$(&H0E), reporting that it returns "3045"!<???> I suspect he's using either a custom Hex2Dec() function, or a custom Chr() function, or both. regards, -- Garry Free usenet access at http://www.eternal-september.org ClassicVB Users Regroup! comp.lang.basic.visual.misc

Not going to work for all pairs as does using '256'. Results using "0" instead of '256': Original hexString: "0E0E00000505000C20450164A5A5" Returns DecString: "14,14,0,0,5,5,0,12,32,69,1,100,165,165" Restore DecString returns: "EE00550C2045164A5A5", which is not what we want. regards, -- Garry Free usenet access at http://www.eternal-september.org ClassicVB Users Regroup! comp.lang.basic.visual.misc |
