a tricky questions

[mooose]

Howdy everyone

ok the first question I don't really know how to explain so I'll have to use an example:

ok say I was getting my program to search the hard drive for a file say mooose.ocx ok now say it came back with 50 matches and I wanted it to write this data to the registry
I write to the registry like so:
SetStringValue "HKEY_LOCAL_MACHINE\software\moose inc\what ever the programs name", "title of string", "then the string" so instead of make 50 if statements to cope with 50 matches is there someway to just make 1 if statement that will write how many ever files are found paths to the registry?

so it would look like this:
SetStringValue "HKEY_LOCAL_MACHINE\software\moose inc\search", "match1", "C:\programs files\mooose.ocx"
SetStringValue "HKEY_LOCAL_MACHINE\software\moose inc\search", "match2", "C:\programs files\mooose\mooose.ocx"
and so on just adding another number to the match and listing the path like above?

and also a slight variation of the question above so to read from the registry I would read from it like so: GetStringValue("HKEY_LOCAL_MACHINE\software\Mooose Inc\search", "match")
so what i want to know also is how would I get say all the values out of the registry into a list box so instead of having to type another 50 statements to get each file. so how would i do those things?

thanx

Here you are Moose:

Option Explicit

Private Sub Command1_Click()
Dim i As Integer

For i = 0 To 5
SaveValue "match" & i, "something " & i
Next i
End Sub

Private Sub Command2_Click()

Dim Names() As String
Dim Values() As String


KeyCount = EnumRegValue(HKEY_LOCAL_MACHINE, ROOT_REG_KEY, Names, Values)
For i = 0 To KeyCount - 1
List1.AddItem Names(i) & " " & Values(i)

Why use the registry?
try this code:
---
In a command button

List1.Clear 'Files put here
List2.AddItem "C:\" 'Invisible list of dirs
Do
findfilesdir lstdirs.List(0), "moose.ocx" 'search pattern
List2.RemoveItem 0
Loop Until List2.ListCount = 0

In the forms general | declaration

Public Sub findfilesdir(DirPath As String, FileSpec As String)
Dim filestring As String
Dim SearchFileName As String

DirPath = Trim$(DirPath)

If Right$(DirPath, 1) <> "\" Then
DirPath = DirPath & "\"
End If

filestring = Dir$(DirPath & FileSpec, vbArchive Or vbHidden Or vbSystem Or vbDirectory)
Do
DoEvents
If filestring = "" Then
Exit Do
Else
If (GetAttr(DirPath & filestring) And vbDirectory) = vbDirectory Then
If Left$(filestring, 1) <> "." And Left$(filestring, 2) <> ".." Then
List2.AddItem DirPath & filestring & "\", 1
End If
Else
SearchFileName = DirPath & filestring
End If
End If
If InStr(SearchFileName, Text1.Text) Then List1.AddItem SearchFileName
filestring = Dir$
Loop

End Sub

Good luck!
P.S.This was taken from this site 'tweaked' a litle bit.
