How to search a textbox for listbox items.(Solve)

Hi, I know how to search a listbox for an item on a texbox, but now I need to search a textbox for any for items locoted in a listbox.

so lets say if a listbox has, one, two, three

and in the textbox there is a sentence as such

"the number one"

then the program should msgbox word found.

thanks :)

You should be using Instr$() function. Something like this

VB Code:

If InStr$(Text1.Text, List1.List(1)) > 0 Then
    MsgBox "List Item is present in the text box"
End if

Not all that many ways to go:

VB Code:

Dim strText As String, lngA As Long
    ' store into temporary string variable for faster access
    strText = Text1.Text
    ' loop!
    For lngA = 0 To List1.ListCount - 1
        If InStr(strText, List1.List(lngA), vbTextCompare) > 0 Then
            MsgBox "Found!"
            Exit For
        End If
    Next lngA
    If lngA = List1.ListCount Then MsgBox "Not found!"

Shuja Ali: you shouldn't use $ character within InStr, because the return value is a Long and if you use $, the return value is first converted to a string and then to something else for numeric comparison.

well here's one way it could be done:

VB Code:

Dim N As Long
    
    For N = 0 To List1.ListCount
        If InStr(Text1.Text, List1.List(N)) Then _
            MsgBox "Found: " & List1.List(N)
    Next N

but what approach you actually take depends entirely on the specific circumstances of what you want to do. For example: do you want whole / partial words? is there punctuation?

you might want to also consider searching for Regular Expressions.

Okie I try this one first :)

VB Code:

Dim strText As String, lngA As Long
    ' store into temporary string variable for faster access
    strText = Text6.Text
    ' loop!
    For lngA = 0 To List5.ListCount - 1
        If InStr(strText, List5.List(lngA), vbTextCompare) > 0 Then
            MsgBox "Found!"
            Exit For
        End If
    Next lngA
    If lngA = List5.ListCount Then MsgBox "Not found!"

but i get a type mistmatch error on this line

VB Code:

If InStr(strText, List5.List(lngA), vbTextCompare) > 0 Then

let me check the others and see
Thanks guys

the VB IDE won't even let you do it - it automatically removes the $ for you.

Aigh I try using

VB Code:

Dim N As Long
    For N = 0 To List5.ListCount
        If InStr(Text6.Text, List5.List(N)) Then _
            MsgBox "Found: " & List5.List(N)
    Next N

it almost works perfect, but it somehow also looks for empty spaces, I think cause it also sends a message of Found: like that without any words
:rolleyes:

ah I looking to match either words or phrases :)

You must do ListCount - 1 and also check if the value is above 0, because -1 is reserved for error messages.

in post #7 (and in my orig post #4) it should be List5.ListCount - 1.

In fact, you should have got an error - oh well

I think you'd actually be much better off using Regular Expressions.

I usually write $ for almost all the string functions (this is a habit I have rright from Qbasic days), and this is what you get when you write code without VB IDE. :confusion:

Thanks guys now it works great i ended up using

VB Code:

Dim N As Long
    For N = 0 To List5.ListCount - 1
        If InStr(Text6.Text, List5.List(N)) Then _
            MsgBox "Found: " & List5.List(N)
    Next N

Thanks :)
