Search And Find

Hello, fellow coders,
I've gotten some powerful code from here, yet I've got Soooo much to learn. Can anyone tell me how to make the following code stop at each find, instead of shooting through the whole search without stopping? This code simply totals up the amount of times the search text was found and turns them all red. I expect it to be simple, but simple is hard when you don't know what it is. Thanks in advance.

Option Explicit
Option Compare Text

Private Sub Command2_Click()
unload me
End Sub

Private Sub Form_Load()

RichTextBox1.LoadFile "MyFile.wav"

End Sub

Private Sub Command1_Click()

Dim strval As String 'Inputbox returns a string
Dim nStrings As Long
RichTextBox1.LoadFile "MyFile.wav"
strval = " " & InputBox("Enter the string to find.", "Findit", _
"Love") & " "

If strval <> "" Then

nStrings = FindIt(RichTextBox1, strval)
MsgBox (Str$(nStrings + 1) & " instances of """ & strval & """ found.")

End If

End Sub

Private Function FindIt(Box As RichTextBox, Srch As String, _
Optional Start As Long)

Dim retval As Long 'Instr returns a long
Dim Source As String 'variable used in Instr

Source = Box.Text 'put the text to search into the variable

If Start = 0 Then Start = 1 'the initial call doesn't pass a value
'for Start, so it will equal 0

retval = InStr(Start, Source, Srch)

If retval <> 0 Then

With Box
.SelStart = retval - 1
.SelLength = Len(Srch)
.SelColor = vbRed
.SelBold = True
.SelLength = 0
End With

Start = retval + Len(Srch)

FindIt = 1 + FindIt(Box, Srch, Start)

End If
End Function

This isn't an answer to your question but I just wanted to point out that this code will cause you problems.

VB Code:

Private Sub Command2_Click() 
End 
End Sub

Instead of using End you should just unload all your forms.

Thanks for your advice, Martinliss. I've changed the code from "End" to "Unload Me".

It is at this point:

VB Code:

If retval <> 0 Then 
    With Box 
                'etc
    End With 
    Start = retval + Len(Srch) 
'Now we re-call the function to find the next occurrence of the string
    FindIt = 1 + FindIt(Box, Srch, Start) 
End If

So, just befre you call "FindIt" again, you can do things to pause the program (Msgbox "Click to Continue")

Thanks, JordanChris

Your code worked well. How can I replace the msgbox with a next button so that it would work like a regular search routine and stop at each highlighted find? Thanks in advanced to anybody who would respond.

Instead of using the Find method of the richtextbox, i use while loops to search the text and colorize it/count it. Tis how i made my error report for my programming language. Here's how i'd do that:

VB Code:

Option Explicit 
Dim Position As Integer
Dim found As Integer
 
Private Sub Command2_Click() 
unload me 
End Sub 
 
Private Sub Form_Load() 
 
RichTextBox1.LoadFile "MyFile.wav" 
 
Position = 0
 
found = 0
 
End Sub 
 
Private Sub Command1_Click() 
 
Dim strval As String 'Inputbox returns a string 
Dim nStrings As Long 
RichTextBox1.LoadFile "MyFile.wav" 
strval = " " & InputBox("Enter the string to find.", "Findit", _ 
"Love") & " " 
 
If strval <> "" Then 
 
FindIt RichTextBox1, strval
MsgBox (found & " instances of """ & strval & """ found.") 
 
End If 
 
End Sub 
 
Private Function FindIt(Box As RichTextBox, Srch As String) 
 
Position = InStr(Position + 1, Box.Text, Srch, vbTextCompare)
 
While Position > 0
Box.SelStart = Position - 1
Box.SelLength = Len(Srch)
Box.SelColor = RGB(255, 0, 0)
found = found + 1
Position = Position + Len(Srch)
Position = InSTr(Position + 1, Box.Text, Srch)
Wend
 
End Function

Hope that helps

Throw these lines at the end of the function away:

VB Code:

'Now we re-call the function to find the next occurrence of the string
    FindIt = 1 + FindIt(Box, Srch, Start)

Then you are all set....

But there is a little extra programming to do first!
You need the variable Start to be globally available (DIM it at the top of your program, or in a code module), so that you can call FindIt with the Start parameter each time the user clicks on "Find Next".

Make sure you know what the user wants when clicking on "Find". Do they mean: start where I have got to and look further. Or do they mean: start at the beginning and look from the beginning.

You may well need a Find and a Find Next button. The FindNext button should [probably] only be visible after the Find button has been clicked. Should it also be available when the user has got to the end of the FindNext loop?

LoL, took me 10 minutes to type that, why didnt i copy it??

I agree with jordan, have a Find and Find Next Button...alot easier..

Yes, in most applications, Find Next is visible at the same time as Find...

Hey Guys,
I can't seem to get this thing to work. Can anybody fix this code and post a working copy? I keep getting errors and as I try to fix one, I get another. What I would like is a code that allows me to search a rich text box and find EVERY occurrence of a string and not miss any. I need it to stop at each find and turn it red. It would be nice to give the total amount of finds at the beginning of the search and then count down as the we go. I know that this is simple for some of YOU guys. It is just hard for me. I will never come close to being a rocket scientist, but I love to program. This stuff fascinates me. Thanks in advanced.

Dear all,
Just wondering what if I would like to seach back my data in the sql database. At present what I did was I have created some forms where the user will enter the information in the textbox and submit the data to be saved in the sql database server. What I want is for the user to be able to search back the data by using a unique key for example. Is that possible? Please advice..thanks in advance.
