First letter on each sentence UCase

hi
i need some help to make text in textbox change to first letter on first word in a sentence UCase.
im a trying to do this: You input Text into a Text Box, you click a radio button, then you click a convert text cmd and it changes the text in the text box to first letter on first word in a sentence UCase.
I have done first letter on each word upper case which was

Code:

---

Option Explicit

Private Sub Command1_Click()
    MsgBox makeFirstUCase("hello i aM aaRon")
End Sub


Private Function makeFirstUCase(myStr As String) As String
    Dim strArr() As String
    Dim i As Integer
   
    strArr = Split(myStr, " ")
    For i = 0 To UBound(strArr)
        If strArr(i) <> vbNullString Then
            strArr(i) = UCase(Left$(strArr(i), 1)) & Right$(strArr(i), Len(strArr(i)) - 1)
        End If
        makeFirstUCase = makeFirstUCase & strArr(i) & " "
    Next
   
   
   
End Function

---

Please help :)

if this is the result that you want Hello I Am Aaron then you may use this code

vb Code:

Private Function makeFirstUCase(myStr As String) As String
    Dim strArr() As String
    Dim i As Integer
    strArr = Split(myStr, " ")
    For i = 0 To UBound(strArr)
        If strArr(i) <> vbNullString Then
            strArr(i) = UCase(Left$(strArr(i), 1)) & LCase(Mid$(strArr(i), 2))
        End If
        makeFirstUCase = makeFirstUCase & strArr(i) & " "
    Next
End Function

thanks but i wanted the result of:
that dog is very lazy. it should go for a run! why is it tired? to
That dog is very lazy. It should go for a run! Why is it tired?

you need to search any character that can end sentance, followed by space, try like this

vb Code:

pos = instr(text1.text, ". ")
do while pos > 0
  text1.text = left(text1.text, pos +1) & ucase (mid(text1.text, pos +2, 1)) & mid(text1, pos +3)
  pos = instr(pos +1, text1.text, ". ")
loop

followed by similar loops for ? ! and other possible sentence endings
this will fail for any sentence /word enclosed in quotes, so you may need to test for quotes in each case, also words following an abbreviation may also be an issue
eg Dr. or Mr., though in both those case capitalising the next letter is probably fine, but in some cases may not

You will probably have to check for acronyms too.

you need to first determine what could be the end of the sentence in your case it is "." & "!" & "?" .now u need to loop thru until u find these characters and convert the next letter after a space to ucase (proper sentence structure)
try this code

vb Code:

Private Sub Command1_Click()
 MsgBox convTxt("that dog is very lazy. it should go for a run! why is it tired? oh my god are u serious?")
 
End Sub
 
Private Function convTxt(strTxt As String) As String 'strTxt
    
    Dim strconst As String
    'determine the character that could be the end of a sentence
    strconst = ".!?"
    
    Dim strone As String
    Dim y As Integer
    Dim strTwo As String
    Dim x As Integer
    'go thru each character
    For x = 1 To Len(strconst)
        strTwo = Mid$(strconst, x, 1)
        y = 0
        
        Do
            
            y = InStr(y + 1, strTxt, strTwo)
            strone = Mid(strTxt, y + 2, 1)
            If y = 0 Then Exit Do
            
            'convert to ucase
            strTxt = Replace(strTxt, strTwo & " " & strone, strTwo & " " & UCase(strone))
        Loop
    Next
    'convert first letter of the sentence to ucase
    convTxt = UCase(Left$(strTxt, 1)) & Mid(strTxt, 2)
End Function

Maybe:

MsgBox StrConv("that dog is very lazy. it should go for a run! why is it tired?", vbProperCase)

vbProperCase option will capitalize first letter of each word:
"That Dog Is Very Lazy. It Should Go For A Run! Why Is It Tired?"

There must be something like convert to "Sentence case" in MS-Word.

There is.

Short of that, here's another version of a sentence case function I posted last year:

Code:

---

Public Function SentenceCase(pstrText As String) As String
    Dim i As Long
    Dim bytArray() As Byte
    Dim blnUpper As Boolean
   
    blnUpper = True
    bytArray = StrConv(pstrText, vbFromUnicode)
    For i = 0 To UBound(bytArray)
        Select Case bytArray(i)
            Case 33, 46, 63 ' exclamation point, period or question mark
                blnUpper = True
            Case 65 To 90, 97 To 122
                If blnUpper Then
                    bytArray(i) = Asc(UCase$(Chr$(bytArray(i))))
                    blnUpper = False
                End If
        End Select
    Next
    SentenceCase = StrConv(bytArray, vbUnicode)
    Erase bytArray
End Function

Aaron, this code seems to have some promise. Build a form with a command button and a text box.

Code:

---

Dim MyString As String
Private Sub Command1_Click()
Mid$(MyString, 1, 1) = UCase(Mid$(MyString, 1, 1)) ' Cap first letter
Dim Pointer As Long
Do While Pointer < Len(MyString)
    Pointer = Pointer + 1
    Select Case Asc(Mid$(MyString, Pointer, 1))
    Case 33, 46, 63 ' Found end of a sentence
        If Pointer < Len(MyString) Then
            Pointer = Pointer + 1
            Do While Mid$(MyString, Pointer, 1) = " " And Pointer < Len(MyString)
                Pointer = Pointer + 1
            Loop
            ' Cap first letter of next sentence
            Mid$(MyString, Pointer, 1) = UCase(Mid$(MyString, Pointer, 1))
        End If
    Case Else
    End Select
Loop
Text1.Text = MyString
End Sub

Private Sub Form_Load()
' Sample collection of sentences
MyString = "cap me... please cap me? now cap me! Don't have to cap me; OK as is!..."
Text1.Text = MyString
End Sub

This is my version. I want to make it as close as possible to an MS-Word's method, it also covers Unicode characters.

Moved to CodeBank.

Terrific, anhn, but I notice that you are starting by converting all text to lower case before you start and that would seem to add a bit of complexity, thus turning the code into somewhat of an expert grammar/spell checker.

To me, that means that if the user wanted caps here and there, such as VB coded variables (e.g., SentenceCase above) that these caps would be eliminated. Please corect me if wrong.

I really do like the way this code handles the non-breaking space, wordwrap, and when the sentence starts immediately on a line after a hard return. I forgot about those instances. :thumb:

Any way we use will have some limitations. Without converting to lowercase first such as in case of all UPPERCASE, after calling SentenCase() the text is still in all UPPERCASE. That cannot be called Sentence Case.
Check to see how MS-Word change case to Sentence Case.

If you want to emulate Word, don't forget about the ellipsis. (...) It appears that Word leaves any text after an ellipsis in the same case it started. This won't work if you convert everything to lower case to start.

EDIT: The behavior changes if the text is all uppercase to start. The "leave it as it was" only applies to mixed-case text.

This may be off the wall! But can you not exploit what is used by MS word as this deals with all these issues already ?

Davadvice - You mean an API that Word uses?

My Version...

Try This :)

Code:

---

Sub ConvertToSentenceCase()
Dim TestString As String, strg2 As String
TestString = "wake me up before you go go. i want to have my breakfast! don't forget."

'test the 1st 10 chars to get the first - incase the selection includes
'some spaces at the beginning.
For X = 1 To 10
  strg2 = Mid(TestString, X, 1)
  If strg2 Like "[a-zA-Z]" Then
    Mid(TestString, X, 1) = UCase(strg2)
    Exit For
  End If
Next X

'test criteria (.!?) for the end of a sentence, then Capitalize the next letter.
For X = X To Len(TestString)
  strg2 = Mid(TestString, X, 1)
  If strg2 Like "[.!?]" Then
    For Y = X + 1 To X + 10
      strg2 = Mid(TestString, Y, 1)
      If strg2 Like "[a-zA-Z]" Then
        Mid(TestString, Y, 1) = UCase(strg2)
        X = Y + 1
        Exit For
      End If
    Next Y
  End If
Next X

'This will give you the result
MsgBox TestString

End Sub

yeah, if the API will allow access to the area responsable for performing this action in Word then is there no way this can be used ?

I know that in Access there is the function to auto spell check then i asume Words API will allow a call to pass a string and return the formated text.

thus no need to reinvent the wheel as such ?

thanks
