Sorry about that last one.
Does anyone know how to calculate the width a string of text for given Font
name and size?
I want to buildup a block of text strings to display in a unbound control,
that has limited width but multiple lines. Currently I am using the left$()
function to trim the text to a standard number of characters. I want a
function to return the number of characters that will fit in the width of
the control. To keep the output nice, I don't want to use a fixed pitch
font.

Try something like this (Access 2003) in a format event of a report
Private Sub GroupHeader0_Format(Cancel As Integer, FormatCount As Integer)
Dim lChangeLength As Long
With Me
.FontBold = True
.FontItalic = True
.FontSize = 12
.FontName = "Times New Roman"
End With
lChangeLength = Me.TextWidth(Me.AssignmentCompany)
'MsgBox lChangeLength
Me!AssignmentProject.LeftMargin = lChangeLength + 100
End Sub
This sets the relevant font for measuring the width of the field and
TextWidth returns the value in the scale set for the report.
The final line actually uses the value to display an offset for another
field so that the two fields appear in different formats at a set distance
apart no matter what the data being displayed is.

Of course I may have answered a different question. Ooops! (g)

I'm pretty sure I know everything that I can remember.
I tried Stephen Lebans TextHeightWidthVer45.mdb database with the function
GetLeftQty() to calculate the number of characters that will fit into the
control.
fTextWidth() sometimes underestimates the TWIPS causing my character count
to be high. and other times overestimates the TWIPS causing my character
count to be low.
Public Function GetLeftQty(ctlr As Control, strTxt As String, lmax As
Integer) As Integer
' Function returns the number of character of strTxt that will fit in 1
line of control ctlr
Dim iLen As Integer ' Text length
Dim lngTextWidth As Long
Dim ctlW As Long
ctlW = ctlr.Width
iLen = Len(strTxt)
If lmax > 0 Then
iLen = MinV(iLen, lmax)
End If
Do While iLen > 1
lngTextWidth = fTextWidth(ctlr, Left$(strTxt, iLen))
' Does text fit? If yes then exit
If lngTextWidth < ctlW Then Exit Do
' Decrease text length
iLen = iLen - 1
Loop
If iLen > 2 Then
iLen = iLen - 2
End If
GetLeftQty = iLen
'Debug.Print iLen & ", " & fTextWidth(ctlr, Left$(strTxt, iLen)) & ", "

Yes,
The text is normally a persons name followed by a ":" and then some
information.
ex. I would pass the function text one line at a time adding the result to
the control
..21
Doe, John: 8 Hours Vacation
Walacs, Henry: 8 Hours Vacation
Clar, Sue: 8 Hours Vacation
May come back like this
..21
Doe, John: 8 Hours Vacation
Walacs, Henry: 8 Hours Vacation
Clar, Sue: 8 Hours Vacation
It looks like longer strings return fewer Twips.

On further study, fTextWidth() underestimates the TWIPS with my font
settings by 1-2 characters. My subtracting 2 characters just made it look
like an overestimate.
Font Name: MS Sans Serif
Font Size: 8
Font Weight: Normal
Font Italic: No
Font Underline: No
Text Align: General
Width: 1.7854"
Height: 1.1458"
I tried the following change, which gave me the same results as the supplied
code.
lngRet = apiDrawText(hDC, sText, -1, sRect, DT_CALCRECT Or DT_BOTTOM Or
DT_LEFT Or DT_EXTERNALLEADING Or DT_NOCLIP Or DT_SINGLELINE)

Well I found a solution for my application. Increase the TWIPSERINCH
constant from
Private Const TWIPSPERINCH = 1440
To
Private Const TWIPSPERINCH = 1600
This gave me much finer control than reducing the character count in
GetLeftQty().
I would like to thank Stephen Lebans for very useful function.

The solution is not to change an intrinsic constant. You are now tied to the

You use WidthTwips = .Right * (TWIPSPERINCH / lngDPI) to calculate width. Is
GetDeviceCaps returning the wrong value? If so, what problems would I have
if lngDPI is adjusted for this calculation?

the current resolution setting of your graphics card.

You are right!
I modifyed GetLeftQty() to calculate the number of twips for the character
"X" and used that to reduce the number width of the control in the loop
Public Function GetLeftQty(ctlr As Control, strTxt As String, lmax As
Integer) As Integer
On Error Resume Next
' Function returns the number of character of strTxt that will fit in 1 line
of control ctlr
Dim iLen As Integer ' Text length
Dim lWidth As Long ' Adjusted control width
iLen = Len(strTxt)
If lmax > 0 Then
iLen = MinV(iLen, lmax)
End If
lWidth = ctlr.Width - fTextWidth(ctlr, "X") ' Reduce control width by 1
character.
If lWidth < 1 Then
GetLeftQty = 1 ' Return 1 if adjusted control width is < 1 Twip
Exit Function
End If
Do While iLen > 1
' Does text fit? If yes then exit
If fTextWidth(ctlr, Left$(strTxt, iLen)) < lWidth Then Exit Do
' Decrease text length
iLen = iLen - 1
Loop
GetLeftQty = iLen
End Function | | This discussion thread is closed Replies have been disabled for this discussion. Similar topics
