Entering Fractions in Dimensions Calculator

[mleblanc001]

Hi Gurus,
I have created a short script to plug in some dimensions for building frames for some paintings I purchased. This gave me an opportunity to create the painting dimensions calculator. The userform works well with decimals but when it comes to entering fractions it won't work. I've looked all over the internet to try to find a solution to not avail. Some places indicate a formatting of "#???/???" but I tried it and it didn't work. Does anyone have any idea how to resolve this? I'm at a loss. I'm attaching the file I've created for your and other member's information.

Thank you all

This assumes a single space between number and fraction "5 3/4", a decimal, integer or a fraction.



Dim PH, TR '.etc


Private Sub CommandButton1_Click()
TotalMattingOpeningHeight = PH + TR 'etc
End Sub


Sub Fractions()
PH = Convert(PaintingHeight)
TR = Convert(TopReveal)
'etc.
End Sub


Function Convert(x)
Dim Dim1, Dim2
If InStr(1, x, " ") Then
If InStr(1, x, "/") Then
Dim1 = Split(x)(0)
Dim2 = Split(Split(x)(1), "/")(0) / Split(Split(x)(1), "/")(1)
Convert = Trim(Dim1 + Dim2)
Else
Convert = Trim(x)
End If
Else
If InStr(1, x, "/") Then
Dim2 = Split(x, "/")(0) / Split(x, "/")(1)
Convert = Trim(Dim2)
Else
Convert = Trim(x)
End If
End If
End Function

Thank you so much mdmackillop for responding so quickly. Your script definitely enables me to enter fractions in the textboxes, however, I haven't been able to produce results in the total textboxes. Could you review my changes to see what I might be doing wrong. Thanks again for all the help.

Can you post appropriate numbers in a workbook that I can import into the form

Thank you

Just a matter of changing strings to numbers and sharing variables

Option Explicit

Dim PH As Single, PW As Single, TR As Single, BR As Single
Dim LR As Single, RR As Single, MB As Single, ES As Single
Dim RD As Single, TWOM As Single


Private Sub CommandButton1_Click()


Call Fractions

TotalMattingOpeningHeight = PH + TR + BR
TotalMattingOpeningWidth = PW + LR + RR
TotalInsideFrameHeight = PH + TR + BR + (MB * 2) + (ES * 2)
TotalInsideFrameWidth = PW + LR + RR + (MB * 2) + (ES * 2)
TotalCuttingHeight = PH + TR + BR + (MB * 2) + (ES * 2) + ((TWOM * 2 - RD) * 2)
TotalCuttingWidth = PW + LR + RR + (MB * 2) + (ES * 2) + ((TWOM * 2 - RD) * 2)

End Sub


Sub Fractions()
PH = Convert(PaintingHeight)
PW = Convert(PaintingWidth)
TR = Convert(TopReveal)
BR = Convert(BottomReveal)
LR = Convert(LeftReveal)
RR = Convert(RightReveal)
MB = Convert(MattingBorder)
ES = Convert(ExpansionSpace)
RD = Convert(DepthOfRabbet)
End Sub

Function Convert(x)
Dim Dim1, Dim2
If InStr(1, x, " ") Then
If InStr(1, x, "/") Then
Dim1 = Split(x)(0)
Dim2 = Split(Split(x)(1), "/")(0) / Split(Split(x)(1), "/")(1)
Convert = Trim(Dim1 + Dim2)
Else
Convert = Trim(x)
End If
Else
If InStr(1, x, "/") Then
Dim2 = Split(x, "/")(0) / Split(x, "/")(1)
Convert = Trim(Dim2)
Else
Convert = Trim(x)
End If
End If
End Function

Wow, This calculate the fractions perfectly. However, I noticed that the "Total" fields are still showing in decimals. I attempted to have them show as fractions but to no avail. Am I asking to much if you could show me how to convert those numbers to fractions as well. Thanks again for all your help.

[mdmackillop]

I've adapted code found here (http://www.freevbcode.com/ShowCode.asp?ID=582) to convert back to fractions. Some results in my test are different from yours as posted above.

Private Sub CommandButton1_Click()


Call Fractions

TotalMattingOpeningHeight = Dec2Frac(PH + TR + BR)
TotalMattingOpeningWidth = Dec2Frac(PW + LR + RR)
TotalInsideFrameHeight = Dec2Frac(PH + TR + BR + (MB * 2) + (ES * 2))
TotalInsideFrameWidth = Dec2Frac(PW + LR + RR + (MB * 2) + (ES * 2))
TotalCuttingHeight = Dec2Frac(PH + TR + BR + (MB * 2) + (ES * 2) + ((TWOM * 2 - RD) * 2))
TotalCuttingWidth = Dec2Frac(PW + LR + RR + (MB * 2) + (ES * 2) + ((TWOM * 2 - RD) * 2))

End Sub




Public Function Dec2Frac(ByVal f As Double) As String


Dim df As Double
Dim lUpperPart As Long
Dim lLowerPart As Long
Dim Num As Long
Dim Nom As Long

lUpperPart = 1
lLowerPart = 1

df = lUpperPart / lLowerPart
While (df <> f)
If (df < f) Then
lUpperPart = lUpperPart + 1
Else
lLowerPart = lLowerPart + 1
lUpperPart = f * lLowerPart
End If
df = lUpperPart / lLowerPart
Wend

Num = Int(lUpperPart / lLowerPart)
Nom = lUpperPart Mod lLowerPart


Dec2Frac = Num & " " & Nom & "/" & CStr(lLowerPart)
End Function

Thank you so much, it works great. I actually had found the Dec2Frac function online and attempted to make it work but forgot to include the Dec2Frac as part of the Call Fractions procedure. I made some minor changes, such as, adding some additional Total Fields and some colour. I am attaching the Final product. Thanks again for all your help. Greatly appreciated.

[mdmackillop]

I'm a little confused. Your final changes include removing the Dec2Frac utility. You could, of course have two buttons, one to return fractions, one for decimals. If you're content, please mark this solved.

[mleblanc001]

Hi mdmackillop,
Definitely content. Yes, you're right I could have two buttons, one for fractions and one for decimal but for my use, I only needed fractions. I want to thank you again for all your help on this. I'm not sure how to mark as resolved, how can I do that on this Forum?

Use the Thread Tools at the top of the thread. Since you asked so nicely, I did it for you this time. :)

[mleblanc001]

Great, thank you.
