Can't you just store the styleruns in an array? I don't know, it's been a
while since I used them...

Hi,
REALbasic 2006r4 running on Mac OS X 10.4.8 (but will be deployed on Linux
and Windows if possible)
I wanted to add to my simple text editor (small amount of text, else I use
- when possible - TextEdit or a true text processing software) the
LowerCase, UpperCase, TitleCase functions and so I started using LowerCase.
As usual (with newbies and people with memory indexing troubles), I forget
_the styles_ of the original text... See CODE #1.
Then, I wrote CODE #2 who gracefully takes care (store / restore) of the
text styles (Bold, Italic, ... TextName, TextSize, TextColor). But it takes
forever (see next paragraph) to convert 20 characters
The final code runs on around 36 Ticks for 20 characters
(ABCDEFGHIJKLMNOPQRST), each using one color different from the previous,
style also different from the previous (Plain, Bold, Italic), but only one
Font Name / Font Size (I was tired at that stage!)
My (simple) question is:
How can I get my code run faster ?
PowerBook G4, 15", 1.5GHz, RAM: 512MB
[Changing the machine is not an option]
I searched in the Language Reference, but I didn't saw anything that can
help me running faster or writting different code who achieve the same job.
Any taker for this challenge ?
[Also, an advice to code TitleCase is welcome; the code below is not
"usable" with TitleCase ;) !]
TIA,
Emile
CODE #1
-------
The code below was used to set LowerCase an EditField's selected text
(very fast):
Dim StartSel As Integer
Dim LenSel As Integer
// Get these three properties
StartSel = Me.SelStart
LenSel = Me.SelLength
// Set the change
Me.SelText = LowerCase(Me.SelText)
// Select back the changed text [re-select the text as it was prior the
case change]
Me.SelStart = StartSel
Me.SelLength = LenSel
CODE #2
-------
The code below seems to work fine, but takes "times" on only 20 characters
(think at a large document!):
//
// Change the case of the selected text to LowerCase
//
Dim StartSel As Integer // Position of the first selected Character
Dim LenSel As Integer // Number of selected Characters
Dim CharIdx As Integer // Loop indice
Dim EndSel As Integer // Top value of the Loop (meaningless name!)
// Used to store and restore the character styles
Dim sPlain As Boolean
Dim sBold As Boolean
Dim sCondense As Boolean
Dim sExtend As Boolean
Dim sItalic As Boolean
Dim sOutline As Boolean
Dim sShadow As Boolean
Dim sUnderline As Boolean
Dim sTextColor As Color
Dim sTextFont As String
Dim sTextSize As Integer
Dim TickStart As Double
Dim TickEnd As Double
TickStart = Ticks
// Get these three properties
StartSel = Me.SelStart
LenSel = Me.SelLength
EndSel = StartSel + LenSel
For CharIdx = StartSel To EndSel
// ------------------------- ----- ----- ----- -----
// CHANGE ONE CHARACTER CASE
// -------------------------
// Select one character at a time
Me.SelStart = CharIdx
// Set .SelLength to one character only
Me.SelLength = 1
// Save the Character properties
// a. Get the Character styles
sPlain = Me.SelPlain
If sPlain Then
// Do nothing, already done!
Else
sBold = Me.SelBold
sCondense = Me.SelCondense
sExtend = Me.SelExtend
sItalic = Me.SelItalic
sOutline = Me.SelOutline
sPlain = Me.SelPlain
sShadow = Me.SelShadow
sUnderline = Me.SelUnderline
End If
// b. Set the Text styles
sTextColor = Me.SelTextColor
sTextFont = Me.SelTextFont
sTextSize = Me.SelTextSize
// Set the change (one character at a time)
Me.SelText = LowerCase(Me.SelText)
// ------------------------- ----- ----- ----- -----
// SET THE CHARACTER STYLES BACK
// -----------------------------
// Select one character at a time
Me.SelStart = CharIdx
// Set .SelLength to one character only
Me.SelLength = 1
// Restore the Character properties
// a. Set the Character styles
If sPlain Then
Me.SelPlain = sPlain
Else
Me.SelBold = sBold
Me.SelCondense = sCondense
Me.SelExtend = sExtend
Me.SelItalic = sItalic
Me.SelOutline = sOutline
Me.SelShadow = sShadow
Me.SelUnderline = sUnderline
End If
// b. Set the Text styles
Me.SelTextColor = sTextColor
Me.SelTextFont = sTextFont
Me.SelTextSize = sTextSize
Next
// Select back the changed text [re-select the text as it was prior the
case change]
Me.SelStart = StartSel
Me.SelLength = LenSel
TickEnd = Ticks
MsgBox "Duration: " + Str(TickEnd - TickStart) + " (in Ticks)"
