By adding 0's to the beginning of the string created by the Hex
funciton, it messes with the actual byte alignment.
For instance Red would be &HFF (or FF). You add 4 0's to the
beginning of it(because it is less then 6 chars long). That
changes it to blue(&H0000FF).

You need to try something like this:

Code:

Function MakeHex$(SomeColor As Integer)
	MakeHex$ = Right$("0" & Hex$(SomeColor), 2)
End Function

rgbColor = cca.rgbResult

RGBRed = rgbColor And &HFF
RGBGreen = ((rgbColor And &H100FF00) / &H100)
RGBBlue = (rgbColor And &HFF0000) / &H10000

htmlColor = "#" & MakeHex$(RGBRed) & MakeHex$(RGBGreen) & MakeHex$(RGBBlue)

No need to go out of your way to add leading zeroes. HEX$ can do that for you...

Code:

result$ = HEX$(number, fieldlen)

You learn something new every day. I didn't know you could do that.

Interesting results:

'

Code:

Function GetColorSelection(hWnd As Long,ByVal CurrentColor As String) As String
Local ColorValue    As Long
Local sTmp          As String
CurrentColor = Remove$(CurrentColor,"#")
ColorValue = SelectColor(hWnd,Val("&h" & CurrentColor),1)
If IsTrue ColorValue Then Function = "#" & Hex$(ColorValue,6)
End Function

If I click on Light blue, 5th one from the left on the top row in the color picker, it returns:
#FFFF80

But, The TNGMP3 Output shows this for folder background:
<TD BGCOLOR=#FFFF80>
So that is correct, except the CGI display is YELLOW:

'
'
Now, it may also be something with the dynamic style sheet that is being used, whereas LINK is defined in teh style as another color, but it's BACKGROUND is not.
Best way to show you is to have you browse to the CGI:
http://www.tngbbs.com/mp3/tngmp3.exe

username: powerbasic
password: powerbasic
domain: tngbbs

According to the source, it's supposed tdo be light blue, but the folderbg is yellow....
Basically here's what a "View->Source" shows:

Code:

The duplicate "Style" is because it's in a function called "MakeTNGBBS", I may remove that out and retest...
SOmething tells me the browser is confused, I understand that TABLE colors take precidence but it appears it is mixing the colors with the STYLE color.
The table ONLY contains hypertext links, and those are the only one's that are confused.
The tables that don't contain hypertext links are working correctly...

**Mark A Owiesny** · 11 May 2001, 02:03 PM

To do it the way Mr. Hanlin suggested, you would need to do
Left$(Hex$(ColorValue,8),6). It seems Hex goes from Right to
Left. If you have &H00FFFF80 or 16777088 you get:
Hex$(16777088, 6) FFFF80
Hex$(16777088, 8) 00FFFF80

As a side note, the earlier routine I posted was from some
VB code I did a while back. VB's Hex function isn't as
Smart as PB's. Hence creating the long routine I posted
earlier.

I believe you are right, because no matter how I do it blue comes up pink...and vice versa.

I'll give that a shot, gonna be tied up for a few days so I may post a new one sunday evening...

Thanks!

What does the RGB built in PB function do exactly?

Would it do what I need done here?

**Scott Turchin** · 11 May 2001, 03:09 PM

PS, THIS WORKS AWESOME!!!

With one exception that when entering the color picker it shows theREVERSE color that it used to show on the web page.

How do I convert DARK BLUE for example, so that when I ENTER the Color Picker it knows to go to that color.
Current dark Blue is #000080 (Navy blue)

It shows up as black or pink...

I have the extended colors extended automatically, cca.Flags = %CC_RGBINIT Or %CC_FULLOPEN Or %CC_ANYCOLOR ,

So....almost there... I don't quite understand but I do understand that each two digits is a %red,%green,%blue hex form....

Scott, maybe the same problem I had awhile back, Semen helped me out with this one.

What the choose color dialog returns is BGR, not RGB. The PB RGB function will convert
the 3 parameters to BGR format.

In the code fragment below, I store a text based color as RGB, so I have
to reverse the order returned from the choose color dialog.

Code:

    'First check for the Choose Color dialog...
    IF pItem(curSel).nItemType = %PIT_COLOR  THEN
  
        currClr = pItem(curSel).curValue
  
        IF  currClr > "" THEN
 
            'parse the property's current color value
            d$  = ","
            currClr = LTRIM$(currClr,"RGB(")
            currClr = RTRIM$(currClr,")")
            rv%     = VAL(Parse$(currClr,d$,1))
            gv%     = VAL(Parse$(currClr,d$,2))
            bv%     = VAL(Parse$(currClr,d$,3))
 
            initClr = RGB(rv%,gv%,bv%)
        ELSE
            'use a default instead
            initClr = RGB( 255,128,128 )
        END IF
 
        ColorSpec.lStructSize  = LEN(ColorSpec)
        ColorSpec.hwndOwner    = ghList
        ColorSpec.lpCustColors = VARPTR(cColor(0))
        ColorSpec.rgbResult    = initClr
        ColorSpec.Flags        = ColorSpec.Flags OR %CC_RGBINIT
 
        lResult = ChooseColor(ColorSpec)
 
        IF lResult = 0 THEN 'check if user cancelled dialog ?
           EXIT SUB
        ELSE
 
            clrStr = HEX$(ColorSpec.rgbResult,6)
 
            'Use Fomrat here, STR$ adds a leading space I don't want
            rv$ = FORMAT$(VAL("&H"+MID$(clrStr, 1,2)),",")
            gv$ = FORMAT$(VAL("&H"+MID$(clrStr, 3,2)),",") + ","
            bv$ = FORMAT$(VAL("&H"+MID$(clrStr, 5,2)),",") + ","
 
            'Note order of RGB, COLORREF 0x00bbggrr
            clrStr = "RGB("+bv$+gv$+rv$+")"
            pItem(curSel).curValue = clrStr

HTH

Jules

**Jules Marchildon** · 11 May 2001, 03:27 PM

Hmmm...

Scott, You must have been reading my crystal ball while I was typing.

Regarding setting the default color before calling Choose Color dialog, see code
fragment above, it has that too.

Regards,
Jules

Thanks, this is becoming more clear (not so muddy)...

However, Open any web page and look at a color, ie #000080 and lets say that color is the one I am sending to the function...

How do I convert THAT format (String, may or may not have zero's in it) to the RGB long??

It's a formatting issue at this point, but I'm confused and it's friday and I want to go home hehe...

The Color picker actually SHOWS the value too, so I know that HTML colors are the color pickers colors in those boxes...

The blue there is 0,0,128

So far so good....

**Scott Turchin** · 11 May 2001, 04:08 PM

Got it, Thanks Jules...
I modified it shortly, easier way to do it:

Code:

'------------------------------------------------------------------------------------------
Function GetColorSelection(hWnd As Long,ByVal CurrentColor As String) As String
Local ColorValue    As Long
Local sTmp          As String
Local RGBRed        As Long
Local RGBGreen      As Long
Local RGBBlue       As Long
Local RGBColor      As Long
Local lLoop         As Long
CurrentColor = Remove$(CurrentColor,"#")
For lLoop = 6 To 1 Step -1
    sTmp = sTmp & Mid$(CurrentColor,lLoop,1)
Next
ColorValue = SelectColor(hWnd,Val("&h" & sTmp))
If IsFalse ColorValue Then
    Function = "#" & CurrentColor
Else
    RGBRed = ColorValue And &HFF
    RGBGreen = ((ColorValue And &H100FF00) / &H100)
    RGBBlue = (ColorValue And &HFF0000) / &H10000
    Function = "#" & Right$("0" & Hex$(RGBRed),2) & Right$("0" & Hex$(RGBGreen),2) & Right$("0" & Hex$(RGBBlue),2)
End If
End Function
'-----------------------------------------------------------------------------------------

Function SelectColor(ByVal hParent As Long, ByVal iStartColor As Long) As Long
  Local cca As ChooseColorApi
  Dim ccTemp(16) As Static Dword
  Local sTmp As String
  Local InitClr As Long

  cca.hinstance    = 0
  cca.lStructSize  = SizeOf(cca)
  cca.lpCustColors = VarPtr(ccTemp(0))  '<-- !!
  cca.Flags        = %CC_RGBINIT Or %CC_FULLOPEN Or %CC_ANYCOLOR
  cca.hwndowner    = hParent
  cca.rgbResult    = iStartColor

  If ChooseColor(cca) Then Function = cca.rgbResult

End Function
