returned ini values have ||||||| at end

I am pulling info from a .ini file and the value in a variable looks like this:
VALUE||||||||||||||

What are those | things and can I just do a replace | with nothing?

Thanks.

Trim it

They are junk, and Trim should remove them

Already doing this and not triming it off.

Code:
gsLocation = Trim(Temp)

It's Ascii 124 - a pipe sometimes called 'logical or' symbol

It's on the Keyboard, usually on the \ (backslash) key

Code:

---

mystr = "VALUE||||||"
mystr=Replace(mystr,chr124),"")

---

That's Chr(124)

PS: are you using GetPrivateProfileString or some other api to read the INI file? That works better.

The following doesn't work either:
gsLocation = Replace(Trim(Temp), Chr(124), "")

HERE IS THE WHOLE SECTION OF CODE:
Dim ret As Long
Dim Temp As String * 50
Dim sLoc As String

sLoc = "c:\windows\File.ini"

ret = GetPrivateProfileString("Location", "FullPath", sLoc, Temp, Len(Temp), sLoc)

If ret = 0 Then
Beep
Else
gsLocation = Replace(Trim(Temp), Chr(124), "")
End If
.....

real quick do this

msgbox Right(gsLocation,1)


tell me the messagebox says

I give up. Something else is going on. Replace works just fine when I try it on my machine here.

after setting gsLocation of course

Cander - nothing appears so I am going to say it's a space maybe or could it be null?

a null .
here try this

Code:

---

Do Until Asc(Right(Temp, 1)) <> 0
    Temp = Left(Temp, Len(strName) - 1)
    DoEvents
Loop

gsLocation = Temp

---

oops change strName to Temp

Cander - That didn't work either.

arggh. well im tapped out of ideas

Join the club. He's doing something else somewhere or he's working with hosed data.

Oh. wait. Hosed data - he isn't init - ing the temp string

Code:

---

Dim Temp as String *50
'add
Temp = string(chr(0), 50) ' initilaize it to all chr(0)
....
After you get a RETURN


Temp = left(temp,instr(temp,chr(0)-1)

---

See if that doesn't help

Give me a type mismatch error on this line.

Temp = string(chr(0), 50) ' initilaize it to all chr(0)

Do you need to use a fixed length string?

That is causing all your problems

Yeah, I hear you on that one. I tried without and it doesn't like that for some reason.

Here is where I got info on it:
http://www.vb-world.net/files/tip17.html

I inverted the arguments. If you can code you can fix it, too.

:D

Jeez Louise.

Code:

---

Temp = string(50,vbNull) '  it to all chr(0)

---

This is why you have the trailing crud. GetPRivateProfileString uses null-terminated string because it is written in C

This is what I always use and it works without problems.

VB Code:

   'so you could write a default value here if u wanted
   Call WriteIniFile("MyApp", "DataSource", "C:\Temp", iniFile)

Here is some code I found here at vb-world that works great.

Function TrimNull(sNullString As String) As String
'=========================================================
'=========================================================
Dim iLen As Integer
Dim iTemp As Integer
Dim sTemp As String

iLen = Len(sNullString)
iTemp = InStr(sNullString, Chr$(0))

If iTemp <> 0 Then
sTemp = Left$(sNullString, iTemp - 1)
sNullString = sTemp
End If

TrimNull = sNullString

End Function
