Are any methods available in VBA to read and write INI files? I know I could use;
Open "C:\test.ini" For Input As #1
...and parse the data. Instead I am trying to see what tools are already available.
I know in C# you can do...
using INI;
INIFile ini = new INIFile("C:\test.ini");
Is there an equivalent for VBA?
I am attempting this in MS Access 2003 VBA.
Here are some code snippets that we use, it should help you to get the idea. These routines use the API calls. Two functions are included to read / write a string setting to a specific section in the ini file.
Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long
Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpString As Any, ByVal lpFileName As String) As Long
Public Function IniFileName() As String
IniFileName = "c:\[yourpath here]\settings.ini"
End Function
Private Function ReadIniFileString(ByVal Sect As String, ByVal Keyname As String) As String
Dim Worked As Long
Dim RetStr As String * 128
Dim StrSize As Long
iNoOfCharInIni = 0
sIniString = ""
If Sect = "" Or Keyname = "" Then
MsgBox "Section Or Key To Read Not Specified !!!", vbExclamation, "INI"
Else
sProfileString = ""
RetStr = Space(128)
StrSize = Len(RetStr)
Worked = GetPrivateProfileString(Sect, Keyname, "", RetStr, StrSize, IniFileName)
If Worked Then
iNoOfCharInIni = Worked
sIniString = Left$(RetStr, Worked)
End If
End If
ReadIniFileString = sIniString
End Function
Private Function WriteIniFileString(ByVal Sect As String, ByVal Keyname As String, ByVal Wstr As String) As String
Dim Worked As Long
iNoOfCharInIni = 0
sIniString = ""
If Sect = "" Or Keyname = "" Then
MsgBox "Section Or Key To Write Not Specified !!!", vbExclamation, "INI"
Else
Worked = WritePrivateProfileString(Sect, Keyname, Wstr, IniFileName)
If Worked Then
iNoOfCharInIni = Worked
sIniString = Wstr
End If
WriteIniFileString = sIniString
End If
End Function
It's not pleasant, but you can use the Windows API. Here's a link, and another from MS.
FileSystemObject object with a [TextStream](http://msdn.microsoft.com/en-us/library/314cz14s(VS.85).aspx) is the usually recommended method for reading and writing textfiles in VBA.
Karl Peterson's kpini has just about everything you're likely to need: API declarations, a Cinifile class, stuff like that. I'd start with that and morph it to taste, which shouldn't take long.
