I think GetPrivateProfileString is used with IniRead and if we can mod the call to allow for a null Section parameter or a null Key parameter, then the call would return all section names or key names, respectively, from an INI file.

Reference:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getprivateprofilestring.asp

"lpAppName
[in] The name of the section containing the key name. If this parameter is NULL, the GetPrivateProfileString function copies all section names in the file to the supplied buffer.
lpKeyName
[in] The name of the key whose associated string is to be retrieved. If this parameter is NULL, all key names in the section specified by the lpAppName parameter are copied to the buffer specified by the lpReturnedString parameter.".


Chris, can we get this implemented?

I already know about IniKeyGet, but this could be a better option in some cases...

IniKeyGet? What is it? Even Google returned nothing on this word.

BTW, I spotted a typo in the IniRead page: Key | The key name in the in the .ini file.
(stupid BBCode that doesn't allow nesting of color tags...)

I don't know if INI files are so much used, nowadays, that such functionnality is to be implemented. If so, I suppose it could be made on the model of Loop (registry). Otherwise, perhaps a DllCall solution is to be implemented.

I'll add this to the to-do list; thanks. If you need it right away, hopefully it can be done with DllCall.

I have the basic DllCall created and it works:
VarSetCapacity( buff, 10000 )
i:=10000
numchar:=DllCall("kernel32.dll\GetPrivateProfileString",Str,"Section",Str,"Key",Str,"Default",Str,buff,Int,i,Str,"C:\autokey\scripts\test.ini",Int)
msgbox, % buff

Now the issue is with my suggestion of retrieving all the section or key names. I can get it to work, and the buffer contains all key names, but they are nul char delimited. Any suggestions how I can split the buffer using a nul character as the delimiter?

Note that if you want to pass a section or key param as NULL with this call, use Int,0.

Ok, got it working. I had to convert the binary string to hex, change the nuls to newlines and convert the hex string back to binary. I utilized the Bin2Hex and Hex2Bin functions written by Laszlo (thanks!) with a one line modification of Bin2Hex.

Here is my code:

[Laszlo]

Try CharReplace(buff,0,13,numchars) with this function

[Atomhrt]

I tried it with CharReplace(buff,0,13,numchars) and it seemed to choke when it got to the first nul character in the string. In other words, it returned the first key name and then a garbage char, then nothing... Does it work for you? If so, please post INI and example code. Thx

Sorry, the 1st parameter has to be "buff", of course, as you noticed. It works for me (Win XP, SP2, AHK 1.0.43.04):

[Atomhrt]

This is what I was using: msgbox,% "Key Names: " . buff
...which does not work...
msgbox,Key Names: %buff%
... works fine...
Do we have a bug here?

Add "StringReplace buff, buff, `n, `r`n, All". It looks like in expressions `n is not enough for a new line.

[Laszlo]

You can use the CharChange function below, which is slower, but can replace a char with an arbitrary string.

[corrupt]

Using the function I posted above:

[Laszlo]

@corrupt: Your specialized version of StringReplace suffers from the same problem: if you set the delimiter character code to 13 (`n), it won't always be recognized as new line. With your default pipe "|" the problem remains hidden, everything is in one line. If some of your key names contain pipe characters, you are out of luck. `n is safer, because it cannot be part of a key name or value.
