WritePrivateProfileString

[JasonLpz]

Im trying to make a ini file by using the below code but i get this error:

[B]E:\Program Files\Microsoft Visual Studio\MyProjects\ini\main.cpp(11) : error C2065: 'WritePrivateProfileString' : undeclared identifier[/B]

#include <iostream>
#include <stdio.h>
 
 
using namespace std;
 
int main(int nArgs, char** vArgs)
{
cout << "Making C:\\test.ini \n";
 
WritePrivateProfileString ("Section","Keyname","Value","C:\\test.ini");
 
return 0;
}

WritePrivateProfileString is an API function. You forgot to include <windows.h>

By the way, INI files are depreciated. Use registry instead.

[CornedBee]

deprecated, not depreciated , as parksie just explained to someone.

Anyway, I'd prefer some small app to write to a private ini file instead of cluttering up the registry.

[JasonLpz]

i like the ini files because i input alot to the ini file and like CornedBee said i dont want to fill up the registry. Also a single ini file can be erased with a simple

kill "c:\\test.ini";

as with a registry you have to delete the entire folder or every string in it.

[JasonLpz]

also is there a way to get the exe filename ? Like the path?
in vb its App.Path

[parksie]

GetModuleFileName, and use the module handle for yourself that you were given in WinMain.

[JasonLpz]

but how would i do this in a console then

do i just leave the module NULL?

[parksie]

Oh. In a console, it's argument 0, i.e. argv[0].

That gives the name it was *called* as, I believe.

[JasonLpz]

i was trying to do this

LPTSTR vPath ;
GetModuleFileName(NULL,vPath,255);
 
cout << vPath;

but it dont work

[JasonLpz]

that didnt make much sense can you clear that up

[parksie]

An LPTSTR is just a pointer. You'd need to have TCHAR[255]; defined for it to work. I meant:

int main(int argc, char **argv) {
    cout << "Called as: " << argv[0] << endl;
}

[JasonLpz]

ok cool i used

cout << " Called As :\n" << vArgs[0] << "\n";

to get the full path and name like "C:\INI\Ini.exe".
Now how can i cut that up to get just "C:\INI" or "C:\INI\"

[parksie]

In Visual C++, there's the non-portable _tsplitpath function

[JasonLpz]

and i would include
<stdlib.h> right?

[parksie]

Include whatever header MSDN says to include.

[JasonLpz]

ok i got it like:

char drive[_MAX_DRIVE];
   char dir[_MAX_DIR];
   char fname[_MAX_FNAME];
   char ext[_MAX_EXT];
 
_splitpath( vArgs[0], drive, dir, fname, ext );
 cout <<"\n\n";
 cout << drive <<  dir ;

Thanks Alot you and CornedBee helped alot. You guys should get like a new moderator status.

[CornedBee]

We're the mods at Galahtech. That's enough for me.

[JasonLpz]

thank you parksie and CornedBee so much you're teaching me so much and i just wanted to post something i made with all the info you game me. mi going to of course incorparate this into a bigger program. I just posted this to show that you guys do help alot and i commented the code hopefully the right way so anyone can learn also . Thanks once again.
