[RESOLVED] .ini & SaveBarState problem

[Rabelo]

Hi!

I´m developing an aplication where I save the bar state to a .ini file. Im setting m_pszProfileName = ::_tcsdup(_T(".\\MYAPLICATION.ini")) to avoid using the registry. The problem is that VS is creating the file not alowing to the commum users to write to the file. This way, for the commum user of my aplication the new state of the bars are not being saved. If I run the aplication as administrator the problem does not happen (I cheked the permitions of the file and for commun users writing is not alowed). Is there any command on the MSVC C++ to create this file alowing the commum user to write to the file? My goal is alow the commum user of my aplication to have the bar state saved transparently without need to call my aplication as an administrator.

Thank you

Have a look at this blog: https://blogs.msdn.microsoft.com/pat...e-os-versions/

Thank you for answering.

I´m using Windows 7 and as on that blog I should save the ini file on "%USERPROFILE%\AppData\Roaming\<MyCompany>\<MyApp>" but it is not working. The toolbars state is not being saved. I changed the path to:

m_pszProfileName = ::_tcsdup(_T("%USERPROFILE%\\AppData\\Local\\Company\\Aplication\\Aplication.ini"));

is this correct? The \\ are required and the USERPROFILE as a system variable may be sourronded by %, rigth?

Thank you

Just look at the debugger/output window the string m_pszProfileName points to after ::_tcsdup(...).
Is it what you expected?

It does not change. The "%" simbol remains in the string. I expected that this variable (USERPROFILE) to be expanded to its value. In the tcsdup it is not. I debuged deep in the LoadStdProfileSettings(4) (where the .ini is loaded) and the % remain on the path, so I guess I will need to get the value of this enviroment variable by myself. I´m going to do this and let´s see if will work.

Why not use SHGetKnownFolderPath() to obtain the correct path to "%USERPROFILE%\AppData\Roaming\" for the various OS versions (since Vista) with parameter FOLDERID_RoamingAppData. See https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

Consider example

#include <ShlObj.h>
#include <iostream>
using namespace std;

int main()
{
	PWSTR wnm;
	SHGetKnownFolderPath(FOLDERID_RoamingAppData, 0, NULL, &wnm);

	wcout << wnm << endl;

	CoTaskMemFree(wnm);
}

which on my system displays

C:\Users\admin1\AppData\Roaming

The application specific part can then be appended to this.

PS Why change roaming to local?

I think this is exately what I need. I´ll try it.


Thank you

Ok, it worked. I got the correct path and the .ini file is being saved with all permitions for all kind of users.

Thank you
