Hi,

I'm programming with eVC++ 4 and have the following problem:

My program should use an INI file to read and write several values. To read/write I will use the functions GetProfileString and WriteProfileString (class CWinApp). But each call of this functions failed.

I use the following code (exactly like MSDN and eVC++ helpfile) :

BOOL CMyApp::InitInstance()
{
free((void*) m_pszProfileName );
m_pszProfileName = _tcsdup(_T("/Temp/COMConn.ini"));

// SetRegistryKey("MyApp");
// LoadStdProfileSettings();
....
}

void CDlgClass::ReadIniFile()
{
CString csValue;

....
AfxGetApp()->WriteProfileString(_T("Connect"), // Section
_T("Name"), // Key
_T("MyConnect") ); // Value to write

csValue = AfxGetApp()->GetProfileString(_T("Connect"), // Section
_T("Name"), // Key
_T("Error") ); // Default

....
}

The ini file /Temp/COMConn.ini exists, but each call of WriteProfileString() returns FALSE and each call of GetProfileString() returns "Error".
Why failed every access ?

Please help me (fast).

Thank You

Rico

I know that Windows CE 3.0 doesn't support ini-file functions
(GetProfileString/WriteProfileString functions reads/writes informations in
registry instead of a file). I don't know for PPC 2003.

CE doesn't support the PrivateProfileString APIs. you'll have to either
find/write your own or use some other mechanism for storing settings.

It doesn't either. If you want INI files, you'll have to write the code to
write/read them yourself. You might look at the source for MFC for this; as
I recall, there's some code there that tries to do it.

Hi,
I got same problem.

Here is my code:

CString strAppIniPath = _T("");
CString strValue = _T("");

BOOL bResult = FALSE;
BOOL bResult1 = FALSE;

theApp.m_pszProfileName = theApp.GetAppIniPath();
strAppIniPath = theApp.GetAppIniPath();

CFile obFile;

if( obFile.Open( strAppIniPath,
CFile::modeCreate|CFile::modeNoTruncate|CFile::modeReadWrite ))
{
AfxMessageBox(_T("File Opened"),IDOK,NULL);

bResult =
theApp.WriteProfileString(_T("General"),_T("FirstName"),
_T("ABC"));

if(bResult)
AfxMessageBox(_T("Text Written"),IDOK,NULL);
else
AfxMessageBox(_T("Text not Written"),IDOK,NULL);

strValue = theApp.GetProfileString(_T("General"),
_T("FIRSTNAME"), NULL);

bResult =
theApp.WriteProfileString(_T("General"),_T("LastName"),
_T("XYZ"));

if(bResult)
AfxMessageBox(_T("Text Written"),IDOK,NULL);
else
AfxMessageBox(_T("Text not Written"),IDOK,NULL);

strValue = theApp.GetProfileString(_T("General"),
_T("FIRSTNAME"), NULL);
}
else
AfxMessageBox(_T("Unable to Open File"),IDOK,NULL);

Whenever I read or write ini file I got "bResult " as false. Please
help me to solve this.
