Read/Write INI File

[Rico Salfer]

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

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 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.

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.

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

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)
els
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)
els
AfxMessageBox(_T("Text not Written"),IDOK,NULL)

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

els
AfxMessageBox(_T("Unable to Open File"),IDOK,NULL)

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