Read and Write in ini file

Question

I create one Ini file, but it is not performing any read write operation on this file.
When I debug that code it shows that value of theApp.m_pszRegistryKey is 0. I used eVC 4.0 which support only WriteProfileString of application object. How to set the registry key? Help me.

Please find the code below

C++

CFile obFile;
BOOL bResult = FALSE;
 
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);
 
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);
}
else
AfxMessageBox(_T("Unable to Open File"),IDOK,NULL);

Without seeing the code that is not working it's impossible to guess what the problem may be. Please edit your question and add some more detailed information.

I got value of pApp->m_pszRegistryKey as zero which return the value of pApp->WriteProfileString() as false. Please debug that code and give me answer.

you can set a key which has stores the applications profile settings via the member variable m_pszRegistryKey.

eg:pApp->m_pszRegistryKey = "MYKEY"also set NULL value after usage
this key will be found under HKEY_CURRENT_USER->SOFTWARE in registry

It's not working. I got bResult as true but no updation is done in the ini file

Resmi Anna 10-Apr-12 9:16am

check using the function GetProfileString() to see whether the value has been updated.

like below

CString csValue = pApp->GetProfileString(_T("General"), _T("FirstName"));

are you not getting the value "ABC" in csValue??
actually these setting details are updated in the registry.not in any INI file. You dont need to bother about viewing those details.just ensure that from program you can access it

Vaibhav_J_Jaiswal 10-Apr-12 9:26am

I got the answer. Using WriteprofileString or GetProfileString we never update the ini file in eVC 4.0. Because these api's read the value only from the registry. For the ini file can I use any other concept. Please suggest further.

you can just make use of the INI file concept. You can have your application settings in the system and read it and write to it just like you do it in an INI file. But actually it is in registry. You dont need to bother about such things. You just want your application to read correct profile settings value..Thats it rt?...Is your issue solved now?

My TL give me another work so I give you reply regarding to this later. Thanks for your help.

I make the registry as you say HKEY_CURRENT_USER\\Software\\MYKEY in WinCE 4.0 and then check, this time also I don't get registry value or updated the registry value same is happened for Ini file. What should I do now?
