This is the piece of code I had written to write to the config file

wxFileInputStream NamesStream("config.txt");
wxFileConfig *ConfigNames = new wxFileConfig(NamesStream);
bool b = ConfigNames->Write("ramu","[email protected]");

The return value is true but it doesn't write anything to the file.

I don't have any problem reading from the config file. Can somebody tell me whats the problem with Writing to config file.

Thanks for finding that mistake.Does the same file config.txt can be assigned to output stream.

I tried replacing input stream with output stream, but it doesn't seem to work. Can u just provide a code snippet for reading and writing into same config file.

I usually work with std:: o/ifstream for writing/reading files.
So I am not familiar with the wxFile stuff.
Acutally, if I look at the Docs, wxFileConfig::Save could be worth a try.

That was the problem. I was not Saving after writing. Thanks a lot.

Here is the code I use (after been helped on this forum)

Code: Select all

wxFileConfig * file_config = new wxFileConfig(wxEmptyString, wxEmptyString,"My PATH");
file_config->SetPath("/My GROUP NAME");
file_config->Write("My KEY NAME", "String to add");
file_config->Flush();
If this can help you....
