Saving configuration option data
-
I have configuration dialogbox where the user uses the combo box to select and set the configuration. Now how and where can i save the configuration data. and how to retrive last saved configuration Thanks, KarmU
You can use the windows registry for storing your data. The platform SDK provides a set of functions to access the registry. Search MSDN. Another way is to store the data in a text file. This is very easy using the MFC class CStdioFile. MS

i used the following code but it gives assertion failure why? CStdioFile f; char buf[] = "test string"; f.WriteString( buf );

You need to open the file before writing to it. Do it this way: CStdioFile file; CString lineOfText; file.Open("C:\\exaplepath\\examplefile.xyz", CFile::modeCreate|CFile::modeReadWrite); lineOfText="This is the first line"; lineOfText+="\r\n"; file.Writestring(lineOfText); lineOfText="This is the second line"; lineOfText+="\r\n"; file.Writestring(lineOfText); file.Close(); MS

You can consider using the Registry to save your configuration data. Proceed as under (with MFC): 1. Use functions such as SetRegistryKey, WriteProfileString (for a string), WriteProfileInt (for int), GetProfileString, GetProfileInt, etc., of the application class for setting and accessing values from the Registry. 2. You can consider the Constructor or InitDialog functions wherein the stored values can be retrieved from Registry and displayed in the Configuration dialogbox. 3. Use OnOK (or whatever other button-event-handlers) to save the changed configuation data to registry. 4. Use these stored values appropriately in the code to change your program response. For example, use PreCreateWindow function of the mainframe class to change the position or size of main window using stored configuration data.

Hi, honestly I don't like Bill's registry very much... If I need to store any configuration data this is my preferred way. Regards Achikm Klein
