Im using measurement studio c++ to create a application. How to save a randomly generated value which display in the CNumberEdit Control to a text file? how to do the coding part?

You can use the CNiFile class to write the value out to a file. For example, create a new Measurement Studio C++ project and follow these steps:

1. Add a CNiNumEdit to the dialog.



2. Add a member variable for the CNiNumEdit called m_numEdit.



3. Add a button to the dialog.



4. Double-click the button to add a message handler for the button's BN_CLICKED message.



5. Add the following code to the button's BN_CLICKED message handler:
   

   
   CNiFile file("C:\\Values.log", CFile::modeCreate | CFile::modeWrite | CFile::typeText);
   file << m_numEdit.Value << endl;
   file.Close();
   

   
   



6. Run the application, edit the CNiNumEdit's value, and click the button. The value should be written to the Values.log
   file as specified in the code above.

Hope this helps.
