You will need just add your code for your events. Allows to save your time and to work with the comfort. Create the dialog windows fast and easy! All you need is MS Word. Run MS Word and open resource.rc file. Then open callback.doc file and copy the text of your resource file to this document. Then click on the "CreateCallBack" button. Alternatively you can run "CreateCallBack" macro. Then enter the dialog name in dialog window and the work is done! Just paste your callback function to your Visual C project.
