Preface

This is a series of articles that has yielded from experimenting with adding some Drag and Drop features to my already-existing application. Due to the complexity of the task, I split the article in several small documents that may easily fit into various CodeProject's sections.

Introduction

The idea was simple: I have an SDI application with a CFormView containing a however-you-like filled out CListCtrl in report view.

The first tricky thing was to use the doc/view architecture with a document file format containing ASCII-strings. Read about that quck'n'clean approach.

Next, I needed to batch-manipulate the data displayed in this control. "So why not use a kind of drag & drop interface with a modeless dialog box and let the user drag the rows he needs into that dialog..." I thought - and that's how this article starts.

You may download all sample MSVC (6.0) projects at once or you can fetch the code for each of these steps:

I'm looking forward to hearing your comments and improvements.

• Create a modeless dialog box as a child or as a sibling of your view (or dialog) window and display it in a message handler.
• Implement the CListCtrl drag source
• Implement the drop target in the modeless dialog
• Take a cup of coffee
• Rework the code and let's see how to make it better
• Write something for Codeproject
• Get a job (this part is done!)
