    Question Dynamic Data Exchange (DDE) Server in Qt Application

    Hy@everyone,

    I have a problem and after days of seraching i can't find anything good to use.

    My problem:
    I have a Qt-Application (xD) and i wanna have the following behaviour:
    When the user double-click a file in the windows explorer the file open this file in our application. If the user double-Click on another file this file should open i the same instance as the file before.

    I know that the "file to application"-binding is called "file association" and in windows this information is stored into the windows-registry (and i know how to do it). I have take a look at it and find out that all programs (Word, Excel, CATIA, Adobe Reader, etc.) that have my desired behaviour use a DDE (Dynamic Data Exchange)-Server to do this. This is an very old technology but it seems it is the only technology which can do that.
    In a MFC-based Application there is already an DDE-Server included. For Qt i can't find anything (only a client to communicate to an existing DDE-Server).

    Does anyone have a DDE-Server Implementation for an Qt-Application or how can i make such a behaviour for an Qt-Application?

    OS: Windows 7 x86 & x64
    Qt: 4.7.3

    Thanks in advance
    Tonka

    Nice post. I learn something more challenging on different blogs everyday. It will always be stimulating to read content from other writers and practice a little something from their store.
