I'm working on a stock exchange information platform and we are thinking in provide a link between our platform and home-made Excel files. The financial market is still bound to the old DDE server approach, now does it still matter today?
Which are the alternatives to make automatic online data updates on Excel files, OLE DB queries? I ...

I have a c# application that opens up a COM instance of excel and dumps some data from an Access 2000 database via oleDB onto the sheet then releases the excel object, but I get a window after I close the program with the title bar:
DDE Server Error: [applicationName.exe] - Application Error
I think I've narrowed this down to be an i...
On a DDE event my program loads a file in and should pop to the foreground.
I was using
show;
It only seems to be working like then when i have hidden the window.
So i added

Again this worked if it was hidden, closed, minimized or in the icon tray but not if it was open just under another window.
I even tried some ...
In a terminal server session, some standard IPC technologies might not work like in a single user environment, because the required resources are not virtualized.
For example, TCP/IP ports are not virtualized, so applications in different sessions which try to listen on the same port will cause a port conflict.
Which IPC technology wil...
I would like to be able to link some data from a custom application to a cell in Excel.
What tech would you use to do that? I'm primarily a Unix-developer, and don't know win32 technologies in depth. But as far as I understand DDE would be the easiest, even though it is very old tech.
Being able to use it with other office suites such ...
Wondering if anyone has experience and/or sample code for making DDE calls from Java. I've done DDE using win32 calls from the stddde library (DdeInitialize, DdeClientTransaction), and could write a JNI wrapper for this, but I was thinking that it might be nice to do it from JNA
I also have some concerns about the fact that DDE calls n...
Hi, I have problem with handling DDE if I want to show CDialog before creating CFrameWnd. I do it in two ways:
1) create MyApp (CWinApp) which has overriden OnDDECommand. Inside MyApp::InitInstance() I create MainFrame (CFrameWnd). DDE works well, OnDDECommand handles DDE calls.
2) before MainFrame I want to show MyDialog (CDialog), bu...
I'm talking to a DDE server I don't have very much documentation for using the NDde .NET library. I've attached handlers for both the Advise and Disconnected events and am receiving data successfully. I never see a Disconnected event raised nor do I see anything in the response stream that seems to signal that all the data has been ret...
I need to integrate an off-the-shelf Windows application with a Java application. At a few key points, I need the Windows application to send an "event" and some data to the Java application.
The Windows application anticipated this need, and can be configured to "Poke a DDE Item", "Set an OLE Auto-Property" or "Write an OPC Item".

I was under the impression that when you double click a file (or choose 'Open With' from the right click menu), Windows simply calls the application with the filename as the parameter. Something like this:
C:\> App.exe file.abc
However, I just double clicked an .xls file and then checked the PEB of the Excel instance that sprang up. To...

I have a third party tool that can send or receive DDE pokes. I have been using DDE spy to monitor communications between it and a 3rd party DDE server emulator, with a view to replicate this using Powerbuilder. As far as I can tell, this is using warm links. I tried using openchannel, followed by execremote, but the type of call is d...
