But from what I understood DDE support was removed from VB.NET. The Beta 1 release of VB.NET had an incomplete COM wrapper mechanism which prevents DDServer events from working and was supposed to be added later; I'm not sure if it is a completely functional API. But here's are examples of <a target="_new" href="http://www.vsnetfr.com/lien.aspx?ID=5161">DDEListener</a> for C#. <br /> <br /> What you may could do is use some of the older components of VB6 via COM or there may be a third party control that can add DDE support to .NET.http://forums.asp.net/thread/686799.aspxWed, 08 Sep 2004 18:11:16 GMT4c671506-2930-414c-a40b-8bf57ded5924:686799Hondaman9000http://forums.asp.net/thread/686799.aspxhttp://forums.asp.net/commentrss.aspx?SectionID=12&PostID=686799Spotted this topic searching for info on DDE hookups. Any ideas how to link a DDE data feed to a charting control on an ASP.NET/VB.NET aspx? <br />http://forums.asp.net/thread/336978.aspxFri, 12 Sep 2003 12:23:32 GMT4c671506-2930-414c-a40b-8bf57ded5924:336978PD_Goss0http://forums.asp.net/thread/336978.aspxhttp://forums.asp.net/commentrss.aspx?SectionID=12&PostID=336978You can use DDE in VB6, but you may have to use a third party DDE Server to create the link. I wrote an application several years ago that interfaced with PLC's for large pump stations using DDE Server and then moved to DsData. You use the LinkTopic, LinkItem, LinkMode, and LinkTimeOut properties of your controls to access the data. At least in my old app that's how it worked. <br /> <br /> Again, that was several years back and I am not sure if there are better ways to connect to a DDE source these day. I do know that after W2K, MS changed the way DDE is supported in their OS. <br /> <br /> Good luck.http://forums.asp.net/thread/336887.aspxFri, 12 Sep 2003 09:19:15 GMT4c671506-2930-414c-a40b-8bf57ded5924:336887goon_power0http://forums.asp.net/thread/336887.aspxhttp://forums.asp.net/commentrss.aspx?SectionID=12&PostID=336887Thanks in advance!
