How to open more than 6 instances of Microsoft Visual C + +. __c++

Many people can turn on Visual C + + 6.0 abbreviation VC6 and go to work when you double-click a file with a suffix named. dsw. But double-click one. DSW, in the same VC6 inside open, the general solution is to open a VC6, open the work space. However, there is a solution http://topic.csdn.net/u/20070703/14/c5756311-57b8-4360-a118-d686481efa51.html above URLs tell a way to open a folder casually, Then select the tool in the menu-> Folder Options-> File Type-> dsw-> Advanced-> select Open, click Edit Button-> remove "Use DDE" check

Dde

DDE is a dynamic data exchange mechanism that is dynamically exchange,dde. Using DDE communication requires two Windows applications, one for the server to process information, and one for the client to obtain information from the server. The client application sends a message request message to the server application that is currently activated, and the server application responds based on that information to enable data exchange between the two programs. In later versions of LabVIEW6.0, DDE is still available, but NI advocates the use of ActiveX, so the DDE VI does not automatically appear on the function template. If used, it can be found in LabVIEW x.x//vi.lib//platform//dde.llb. DDE (Dynamic data Exchange) works by: Party A applies for a chunk of global memory, then postmessage the memory pointer to party B, and party B accesses the global memory according to the received pointer. There are several API functions that do this, and you check out the Dde functions in MSDN. because it is obsolete technology, even MFC does not encapsulate him. It is difficult to guarantee that it will also appear in future Windows APIs. DDE = Dynamic data exchange, which is a technology that enables the exchange of data and control between different applications in the 16-bit Windows age, and is now used infrequently, and the Windows shell shell opens some file types with DDE. OLE = Object linking and embedding, developed from the 16-bit Windows age, is based on COM (in fact, OLE is the first practical application of COM, and when OLE standards are launched, COM standards are not yet stereotyped; COM 's maturity depends on the technical maturity of OLE, the COM standard recently seen is version 0.9.
