Labels:text | screenshot | document | font | number OCR: Property Function ConnectMode The ConnectMode property determines the type of connection to establish when initiating a link with o DDE server application, A value of ddeAutomatic (the default) means the link is automatically established when the form containing the TDDEClientConv component is created at run time. For most applications, you want to control when the DDE conversation is established. Sct this property to ddeManual. This setting will estab- lish the DDE conversation only when the component's OpenLink method is called, DDEService This property specifies the DDE server appli- cation to be linked to a DDE client. Typically, DDEService is the file name (and path, if nec- essary) of the DDE server application's moin executable file without the .EXE extension. At design time, you can specify DDEService either by typing the DDE server application name in the object inspector, or by choosing Paste Link in the DDE Info dialog box. DDETopic This property specifies the topic of a DDE conversation. Typically, DDETopic is a filename (and path, if necessary) used by the applica- tion specified in DDEService. See the docu- mentation for ReportSmith for the specific information about specifying a valid DDETopic. To control ReportSmith, you will typically use a topic of "System" or "Command". At design time, you can specify DDETopic by choosing Paste Link in the DDE Info dialog box ServiceApplication The ServiceApplication property specifies the main executable file name (and path, if necessary] of a DDE server application, without the .EXE extension. Typically, this is the same value as the DDEService property. Sometimes, however, DDEService is a value other than the DDE server application's executable file name. In either case, ServiceApplication must be specified for Delphi to run an inactive DDE server to establish a DDE conversation. Make sure you supply a value of ReportSmith if your application is supposed to start ReportSmith. Figure 6: Key TDDEClientConv properties.
