**DDEAPP( )**

{{blk2blue.jpg|blk2blue.jpg}}

The **DDEAPP** procedure returns a string containing the application name in the DDE channel that has just posted a DDE event. This is usually the same as the first parameter to the DDESERVER or DDECLIENT procedure when the DDE channel is established.

**Return Data Type:     **STRING

**Example:**

**ClientApp STRING(20)**

**WinOne  WINDOW,AT(0,0,160,400)**

**         STRING(@S20),AT(5,5,90,20),USE(ClientApp)**

**        END**

**TimeServer LONG**

**DateServer LONG**

**FormatTime STRING(5)**

**FormatDate STRING(8)**

** CODE**

** OPEN(WinOne)**

** TimeServer = DDESERVER('SomeApp','Time')    !Open as server**

** DateServer = DDESERVER('SomeApp','Date')    !Open as server**
