Using FoxPro to Test Presence of Icon in a Program GroupID: Q104472 2.50 2.50a WINDOWS kbinterop kbprg The information in this article applies to:
To test for the existence of a particular icon within a program group in Program Manager, you can use dynamic data exchange (DDE) with PROGMAN.EXE, as follows: 1. Using DDE, initiate a channel to Program Manager from FoxPro for Windows. 2. Store the contents of the desired group to a memory variable by supplying the description of the program group:
m.chan = DDEINITIATE("progman","progman")
m.grp = DDEREQUEST(m.chan,"main","CF_TEXT")
The m.grp memory variable will now contain a listing of all program
items and their properties.
3. Use <expC1> $ <expC2> to determine if the desired program item exists in the m.grp memory variable. The search is case sensitive;
therefore, use the UPPER() function on both sides of the expression
to ensure accurate results. This comparison will return true (.T.)
if the expression was found.
m.found = UPPER("write.exe") $ UPPER(m.grp)
The value stored in m.found will be the logical result of the search. Additional reference words: VFoxWin 3.00 FoxWin 2.50 2.50a KBCategory: kbinterop kbprg KBSubcategory: FxinteropDde Keywords : FxinteropDde Version : 2.50 2.50a Platform : WINDOWS |
