“Nice” application names
The examples in Samples2 give a good way to put together a list of the currently running applications. Unfortunately, Windows tends to use cryptic names like MSIMN.exe, though.

Is there any good way of getting a human-readable name for each one? The best I have been able to figure out is to check the registry key

I have no idea what the part of the registry is supposed to do, but it usually (but not always) gives a readable application name. (This is with Windows XP Home SP1.)

Just in case you’re curious, here’s the macro I’m using this with. Beware that this probably has a memory bug hidden in it — I don’t recommend it for general use.

(It’s meant to be triggered by a mouse click in the upper right corner of the screen, using a filter function. Filter functions are definitely keen. Smile )

Function GetFileVersionString extracts file description directly from exe. I tested it only with several programs, XP.

Copy      Help
function# $file str&string [$infokind]

;Extracts string from version resource of exe or dll.
;infokind can be one of following strings (default is "FileDescription"):
;Comments InternalName ProductName CompanyName LegalCopyright ProductVersion FileDescription LegalTrademarks PrivateBuild FileVersion OriginalFilename SpecialBuild
;Returns 1 on success, 0 on failure.

;str s
;if(GetFileVersionString("iexplore.exe" &s)) out s

dll# version GetFileVersionInfoSize $lptstrFilename *lpdwHandle
dll# version GetFileVersionInfo $lptstrFilename dwHandle dwLen !*lpData
dll# version VerQueryValue !*pBlock $lpSubBlock !**lplpBuffer *puLen

if(!infokind or !infokind[0]) infokind="FileDescription"

str file2.searchpath(file); if(!file2.len) end "file not found"
int i vis=GetFileVersionInfoSize(file2, &i); if(!vis) ret
str s.all(vis 2) ss; word* lc; lpstr ls
if(!GetFileVersionInfo(file2, i, vis, s)) ret
if(!VerQueryValue(s, "\VarFileInfo\Translation", &lc, &i) or !lc or !i) ret

ss.format("\StringFileInfo\%04x%04x\%s" lc[0] lc[1] infokind)
if(VerQueryValue(s, ss, &ls, &i)) goto return
;lc[0] has problems with some programs (Word, Excel)
ss.format("\StringFileInfo\0409%04x\%s" lc[1] infokind)
if(VerQueryValue(s, ss, &ls, &i)) goto return
ret 1
Thanks! Yes, that’s working reasonably well. A quick note for other people who use the routine — the goto label line
only worked after it was changed to
“ return”
(Note the space before the word.)

So there are now four levels of the script’s logic to find the name.
- Try the mystery registry entry
- Try GetFileVersionString
- If the application has a single visible window, use its name
- Just use the executable name

This works wonderful, but must the entire path be included? I just tried using a different exe file and it didnt find it.

If only filename is used, this will find only files that are in Windows, System, QM, My QM folders, folders specified in PATH environment variable, and folders specified in registry App Paths key.
