Hejsa,
Nedestående eks. åbner en fil i det korrekte værtsprogram. Hvis du feks. har et tekstfelt på din formular som indeholder hele stien til en fil (dette kunne sagtens være en .ppt-fil. Hvis du har mod på er alt kode med forklaring posten herunder:
1. Opret et nyt modul og paste nedenstående kode ind, gem modulet on navngiv modulet Shell Execute
'Kode start'

Select Case lRet
Case ERROR_NO_ASSOC:

lRet = (varTaskID <> 0)
Case ERROR_OUT_OF_MEM:
stRet = "Error: Out of Memory/Resources. Couldn't Execute!"
Case ERROR_FILE_NOT_FOUND:
stRet = "Error: File not found. Couldn't Execute!"
Case ERROR_PATH_NOT_FOUND:
stRet = "Error: Path not found. Couldn't Execute!"
Case ERROR_BAD_FORMAT:
stRet = "Error: Bad File Format. Couldn't Execute!"
Case Else:
End Select
End If
ShellExecute = lRet & _
IIf(stRet = "", vbNullString, ", " & stRet)
End Function
2. Ved klik på din formular skal du blot skrive nedenstående kode, hvor Me!Feltnavn skal skiftes ud med dit eget feltnavn:
Call ShellExecute(Me!Feltnavn, WIN_NORMAL)
Nu åbnes din i værtsprogrammet.
