Spell check with PB 9.1

[Gary Beene]

A second question, please?

How does the version of MSWord a user has on their system affect how your code will perform?

In general, will it work with revisions other than the one I have on my PC? I might guess the answer is Yes, assuming that the word search interface of MSWord hasn't changed much in recent years.

But, since I don't really know what the COM Browser does to create the include file, I won't be surprised either way.

Peter,

I've only just started looking at the COM Browser. Can you tell me which registered library you used to create libword1.inc?

Here is a test code for PB 9.1 (libWord1.inc was created by the PB COM Browser)

I tried using the oWord.inc that was in the Samples directory but it gives me a duplicate definition error. So I'd like to create the same include as you used.

>What is wrong with my first PB code?

Just off the top of my head, I think your problem is trying to use the "direct" syntax with the IDBIND (DISPATCH) interface.

Then again, "crash" has many meanings.... depending on context.

You can't mean a compile-time error, because you would have said so and included the error message.

You can't mean an unexpected runtime error, since your code is not trapping either ERR or OBJRESULT.

You can't mean a protection fault, since you would have said "GPF" and provided the error code.

Darned, I'm out of ideas for what "crash" means in this context. You've stumped me.

I am trying to convert my previous code that worked with PB 7.0 (http://www.powerbasic.com/support/pb...light=spelling) to PB 9.1 using MSWord.

Here is a test code for PB 9.1 (libWord1.inc was created by the PB COM Browser)

#COMPILE EXE
#DIM ALL
#INCLUDE "libWord1.inc"

FUNCTION PBMAIN () AS LONG
     LOCAL oWordApp    AS Int__Application
     LOCAL oSpellingSuggestions AS Int_SpellingSuggestions
     LOCAL oSpellingSuggestion AS Int_SpellingSuggestion
     LOCAL i AS LONG
     LOCAL vSpellingSuggestion AS VARIANT
     LOCAL oDocuments AS Int_Documents

     oWordApp =  NEWCOM $PROGID_Word_Application
     IF ISTRUE ISOBJECT(oWordApp) THEN
         oWordApp.Documents.Add
         oDocuments = oWordApp.Documents
         'msgbox format$(oDocuments.Count)  'returns 1
         oSpellingSuggestion = oWordApp.GetSpellingSuggestions("Helo")  'crashes here when you leave the function
         IF ISTRUE ISOBJECT(oSpellingSuggestions) THEN
            FOR i = 1 TO  oSpellingSuggestions.Count
                oSpellingSuggestion = oSpellingSuggestions.Item(i - 1)
                MSGBOX oSpellingSuggestion.Name
            NEXT
            oWordApp.Documents.Close
        END IF
        oWordApp.Quit
     END IF               
END FUNCTION

This code is crashing at the line
oSpellingSuggestions = oWordApp.GetSpellingSuggestions("Helo")

The exact same code translated to VB6 works (using early binding). Here is the VB code:

Private Sub Command1_Click()
    Dim oSpellingSuggestions As SpellingSuggestions 'Collection
    Dim oSpellingSuggestion As SpellingSuggestion
    Dim oWord As Application
    
    Set oWord = New Application
    oWord.Documents.Add
    Set oSpellingSuggestions = oWord.GetSpellingSuggestions("helo")
    
    If oSpellingSuggestions.Count Then
        For Each oSpellingSuggestion In oSpellingSuggestions
            Debug.Print oSpellingSuggestion.Name
        Next
    End If
    Set oWord = Nothing
End Sub

I could get it work this way (I just don't like the code):

What is wrong with my first PB code?
