vb6 InkEdit; limit to number of lines/ words/ chars?

I have a 'word list' of @ 16,000 words (1 per line) that opens in an InkEdit box, but only shows the first 6,766 words (54,015 chars.)

Is this the limit of what I can load into this at any one time? Googling this gives me no info specific to VB6 so far.

Thanks

The InkEdit is built on top of the RichEdit control, much as the usual RichTextBox is. So in just the same way available addressable memory is the real limit. I don't have problem stuffing in a lot of words:

Maybe you didn't actually put as much text in there as you thought?

18,480 words according to MS word...

From the performance of the program, I'm fairly certain that not only did it not load up more than the first 6000 ish words into the InkEdit box, it didnt put them all in the array either; probably the same number of words.

Your InkEdit TOM demo works fine on my VB6; can I attach the code and files, and someone can run it to see if they get the same result? srolling down the InkEdit2 box, last word on list is 'домосе' on mine...

Worked just fine for me. Loaded 30,000 lines, which was what the NUMBER_OF_WORDS constant was set at.

I changed it to 60,000 words and it still worked fine. Then I tried 200,000 words and it still worked fine. It took 47 seconds to load the 200,000 words.

Also, I scanned the list, and it's getting deep into the alphabet, lots of Ws and definitely some Ys, so I think it's reading all of the wordlist.txt file.

Yes, Dilettante's code works fine, I've modified it to do what I want, and the limit of @6770 chars disappears. Still don't know why my code does that, but who cares, I'll use my version of Dilettante's instead! If thats ok with Dilettante, of course...

If it helps you go for it. Just call me "Old Freebie," fellow Earthicans.

Cheers Freebs!

SendMessage InkEd.hWnd, EM_EXLIMITTEXT, 0, -1 should do the job.

Could be a good point, since the Text and TextRTF properties probably do use EM_STREAMIN.

It's worth a test, although OP might use plain text (EM_EXLIMITTEXT not applicable), and his 54,015 chars do not correspond with the 'official' 32,767 default limit...

MSDN does seem to contradict itself:

Specifies the maximum amount of text that can be entered. If this parameter is zero, the default maximum is used, which is 64K characters. A COM object counts as a single character.

...

Before EM_EXLIMITTEXT is called, the default limit to the amount of text a user can enter is 32,767 characters.

Perhaps one of these is in error? If the default really is 64K it would fit the symptoms.

Just tested it with an empty RichEd control: 32767 exactly.

I'm not sure what you tested, but I don't run into any limit:

Code:

---

Private Sub Form_Load()
    Const CHAR_COUNT As Long = 150000
    Dim S As String
    Dim I As Long

    S = Space$(CHAR_COUNT)
    '"Chop it up" into numbered lines:
    For I = 1 To Len(S) - 39 Step 40
        Mid$(S, I, 6) = Format$(CStr(I), "@@@@@@")
        Mid$(S, I + 37, 3) = "|" & vbNewLine
    Next
    'Stick an asterisk at the last character:
    Mid$(S, Len(S), 1) = "*"
    RTB.Text = S
End Sub

A plain RichEdit control created via CreateWindowEx, no limittext message. Of course, if you let VB or MFC or whatever do the job, you never know what they do under the hood. If you are curious, set a breakpoint, launch the debugger and check for SendMessage...
