Product: Spellex Spelling Checker Engine Windows SDK

This document contains information that may be helpful to Microsoft Access developers in adding Spellex Spelling Checker Engine to their applications.

Several functions in Spellex's Windows API, including SSCE_CheckCtrlDlg and SSCE_CheckBackground, require the window handle of the control being checked. Unfortunately, Microsoft Access does not provide a mechanism that allows you to pass the window handle of a text-containing control to the Spellex DLL.

Instead, you can use the SSCE_CheckBlockDlg function. The following example shows how to call SSCE_CheckBlockDlg from Microsoft Access.

Suppose you have a form called Form1. Form1 contains a multi-line text edit control called Memo1 and a button called SpellBtn. Memo1 is bound to a memo field in some table in your application's database. You want the text contained in Memo1 to be spell-checked when the user clicks on SpellBtn.

Create a new module (or update an existing module), and add a new function called CheckMemo1:

Delcare Function SSCE_CheckBlockDlg Lib "ssce5532.dll" (ByVal parent&, _
ByVal block$, ByVal blkLen&, ByVal blkSz&, ByVal showContext%) As Long
Declare Function SSCE_SetKey(ByVal key&) As Integer Function CheckMemo1 () As Integer
Dim text As String
Dim textLen As Long
Dim newLen As Long ' Replace 12345678 in the call below to your Spellex license key, provided
' with the Spellex Windows SDK
Call SSCE_SetKey(12345678) ' Extract the text from Memo1
text = Forms![Form1]![Memo1]
textLen = Len(text) ' Increase the size of the string used to hold the text by 20% to allow room
' for growth.
' 20% is just an arbitrary increment; you may want to add more space.
text = text + String$(textLen / 5, " ") ' Check the spelling.
newLen = SSCE_CheckBlockDlg(Forms![Form1].Hwnd, text, textLen, _
Len(text), True) ' Replace the text in Memo1. The text will have changed if the user
' corrected misspellings.
If newLen >= 0 Then
Forms![Form1]![Memo1] = Left$(text, newLen)
End If
End Function

Create a macro named CheckMemo1. Add the action RunCode to the macro, and set the Function Name parameter of the RunCode action to CheckMemo1. In Form1, set SpellBtn's OnClick property to CheckMemo1.

To call other functions in Spellex's API, open ssce\sdk\vb\ssce.bas using a text editor such as NotePad. Locate the "Declare" statement for the function you want to call. Copy the declarations you need to the clipboard, and paste them into your module's code where other declarations are placed.
