Tscan and XHarbour

[byron.hopp]

As I mentioned on an earlier post I got a copy of TScan which seems to utilize the paid for version of the EzTwain from DosAdi. It seems that most people use the free version. Can someone direct me to the location of the Free software from DosAdi. Are there many versions of TScan out there. Which specific prg do I need, what LIB do I need to link, and which DLL's do I need in the app directory. Thanks in advance. It worked great until the licensed ran out.

You only need of eztw32.dll.

I have downloaded that EzTw32.dll, which version of TScan.prg should I be using. My version utilized a Lib file as well EzTwain3.lib which is linked in with xharbour.
I must have some different version. I would much rather use your way. Can you send me the TScan.prg, are there any methods in my code that you do not recognize (oTwain) ?
Thanks,

Here is my spaghetti code...

Function ScanArDoc( oBrowse,nAr_SeqNo )
Local cFile := DtoS( ArRcv->Dep_Date ) + "_" + DtoS( ArRcv->Doc_Date ) + "_" + AllTrim( ArRcv->Company ) + "_" + AmountInFIle( ArRcv->Amount ) + "_" + PadL( ArRcv->AR_SeqNo,5,"0" ) + ".Bmp"
Local oTwain := nil
Local cFileName := SetUpArDirectories( cFile )
If MsgYesNo( "Load Scanner with document.","Yes to continue...")
CursorWait()
SysRefresh()
oTwain := TScan32():New( cFileName )
oTwain:SetRes( 100 ) // 100 Dpi
oTwain:SetHide( .t. ) // Show UI
oTwain:DigiToFile()
oTwain:End()

ArRcv->(RecLock())
ArRcv->Doc_Name := cFile
ArRcv->(DbCommit())
ArRcv->(DbUnlock())

oBrowse:Refresh()
CursorArrow()
SysRefresh()
Endif
Return nil

EMG,

If I add Tscan.obj to my link script and only have EzTw32.dll the the directory I get the following errors listed below.
Is it possible that I either need a Lib file to link in with the obj, or have the wrong obj (my Tscan.prg is not correct).
Any chance you could send me the correct tscan.prg, I must be finding the incorrect one.

Thanks,

Byron ...

Sorry, I don't use nor have Tscan.obj.

Byron; The linking errors you list seem to suggest that you are not linking twain.lib with your app.


Reinaldo.

[byron.hopp]

Thanks,

Were do I find this twain.lib. What time and date stamp should I be looking for?

Byron ...

[reinaldocrespo]

Use Tlib to export from .dll.
