Hi,

I am using LeadTools Imaging toolkit v17 with VB6.
I need to display all the available Page Sizes (e.g. A3, A4 etc) supported by any perticular Scanner in a combobox.
could you please help me with some example, how can I do that?
As I am new to VB, it would be a great help if I get some code example on this.
Thanks,
Tameshwar Thakur

You need to use the ICAP_SUPPORTEDSIZES (L_ICAP_SUPPORTEDSIZES) twain capability with the QueryCapability method (ILEADRasterTwain).

Code is:
+------+
Dim nRet As Integer
Dim TwainCap As New LEADTwainCapability_U

RasterTwain2.EnableMethodErrors = False
RasterTwain2.EnableTwainEvent = True

TwainCap.CapInfo.ConType = L_TWON_ENUMERATION
TwainCap.CapInfo.Capability = L_ICAP_SUPPORTEDSIZES

nRet = RasterTwain2.QueryCapability2(TwainCap)

Dim n As Integer
For n = 0 To TwainCap.CapEnum.EnumNumOfItems - 1
MsgBox "value " & n & " = " & TwainCap.CapEnum.EnumCapValue(n).LongValue
Next

Set TwainCap = Nothing
+------+

Values are documented in the Twain specification document from the Twain Working Group in the section about ICAP_SUPPORTEDSIZES values.

Thanks,
