Visual Studio 2005 / Framework 2.0 / Leadtools 14.5 / Budweiser Lite 1.0

I'm trying to get the Badcode component to work with the RasterImageViewer

leadRasterImageViewer = New RasterImageViewer

With LEADBarCode

.UnlockSupport(LEADLib.SupportLockConstants.L_SUPPORT_BARCODES_1D, LeadSupport.Support.Barcodes1dKey)

.Bitmap = RasterImageConverter.ToLeadBitmap(leadRasterImageViewer.Image, "LTR14N.DLL")

.EnableGetSizeMethod = False

.Linear.EnableWriteText = True

.Linear.EnableErrorCheck = True

.EnableUseColors = False

.EnableTransparent = False

.Units = LTBARLib.tagBARCODE_UNITS.BARCODE_INCHES

nRet = LEADBarCode.Write(LTBARLib.tagBARCODE_1D_TYPES.BARCODE_1D_CODE_128, "012345678901", 0, 0, 2, 1)

 

.Bitmap = 0

End With

I get no error but (nret=0) but the barcode does not appear, How do you force repaint with a RasterImageViewer ? Refresh sufficiente?

also I was unable to turn off the nag message. I copied the nonag to the system directory. But it keeps appearing.

 

Thanks

The ToLeadBitmap method allocates new memory and stores the converted
image in it.  Therefore, any updates you make to the returned bitmap will not be reflected in the original IRasterImage.

After the call to LEADBarCode.Write, try calling FromLeadBitmap to convert LEADBarCode.Bitmap (which should contain the bitmap with the barcode by now) back to an IRasterImage.

Note that you will need to free the data returned by ToLeadBitmap.
