hrc	Posted - Sep 05 2012 : 03:59:12 On slower machines I experience an error when my scan-form is opened. In the constructor I do an TWainParams.Update which fails. If I continue through the messages and try to scan, it works fine. My own machine doesn't have this problem so I assume some form of scan-component initialisation is done, perhaps threadded. If this is true, how can I stall the form until it's ready? I use the second to newest version of the component package

xequte	Posted - Sep 06 2012 : 15:02:34 Have you confirmed this by delaying TwainParams.Update until after the form is ready, e.g. using FormShow or a postmessage? Nigel Xequte Software www.xequte.com nigel@xequte.com
