anbangs	Posted - Sep 05 2022 : 04:17:12 I have two questions: 1) When I call the acquire method, sometimes the twain dialog box will run behind. 2) When the twain dialog box pops up, click other app on the taskbar to maximize and then return to my app(clike my appicon on the taskbar). The twain dialog box will run behind, causing the program to fail to respond.Other app must be minimized in order for the twain dialog box to appear my ver is 10.2.0 How to solve the above two problems,thanks! attach/anbangs/20229541659_TwainBehind.zip 38.94 KB

anbangs	Posted - Sep 13 2022 : 02:34:02 the same code doesn't work properly on my side. :( thank you
xequte	Posted - Sep 09 2022 : 05:06:57 Hi The code is merely: ImageEnView1.IO.TwainParams.VisibleDialog := True; ImageEnView1.IO.Acquire; I suspect the issue has been fixed since v10.2.0. Nigel Xequte Software www.imageen.com
anbangs	Posted - Sep 08 2022 : 05:28:59 Hi Your demo is normal. Can you paste the code?
xequte	Posted - Sep 08 2022 : 05:09:29 Hi Please download it from: www.imageen.com/temp/legacyphotoen.zip Click the "New" button on the left of the toolbar, and then "Button1" Nigel Xequte Software www.imageen.com
anbangs	Posted - Sep 07 2022 : 01:08:25 can you upload your demo.exe for testing?
xequte	Posted - Sep 07 2022 : 00:17:31 Hi I'm not seeing that here with 11.3.0 (and cannot see any reason it would be different in 10.2.0). I tested it in an MDI application and called it from an MDI client. There might be something else going on in the application... Nigel Xequte Software www.imageen.com
anbangs	Posted - Sep 06 2022 : 03:44:42 Is it only supported when the form is fsnormal?
anbangs	Posted - Sep 05 2022 : 19:36:05 the scanner is Canon DR-M1060 Follow the steps I described and you will understand the twain demos don't. my demo is MID form
xequte	Posted - Sep 05 2022 : 16:39:43 Hi Do you see this behavior with our Twain demos too? What type of scanner is it? Nigel Xequte Software www.imageen.com
