I use Native translate mode to Download Image From Source.When the Image had been downloaded I need to delete this image .How can I do?
Which information do I send to the source???
Thank you very much!!!August 23, 2007 at 8:52 am #24071
you mean native transFER mode right?
Do you save the image or do you just transfer it and display it?
once the image has been send, the source doesn’t really have anything to do with the image anymore, so I don’t think there is anything you should/could send to the source.
what source are we talking about? scanner?August 23, 2007 at 9:04 am #24072
Yes I save the image in the Disk.
The sourse is Digital Camera
I want to delete image form Camera.What can I do?August 23, 2007 at 9:13 am #24073
aha ok now I get it;
hmm…I think DAT_FILESYSTEM MSG_DELETE should do the job, but I am not sure because I have never had anything to do with a digi cam.
Just check on it: twain spec 1.9 page A-519 has quite a few functions for dealing with files and foldersAugust 23, 2007 at 9:21 am #24074
I use Version 1.8
I will try it.August 23, 2007 at 9:32 am #24075
When could I use the DAT_FILESYSTEM MSG_DELETE ?in which state?
Because I can’t find the DAT_FILESYSTEM in UserInterface.
The vsersion is 1.8August 23, 2007 at 9:53 am #24076
have you checked if your source supports this capability?August 24, 2007 at 2:26 am #24077
I suprised why the userinterface allow me to delete the picture which I selected,but I can’t delete in my app.August 24, 2007 at 7:10 am #24078
what return and condition code do you get when you try to delete a picture?August 24, 2007 at 9:08 am #24079
I can’t find the information of DAT_FILESYSTEM
There is not this chioce in the DG_Control when I open the source.August 24, 2007 at 9:25 am #24080
can’t you check the return and condition code in your app?August 28, 2007 at 7:32 am #24081
I found that my twain doesn’t support the DATA of DAT_FILESYSTEM.
I need a new version higher than 1.8 but where can I download it?August 28, 2007 at 9:41 am #24082
what do you actually mean with “MY TWAIN”? if you mean the twain driver for your camera -> look at the website of the company that made your camera if you mean your twain.h file is too old-> check http://www.twain.orgAugust 29, 2007 at 2:35 am #24083
I use the version of twain.h is 1.8 but the version of twain_32.dll is 1.7.1,I don’t know which the version is actually?August 29, 2007 at 7:23 am #24084
