Hi Curry, It's always fun to read your comments and conclusions that can be somethimes interpreted in Dutch as: "de redding is nabij". So, a solution is near to come!

Re: LC Bug: Copying an Image fails
MS Office copy operations are notoriously problematic. Microsoft maintains their own clipboard format, so that when switching to another product the clipboard must be translated. Other apps may do the same. The translation does not always go to plan.

Sean: > char 1 of rawclipboarddata["CF_BITMAP"] crashes it That's simply standing on principle, which I find admirable! After all, give us a char and we'll likely take ... an image. :) But on the tech side, not surprising; char 1 of (the data). -- Paul: > I would consider this a serious LC bug. Indeed it is! Nor is this limited to rawclipboarddata. Nor is it limited even to MS Word I can trigger the same crash with a copied image from OpenOffice. All it takes is reading either of these: fullClipboardData["windows metafile"] fullClipboardData["windows enhanced metafile"] I'll be filing a bug report (maybe two) this week. -- Paul: > Return an error code or even just empty or something A very prophetic statement; that appears to be the case on Mac. I copy a Word image, LC "paste" is not enabled. Thus, likely image copy/paste trouble is not limited to Windows. (As opposed to the separate hard crash bug.) In which case it should be an even more "relevant" priority. More news on that after I've tested with latest LC. -- Finally, I've heard that the LC Team will be taking a look.

Re: LC Bug: Copying an Image fails
Hey guys. There are a few issues around windows clipboard and images. I ran into them ALOT when i worked on the Toolbox application. I (reported bug also). https://quality.livecode.com/show_bug.cgi?id=21543 This probably won't help. but there were times when I had to figure out which key to read from the rawclipboarddata Put it in an image control and then export it out from there.. thats how i avoided some of the crashes and glitches associated with clipboard and screenshots and windows. If any of that seems useful I can check the codebase for the exact steps.

Re: LC Bug: Copying an Image fails
Curry, even asking it to only return char 1 of rawclipboarddata["CF_BITMAP"] crashes it so any attempt to read that data triggers an exception.

Re: LC Bug: Copying an Image fails
Curry, The issue here is that MS Word controls how that clipboard data is transferred. As an example Open the taskmanager In Word, copy an image into the clipboard In LC message box type lock the clipboard; put the keys of the rawclipboarddata Returns something like: Art::GVML ClipFormat PNG GIF CF_ENHMETAFILE CF_METAFILEPICT CF_BITMAP JFIF Object Descriptor image/svg+xml In LC message box, type lock the clipboard; put the rawclipboarddata["Art::GVML ClipFormat"] LC Locks up Then switch to TaskManager and see that MSWord has sprung into life. At this stage it is trying it's best to transfer that data into LC, but probably can't work out how, so they end up in a loop of errors. If you type into the messagebox: lock the clipboard; put the rawclipboarddata["CF_BITMAP"] or any other CF_, it crashes out of LC altogether. Copy the image from MSWord, paste into MSPaint and immediately copy into the clipboard again. Now in LC MsgBx type: lock the clipboard; put the keys of the rawclipboarddata Returns something like: Embed Source Object Descriptor CF_METAFILEPICT CF_DIB Now: lock the clipboard; put the rawclipboarddata["CF_DIB"] and you get the raw data of the image. You cannot do this directly from MSWord clipboard data. There might be a way to achieve it using a 'do as javascript' and following guides listed here: https://ourcodeworld.com/articles/read/491/how-to-retrieve-images-from-the-clipboard-with-javascript-in-the-browser All the best Sean On Tue, 16 Mar 2021 at 15:40, Curry Kenworthy via use-livecode < use-livecode@lists.runrev.com> wrote: > > LC Bugathon continues > > Recently I ran into this bug, which Trevor already reported: > > "Unable to paste images copied from Microsoft Word on Windows" > https://quality.livecode.com/show_bug.cgi?id=21906 > > Copying an image directly (not inline with text) fails. > The clipboarddata contains nulls, in testing so far. > Just tested on 9.6.2 RC 3. > > Any known script workaround? > > (A user behavior workaround, ie copying inline, is not very acceptable.) > > Best wishes, > > Curry Kenworthy > > Custom Software Development > "Better Methods, Better Results" > LiveCode Training and Consulting > http://livecodeconsulting.com/ > > ___ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your > subscription preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode > ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
LC Bug: Copying an Image fails
LC Bugathon continues Recently I ran into this bug, which Trevor already reported: "Unable to paste images copied from Microsoft Word on Windows" https://quality.livecode.com/show_bug.cgi?id=21906 Copying an image directly (not inline with text) fails. The clipboarddata contains nulls, in testing so far. Just tested on 9.6.2 RC 3. Any known script workaround? (A user behavior workaround, ie copying inline, is not very acceptable.)
