C#

Yes, but it would refuse to load the DLL even if there were no code changes or assembly property changes. I think I have solved it however. There is a file in the DLL project named AssemblyInfo.cpp, and it contains an assembly attribute named AssemblyVersionAttribute. And it was set to L"1.0.*". I think this was causing the problem. The asterisk means that it should autoincrement the version number. I changed the value to L"1.0.0" and it no longer fails to load the DLL if the DLL is rebuilt. Thanks for reading my post and for your input! The difficult we do right away... ...the impossible takes slightly longer.

Some file formats allow embedding a thumbnail in metadata. For example JPG allows it in the EXIF data section. Not all image formats support this, and even if they do, not all images will have it. And even if it is present, the quality might not be sufficient. I have not looked at it for years (decade+) so have no code nor libraries, but maybe googling "EXIF thumbnail c#" or similar will help.

Yousef10 @ stackoverflow (SOS: "Microsoft Print PDF" PaperSize) says "don't worry" ... it's the printer's fault. And your code's the same as his; so first step -> try running your print PDF routine with a different printer?

Once again you help me, OriginalGriff. I'll Think about. Thanks.

Actually I think there is a much simpler answer.

Not in a standard combobox - it's a single row item which selects the entire item. What are you trying to achieve that you think you need this: there may be a better way.

At a guess - and I don't play with print queues so that's all it can be - it's that your app needs elevation, or you need specific permissions to access the two print queues involved. "Access denied" means you don't have a required permission, so it's likely to be one or the other. Which makes a lot of sense, since the print queue may contain items from multiple users! The simplest way to check which is to run your app in admin mode and see if the problem goes away. If it does, then that's what you need - an elevated app. If it doesn't, then you need to tell the printer queues "who you are" in order to change them.

The old DataGrid wasn't very flexible. You don't have the control over its rendering like you do with the DataGridView. The only way to SIMPLY get the functionality you want is to drop the DataGrid and replace it with the DataGridView. Otherwise, you're writing a whole bunch of drawing code and drawing the DataGrid yourself. You really don't want to do that.

Good point, Griff! I didn't know that option existed! The difficult we do right away... ...the impossible takes slightly longer.

Trouble is that unless you know something exists, you can't look for it - a course or book presents everything in a structured manner so it's easier to understand, and provides exercises to check your comprehension. It also helps to "cement" the learning - we learn by doing, not by looking - you can watch as much of the Tour de France as you like, it won't teach you to ride a bicycle! :D "I have no idea what I did, but I'm taking full credit for it." - ThisOldTony "Common sense is so rare these days, it should be classified as a super power" - Random T-shirt AntiTwitter: @DalekDave is now a follower!

I found the answer: It's a known issue in Edge version 126. The fix has been included in Stable 126.0.2592.81, which had been released on June 27, 2024. Please install the latest Edge Stable version 126.0.2592.81 (Official build) and test again.
