"as short as possible" is not a usable specification. The shortest possible key is zero characters long. The longer the key, the fewer key collisions. You need to specify the exact length you want your key to be. Also, are you really sure that you want to hex encode the key? With hex encoding you are wasting half the bits by using 8 bits (i.e. an ansichar) to represent a 4 bit value (i.e. a hex digit). A more efficient encoding would be something like Base32 (5 bits per byte) or Base64 (6 bits per byte). I believe Delphi has implementations of both. Search the source (or wait for someone here to write what they are, as I'm sure they will do).

I think I can see the problem: You are referencing the Form1 global variable before it has been assigned a value; Your code is in the constructor (or more precisely: an event handler called from the constructor) and the Form1 value isn't assigned until the constructor returns. Do like this instead: void __fastcall TForm1::FormCreate(TObject *Sender) { ... for(j = 0; j < c; j++) { pLayer[j] = new TBitmapLayer(this->ImageBackground->Layers); pLayer[j]->Bitmap->DrawMode = dmBlend; pLayer[j]->Scaled=true; } ... } or simply: void __fastcall TForm1::FormCreate(TObject *Sender) { ... for(j = 0; j < c; j++) { pLayer[j] = new TBitmapLayer(ImageBackground->Layers); pLayer[j]->Bitmap->DrawMode = dmBlend; pLayer[j]->Scaled=true; } ... } Of course it would be best if you could avoid all those global variables (not Form1 but all the others). I don't know if they were just there for debugging this problem.

On my system (Windows 10) the history only contains data copied after first Win+V. Win+V starts the "Clipboard User Service" (svchost.exe -k ClipboardSvcGroup -p). The service is set to manual start. Maybe it's set to auto start on your system? Anyway, the history is not part of the clipboard system. It's just an application on top of it, no different from one that you could write yourself. Trying to access the clipboard history data when there is no public API is IMO a waste of time when you can just replicate what it does. It's not that hard.

AFAIK there's no such thing in Windows as a clipboard history. Applications, and libraries (.NET, UWP, etc.), that offer a clipboard history does so by monitoring the clipboard and making local copies of the content when stuff is copied onto the clipboard. This is why Windows' own clipboard history (WinKey+V) is always empty when you first invoke it. It needs to run in the background before it can collect data from the clipboard; Windows itself doesn't maintain a history. This is also why it is very limited what data is stored in the clipboard history; The clipboard history application doesn't support a lot of formats (mostly text and bitmaps) and some data is only valid at the time when they were copied and require that the data source is live when the data is pasted. You can use the drop target analyzer application from the Drag and Drop Component Suite to see the impact, in terms of requests made to the data source, of running the Windows clipboard history in the background. The drop source analyzer can be used to examine the difference between data copied directly from the clipboard and data that has been through the clipboard history.

I would just use F8 (Step over) but it shouldn't make a difference. Where do you assign a value to c and where is pLayer (which I assume is a dynamic array) initialized? I think you need to show us some more code so we can make sense of what you are doing - and please use the code block.

Seems reasonable; I'll go ahead with that. Even if it ends up a bit higher I wouldn't see a problem with that (for us anyway) but don't let that influence you 🙂 Thanks. Which is also the only reason we need it. Well, to be perfectly honest, although FUDscreen is annoying, I suppose it does guard against the binaries getting tampered with (e.g. infected) after install. They could have solved that another way though but we all gotta have something to do. Who said you can't survive on cutting each others hair (is that even a saying in English?). You misspelled TBD, if that was what it was supposed to say.

Well, aren't I the lucky one? I've just been tasked with finding a code signing solution for our build pipeline. So far the realistic candidates are: Use Bob's test-server PC in the closet and do it manually (Bob's not too thrilled). Use the certificate providers cloud solution and pay per transaction (not gonna happen). Some clever tool that seems to be designed just for our needs. So do you have any idea about what the price will be on this thing?

I might very well be wrong; I don't know enough about GDPR to say otherwise and I should probably keep my mouth shut about the topic. However, I do have some experience with GDPR having worked at medical device- and a pharmacy POS suppliers, with direct access to client/patient data. Only people who had been given permission to act as an agent of the user/customer were allowed to access user data. My point was not that the screenshot wasn't a GDPR violation but that it wasn't much different from the rest of the bug report. I agree; If the application just gathers data (screenshot or not) and sends it of without user consent to a third-party, which haven't been given permission to act as an agent of the user, then yes, there's definitely potential for a violation. But if the end-user is given opportunity to review the data then I believe it's their problem. With madExcept it's possible to have the user review the bug report data, and the screenshot if there is one, before it is sent. I can't remember if EurekaLog has a similar feature.

...and still not relevant to the OPs request

I don't think they understand what GDPR is about. Sending the screenshot would not be any different from sending a call stack or whatever else is in the bugreport. How the receiver treats the data is where GDPR becomes relevant.

Ah... Me neither 🙂

Don't you have the source?

If you contact a developer I'm sure they can figure out a way to translate this, uniquely identifying number, to a string value of your choice.

You can use the CompilerVersion constant. See system.pas The question really is: Why do you need this information at all? The users doesn't need it and supposedly you yourself know which version you used...

I can't really recommend anything with regard to KVM switches as I haven't used one in ages. But don't buy cables that are longer than what you need 🙂 Make a mockup of the whole setup and then measure the required lengths. Cables that are too long can make a mess of even the best designed system. My own system consists of a desktop PC, a laptop (connected to a docking station via Thunderbolt 4), two monitors and a single wired keyboard and Bluetooth mouse. I mostly just use the docking station for charging the laptop and then use remote desktop to connect to it from my desktop system. Both monitors have multiple inputs so I have them both connected to both the desktop and the docking station and if I want to I can then switch the active input on the monitors between the two systems. The keyboard and mouse I have to switch manually. All in all a bit cumbersome so I rarely do it this way.
