You, sir... 🙂

There is no portable version of Delphi available afaik, however I suppose if you copy all necessary files from a PC where you installed Delphi to an other, it might work. But, you have to read the EULA carefully though; I'm not sure if this kind of deployment is allowed. Why installing it is not an option? In my personal opinion a fresh reinstall is always cleaner, guaranteed to work than attempting to "force it to life".

I tried creating a batch file from within the service. It slept 5 seconds (so I can see the process start) called NET STOP, slept 5 seconds (giving time for the service to stop) and NET START. When I called this batch from within the service I remember seeing the process starting and ending when the service terminated. This is why I never used this method. As it works for others I am sure I did something wrong; unfortunately I don't have the code snipplet to debug now. @Lars Fosdal this looks promising, I'll make a dummy service app to test it 🙂

I had this when I had a bug (memory corruption to be exact) in my logging mechanism. The program tried to log it's issue but crashed beforehand. Also, if you use 32 bit processes and your log file grows above 2 GB that can cause your executable to halt.

Well, I have 2 ideas. 1 - use the HTTP status codes. 200 means all fine, it was inserted. 500 means an error happened, transaction was rolled back, resend is needed from the client. If you can not control the status codes, you can add a "status check API". After a 200 OK for inserting the record, the client can query the inserted IDs for verification. If I understand the question completely, that is. But, I never really worked with stuff like this so take this with a grain of salt. I always liked to control everything, so when it was needed I launched my own webserver via ICS. That way I could set return codes, headers, session cookies, and even send detailed answers in any format whenever I wanted to.

Thank you all for the replies guys but I don't want to hijack OP's topic. The methods here seem to be "hacky" (to crash the service and let Windows to restart it - it's a tricky approach I have to admit, though!) or already tried (creating a batch file to sleep for 5 seconds, and issue the NET TOP/START commands. Issue is, as parent program stops, it stops the child processes and therefore the batch file execution too). I was curious if there is a trick to restart a service from within the service itself without the need of a loader, maintenance service - an other executable in general. As it is not that important for me at the moment I'll just keep my eyes open to see if such method was unearthed already.

It's not related to the topic, but may I ask how you implemented the update mechanism? Without a "loader" (e.g. actual code is in a DLL, service only loads and executes the DLL,) I never managed to achieve this. I never figured out how to restart the service from within the service.

Just two notices. If you will ever use Oracle and RetIDList will contain more than 1000 elements, the code will fail. I don't know if any other RDBMS has this limitation though. How trusted is the file? Taking a string value from somewhere and putting it in a SQL command exposes your application to injection attacks.

Can anyone who has 10.4.2 confirm (or just explain if I misundrestood) but TEdgeBrowser now works without the +200 MB download requirements if Windows has the Chromium-based Edge installed? New TEdgeBrowser Extensions The TEdgeBrowser VCL component introduced in 10.4 (a wrapper around the Windows 10 Chromium-based Edge WebView2 control) has been updated with support for the GA version of Microsoft's WebView2 control and its SDK. Besides better compatibility, the component now offers enhanced support for files cache management and the use of custom WebView2 versions.

Hello, I have a method that hides, rearranges and resizes components based on some conditions runtime. All is working fine, but the question eventually arrived: is is possible to "reset" everything to it's original (design time) state? Instead of creating a list of all changed components (and it's properties) I'm wondering if it's possible to re-read and re-apply the .DFM settings to a number of selected components? A list would be easier, but the DFM streaming seems to be the "professional" way to do it. I guess I'll need a TReader for that but I have absolutelly no idea how that works 🙂

This is interesting. I am also changing the style runtime, when the application starts. However at this stage the frame including the TreeView does not exist yet in my case so I'd say it's irrelevant.

My issue is that I have 5-6 TreeViews in my application in different locations and only one seems to be affected. I don't know what is the difference, this is what I was attempting to debug in the first place. If I know more, I will be able to make a small test case.

I had a guess about it, but since at me it is on a frame... but you are right, let me rephrase it to "moving Items.Clear to the owning component's BeforeDestruction event" to be more inclusive 🙂

10.4.1 and 10.3 for sure, I don't know about the rest. I'll check if moving .Clear in BeforeDestruction of the frame helps. That could be a workaround for most of us.

I already started to experiment with the TReader component, unfortunately OnCreateComponent will only let me to use a different constructor other than the default. If the component is not created in the handler it will be created anyway. This thing is still a mess to me though... how do I specify WHERE the new components will be created...? As it needs a stream I need to get it from the executable - I guess it will be stored as a resource...? I'm only at the beginning. I'll find the answers soon enough. This is actually a really neat idea. As the TReader method will create the components anyway I suppose the memory usage will be close to equal anyway. As a huge bonus, I know how to create a new form instance 🙂 An other good idea. Tags are - unfortunately though - already in use in said project 😞 I'll dig into the TReader a little bit so I'll have a basic understanding of how it works / what it does. It never hurts to know something, you never know when you'll need such a thing. Thank you all for your answers!

I like to compile my components and let Delphi use the existing DCUs in my projects. Having my sources on SSD this not just saves time but prolongs the life of the data store as well. I recently started to experiment with a component suite which was written as a blob, runtime and design time in one, therefore I can not build 64 bit DCUs. I never really thought of creating my own component packages and therefore I have 0 experience with this. Are there any tips, tricks or resources that can help me achieving my goal? At the moment I can't even tell how to distinguish what is considered runtime and what is designtime 🙂

Let's say I have aeSuperDuperUtilities.pas and I compile it to all platforms, all configs. Then I set my library / debug DCU path to the relevant output folders, browsing path to the source. If I make a change in said unit, I recompile it again with all platforms / configs. At the moment I cannot imagine a way how any of the compiled DCUs would get out of sync. Then again, most probably I never worked on as many, as complex projects as you did. Can you please give me a theoretical scenario / direct me to an article so I can learn more about this?

* sigh * Yes. That was EXACTLY the meaning of it.

I did not really make components up until this point - maybe that's why I never faced an issue you are talking about. But if I'm not contributing to a component the practice of "download / update -> rebuild DCUs -> ??? -> profit" always worked for me. It seems being the end user has it's benefits sometimes 🙂

This is exactly what I meant, yes, thank you 🙂

@Anders Melander I don't yet have a real-world project which is using this. I only wanted to be able to generate the 64bit DCUs so when a project will use this component, it won't compile the component from source again. I guess I'll have to move all RegisterComponent calls to the design time package, am I on the right track? I guess it belongs there.

So back to the original topic I went ahead and created the two packages based on the article @dummzeuch shared. I coped everything from the original package to this, changed the platform to Win64 and moved the parts what caused the compilation to fail to the design time package (Only design time editors and registration procedures). It worked 🙂 I was finally able to build 64 bit DCUs but then I realized that my design time package contains only ~4-5 of the 20 components. A quick search showed that there are still at least 40 files with RegisterComponents call in my new runtime package, but it still compiles... is this normal? 🙂

Hello, A while ago I started to patch up the dumb TDBGrid component shipped with Delphi. Added some things, fixed some things and now I face an issue where the bottom-right square where the two scrollbars meet flickers white for a moment in some occasions (using a dark theme). I think I know where the bug is but to be honest at this point I'm thinking on abandoning my creation and using something else what someone made, who knows more about this stuff I do. I am willing to spend the same amount of money on a program I earn from it but I use DBGrid in a free tool... so my budget is kinda... tight 🙂 Worst case scenario I'll patch on my ocean of patches until a new one arises. I'm just curious if anyone is using a decent component (or suite) which I can experiment with? I already tried KControls and JVCL. Thanks!
