@Alexander Sviridenkov So you have implemented the whole office package into Delphi? I hope it's not only for FMX. 😉

holy cow Alexander

I was playing with TWebBrowser and it turns out that it just renders crap in HDPI mode. A simple winforms app with a webbrowser renders everything correctly. Both exe's are added to FEATURE_BROWSER_EMULATION with 11000 and checked the compatibility mode with https://detectmybrowser.com/ Tested in 10.1/10.2/10.3 I could not find any report about it, maybe I'm doing something wrong. Has anyone else experienced this?

Got it. The key is to register the exe name under "FEATURE_96DPI_PIXEL" in the registry with a dword=1. This makes TWebBrowser render correctly in a DPIAware applicaiton. Thank you @Der schöne Günther for the hint!

Wow @Der schöne Günther, bingo. I've compared the manifests between the winforms and the delphi app and the winforms app has no dpiAware:True in it. So I unchecked it in Delphi and voila, they render the same. Thanks for the tip, but.... Now I have an other question... What should I do now? Looks like I would need it for the VCL app but not for the TWebBrowser!?

maybe your original project's exe name added to the registry to run in hihgher compatibility mode? https://stackoverflow.com/questions/25843845/how-to-have-delphi-twebbrowser-component-running-in-ie9-mode

It's amazing that you can argue with a quotation from your own post. Maybe 400% text zoom would be better.

So what? First time experiences with 4K?

scaling, not the text size

no. use 200% scaling for best result

This makes Greta even more sad.

you are right, it wont. this is all what happens: if (FMaxConnections > 0) and (FAddingActiveModules >= FMaxConnections) then raise EWebBrokerException.CreateRes(@sTooManyActiveConnections); Calculating the max allowed concurrent user depends on many things and there is no exact formula. You could do some stress-test to see how the server works under load. This would also test how your dll and connection pool are performing, are there deadlocks, unexpected behavior, etc...

Well, I'd clone/backup the project and start removing all 3rd party units, including firedac. - did you check the system/application events? - if you kill all the w3wp processes in the taskmanager, will then IIS stop faster?

Ok. - I'll assume then that you are aware that in case of TFDManager.Create(SomeComponent), including placing the component on a datamodule, FDManager will be free'd if SomeComponent is free'd. - I'm sure, that you have tried commenting out the whole OnTerminate, and IIS still stalls on stop. Let me know if you find something. I'm really curious.

Ok. How do you create FDManager (Create(nil)?, not that you free it twice) and where is the var declared?

How can you see that? Hourglass, or the time until the dll is released?

sidenote: in "TWebApplication.Create" there is already a "if IsLibrary then IsMultiThread := True;"

ok -what if you remove the .free? Will it leak memory or does it get freed when IIS unloads the dll? -what if you create your FDManager with "TISAPIApplication(Application)" as owner? It's a TComponent descendant so it will free FDManager.

I'm not sure why do you need a critical session for freeing something? Do you think other threads would still using it? And you just freeing it? Just asking.

It shows the values as octal up to 31 except TAB. Nice.

I have no clue what is this for but 0x8 is octal 10 and 0x9 is TAB which is "\t". We still can't see the most important part of the code, how do you evaluate the "output". Anyway, no matter what it is, this is for sure not the way this should be done. Edit: Also, the output is suspicious. "This code has been working on windows for years." How many years? 20? Was it compiled with an AnsiString Delphi compiler?

why don't you hit 'Break' and look into the call stack?

you have to pass it one by one, like: SELECT * FROM tTableName WHERE Status IN (:ST0,:ST1) thus, you have to build your query with there is no "IN (:ONEPARAM)"

I don't get it, if its a remote server, how comes that there is no REST between the client and the server?
