My guess is that you are free'ing the ComponentForm while it is still beeing used.

Shouldn't you be in the Debug configuration settings?

Have you tried to start Windows with the safe option and network options on? If it works from here, than there is most probably some services on the computer that is blocking the connection. Maybe your software will not run from the safe option, then you can use ping or telnet to check if the connection is working.

If it's a dedicated db server, give it a fixed ip address outside the dhcp range, and call it with the ip address. I would not use the dns name if there's not an internal dns server on the network.

If you think it's a name resolution problem, you can try to use the ip address instead.

Port 3050 (if it is installed with default options) has to be open on the server

I don't think you can. I've been following the same method as PeterBelow describes, if not, I'm having the same problems as you.

When it comes to simplity and small footprint, Interbase and Firebird will be a good alternative.

Do you have office installed on your computer? I'm not shure, but I think Quickreport is using some Office libraries to do the conversion.

Have you tried DbGrid.OnKeyUp instead. I expect DBGrid.ColExit will be triggered there.

I had some similar experiences where I couldn't get it to work satisfactorily. We have customers with all sizes of phones and tablets. I ended up writing most of the positioning and sizes of controls in code, only controls that are aligned to client are not set in code.

No, as far as I know, you have to download it to the phone and install it under the Encryption & credentials window. I had this problem with a client, that couldn't acces there webservice with some older handheld terminals, after they got a new DigiCert certificate. If we manually installed the certificate, some of the terminals were working again, but for the oldest version of terminals, it wasn't even possible to install the certificate, as it was not compatible with the Android version. After some research we ended up buying a certificate from GoDaddy, that was compatible with the older Android devices.

Yes, Digicert is a well known provider of certificates, but I would check it anyway. When searching for errors, should work is not good enough, double check everything to make shure that it really works. Some older Android devices does not get there certificates updated, and Digicert has issued some new certificates, that's not working on older devices. You can check the certificates from here: Open your device's Settings app. Tap Security & privacy More security settings Encryption & credentials. Under "Credential storage":

Have you checked if your certificate is under known certificates on your Android device? If it's not, you'll have to install it.

If you have multiple instanses of the server on same computer, you will need to use different ports for each instance. The first instance normally get port 3050 and the next 3051, if you not specifically choose some other ports. Can it be that you have multiple instances running and you connect to the first installed via port 3050?
