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

PeterBelow, thank you but my question was how to have a base data module class without a DFM

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.

Deploying SQL Anywhere was SIMPLE!

 

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? 

Do you use as embedded or as a server?

Use FDQuery or FDCommand component instead of a FDTable, to run that script.

You will need to open port 3050 in the firewall on the server.

When I run the program it says 'Connection established'.  The error comes when it tries to retrieve data from the table DAT2.  The error says 'no such table.'

 

That should mean it is Ok with spaces in the path, but AFAIK SQLite is a file based db, not a RDBMS, so just to be 100% safe, I would try to place the db file in a path without spaces.

You have a connection path with spaces, are you shure the db component can handle spaces? Not all do.

I think this shold be dealt with at the OS level with user rights.

What happens if the user open the file explorer, and start browsing folders from there?

If you store the values as a Timestamp field, you can show it in the grid with entrance_time.AsDateTime

IBExpert has a tool to compare the metadata of two databases, and generate a update script with the differences.

Can't you design the badge in a report designer, like Fast Report, and print directly to the printer driver?

When you are defining all the fields in runtime, why not also create the table in runtime?
