Lawrence,

You can use the POS function to detect the double quotes as in:

(Assuming the field is in X$)...

IF POS(QUO=X$)<>0 MSGBOX "Invalid quote character in data"

Alternatively you could change them to something else using the SUB function as in:

X$= SUB (X$, QUO, "'")

(That's a single apostrophe inside double quotes)

If you happen to be using the standard Windows ISO character set you might try replacing the quote with something like $A8$ which would generally convert like this:

"Quoted String"   -> ¨Quoted String¨

Part of the problem of migrating WindX to a iOS or Android device has to do with real estate and control compatibility.

iNomads provides a solution that addresses control compatibility but many applications are not well suited to the smaller screen sizes and often require rework.  In many cases its just not practical on a small screen to allow for the number of controls/inputs that most applications want.

As for the specific issues you mentioned, we are looking at addressing both the expense of iNomads and the ease of implementation with PxPlus 2019 with the introduction of an App builder.  These should make it easier to integrate PxPlus applications with your iOS or Android devices.

Lastly, for many clients the simple solution for running on a Smartphone or iOS is to use the free Windows RDP app and connect to a Windows server running the application either locally or via WindX. 

The 20000 can be any port you want, it just has to be open on your server so that the workstation can make an in-bound connection to it.

As for multiple users, the logic used to spawn a process does the following:

• Generates a random key (session ID)
• Write this key to a control file
• Locks a control record on the same control file to assure  only one process is doing starting up/connecting at a time
• Spawns a process on the server to monitor the selected port.  This process will listen for incoming connection on the specified port.
• Spawns a process on the workstation passing it the host address, port and random key
• Waits for the record with the session id to be removed (max 30 seconds)
• Removes lock from control record and exits back to process

When the workstation connects to the host the process, it passes it the random key.  The spawned host process then stop listening for any more connections and removes the key from the control file completing the connection which can then be used to run the viewer or any other program.

The above process means only one port is needed and can be shared between users.

If what you are looking for is to dynamically control the presence of the control, just put the button in your Nomads panel but make it hidden. When you need it simply make it visible. 

If you need to dynamically control its location, change its size/position prior making it visible since Nomads generally doesn't care about button positions.

Another option would be to again create a hidden button whose characteristics are based on a theme.  When you want to create your dynamic button simply copy the border and color properties from the hidden button to the button you are creating.  Something like:

ThemeSettings$=hidden_btn.ctl'border.borderColor.hoverTextColor.hoverBackColor.$
...
btnCd'border.borderColor.hoverTextColor.hoverBackColor.$-ThemeSettings$

This will just copy the attributes from the hidden button to the dynamic button.

There is no built-in method to limit file size or scan for viruses but you can do both of these yourself once the file has been uploaded (which is what mamy sites do at least for anti-virus).

What I would generally do is once the file is uploaded, open it (or read the directory) to get its file length.  If too large erase the file and advise the client.

As for anti-virus, it all depends on what anti-virus tools you want and have purchased.  Most have some form of command line utility you can call to check for viruses,  You would need to check with the anti-virus supplier for details. 

If you want a free option or need this for Linux have a look at ClamAV.

It is important to make sure whatever you chose to use for anti-virus protection gets updated regularly.

Actually we had an issue with the disc system (out of space) which we have fixed and are not back up and running.

Mike,

Have you inquired about switching to SFTP or HTTPS for the transfers?

Everything we have read about FTPS indicates its not the easiest to setup and using an explicit FTP it is somewhat insecure.  Also generally FTPS indicates you are using an implicit connection, whereas FTPES is generally used to refer to secure FTP on explicit connections.

Here are some links on the subject:
https://serverfault.com/questions/10807/what-firewall-ports-do-i-need-to-open-when-using-ftps
https://en.wikipedia.org/wiki/FTPS

Lastly, below is a link to a site that talks about how to get curl to use FTPES which may allow you to construct your own command.  It also advises how to deal with the certificate validation, which appears to basically be to copy our supplied cert file to curl-ca-bundle.crt.

Frankly though I still think your should try to use HTTPS if all you are doing is downloading data is the easiest solution.

Ed, *winqry does not have a line 1875 (any version). 

In fact I cannot find any program in our library that have a line number 1875.
