Bug in my opinion that 4D shows any error dialog while the error handler is active. This is a huge problem for execution on 4D Server or a web server. And if it happens in front of a user they can just hit abort and you have no way to know about the problem unless they complain about it. John

There is no way to recover, but the 4D dialog can capture the exact error and line number and give the user two options, Abort and Continue? I would be fine with 4D aborting the process and writing the error information to the event log. Showing the dialog on the on the server or web server

If storage space is a primary constraint and object indexing is not needed, you can use a blob to store as UTF-8 text. VARIABLE TO BLOB with object uses UTF-8 text (tested 15.4, not 16). In your example where you basically wanted to store an object array directly, you could stringify the

I don't know anything about Xojo, but from the code you posted all it seems to do is set a value on the server and immediately read it back. There is no way for the browser to have it yet. The browser only sets a local cookie from a HTTP response containing a "Set-Cookie" header. If cookies are

Re: Creating Tables by running a method

Pat, Not in the XML, but you could import the table structure (with trigger properties enabled) and then set the trigger code using METHOD SET CODE. My approach would be to enable all the trigger properties even if there is not an immediate need to have a trigger. I don't think there is any

Re: Creating Tables by running a method

The triggers won't run until you set the trigger properties on the table. I'm not aware there is any way to do that via SQL. You can set the trigger properties if you create the tables via XML and use IMPORT STRUCTURE. John DeSoi, Ph.D. > On Jun 23, 2018, at 11:52 AM, Jody Bevan via 4D_Tech

Re: How do I get the type of a Collection element? (v16r6)

New command, Value type: $type:=Value type($col[0]) And note if you use the new For each loop in version 17, all collection elements must have the same type. John DeSoi, Ph.D. > On Apr 26, 2018, at 10:36 AM, Kirk Brooks via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > If I'm iterating

Re: Object get type no longer returns the Object Array type in v16r6

Yes, I thought this was interesting. A useful change, but no compatibility setting for this - all previous code that used OB Get type will need to be updated for version 16R/17. OB Get type can now return Is Date for dates, but it has a compatibility setting where it can be controlled. Also

Re: Testing for Null is superior to OB is defined

This only applies to dot notation you write directly in the method. If you reference properties with brackets [], you can use any property name string you like. One feature that I think is missing is that you can't access a complex property path using a string. For example. $object:=New

Re: Extra characters

The extra characters are the Byte Order Mark (BOM) - see the documentation. A BOM is useless with UTF-8, but there is no way to prevent 4D from inserting it when using TEXT TO DOCUMENT. I use this method instead: C_TEXT($1;$2) C_BLOB($blob) TEXT TO BLOB($1;$blob;UTF8 text without length)

Re: DELAY PROCESS bug

After this discussion I ran a test server for several weeks before upgrading from 15.4 to 16.3 (Mac 64 bit). No problem running jobs on the server interleaved with DELAY PROCESS. After upgrading the production database to 16.3, a client running this same procedure regularly locks up. It seems

BRING TO FRONT for process windows minimized

Not sure if this is a new problem in version 16 (16.3 64-bit Mac) or just something I never realized. BRING TO FRONT does nothing if the window is minimized in the dock. You need to call SHOW PROCESS first even though PROCESS PROPERTIES indicates the process is visible. Also, windows

Re: DELAY PROCESS bug

Bernd, Are you having this issue with the server, client, or both? I'm just seeing it with 4D Client. My new theory is that during a long delay 4D Server disconnects the client because there is no activity and 4D Server timeout (selector 13 for SET DATABASE PARAMETER) is reached. This may be

Re: Bug or feature?

There are no work-arounds for runtime errors. 4D throws up an error dialog and allows the end user to decide what to do, even if executing on 4D Server or in a web process. See feature request and discussion here: http://forums.4d.com/Post/EN/17994245/1/19128922 John DeSoi, Ph.D. > On Feb

Re: Problems installing built application

You can do this with the default data file. The new model allows you to startup your app and then switch to another database without showing the open database dialog. You can switch to an existing one or create a new one on the fly. John DeSoi, Ph.D. > On Jan 31, 2018, at 1:35 PM, macjimbo

Re: Problem with PDF Creation into Temporary Folder (Follow-up)

It may be worth trying to use something other than Temporary folder. That is a long and strange path. I have had problems using it with AppleScript as well as displaying PDFs in web areas. One alternative is to create something in ~/Library/Caches. For example, Get 4D folder(Current resources

QuickReports v16 64-bit Mac on a form

I have a few legacy reports that I have been keeping alive on quick reports. After upgrading to 4D 16.3, it seems you can still have a quick report on a form, but you can't load it or do anything with it in the form On Load phase. For example, QR BLOB TO REPORT fails in On Load (error -9850

RESOLVE POINTER does not work in preemptive processes

Just spent hours chasing this issue down (16.3). RESOLVE POINTER is marked as preemptive ready, but in a preemptive process the name returned for the process variable is always empty. Example C_TEXT(myTextVar) C_TEXT($varName) C_LONGINT($tableNum;$fieldNum) RESOLVE
