Variant to Struct without knowing the Struct

hsheldon — Wed, 20 May 2026 02:58:56 GMT

Hi All,
I have some JSON data that I want to pass to a function. However, from within the program I don't know what exact struct type is in the function; I know the JSON will fit into the struct but not the parameter type.

I tried putting the JSON data into a Variant using JsonToDataType. It didn't error out but when I pass the Variant as a parameter to the function with type of Struct, it loads more like a string than a struct.

I figure I could approach this problem one of two ways. I can try to figure out the type of the parameter I'm passing to or I can go with a Variant and hope it would convert to the type it's being passed to. Trying to go down the passing Variant route doesn't seem to be working when passing to a Struct. It doesn't automatically convert it.

Any suggestions?

Code:

{ "name": "John", "details": { "age": 31, "female": false, "male": true }, "ratings": [ 8, 7.5, 8, 5.5 ] } in sParamJson



Variant student

Get ParseString of hoJson sParamJson to bSuccess

If (bSuccess) Begin

    Get JsonToDataType of hoJson to student

End



Get TestFunc student to bSuccess



Locals shows student json instead of struct  in the function { "name": "John", "details": { "age": 31, "female": false, "male": true }, "ratings": [ 8, 7.5, 8, 5.5 ] }

Thank you for any help.

oAuth2 Chilkat Object & JSON

Mark Powers — Tue, 19 May 2026 16:54:00 GMT

Working on getting oAuth2 setup & working sending out e-mails using the Chilkat classes. After working with the Chilkat examples and other resources, I finally was able to send an e-mail successfully. My initial tests were using the Chilkat Mailman & email class, but I couldn't seem to get the right combination to work. I was able to get a token back, but it never seemed to work with the mailman class. Then I found an example using more basic using the Chilkat http & json class where the e-mail was built in json and I was successful in send an e-mail that utilized the oauth2 token. But honestly, this feels like "1 step forward and 2 steps back" not being able to use the mailman & email class, so much easier. For example, adding an attachment (which is mainly what I use this for) doesn't seem to be very straight forward using the json method. This is using Microsoft Graph to do the integration. My question is does anyone use the standard Chilkat Mailman & Email class in combination with Microsoft Graph and send e-mails? If yes, can you share a small piece of code?

Thanks

Upgrading License Count 19.1 and 25.0

Leslie L. Brennan — Sun, 17 May 2026 11:51:14 GMT

I requested an upgraded client license count for our existing 19.1 programs from 35 users to 55 users.

I asked the sales rep if the registration codes will work for both 19.1 and 25.0. She said "It should be backwards compatible to 19.1. If you have any issues, I can request a prior version code."

I'm worried if I put the license codes on and there is an issue, my 19.1 systems will be inaccessible, which is not an option.

Should I just copy the existing DFR file, and if the new registration codes don't work, copy the old DFR file back? Or, would it make sense to get "the prior version code" before attempting?

Sorry if this is such a basic question, but I haven't messed with client registration in years, so I'm a little concerned I may break the system.

Anyone with experience on licensing different versions with the same registration codes?

Thanks,
Leslie

clear cookies after a Post request

MrHalland — Wed, 13 May 2026 07:41:23 GMT

Hi!

We are login on to a service, that gives us a cookie with validation in it "Set-Cookie" JSESSION=....

When we are trying for the second time, we do not get the "Set-Cookie".

I have tried to disable the cache of the http client.

If i do this in postman i get a new Set-Cookie each time.

Can you clear the cookies in someway before a new post?

Get all responseheaders from a cHTTP

MrHalland — Tue, 12 May 2026 14:27:00 GMT

Hi!

Is it possible to get all the headers that is returned with a result in DF 25.0

I am trying to trouble-shoot if and what headers that are sent back from the server.

Minor: 25, dbCheckBox doesnt take a label_textcolor

DaveR — Sun, 10 May 2026 21:14:14 GMT

dbCheckBox doesnt take a label_textcolor

Code:

                        Object Emprec1_Func_cashier is a dbCheckBox

                            Entry_Item Emprec1.Func_cashier

                            Set Label_TextColor to clRed

                            Set Label to "*Cashier (30,129)"

                            Set size to 12 80

                            Set Location to 62 95

                        End_Object

it's within a dbgroup on a dbTabpage if that matters.

At home so untested on other versions

ccjGrid, Force enter in EditMode in a given column

Samuel Pizarro — Fri, 08 May 2026 21:36:42 GMT

Adding rows to a cjGrid , programmatically. after it has been initialized (load with initial data)

The grid has only 1 column editable.

I want the focus to be in that row, and column and the grid enters in editMode, so the user just need to start typing.

I Tried this, but it doesn't work

Code:

    Send RequestFindColumnValue of oCountedGaylordsGrid iCol iGaylord False 0 

    Get MoveToColumnObject (oRMC_CountedGlrd_GaylordID) to bRet

    Send BeginEdit of oCountedGaylordsGrid

the 2 previous methods works just fine.

after the RequestFind, the SelectedRow is the desired one (checked in whatches)
and
the MoveToColumn returns False (the good value, which means the move was not canceled )

but beginEdit has no effect !?

The focus remains in the object that initiates all of this, (a button or another grid ).

What is missing ?

multiple HttpPutJson calls, failes?

MrHalland — Thu, 07 May 2026 12:43:04 GMT

Hi!

I have created a http transfer object, adding all the nessecary headers etc.

Then I have a loop sending a HttpPutJson call for each product.
(Yes I know, i didn't write the end-point api)

It only works for the first record, then I always get error 400.

Can you only send once and then you have to recreate the cHttpJson object and send again.

I do not destry the hoHTTP object that i have created initially

Data Entry View Wizard

Garret Mott — Tue, 05 May 2026 20:30:06 GMT

Hi -

DF25

It nicely applies my subclass, but sets peAnchors of dbforms/forms, etc. to anAnchorLeftRight (or similar) - overwriting my subclass's anNone. I will never, ever make a dbForm or the like expand with the view. Grids yes - 99% anAll.

Is there any way to change this behavior? Sure, I can search & replace - but that's just extra work.

Thanks!

New error, at least to me

Bob Worsley — Sat, 02 May 2026 01:53:36 GMT

DF-19.1 & DF-25
I recently replaced my Windoze 11 box as the hard drive died and have begun to intermittently get "Smart App Control blocked an app that may be unsafe" errors when running some of my own programs. I never saw that error on the old 11 box. It's inconsistent, if I delete the .exe and recompile it the problem goes away at least temporarily.

I can see how to turn SAC as they refer to it off, but do I really want to do that? I Googled it and supposedly a program can be unblocked in properties but none of my DF .exe files have shown as blocked.

Suggestions?

DFErr???

Garret Mott — Fri, 01 May 2026 17:44:48 GMT

Hi -

DF 25 if it matters.

I'm working on an error logging system & am confused (yet again).

I see Flexerrs.dat, but also DFErr001, DFErr002, DFErr003, and DFErr005 in the Usr folder.

All seem to be the same structure (Recnum, Error_Descr, and Note). While many recnums are the same, the Error_Descr are all different.

Are they all used? If so, how? I want to make sure I can get the correct description into my logging table.

TIA

revision of Ivan SChoof's cjgrid button

DaveR — Thu, 30 Apr 2026 16:04:42 GMT

Changed Mike Cooper's version to use the newer Codejock naming, ie: 'Report' become 'Grid'.

Still testing but this might someone save a few minutes.

You'll need the SigCjW_GridControl.pkg package. (aka SigCjW_ReportControl but rename every Report to Grid) - Mine is an old copy as I haven't kept the codejock sub so I'd get the latest.

cCJGridColumnButton.pkg

Is Ivan Schoof�s class still the semi-official cjgrid button?

dbSuggestionForm - New Event request - OnSuggestionItemAdd , or something like that.

Samuel Pizarro — Tue, 28 Apr 2026 17:21:10 GMT

Specially useful when working with smFind modes.

On every record found and that is automatically added by the built-in logic, fires an event with tSuggestion as reference, so we can add additional columns to the list.

Today, if you want multiple columns at the suggestion list, you are basically limited to smCustom mode, and need to handle everything.

For example: inside SuggestionsSQLFullText private logic. In the while loop

Code:

Procedure SuggestionsSQLFullText String sSearch tSuggestion[] ByRef aSuggestions

    ...



            While (bContinue)

                Get_Field_Value iFile iField to sVal

                

                If (Found) Begin // and ((bCase and sVal contains sSearch) or (not(bCase) and Lowercase(sVal) contains sLowSearch))) Begin

                    Move (SerializeRowID(GetRowID(iFile)))  to aSuggestions[iRow].sRowId

                    Move (Trim(sVal))                       to aSuggestions[iRow].aValues[0]

                    Increment iRow

                    

                    Send OnSuggestionItemAdd (&aSuggestions)    // <<<----  New event fired with proper record in buffer. 





                    Move (iRow < iMax) to bContinue

                    

                    Send Request_Read of hoServer GT iFile iIndex

                End

                Else Begin

                    Move False to bContinue

                End

                

            Loop

...

Other private functions used in smFind Mode, should also perform the same...

Same feautre could be added to Web and Column equivalent classes.

Appreciate any effort in trying to understand this request.

Regards
