Antonio,

Continue to get error UR_SUPER_ADDFIELD(0) EG_ARG 1003 SUBSSYSTEM ADORDD

May be I have a wrong version of UR_SUPER_ADDFIELD

What are the expected parameters of this function?

Also the THREAD STATIC does not compile I have to take THREAD out.

I dont have function hb_ntos, hb_stod

Without "common.ch" HB_SYMBOL_UNUSED does not compile.

[Antonio Linares]

In https://github.com/harbour/core/blob/ma ... rayrdd.prg UR_SUPER_ADDFIELD() is used this way:

Code: Select all

   FOR EACH aFieldStruct IN aStruct
      aField := Array( UR_FI_SIZE )
      aField[ UR_FI_NAME ]    := aFieldStruct[ DBS_NAME ]
      aField[ UR_FI_TYPE ]    := hb_Decode( aFieldStruct[ DBS_TYPE ], "C", HB_FT_STRING, "L", HB_FT_LOGICAL, "M", HB_FT_MEMO, "D", HB_FT_DATE, "N", iif( aFieldStruct[ DBS_DEC ] > 0, HB_FT_DOUBLE, HB_FT_INTEGER ) )
      aField[ UR_FI_TYPEEXT ] := 0
      aField[ UR_FI_LEN ]     := aFieldStruct[ DBS_LEN ]
      aField[ UR_FI_DEC ]     := aFieldStruct[ DBS_DEC ]
      UR_SUPER_ADDFIELD( nWA, aField )

   NEXT

nWA seems to be the workarea number and aField is an array with those values.

[Antonio Linares]

I dont have function hb_ntos, hb_stod

Those functions are from harbour standard libraries.

How do you get this error ?

[AHF]

Antonio,

Im working with FWH October 2008 and xHarbour Sept 2008 .

Is this the reason?

[AHF]

Antonio,

As far as I understand I must send in aField[ UR_FI_TYPE ] with clipper standard field types C N L...

But I still get te same error

[Antonio Linares]

Please post here the code that you are using when you fill aField and call the function

Here it is

Hello Antonio,

If you post a full working sample it would be easier to look into the problem.

I tested ADORDD in the past and it worked nice, but indexes were not supported. Are thet now?.

[AHF]

Hello Lucas,

Im using the rddado.prg and .ch posted by Antonio in previous post.
I've proceed with the changes posted after because I always get an error .

I'm trying to work first with dbf files like this.

RddRegister("ADORDD",1)
RddSetDefault("ADORDD")

sele 0
use "whatever" shared

Browse()

I dont know if indexes work now. There is code for it but I still didnt tryed it.
It depends also on the provider.

[Antonio Linares]

Antonio,

All that we can do here is to double check that we have properly filled aField before calling that function.

I doubt there is an error like this in the Harbour RDD engine, so I guess we are suplying wrong values to aField

If everything is ok, we may need to low level trace the RDD code to find the exact value that generates the error.

[AHF]

Antonio,

I checked with msginfo() and the values in aField passed to UR_SUPER_ADDFIELD( nWA, aField ) are:

nWa = workarea number
aField[ UR_FI_NAME ] := "name of field"
aField[ UR_FI_TYPE ] := one of "C","L","D","N","M"
aField[ UR_FI_TYPEEXT ] := 0
aField[ UR_FI_LEN ] := length of the field as number
aField[ UR_FI_DEC ] := number of decimal places as number

aField array 5 elements

The first element shows:

nWA 20
NAME "NRENCOMEND"
TYPE "C"
LEN 10
DEC 0
TYPEEXT 0

and it generates the error.

In the original RDDADO the values were:

nWa 20
NAME "NRENCOMEND"
TYPE HB_FT_STRING
LEN 10
DEC 0
TYPEEXT 0

Same result.

[Antonio Linares]

Have you compared it with the way it is called from ?

https://github.com/harbour/core/blob/ma ... rayrdd.prg

[AHF]

Antonio,

Yes and I checked with :

msginfo(str(HB_Decode( aField[ DBS_TYPE ], "C", HB_FT_STRING, "L", HB_FT_LOGICAL, "M", HB_FT_MEMO, "D", HB_FT_DATE, "N", IIF( aField[ DBS_DEC ] > 0, HB_FT_DOUBLE, HB_FT_INTEGER ) )))

It returns HB_FT_STRING for "C" for example.

All other elements are straight foward.

The error 1003 its a variable not found.

Can this be due for some other reason?

[Antonio Linares]

Antonio,

I guess you have to supply HB_FT_STRING instead of "C"
