first test in 2.8 high priority! All the fields values have the same value:false

[jpmoschi]

good morning for me, forum:
A simple error beginning the test of the 2.8 review. May by, it is a project setting option?

my code say
local lseleant := select()

The error is 'Select()' threw an exception of type 'System.ArgumentException'
Data: {System.Collections.ListDictionaryInternal}
HResult: -2147024809
HelpLink: null
InnerException: null
Message: "El valor no está dentro del intervalo esperado."
ParamName: null
Source: "XSharp.RT"
StackTrace: " at XSharp.RT.Functions._SelectFoxPro(__Usual[] Xs$Args)
at XSharp.RT.Functions.Select(__Usual[] Xs$Args)"
TargetSite: {XSharp.__Usual _SelectFoxPro(XSharp.__Usual[])}
XSharp.RT.Select()
error CS0234: The type or namespace name 'Select' does not exist in the namespace 'XSharp.RT' (are you missing an assembly reference?)

Is it a setting option?
thanks in advance

Juan,
Will look at this asap.
This looks like a bug to me.

ok, it is not important because i can replace Select() with DBGetSelect() without alotof work

but it is really important. The query below execute correctly but all the fields values have the same value:false

if SqlExec(1 , "select m03codoper, m03vigente from m03oper","w03oper")= 1
?Evaluate("m03codoper")
False ( Logic )
Value: FALSE
?Evaluate("m03vigente")
False ( Logic )
Value: FALSE
endif
And in whatch window apparently is correct. It should be clarified that the data types of the fields are M03CODEOPER Char(8) and M03VIGENTE Char(1)

XSharp.RDD.DataSession.Sessions {XSharp.RDD.DataSession[1]} XSharp.RDD.DataSession[]
[0] Global datasession Id: 1 XSharp.RDD.DataSession
CurrentWorkarea DBFVFPSQL (W03OPER) XSharp.RDD.IRdd {XSharp.RDD.DBFVFPSQL}
CurrentWorkareaNO 1 Dword
Id 1 Int
Name "Global datasession" String

Juan Pablo,
The evaluate() function uses the macro compiler to evaluate the expression. The macro compiler does not know if the string that you are passing it is a field, local variable, public variable or private variable. This makes it a relatively expensive operation. And apparently (I did not check this) it also fails to resolve this correctly.

Can you try:

Code: Select all

?Evaluate("w03oper.m03codoper")   // Cursor DOT FieldName
?Evaluate("w03oper->m03codoper")   // Cursor ALIAS operator FieldName

These 2 also use the macro compiler
And what is the result if you code:

Code: Select all

? w03oper.m03codoper

or

Code: Select all

? FieldGetAlias("w03oper", "m03codoper")

or

Code: Select all

? FieldGetSym("m03codoper")

hi Robert . The Evaluate() was only used in inmediate window. The screen capture attached is more clear to show the problem.
i create a new Console App
Then run and watch ...

I know what is happening. The sqlexec return the result but the record pointer is in eof() in the new 2.8. release
