From: Jozo on 24 Feb 2010 07:34 Hi all ! I use very oft SetSelective like: SELF:SetSelectiveRelation(oWindow_DETAIL, #cFld) .or. SELF:SetSelectiveRelation(oWindow_DETAIL,'cFld') and I know that next expressions are correct and works: SELF:SetSelectiveRelation(oWindow_DETAIL," 'M' + cFld ") or SELF:SetSelectiveRelation(oWindow_DETAIL,' "M" + cFld ') but when I write it in the WED, VO changes it in : SELF:SetSelectiveRelation(oWindow_DETAIL,' 'M' + cFld ') and, normally, signals error. Does anybody can to help me, how to write this expression in the editor without error: Relation string = " 'M' + cFld " Thanks in advance Jozo

From: Geoff Schaller on 24 Feb 2010 16:27 Jozo, You need to read the Help because you have this all wrong. The Help is quite detailed and explains the three methods possible: String Code block Array But in the end (and you should review the SDK on this) they are all compiled to a code block so if you provide a string then you MUST provide one that can be compiled into a code block. If you have multi field relations then the simplest option is the array of symbols. Remember the RDD is the one executing the code block so it must have scope that allows this. So to answer your question, you cannot expect complex expressions to be possible using the WED - it can only do things in terms of fields expected. You are better handling such things in a method cal on the class.

From: Jozo on 24 Feb 2010 16:38 Farid, thanks to reply but SetSelective in this example doesn't work although compiler doesn't signalize error. I put this example into PostInit() and works: SELF:SetSelectiveRelation(oWindow_DETAIL,"'M'+cFld") but it made me nervous because I can't it put in editor in Relation string: Editor my expression "'M'+cFld" changes in ''M'+cFld'. I have disjoined characters in this expression that you can perceive what editor has changed Editor this expression " 'M' + cFld " changes into ' 'M' + cFld ' what is not correct syntax and compiler signalizes error Jozo "Farid" <faridwatson(a)gmail.com> wrote in message news:380caf4f-478c-4225-93c8-57f6669b5790(a)t34g2000prm.googlegroups.com...

Geoff, > You need to read the Help because you have this all wrong. The Help is > quite detailed and explains the three methods possible: Although help explains this: <cRelationBlock> When the relation is specified as a code block, a string version of the code block can be provided as well; it is returned by the Relation() method. it has only 3 examples: oDBCustomer:SetSelectiveRelation(oDBOrders, {||_FIELD->CustNo},"CustNo") oDBCustomer:SetSelectiveRelation(oDBOrders, #CustNo) oDBCustomer:SetSelectiveRelation(oDBOrders, {#LastName,#Initial,#FirstName}) Unfortunately, I like use <cRelationBlock> and I have tested my examples like: 'cFld1' (works) 'cFld1+cFld2' (works) 'cFld1+Left(cFld,10)' (works) So, I like use <cRelationBlock> for complex expressions because I "fight" with code blocks although I don't know what is more complex. For example the expression 'cFld1+Left(cFld,10)' is complex for me and passes away in editor but the expression " 'M' + cFld " is not more complex and doesn't pass away. > So to answer your question, you cannot expect complex expressions to be > possible using the WED - it can only do things in terms of fields > expected. You are better handling such things in a method cal on the What I can ! I like expect everything, especially a lot of examples, because the utilization of software depends about it Regards, Jozo "Geoff Schaller" <geoffx(a)softxwareobjectives.com.au> wrote in message news:eRghn.9616$pv.7428(a)news-server.bigpond.net.au... > Jozo, > > You need to read the Help because you have this all wrong.
