xbrowse command not working properly -- MR. RAO

[Compuin]

Hello,

I am using the xbrowse command to add columns but it brings me empty the browse. My datasource is defined as follows

Code: Select all  Expand view

cSql:= "SELECT * FROM MXCTAALM"
oTb:= TMSQuery():New( oAp:oMySql, cSql )
 

Code: Select all  Expand view

   @ 0,0 XBROWSE oBrw OF oWnd ;
      DATASOURCE oTb;
      LINES CELL AUTOSORT

   WITH OBJECT oBrw
      :SetMySql( oTb, .F. )    // USAR .F.
      :nHeaderLines :=  1
      :nFreeze      :=  0
      :lHeader      := .T.
      :l2007        := .F.
      :lFooter      := .F.
      :lHScroll     := .T.
      :nStretchCol  := STRETCHCOL_LAST
      :bClrHeader   := {|| { 0, 14671839}}
      :SetColor( nClrText, nClrPane1 )
      :SetFont(oFont)
      :bClrStd := {|| {nClrText, IIF( oBrw:KeyNo() % 2 == 0, nClrPane1, nClrPane2 ) } }
      :bLDblClick := {|| Editar( oBrw, .F. ) }
      :bChange    := {|| MuestraRegis( oBrw, cMsg )}
   END

   oBrw:CreateFromCode()

   oWnd:oClient = oBrw

It is a table of 4 columns which it shows and 6 records which it shows but empty.

How do I resolve this incident?

[nageswaragunupudi]

Code: Select all  Expand view

oTb:= TMSQuery():New( oAp:oMySql, cSql )
 

May I know what is the class TMSQuery? What library are you using? Please explain in detail.
Just like I do not know this class, XBrowse also does not know this class and so it can not help.
XBrowse can identify ADO Recordset, TDolphin, TMySql and FWH own mysql classes. (for mysql)

Please give us more details about the library and the class.

It is an Eagle1 command to bring SQL results.

[nageswaragunupudi]

I do not know the methods of this class. So xbrowse does not know.
Now, let us make this work.
Please let me know:
What are the methods to

1. GoTop (eg: oTb:GoTop() )
2. GoBottom
3. GoTo( nthRecord )
4. Bof()
5. Eof()

How do we access and assign field values?
Is it similar to other classes like
x := oTb:fieldname
oTb:fieldname := x
?

Thanks Mr Rao

Code: Select all  Expand view

1.- GoTop  ------->  oTb:GoTop()
2.- GoBottom ---> oTb:GoBottom()
3.- Bof -----------> oTb:Bof()
4.- Eof -----------> oTb:Eof()

x:= oTb:FieldGet( nCol )

 

Let me know if you have any other concern

[nageswaragunupudi]

Can I also assume that:

1. oTb:RecCount() --> number of rows?
2. oTb:RecNo() --> current row/record number?
3. oTb:GoTo( n ) --> Moves the record pointer to nth row?
4. oTb:Skip( +n or -n ) --> skips the record pointer by n or -n rows?

How did you define columns?

Yes, sir

For column in Browse

Code: Select all  Expand view

      oCol := oBrw:AddCol()
      oCol:nWidth      := 50
      oCol:bEditValue  := { ||oTb:FieldGet( 1 )}
      oCol:cHeader     := "Codigo "
 

[nageswaragunupudi]

Good.
Please try

Code: Select all  Expand view

   @ 0,0 XBROWSE oBrw OF oWnd ;
      LINES CELL AUTOSORT

   WITH OBJECT oBrw
      :SetMySql( oTb, .F. )    // USAR .F.
      // add one two columns
      :CreateFromCode()
 

and let me know please.
I will be glad if you patiently help me to make xbrowse fully compatible with TMSQuery

Do these methods also work as expected?
fieldpos(), fieldname(), fieldlen(),fieldtype(),fielddec()
?

[Compuin]

Good.
Please try

Code: Select all  Expand view

   @ 0,0 XBROWSE oBrw OF oWnd ;
      LINES CELL AUTOSORT

   WITH OBJECT oBrw
      :SetMySql( oTb, .F. )    // USAR .F.
      // add one two columns
      :CreateFromCode()

MR Rao, in this way works Ok

Code: Select all  Expand view

   @ 0,0 XBROWSE oBrw OF oWnd ;
      LINES CELL AUTOSORT
     
   WITH OBJECT oBrw
      :SetMySql( oTb, .F. )    // USAR .F.  
      :nHeaderLines :=  1
      :nFreeze      :=  0
      :lHeader      := .T.
      :l2007        := .F.
      :lFooter      := .F.
      :lHScroll     := .T.
      :nStretchCol  := STRETCHCOL_LAST
      :bClrHeader   := {|| { 0, 14671839}}
      :SetColor( nClrText, nClrPane1 )
      :SetFont(oFont)
      :bClrStd := {|| {nClrText, IIF( oBrw:KeyNo() % 2 == 0, nClrPane1, nClrPane2 ) } }
      :bLDblClick := {|| Editar( oBrw, .F. ) }
      :bChange    := {|| MuestraRegis( oBrw, cMsg )}
   
      oCol := oBrw:AddCol()
      oCol:nWidth      := 50
      oCol:bEditValue  := { ||oTb:FieldGet( 1 )}
      oCol:cHeader     := "Codigo "

      oCol := oBrw:AddCol()
      oCol:nWidth      := 150
      oCol:bEditValue  := { ||oTb:FieldGet( 2 )}
      oCol:cHeader     := "Nombre "
   END
   
   oBrw:CreateFromCode()
 

But not for this one

Code: Select all  Expand view

   @ 0,0 XBROWSE oBrw OF oWnd ;
      COLUMS 1, 2;
      LINES CELL AUTOSORT
     oBrw:SetMySql( oTb, .F. )    // USAR .F.
     oBrw:CreateFromCode()
 

Do these methods also work as expected?
fieldpos(), fieldname(), fieldlen(),fieldtype(),fielddec()
?

Yes, these method work Ok as well

[nageswaragunupudi]

Does oTb:FieldGet( cFieldName ) work?

Are you using FWH2012 ?
If so, try making the following modifications to xbrowse.prg and include in your link script.

Replace line 1297

Code: Select all  Expand view

      elseif ! Empty( ::oMysql ) .AND. ::oMysql:IsKindOf( 'TMYSQLQUERY' )
 

WITH

Code: Select all  Expand view

      elseif ! Empty( ::oMysql ) .AND. ( ::oMysql:IsKindOf( 'TMYSQLQUERY' ) .or. ::oMySql:IsKindOf( 'TMSQUERY' ) )
 

Replace Line: 17327

Code: Select all  Expand view

         if uDataSrc:IsKindOf( 'TMYSQLQUERY' )
 

WITH

Code: Select all  Expand view

         if uDataSrc:IsKindOf( 'TMYSQLQUERY' ) .or. uDataSrc:IsKindOf( 'TMSQUERY' )
 

Now, please try

Code: Select all  Expand view

   @ 0,0 XBROWSE oBrw OF oWnd ;
      DATASOURCE oTb ;
      COLUMS "Codigo", "Nombre" ;
      LINES CELL // AUTOSORT

[nageswaragunupudi]

So the problem is with TMSQeuery's FieldPos() method.
You need to resolve this error with the authors.

To make sure, please directly test

Code: Select all  Expand view

? oTb:FieldPos( "CODIGO" )
 

It is better you check all other methods I mentioned above.

[nageswaragunupudi]

In the meantime try

Code: Select all  Expand view

  @ 0,0 XBROWSE oBrw OF oWnd ;
      DATASOURCE oTb ;
      COLUMS 1,2 ;
      HEADERS "CODIGO", "NOMBRE" ;
      LINES CELL    
      oBrw:CreateFromCode()
 

[Compuin]

In the meantime try

Code: Select all  Expand view

  @ 0,0 XBROWSE oBrw OF oWnd ;
      DATASOURCE oTb ;
      COLUMS 1,2 ;
      HEADERS "CODIGO", "NOMBRE" ;
      LINES CELL    
      oBrw:CreateFromCode()
 

I fixed the problem on FieldPos().

Now I get this

Silly question , for xbrowse class, FieldGet is character or number? Same for FieldName data type??

Thanks again

[nageswaragunupudi]

In the XBrowse.prg, Line no:7371

Code: Select all  Expand view

   DEFAULT oCol:bEditValue := { |x| If( x == nil, ::oMySql:FieldGet( cName ), ::oMySql:FieldPut( nCol, x ) ) }
 

Change this as:

Code: Select all  Expand view

if ::oMySql:IsKindOf( "TMSQUERY" )
   DEFAULT oCol:bEditValue := { |x| If( x == nil, ::oMySql:FieldGet( nCol ), ::oMySql:FieldPut( nCol, x ) ) }
