Listbox Freeze column and goto a column ( ADO )

[Rick Lipkin]

To All

I am using ADO to connect to MS SQL tables and have been using the standard FW listbox .. Twbrowse and have had no problems ..

I have one routine that needs to be able to 'freeze' the left column at column 5 and also need to be able to move the horozontal cursor to a specific column... say 10

I have been using Hernan's Twbrowse in my ADS version and it works quite will .. however, it has problems with ADO recordsets plus I have to link in ace32.dll .. which is not desirable for this applications.

I need to be able to do something like this .. oBrow:nFreeze := 5
and ON INIT oBrow:gotocol(10)

Does TxBrowse support non-aliased recordsets ?? and if so .. is it possible to freeze columns as well as move the cursor to a specific column ??

Many Thanks

I figured out how to edit Hernan's Twbrowse 'wbrowse.prg' and delete all the references to the different rdd's and left the standard FW behavior ..

But it would be nice to know if there is another listbox class that would be able to freeze and goto a specific column.

Excuse me:

Would you send to me a small sample using ADO & FW listbox ?

Rick,

>I need to be able to do something like this .. oBrow:nFreeze := 5

TWbrowse has a goRight() method but no nFreeze var.

You can do this with TSBrowse.

oBrow:nFreeze:=5
for i = 1 to nCol
oBrow:goright()
next

You can get TSBrowse on my website.

TXBrowse also has nFreeze and goRight().

Rick:

Thank you so much.

TCBrowse has nFreeze as well.

It is very simple to do with xBrowse

Code: Select all | Expand

@ 0,0 XBROWSE oBrw OF oWnd
oBrw:SetADO( oRecSet )
oBrw:CreateFromCode()
oWnd:oClient      := oBrw
oBrw:nFreeze      := 3
oBrw:nColSel      := 8
ACTIVATE WINDOW oWnd ON INIT ( oBrw:SetFocus() )

[nageswaragunupudi]

Works in Dialogs too :

Code: Select all | Expand

   LOCAL oDlg, oRecSet, oBrw

   oRecSet  := GetRecSet()

   DEFINE DIALOG oDlg SIZE 600,400 PIXEL TITLE 'XBRW ADO IN DLG'
   @ 10,10 XBROWSE oBrw SIZE 280,165 PIXEL OF oDlg

   // pl keep the two lines below till FWH releases their fix
   oBrw:nTop      := 10
   oBrw:nLeft    := 10
   // the above two lines

   oBrw:SetADO( oRecSet )
   oBrw:CreateFromCode()

   oBrw:nFreeze      := 3
   oBrw:nColSel      := 6

   @ 180,250 BUTTON 'Close' SIZE 40,13 PIXEL OF oDlg ACTION oDlg:End()


   ACTIVATE DIALOG oDlg CENTERED
