xbrowse edit dbcombo

PostPosted: Tue Mar 03, 2015 7:03 am

Hello,
I am trying to get a dbcombo functional in this xbrowse sample by Mr. Nages

The oRec:drvr displays fine ,but without any functional dbcombo.

Don't know if I've chosen the proper form of dbcombo or have the syntax correct.

Any help appreciated.

Bruce

1) Please substitute this
Code: Select all  Expand view
    FIELDS oTruc:TAG  , oTruc:Que_dte, oTruc:Shp_dte, oTruc:org  , oTruc:DrpA ,;
              oTruc:DrpB , oTruc:DrpC  ,  oTruc:Drvr   , oTruc:Qty1 , oTruc:Desc1,;
              oTruc:Qty2  ,  oTruc:Desc2  , oTruc:Trip_num,oTruc:Notes ;            
 

with
Code: Select all  Expand view
    COLUMNS "TAG", "Que_dte", "Shp_dte", "org", "DrpA", "DrpB", "DrpC", "Drvr", "Qty1", "Desc1", ;
        "Qty2", "Desc2", "Trip_num","Notes" ;            
 

and try.

2) Please never use FIELDS clause. Please use COLUMNS clause only always.

Please let me know if you still have problems.

Mr. Nages,

I made the changes as suggested ( fields to columns ), but that hasn't had any effect on the dbcombo displaying properly in the CustEditDlg function.

Mr. Rao,

thank You very much.
Your sample is great and very useful for my new project.

best regards
Uwe :D

Mr. Rao,

adding some logic for practical uses to Your sample :

I explain

There is a CUSTOMER.dbf and PRODUCTS.dbf ( instead of STATE.dbf )
CUSTOMER.dbf includes 4 new fields
PRODUCT
VALUE
QUANTUM
AMOUNT

1.) The user selects a product with the combo
2.) Selecting a product, the price from PRODUCTS is added to column CUSTOMER-VALUE from the combo-selection
3.) The user defines the QUANTUM
4.) The field AMOUNT is calculated VALUE * QUANTUM = AMOUNT
5.) TOTAL of column AMOUNT on FOOTER

that makes it VERY useful and saves a lot of input-time !!!

maybe there is any sample :?: , otherwise I have to carry on testing.

Image

best regards
Uwe :?:

Mr. Nages,

The dbcombo sample code you supplied, compiles and runs fine.
I will implement it in my code and persue.
-------

Using Tdatabase() is new to me and the burning question is, what setup is needed
to use your example in a multiuser environment. ( lShared, lBuffer ? ).
Is there a sample somewhere, I could reference ?

Gratefully,
Bruce S.

TDatabase by default is set for multiuser use and is buffered.
I suggest you do not do anything. Just use it.

You can work directly with RDD too. The above sample code works directly with RDD also.
Why do u want to use TDataBase?

Mr. Nages,

>>>Why do u want to use TDataBase?

Your original posted sample used Tdatabase and I thought I'd try and become familiar with it.

I am relatively new to FWH.
I have converted all(most) of my Clipper programs to FWH and want to make them all into multiuser applications.
I'm familiar with record /file locking the old way, but knew the next step was to take advantage of ADO, ADS, SQL, etc. of which I know nothing about.

Also, using ADO examples in the forum, I have built working applications.

The wrestling with above samples helps me to begin to even ask valid questions.
I'd like to stay with .dbfs and apply something with a decent learning curve.

The vaque question is, which one do I choose ?

Recently, Jeff Barnes and others threads have provided food for thought.


Regards,
Bruce S.
