problem with fw_adoexporttodbf function

[max]

I think there is a bug in FW_AdoExportToDbf function. When it meets a SQL field type "varchar(MAX)", the output dbf is created with a character field (instead of "memo" field) length=0, and without content. To fix this problem, need to declare interactively the structure of dbf at runtime moving ".T." in the third parameter of the function. But in this way the program stops execution asking name and field attributes to the operator, and it is not always possible.
Detected with FWH version 1807 and exporting a table of a MSSQL database.
There is a way to solve? Thank you.

This is taken care of in later versions of FWH.

Try making this modification in \fwh\source\function\adofuncs.prg
Locate the function function FWAdoFieldStruct( oRs, n )
Add these lines towards the end of the function just before "return"

Code: Select all

if cType == "C" .and. nLen <= 0
   cType := "M"
   nLen := 10
endif
 

Please let us know if this works.

Afther this change i have to recompile adofuncs.prg, right? How? Thank you.

[nageswaragunupudi]

After this change, you add the revise adofuncs.prg to your project as one of your prg files.

Linking adofuncs.obj to my project now i receive these errors linking:

Max,

Have you recently modified your bcc7 files ?

Please check that you are using the right bcc7 libraries

[Antonio Linares]

Max,

Please post here your make file or batch file that you use to build your app, thanks

[max]

No Antonio, i have not modify my BCC7 files (far from me! ) . And all other my projects without link to adofuncs.prg are ok with this batch for compile and linking. Perhaps I've been doing something wrong since I added adofuncs(!?). This is the batch i use:

I still have the same unresolved problem today

[nageswaragunupudi]

In case you are using the next version immediately after this post, you need not recompile adofuncs.prg. You can use FWH libraries without any change.

[max]

ok thanks Nages. In other words, I have to buy the updated version today to solve the problem reported here of FW_AdoExportToDbf with SQL field type varchar(max). Is it right?
