TOPIC:

Hello,

In a project I have several forms that access the database (PostgreSQL) through a data module.
All work fine except 2 which, although in the uses clause they refer to the data module, they do not "see" datasources in there when I try to assign datasource to the data components.
Is there any mistake I made? Is there anything I can do to avoid redoing the forms?

Thanks in advance

Thanks
but we need more info:
-Your OS and CPU
-Your CT version
-Your source sample with the problem
etc

Hello,

but we need more info:
-Your OS and CPU
Me: Windows 10, Intel Core i5 4670
-Your CT version Me: 7.1
-Your source sample with the problem
Me: see the attached file conta.zip



// This is a partial list of files in the project
// compressed in the attached file conta.zip
// The bin directory is important
// The file menu_image.jpg will help you
//
//
contas.ctpr // project
contas.ctps
contas.ico
contas.pas
contas.res
meu_layout.xml

//tree menu (see attached picture file: menu_image.JPG)
u_menu_contas.frm
u_menu_contas.pas


// data module (for the database PostgreSQL)
u_dm_movimentos.frm
u_dm_movimentos.pas

// The data module reads base-conta.ini file with information for connect to the database

// form working as desired (menu option: Edita Movimentos - CGD)
u_edita_cgd_movimentos.frm
u_edita_cgd_movimentos.pas
// subform of the previous form
u_prep_query_cgd_movimentos.frm
u_prep_query_cgd_movimentos.pas

// form where the problem of assigning datasource to components resides (menu option: de Cartões de Crédito)
u_edita_cc_nb_movimentos.ctrs
u_edita_cc_nb_movimentos.frm
u_edita_cc_nb_movimentos.pas
// sub form of the previous form
u_prep_query_cc_nb_movimentos.frm
u_prep_query_cc_nb_movimentos.pas

Your fixed app conta1.zip attach

1) We:
-ADD to your Project
--u_edita_cc_nb_movimentos.pas and
--u_prep_query_cc_nb_movimentos.pas

-Remove from your project u_prepara_cgd_base_dados.frm



2) We move in u_edita_cc_nb_movimentos the declaration of u_dm_movimentos unit from "Implementation Uses" session to" Interface Uses"

3) Remove u_edita_cc_nb_movimentos.ctrs file it's useless.


4) Work OK now (Win 10 Ent 64Bits, LAB CT 7.2, Typhon64)
