Hi All, I wrote a Multi-Tier program which has Transaction function. The program runs porperly when the three Tier(Client program, Application Server,DataBase Server) are at the same computer. I mainly use DCOMConnection,ClientDataSet,DataSource,DBNavigator ,DBGrid in client program. The major objects I use in the Application Server are Database, Table and TDataSetProvider. I use BDE to connect to the 'BCDEMOS' database which comes with C++Builder5.0 . Finally I copy the client program and releated files to another computer and try to run the client program.The client program does start and the Application server startups automatically. The functions such as insert, delete, modify, cancel and close work porperly,but when I try to save the records the following message window show up: |-------------------------------------------------------------| | IsBound()@F:\PROGRAM...\VCL\utilcls.h/4140 | | | | Press[Y]es to terminate [N]o to continue [C]ancel to DEBUG | |-------------------------------------------------------------| Press "Yes" lead to the following message: "IsBound() failed F:\PROGRAM...\VCL\utilcls.h/4140" Press "No" lead to the following message: "EAccess Violation" Press "Cancel" lead to the following message: "External exception 80000003" Anybody meet with the same problem?How to solve? Thanks!
