I’m migrating an application from Delphi 7 that used to be in FireBird and now I’m connecting to the bank PostgreSQL, but a variable error was occurring, with the help of the Stack people, I discovered that it could be the Fields of ClientDataSet that could have to be updated so that no more error occurs. I was able to do this with the dmCadEmpresas, but when I try all the others Fields is occurring the following error:

I did some research and couldn’t find what could be causing it, if you have any idea

delphi postgresql delphi-7

  • Try to have a look if your application contains Midas.dll inside the project folder, because the clientdataset needs this dll to be able to work, or else it declares Midaslib in the uses of the class.

  • I checked and Midas.dll is inside my project folder

  • Regarding Midas, it is better to declare in dpr uses Midaslib.

I recommend that you restore a Backup of this project and redo what I informed you on the other question!

For this:

The Designide package (Designide70.bpl in bin subfolder and Designide.dcp in the lib ) sub-folder serves only for use in the Delphi IDE 7.0 and not in the final applications. Therefore, you should not add it in your final projects or in your component packages.
