Variable global value change

[Alex B.]

In my project, I have a login screen, where the user enters the login and password, I use this information to query the database. When the query returns a record, I assign the value of the record's ID to a variable I declared in my MainModule.

In my MainForm, I put a showmessage for me to check the value of the variable. the problem is that if I log in a user in a browser and then log in another user in another browser, when I try to display the ID of the first user who logged in, the second one appears.

How can I solve this problem? each user must display his corresponding ID in each browser.

If you declare your global variables in main module must be onle for the session is using

Thanks for your response. Yes, I declared my variable in the main module, I put a showmessage in the KeyDown event for the F3 key so I can check the variable's value, but it is changing as you can see in the video.

Hi,

You should not declare a global variable, but a public variable in MainModule class

unit MainModule;

interface

uses
  uniGUIMainModule, SysUtils, Classes, uniGUIBaseClasses, uniGUIClasses;

type

  TUniMainModule = class(TUniGUIMainModule)
    UniNaImLtSistema: TUniNativeImageList;

    procedure UniGUIMainModuleSessionTimeout(ASession: TObject;
      var ExtendTimeOut: Integer);
    procedure UniGUIMainModuleCreate(Sender: TObject);
    procedure UniGUIMainModuleBrowserClose(Sender: TObject);
    procedure UniGUIMainModuleDestroy(Sender: TObject);

  private
  public
    vGlobalVariable: string;

end;
