Delphi

Question:
What's the diference between SDI and MDI Applications?

Answer:
An SDI, or single document interface, application has a single, floating menu bar. Each form in the application has its own window, separate from the menu bar.

An MDI, or multiple document interface, application has a parent window, which contains the menu bar and an area where any form windows created in the application exist. If you minimize an application form, it becomes an icon at the bottom of the parent window.

You can display the same OPO application as either an SDI or MDI application by using the -SDI or -MDI switch with the appropriate PORun.exe file for your particular environment, such as

porun32.3exe -MDI test.po
