Newbie on the road has just started to learn after the Delphi intends to use it to develop some small desktop application compatibility problem know nothing about the program, so want to ask, for example, I developed a small program (calculator) what needs to be done to make the program under XP 32 bit and Windows 7 64 - bit can run?

CodePudding user response:

What also don't need to do

CodePudding user response:

Compiled for 32-bit programs often is 32/64 system compatible, unless you use a certain system apis, such as GetTickCount64, not on XP, Vista can support at least,

CodePudding user response:

Basically can be run directly, after Delphi2009 version support Unicode, suggest using more than 2009 version

CodePudding user response:

Basic is not affected, as long as you don't use 32-bit assembly,

CodePudding user response:

reference 4 floor lyhoo163 response:

basic is not affected, as long as you don't use 32-bit assembly,

Also can use 32-bit embedded assembly, I tried

CodePudding user response:

Before I make development on 32-bit Windows xp, then directly with a 64 - bit Windows 7 development, development of all program execution on the 64 there is no problem

CodePudding user response:

Now I write client information system are developed in a 64 - bit machine, some of the client computer or 32-bit, running smoothly, safe development,

CodePudding user response:

XE start based on 64 - bit application framework, also have a 32-bit application framework based on
General 32-bit DELPHI program on WINDOWS are clear
