With Delphi XE compile the old version of the VCL, always appear the compiler error, excuse me, how to solve? Thank you very much!

CodePudding user response:

Used XE, possible only Settings like vs the character type can make a bad conversion

CodePudding user response:

Mainly, caused by the use of PChar Dephi7 PChar mean PAnsiChar, by D2010, default refers to PWideChar
Therefore, you need to change the content for PAnsiChar PChar related.

CodePudding user response:

Agree with upstairs
Pchar into PAnsiChar
I now use the 2010 is in the same situation before

CodePudding user response:

Find a lot of control error even changed, XE still is not working

CodePudding user response:

CodePudding user response:

refer to the second floor response:

mainly, caused by the use of PChar Dephi7 PChar mean PAnsiChar, by D2010, default refers to PWideChar
Therefore, you need to change the content for PAnsiChar PChar related.

Thanks for sharing, I also in research and study the DELPHI XE in

CodePudding user response:

This is the code under the D7 completely normal:

Var tem: DWORD;
The begin
Tem:=htonl (ntohl (inet_addr (Pchar (edtPing1. Text))));
ShowMessage (IntToStr (htonl (ntohl (inet_addr (Pchar (edtPing1. Text))))));
ShowMessage (inet_ntoa (in_addr (tem)));

end;

This is a test of under 2010, but the result is not the same, edt1. The text value of the IP address
Var tem: DWORD;
The begin
Tem:=htonl (ntohl (inet_addr (PAnsiChar (edt1. Text))));
ShowMessage (IntToStr (htonl (ntohl (inet_addr (PAnsiChar (edt1. Text))))));
ShowMessage (inet_ntoa (in_addr (tem)));
end;

All turn native String String types PAnsiChar need after AnsiString transition
Tem:=htonl (ntohl (inet_addr (PAnsiChar (AnsiString (edt1. Text)))));
You can try this one, I in D2010 solve the prompt,

Call API function gethostname Error: [DCC Error] uVIMPublicFun. Pas (449) : E2010 Incompatible types: 'Array' and 'PAnsiChar'
Var
The hostName: an array of char [0.. 255];
The begin
Gethostname (hostName, sizeof (hostName));
end;
Causes: D2009 WideChar Char as wide characters, and gethostname the first parameter is the PAnsiChar,
Solution: change the hostName of the statement to array [0.. 255] of AnsiChar; Can,
