Hi!
Iwant to start a webbrowser from a Delphi-program and I use the following
command:
ShellExecute(handle,'open',browser,url,nil,SW_SHOW);
I want the user to specify the browser-path; for example:
d:\programfiler\internet explorer\iexplore.exe
The problem is to convert the string into a Pchar. The following procedure
almost work:
Procedure convertStringToPchar(myString : string; var pch: PChar);
var ch               : array[0..60] of Char;
        i                 : integer;
begin
    //empty the array
    for i:=0 to 60 do begin
       ch[i]:=chr(32);
    end;
    for i:=0 to length(streng)-1 do begin
       ch[i]:=MyString[i+1];
    end;
    Pch:=ch;
end;
The problem with this is that if myString:='d:\programfiler\internet
explorer\iexplore.exe' the
pch:='d:\programfiler\internet explorer\iexplore.exe           ' <----up to
60, and the the browser refuse to start.
Anyone know how to remove the spaces, or know a better method to this??

    I think the more simple is to use this to convert the string to Pchar :
    var
        p:pchar;

    begin
    p:=pchar('the string to convert');
    end;

    I hope it resolves your problem.

Which version of Delphi are you using? New versions have all the pchar
routines built in.

pch:=stralloc(length(mystring)+1) {create space for the #0 char}
strPcopy(pch,mystring);

// now do someting with pch

strdispose(pch);

try...
ShellExecute(handle,'open',@browser[1],url,nil,SW_SHOW);

It's better to use this instead of type-casting.

  StrPCopy(Dest: PChar; const Source: string);
