Hi,

I'm trying to execute an external program with the shellexecute API. The exteranal program needs rather a lot of parameters in order to run correctly however; i.e. c:\dir\progname.exe -para1 -para2 etc.

How can I do this in Delphi? Idealy my program will generate the parameters at run time.

Thanks,

BTW, the external program is xplanet - a you can find more information at http://xplanet.sourceforge.net. I'm attempting to create a small [simple] launcher for it.

hello alza, you could try something like this -
add ShellApi to your uses clause

implementation

uses ShellApi

var
ExePath, SendParam: String;
begin

  ExePath := 'C:\Folder\Exe.exe'
  SendParam := Param1+' '+Param2+' '+Param3;

  ShellExecute(Handle,
'open',     // pointer to string that specifies operation to perform
    PChar(ExePath),     // pointer to filename or folder name string
    PChar(SendParam),     // pointer to string that specifies executable-file parameters
    nil,     // pointer to string that specifies default directory
    SW_SHOW      // whether file is shown when opened
   );

end;

Hello and thank you to you both.

Slick812;
I've implemented a simple edit box where the parameters can be entered and then assigned to a string (SendParam). This seems to work fine at the moment.

I'm not entirley sure how and where the functions you've mentioned come into it. I've tried using paramstr(0) and this just returns the path of my compiled program...

Thanks,

paramstr contains parameters that were used to run the current program, where paramstr(0) (the first one) contains the executable name.
