delphi - How to edit a file using a specified editor? -


currently, i'm using following function in order open file using default editor , sure application waits until user closes editor window.

function editandwait(const afilename : string) : boolean; var   info: tshellexecuteinfo; begin   fillchar(info, sizeof(info), 0);   info.cbsize := sizeof(info);   info.lpverb := 'edit';   info.lpfile := pansichar(afilename);   info.nshow := sw_show;   info.fmask := see_mask_nocloseprocess;   result := shellexecuteex(@info);   if(result) , (info.hprocess <> 0)    begin     waitforsingleobject(info.hprocess, infinite);     closehandle(info.hprocess);   end; end;

i write similar function allow specify editor executable use editing.

function editandwait(const afilename : string; const aeditor : string) : boolean; begin   //... end;

as david said, have run editor program , pass file parameter.

there several ways it. similar current function:

function editandwait(const afilename : string; const aeditor : string) : boolean; var   info: tshellexecuteinfo; begin   fillchar(info, sizeof(info), 0);   info.cbsize := sizeof(info);   info.lpverb := 'open';   info.lpfile := pchar(aeditor);   info.nshow := sw_show;   info.fmask := see_mask_nocloseprocess;   info.lpparameters := pchar(afilename);   result := shellexecuteex(@info);   if(result) , (info.hprocess <> 0)    begin     closehandle(info.hprocess);     waitforsingleobject(info.hprocess, infinite);   end; end;

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
