Hi there?

I want to open a file by dragging it to the shortcut to a program, and then the program will start and open the file for me. For example. i can drag a TXT file on the on the shotcut to the NOTEPAD.EXE, and then the file will be open and displayed.

Thank you in advance!

I'm sorry that i did't put any comments in the source but right now i don't really have the time for that,so if you need some,later maybe i will put some explanations!

This might help!

HowTo - Handle the double-click/dropped file(s)

.code
start:
	; --- cut ---
	invoke GetModuleHandle, NULL
	mov    hInstance,eax
	; --- cut ---
	; Get the commandline args (like when dragging files into the editor icon)
	; CmdLine: "C:\Dev\Projects\SciASM\SciASM.exe"C:\Dev\Projects\Hello.txt
	invoke GetCommandLine
	mov    CommandLine,eax

	; Get command line filename
	invoke PathGetArgs, CommandLine	; Win32 shell path functions
  @@:											; MasmEd
	mov dl,
	.if(dl==VK_SPACE)
		inc eax
		jmp @b
	.elseif(dl=='"')
		invoke PathUnquoteSpaces, eax	; Win32 shell path functions
	.endif
	mov CommandLine,eax

	invoke WinMain, hInstance,NULL, CommandLine, SW_SHOWDEFAULT
	invoke ExitProcess,eax


WinMain proc uses edx, hInst:HINSTANCE,hPrevInst:HINSTANCE,\
								CmdLine:LPSTR,CmdShow:DWORD
	; --- cut ---
	; Get command line filename
	; Note: We had a
	;			1) filename double-click or 
	;			2) a filename dropped on the application icon
	xor eax, eax
	mov edx, CmdLine
	mov al, 
	.if(al)
		; Handle the double-click/dropped file(s)
		invoke ProcessCommandLine, CmdLine
	.else
		; Initialise a new document and set the lexer
		invoke NewDocument	
	.endif 
	; --- cut ---
	.while TRUE
		invoke GetMessage, addr msg,NULL,0,0
		.break .if(!eax)
		; --- cut ---
	.endw

	ret
WinMain endp


; ProcessCommandLine
; Ref : SciTEBase::ProcessCommandLine()
; Desc: Process the commandline and open any filenames passed
; Note: We had a
;			1) filename double-click or 
;			2) a filename dropped on the application icon
; @param		lpchArgs		Command line parameters
; @returns	boolean
ProcessCommandLine proc uses esi, lpchArgs:dword
	LOCAL nCnt:dword

	; Command line parameters: lpchArgs
	; ~~~~~~~~~~~~~~~~~~~~~ ;
	; Note: The Win32 shell path functions (GetCommandLine & PathGetArgs) should
	; 			have removed any filename spaces (in dropped files).
	; Note: There is a space between multiple files
	; Single file: something like "C:\Dev\Xxx.txt"
	; Multi files: something like "C:\Dev\Xxx.txt C:\Dev\Yyy.txt"

	; --- cut ---
	; Please refer to the SciTE source for detail:

	; --- cut ---

	ret
ProcessCommandLine endp
