[A v i]

Today, I had the pleasure of going through Side's DLL Call Tutorial.

 

Pretty Impressed,I tried to do some tests on how other DLL's work following this MSDN page.

 

But , thats a huge list..Too Long for trying them one by one..

 

So, can any DLL CALL Expert suggest a good list of interesting,helpful (DLL) functions that are only possible with DLLCall and not with just AHK. () .Some fucntions that are really must-try.

 

As for Side's Tut, he used MessageBox to teach the concepts ; MessageBox which is also possible with AHK

nothing is 'important' or 'must-try'

you use what you need to reach your goal. what is your goal? to just play around? then just look thru the Scripts forum

If you are still looking, I suggest you play with music, using bass.dll and audiogenie3.dll

Can these add/edit Id3 tags..

I see you Mod

I don't personally use the libraries for AG3 or Bass myself, though.

Unicode wrapper for bass

 

Here are some DllCalls I use frequently.

• Include any file in script - I don't understand how it works, I simply use it
• Hook onto shell
• WinEventHook messages - Superset of above if used well enough, can be used to detect Ctrl-Alt-Del screen, although I am unable to find a practical use for this.
• ClipCursor
• EnumWindows - perform actions on all windows, one by one. EG Hide them.
• RegisterPowerSettingNotification - Able to detect monitor off, laptop screen shut or open, etc.
• Block keyboard, and unblock it through usage of keyboard - Example below.

Call it as BlockKeyboard(true)

See password within code, press those keys in order to unlock.

BlockKeyboard(block=-1) ; -1, true or false.
	{ ;Thanks to Lexikos
	static hHook = 0, cb = 0
	if !cb ; register callback once only.
		cb := RegisterCallback("BlockKeyboardProc","Fast")
	if (block = -1) ; toggle
		block := (hHook=0)
	if ( (hHook!=0) = (block!=0) ) ; already (un)blocked, no action necessary.
		return
	if (block) 
		{
		hHook := DllCall("SetWindowsHookEx"
		, "int", 13 ; WH_KEYBOARD_LL
		, "uint", cb ; lpfn (callback)
		, "uint", 0 ; hMod (NULL)
		, "uint", 0) ; dwThreadId (all threads)
		}
	else
		{
		DllCall("UnhookWindowsHookEx", "uint", hHook)
		hHook = 0
		}
	}

BlockKeyboardProc(nCode, wParam, lParam)
	{
	static count=1, Keys:=["r","F12","LCtrl",".","CapsLock"]   ;password, some keys don't work, beware!
	if (NumGet(lParam+8) & 0x80) 
		{
		if (NumGet(lParam+4)=GetKeyHex(Keys[count]))
			count++
		else
			count=1
		If (count=Keys.MaxIndex()+1)
			BlockKeyboard(false)
		}
	return 1
	}

GetKeyHex(Key)
{
	OldFormat:=A_FormatInteger
	SetFormat, Integer, H
	Ans:=GetKeySC(Key) + 0
	SetFormat, Integer, % OldFormat
	return Ans
}

 

In most cases, the documentation of the function in the DLL, combined with AHK documentation is able to explain things to me.
