DllOpen returens -1 dllcall fail

[RaiNote]

May Test that

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Change2CUI=y
#AutoIt3Wrapper_Add_Constants=n
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
$dll1 = DllOpen("DllBasics.dll")
DllCall($dll1,"none","Function")

if u do DllCall the Function will be run and the MsgBox should Pop up

DllBasics.dll

DLLCall.au3

DLLCall.exe

 

Does my work for you and your own too? or still something Bugs?

yea.. not working same problem, I don't understand why it works for you, but for me not. 

thanks for the help anyway

[RaiNote]

Which AutoIt Version?

 

May install Autoit 32bit Version °-°

[TheShaps]

Autoit version 3.3.12.0

[RaiNote]

install latest Version 3.3.14.0 and test it again ^-^ just try everything ^-^

Have you tried simply calling the dll function?

I'm pretty sure you need an entry point function for DllOpen, perhaps you do not for simple DllCall.

[jchd]

Are streams (cin, cout from iostream) part of C now? DllCall is for calling C.

okay update:

so I tried to run the DllCall.au3  that RaiNote  has provided me with, and it totally worked I was in shock!

then I tried to copy the code to my func but it didn't work. 

$dll1 = DllOpen("DllBasics.dll")
DllCall($dll1,"none","Function")
;DllCall($dll1,"none","Function")

but if I got the code out of the function it works, runining it by right clicking> Run Script works. The file is called after the func name. The problem is that if I call the function from the main program it still doesn't work. how do I make it work by calling it from the main function? 

I have included the file name in the main program

even if I change the DllCall.au3 file to this: and add a function  it stops working 

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Change2CUI=y
#AutoIt3Wrapper_Add_Constants=n
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
Func func2()
$dll1 = DllOpen("DllBasics.dll")
DllCall($dll1,"none","Function")
DllCall($dll1,"none","Function")
EndFunc

Thanks for your help guys  !!

You have to call the function.

[Danyfirex]

maybe you need to learn the basic of programming instead walking with closed eyes.

[TheShaps]

of course I am calling the function. it just doesn't work when its inside the function. I am calling it form the main function

[Danyfirex]

did you try your dll from Visual Studio?

 

Saludos

[TheShaps]

Danyfirex

okay mister genius and knows everything. then explain why calling the user32.dll worked but calling my dll from the function doesn't

 "did you try your dll from Visual Studio?" Omg did you even read the post? what do you mean? calling it from visual studio? creating it in visual studio? yes the dll was created in visual studio.

if I was a genius don't be here helping another just for free. 

it That  I said. its just a suggestion. someone genius like me(¬¬)  makes stupids trying to help someone like you. 

Maybe I did not read well. ( I'm not  an English native speaker.) so maybe for that I did wrong.

But I'm sure other people here appreciate the effort that I do for helping them.

good luck with your proyects.

Well you can use it like me with C++ if you use it extern.

Also try using my Project and Maybe u should use Visual Studio 2013 because of bug fixes and some other extras ^-^. and if u could ask Why are there so many "funcs" within my Code just because i was bored and tested something ^-^. If it also don't work with my Project using then something left on you Computer may some .Net Version.

DllCall($dll1,"none","Function")
DllCall($dll1,"none","Function")
EndFunc

Thanks for your help guys  !! 

If you do it with Func func2() you have then to run this Function like. And Why it not working for you is idk why may could you upload your Project? or try it with mine (You could Change everything to what you like but if you do something wrong within the Header everything Ends ^-^)

func2();Function func2() being runned
sleep(250);just a little time out :o

DllExampleCall("DllBasics","Function","none")

Func DllExampleCall($dllname,$dllFunc,$dllreturn);$dllname without dll $dllFunc what Func is being called $dllreturn Return Parameter(1,0,-1,none) i think..
$dll1 = DllOpen($dllname & ".dll")
DllCall($dll1,$dllreturn,$dllFunc)
EndFunc

 

You have to call the function.

He can only call the Function after he Opened the DLL with $dll = DllOpen("DLLname.dll") and using after this DllCall($dll, "none", "Function"); $dll= the dll "None" is the return Parameter so it just called and after this end "Function" is the Name of the Function. 

I hope any of These Infos was helpful :3

p.s.: I don't know anything of using Dll's with AutoIt i just looked up the params for the Command

@TheShaps (reminding)

 

Also would it possible to read with AutoIt What the console writes?:O

 

Just like you are using within the dll std::cing.get();

so that some Value is being read and maybe displayed in a MsgBox.

[JohnOne]

@TheShaps

Are you saying that this works..

$dll1 = DllOpen("DllBasics.dll")
DllCall($dll1,"none","Function")

But this does not...

func2()

Func func2()
$dll1 = DllOpen("DllBasics.dll")
DllCall($dll1,"none","Function")
EndFunc

Also might be wise to adjust your attitude a little @Danyfirex was trying to help you.

[RaiNote]

@JohnOne his Problem is that his Code won't work if he uses it but if he uses mine it work. °-°

That's the main Problem.

Edit:  That it inside of func won't work (because he Forget func2() maybe)
