Visual C++ 2010 + AutoItX_x64.dll

[ligorlwow]

When in C++ I use LoadLibrary("AutoItX3.dll") functions work , but not correct, for example :

void N_Send(LPCWSTR szSendText, /*[in,defaultvalue("")]*/long nMode)
{
typedef void (CALLBACK* temp)(LPCWSTR szSendText, /*[in,defaultvalue("")]*/long nMode);
HMODULE hDLL;
    hDLL=LoadLibrary("AutoItX3.dll");
temp r;
r=(temp)GetProcAddress(hDLL,"AU3_Send");
r(szSendText,nMode);
}

if N_Send("HELLO WORLD",0) - > result : 慤摳獡D | why??

if N_Send("A",0) -> result: A | work correct(If one character)

If I use a function with int(long) argument, function work correct, for example AU3_Sleep(long nMilliseconds), N_PixelGetColor(long nx,long ny) ...

If I use AutoItX_x64.dll in LoadLibrary, it return NULL | why?? ( Windows 7 64-bit)

Thanks for your help.

You need to use Unicode strings. Prepend an L on the quotes.

L"HELLO WORLD"

You call LoadLibrary each time the function is entered, but CloseHandle is never called. By the way, why don't you link to the dll to create a hard dependency?

how to do it?

[JohnOne]

hDLL=LoadLibrary("AutoItX3.dll");

//do stuff;

CloseHandle(hDLL);

[trancexx]

hDLL=LoadLibrary("AutoItX3.dll");

//do stuff;

CloseHandle(hDLL);

You are interesting person.

how to do it?

I forgot that AutoItX doesn't come with the required .lib files and it is a bit tricky to create them from the dll, but it should be possible.

Want to join my cult?

Sure. What's it called like? Cult of Free Library?

[JohnOne]

Ah! It's now called the cult of "I blame ProgAndy"

[ligorlwow]

Thanks for your help.

[JohnOne]

But wait, should be FreeLibrary(hDLL)

How work 'L' with variables ?

[JohnOne]

You would need to ensure your variables are LPWSTR to begin with

or perform some sort of cast.

I think if your vars are WCHAR var[n] you can pass *var.

[ligorlwow]

Can you use dynamic variables?

And please example, because if I use LPWSTR var, I can not change them and for WCHAR too.

[JohnOne]

Give an example of how you get your variables into your code.

One example might be...

wchar var[256];

wcin >> var;

N_Send(*var,0);

[ligorlwow]

Thanks, but i have two problems:

1) I can't save 'space' in WCHAR variables.("HELLO WORLD" -> result : HELLO )

2) some function do not work, for example wstrcpy()....

I some edited your example:

wchar_t var[256];
wcin>>var;
N_Send((LPCWSTR)var,0);

Give an example of how you get your variables into your code.

For example : file or

InputBox().

[JohnOne]

Then your method of reading a file or InputBox() (which I'm sure is not a C++ standard windows function) would

need to be read into a var of type LPWSTR.

I don't think you need an explicit constness cast either.

[ligorlwow]

Thanks, I figured.
