I see it in ntdll.def. But seems there's no rust source code about it in winapi-rs crate. And I think it may concerns bindgen.
anyway, is there a way to call that function? It's quite complicated for me...
plus or minus 20%
the windows sdk is huge
i'm finding that there's no easy way to go from
OsStr to a const * _?
@bzm3r As for your
ID3D10Blob question, you would call the GetBufferPointer and GetBufferSize methods to get the pointer and size, and pass them to std::slice::from_raw_parts to get a &[T].
If the blob is a unicode string you would get a
&[u16] and pass it to OsStringExt::from_wide()
it'll be better in winapi 0.4 which will use actual unions
Can anyone tell me why this code is failing on
CoCreateInstance with a class not found error? https://github.com/LiHRaM/egpu-rs/blob/master/src/main.rs
the
HRESULT specifically is: 0x80040154
small issue here, I can't figure out how to import
tlhelp32error[E0432]: unresolved import `winapi::um::tlhelp32`
import
winapi::um works though
ok, i have to enable a feature to gain access to tlhelp32
lihram This is the relevant windows documentation for C++
lihram Nvm, found it here: https://github.com/contextfree/winrt-rust/blob/master/examples/toast_notify.rs
Hi,
I am trying to use UIAutomation in my project.
I've found out only https://lib.rs/install/uiautomationcore-sys
But there is no documentation how to use it. Maybe anybody knows or there is better way? Thanks!

Hello, I'm struggling with following problem:
I have a BITMAP declared like this
let mut bmp: BITMAP = mem::uninitialized();then I'm trying to call a GetObject
GetObjectW(
bitmap as HANDLE,
mem::size_of::<BITMAP>() as i32,
&mut bmp as * LPVOID,
);And I'm getting
error[E0606]: casting `&mut winapi::um::wingdi::BITMAP` as `*mut std::ffi::c_void` is invalid
--> src\main.rs:118:17
|
118 | &mut bmp as LPVOID,
| ^^^^^^^^^^^^^^^^^^
I've tried different combinations of types in cast expression but still cannot find a correct one
@rucoder_gitlab Alternatively
<*mut _>::cast(&mut bmp)
as I understand the rule here is : "cast reference to the pointer of the same type and then reinterpret pointer with second 'as'"
hi there! it was probably asked a zillion times, but how do I get data back? I'm trying to get the returned value
pvData and pcbData from a call to winapi::um::winreg::RegGetValueA... the function returns ERROR_SUCCESS if I set those both to std::ptr::null_mut(), so all other parameters are OK! I'm just stuck on how do declare those variables and converting then to and from... I'm new to rust!!!
ok, did it! the solution is always simpler than we think....
let mut pvData = vec![0; 2];
let lstatus = unsafe { RegGetValueA(HKEY_CURRENT_USER,
hkey.as_ptr(),
lpSubKey.as_ptr(),
RRF_RT_REG_DWORD,
std::ptr::null_mut(),
pvData.as_mut_ptr() as *mut c_void,
std::ptr::null_mut()
)};
println!("SUCCESS {:?}", pvData[0]);
