.DLL add-ins get opened as garbage-text when opened in 32-bit Excel, and succeed in 64-bit Excel.

Have only tried on Excel 2016

Do you think this is a quick fix? I might look into the source code of Excel-DNA to see how they succesfully wrapped the Excel C API for 32 and 64 bit versions.

Currently looking at this particular file

I can't see that functionality in the code, so I assume it's still a work in progress?

Other than that, very useful library, I'm using it extensively to create simple UI's in Excel - calling UDF Rust functions.

I have some heavy calculations to do and would love to make them async if possible. Basically a huge number of cells that each would use a given formula that I implement in rust.

Could you help me out on how I would make that formula async so it runs faster?
I have about 350000 rows and sequentially calculating them takes ages.

Hi Marcus,

I was wondering if you know of how I might be able to call the xlc functions using this. Typically, this is done with the Excel12(...) or Excel12v(...) functions.

#[no_mangle]
pub extern "stdcall" fn xlAlert() -> LPXLOPER12 {
  let result = Box::new(Variant:;from_str("Tried to alert"));
  let alert_text = Box::new(Variant::from_str("Hello from Rust"));
  let alert_text_xloper = Box::into_raw(alert_text) as LPXLOPER12;
  unsafe {
    Excel12(xlcAlert as i32, alert_text_xloper, 1);
  }
  Box::into_raw(result) as LPXLOPER12
}

I get an "unresolved external symbol" error
