Hi,

This article[^] of mine should help you out for most issues.

Yes it may take some experimenting; however for optimum progress, you should fix issues in this order:
1. The stack problem should be solved through the CallingConvention attribute.
2. The numeric parameters or fields should pose no problem, just make sure you use the managed/unmanaged types with matching sizes.
3. The fixed-length string field takes a MarshalAs with SizeConst (not sure a symbolic constant is acceptable); I expect ByValTStr is right, the doc says:
Used for in-line, fixed-length character arrays that appear within a structure. The character type used with ByValTStr is determined by the System.Runtime.InteropServices.CharSet argument of the System.Runtime.InteropServices.StructLayoutAttribute applied to the containing structure.

Good luck

Smile | :)
