interop

问题 The aim is to run an OpenCL/OpenGL (interop) app inside a docker container. But I have not been successful yet. Intro I have laptop with an NVidia graphics card so I thought leveraging on NVidia Dockerfiles [1,2] would be a good starting point. The following Dockerfile: # Dockerfile to run OpenGL app FROM nvidia/opengl:1.0-glvnd-runtime-ubuntu16.04 ENV NVIDIA_DRIVER_CAPABILITIES ${NVIDIA_DRIVER_CAPABILITIES},display RUN apt-get update && apt-get install -y --no-install-recommends \ mesa-utils

问题 I'm trying to wrap a custom subclass of UILabel in UIViewRepresentable to use it in Swiftui. I'm using .sizeToFit and printing the frame, and it looks right while it's in the wrapper: func makeUIView(context: Context) -> CustomUILabel { let view = CustomUILabel() view.customProperty = model.customProperty view.sizeToFit() print(model.latex,view.frame.size) // this prints the correct size, how to propagate? return view } but when I run this in a Vstack, it draws the UIViewRepresentable with

问题 I have 2 programs: A Fortran program that does a lot of calculations using intel compiler and Visual studio 2013, Windows 10. It generates a dataintomatlab.dat file as an input for the MATLAB program and receives a dataoutmatlab.dat file from MATLAB. A MATLAB m.file which loads dataintomatlab.dat and save data as dataoutmatlab.dat as an input for the Fortran program. The following code is used to link the Fortran program with MATLAB: result_matlab = SYSTEMQQ("C:\PROGRA~1\MATLAB\R2019a\bin

问题 I'm trying to show the system menu (containing minimize, restore, etc.) from a different process in my WinForms UI. I understand that I need interop calls like GetSystemMenu and TrackPopupMenuEx but I failed to make it work. Can someone provide a sample code how to do it? I've found this code snippet (for WPF): Open another application's System Menu I modified it to something like this: const uint TPM_LEFTBUTTON = 0x0000; const uint TPM_RETURNCMD = 0x0100; const uint WM_SYSCOMMAND = 0x0112;

问题 I have this exception that is driving me crazy.

问题 How can I use the Swift Package Manager to include C code (in my case, a single .c file and a header file) without requiring the user to install my C library into /usr/local/lib ? I had thought to create a Package in a subdirectory of my main package containing the header + lib, and use relative paths, and finally build with swift build -Xlinker ./relative/path/to/mylib , however I'm not having any success resolving the dependency since it's expected to be a standalone git repository.

问题 I'm trying to connect to a running Excel instance, but when I try to use the following code snippet: using Microsoft.Office.Interop.Excel; using System.Runtime.InteropServices; public Application StartExcel() { Application instance = null; try { instance = (Application)Marshal.GetActiveObject("Excel.Application"); } catch (COMException ex) { instance = new ApplicationClass(); } return instance; } I found similar snippets on the internet, but when I compile this code I get the following error:

问题 I am trying to open a .dat file in Excel, which is tab delimited, and then have it save out as a .xls file. So far, I can read in the file and save it as the .xls file but for some reason, all the values are in the first column and it does not tab delimit them. (If I open up the file in Excel without my program, it tab-delimits perfectly) These are the two lines of code that I am using to open and resave the file. xlWorkBook = xlApp.Workbooks.Open(f, 0, true, 5, "", "", true, Microsoft.Office
