Interfacing device visa USB in MATLAB using C DLL files

由 北慕城南 提交于 2020-01-16 19:33:32
问题 I am doing a project in which i have to interface a device via USB using MATLAB. The API (dll files) of the device is written in the C++ so i used loadlibrary command in MATLAB to load it and done interfacing. It's working fine. The problem is that when i run the program from MATLAB it works fine but for running it again i need to plug out the device and then plug in to make it run successfully. But i wrote a C++ interface that is working fine. Can anyone tell me what should i do? The problem

Not finding function using GetProcAddress() C++ VBexpress 13

问题 Okay so I'm coming dangerously close to a repost here but my situation is a little bit different than the numerous other posters about this function. I am interfacing with a DLL that was written way back in the day and all I have is the file. I don't have a .lib file so I'm using the LoadLibrary and GetProcessAddress functions. I followed the tutorial on the MSDN website to get the basic structure. the DLL is located in the project folder. it compiles. at run time, I am getting a numerical

DllImport vs LoadLibrary, What is the best way?

问题 i'm usually using Win32 API in c#.NET. But not declare all in one application. Sometimes usually using user32, sometimes gdi32 ... I think when i declare all api function, those use lot of memory. What is the best way using API in .NET ? 回答1: Most of the Win32 API is available through managed abstractions. Otherwise, declare the ones you need using DllImport . LoadLibrary should really only be used where you have provided alternate functionality, that is, your application can work even

参考了这个博客： https://blog.csdn.net/cuglifangzheng/article/details/50580279 以及这个博客： https://blog.csdn.net/zhangbohh8662/article/details/47026519 若DLL不在调用方的同一目录下，可以用LoadLibrary(L”DLL绝对路径”)加载。 但若被调DLL内部又调用另外一个DLL，此时调用仍会失败。解决办法是用LoadLibraryEx： LoadLibraryEx(“DLL绝对路径”, NULL, LOAD_WITH_ALTERED_SEARCH_PATH); 通过指定LOAD_WITH_ALTERED_SEARCH_PATH，让系统DLL搜索顺序从DLL所在目录开始。 跨目录调用dll，你应该这样 1 用GetCurrentDir保存当前的工作目录 2 用SetCurrentDir将当前的工作目录，设置为你的DLL所在的路径，需要使用绝对路径 3 用LoadLibrary你的DLL 4 使用SetCurrentDir恢复到原来的工作路径 上面的方法不行的话， 试下： 若DLL不在调用方的同一目录下，可以用LoadLibrary(L"DLL绝对路径")加载。但若调用的DLL内部又调用另外一个DLL，此时调用仍会失败

Dynamically linked DLL is loaded immediately after starting the application

问题 I've dynamically linked libhunspell.dll (HunSpell) to my application. It works, but there is a dumb problem which I don't know why it happens. Even before I use LoadLibrary("path\\to\\libhunspell.dll"); to load it and use it, on the start of the application it attempts to load the library by itself. If I place the libhunspell.dll into the path where my main executable resides, it can load it, otherwise it reports an error, immediately after starting the application - This application has

getting libstruct to work in matlab for dll pointer argument

问题 I'm trying to call a dll function in matlab. I have a C++ struct as shown in sixense.h: typedef struct _sixenseControllerData { float pos[3]; float rot_mat[3][3]; float joystick_x; float joystick_y; float trigger; ... } sixenseControllerData; and functions I could call: SIXENSE_EXPORT int sixenseInit( void ); SIXENSE_EXPORT int sixenseGetAllNewestData( sixenseAllControllerData * ); I can easily get this to work with calllib('sixense','sixenseInit') since there is no input, but for the
