dll

问题 When I launch .exe it gives error MSVCP120.dll is missing. How do I add statically link to project. Is it in Linker? Do I need to give path to MSVCP120.dll? 回答1: In general, you should not use static CRT linking as it creates a number of potential problems, security risks, and servicing concerns. You can require the VC++ REDIST package to be run (which requires admin rights) to install the 'system' version, you can use the VC++ MSM modules with your own MSI installer, or you can just use side

问题 I have an abstract base class which is written with c++/cli. This class is located in a project. And i have other projects which inherit the abtract base class. So, the structure is like the following. Base Project: public ref class Base abstract { // implementation virtual CommonFunc(); }; public delegate void Foo(); Derived Project A: public ref class A : public Base { // implementation }; Derived Project B: public ref class B : public Base { // implementation }; And, so on. I can call both

问题 I am just new in Python. I am trying to connect to a laser sensor through its DLL library. The SDK functions in this Library are compiled in C++ language. By using ctypes in python my first try is to call the EthernetScanner_Connect function. The function parameters are as follow: void* EthernetScanner_Connect(char *chIP, char *chPort, int iTimeOut) According to the function discription in c++ it should return NULL pointer if a failure in connection occurs, otherwise it should return the

问题 What is the proper way to load in a dynamically linked library (i.e., a .so file) when writing an R package? The only solution that has worked for me so far has been to specify the full path to the .so file, e.g.: dyn.load('/FULL/PATH/TO/MY/R_PACKAGE/src/my_file.so') Obviously, this approach will not work for a CRAN/Bioconductor submission since the .so file will not be located. As such, I have (unsuccessfully) tried the following alternatives: 1) library.dynam() 2) library.dynam('my_file.so'

问题 I have found that when I add new events to an existing COM/IDL interface, I sometimes run into strange issues unless they are added to the end of the interface. For example, say I have the following interface: interface IMyEvents { HRESULT FooCallback( [in] long MyParam1, [in] long MyParam2, [in] long MyParam3); HRESULT BarCallback( [in] long MyParam1, [in] BSTR MyParam2, [in] BSTR MyParam3); }; Now let's say I want to add a new callback event, NewCallback . If I add it like this, I tend not

问题 I'm trying to use a dll, namely libcurl, with my program, but, it's not linking. Libcurl comes with .h files that I can include (takes care of dllimport), but then I guess I must specify which dll to actually use when linking somehow... How do I do that? I'm compiling with Borland C++ builder, but I really want to know how these things work in general... EDIT: This is the code (straight c/p from curl homepage) bool FTPGetFile::ConnectToFTP(string ftpServer){ CURL *curl; CURLcode res; curl =

问题 I understand that such an error has been discussed multiple times on SO. Some turned that was a bug in DLL file, some resolved by changing DLL version, other didn't seem to have a clue. Anyway I just post to try my luck: My application crashed when selecting a row in a grid on a C# GUI. The stackTrace looks like: System.NotSupportedException: The invoked member is not supported in a dynamic assembly. at Oracle.DataAccess.Types.OracleUdt.GetAllReferencedAssemblies() at Oracle.DataAccess.Client
