call c++ dll by using loadlibrary #92

Open ricky-yi opened 5 years ago

ricky-yi commented 5 years ago

Everything works when the environment setup with option I.

And because my dev machine can't connect to Internet, I use option 2 to setup node-gyp, it works ok but loading c++ dll with loadlibray, compile succeed, but run error by returning NULL handle.

are there any configure options should be set in option 2.

Thanks.

Following are the 2 options:

Environment setup and configuration: •Option 1: Install all the required tools and configurations using Microsoft's windows-build-tools by running npm install -g windows-build-tools from an elevated PowerShell (run as Administrator). •Option 2: Install dependencies and configuration manually i.Install Visual C++ Build Environment: Visual Studio Build Tools (using "Visual C++ build tools" workload) or Visual Studio 2017 Community (using the "Desktop development with C++" workload) ii.Install Python 2.7 (v3.x.x is not supported), and run npm config set python python2.7 iii.Launch cmd, npm config set msvs_version 2017

my code: HMODULE hdll = LoadLibrayA("xxx.dll"); if(!hdll) { cout << "error: " << GetLastError() << endl;

when running, hdll is null and error code is 0 which means run successfully.
