Cant run win32ole with node-webkit

[danielabelski]

Hi! Tried to use the module in node-webkit and could not. After calling the module [ var win32ole = require('win32ole'); ] node-webkit crashes. With pure node it works ok. But we never had issues with other modules working with node-webkit. Any clue why this might be happening?

Have you tried building the app with nw-gyp? Since node-win32ole is a native app it appears there is a separate process for building it for node-webkit.

I am also interested in using node-webkit in a project. If you do get this to work with nw-gyp please report back. Thanks!

Chose the way of using win32ole with pure nodejs and not node-webkit, but it leaks memory a lot and I cant fix this as C++ is not my thing))) They #5 have the same problems, so I am waiting for the author to answer, or a solution to come.

Hi,
I have builded the app with nw-gyp and I got the same result : node-webkit crashes when it call "require('win32ole');"
Do you plan to do make it compatible with nw ?
Thanks

FWIW, win32ole also works for me under node.js (v0.10.20) but won't compile for node-webkit (v0.7.5) because of errors when running nw-gyp (v0.10.9) rebuild. I'm using python 2.7.5 and Visual Studio Express 2012. Perhaps an issue for node-webkit and not this project, though.

From "nw-gyp rebuild --target=0.7.5" ::

I have an error with node-webkit when i use win32ole:
%1 is not a valid Win32 application

What can i do?

I've been trying to get this working for some time -- I'd actually pay for the ability to use this within node-webkit. Or any other module which lets me talk to windows from JS via COM. I have looked at the way python does this with the win32 module, looked at how this can be implemented in C etc.

It turns out that this is not a trivial task. The windows program (PTC Creo 3D cad system, has a VB interface) I want to talk to uses custom "objects" which get serialized etc. One would need to parse the relevant object descriptors in JS -- the python win32 module does this.

Also the C++ code is quite confusing IMHO, so ...
