What is the difference for C-Hook between Mastercam X and X2

[sigmawave]

I started my C-Hook development with X2. After the X3 was released, I update my program to make it compatible with X3.

 

Today I tried my C-Hook(built with X2 SDK) in Mastercam X MR2. It doesn't work.

 

Anybody can tell me the changes between the X and X2 SDK.

 

Any help will be appreciated.

I am just guessing here, but it is enough to change a structure, by inserting another member for example. If the new (X2) layout is used to compile your C-hook, you can not make a function call with it into the old (X) Mastercam, because the function will read/write information from the offsets in the structure that do not match the new layout.

 

There are numerous other possible causes, like changing the number of parameters of a function.

Libraries are not identical between releases. We rebuild, and this means that any change in a header file is going to change call signatures, and functions are not guaranteed to even be in the same place. Also, as markov said, the definition of basic structures and classes (like ent and operation) change between releases, often growing in size as more data is added.

 

You need to rebuild with the SDK for the version you are aiming your chook at.

Rather than a change in SDK, I believe the real significant change was in the underyling architecture of C-Hooks. Prior to X2, C-Hooks were built as "WinApp" dlls. With X2, they are now built as "Extension" dlls. This added a significant change to the way the C-Hook is accessed within Mastercam. This change was reflected in the C-Hook wizard. So, if you use the wizard as the starting point for your C-Hook, your skeleton code will be built to work with the underlying Mastercam archtecture.

Thank for everybody.

I use the Mastercam X SDK to recompile my C-Hook.

 

I can call the dll. But when the dialog(modal) appears, it seems the initialdialog even doesn't work.

 

I think there is a issue in the archetecture.

 

I really appreciate your help.

I compiled the demo project. I run it in the Mastercam X. It can run. But all the resources disappear. For example: all the captions of the buttons disappear. And the buttons can not react the click event. At this time you have to terminate the Mastercam thread.

 

I don't know how to stick a image. Otherwise I can post the picture.

 

Anybody can give me a demo case with the modal dialog?

 

Thanks!

sigmawave,

 

"I run it in the Mastercam X."

 

Exactly which version of Mastercam are you using? X? X2? X3?

I assume that the CHook was built using the SDK for that specific version of Mastercam?

[sigmawave]

HI, Thank you for your reply.

 

I built it with Mastercam X MR2 SDK and Visual Studio 2005. I run it in Mastercam X MR2. (Not X2, X3)

Mastercam X MR2

 

I've got nothing that old that I know of.

If I do, it's in an archive on one of my external drives, so I'll have to dig around and see what I can find for an example project for that version.

-or-

If you wish, send me a zipped up copy of your CHook project and some screen shots/explanations of what's happening and I may be able to assist.

Send me an email via the email icon on this posting and I'll respond with and email address to can send to with your attachment.

Roger, Please check your email.

Thanks!

This is just to clarify on what Mike H. said earlier...

This line should have been ->

 

With X3, they are now built as "Extension" dlls.

Please check your email, Roger.

Thank you!

sigmawave,

 

In the Project1 you supplied, looking at the Start.cpp file tells me that this DLL is being built as an MFC "extension" style DLL.

code:

---

static AFX_EXTENSION_MODULE StartDLL = { NULL, NULL };

---

I must assume that this Chook project was created using the CHookWizard for version X3.

 

*The use of the "extension" style DLLs came about in Mastercam X3.

For versions of Mastercam prior to X3, your CHook must be a "regular" DLL (one that is derived from CWinApp).

Regular DLLs Dynamically Linked to MFC

I will try. Thanks a lot!
