Here is how to integrate your DLL in ProjectWise Explorer

Lotfi,

Well, not exactly.  You are actually doing two different things in your approach.  The registry entries that you are making with the Custom Module Manager are for initializing Custom Modules, which you can use to do various things, typically add hooks, custom menus implemented by API calls, etc.  This "works" only because of what you have done with the Menu Editor tool.  The function that you define with the Custom Module Manager is defined as having a specific function prototype and depending upon what you return, with either keep your module (dll) loaded, or it will unload your DLL.  Take a look at the documentation under Modules > ProjectWise DMS API > Iitialization Functions, as well as searching for "Custom Module" (or Customer NEAR Module).

A few tips from the PW SDK training:

If you are using MFC with dynamic linking, your initialization function should look something like this:

/******************************************************************************

Add your custom initialize function here. Make sure that you export it.
Look at previous labs for the prototype or search the SDK samples for
"CustomInitialize".

Note:
All we need to do is return IDOK
as we will set the hooks in CMyHooks01App::InitInstance()

Don't forget to add the AFX_MANAGE_STATE macro
as described at the top of this file

*******************************************************************************/
extern "C" LONG CustomInitialize
(
ULONG ulMask, /* i Application Mask */
LPVOID lpReserved /* i Reserved (must be NULL) */
)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());

TRACE(L"CustomInitialize() called...\n");

/* add your initialization code here if you don't use ::InitInstance() to do so */

return IDOK;
}

Or like this if you are using a "Win32 DLL" (you need to make sure that your initialization calls are only done once, hence the static BOOL) :

What you are doing with the Custom Module Manager has nothing to do with what you are showing with the Menu Editor tool.  The menu editor tool allows you to add or modify menu items.  The way that it works is when ProjectWise Explorer starts, it looks for .mrr files in the "bin" directory (and only in the bin directory).  For each .mrr file found, if the functions specified for a menu item are not exported, or are not found, or if the dll doesn't exist, no error is reported, and the menu item is ignored.  These too have specific function prototypes defined in the help under ProjectWise API Documentation > ProjectWise SDK Tools > ProjectWise Menu Editor.  Look under "Function prototypes".  If you need more control over ProjectWise menus, take a look at the sample "MYMENU" which doesn't use a .mrr file.  Since your function (defined as for a "Document Command") doesn't match the expected prototype, you are likely corrupting your stack, or at least setting yourself up for a crash, sooner or later.

Hi Dan, in ProjectWise SDK help document where is the function declaration of hoot initialization function "CustomInitialize"? Thank you.

A couple of things:

• "CustomInitialize" is a module "initialization function, not for any specific ProjectWise "feature" such as hooks, it is the function that is called when a ProjectWise application, such as ProjectWise Explorer starts up. Actually a call to aaApi_Initailze(), which is required to use the APIs, is what actually loads your custom module(s). The function's name can be anything as you specify the name in the Windows Registry (done by the Custom Module Manager tool during development).
• The function prototype for "CustomInitialize" is actually NOT documented in the help!! :-(  but you can find examples in some of the samples provided with the SDK. :-)
• If you search the help for "hook" you will get a very long list, but if you search for "hook functions", and enclose the string in double quotes, the lis is very short and if you select one of the results with a title of "Hook Functions", and then click on the "Locate" button in the toolbar, you will find the starting point for the details of hooking in ProjectWise.

To "initialize" any hooks, you call aaApi_AddHook() from the "CustomInitialize" function that you register.  Take a look at the "hookimpl.cpp" file in the samples.

Thank you Dan for the information.
