CWindow Release Candidate 31

[José Roca]

I have finished the work. ColeCon and CWebBrowser are now history, having been replaced by CAxHost and CWebCtx. I have also have modified the examples and templates.

I think that it is time to leave the release candidate versions and post the first version of the WinFBX framework. WinFBX means Windows FreeBasic Extensions and it has been chosen to highlight its ties with the WinFBE editor. It can be used with other editors, but WinFBE makes its use easier.

[Paul Squires]

That's great news Jose! Congratulations on making it to Version 1, although with everything that's in this package it feels more like version 10! 

[ganlinlao]

wow , Jose,thank you very much!

hi, jose
Error in compiling example mothviews. There is an error in axhost.inc

[José Roca]

In fact it is a bug in the version 1.05 of the compiler. You can download version 1.06 at http://users.freebasic-portal.de/stw/builds/ or change pAxHost->m_bInPlaceActive = FALSE to CLNG(pAxHost->m_bInPlaceActive) = FALSE.

The other error is caused by a change in Put from a function to a property. Use this code:

Please note that these examples are for testing purposes and use the a registration free technique (I don't have any of them registered). If they are registered and licensed, you can use the constructor that accepts a ProgID. As with my previous OLE containers, some will work a some won't. VB6 used the form as an OLE container and implemented interfaces (some not standard) to build complex controls that contain other controls, and even arrays of controls. These are outside the purpose of my modest OLE container. I wanted to use ATL.DLL, but it works very badly.

[José Roca]

CDispInvoke.inc

I have changed Put and PutRef to a properties, but as FreeBasic doesn't accept more than a parameter in properties, I also have added the Set and SetRef functions with up to two index parameters (I think that two are enough; we could add more if needed).

But whereas Put and PutRef will allow this syntax:

pdisp.Put ("property name") = value

being a function, with Set and SetRef you will have to use

pdisp.Set ("property name", index[es], value)

[José Roca]

I have added another overloaded PutRef property. Only when testing you find the convenience of additions to ease its use.

Preparing the test for the Microsoft Hierarchical Control (see below) I needed it to set a pointer to the data source.

[José Roca]

Two of the Microsoft grid controls, the Flex Grid and the Hierarchical Flex Grid work well with my OLE container, and because they use twips, they're DPI aware. It is a pity that they are only 32 bit. Maybe I will write classes to ease its use and add events.

I thik that CDispInvoke has become easier to use than DispHelper, and without having to use a third party C++ DLL.

hi，jose
I downloaded and used the fbc1.0.6 compiler and downloaded your latest idispinvoke.inc.
Using the latest example code from above. In the mothview example, there is still an error.
Code:
DIM pdisp AS CDispInvoke = pHost.OcxDispObj
   pdisp.Put ("Year", 2017)
   pdisp.Put ("Month", 12)
   pdisp.Put ("Day", 25)
Will show the same type of mismatch error.

pdisp.Put ("Year", cVar (2017))

This will not be a problem.

I really like idispatch.put ("") = value like this style, thank you very much. I am very  looking forward to your ways to provide easier-to-handle "events".

[José Roca]

Works fine here. Maybe you're using an outdated CVAR.inc.

[Eigil Dingsor]

Now it is a matter of seeing if the task can be simplified, if we can use a Free Basic class instead of a plain virtual table, etc.

I'm only interested in low-level COM servers. I don't plan to get involved in the nasty business of creating OCXs, type libraries, etc.

Please note that I'm not using DllMain or LibMain in the DLL because apparently it does not work, so I'm using the constructor and destructor of the module instead.

Very late comment to this post, but I've started to look at Jose's conversion of "COM in plain  C" in conjunction with FB's EXTENDS and OBJECT syntax. Thank you!
It is possible to compile a dll with a Libmain that performs some code at startup. You have to define your own libmain and tell the compiler and linker to use that as the entrypoint function.

example

Code Select Expand

'Using dllmain insted of constructor   code aboce.
'compile with -e switch .Forcing entry function


'/************************** DllMain() **************************
' * Called by the Windows OS when this DLL is loaded or unloaded.
' */

Function  DllMain alias "DLLENTRY"(instance as HINSTANCE ,fdwReason as  DWORD , lpvReserved as LPVOID )  as long

select case fdwReason

case DLL_PROCESS_ATTACH

'// Clear static counts
OutstandingObjects = 0
         LockCount = 0

'// Initialize my IClassFactory with the pointer to its VTable

          MyIClassFactoryObj.lpVtbl = @MyClassFactoryVTbl
'// We don't need to do any thread initialization
DisableThreadLibraryCalls(instance)

end select

return 1
end function

To compile a DLL add this to the build configuration(WinFBE)
-s gui -dll -export -Wl -e_DLLENTRY
