Activex coding

Hello,
Is it possible with PureBasic to build an Activex ?
Something like the flash plugin, callable from a HTML page via the <OBJECT> tag? No, I don't want to make a Flash clone :wink:
In other words, I'd like to make something like a Java applet, but coded in purebasic...

Hi,

maybe this helps you ...

Best wishes, benny!

Well, It's useful for controlling other applications (I did it a lot with a VB project at work) but not for building your own activex...

creating activeX from the ground (ASM) is a very complex thing .

Here are some very good infos using masm : http://ourworld.compuserve.com/homepage ... orld/a.htm
or here:
http://www.japheth.de/

It is not impossible, but very tricky to do such with PB.
i prefer VB or VC++ to create such.All the needed ActiveX-Ground-stuff is already included and you can create classes very easy . Also delphi and other c++ compiler should do the job.Do not know for other languages.

Any luck with this Blade? Building an ActiveX control w/ Vb or VC totally goes against what PB stands for, no? horrible runtime libraries.. I am also interested in making either ActiveX controls or ActiveX DLLs (preferred), but have made almost no headway on this..

No, I didn't even tried. I just posted that question because it's a project I'd like to start when I'll buy PB.

I'm still not sure that it can be done easily with PB too!

I hoped the the new 3.80 features (interfaces etc) could help doing this, but seeing the (few) examples it looks complex as if you had to do it using C. I hoped that PB could help somehow with this stuf... :(

I wrote a "XIncludeFile" generator in PureBasic, that generates an IncludeFile with all the CLSID, IID and VTable and Dispatch Interfaces for a selected control. After starting the program, it shows all the registered controls. By clicking a control, it fills a listview with the enums, constants, interfaces, dispinterfaces and so on for that control. By clicking a (disp)interface it fills the bottom listview with the details. That will be a custom Vtable interface, a Dispatch Interface or a Enumeration (for building your clientsite eventsink) depending on the radio buttons. You will find the Code below.

Code: Select all

Same here... WinXPhomeSP1

Also it's not possible to compile controls.pb, GUID structure is missing.

I developed the program on Win 98 and did not test it on WIN XP.

About the error.

In the top left listview's the controls in the registry are shown. If you click one of them, the program searches for the registered typelib of the control. The typelib contains all the information about the control and without it, it is impossible to retrieve the data necessary for generating the XIncludeFile.

Greetings

I added some code that will ask for the file that contains the typelibrary (*.tlb; *.olb, *.dll, *.exe; *.ocx) if the type library is not registered. In that case you have to know the file name.
