Can you use an ocx in a dll?

I have an OCX that I can use with a form to put an object and then access methods and properties of the object. Works fine in that type of environment.

However I need to make a web application where I am using some of the methods and I need the end product to be a dll. Is there a way to have a dll that has no form, able to use the OCX tool?

If u will use this ocx file,U can create the object and call the function in the ocx..

design your program on paper and decide which properties and methods you will need to access of your ocx. Then, declare a new variable of your ocx type and write properties in your dll to handle the properties and methods of the ocx you need to access. Just make sure that a copy of the ocx is included on the server.

A question though... Why do you need the end result to be a dll?

How do I create a variable to my OCX type? For something I have referenced I can just do a: Private myRef As thereference, but an OCX isnt in the reference list, even though I have added it as a component. Is there a way I can reference my OCX?

Sorry its been awhile since I have worked with VB, very rusty. As for why a dll, what are my other options? I plan to reference it via a com object with PHP.

Thanks,

One more question. What OCX are you using? I'm not sure about PHP...Some Ocx's are web ready in ASP.NET... sometimes you can find the classID in the registry and add a new object of that classid.

Its an older proprietary thing, def. from before .Net becoming common.

Which the ocx file do u lost in the project??The vb will show the lost reference when compile the program!After Find it,u will add it to your reference list!!

Ok.. I've included an .ocx directly into some HTML that I have built. This is a very, very simple example of how to get an ocx into a web page...


This may or may not show up on your box, depending on whether you have the ocx installed or not. It's a control called "Coolbar" that I randomly selected from the registry. I typed in "regedit" from run on the start menu, and navigated to "HKEY_Classes_Root -> Com_Ctl.3 -> ClsID" to get the class ID for the object I wanted to insert. You might try doing it this way rather than trying to use a .dll wrapper. Otherwise, i would reccommend using VB.NET to write your dll as you can use an imports statement to get the classes into your project.

Isnt an OCX file just that, a file? How do you register an OCX so it will show up in the registery and have a classid? With a dll I use regsvr32, I didnt think you could use that with an OCX file?

Having a hard time following you cleverpig. geocode.ocx is the ocx control, I can load it as a control in VB and it lets me draw a control on a form. I can then access the properties of that control, however in the dll I am making I dont have a form, only a class module so I wasnt sure how to connect the two together.

nope.. an OCX is essentially executable code, it is basically an activex dll with a visual control wrapped around it. You can register it through the same procedure as a regular dll, unless it has a programming error that will not allow Windows to find the entry point

Just for clarification, I found this on This Site

Thanks Fisherman. One last question, how browser compatible is the classid property with <object>?

Thanks again,

Cul

well, I'm not exactly sure what it is that you're asking. If you have the classid on a registered ocx, then you should be able to access it in the way that I posted before. If you're asking whether it is cross compatible with other browsers... then it should be - object is just an HTML spec keyword. A word of advice, to discover your class hierarchy (functions and properties inside your ocx), use the dependency walker to view interior methods.

ok thanks!
