First let me tell what I must do. I have been asked to do one application that can program many kinds of hardware devices.
Some of them I know, others I do not. This mean that my application must be prepared for new devices.
Furthermore, the programming software for each device should be available for other applications.
Ok, after this I began studying controls (activeX controls).
It seems to me that if I could make each programming software one activex then the problem of using in other environments
will be solved. Further, if a new device appears then I will just have to do another activeX.
Of course, the activeX interfaces would have to be the same for everybody.
Here is my big problem. How can I do my application to accept addons whithout the .h files!?!
Ok, my question is a bit weird but I am new to this world.
I have been able to make some simpler activex controls. But I have many problems in using them. This is
because my application can only meet them on runtime.
I think that what I want is something like the MMC functionality. That is we can add things on runtime.
So, lets suppose that I have the following CString OCXFile. This has been filled by one user action to lets say
Lets suppose also that each of my addons will have the methode AboutBox.
How can I call this method by simpling knowing the name of the ocxFile!?
Maybe I am wrong but I am thinking like C++. That Is I Have on class purely virtual with the names of the methods.
My addons are all derived from this class. On creation of the addon is the selection of it.
From what I have read one way is to insert the activex in a dialog box.
But for me this is impossible because the application must stablish the contact on run.
Every comments and solutions will be mostly appreciated.
I am giving a significant amount of points because I am looking for good comments to guide me and not just lines
My thanks for reading this.
