I have some problem in writing An ATL COM Simple Server. When i try to make a new project i notice that some files where the main code must be are not created.
For example i write a project with name FirstCom, and i don't have FirstCom.h, and in FirstCom.cpp i have only this:
And that's why i think i have error, that my servers isn't registred(smth like this). I haveVisual Studio Net 2002 and WTL installed. Can it be the problem??? How to uninstall in that case WTL??? Or What To Do???Thanks.

That all looks like a standard VS.NET ATL app wizard generated code (using attributes)
You certainly shouldn't have a FirstCom.h, because all the code is added into the stdafx.h for the DLL.
After you've generated the dll framework, you need to add a new ATL Simple Object class. This is the COM object, for which you should have a cpp and h file for.
Have you added a simple object or did you just run the wizard?

Yes, i'd added the simple object.
By the way, i've seen an example of minimal com server in MSDN and the had the normall code in .h and .cpp files.
So i still don't know what is the problemm.
Thanks

When you generated your project, you left the wizard attribute option set. This is why you don't see any code. It is all done by the new attribute stuff (which I still don't fully understand myself).
If you want to see the C++ code for your COM server, you will have to regenerate your project and make sure you to turn the Attribute checkbox off.

Do you have admin privileges on that machine?
Have you tried manually registering the DLL from the command prompt
regsvr32 mydll.dll

Thank you very much for "regsvr32" but i want to say something about it .
For the first - i couldn't find it on my computer . So i had to copy it from another .
And about visual studio NET - i still don't know why it didn't register itself this dll.
Thanks again.

hi all
after succeeding in creating tabbed pages in my application. I realised to my greatest dismay that i cant display e combo boxes (Cant display the page after adding >25 combo boxes) I really dn't understand the situation. where did i go wrong?
everything works perfectly fine with <25 boxes......
hope someone can help me here!

Do you get an error message or an ASSERT?
How are the combo-boxes created? Are they done via the resource editor or via a call to Create?
Your best bet is to step into the page creation code and find out the exact line the problem occurs.

oh... there's mo error when compiling. Its when i execute the program, the tabbed pages don't display correctly. I really don't know why. I created the combo boxes using the resource editor.
Page creation code? Do you mean the File View?
Thanks =)

I am working on a dialog type project using the base class CFormView and SDI and I am also using another with MDI. Both involve using edit boxes and basic variables such as INT, CString, etc. also will involve simple math, my problem is in the serialization of the data. How do you serialize the data when using CObject as a class, one of my variables is m_sName, is this wrong for serializing or not, yes I am a newbie to C++ and I have lots of books on serializing and they confuse the heck out of me. I have used Cobol and can do this in Cobol but C++ is hard for me to learn, maybe you can suggest some web sites with examples I can learn from. I realize you could write a book explaining serializing but I could use some general guidelines. Thanks for your help and I won't lose any more hair over the frustration.

Hi There,
I want to know how I can support multiple ‘FormViews’ by having a single ‘Document’ class in my ‘SDI’ Application. The class which ‘MFC Wizard’ makes it for us supports the document. But the additional ‘FormViews’ which I put in doesn’t have access to the ‘Documents’ variables.
The code which I tried my self are as follows:
These are the additional or the ‘Nth’ classes
Class CSection : public CFormView
{
…
};
void CSection:: OnInitUpdate(void)
{
CMyDoc* pDoc = (CMyDoc*) GetDocument();
This code works in an SDI application in which classes are derived from ‘CRecordView’.
}
void CCourse:: OnInitUpdate(void)
{
CMyDoc* pDoc = reinterpret_cast<cmydoc*> (GetDocument());
}

I got a problem here
Is it possible to programme using C++ without asking the user to key in the values but rather the programme can itself search for values from a list of data output from another programme
Thank for any ideas

But how do I go about doing it?

You might pipe the file into the standard input stream of your program (which you would treat similar to how you do keyed user input).
You might connect to a database or read some files located in the filesystem.
You might make a web-services call or use another RPC to communicate with a program running elsewhere.
What exactly are you trying to achieve?

Actually I am doing a project on face detection
Now i have got the output coordinates of facial features but there are too many of them and i need only a few of them to do analysis so as to achieve face expression detection.
So will the coordinates selected, like x,y (12,23)for neutral expression I want to compare will another x,y (45,76). If if it satisfy the happy criteria, then output will be happy
So how should I link two programmes together?
The first programme output a list of coordinates while the want I am doing will get some valuse and output the expression
Thank for your reply and i do hope you will help me

Now, I want to get a pixel color from picture.jpg at coordinates (50,80)
How could I do this?
Thanks a lot

ATL has a CImage class which lets you load an image from file and do whatever you want with it...
Just check out the CImage class in MSDN to get you on the road.
Don't think you are, know you are...
