I tried that at first. It doesn't link. FYI, I'm using VC 6.0 (at work) unfortunately.

it is unlikely that it is a link time error. What error do you get exactly?
Most likely, you get a compile time error, and need to define both WINVER and _WIN32_WINNT[^] accordingly before including windows.h

No... it's a linker error.
gditest.obj : error LNK2001: unresolved external symbol _GetGuiResources
Debug/gditest.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
I get this if I try to use the function with only including windows.h or winuser.h and linking to the user32.lib.

How are you trying to call GetGuiResources()?

So I used LoadLibrary to load the dll and I used GetProcAddress to get the address of the function. But I can't figure out how to call the function.
HMODULE myDll = LoadLibrary("user32.dll");
void* myFunc = GetProcAddress(myDll, "GetGuiResources");
You are wanting GetCurrentProcess(), yet you are loading GetGuiResources(). Why?

Because I typed that wrong. :-p I want to use the GetGuiResources function.

Hi ,
I Have a CArray in a FileMapping in a DLL and Iam Adding items from an process to the CArray. Its throwing error .Can CArray be present in FileMapping?
|
|
|
|

No, it cannot.
CArray allocates memory to store the actual data dynamically from the heap, so the actual data is not included in the file mapping.
To put an array into a file mapping is not quite easy for multiple reasons.
Generally, classes cannot be used directly in a file mapping, unless they are specifically designed for this, or they meet very restrictive requirements. Also, the elements of your array msut meet the same requirements.
I am not aware of any implementation that is ready-to-use.
If both sides can agree on a fixed or maximum size of the array, it is probably not very complicated to use a shared size, and a pointer to the data (wrapped in a nice class  )

How Long Does It Take For A Beginner To Become Like You? I Really Want To Know...

a lifetime?!
For me, it's about 20 years that I first touched a computer. But I also wasted a lot of time with games I had many obstacles that in hindsight helped me a lot.
But seriously, to become a "useful developer", there is something that takes time, and can't be cut short.
It starts with having experience with a lot of different things - be it languages, protocols, concepts, ideas, paradigms, tools. Later, this allows you to move smoothly between layers of abstraction. At one point, your product, your software becomes independent of all these ways to communicate - with peers or compilers.
Only recently I achieved the point where I move between programming languages without effort, I don't really know how to express that, but let me try:
Software is a thought. Programming means giving this thought a clear shape, turning a vague cloud of smoke into a crastyl with asharply defined corners. OOP, UML, C++, C#, Scheme, Assembly, TCP/IP, German are all languages to express this thought, to explain this thought to your compiler, your collegue, or your PC. But the concious part of your mind isn't thinking how to express a certain thought in a certain language, but it is busy shapingthe thought itself.
Sounds more esoteric than I'd want it to be. And there are lots of programming things I am terribly bad at (that's not a weak attempt at modesty, but a provable fact).
Tips? Learn to read - read a lot, read fast. That's the most valuable skill you can actually train.

If I declare a CEdit dynamically in my dialog file and try to connect the resource id of editbox to it via
DDX_Control(IDC_EDIT_BOX, *pEdit);
The program asserts. It works fine if I create a CEdit object on stack and pass it.
Why is it that DoDataExchange doesnt work as expected with dynamically allocated variables ? I thought I knew Intermediate level MFC before this one stumped me 
Thanks

Are you creating the CEdit object and calling Create() before or after calling CDialog::OnInitDialog()?

No, what's the need of that if I am doing DDX_Control?

It's required. Now, where is the call to CDialog::OnInitDialog() in relation to where the CEdit object is created and its Create() method called?

I don't think so david. I am pretty sure I don't need an explicit create call in my oninitdialog if I am linking the editbox with the dialog with DDX_Control call.
As it turned out, it was an issue with the resource ID.Thanks for the advice though.
Regards

Correct. But the CEdit object must be created before CDialog::OnInitDialog() is called. Otherwise, DDX_Control() will throw an exception.

Do you want to make dynamic editbox and use of their events?

So I am using the solution Explorer and I link two projects together. The question I want to ask is how do I run an object that is created from my second project on my first project? Is there any easy way to do that using include? I tried looking through the microsoft library on Project Dependencies but I am still confused. Thanks

As in I have two projects different projects in MFC in a solution. I want to call the dialog created by the second project in my first project.
|
|
|
|
|
But why you want to run a dialog of a project on other project,do you have any idea?

The answer depends on what kind of projects you are using. It's easiest if you are using an object in a static library. Then you need to use the include files from the library project and link the library into the calling project. With other kinds of projects, it becomes more complicated. Could you explain in more detail?
