A Message Only Window is typically a window that you create that is kept invisible and does not receive any user input. Its sole purpose is to receive window messages.
You can use the CreateWindow(...) function to create just about any window that you would ever need.
BTW - I think that there is a special style available in later versions of the Win32 SDK for message-only windows, but I cannot find it now.
Peace!

I need some help interpreting the Spy++ listing of window items...
In the listing of windows, handle values (in HEX), short description, ... all listing in a tree view, is the ordering within a group meaningful?
Let me clarify my question:
I am debugging a huge GUI application and the past developer created most of the buttons on the GUI dynamically (on the fly) using bitmap images and the CButton::CREATE() method(s).
I am using Spy++ to identify some buttons.
If I am looking at the listing of window handles in Spy++, does the order listed reflect the order in which the buttons were created?
I am trying to find a run-away button that is in a place it shouldn't be on the GUI and not controlled (hidden/enabled) when it should be.
Thanks!

I am working on a program that takes an input of 2 numbers from the user, checks the primality, generates a public and private keys, validates those keys by encrypting text entered by the user and decrypting text entered by the user. Can anyone help me with some code for this project?
Thanks!

Hi
I am looking at someone elses project and source code and seeing something I need explaining!
There is a STATIC member function declared in a class.
eg.
class myClass
{
static void myFunction();
}
Then it is called using the scope resolution opperator.
myClass::myFunction()
but it is being called from another source file in the project!
I can't see any reason why it is aloud to do this. In fact I have added my own class and function
looking exactly the same and it gives me LNK 2019 error.
Any Ideas what I am missing.
Thanks in advance for your time.

If it wasn't allowed, then all our source code would
have to be in one file. Thankfully we have a linker
to link separate compiled code modules

To do its job, the linker needs to know where to find
the code to link to. What's the complete error you're getting?

Nope.

you're saying this as if such construction never exists... but I'm sure it is !
for example, the following is perfectly valid : "If I were you, I wouldn't do that"...

Mark, wait.
I didn't say all I write is gramatically correct; I make mistakes sometimes.
BUT, isn't the construction I just asked you in this thread valid ?

I'm just goofin with you here, of course.

I see it now sorry
Yeah you are right I think. The more I say both versions, yours sounds better.
And using "was" implies past tense which seems silly.

And you're right [^]. Anyway it looks like 'wish ' is needed in the sentence.

Hi
I was in the understanding that if you declare a static function it can only be called from the source file where it is declared.
Am I missing something??
The error says "unresolved external symbol"
the call to the function is in file1.cpp where I have:
myClass::myFunction(variable1, variable2);
In myClass.h I have:
class myClass
{
static void myFunction
}
and in myClass.cpp I have the function definition:
myClass::myFunction()
{
//function definition
}
I can't call myFunction from file1.cpp
As you can tell I am a novice programmer and in desperate need of explanation

Yes That would make calling any external functions
impossible.
steph5 wrote: I can't call myFunction from file1.cpp
The linker can't find myClass.obj.
Is myClass.cpp not part of the project?

That's true.

Yes: in
steph5 wrote: class myClass

is not an ordinary (i.e. C-style ) static function, is a static method (i.e is a member of the class even if you don't need an instance of the class to call it).

Huh? I call static methods that aren't in the same
