Can the icon size of the icon to be displayed on a CButton be set
|
|
|
|
|
|
I believe button icons are displayed centered on the button and if the icon is bigger than the
face of the button it is clipped.
If resizing the button so the icon fits isn't acceptable then you'd need to resize the icon first
before setting it to the button.

are there cases where we should write our own copy constructor and assignment operator overloading in the class?
Thank you.

Please refer this[^].
When you have atleast a single member varibale as a pointer variable.

If your class have member variables that are pointers and/or allocate memory, you have to write a copy constructor and assignment operator. Probably even a "==" operator.
If you don't, the compiler will create those for you and they won't behave the way you want them to. It creates shallow copies, performs member wise comparison and so forth.
You can assume that you should write a copy constructor for each class you develop.

Yes. The first example that comes to my mind is for smart pointers for example. Another example would be for a string class (you need in fact to copy the contents of the char pointer, not just the char pointer itself).

hi

my application is meant to work for both windows mobile and desktop pc.
thanks.

These two platforms run different versions of Windows and are not binary-compatible. In other words, you need two different .exe files, each compiled and linked for the appropriate OS. They use the same processors but the OS runtime DLLs are different and different APIs are supported.

i know that i'll be getting two different exe's. but i need the #ifdef for compiling under x86 platform. for windows mobile i am using #ifdef POCKETPC2003_UI_MODEL.

Sorry, couldn't tell how much you knew from the initial question. If you're compiling the code with any Microsoft tool, it assumes the x86 class of processors unless otherwise specified. I'm going to assume you're not asking about the define for x86 compilation but rather the define for regular desktop windows compilation versus mobile compilation. It's been a while, but last time I had a GUI that was written to compile under both VS for regular desktop and eVC for handheld (same source code files with a unique solution / workspace for each IDE), I used the handheld desktop define as the key for both situations. Stuff that was handheld only was #ifdef <handheld define> and desktop only stuff was #ifndef <handheld define>.
My memory may be faulty, but you could also try _WIN32 versus _WIN32_WINCE. I don't have eVC loaded to see if the _WIN32_WINCE is defined for all the different system selections.
Hope this answers your question, since I'm not sure exactly what you need.

Is it possible to learn MFC without learning or without going through Win32. 
|
|
|
|
|
IMHO
MFC is a library that allow you to do a lot of things, but not all of them, yes, you can use MFC, but soon you'll be using win32 instructions and, who knows ATL or any other library that would allow you to do different things that you'll need...
hope this helps.

You will either pick up a lot of Win32 in the process or not learn MFC at all.
MFC ist for the most part just a C++ layer around the Win32-C API.
Failure is not an option - it's built right in.

Mostly likely learning C++ without going through C.

MFC is nothing but the C++ wraper classes written over WIN 32. For example in SDK we have HWND, here in MFC we have a class CWnd. There are ready made classes and macros available for you.

Paresh.

Yes.
BUT you will have to stay within the constraints of MFC structure and limitations.
if you want to do UI things that are not directly supported by MFC, then you will have to learn a little bit of Win32.

Yes but IMO only if you never want to write your own code.
If you will only be using copied code you'd be ok.
In other words, you need to understand Windows programming to understand what MFC is doing.

I need to call ActiveX function from a thread so while it elaborate my app can go on.
I made my CMyThread class derived from CWinThread class, in which I and create the thread in my app when I need to call the ActiveX functions.
I have some problem:
1. In code when I need to create the Thread attach this code:
CMyThread * thread = AfxBeginThread(RUNTIME_CLASS(C4Thread));
but at compile-time it said "It's impossible to convert from 'CWinThread *' to 'CMyThread *'.
WHY this?
2. In which method of my CMyThread class I must put the code to peform (the call to the ActiveX functions) or I need to implement a new function? In thi case how?
Thanks a lot.
