I want to create CBitmapButton in a dialog with CButton::Create(), but for some reason the button is not visible when I run the app.
I put the following code in CDialog::OnInitDialog()
<br />
VERIFY(m_whiteBtn2.Create("", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON | BS_OWNERDRAW, CRect(200, 100,85,48), this, IDC_WHITE_BUTTON2));<br />
<br />
VERIFY(m_whiteBtn2.LoadBitmaps(IDB_WHITE_BUTTONU, IDB_WHITE_BUTTOND));<br />
Does anyone know what might be the problem?

You might want to try BS_BITMAP...

I've already made it work by using AutoLoad(), but I'm having problems with using CButton::Create().

In case you don't get your code working, see this article.

After calling the button's Create(...) method, you must call its ShowWindow(SW_SHOW); method to actually show the window.

hello again,
once an application has been compiled, you can pretty much delete the source code and it will work fine.
how about if i need to get the code for a certain application back - i deleted it by accident.
how can i get the code behind a compiled working application.
thanks for you help guys

Source Control. 
Or, perish the thought, maybe even Back Ups.
But in your case, I suspect these aren't going to be suitable.

I'm not sure about other languages apart from C++, but compilation is a one way process. There is no undo process.
There are programs that allow you to build messy assembly language interpretation of a given EXE file, but the 'original' source code used to build the program is unobtainable.
Why in god's name would anyone want to build an app, then delete the source code anyway, especially if future fixes may be necessary?

I'm not a Mallory personality then. I still have source listings and floppies from my first excursions into programming (Z80 assember and DBAS12 BASIC from an RML-380Z microcomputer), as well as everything in between. I learned very quickly about 'backup' and source control, which has saved my behind on a couple of occasions.

no way to get the source code back in C/C++, because the compiler performs some optimisations on the code.
i remember that Borland C++ 3 could do so with a debug-Built project, but i don't think it works with a binary code compiled by Visual C++. And even less in Release Mode...

Dear all,
I use several true color icons for my main menu. However, I didn't know how to add my customized disabled icons to menu item so that the program can use my disabled icons instead of automatically change its color in its own way. By other words, how can I handle the icons in front of each menu item in popular circumstances as normal and disabled. Thanks so much.
BRs.

Hello.
I have an understanding problem with saving complete classes to an binary file.
//First example:
<br />
Class myAnimal<br />
{<br />
int age;<br />
int legs;<br />
...<br />
}<br />
...<br />
myAnimal Bear(2, 4);<br />
fout.write((char*) Bear, sizeof Bear);<br />
fout.close();<br />
<br />
...<br />
fin.read((char*)&Bear, sizeof Bear);<br />
every thing is fine
// Second example:
<br />
Class myAnimal<br />
{<br />
int age;<br />
int legs;<br />
...<br />
}<br />
Class myBird<br />
{<br />
int age;<br />
int legs;<br />
...<br />
}<br />
...<br />
myAnimal Bear(2, 4);<br />
fout.write((char*) Bear, sizeof Bear);<br />
myBird Tweety(6, 2);<br />
fout.write((char*) Tweety, sizeof Tweety);<br />
fout.close();<br />
<br />
how do I know which class is now read from the file?!?!?!
// Third example:
<br />
Class myAnimal<br />
{<br />
int age;<br />
int legs;<br />
...<br />
}<br />
class Cage<br />
{<br />
myAnimal Bears[10];<br />
}<br />
<br />
Cage Bearcage();<br />
fout.write((char*) Bearcage, sizeof Bearcage);<br />
fout.close();<br />
and will be every single Bear be stored, or do I have to do it for each single Bear? How do I load these Bears? Every single one?
Sorry for my bad english, but I hope you understand my problem. Thank for help.

would be one way, but it is a bit clunky. I'd recommend serialization, but without knowing more about what you are doing, that's a tentative recommendation.

Dont you need MFC for Serialization?
This little program has to be platform independant.
What do you need to know to help me? This is not a special project, I am only learning. I haved programmed for more than 5 years MFC. But soon I will work for project, that is platform independant, so I try to learn such topics and their problems before.
Serialization with MFC is easy, but how do I realize ist without MFC?
Thanks for help.

Yes (it might be possible, albeit more difficult, outside the scope of MFC, but I've never tried). Your initial post did not mention platform independence, which is why I suggested serialization.

Oh, i am sorry, that I did not mentioned. 
But I have thought, that nobody will use fin and so on with MFC... 
Thanks for help.
