You know C right? You make a lot of thing in the console. But if you want to create a windows button ? a textbox ?and the things that targets MS Windows. So we need a visual API right? It's called Win32API. 32 is to say the API is for 32 bit Windows OS. It's fully "C" based.
Now C++, why do you need C++ when you have C?
C is all function oriented. When your program get into 1000s of lines . It becomes a hell. C++ has a lot of features that complies to OOD(Object Oriented design). It makes things much easier to control when projects expand out of boundary. So why not Use C++ instead of using "C" for visual programing with the Win32 API. Here comes MFC  , It wraps all your raw win 32 Apis and gives everyting as classes. You create an Object to that class, and play with it easily. MFC is the Object Oriented framework in C++.
Win32,MFC,ATL,WTL etc comes under VC++. VC is the compiler provided by Microsoft for creating these programs. So never say MFC or VC++, may be you can say.. Win32 or MFC.

how do i retain items in the list control so that even when i close the application, the items would still be availiable in the list control.
|
|
|
|
|
Save it to a file. At the time of retrieval just read from the file
Somethings seem HARD to do, until we know how to do them.

Read the items from the list control. When you are closing your application/relevant dialog write the contents of the list to a file.
Use CFile, CStdioFile, fread() / fwrite() to put/get the data to/from the file and put it in the corresponding rows/columns of the list control when you are calling the list control dialog to display again

So have you not studied up on file I/O? That's very basic stuff, that should be mastered before advancing on to more difficult topics.

if you have for example a listbox
(1) Create a file with CFile or CStdioFile
(2)read items in the loop from listbox m_litsbox.GetText(i,str);
(4)write to file
(3) close file
And read MSDN and a good book

No, hcd is correct.. I use CImage.load(...) and then I have problem with close - is not called any error, simply application is not close. I read that is some problem when is CImage in ActiveX - it is true?
|
|

|
|
if you read that some problem is with CImage in Activex why you use form it in ActiveX

Hello!
I want to create an WindowsFormApplication in VC++.NET (MSVS 2005)
which uses a TabControl.
In my Application the user should be able to create or remove tabPages,
so i`d like to have the Pages always fill the entire width of the TabControl!
I already tried with FillToRight, but that doesn`t worked...
So my Question is, why not? does FillToRight works only if there is a second row (mulitline true)? Or am i simple too stupid? I work on that for the last 4 hours!!!
Is there another way to set the Size of these TabPage "Heads" or do i have to write my own TabControl Class? (like http://www.codeproject.com/cs/miscctrl/flattabcontrol.asp)?
Pls can anyone help me?
Thx

Hi,
I am using OFN "Open" and "Save as" file dialogs. It appears in the corner of the screen. How can i bring it to the centre. As we are not creating it what can be the solution without customizing it.
Thanks in Advance,

Just use a hook procedure. In that procedure, respond to the WM_INITDIALOG message and center the window accordingly.

IMHO, you have to customize that!
