I think that you need this....
CString m_strProperty = _T("");
STDMETHODIMP CCPerson::get_Property(BSTR *pVal)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
// TODO: Add your implementation code here
::SysFreeString(*pVal);
*pVal = m_strProperty.AllocSysString();
return S_OK;
}
STDMETHODIMP CCPerson::put_Property(BSTR newVal)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
// TODO: Add your implementation code here
m_strProperty = newVal;
return S_OK;
}
Cheers.

This isn't a COM object as much as it is an OCX. The Get/Set functions were inserted by ClassWizard, and they accept/return VARIANT's. I'm using the _variant_t wrapper class because it's easier to work with (or so I thought).
|
|
|
|
|
in the code you show that you are using VARIANT return type for your property;
may be the vb ide gets an ip-address wrong as anumber (with to many dots in it).
Try using BSTR (*) ? as return type to get a real vb string, (or may be you only
need to set vaResult.vt to the right variant type constant)

This is a question on system programming (like Windows API, hardware programming, etc).
How to read a disk directly in Windows (under Win32)? I need the following equivalent of DOS functions:
INT 25h/26h -- absolute disk read/write (i.e. reading logical disk sector)
INT 13h -- physical disk sector read/write
I need the equivalence of INT 25/26 *very badly*. Especially the READ function. This should be something trivial. If you know an URL containing this info, I would appreciate it.
Assume I will write the program under generic C++ program (GNU C++). But if you know something, you can assume other things if you want, but *I don't* have Delphi, MSVC, etc....  Please... I need someone help me find the right reference.
Thanks,
Wirawan

Just curious: why do you need this functionality?

I have a list box in my project and i need the user to be abel to delete an object from the listbox but you can only delete a strings if you know the number place where the string is in in the box. How can i have the project find the number sting when the string is clicked?

GetCurSel returns the current selection index. So you go m_List.DeleteString(m_List.GetCurSel());

If your going to make this like you are why don't you do it in QBASIC. It would be so simple you could finish it in a few minutes. If you want I can help you do it in QBASIC, E-MAIL me @ rcdude10tc3@aol.com, c ya

1) You haven't told us what you want help for.
2) This looks like a school homework assignment. I have a real problem finishing someone's homework for them. If this is an incorrect assumption, I'll apologize now, but I don't want to see CodeProject become a haven for folks too lazy to learn how to do stuff on their own (when it's necessary for them to do so).

Well, don't you think asking specific questions would get you a specific answer a lot freakin faster? If you cop an attitude, you'll get attitude back.
[attitude]
Go somewhere else if you want someone to finish your homework assignment for you. I have a idea, go ask your instructor.
[/attitude]
yawn...

This is clearly a homework request. Nobody would write a new app in the 21st century that requires the Enter key to be pressed to step through a list of entries.

A hint for posting code on CP forums.
this method preserves all the < and > brackets, and all the code in between them.
1.) In VC IDE highlight the code you wish to post.
2.) copy the code to the clipboard (menu : Edit | Copy, Keyboard Ctrl + c)
3.) start Microsoft FrontPage Express
4.) in MS FPX, paste your code (menu : Edit | Paste, keyboard Ctrl + v)
5.) edit your message in MS FPX
6.) select menu item View | HTML, a window will popup containing the HTML text of your message.
7.) highlight all the text between the lines <body bgcolor="FFFFFF"> and </body>. Do not include these lines. This is your message.
8.) press ctrl + c (copy to the clipboard)
9.) in Code Project's submission edit box, press ctrl + v
now your submitted code will contain all the < and > brackets. it just makes it a lot easier for others to now what your actual code is, what header files are included, ect.
and please use the Preview button to make sure the code you submit is the code you want to submit.

I have a small problem , Please help me !!!
This is my code:
-----------------------------------------
void CTestDlg::OnOK()
{
// TODO: Add extra validation here
m_edit1 = "22222222222"; //CString תיבת טקסט מסוג
UpdateData(false);
Sleep(3000);
m_edit1 = "1111111111";
UpdateData(false);
//CDialog::OnOK();
}
--------------------------------------
Why the first message ("222222222") dont apear in the edit box when this program runs ???

Because your program's thread is suspended in the Sleep() call. Windows don't just magically repaint, your thread and message pump have to be running.

Sleep doesn't allow Windows messages to get through. You need to use something like a timer or a message pump function.

Thank you very much on your answer.
Can you show me example how to use in timer ???
miri
|
|
|
|

You are going to need to capture the WM_TIMER message, in this function you perform whatever actions you require to happen at a set interval. The message is started by a call to SetTimer and finished with a call to KillTimer.
SetTimer(1, 100, NULL);
KillTimer(1);
void CMyDlg::OnTimer(UINT nIDEvent)
{
CDialog::OnTimer(nIDEvent);
}

How can I to change a static picture(bitmap) from disible to visible and from visible to disible in the code(wich metod?) ???

You just call the ShowWindow method of the corresponding CWnd, with parameter SW_SHOW or SW_HIDE.
The CWnd* can be retrieved by GetDlgItem(ID) or you subclass the ctrl with the classwizard.
Pseudocode is code to demonstrate a concept, not designed to be run.
Like certain Microsoft software.

thank you!
Can you show me example ?
I need to show a picture that defined as CStatic(bitmap)
and after a few minutes to hide it .
How doing it ???
