Yes, but it will return you a CWinApp pointer, not a CtheApp pointer. That's why it must be cast to the appropriate type.

Exactly.
AfxGetApp() Returns a CWinApp class pointer. If you want to reference your specific class, you have to cast the returned pointer to your application class. This will allow you to access your member functions. The olden way of casting used to be of the form:
CMyClass* pClass = (CMyClass*)(ParentClass);
<pre>
</code>
But the (now) standard way of casting C++ classes take the form:
<pre>
<code>
CMyClass* pClass = static_cast<CMyClass*>(ParentClass);
</code>

okay.. i don't know if this is the right forum..
can anybody explain me the regular expression search & replace utility?
(or is there any documentation on this topic.. i couldn't find any)..
e.g. i want to change all the occurences of char XXX[] to const char* XXX
it would be something like
char(.*)?\[\] (at least as much as i know)
now i would have to replace this with const char* $1
how to do this with the find / replace dialog.
would be very handy if it worked..

Hi!
I tryed to use http://www.codeproject.com/treectrl/coptiontree.asp
During the compilation i got following error
MainFrm.obj : error LNK2001: unresolved external symbol Symbol "public: virtual __thiscall COptionTree::~COptionTree(void)" (??1COptionTree@@UAE@XZ)
MainFrm.obj : error LNK2001: unresolved external symbol "public: __thiscall COptionTree::COptionTree(void)" (??0COptionTree@@QAE@XZ)
MainFrm.obj : error LNK2001: unresolved external symbol "public: int __thiscall COptionTree::Create(unsigned long,struct tagRECT,class CWnd *,unsigned long,unsigned int)" (?Create@COptionTree@@QAEHKUtagRECT@@PAVCWnd@@KI@Z)
I've added the lib from COptionTree in my Project and put the DLL in my Debug folder.
What have i done wrong?
Thx mike

Do you include the header file for the lib?

Hi, I have a Small service which installs and runs fine on most machine, yet on some machines, when I try to install the service, using the CreateService() API function, the function hangs and I need to kill to process manually.
Any ideas?

Who knows why I can't type through Keyboard in dialog box after calling SetTimer function of CWnd object? I need to kill the timer everytime when the dialog box pop up for allow users to enter the data... it is very inconvenience...Please help...
Thank you.

Perhaps you could post the code what you are doing in the timer function?
Make sure you don't call any UpdateData(FALSE) without UpdateData(TRUE) in your timer function. Also make sure you don't disable, enable, or focus another control in the timer function.

hi,
i need dial up connection statistics (speed, send & received bytes etc.). i try to use RasGetConnectionStatistics function. it shows an error (RasGetConnectionStatistics' : undeclared identifier) but i include <ras.h>.
If do you know the solution, please help me.

Include file ras.h and link to rasapi32.lib.
You know that this function only works on Windows XP, Windows 2000 Professional, Windows Server 2003 and Windows 2000 Server, or?...
On Win95, Win98, WinME and WinNT this function won't work.

Hey Friends
I wish to Create a control just like Shape Control available in Visual Basic.It will be possible to Change its Shape and relocate to some other location.It should be visible properly.
I Tried Inheriting a Class From CWnd and Providing Body to OnPaint But the areas which i do not paint do not get updated and show the Background which looks Bad.
Pl Suggest.Will Regions Solve the Problem ?
Sample Code
void CShapeCtrl::OnPaint()
{
CPaintDC dc(this); // device context for painting
CRect rRect;
CBrush br;
GetClientRect(&rRect);
br.CreateSolidBrush(RGB(255,0,0));
dc.Rectangle(&rRect);
if(!m_bShapeSet)
{
HRGN hRgn;
rRect.DeflateRect(5,5);
hRgn = ::CreateEllipticRgnIndirect(&rRect);
SetWindowRgn(hRgn,TRUE);
m_bShapeSet = TRUE;
}
}
|
|
|
|
|
You need to call SetWindowRgn() in OnCreate(), and whenever the shape changes, not each call to OnPaint(). If it still updates incorrectly (although it should work), then try setting the WS_EX_TRANSPARENT extended style for the control.
Hope this helps,
Ryan

This is an SDI application. I wish to perform some initialization in OnInitialUpdate(). But to my horror, I discovered that OnInitialUpdate() is not getting called at all! I know I didnt add some piece of code required to do this, but am not sure what it is and how to do it. Could someone pls guide me?

I have a ListView control and I want it to do something when the user presses enter. So, I have put in a case for LVN_KEYDOWN, which seems to work fine for most keys except enter. I never recieve a VK_RETURN in the wVKey member, no matter how much I press the button 
So, is there some style I need to set or something? What do I need to do to be notified when the user presses enter in the ListView control?
Thanks,
Melekor

This question is asked so often, I'm disgusted at how many people don't search the forum before asking questions. It must have been asked 5 or 6 times in the last week 
Override PreTranslateMessage() in your dialog and check for WM_KEYDOWN where wParam == VK_ENTER.
If you're not using MFC, it shouldn't be a problem - just check in your message loop.

Same for me. If you only knew how many times I've answered the question "How do I change the caption of my window" or "How do I convert my CString into a ..."  I think the link to Mike's C++ FAQ should be as big as the advertisement banner, and even that would not help  .

I can guess. I visit the VC++ forum a few times a day, so I see all the questions.

Unfortunately it probably wouldn't. I lot of people who ask questions don't appear to be interested in helping themselves. They just want other people to solve all their problems.
