i open spy++ and i right click\propeties.i see winproc:001....(address) of a window
may i redefine this winproc of this window to send WM_KEYDOWN.
because this window had security...i can't sendmessage,postmessage,defwinproc
can you help me .
thanks so much

That's more or less the primary purpose of having security there. Without it, the opportunities for hackers and writers of viruses would be truly endless. Access to the victim's e-mails, social networks, and bank accounts would be just a few WM_KEYDOWN messages away!

i have 2 class CControl and CMainFrame ( MFC), in CControl i have a function
void CControl::OnButtonRun()
{
// TODO: Add your control notification handler code here
CBaocaoDoc *pDoc = GetDocument();
if(pDoc->dc_status)
{
if((pDoc->nc_status) && (pDoc->phoi_status))
{
m_feetrate.SetRange(0,1000,TRUE);
UpdateData(TRUE);
m_fr=temp_mfr; // lay toc do
m_feetrate.SetPos(temp_mfr); // set toc do
SetTimer(2,1000,NULL);
UpdateData(FALSE);
}
else MessageBox("Chua chon chi tiet hoac file","Thong bao",MB_OK);
}
else MessageBox("Chua xuat file chua duong dung cu","Thong bao",MB_OK);
}
now i want call OnButtonRun() from CMainFrame, if i call function like
void CMainFrame::OnImportfile()
{
// TODO: Add your command handler code here
CControl abc;
abc.OnButtonRun();
}
MFC have error C2248: 'OnButtonRun' : cannot access protected member declared in class 'CControl'
please, help me, thanks .

I'm assuming the OnButtonRun function is an event handler.
I'm further assuming that this function is called on a button click.
You can send the BN_CLICKED message to the button to simulate the button click which will then call the OnButtonRun function -
abc.SendMessage(WM_COMMAND, (BN_CLICKED << 16) | BUTTON_ID, abc.GetDlgItem(BUTTON_ID));
Having said this, you may need to access the already existing instance of CControl instead of creating a new instance of it.

there's a couple of ways to do it, one is using SendMessage() or PostMessage() to message the event handler (as someone has already suggested, this is the proper way)... here's another resource for how to do it:
Scroll to the bottom of the page for solutions:
http://www.experts-exchange.com/Programming/System/Windows__Programming/MFC/Q_21374701.html[^]
if you've defined CControl yourself, then you can take a shortcut and just make the method public (by doing this you're ignoring the framework)
I noticed that you're also creating CControl when you call it, that doesn't really make sense if the control is also associated with something in the GUI since you're creating this on the stack that means it'll be gone after the execution of OnImportfile()

(If a mod has a better idea of where to move this question then by all means move it. I figure this forum is the closest match due to the increased odds that a professional C/C++ programmer would know about Git)
I am trying to insert a commit below the current initial-commit in a git repository. This is a local project/repository that isn't being shared, so my evil intentions won't affect others :P
The closest i've gotten was following the instructions here: http://stackoverflow.com/questions/645450/git-how-to-insert-a-commit-as-the-first-shifting-all-the-others[^]
Unfortunately those instructions discard all branches coming off of master, which i don't want to happen.

Hello community,
I need to show html pages in mfc dialog.In this mulitThread application,i used WebBrowser control in main thread to make it work,but the cpu usage is high up to 50%.Is there any resources should to be released?I can,t find the reason.
Complier is visual studio 2008, mfc 9.0.
Thanks for any help!

Never had any problems of this kind. Does your page contain dynamic elements, like flash components and the like? How does the page perform when displayed in a stand alone browser, i.e. IE?

I've got the following file header structure with every field ending by '\0':
struct CF_HEADER
{
TCHAR strIdentifier[7];
TCHAR bHasPath[2];
TCHAR bOrder[2];
TCHAR nTime[4];
TCHAR nEffect[2];
TCHAR nNum[3];
TCHAR nPos[3];
};
Then I initialized a UNICODE .txt file with this header. And in the file the following can be seen by Notepad:
XXXXXX 0 0 000 0 00 00
Of course there're times when these data should be updated. One of these functions to update the bOrder field is like this:
CF_HEADER m_cfhdInfo;
CFile file;
...
void SetOrder(BOOL bOrder)
{
_itot_s(bOrder, &m_cfhdInfo.bOrder[0], sizeof(TCHAR), 10);
updateHeader();
}
void updateHeader()
{
file.Seek(2, CFile::begin);
file.Write(&m_cfhdInfo, sizeof(CF_HEADER));
}
When I called SetOrder(TRUE), things proved weird. The following data can be seen in the file by Notepad:
XXXXXX 01 000 0 00 00
However, I had expected the results like this:
XXXXXX 0 1 000 0 00 00
Anyone could help? Thanks in advance.

Should be
_itot_s(bOrder, &m_cfhdInfo.bOrder[0], sizeof(m_cfhdInfo.bOrder)/sizeof(m_cfhdInfo.bOrder[0]), 10);
Anyway both give the same result, I suppose.
Why are you using 'generic text mapping' while producing a UNICODE file?

Yes, they turned out to be the same.
BTW, I reckon I need use wchar_t instead of TCHAR......as you said...
anyways, thank you all the same

Could you please post the code that fills the struct at first (the one that produced the right ouptut)?

Are you sure TRUE is defined as 1? I know in MFC it is, but I've seen implementations that use the definition
#define FALSE 0
#define TRUE (!FALSE)
I don't see how this could be the cause of your problem, but it might add to it.
Also, have you checked the type BOOL is in fact defined as int and not overwritten by some old header? Wouldn't be the first time I've seen conflicting macro definitions...
You could of course overcome such issues by explicitely defining an int variable that holds the intended value:
void SetOrder(BOOL bOrder) {
int iOrder(bOrder?1:0);
_itot_s(iOrder, ...
P.S.:
I just checked the definition of the not operator '!', and it appears my above example
#define TRUE (!FALSE) would in fact result in the definition
#define TRUE true (provided you have a modern C++ compiler that supports the type bool). In a context that requires an int, true would be converted to 1 as required by the standard, so the concern I brought up can in fact not be a problem at all, and my workaround is uncalled for.

Hello community,
i need to determine the control under the cursor, to call "vertical scroll" event for it!
I have two CListCtrl-controls in my dialog, so if the mouse is over one of them,
it should be possible to scroll in this control without clicking inside of control!
Just like in MS Outlook, if mouse is over "preview" area, you can use mouse wheel without clicking in this control to scroll!
Thanks for any help!

Well the cheap and cheerful way would be to call WindowFromPoint[^] when you have a WM_MOUSEWHEEL message. That will return the handle of the window/control under the mouse, then you can just SendMessage it the scroll.

Hello,
thanks for answer,i try to do this, but there is an little problem
when i use WM_MOUSEWHEEL windows catch this event only i my mouse is not over a CListCtrl! 
But i need to use when is OVER an CListCtrl, to set set focus to this list control!
regards
Arrin

Try adding the wm_mousewheel handler in the dialog class. This message is always sent to parent first and then passed down to children

Hello,
thanks for suggestions, it works with WM_MOUSEWHEEL message!
Best regards
