I think is the best place to use it.
In the constructor you may have error/assertion because the window is not already created so you dont have any possibility to access visual controls, m_hWnd will be NULL and give you problems.
But in OnInitDialog all the objects are already created and it is called the very first time the dialog and its components are shown in the screen.

you have to regularly handle teh OnCtlColor message for coloring the check box, and have to use SetTextColor there!

What kind of libraries do you link against?
Is there a UNICODE version to link against?

You can either compare the individual members of the tm structure, or look at difftime(). If you are using MFC, check out CTimeSpan and COleDateTimeSpan.

Hi,
In one of my coding,i found the coding for bitmap button in the dialog.
it shows as
//mainfrm.h
public:
CMainFrame();
CSysWindow m_SysWnd;
CBitmapButton bmSCopy;
//mainfrm.cpp
m_SysWnd.SetBarStyle( m_SysWnd.GetBarStyle()| CBRS_ALIGN_TOP|CBRS_BORDER_TOP | CBRS_FLOAT_MULTI );
bmSCopy.AutoLoad(ID_SCOPY,((CWnd* ) ((CDialogBar *)((CSysWindow*)&m_SysWnd)) ) );
I dont know here where the bitmap image is get loaded in the button.
ID_SCOPY is the ID for button.
CSyswindow is CDialogBar class.
ANd it perfectly working.After executing, the button has the bitmap image what i made the image for that particular button.
I dnt know how its get loading.Pls clear me.

For load bitmaps on the a control of CBitmapButton it uses of LoadBitmaps.
|
|
|
|
|
In that coding, i didnot find Loadbitmaps function anywhere.

For the button caption “MYIMAGE,” for example, the IDs would be “MYIMAGEU,” “MYIMAGED,” “MYIMAGEF,” and “MYIMAGEX.” You must specify the ID of your bitmaps within double quotes.

Yes, I found that. Thank u so much

See shortes code for notepad if helpfuls
CWnd *pwnd=FindWindowW(_T("NotePad"),NULL);
HMENU h=::GetMenu(pwnd->m_hWnd);
HMENU h2=GetSubMenu(h,0);
::SendMessage(pwnd->m_hWnd,WM_COMMAND,(WPARAM)3,(LPARAM)h2);

Yeah I understood it was for example.
if you have handle to that program you can use of this code for get handle to other controls on that forum and then send your message to a control.
for(CWnd* pWnd = needsto handle; pWnd;pWnd = pWnd ->GetNextWindow())
{
pWnd ->GetWindowTextW(str);
}
|
|
|
|
|
you must get the control id first. to get control id, you can use FindWindow and GetDlgCtrlID()...
then:
HWND hWnd = FindWindow(....);
::SendMessage( hWnd, WM_COMMAND, nButtonID, 0 );
|
|
|
|
|
Send WM_COMMAND message to the parent of the button, and set the WPARAM and LPARAM as follows
wparam = MAKEWPARAM( <id of="" the="" button="">, BN_CLICKED );
lParam = (LPARAM)<handle of="" the="" button="">;

Hi all,
There is a api which is used to find files inside the folder/Directory. Can anybody please tell me that api name.
Thanks in advance
|

Use CFile.
Make object of CFile and using that object open a file with file name. If File exist than it returns nonzero otherwise it will return zero.

You can use CFileFind(MFC) or WIN32_FIND_DATA(WIN32).
