CAtlArray in VC7 is very good. I used it in my no-STL tests and it saved tons of memory.

get 2 menus at same time

there are 2 menus in MDI mfc app, one is for main-frame, another one for child-window.

if no child window opened, the menu used is main-fram menu, otherwise is child-window menu.

GetMenu() only gets current menu. I want to get these 2 menus in one function - or at same time (child-window may be opened or not while the function is called), how to do that?

thx.

I don't understand what you want to do ? you want to always see the menu visible when a "child window" is openned ?

You will have to do the drawing yourself. The easiest way is probably to store the color in a COLORREF variable in the window which you want to change the background of. Update this variable with the new color and tell the window to redraw itself. Then intercept the WM_ERASEBKGND message and fill the background using this color value. There is a handy function in CDC that does exactly that -> FillSolidRect( ).

I think this is simple enough though the solution seems to be eluding me for almost a day now

i have a standard listctrl with checkbox ,say

m_list.SetExtendedStyle(LVS_EX_CHECKBOXES|LVS_EX_FULLROWSELECT);

what i want is to lock some of the list rows,say row 2
so that the check box value cannot be modified by the user

so i wrote the following in NM_CLICK

{
// TODO: Add your control notification handler code here
NMITEMACTIVATE* pLVCD = reinterpret_cast<NMITEMACTIVATE*>(pNMHDR);
LVITEM rItem;
int nItem = pLVCD->iItem;
ZeroMemory ( &rItem, sizeof(LVITEM) );
LVITEM rItem;
rItem.mask = LVIF_STATE;
rItem.iItem = nItem;
rItem.stateMask = LVIS_SELECTED|ODS_DISABLED;
m_list.GetItem ( &rItem );
if ( nItem ==2)
{
BOOL bSel=m_list.GetCheck(nItem);
m_list.SetItem(nItem,bSel);
m_list.Update(nItem);
}
*pResult = 0;
}

here if a checkbox is unselected and i click it
the control comes to the above code and bSel is FALSE and eventhough i say to update the list row 2 with that itself ...it doesnt work.

the rows check box gets selected invariable

i tried the same in LV_ITEMCHANGED and a couple of others as well...
but to no avail...

please put me out of my misery

what am i doing wrong??

1) an item does NOT have to be selected for the check to be checked/unchecked.

2) if you want to prevent the check from being checked... or unchecked... or prevent an item from being modified in any other way, just handle LVN_ITEMCHANGING and watch the status of the modified item (which, need i remind you, is not necessarily selected). If the state image changes (item state & LVIS_STATEIMAGEMASK), then the check has been modified. If you don't agree with the modification, then just return FALSE, and the change will not occur. Otherwise, return TRUE.

Customized Windows

Its second time Smile | :)

I hope you all've used MSN messenger. The window/GUI of MSN messenger is customizable and there are many custom add-ons present. I mean that we can customize the window of MSN messenger without having the access to the original source code.

I also want to make my window based application that i can customize later without accessing the original source code, just like MSN messenger. Can any one tell me how such applications are created ???

By exposing an interface, so that the code to *generate* these changes is present, and so is code to parse the add-ons. At least that is what WinAmp does.

I'm not on my Dev machine right now, so you might have to change some of the names of the members of the SHELLEXECUTEINFO struct.

SHELLEXECUTEINFO a_stInfo;
memset( &a_stInfo, 0, sizeof( a_stInfo ) );
a_stInfo.cbSize = sizeof( a_stInfo );
a_stInfo.lpVerb = _T("properties");
a_stInfo.lpFile = _T("C:\\YourFile.ext");
a_stInfo.fMask = SEE_MASK_INVOKEIDLIST;
ShellExecuteEx( &a_stInfo );

Determining Platform from WinCE DLL file

12-Nov-02 15:58

I'm supporting multiple platforms and want to make sure that the person who creates our CE installation package doesn't put a DLL for a MIPS device on an ARM device.....yeah I know I shouldn't have to do this, but I found that none of the correct files were on the device after a couple hours of trouble shooting.

Ideally I could read part of the DLL from the device and determine which platform it is supposed to run on.

Ideas??

Thanks,

One can only use fixed width fonts in the VC6 IDE. Which font do you want to use? It is probably a variable width font.
