NiceNaiduTo convert this to const char* ,can i use (LPCSTR)strTest ??
Yes, but the cast is unnecessary. Others have explained this.

neither of those two methos r correct, because both of them return LPTSTR OR LPTSTR, but they r different to char *, when UNICODE is defined beforehand, then LPTSTR equiles w_char *. so I think u should judge if the UNICODE is defined to decide how to convert to char *

C does not support Class concept,
So replace all the Classes with structures and try.

whhich compiler u r using ?
if u r using a C compiler make the class definition in
#ifdef __cplusplus
// class Definition
#endif

CMenu* menu = GetSubMenu(2);
for(int i = 0; i < menu->GetMenuItemCount(); i++)
{
EnableMenuItem(i, MF_BYPOSITION | MF_GRAYED);
}
DrawMenuBar();
I used this code to disable my second menu.But the error comes like..
'GetSubMenu' : function does not take 1 parameters
'EnableMenuItem' : function does not take 2 parameters
I think the parameters are correct,then why its coming like this.

I changed the code as this..
CMenu* pMenu = AfxGetMainWnd()->GetMenu();
CMenu* Menu = pMenu->GetSubMenu(2);
for(int i = 0; i < Menu->GetMenuItemCount(); i++)
{
EnableMenuItem(i, MF_BYPOSITION | MF_GRAYED);
}
DrawMenuBar();
This time the error is come only EnableMenuItem()
|
|
|
|
|
CMenu m_Menu;
m_Menu.GetSubMenu(position);
------------------
GetSubMenu(hMenu,Postion);
------------------
CMenu m_Menu;
m_Menu.EnableMenuItem(i, MF_BYPOSITION | MF_GRAYED);
------------------
EnableMenuItem(hMenu,i, MF_BYPOSITION | MF_GRAYED);

I could not understand what is hMenu..Is that handle for Menu.
|
|
|
|
|
HMENU is handle to point a menu.
it is used in Win32.
in MFC we are using CMenu instead.

there are a lot of articles and sample snippets included in MSDN. If u r using an old MSDN look at MSDN.com

if you use one project Win32 use
GetSubMenu(hMenu,Postion); that hMenu is one handle to menu if your project is MFC
you can use CMenu Menu; and you dont need to parameter hmenu for menu functions m_menu.GetSubMenu(pos)

U should pass HMENU which points the parent menu.
e.g:
<br />
CMenu* pMenu = pMain->GetMenu();<br />
CMenu* pSubMenu = pMenu->GetSubMenu<br />
<br />
pMenu->DeleteMenu(0, MF_BYPOSITION);<br />
for(int i = 0; i < pSubMenu->GetMenuItemCount(); i++)<br />
{<br />
pSubMenu->EnableMenuItem(i, MF_BYPOSITION | MF_GRAYED);<br />
}<br />
DrawMenuBar();<br />
}<br />
I think u need to add MF_DISABLED flag, else it will just change the menu color to gray. it wont disable the menu item

Good point. I think you might actually need both, so it's disabled and grayed (MF_DISABLED | MF_GRAYED).

GetSubMenu and EnableMenuItem are members of CMenu, so you need to get access to the main menu like (this is from MSDN):
CMenu* menu = AfxGetApp()->m_pMainWnd->GetMenu()->GetSubMenu(2);
and then:
menu->EnableMenuItem(i, MF_BYPOSITION | MF_GRAYED);

Hey Anu, before u ask the forum, just Check the MSDN for such small syntax errors. No Offence.
Syntax of GetSubMenu,
It Looks like this :
HMENU GetSubMenu( HMENU hMenu,<br />
int nPos<br />
);
where hMenu can be retreived by
HMENU GetMenu(this->m_hWnd);
EnableMenuItem syntax Looks like this :
BOOL EnableMenuItem( HMENU hMenu,<br />
UINT uIDEnableItem,<br />
UINT uEnable<br />
);

Hi fellows.
I realized that with Visual C++ 8 it is possible to add comments in a C#-style:
<br />
class CMyClass<br />
{<br />
...<br />
};<br />
and that the compiler generates an .xml file, such as in C#. My question is the following: is there any tool such as NDoc that could process this .xml file into an HTML file?
Regards,
FG.

The classic free tool which does (something like) this is Doxygen. It can parse C++ by itself and so doesn't require compiler support.

But Doxygen does not support <summary>...</summary> comments, does it?
I know there are other tools, particularly I prefer C++ Doc (www.cppdoc.com), but I'm looking for a tool that works with VC++ 8 comments.

Doxygen has a bewildering array of tags, although the syntax is different. It supports any C++ compiler.

Thanks Steve. Normally, I use cppdoc; of course, Doxygen is an option -as many others. However, I'd like to know if there is a tool for the file generated by Visual C++ 8, the xml file.

Hi All,
I have implemented context menu extension on my Namespace Extension icon. I have added 4 menus in my QueryContextMenu function. This works fine in Windows 2k. But I am able to see only the first menu added by me when I test it on WinXP or on Win2k3.
Also, explorer crashes when the user selects the "Create Shortcut" menu on win 2k.
Can anyone tell me what may be going wrong here?
Thanks and Regards,
Anil

This is how I implemented my QueryCOntextMenu
STDMETHODIMP MyShellFOlder::QueryContextMenu(HMENU hMenu, UINT uiIndexMenu, UINT idCmdFirst, UINT idCmdLast, UINT uFlags)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
m_hMenu = hMenu;
m_idCmdFirst = uiIndexMenu;
m_id = idCmdFirst;
if (CMF_DEFAULTONLY & uFlags)
return MAKE_HRESULT(SEVERITY_SUCCESS,FACILITY_NULL,0);
int i = uiIndexMenu;
MxSNECmdMgr cmdMgr;
try
{
if(!cmdMgr.IsConnectedFromShell())
{
MENUITEMINFO mii = { 0 };
mii.cbSize = sizeof(MENUITEMINFO);
mii.fMask = MIIM_ID | MIIM_TYPE | MIIM_STATE;
mii.wID = idCmdFirst + ID_CONNECT;
mii.fType = MFT_STRING;
mii.dwTypeData = _T("Connect");
mii.fState = MFS_ENABLED;
bool b = InsertMenuItem(hMenu, uiIndexMenu++, TRUE, &mii);
mii.cbSize = sizeof(MENUITEMINFO);
mii.fMask = MIIM_ID | MIIM_TYPE | MIIM_STATE;
mii.wID = idCmdFirst + ID_SEARCH;
mii.fType = MFT_STRING;
mii.dwTypeData = _T("Search");
mii.fState = MFS_DISABLED;
b = InsertMenuItem(hMenu, uiIndexMenu++, TRUE, &mii);
mii.cbSize = sizeof(MENUITEMINFO);
mii.fMask = MIIM_ID | MIIM_TYPE | MIIM_STATE;
mii.wID = idCmdFirst + ID_CREATEUSINGTEMPLATE;
mii.fType = MFT_STRING;
mii.dwTypeData = _T("Create Using Template");
mii.fState = MFS_DISABLED;
b = InsertMenuItem(hMenu, uiIndexMenu++, TRUE, &mii);
mii.cbSize = sizeof(MENUITEMINFO);
mii.fMask = MIIM_ID | MIIM_TYPE | MIIM_STATE;
mii.wID = idCmdFirst + ID_DISCONNECT;
mii.fType = MFT_STRING;
mii.dwTypeData = _T("Disconnect");
mii.fState = MFS_DISABLED;
b = InsertMenuItem(hMenu, uiIndexMenu++, TRUE, &mii);
mii.cbSize = sizeof(MENUITEMINFO);
mii.fMask = MIIM_ID | MIIM_TYPE | MIIM_STATE;
mii.wID = idCmdFirst + ID_ABOUT;
mii.fType = MFT_STRING;
mii.dwTypeData = _T("About");
mii.fState = MFS_ENABLED;
b = InsertMenuItem(hMenu, uiIndexMenu++, TRUE, &mii);
}
catch(...)
{
}
return MAKE_HRESULT(SEVERITY_SUCCESS, 0, USHORT(i-uiIndexMenu));
