2. the irregular window appears automatically when i start the program;
3. the shape of the window is according to a inputted picture. some color wish to be ignored, for example: white, then the part of the picture i wanted becomes irregular;

Hi ,
There is an API called SetWindowRgn(), look this API in MSDN.using this API one can create a window
of any shape and size.u can create a CRgn Object, which holds the shape information of your window.
and passing this Object in the above API u can create a Window of ur desired shape and size.

I had builded my application with html context-sensitive Help, according to an article in msdn.microsoft.com "Displaying Context-Sensitive Help". It works but sometimes there was a "debug assertion failed" message box appeared, it said:
Program: ....
File:wincore.cpp
Line:875
and line 875 in wincore.cpp is( in void CWnd::AssertValid())
ASSERT(::IsWindow(m_hWnd));
I don't know why. Who could help me? Thanks a lot.
The help function in my application as following:
BOOL CMyFormView::OnHelpInfo(HELPINFO* pHelpInfo)
{
DWORD dwHelpID[] =
{
IDC_DOSESCALE_SELGRAY_STC_ADJUSTPANE, 0x61000,
...
0,0
};
if (pHelpInfo->iContextType == HELPINFO_WINDOW)
{
return HtmlHelp(
(HWND)pHelpInfo->hItemHandle,
"MyHelp.chm/ctrlhlp.txt",
HH_TP_HELP_WM_HELP,
(DWORD)(LPVOID)dwHelpID)
!= NULL;
}
return TRUE;
}
In ctrlhlp.txt:
.topic 0x61000
help text for control 0x61000

I am looking how to measure the performance of the set.h file in the Standard Template Library. This is for a homework assignment. We are required to modify the set.h file with global integer variables to do the following:
I need to know how to count the number of compares and data moves that take place when loading N number of strings into a set or multiset. I tried to open up the set.h and increment counters in a few places, but I have no idea which functions do what. The set.h file is very confusing to me.
Any help is appreciated.

i've declared int iGlob in a header file. then get error:
error C2039: 'iGlob' : is not a member of '`global namespace' for this code:
void myGlob()
{
::iGlob = 123;
}
why?
|
|

Did you extern the global variable in that .cpp file.
The World is getting smaller and so are the people.
|
|
|
|
|
i tried
extern "C"
{
#include "_Globals.h"
}
and
extern int iGlob; in cpp file.. but no luck.
i know this is probably trivial stuff,
how about an example?
.cpp file: ...
.h file: ...
Dlg file: ...
thanx

i dont konw which compiler you are using but this works for me.
---in global.h----
extern int uGlobal;
---in global.cpp---
int uGlobal;
---place where you will need that variable---
#include "global.h"
void somefunc()
{
uGlobal = 55;
}
all the files must be in the project, compiled and linked.
Hope i got you rite and answeredit correctly.

found the solution on CP's FAQ....
6.2: How do I share a global variable among my .CPP files? (top)
First, in one of your .CPP files (and only one) declare the variable at global scope (that is, outside of all function and class definitions). For example:
int g_volume;
Then in a header file that is included in all .CPP files - such as stdafx.h - add an extern declaration:
extern int g_volume;
The extern keyword tells the compiler that g_volume is an int declared in some other .CPP file. If you forget the first step, the linker will give an unresolved external error.

Is it redistributable?

It's part of windows - it must be totaly redistributable.

It's not part of Win9x/ME, so it might not have been redistributable. But it so happens that it is redistributable.

In other words; MS won't be pissed if I redistribute it in an app which will run (mostly) on win2k?
I saw a discussion on this a looong time ago. I wish I had payed more attention.

Hi anyone know where in the registry the default email client is located and is it the same in all window flavors?
Best Wishes,

Files with extension *.eml are opened by the default mail client when double clicked.
HKEY_CLASSES_ROOT +
the default value of
HKEY_CLASSES_ROOT\.eml
which is on my XP
"Microsoft Internet Mail Message" +
shell\open\command
contains the registry key with the full path and command line of the default mail client:
so look at the default value of
HKEY_CLASSES_ROOT\Microsoft Internet Mail Message\shell\open\command
This is
"%ProgramFiles%\Outlook Express\msimn.exe" /eml:%1
on my XP without Office being installed.

Great stuff Peter! To explain I want to store the mail client information for later use.
Yes I too only have OlExpress but I like it. As for office they want so much for 2003 I went open office.
Seems that HKEY_LOCAL_MACHINE\\SOFTWARE\\Clients\\Mail\\ is the path on the new os's but do you know if it would be good on all 32b os's?
HKEY_CLASSES_ROOT\Microsoft Internet Mail Message\shell\open\command
If I use your idea will that return the complete path or as you said
"%ProgramFiles%\Outlook Express\msimn.exe" /eml:%1
Also Sardaukar wrote in part in his artice "Detect and run the default mail client" codeproject 2002
BOOL GetCmdLine()
{
LONG retval;
retval = Open(HKEY_LOCAL_MACHINE, m_szDefMailClient);
if(retval == NO_ERROR)
{
DWORD cbData = _MAX_PATH;
retval = ReadString(m_szDefMailClient, cbData);
if(retval == NO_ERROR)
{
TCHAR szCmdLine[_MAX_PATH + 1];
lstrcpyn(szCmdLine, _T("SOFTWARE\\Clients\\Mail\\"),
_MAX_PATH + 1);
_tcsncat(szCmdLine, m_szDefMailClient, _MAX_PATH + 1);
_tcsncat(szCmdLine, _T(\\shell\\open\\command),
_MAX_PATH + 1);
RegKey_ rk;
if(rk.Open(HKEY_LOCAL_MACHINE, szCmdLine) == NO_ERROR)
{
retval = rk.ReadString(m_szDefMailCmd, _MAX_PATH);
if(retval == NO_ERROR)
{
return TRUE;
}
}
}
}
return FALSE;
}
Problem it does not work on all os's.
Any idea's??

With the key HKEY_LOCAL_MACHINE\\SOFTWARE\\Clients\\Mail\\ the problem is that some other (non M$) mail client/or older M$ clients might not support it.
The above suggestion of mine uses the way the OS works, i.e. looking up the associated exe file of the email file extension, and as such should always work. Never assume that the default value of HKEY_CLASSES_ROOT\*.eml is "Microsoft Internet Mail Message", always look for its value. That's what the OS does, too, when you doubleclick a file.

Just one more thing:
You can also look for the default value of
HKEY_CLASSES_ROOT\mailto\shell\open\command
which gets looked up by the OS when you click on a <a href='mailto:...'> in a webpage, and that on all OS's.

void CTestDlg::OnButton1()
{
HKEY hkey;
char szKey[1024];
strcpy(szKey, "\\mailto\\shell\\open\\command");
if (RegOpenKeyEx(HKEY_CLASSES_ROOT,
szKey,
0,
KEY_QUERY_VALUE,
&hkey) == ERROR_SUCCESS) {
// Do something!
RegCloseKey(hkey);
}
}
Yes fine work, GREAT Help!
Here is where I am, I can find the key but now I must read it in place it in var.
I was thinking I could use RegQueryValueEx but it return LONG...
Will let you know later
Thank you so very much!
LONG RegQueryValueEx(
HKEY hKey, // handle to key to query
LPTSTR lpValueName, // address of name of value to query
LPDWORD lpReserved, // reserved
LPDWORD lpType, // address of buffer for value type
LPBYTE lpData, // address of data buffer
LPDWORD lpcbData // address of data buffer size
