Why are you using szProcess and strcpy()? They are completely unnecessary. Just pass szNewProcess directly to CreateProcess().

You are getting a "ghost" of the app. The system will create a dummy window that mimics the original when the original stops processing. Not sure why they did this, but thats the second window you're seeing. It won't actually do anything. Your best bet is to reengineer it so that you don't block in the original app while waiting for the second to close. Maybe disable the application window and start a thread that waits for the second app to finish, then enable everything again.

( using VS.net 2003, on Win2000 )
in MSDN, SetParaFormat can take either a PARAFORMAT or a PARAFORMAT2 structure.
how can I tell the compiler to use the version that takes a PARAFORMAT2 ?
now, when compiling it tells me that it cannot convert PARAFORMAT2 to PARAFORMAT ...
'DWORD CRichEditCtrl::GetParaFormat(PARAFORMAT &) const' : cannot convert parameter 1 from 'PARAFORMAT2 *__w64 ' to 'PARAFORMAT &'
This is what I'm doing
PARAFORMAT2 pf;
ZeroMemory( &pf, sizeof ( PARAFORMAT2 ) );
pf.cbSize = sizeof(pf);
pf.dwMask = PFM_ALIGNMENT|PFM_BORDER;
pf.wAlignment = PFA_CENTER;
pf.wBorderWidth = 5000;
m_RichEdit.SetParaFormat(&pf );
Thanks.

Use
m_RichEdit.SetParaFormat(pf); (No ampersand before pf)

oh crap, it's a reference !! 
it also works with
m_RichEdit.SendMessage( EM_SETPARAFORMAT, 0, (LPARAM) &pf );
thanks!

You have the answer to your problem, but not an answer to your question - the size of the structure tells the control what version it is. So if you set cbSize to sizeof( PARAFORMAT ), and then call SetParaFormat(...), the PARAFORMAT2-specific things will be ignored.

I have to supplement our message window in our application; right now, it's an owner drawn control from dundas, which is enough for simple one line message ( fonts, colors, ... ) and easilly modifiable to add support for icons.
But now I have to be able to do more complex things, mainly tables.
I want to use HTML ( with gary wheeler's webbrowser control ) but while it's working, it prooves to be hard to make it work like a message window; for example scroll to bottom each time a new message is added, I need to regenered the whole HTML and re-load it and then scroll back down ... which flickers the control ( scroll up when reloading, scroll down ).
Is it possible to use RTF to generate simple table formatting ? I looked at what Word generates for a simple table, and it's unreadable ... so that's probably a no-no ...
Are there any other technology that I could use ?
Thanks.
Max.

Well, if you use the standard IE control, you can append to it by manipulating its document object (I think), so you do not have to worry about reloading and re-rendering the entire log/message.
Just a thought...

Hi,
Can anyone suggest some website or an article posted here, which gives some introduction:
1) how to Manage loading of Menus, Toolbars, Bitmaps etc.,
2) How MFC loads all these and especially when a Context menu is loaded.
i see in many places, where, there is a function call to load an image and immediately it is detached.
If someone can post an article on that, i would be grateful.
thnx,
KAB

Is there any tool for finding the Resource leaks ?

I am maintaing an application with mixed code. Some is C++ and follows the OO paradigm some it dates back 1980 and follows the standard C style. I am trying to get function references from member functions to assign them into old fashion function pointers. If I can do I may have a listeners pattern in the old code. I tried a small example like
<br />
#include <afx.h><br />
#include <stdio.h><br />
<br />
typedef int TBK_BOOL;<br />
<br />
#define TBK_TRUE 1<br />
#define TBK_FALSE 0<br />
<br />
typedef void (*TB_LISTENER_NOTIFICATION_FUNCTION)(<br />
TBK_BOOL value);<br />
<br />
class Listener<br />
{<br />
private:<br />
int identity;<br />
<br />
public:<br />
Listener() {identity = 0; };<br />
<br />
void setId(int id) { identity = id; };<br />
int getId(int id) { return identity;};<br />
<br />
void notify(TBK_BOOL note);<br />
};<br />
<br />
void Listener::notify(<br />
TBK_BOOL note)<br />
{<br />
if( note )<br />
printf("Object no %d was notified\n", this->identity);<br />
else<br />
printf("Object no %d was left asleep \n", this->identity);<br />
}<br />
<br />
int main(int argc, LPCSTR argv [])<br />
{<br />
Listener x;<br />
Listener y;<br />
<br />
TB_LISTENER_NOTIFICATION_FUNCTION lists[2];<br />
<br />
x.getId(1);<br />
y.getId(2);<br />
<br />
lists[0] = x.notify;
lists[1] = y.notify;
<br />
(lists[0])(TBK_FALSE);<br />
(lists[1])(TBK_TRUE);<br />
}<br />
And I received the following compilation errors
G:\func.cpp(45) : error C2440: '=' : cannot convert from 'void (__thiscall Listener::*)(int)' to 'void (__cdecl *)(int)'
There is no context in which this conversion is possible
G:\func.cpp(46) : error C2440: '=' : cannot convert from 'void (__thiscall Listener::*)(int)' to 'void (__cdecl *)(int)'
There is no context in which this conversion is possible
Is anyway that I can do what I am trying or should I abandon the idea of referencing object functions outside of it??

as notify() is a member of a class, then it implicitely receives the this pointer as a parameter...
to solve this, declare it like this :
static void notify(TBK_BOOL note);

You can't (as you've seen) assign a pointer to a member function to a normal function pointer. A pointer to a member function would look like this:
typedef void (Listener::*)(TBK_BOOL note) NEW_LISTENER_NOTIFICATION_FUNCTION;
To call this pointer you would need more information then with a normal function pointer, you need to supply the this pointer. A call could look like this:
Listener x;<br />
NEW_LISTENER_NOTIFICATION_FUNCTION pFunc = &Listener::notify;<br />
(x.*pFunc)(Some_Value);
The functionality you're after seems more like a delegate then a C++ style member pointer. I believe there is an article on the code project which provides such delegates - but these can only be used from C++.

It doesn't modify the class but it does access a member variable. I assumed that in the real implementation the function would be more elaborate.

Hi
I have a dialog based MFC application in which I want to handle an event which occurs when user presses Ctrl+Alt+Del and from Windows Security dialog it select "Lock Computer" button and it locks the computer.
I want to know which event occurs and how to trap this event?
Any help would be strongly appreciated.

IIRC, you cannot "trap" the SAS (CTRL-ALT-DEL) due to security reasons.
I am not sure if applications can register (or receive) notification that the system has been locked.
You can also see an earlier post I made about Desktops in http://www.codeproject.com/script/comments/forums.asp?msg=1362087&forumid=1647#xx1362087xx[^].
Peace!

Receiving notice when Ctrl+Alt+Del has been pressed will require your own GINA DLL. However, whenever the computer has been locked, see ISensLogon::DisplayLock().

Hi David...
Thankx a lot for giving some time to my problem
Isn't there any such message which we receive when it locks computer by pressing "Lock Computer" button. Like we receive "WM_QUERYENDSESSION" when it goes logoff event or shutdown event.

Perhaps, but I'm unaware of what it might be.

This seems like a Terminal Services solution, rather than a general-purpose one. Yes?
