how are you placing the Static text on the dialog. i.e. are you using SetWindowText or included that in Resource file or giving value to any variable to display the static text at startup

How are you calling this update function on the dialog? Are you in a UI thread? If not, you can run into problems...

how are putting you image in MainFrame Window, i.e. View Window. have you overidden the OnDraw function for drawing image on View Window. you can use this class for display variety of image format on windows http://www.codeproject.com/bitmap/extendedbitmap2.asp[^]

I have an MDI app - and I wanted a less boring backdrop. The trick is to subclass the MDI Frame window - and then override WM_ERASEBKGND.
The below code uses CSubclassWnd by Paul DiLascia - you should be able to search for in from an old MSJ article on the web.
Good luck,
Iain.
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;
m_Backdrop.Install (m_hWndMDIClient, IDB_MIDAS, 32);
....
return 0;
}
class CUIMDIBackdrop : public CSubclassWnd
{
public:
CUIMDIBackdrop ();
~CUIMDIBackdrop ();
BOOL Install (HWND hWndMDIClient, UINT idBitmap, int nMargin);
protected:
virtual LRESULT WindowProc(UINT msg, WPARAM wp, LPARAM lp);
};
CUIMDIBackdrop::CUIMDIBackdrop ()
{
}
CUIMDIBackdrop::~CUIMDIBackdrop ()
{
}
BOOL CUIMDIBackdrop::Install (HWND hWndMDIClient, UINT idBitmap, int nMargin)
{
return HookWindow (hWndMDIClient);
}
LRESULT CUIMDIBackdrop::WindowProc(UINT msg, WPARAM wp, LPARAM lp)
{
if (msg != WM_ERASEBKGND)
return CSubclassWnd::WindowProc(msg, wp, lp);
HDC hDC = (HDC) wp;
CDC *pDC = CDC::FromHandle (hDC);
CRect rc;
::GetClientRect (m_hWnd, &rc);
return TRUE;
}

Hi all,
I have an application that create a process in suspend mode:
CreateProcess(filePath, 0, 0, 0, TRUE, CREATE_SUSPENDED, 0, 0, &startup, &procinfo);
and then later in code, we will run the program... so do a resume
ResumeThread(procinfo.hThread);
the problem I have is that the windows of the launched program does not appear. For example, if the create process is notepad.exe, when I resume the thread, the window of notepad does not appear and even not in the taskbar.
What is wrong with my approach?
thanks

send it a WM_RESTORE or WM_MAXIMIZE...
BTW, what are you trying to achieve here ?
|
|
|
|
|
How do I send it?
Trought the SendMessage() ? (If so, how to get hwnd)
or with startup.wShowWindow = SW_MINIMIZE; ?
I try to create a process of user's choice in suspend mode to analyse program and inject a monitor DLL. Then process is resumed so that program is used by user.

How are you initializing the startup structure?

Here is the initialization:
STARTUPINFO startup;
GetStartupInfo(&startup);
memset (&procinfo, 0, sizeof (PROCESS_INFORMATION));
memset (&startup, 0, sizeof (STARTUPINFO));
startup.cb = sizeof(&startup);
//start process in SUSPEND mode
CreateProcess(filePath, 0, 0, 0, TRUE, CREATE_SUSPENDED, 0, 0, &startup, &procinfo);

Shouldn't you be assigning a value, other than 0, to the wShowWindow member?

What is the difference between the following two statements?
1. if ((nID & 0xFFF0) == IDM_ABOUTBOX)
2. if ( nID == IDM_ABOUTBOX)
|
|
|
|
|
by doing nID & 0xFFF0, you're forcing the lower significant bytes to 0.
read this article[^] to understand the & operator better.

This only looks at the three most significant (upper) bytes, and then compares the result to IDM_ABOUTBOX.

Have to disagree, 0xFFF0 only represents 2 bytes or 16 bits, how can the expression look at three bytes? The expression nID & 0xFFF0 ignores only the lower 4 bits of nID.

Hello All,
how to get Current System Date in Long?
Any Help?
Manish Patel
|
|
|

The last Long equivalent Date type I heard of was in VB6, these days you'll probably need to do your own conversion or put up with storing at least 8 bytes. Have a look at the GetSystemTime and SystemTimeToFileTime API calls and their associated structures. A conversion to something like
<br />
struct LongDate<br />
{<br />
WORD Year;
WORD DayNumber;
};<br />
would be pretty trivial and you could shoe-horn that into a long.
Nothing is exactly what it seems but everything with seems can be unpicked.

Use the time() function.

Hi,
How can I know, that an application has been launched ?
Is there a windows event or something like that ?
Thank you for helping me.
Jphil

You can only know reliably if the launched application chooses to tell you. The best and most common way to do this, for example to prevent more than one copy of an app running, is to use a named Kernel object like a Mutex or Semaphore which can be accessed by name from more than one process and locked to prevent multiple usage. A shared named Kernel Event Object could be used if you simply want to watch for an app launch. If it's a 3rd party, black box app that you can't change then you'll either need to use some form of Dll injection to add the Event code to it or fall back to older unreliable methods like enumerating top level windows to look for an application specific name.

Matthew,
Thank you for you reply.
It gives me some clues.
In fact I want to control the launching of application developed by third parties.
You tell about DLL injection ? could you tell me more about that ?
Up to kow, I used a method based on the function "CreateToolHelp32Snapshot" to get a view of all running process. Of course I need to take a snapshot very often (in a loop). Hopefully, it seems no to take to much resources.
Once I see the launching of a new application I could kill it, if not authorized.
But the window of the application is displayed for a short time, which is no very beautifull !!
I'm sure that hackers can catch application launching.
Thank you for your help
Jean-Philippe

The principle of Dll injection is that you get the 3rd party app to load your dll into itself which gives you an opportunity to run some code, override window classes, install some hooks or whatever into an exisiting application. I'm no expert on this but there are articles on CP about it.
In this case your injected Dll would need to establish the command line of the executable that had loaded it, this info is accessible as part of the PROCESS_INFO structure which it should be able to retrieve. If this is an app you want to block then it would Set a named shared Kernel Event that your other process is already waiting on. It might also need some way of communicating the Process ID of the 'bad' process to the monitor, or you could kep the ToolHelp sapshot based scan and just trigger it on the event, or just get the Dll to kill the process itself, 
This may indeed be able to shut down the disallowed process before the user sees anything but it really is no substitute to preventing them launching it in the first place using the Windows user account permissions system.

Have you tried looking for the WM_CREATE message via SetWindowsHookEx(WH_CALLWNDPROC, ...)?

Using a global hook similar to the one above is what I used great success

I try a hook function CallWndProc to catch the WM_CREATE event.
The problem is that a lot of windows are created when a program is launched.
It is not easy to determine the first one. Moreover, the first one is not always the main window of the launched application.
Also the name of the executable is not returned by the Hook function.
Maybe is there another message ? I dind't see it !!
