I am invoking that dialog box through "Create" method and showing it through "ShowWindow(SW_SHOWNORMAL)" method, after some time when i will call "DestroyWindow()" method the dialog box will get destroyed, now the problem is that dialog box is getting invoked and displayed properly but the static text on it is not getting displayed means i can see only dialog box but not the static text on it, what can be the reason, can anybody help me plz?

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...

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)
{
    // load resources and other graphics stuff here
    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);

    // do pretty stuff here
	return TRUE;
}

Resume a suspend process

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

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?

Re: Resume a suspend process

inovah2-Nov-07 5:22

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?

Dialog ID comparision

What is the difference between the following two statements?

1. if ((nID & 0xFFF0) == IDM_ABOUTBOX)
2. if ( nID == IDM_ABOUTBOX)

Re: Dialog ID comparision

toxcct2-Nov-07 0:15

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?

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;//AD year - 1600<br />
  WORD DayNumber;//1-365<br />
};<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.

Catching the launch of an applicatin

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.

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
