An binary will not be able to execute 'itself' after it's been downloaded. You either need a watchdog which will be monitoring the download to execute it upon completion. But as you already say that it is your own application that does the download, it could as well execute the file after download. If there are issues on specific computers, try logging the events from your application and find out what is causing this problem. You can use an external debugger like DebugView[^]to print debug strings (the name is misleading, works on release versions as well) if you wish not to use a log file.

I really thankful to you. I will have look at DebugView. But once again thank you. I am obliged.
Thanks & Regards,

You're most welcome. And I forgot to mention: The API which prints to DebugView is OutputDebugString. Look it up in MSDN.

how to get process start time in vc?

Use GetProcessTimes() or Sample Code[^]. Hope this helps and is relevant to your needs.
Somethings seem HARD to do, until we know how to do them.

Will API GetProcessTimes helpful ?

I created a dll file like this :
HHOOK MyHook;
HINSTANCE MyInstance;
LRESULT CALLBACK MyMouseHookProc(int nCode, WPARAM wParam, LPARAM lParam);
extern "C" __declspec(dllexport) void Hook();
extern "C" __declspec(dllexport) void Unhook();
BOOL CMouseHook1App::InitInstance()
{
CWinApp::InitInstance();
MyHook = NULL;
MyInstance = this->m_hInstance;
return TRUE;
}
void Hook()
{
if(MyHook == NULL && MyInstance != NULL )
{
MyHook = SetWindowsHookEx(WH_MOUSE,MyMouseHookProc,MyInstance, 0);
if(MyHook!= NULL)
MessageBox(NULL,_T(" HOOKED "), _T(""),0);
}
else
MessageBox(NULL,L" Not Hooked", L"",0);
}
LRESULT CALLBACK MyMouseHookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if(nCode <0)
{
CallNextHookEx(MyHook,nCode,wParam,lParam);
return 0;
}
if(wParam == WM_LBUTTONDOWN || wParam == WM_NCLBUTTONDOWN)
{
MessageBox(NULL,_T("OK"),_T("Test"),MB_OK);
PostMessage(hWndApp,WM_LBUTTONDOWN,0,0);
}
return CallNextHookEx(MyHook,nCode,wParam,lParam);
}
But in my app, when I use the function Hook(), it doesn't work at all. Did I do anything wrong? Someone plz help me

You need to declare the HHOOK MyHook; in a shared data section.
So you need to first create a data section, declare the HHOOK in that data section and then make that section shared.
Look at my article at

I am getting set hexa decimal values as I/P from user into a CString.
I am tokenizing this and get separate hexa values in another CString.
I want to convert this single hexa value in CString to unsigned char.
How to do this?
Or can I get input in unsigned char itself and tokenize is possible?
Thanks,
Suman

Use strtoul().

You already have the IP in number form so it should be easier for you to split it out byte by byte. Why to use CString in between?
Or if you are forced to do so then you can use functions like StringToAddress and AddressToString for converting ipaddress byte array from and to a string. Though not sure whether this will work with IP address in hex form.
Hope this helps!

Hi Nibu thomas,
Thanks for the help,
The input is some MIDI command like "0x90 0x00 0x01"
The separator can be space or comma.
If I get the above command, how to assign them to unsigned char array except separators if possible without CString?
I will try strtol() once which David crow recommended.
Thanks,
Suman

Well then you've got to convert it to byte form!

Suppose there are three classes Class A, Class B and Class C.
Class A
{
public:
//one virtual function
}
Class B
{
public:
//one virtual function
}
Class C:virtual public A, virtual public B
{
}
How many v-tables Class C has?
|
|
|
|
|
Only One.
Regards,
Paresh.

The point here is, when ever this class is inherited, a new virtual table is created for the derived class and if any of the virtual functions are overridden the function pointers in the new vtable will be overwritten with the new address which points to the new function implementation. Do keep in mind that for every class which implements/inherit virtual functions will have only 1 vtable per class.
Somethings seem HARD to do, until we know how to do them.

In a console app, I want to be able to test whether stdout and stderr are both printing to the screen. My output is messy unless I get it right (I'm printing to both stdout, and to stderr, and if they both happen to be the screen, I get two copies; I only want one copy on the screen).
A line like
<br />
if( stdout == stderr )<br />
always tests false under all the Windows compilers I've tried, so I get the duplication I'm trying to avoid.
Any ideas?

What about:
if (&stdout == &stderr) In any case, I would really expect them to not ever be *equal* even though they may resolve to the same location (i.e., screen).

That won't compile under Visual C++
The standard says that stdout and stderr are macros that evaluate to FILE pointer rvalues. Taking the address them seems suspicious from the outset...

From reading the MSDN site, I thought it would; but it doesn't do what I thought.
HANDLE stderrHndl = GetStdHandle(STD_ERROR_HANDLE);
HANDLE stdoutHndl = GetStdHandle(STD_OUTPUT_HANDLE);
...
(very incomplete!)
vfprintf( stderr, msg, args );
if( stderrHndl == stdoutHndl )
goto logprint;
vfprintf( stdout, msg, args );
logprint:
Because the stderrHndl == stdoutHndl is always evaluating to FALSE, I'm still double printing to the console.

If your output is being flooded why dont you just re-direct stderr to a file.
console_app 2> stderr.log
