I have a program that gets a set of 3 messages every second or so.
The message:
- hwnd is NULL (thread message, not window message)
- message is 49338 (0xc0ba)
- LPARAM, WPARAM change for each of the 3 messages
Messages between 0xc000 and 0xffff are string messages generated by RegisterWindowMessage().
I don't call RegisterWindowMessage, which leads me to believe either the debugger or another library (e.g. OpenGL) has created the message.
How can i find who called RegisterWindowMessage to get the message id 0xc0ba ?
And/or, how can i find what string was passed to RegisterWindowMessage ?

I don't think you can reverse the RegisterWindowMessage() function, but if you have Spy++ installed (it's part of the Visual Studio installation, Tools->Spy++) you can use it to find out which application is sending the messages. Run Spy++, use the Find Window dialog to pick your root window, choose the 'show messages' option and then hit OK. A window will pop up showing all the messages your application is receiving, and you can then find the offending messages.
You usually see lines in the Spy++ application that look like:
000D072C S message:0x1065 (User-defined:WM_USER+3173) wParam:00000000 lParam:00000000
000D072C R message:0x1065 (User-defined:WM_USER+3173) lResult:00000000
If you double-click on the 'S' line you'll see information about the sender of the message. Going to the 'Process' tab will then allow you to find out who's sending the message.
In my experience the usual culprits for sending out lots of messages like this are media players which broadcast information about where they are in the song so that third-party plugins can show song information etc.
I know this isn't quite an answer to your original question, but I hope it's useful!

Matt, thanks for the reply, but ...
I've been using Spy++ for years, it was the first thing i tried.
Unfortunately Spy++ doesn't seem to:
- show thread messages, only windows messages (i.e. message must have hwnd set)
- show information about the sender, nor do i see how it could, that information isn't present in a message structure
- doesn't seem to catch any messages for x64 apps (Spy++ is a 32bit app, so i can understand that - kinda)
I'm running Win2003 R2 x64, VS2005, debugging an app i can compile as 32 or 64bit.
Running Spy++ on the 32bit build show messages sent to windows, but doesn't catch the ones i'm looking for. I know the messages are being sent/caught because i have the debugger open at the same time and have a breakpoint set to catch the messages.
Oh well, i'll keep looking.

Blast! Sorry to preach to the choir there then! Good luck; and if you do find out a way to turn messages back into their registered strings, be sure to post back - I'd love to know!

Yes, well i originally thought they would be ATOM's ... i think they used to be.
To bad neither GetAtomName, nor GlobalGetAtomName find them now.

Hi rajeevktripathi,
I'm not sure this good way but maybe it is some helpful to you
DWORD dwR,DataSize;
HKEY hKey1;
TCHAR sz[MAX_PATH];
dwR = RegOpenKey (HKEY_LOCAL_MACHINE,
_T("Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell Folders"),&hKey1);
CStringArray m_Array;
CString str;
TCHAR m_Value[256];
DWORD m_dValue = 256;
DWORD m_Data;
for(int i=0;i<15;i++)//example
{
m_dValue=256;
m_Data = 256;
RegEnumValue (hKey1,
i,
m_Value,
&m_dValue,
NULL,
NULL,
NULL,
&m_Data);
m_Array.Add(m_Value);
}
for(int i=0;i

If you mean the pin list on the XP start menu, there is no programmatic access to this list, by design. You may be able to fool with it by grovelling in the registry, but that may break in future revs of the OS.

hi all
I want to check for a valid IP address.the code is as follows
CString strFileName=_T("C:\\Windows\\System32\\Ping.exe");
CString strIpaddress=_T("10.37.8.4");
if(!(int)ShellExecute(NULL,_T("open"), strFileName,strIpaddress,NULL,SW_SHOW) == ERROR_FILE_NOT_FOUND)
{
AfxMessageBox(_T("Successful"));
}
else
{
AfxMessageBox(_T("Ping Failed"));
}
The Problem is that when i execute this it opens the Ping.exe and it checks for valid address but the message box "Successful" is not displayed..instead "Ping Failed" is displayed even after executing Ping exe successfully.
What could be the problem??
Are there any other ways to check for Valid IP address(i.e URL name) like gethostbyname()??

QuickDeveloper,
maybe I mistake but,I think you need to change afxmessage(succes) with afxmessage(fail) because ping is run
ping is run (show Messagebox(successful))and show window ping that is reply from...
Hope I understood your question

If you just want to check if the IP address itself is a valid IPV4 address, you can use:
unsigned long ip = inet_addr("10.37.8.4");
if (ip == INADDR_NONE)
{
}
else
{
}
inet_addr() is to dotted quads what gethostbyname() is for host names.

Three problems:
One, your comparison is buggy. ! has higher precedence than == so the comparison isn't doing what you want. Rewrite it to use != which is clearer.
Two, your check of the return value is wrong. From the ShellExecute() docs:Returns a value greater than 32 if successful, or an error value that is less than or equal to 32 otherwise. Three (and most significant) ShellExecute()'s return value only tells you if the app was launched. It tells you nothing about what the app did.

I'll take a slightly different tack from the other responses.
Try checking out the IcmpSendEcho[^] function in the IP Helper library. This performs a 'ping' for you, and you don't have to worry about running a separate program.
