I want to determine, a file is text file or binary file(file name dosen't have file extension).Is there any API in Windows SDK?

Thanks

You can open the file, read the contents, and examine the bytes to determine if the file contains any binary data. You can see if the characters are in the normal text range, as well as checking for CR/LF characters.

onwards and upwards...

A file is only "text" or "binary" in the context of the application that created it. Historically speaking, if the file contained non-printable characters, it was considered binary. Otherwise, it was considered text.

What exactly is it that you are trying to do?

I don't think so. This wouldn't make any sense to me. After all, a binary file appears as garbage in a text editor because the bytes will not map to ascii to form any kind of intelligible sentence in any language. The text editor doesn't care if the file you tell it to open is binary or not. It will just read the file and try to map the bytes into ascii and display whatever random characters the data happens to map to. If there were an automatic function for doing this, the people that wrote notepad and wordpad probably would have popped up an warning message reading, "warning, processing binary file"; or something like that.

All files are binary files, in my mind. It just so happens that a text file is a special kind of binary file where each byte maps to an appropriate ascii symbol to form intelligible letters/numbers/symbols. Even the carriage returns and line feeds are simply bytes of data that map to the appropriate ascii symbol. I think writing an algorithm to guess if something is good enough to be a text file would be awfully difficult if not impossible. You'd have to read each byte in and make a lot of assumptions about the data.

Search for Iphlpapi.h on your machine. Mine is in the \program Files\Microsoft SDK\include directory (your could be else where).

If it doesn't exist install Microsofts Platform SDK.

Then add the path for the file to the include paths for the project in question..

receiving power management events in a service

Hi,

Please tell me how a windows service can recieve events (especially power management ones). There was a function RegisterSysMsgHandler() as part of OneNow initiative which was supposed to allow a service to listen for window events.. But I can't find the documentation for that function anywhere on the web. Is there a new function by some other name which achieves the same thing?

Thank you,

Dilip

In the structure SERVICE_STATUS.dwControlsAccepted set SERVICE_ACCEPT_POWEREVENT.

In the beginning of your service main routine use ::SetServiceStatus() to specify the controls accepted (i.e. handled) by your service (i.e. handler routine).

In your service handler routine add a case to handle SERVICE_CONTROL_POWEREVENT.

Will only work for Win2K and up (i think).

First Take a look at RegEnumKey
RegEnumKey look Like this

LONG <code>RegEnumValue</code>(
  HKEY hKey,           <font color="green">  // handle to key to query </font>
  DWORD dwIndex,     <font color="green">    // index of value to query </font>
  LPTSTR lpValueName, <font color="green">   // value buffer </font>
  LPDWORD lpcValueName, <font color="green"> // size of value buffer </font>
  LPDWORD lpReserved,  <font color="green">  // reserved </font>
  LPDWORD lpType,      <font color="green">  // type buffer </font>
  LPBYTE lpData,      <font color="green">   // data buffer </font>
  LPDWORD lpcbData    <font color="green">   // size of data buffer </font>
);

Now Some Code Snippet

char szNameOfKey[200];<font color="green">//Buffer  </font>
DWORD dwBufferSize=200;<font color="green">//Buffer Size </font>
DWORD dwIndex=0;
CStringArray arrOfKeys;

Now Enumerate the HKEY_CURRENT_USER using RegEnumKey

 while(RegEnumKey(<code>HKEY_CURRENT_USER</code>, //
                  dwIndex++, <font color="green">//Index of Key to be Retrive </font>
                  szNameOfKey,<font color="green">//Buffer of Key </font>
                  dwBufferSize,<font color="green">//Buffer Size </font>
                  NULL,<font color="green">//as documented in MSDN </font>
                  NULL,<font color="green">//We don't need this right </font>
                  NULL,<font color="green">//So no need of it </font>
                  NULL)!= ERROR_NO_MORE_ITEMS)
 {
 <font color="green">//add New Found Key to array </font>
  arrOfKeys.Add(<code>szNameOfKey</code>);
 <font color="green">//Restucture the size of Buffer as it modified during  </font>
 <font color="green">//Enumeration </font>
  dwBufferSize=200;
 }

<font color="green">//Now <code>arrOfKeys</code> Hold all the Enumerated Key </font>

Hide & Show Menu bar dynamically

17-Jan-05 14:09

Hi All,

I' m writing a Visual C++ MFC dialog-based program. I added a Menu bar uisng Insert->Resource-> Menu, not by writing code. Then, I tried to show and hide the Menu bar of a modal dialog dynamically.

By writing the following code, I succeed to hide the menu bar.

CWnd* pMain = AfxGetMainWnd();
if (pMain != NULL)
{
CMenu* pMenu = pMain->GetMenu();
while(pMenu != NULL && pMenu->GetMenuItemCount() > 0)
{
pMenu->DeleteMenu(0, MF_BYPOSITION);
pMain->DrawMenuBar();
}
}

But how can I show the menu again? Please kindly help me!

Cheers,
hmc

I think this code illustrates what you need:

void CShowHideMenuDlg::OnShowMenu()
{
// Load and add the new menu
CMenu mMainMenu;
mMainMenu.LoadMenu(IDR_MENU1);
ASSERT(mMainMenu);
SetMenu(&mMainMenu);
}

void CShowHideMenuDlg::OnHideMenu()
{
// Remove and destroy the old menu
SetMenu(NULL);
::DestroyMenu(GetMenu()->GetSafeHmenu());
}
