Does anyone know of a method to return a list of files that a current executable is using? I will be doing this in C# but would like to get some input from anyone. Thanks in advance.

What do you mean by 'associated files'? File extensions associated with an application? Or files open by the app in given moment?

Any supporting files the executable requires to run.

In this particular case, no Smile | :)

If you have unmanaged .exe - like the ones produced by VC6 - you can use depends.exe to check which .dlls program is explicitly linked to. However, program may load any .dlls at runtime with LoadLibrary and link to their functions with GetProcAddress.

Managed assemblies created by C# are totally different story.

I guess I was looking at the Bigger picture, not just the application that I am going to be working on. I understand there are many million different ways to do things, especially when different languages are feasible for an operation, I guess it was more of a philosophical statement really.

adding functions to submenus

Rajveer27-Mar-02 2:12

I noticed that when you make a new submenu for any of the menus, you can add a function for COMMAND or UPDATE_COMMAND_UI
What do these two things mean?

Re: adding functions to submenus

Tomasz Sowinski27-Mar-02 2:30

Tomasz Sowinski

COMMAND handler is called when user clicks on the menu item - you put the real work there.

UPDATE_COMMAND_UI is called in response to WM_INITMENUPOPUP, just before displaying the menu. It gives you the opportunity to enable/disable/check/change the text of menu item.

If your menu item is always enabled, you don't need UPDATE_COMMAND_UI.

Not sure if I've understood what your saying properly, but ON_COMMAND is where you tell your class what to do upon receiving that command message and ON_UPDATE_COMMAND is where you tell your class what to do when that menu needs to be updated (in your AFX_MSG_MAP part of your message map)

E.g.:

<br />
  ON_COMMAND(ID_OPTIONS_FONT, OnOptionsFont)<br />
  ON_UPDATE_COMMAND_UI(ID_OPTIONS_FONT, OnUpdateOptionsFont)

Heres the MSDN info:
ON_COMMAND, ON_UPDATE_COMMAND_UI

Thanks,

this is exactly what I do.

The problem is that modeless dialog stays always over its parent dialog, even when it is not focused. How to prevent this behaviour.

Thanks again
Stefan

Maybe you can get the effect you want by making the desktop (GetDesktopWindow) the parent of your modeless dialog.

Set Default Printer

jerry0davis27-Mar-02 1:19

27-Mar-02 1:19

My app creates html fire reports when it surprisingly enough detects a fire. Wink | ;)

I need the enum all the printers and print this html fire report inside a CWebBrowser2 controls on all the connected printers. I do this by setting the default printer, and printing, and then setting the default printer again etc.

I use the SetDefaultPrinter command. This worksd fine. The problem is though that it only works in Win2000+. MSDN says that I should use the following code on < Win2000

C++

// read PrinterPorts section from win.ini
        // returned string should be of the form "driver,port,timeout,timeout", i.e. "winspool,LPT1:,15,45".
GetProfileString(TEXT("Windows"),TEXT("Device"),_T(",,,"),m_szName, COUNTOF(m_szName));
WriteProfileString(TEXT("Windows"),TEXT("Device"),pszPrinterName ));
        // Notify all open applications of the change. Note, only applications that handle the message will recognize the change.
#if WM_WININICHANGE != WM_SETTINGCHANGE
        // Old message type; for windows 95
SendNotifyMessage(HWND_BROADCAST,WM_WININICHANGE,0,(LPARAM)szWindows);
#endif
        // New message type
SendNotifyMessage(HWND_BROADCAST,WM_SETTINGCHANGE,0,(LPARAM)szWindows);

I can't seem to get this to work Cry | :((

I'm not quite sure what I should set szWindows to....

Can anyone help please? Thanks Smile | :)

Multithread (Client Server) Problem (Repost)

hkl27-Mar-02 0:41

Hi,

Can anyone please give me any comment or solution to this situation??

In my program, I've used multithread (many clients) to send message to one thread(Server). However, I realized that only the first client can get access to the server from start to end, other clients are always blocked. Can anyone help me to solve this problem, so that all clients can access the server??

The following is the code of the server:

if ( svrSocket.Accept(socket))
AfxMessageBox("Socket is created Succesfully");

while (...)
flag = socket.Receive(buff,sizeof(buff));
....

Please HELP! Thank you!! Confused | :confused:

If you have the server thread processing the requests for one client in a tight loop, it can't accept other connections.

Execution in this thread blocks until Receive can get (sizeof(buff)) bytes of data. You should probably use CAsyncSocket; it would probably meet your requirements better.
