if what u want is to run the exe from the clicent, use ShellExecute.
ShellExecute( 0, _T("open"), _T("c:\\WINDOWS\\system32\\calc") ,0,0,SW_SHOW);
un the place of c:\\WINDOWS\\system32\\calc, put the full path of ur exe.

Run your Socket Server Program on CMD line.. and (If you Know, or Idea about sockets) you have to to create a client program and connect to ip of your computer system and post at which socket server is listening.
if you don't know the ipaddress of your computer you can use loopback ipaddress i.e. (127.0.0.1)

vansmiles wrote: convert numbers to words
Is it the strings you mean when you say words.
If affirmative, there is a function itoa() that can be used to do this.
If you mean a DWORD value:
A DWORD value is an 32 bit unsigned integer
If WORD:
A WORD is a 16 bit unsigned integer.

This is a common task ( actually, it's a common homework task, is this homework ? )
Think about what you want to do. Think about how your brain processes it. Then think about how to reproduce that in code.

Nah, that'll never work. You're asking the OP to do something many recent posters here can't. You asked for it three times 
I have some VBA code for generating page footers in Excel which includes a page number in Roman numerals, if that's any help ...

Are you wanting

Ladies and gents,
We have a small suite of programs that automate sending recorded voice audio files to a user provided e-mail address. In the next version, we would like to import the user's Outlook or Outlook address book details rather than having duplicate e-mail address books on the system. Can someone point me to an easy way to do this, preferably in C++?
Regards,
Steve

Hi Steverty,
This was a code that we created for some of our application. Use it if it seems useful to you...
_ApplicationPtr pApp;
_ItemsPtr pItems;
MAPIFolderPtr pFolder;
_ContactItemPtr pContact;
HRESULT hr;
try
{
hr=pApp.CreateInstance(__uuidof(Application));
if (FAILED(hr))
{
MessageBox("Unable to instantiate Outlook.",
"Outlook Error",MB_OK);
return 0;
}
if (true)
{
pFolder=pApp->GetNamespace(_bstr_t("MAPI"))->
GetDefaultFolder(olFolderContacts);
if (pFolder==NULL)
{
MessageBox("Could not find default contacts folder.",
"Outlook Error");
return 0;
}
}
else
{
pFolder=pApp->GetNamespace(_bstr_t("MAPI"))->PickFolder();
if (pFolder==NULL)
return 0;
if (pFolder->GetDefaultItemType()!=olContactItem)
{
MessageBox("Select folder is not a Contact folder.",
"Outlook Contacts");
return 0;
}
}
pItems=pFolder->GetItems();
if (pItems==NULL)
{
MessageBox("Unable to get Contact Items.","Outlook Error");
return 0;
}
pContact=pItems->GetFirst();
Somethings seem HARD to do, until we know how to do them.

I have an mfc app that is behaving badly - exhibiting random lockups. It might be the OS, but I don't think so The hang appears to happen when I am leaving a dialog.
I have two styles of leaving a dialog, and based on what I have read in the MS doc, both should be okay. Style 1:
class::OnClickExitBtn()
{
// release all dialog resources.
EndDialog(IDC_EXIT_BTN);
}
Now, in the MS doc, it states that EndDialog sets a flag in the message pump such
that the dialog will exit. Of note is that it will not process any further messages.
Style #2 is:
class::OnClickExitBtn()
{
// All allocated resources in this class released in destructor.
EndDialog(IDC_EXIT_BTN);
}
Style 2 simply moves everything to the destructor. I thought this had cleaned up the hangs, but one just happened again.
So, what is the correct exit procedure from a dialog with allocated resources, timers, etc? Any practical experience to shed some light on this? A past project was very suspicious of SetTimer and avoided it like the plague - using a thread to generate an application message....
Thanks for your thoughts...

I've used SetTimer extensively, and not had it cause the problem you describe. The reason most people have problems with it is that they expect it to be accurate. Windows' handling of WM_TIMER messages is such that they don't occur at the interval you expect. BTW, you don't need to issue a KillTimer() when you exit your dialog.
Rather than deallocating things and releasing resources in the destructor for my CDialog objects, I usually override PostNcDestroy() for that sort of thing. This seems to match up better with initialization performed in an OnInitDialog() override. It also works better when you re-use a given CDialog-derived object.
Software Zen: delete this;

I agree that the SetTimer can be wildly inaccurate, but for me, I just need the periodic event. I also concur with what you say about timer cleanup. I'll do some more reading on the PostNcDestroy method... maybe something is there.
Thanks

Gary - one other question - reading about PostNcDestroy, MS says, "Derived classes can use this function for custom cleanup such as the deletion of the this pointer."
Now, I only use the dialog via .DoModal(). Based on what I've read, I would only need to worry about this if I had done a Create operation...
Sorry, grasping for any kind of memory or resource leak....

The only time you're going to use delete this; is if you're not deleting the MFC object somewhere else. I've only used this in rare cases, where I had a modeless dialog that I wanted to destroy its own MFC object when the dialog closed. If you're using DoModal() then that's not the case.
BTW: Don't mind my sig .
Software Zen: delete this;
|
|
|
|

Ah yes, I recall reading about when you delete and when you don't - I use domodal almost exclusively, so I'm okay there.
Hadn't even noticed the sig, but then, I like it.

Any resources that are associated with the HWND (such as timers) need to be cleaned up while the window still exists. THerefore, the destructor is the wrong place to clean up times since the window is already gone by the time the C++ object is destroyed.

hi
i wanna use *.exe file such az static library.
a static library included in my exe file, so i wanna my exe file involve another exe file(with out any source code from second exe file) and can run second exe file in my exe file.
it can be used to check authentication of user to use an unknown exe file.
can any one help me?
|

You can't "use" another exe as a static library. If the other exe exposes automation interfaces, you can make calls in it (or if it is a COM server/service). Otherwise, you can call it using a system call. The first case is not statically bound, and the system call is not bound at all.

I have an app now that takes input from a COM port and would like to add the ability to take input from a USB device such as a keyboard, barcode scanner, or other device.
I connected a barcode scanner to my machine and it looks like an HID to the machine - specifically a USB keyboard. I went into the HKLM\System\CurrentControlSet\Control\DeviceClasses registry entry and removed all the entries from there. I then plugged this scanner in again and noted the SymbolicLink values for the registry entries created.
I have another application that talks directly to USB printers, and to talk to them, I do a CreateFile with the SymbolicLink values from under the DeviceClasses registry entry. This works just fine, and I get back a valid handle.
When I do the same thing for this USB barcode scanner's entries, I get INVALID_HANDLE_VALUE back from CreateFile for each one.
I need to be able to differentiate input from the USB barcode scanner and a regular keyboard, since I can take input from the keyboard also.
Thanks for your help!
David

I have about the same problem.
Did you find a solution yet?
Allso, I'm searching how you can capture the barcode-imput while you don't allow it to be send to the active application (normally, when you have e.g. word open, the barcode-number is send as trext to the screen). I want the barcode number to be available without it being send to Word...
How can I do that?
Thanks.

Environment is Visual C++ 2003 Standard Edition.
According to MSDN concerning the Properties view in Visual Studio Link[^]
Overrides
Lists all virtual functions for the selected class
and allows you to add or delete overriding functions. However, I have a class that derives from a class that derives from CObject. The object that derives from CObject has mostly virtual functions. However, if I click on any class, I cannot see those virtual functions in my properties view/overrides section. I only see the overrides for CObject regardless of the class selected.
Is it incorrect to expect my derived class' virtual functions to appear in the overrides section?
