No, it is not common to all. That would be one amazing utility since there are at least 54 different OSs[^]

Yes they are so many operating systems. But you can find the kill command in OS's like unix

Of course, but re-read the original post again. It was whether KILL was supported on all OSs not whether it was supported on Unix.

Then we will be living in a new planet if it can be supported by all OSs.

In my MFC MDI application I'm trying to add some new entries to the "Help" menu.
I have an existing menu item with ID_HELP identifier, this works fine, and displays the correct message in the application status bar (as specified under ID_HELP in the String Table).
If I add a new menu item, say ID_HELP_NEW, and a new string in the String Table under ID_HELP_NEW - you'd expect that string to show in the status bar when you hover over the new menu item, yes?
However, regardless of my string table entry the application shows "Switch to the previous document window" in the status bar for all new entries on the help menu. Seems to be something automatic done by MFC. (I've deleted my "Window" menu, if that makes any difference).
Anyone have an inkling what isgoing on here?
Cheers,
Dan

Seems I was accidently reusing one of the default resource IDs, hence I was getting the wrong message. If I change my new resource ID to something lower, everything works fine!

i'm using a list box and list control to displaying my data which retrieve from my database in different dialog and now i would like to save the data that i retrieve in a .txt file..
i wish to use CFileDialog.DoModal() to save my file...
can anybody give me some guide on how to transfer my data in list box or list control to a txt file?

if you are a MFC user, the following should help :
CString str;
ofstream file("file.txt");
CListBox* pLB = GetDlgItem(IDC_LISTBOX);
int NbLines = pLB->GetCount();
for (int i = 0; i < NbLines; i++) {
pLB->GetLBText(i, str);
file << (LPCTSTR)str << '\n';
}

Here is the CFileDialog part only, the other part you asked was already answered....
static char BASED_CODE szFilter[] = _T("Text Files (*.txt)|*.txt||");
CFileDialog m_ldFile(FALSE,_T(".txt"),_T("file.txt"),OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, szFilter);
if (m_ldFile.DoModal() == IDOK)
{
CString strPath = m_ldFile.GetPathName();
}

You don't initialize choice in your menu function. If you enter character data when scanf is expecting an integer (the "%d" format), scanf will stop scanning the input, and not set the choice variable. This means that your menu function will return a random value if you enter character data. Note that this random value could include one of your valid menu values of 1 through 4.

How about some error checking:
int done = 0;
while (! done)
{
printf("\nEnter choice (1-4): ");
done = scanf("%d", &choice);
}
return choice;This is hardly foolproof, and may not even work, but it might give you a foundation to build upon. An alternative is to use getch() to get each character as it is typed. If it is a numeric character, proceed. Otherwise, indicate problem and ask for another character.

What's wrong with:
int menu( void )
{
int choice;
do
{
printf("\nEnter choice (1-4): ");
choice = _getche();
} while (choice < '1' || choice > '5');
return choice;
}
void main( void )
{
int choice;
while ((choice = menu()) != '5')
{
switch (choice)
{
case '1':
...
}
}
}

Well its like it does not want to accept any input whether text nor digits
-oam-
there might be something missing because it does read input and i can't figure it out
|

|

Well i used the other method which i found it simpler even though longer that the one you suggested.
printf("\nEnter choice (1-4): ");<br />
valid = 0;<br />
while( valid == 0)<br />
{<br />
fgets(iobuf,sizeof(iobuf),stdin); <br />
len = strlen(iobuf)-1;<br />
iobuf[len] = 0;<br />
valid = 1;
for(i = 0; i < len; i++)
{<br />
if( !isdigit(iobuf[i]))<br />
{<br />
printf("\nPlese enter numeric digits only (1-8):");<br />
valid = 0; <br />
}<br />
}<br />
break;<br />
}<br />
choice = atoi(iobuf);<br />
<br />
scanf("%d", &choice);
return choice; <br />
}
Thanks anyway.

in my keyboard hook dll i have used a global variable in all functions of that dll. I get value of that variable when control is in dll calling application. but if control is in another application (notepad or word) it won't get the global variable's value.
|

Global varible does NOT mean global concerning multiple processes!!
That global just means then you can access it from every function of ONE process.
If you want to access the variable from multiple processes then you have to share it!
To make it more clear:
The DLL file format (called PE file format) consists of sections. These section can have different settings. You code normally uses a section called .text, and the global variables use .data.
When a DLL is attached to a process, the sections are checked whether they contain data or code, and weather they sould be shared accross the whole system.
If sharing is not used, then the .text section is loaded and initialized by the code from the DLL file, but the .data section gets NEW memory, which is then initialized by the main function of the DLL file.
That would mean, that every process with the DLL attached to it, there is a completly new .data section which has different physical addresses in your RAM.
So when you want to share such a global variable over many processes, then you need to add a new shareable section or modify the whole .data section to make it shareable (which is not very reasonable).
To create a new section use this code:
#pragma data_seg( ".share" )
HANDLE hFileHandle = 0;
#pragma data_seg()
#pragma comment( linker, "/SECTION:.share,RWS" )
Don't try it, just do it!
