Hello
Looking at different examples online, it all says the lpBuffer parameter has to be
a LPVOID (LPSTR).
Is it possible to allocate a fixed memory buffer like a,
char pBuffer[512];
In that case do i need to call LocalFree() function?
Can anyone show me how to use that? I wanted to make sure i allocate the memory on compile time rather than on run time.

If you don't set dwFlags to include FORMAT_MESSAGE_ALLOCATE_BUFFER you can allocate the buffer yourself on the stack and not call LocalFree() to release it.
On another hand, how do you know the message will fit into 512 bytes?

I agree with Nemanja Trifunovic.In accordance with his idea,you can refer to the following codes:
LPVOID lpMsgBuf; <br />
FormatMessage( <br />
FORMAT_MESSAGE_ALLOCATE_BUFFER | <br />
FORMAT_MESSAGE_FROM_SYSTEM | <br />
FORMAT_MESSAGE_IGNORE_INSERTS, <br />
NULL, <br />
GetLastError(), <br />
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf, <br />
0, <br />
NULL <br />
); <br />
MessageBox(NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION); <br />
<br />
LocalFree(lpMsgBuf);

Producer-consumer problem on a circular buffer. Multiple producer and multiple consumer threads may be running concurrently using either semaphores or a combination of mutexes and condition variables.

Yes and the kernel is preemptive, and today is the 'dumb people making pointless posts' day.

I would actually even try a SRW Lock, but then since this case might require FIFO (SRW Locks are not FIFO, and the algorithm isn't "fair" either), a CRITICAL_SECTION is the best option. I'm assuming that this is all happening within the same process, but if not, you could use a Mutex.

A program (server) that reads a single number as input, searches the file for a line with the input integer as the serial number and writes the proverb or the short quotation as output. If the number is not found in the file, the program should return some default message of your choice.
A program (client) which asks the user to enter a number and outputs the same
Is it possible to connect the client and the server programs with a named pipe so that the client can display the output from the server program.

Yes, it is possible.

Hello,
I have a question concerning VC++ and columns and checkboxes. This I'm assuming
is a common hurdle to jump when building a GUI.
I want to to have a graphical interface that shows a list of columns.
The first column, describes the item the following columns could A,B,C etc but are
"checkbox" columns that will profile the item in the first column.
I went down the merry path of looking into CListControl in MFC that has a column
and by setting the style to CHECKBOX you can have a single item with one checkbox,
nice to know. Not what I need.
Datagrid looks like that is what I need, but I dont see this in MFC.
Can somebody point me to an example and even tell me if this is what I need.
Thanks in advance,
Garyc

You can use the subitem-image to display the checkbox. Just copy the state-images to the official image-list, and react to mouse-click on the subitem-image to change the checkbox.
I have implemented this on CGridListCtrlEx - Grid Control Based on CListCtrl[^]

I'm not sure i understand you correctly but in resource editor, give the "Group" (WS_GROUP) style to the first radio button in both of your "radiobutton-sets".

Ok, let's go step by step, did you create your dialog with the resource editor in Visual Studio?
