I had another question about this issue, but I didn't ask properly, so here I go again! I'm sending a file by sending it in chunks. Right now, I'm playing around with different numbers for the size of that chunk, to see what size is the most efficient. When testing on the localhost, any chunk size seems to work fine. But when I tested ...
I'm trying to debug a memory leak in a printer driver. I'm pretty sure it's a resource leak, not just a plain memory leak because analyzing heap with !heap -s in windbg doesn't show any increase. How do I monitor other kinds of objects with windbg? Number of GDI objects and open handles is not growing either, so what could it be? The...
I'm trying to send an int array through Winsocks. I might be wrong, but I'm pretty sure only a char* is supported so I'm kind of stuck on how to do this properly. There are also problems with little/big edian, so what would be a good way to do this? I've already asked a question of converting int array to char but it was recommended to s...

I recently acquired a Metrologic Barcode scanner (USB port), as everyone already knows it works as a keyboard emulator out of the box. How do I configure the scanner and my application so that my app can process the barcode data directly? That is, I don't want the user to focus on a "Text field" and then process the data when the KeyPre...
Here's what I want to do. I want to present a file explorer, and allow the user to select files, and list the selected files below. (I then want to process those files but that's the next part) For example, the way CD Burning softwares work.

Hi I need a utility to close server socket handles open by the process, on windows. I cannot use tcpview as it does not close the server socket (ESTABLISHED state). Process explorer comes close with its handle list and "close handle" option, but it only gives the handle path (like \Device\Afd) and if application has open many such socket...

We need to switch users without logging off so we can remotely administrate a PC running with a limited user that will disconnect from the VPN if the user logs off. I've got this working by killing the explorer process and then running explorer.exe with the administrator user credentials as the following code shows: private void bt...
When a volume is attached to file system, on Windows, the Window explorer detects the volume and refreshes automatically. I wonder the technique. How do an program(include device driver) get the notification? -Of course, it doesn’t mean a polling. I want to get an event(or a message). I would like to get the notification when a network...
(Using Windows 2000 and 2003 Server) We use forfiles.exe to delete backup .zip files older than n days, and it works great (command is a bit like below) forfiles -p"C:\Backup" -m"*.zip" -c"cmd /c if @ISDIR==FALSE del \"@PATH\@FILE\"" -d-5 If a .zip file fails to be created, I'd like to ensure that we don't end up with 0 .zip files in...

For this I have configured a "FILE:" printer port which works very nicely but asks everytime for the file name to use. Unfortunately "FILE" is not a very descriptive word when trying to use a search engine :( I...

I know how to use EventLog, EventLogEntry and EvenLogEntryCollection to open and read a server's event log, but an EvenLogEntryCollection can contain ~300.000 events, and it wraps around continuously (and very fast), so I ...
I'm using Windows API's CreateFile and SetCommState functions to open a number of serial ports to read and write from, selecting ports using this notation: \\?\COM1 I've been logging performance closely, and for some odd reason the CreateFile call takes about as much time as the SetCommState calls do (about 4.1 seconds). I find t...
I'm trying to implement a control similar to Firefox's Rich List Box: However, I can only find the XUL implementation of this control, and I don't want to have to include a XUL processing engine in my application just to get a cool looking listbox. I've been trying to implement one on my own by customizing MFC's CListBox control, but...
