Hi Luc,
I use no borders form. I created a PictureBox as a resizing point and with mousemove, mouseup, mousedown events it works fine.
Thank you for help.

Hi, I am learning managed c++ in visual c++ 2005 express, the code below will find files starting on letter x, my question is how can I copy them to some directory ex. C:\\XXX\\y ?. Thx
<br />
DirectoryInfo^ directory = gcnew DirectoryInfo("C:\\Documents and Settings");<br />
array<FileInfo^>^files=directory->GetFiles("x*.txt",<br />
System::IO::SearchOption::AllDirectories);<br />
for (System::Int16 i=0; i<files->Length; i++)<br />
textBox1->AppendText(files[i]->Name + "- " + files[i]->Length + System::Environment::NewLine);<br />

Hi,
there is no software interface to the USB bus, as far as your app is concerned you should
talk to the device (possibly connected to the USB), using its driver. That's either a general-
purpose driver (like the one that makes USB sticks and cameras look like a disk), or
a specific one, that comes with your hardware (such as a USB-to-serial or a USB-to-Ethernet
cable, which need a driver).
The above holds true for all kinds of busses: memory bus, IDE, SCSI, ... You ignore the
bus, and address the device that interests you.

When I bought my USB-to-serial cable, it came with a CD-ROM containing a driver.
When I installed it, it turned the port into a regular serial port, I could even choose
the port name (anything, including COMn with n a decimal number), so it shows up
in all serial port enumerations, and all serial apps should be able to use it,
whether HyperTerminal or some .NET based app using SerialPort class.
The app never is aware the USB-based serial port is connected in a different manner, all
the nasty details are hidden by Windows and the device drivers.

sir, how come an empty System::Windows::Forms::Form would need about 10MB memory when launched and then checking it out on task manager/processes?
i somehow find it inefficient? or maybe im just clueless...
now im making a simple app and it easily reached 45MB...
if i strip down all form resources it went down to 35MB...
so i wonder, what if, just the basic form? huh, like shocked 10MB...
kore wa 'normal' deshoo?

This is becase you don't understand who memory allocation works under the .NET Framework. YOu're looking in Task Manager for the size of your application (not your form!) Task Manager is showing you the memory reserved by the .NET runtime (called the Managed Heap), NOT how much memory your application is actually using. When you app gets around to allocating memory for objects, the allocation is made from the Managed Heap where it happens very quickly. If the Managed Heap runs dry (not very likely), the CLR has to go to Windows to get more memory for the Managed Heap, which takes more time.
If Windows start to run low on memory, it can go back to the .NET CLR and ask for memory to be returned, which the runtime will happily do if it's not being used.
If you want to see how much memory your app is actually using, use the Performance Monitor and the .NET CLR memory counters, not Task Manager.

I think I need to add something to the forum guidelines that states that if posts don't make sense, or are generally inane then I will unleash the hounds of mockery. It's like a rockery only with humour.

Oh come on, his post made perfect sense!
Obviously, he opened his window and found that the pane had been programmed-- Err... Wait...
Ok, so he's writing a program to cause pain in windows-- Err, isn't that redundant? Let me try again...
He found a program that runs in a window and can experience pain-- Ahhh, Skynet! Run!
Ok, I give up.

They say, You can share all your pain with friends.
But my dear friend, this "program as program PAIN in window" is really next to impossible to share.
Sorry.
Please take care of yourself.
