The problem you'll have is that unless you're moving your object exactly along the X or Y direction, or at 45 degrees, you won't have an integer number of pixels in each direction. What you need to do is something like :- float ratio = (float)(y2 - y1) / (float)(x2 - x1); // note : this is dY / dX, not as in previous post int step = (x2 > x1)? 1 : -1; float newFloatY = y1; int newX = x1; for (int loop=x1; loop!=x2; loop+=step) { newX++; newFloatY += ratio; int newY = (int)(newFloatY); // position object at newX, newY... } You'll need to modify it if you want to move by 1 pixel in Y, and cope with special cases like moving exactly horizontally or vertically, but those are "left as an exercise for the reader"... :) There are three kinds of people in the world - those who can count and those who can't...

This code worked fine for columns, it can also be slightly modifed to fit for rows: tableLayoutPanel1.ColumnStyles.Clear(); int numOfColumns = 4; tableLayoutPanel1.ColumnCount = numOfColumns; for (int i = 0; i < numOfColumns ; i++ ) { ColumnStyle cStyle = new ColumnStyle(); cStyle.SizeType = SizeType.Percent; cStyle.Width = 100 / numOfColumns; tableLayoutPanel1.ColumnStyles.Add(cStyle); }

That may have a problem if called from a different assembly? I guess stick with System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName. I suppose might System.Windows.Forms.Application.ExecutablePath call that.

In the System.Net.NetworkInformation namespace, there is a Ping object, that can ping either an IP address, or a host-name (the name of the computer). Use the Ping.Send( string ) or Ping.Send( IPAddress ) methods and get a PingReply object with details about the host or address pinged. See How to ping a hostname/ip using ASP.NET 2.0 and C# .NET[^] for an example of using the Ping and PingReply objects.

You need to look at the existing picture boxes and if they overlap with your new picture box then move your new picture box. Detecting an overlap is fairly simple. Each control can give you its Bounds[^], which is a Rectangle[^] object. The Rectangle structure has an IntersectsWith[^] method which will return true if the rectangles intersect (overlap) with each other. For example: bool isOverlapping = firstPictureBox.Bounds.IntersectsWith(secondPictureBox.Bounds); Developer Day Scotland 2 - Free community conference Recent blog posts: *Throwing Exceptions *Training Developers * Method hiding or overriding - or the difference between new and virtual

Try responding to the WM_DEVICECHANGE[^] window message. A WParam value of DBT_DEVICEARRIVAL[^] should indicate a new cd/usb drive. Will probably only work if you have auto insert notification turned on for the drive. [Edit: Oops, should have hit refresh before posting. I agree with Luc] Simon

That is easy by using recursion. Combine each letter with all combinations of the letters after it: All combinations in "ABCD" is: Combine "A" with each of all combinations in "BCD". Combine "A" with each of the letters in "BCD". Combine "B" with each of all combinations in "CD". Combine "B" with each of the letters in "CD". Combine "C" with each of the letters in "D". Despite everything, the person most likely to be fooling you next is yourself.

right. :doh: Luc Pattyn [Forum Guidelines] [My Articles] Fixturized forever. :confused:

You can try out this. In Server, 1. Read the image from the file. 2. Save the image onto a MemoryStream object. 3. Get the buffer from the MemoryStream using GetBuffer() method, this method will return the bytes from the memory stream. Now you send this byte array to the client. Now In Client, 1. Create new MemoryStream object and write the byte array received from server onto the MemoryStream. 2. Create new Image object from the MemoryStream using Image.FromStream() method and use this image object in the PictureBox. Do more work Make more mistakes Learn more things

When you check what key has been pressed, you can also check if any special keys are also pressed (like Ctrl, Shift) So to check for Ctrl+F: void myEvent(object sender, EventArgs e) { if(e.Key == F && e.Ctrl) { } } Or err, something like that anyway.

Of course you can ... alot of ways to do so and WMI is one of them ... use the System.Management namespace to help you so ... as follows: ArrayList list = new ArrayList(); using (ManagementObjectSearcher DiskSearch = new ManagementObjectSearcher(new SelectQuery("Select * from Win32_LogicalDisk"))) { using (ManagementObjectCollection moDiskCollection = DiskSearch.Get()) { foreach (ManagementObject mo in moDiskCollection) { list.Add(mo["Name"].ToString ()); MessageBox.Show(mo["Name"].ToString()); mo.Dispose(); } } } Dont forget to add a reference in your project to System.Management dll and you will get all the drives .. for more properties go to this link to get them (other than the Name property used here): http://msdn.microsoft.com/en-us/library/aa394173.aspx[^] Enjoy !
