Hi.

Is there a way to log which process has accessed/changed a file?

I looked at the FileSystemWatcher class, but it dos not tell which process.

Drawing Borders' Corners [SOLVED]

I found the solution Wink | ;)

I'm drawing a gradient border for a control, everything is drawn but corners.
Here[^] is the screenshot, I tried to draw on top left corner but its looking odd.

Rectangle topLeftRect = new Rectangle(0, 0, borderThickness, borderThickness);

Rectangle topRect = new Rectangle(borderThickness, 0, this.Width - (borderThickness * 2), borderThickness);
Rectangle botRect = new Rectangle(borderThickness, this.Height - borderThickness - 1, this.Width - (borderThickness * 2), borderThickness);
Rectangle leftRect = new Rectangle(0, borderThickness, borderThickness, this.Height - (borderThickness * 2));
Rectangle rightRect = new Rectangle(this.Width - borderThickness - 1, borderThickness, borderThickness, this.Height - (borderThickness * 2));



e.Graphics.FillRectangle(new LinearGradientBrush(topRect, Color.Transparent, Color.Gray, 90, false), topRect);
e.Graphics.FillRectangle(new LinearGradientBrush(botRect, Color.Transparent, Color.Gray, 270, false), botRect);
e.Graphics.FillRectangle(new LinearGradientBrush(leftRect, Color.Transparent, Color.Gray, 0, false), leftRect);
e.Graphics.FillRectangle(new LinearGradientBrush(rightRect, Color.Transparent, Color.Gray, 180, false), rightRect);

e.Graphics.FillRectangle(new LinearGradientBrush(topLeftRect, Color.Transparent, Color.Gray, 35, false), topLeftRect);

Listview and tooltip popup for each cell?

syntax28uk28-Feb-09 2:30

Hi All,

I've got a Listview control on a windows forms and it is set to details view, shows full grid lines - so that it looks like a grid. I've three columns in the list view and have 10 rows of data. My problem is, I need a way so that when the user mouse cursor is over a particular cell of data, I want a popup (almost like a tooltip) to be displayed. Once my mouse cursor is removed from over the cell, the popup should automatically close down. Of course, this popup, will have a lot of other prepopulated data within it.

Is this possible with C#, Windows Forms? If so, can you provide some ideas on how I might go about do this? I do see this on some web site, but have never seen this on a windows forms application before.

Many thanks,
Jim

Use ItemMouseHover event of ListView, like this

private void listView1_ItemMouseHover(object sender, ListViewItemMouseHoverEventArgs e)
{
    toolTip1.SetToolTip(listView1, e.Item.Text);
}

or use ToolTipText property of ListViewItem

Thank Xmen, but the tooltip will only show or popup when the user cursor is place over the first column in the listview first. What I want is something that will also popup when the user hovers over different columns.

Thanks,
Jim

Taking a Screenshot - but with performance :(

Hi there,

I'm trying to read a few pixels (200) from my screen, repeatedly. Though what I have found is that
1) the Graphics method CopyFromScreen() has quite a high overhead. Whether I read 1 pixel or 1000 doesn't matter. It's always 33ms, and it doesn't even matter if I keep creating new Bitmap / Graphics objects or reuse the old ones.
2) unmanaged GDI32.BitBlt has exactly the same problem, even if I reuse all hDCs.

So, my question is, is there a fast way to obtain a few pixels from the screen? I already thought about using Direct3d, but I fail using it - and I don't even know if that would perform any better. It keeps throwing a BadImageFormatException at me, and says it's not a Win32 application (Exception from hResult: 0x800700C1). Btw, I don't even want to save to HD. I just want the raw pixels in memory to play around with them. The stuff below was just taken from an example I found.

That's the code I tried to use:

PresentParameters presentParams = new PresentParameters();
presentParams.Windowed = false;
presentParams.SwapEffect = SwapEffect.Discard;
presentParams.PresentFlag = PresentFlag.LockableBackBuffer;
presentParams.BackBufferWidth = 1280;
presentParams.BackBufferHeight = 1024;
presentParams.MultiSample = MultiSampleType.None;
presentParams.DeviceWindowHandle = User32.GetDesktopWindow();

Device device = new Device(0, DeviceType.Hardware, User32.GetDesktopWindow(), CreateFlags.HardwareVertexProcessing, presentParams);
Surface backbuffer = device.GetBackBuffer(0, 0, BackBufferType.Mono);
SurfaceLoader.Save("Screenshot.bmp", ImageFileFormat.Bmp, backbuffer);
backbuffer.Dispose();

Any hints on a quicker way to read a few pixels, all in one horizontal line, would be appreciated Smile | :)

I don't know. You may need a Windows API function.

I did try Windows API. GDI32.BitBlt, which performs just as badly.

1. Wrong forum.
2. What is ASP textbox? Did you mean "asp:textbox" thing? If yes then rush to nearest book store.

In Page_Load create an instance of TextBox and add it to Page.Controls:

TextBox txt = new TextBox();
