Hello!
I'm kind of new to the world of C# and have a little query...Is there some way to manipulate/store/use 256 bit int/float/long so that finally a calculator for those 256 bit values can be made? I know theres the decimal datatype for 128 bits so is there a way for 256 bits too? I have got a vague idea about using a link list and that many byte nodes but are there any other means?
Thanks beforehand for time and help...

Use a BitVector or BitArray. There really need to be better class of this.

Thanks...but could you help me out some little more and tell me howwww exactly to divide that 256 input into those 2 128 bit decimals? I mean the problem facing me is this: I take a string input (readline) and then have to convert that to some numerical form to perform those mathe operations...but to do that I have to have some container, a datatype big enough to hold that converted 256 bit value first right?...so how do I know how and from where to break that converted string input into 2 decimals actually during conversion? I do hope I haven't muddled this up...so anything possible?

Hello there ...
Can anyone help me finding a REAL File / Directory TreeView with CheckBoxes like
it can be found in (for example) the System Backup Tool of Windows 2000 or
maybe like the one in R-Studio ??
I tried to make this with the integrated TreeView and the CheckBoxes but they can't
get grey if only some subitems are checked.
I am looking for a complete component which is not included in the .NET but
somewhere in Win32 )
Can anybody help me ?

MS Office
open your favourite office product, right click on the toolbar, select customize, in the Commands tab select All Commands, drag the command with the icon you want onto a toolbar, now right click the button on the toolbar and select Copy Button Image, now go paste it into your favourite image editor.
[disclaimer] of course you should not be using these icons for commercial applications

It is rather a simple problem (it looks like that).
Once I set the first item visible in a comboBox (comboBoxName.SelectedIndex = 0)
I notice a difference between the comboBox behavior in Windows 2000 and Windows XP.
In Windows 2000 the selected item is visible in the comboBox (it works fine) but in Windows XP the selected item is visible in the comboBox and it is also HIGHLIGHTED (MARKED).
How to make it just visible (like in Windows 2000) and NOT HIGHLIGHTED?
Thanks for help in advance.

Hi, I have created my own control that inherited TextBox.
I override the OnValidating event to check the text against database. The problem is that this happens everytime I leave the control, even if I click on a button which is not the desired behaviour. I tried to set "causes validation " property on the button , but this does not have effect. The only thing that make a change is when I set "Causes validation=false" on my control, but then this event doesn't fire at all.
Help please,
MitDej

hi,
i want to know any method to implement popup menu in C#?
any help for starting?
thanks,

Start with a form, and set the BorderStyle to None.
Remove the WS_POPUP style bit, and add the WS_EX_PALETTEWINDOW style:
int nStyle = GetWindowLong(this.Handle, GWL_STYLE); nStyle^=Win.User.WS_POPUP;
nStyle^=Win.User.WS_POPUPWINDOW;
SetWindowLong(Handle,GWL_STYLE,nStyle);
int nExStyle = GetWindowLong(this.Handle, GWL_EXSTYLE);
nExStyle|=WS_EX_PALETTEWINDOW;
SetWindowLong(Handle,GWL_EXSTYLE,nExStyle);
This is needed because otherwise the active form loses focus when focus is on your popup, which is not good.
Grab the mouse capture with SetCapture() when the mouse is outside your menu, and release the capture with ReleaseCapture() when the mouse is inside your menu (so that any contained controls can get mouse messages). Close the popup when a MouseUp event is recieved and the mouse coordinates are outside of the form's bounds. You will also want to close the popup when it recieves a WM_APPACTIVATE message where the app being activated is not your own.
HTH!

Yes.
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int Index, int NewLong);
[DllImport("user32.dll")]
private static extern int GetWindowLong(IntPtr hWnd, int Index);
readonly int GWL_STYLE=(-16);
readonly int GWL_EXSTYLE=(-20);

A couple more useful API declarations:
[DllImport("user32.dll", EntryPoint = "AnimateWindow")]
private extern static int AnimateWindow(IntPtr hwnd, int dwTime, AnimateWindowFlags dwFlags);
internal enum AnimateWindowFlags
{
Hor_Positive=0x1,
Hor_Negative=0x2,
Ver_Positive=0x4,
Ver_Negative=0x8,
Center=0x10,
Hide=0x10000,
Activate=0x20000,
Slide=0x40000,
Blend=0x80000
};

For a simple menu you can add a ContextMenu to your form.
If you want it to pop up when you like, not when the user right-clicks the form, use the TrackPopupMenu function:
[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern bool TrackPopupMenuEx(
IntPtr hmenu,
int fuFlags,
int x, int y,
IntPtr hwnd,
IntPtr lptpm);
