Hello,

I think you should create youre one progress bar.
Like this article shows:

Based on that example, you should only have to add one more Color (LimitColor) and one more int (LimitValue) property to do the trick.

In the OnPaint method of the ColorProgressBar class you then have to change the first lines from:

//
// Calculate matching colors
//
Color darkColor = ControlPaint.Dark(_BarColor);
Color bgColor = Color.White;//ControlPaint.Dark(_BarColor);

To:

Color ActColor=_BarColor;
if(_Value>LimitColor)
{
    ActColor = LimitColor;
}

//
// Calculate matching colors
//
Color darkColor = ControlPaint.Dark(ActColor);
Color bgColor = Color.White;//ControlPaint.Dark(_BarColor);

Hope to help you!

All the best,

Martin

It is not working

Without seeing the actual line of code you are using, watch your brackets. Especially if you are doing a calculation and then putting the result into an int. You might be casting one of the operands rather than the result (which might still be considered a decimal).
Or there might be another implicit cast going on that you are missing.

int i = (int)mydecimal;

Be aware that this will truncate (round down) so 1.9999 will become 1 not 2. Use Math.Round for actual rounding.

Problem in Getting the exact char[] data from C++ to C# String

Hi,
I am facing a problem while accessing a C++ dll from C# code.
Following is my C++ structure I am using...
typedef struct
{
LONG lPaBitNr;
UCHAR szPaAbr[8];
} AudioUnit_T_DataType;

and corresponding structure I am using in Dot Net is:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct AudioUnit_T_DataType
{
public int paBitNr;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=8)]
public String paAbr;
}

and following is my declaration of the function of C++ dll.
[DllImport("MyLib.dll", EntryPoint = "MyFunc")]
public static extern int MyFunc(
[MarshalAs(UnmanagedType.AsAny)]
object key,
[MarshalAs(UnmanagedType.AsAny),In, Out]
object data,
int size
);
size is the respective size of the structure (no of bytes to copy in data object)

When I call the MyFunc function with object data as AudioUnit_T_DataType structure,, i got all the data but I always loose the last character (8th) in the String paAbr.
i.e. suppose, the value of szPaAbr[8] was "abcdefgh"
then, after the call of MyFunc function, i got "abcdefg" value.. 'h' is lost (might be it is replaced by null character...)
What should I do to overcome this issue.
I dont want to change the lenght of array from 8 to 9.

Any help is appreciable.

Even though I'm not at a PC with .NET installed, I can think of 2 possible solutions:

System.Runtime.InteropServices.Marshal.PtrToStringAnsi()

or

CharSet = CharSet.Unicode

thanks for the quick response.
But both the solutions will not work,, as on C++ side, we donot have null terminated string,, we have array of 8 characters. and on C# side, we want to get that in a string.

Also, the Unicode solution is not working.

OK - this is what you have got with DateTime already. The DateTime class is a wrapper around an internal representation of the date/time. The methods for displaying date and time are there for your convenience.

Yes, when you print it out it will be using the ToString() method, but this is just to cast it into a format for you to use/print out. It does not change the internal representation at all.

the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

Deja View - the feeling that you've seen this post before.
