If your time measurement doesn't require to be very precise then you can do something like this:

<br />
DateTime starttime=DateTime.Now;<br />
DoWork();<br />
DateTime endtime=DateTime.Now;<br />

The difference between endtime and starttime will show you the duration between two moments.

However, if your measurements need to be precise then I suggest you use Stopwatch Class[^]

What do you mean by "parse a c# code?" Are you trying to parse a file full of strings? Are they fixed-width fields, delimited, do they use CR and/or LF?

How about you check out the documentation[^]?

From the docs: "Provides a base class for CodeDomProvider implementations. This class is abstract." Of course it throws not implemented exception, it's the base class. Follow the provided link, there is example how to parse code.

Hi all,

Is there a C# command for me to insert date into a microsoft access database to record the date down?
I've already set the row to date/time format.

The following is the code I've written:

SQL = "INSERT INTO sent (Date, Message) VALUES ('" + DateTime.Now.Date() + "', '"+strMessage + "')";

However there still seems to be a problem as the Date still could not be recorded down into the database.

Thanks.

Can you be more specific about the problem? Are you getting exception or an error during execution? Also, I suggest you use parameterized queries as they help you to prevent sql injection attacks. See here for more information: SQL Injection Attacks and Some Tips on How to Prevent Them[^]

Use a parameterised query, then you don't have to format the values yourself:

SQL = "INSERT INTO sent (Date, Message) VALUES (@Date, @Message)";

Now add parameter objects for @Date and @Message to the command object.

If you really want to format the values yourself, you use # around dates in Access, you have to format the date in a way that the database understands (ISO 8601 is an unambigous format), and you have to encode the apostrophes in the string values:

SQL = "INSERT INTO sent (Date, Message) VALUES (#" + DateTime.Today.ToString("yyyy-MM-dd") + "#, '" + strMessage.Replace("'", "''") + "')";

Experience is the sum of all the mistakes you have done.

Hi there,

Since the final version will be coded in C# I thought I could just post it here. Any answers on others languages would be great too though.

I'm trying to find an algorithm that will calculate how much two Strings differ from eachother. For example, giving a score from 0-100 based on how much they are alike. I did come across the Levenshtein algorithm, but that wasn't realy what I'm looking for.

For example:
Comparing "markAdress" with "adressMark" should return a high score, since they are much alike.

Kind regards,
~Sph

Hi y'all,

I'm working with a two-dimensional array and i need to randomly select any element from the array at any given time. Is this possible?

Second, from an array of strings, is it possible to randomly select a string value like the System.Random class?

Thanks in advance,

How to send value to report in Reporting Services programmatically ?

8-Nov-07 20:57

In first case just generate two random numbers which are not more then the dimension of the array and use them for indexes to access an element of the array.

In the second case generate a random number not more then the length of the array and access an element with that index

hi i have a reportViewer in my form and a report in reportDesigner named 'Report1.rdlc'.
in my report, i define a parameter that has these properties :
Name = Report_Parameter_0
Data type = String
Promt = 11111111111111
Allow blank value = true
Null = true

and add a textBox to my report in reportDesigner with following properties :
Name = textbox5
Value = Parameters!Report_Parameter_0.Value

and in my form load event that show report i wrote this code to send my value to 'Report_Parameter_0' programmatically :
try
{
this.v_customerOrderCountTableAdapter.Fill(this.NorthwindDataSet.v_customerOrderCount);
Microsoft.Reporting.WinForms.ReportParameter rp = new Microsoft.Reporting.WinForms.ReportParameter("Report_Parameter_0", "Param From Code");
this.reportViewer1.LocalReport.SetParameters(new Microsoft.Reporting.WinForms.ReportParameter[] { rp });
this.reportViewer1.RefreshReport();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

with above information, in runTime, i prospected that 'textbox5' have 'Param From Code' value, but have
'Parameters!Report_Parameter_0.Value' yet.
where does problem and how to send value to reportParameter correctly ?
thanks

Disable/Enable Check Box in property Grid

I require to disable/enable check box in a property grid dynamically at runtime using C# .NET.

I was able to to disable/enable the Check box at runtime. But the problem is If I enable check box dynamically I am no longer able to select the check box. I am using TypeConvertor and UITypeEditor together to disable/enable the check box at runtime.
If I do not use TypeConvertor with UITypeEditor then I am able to select the check box.

Can anyone faced this problem ?

I am using the following Code piece:

[TypeConverter(typeof(myConverter))]
[Editor(typeof(CheckBoxInPropertyGridEditorCapex), typeof(System.Drawing.Design.UITypeEditor))]

public bool ValidForCapex
{
get { return validForCapex; }
set { validForCapex = value; }
}

public class CheckBoxInPropertyGridEditorCapex : UITypeEditor
{
public override bool GetPaintValueSupported(ITypeDescriptorContext context)
{
return true;
}

public override void PaintValue(PaintValueEventArgs e)
{
ControlPaint.DrawCheckBox(e.Graphics, e.Bounds, ((GeneralDimensionClass)e.Context.Instance).validForCapex ? ButtonState.Checked : ButtonState.Normal);
}

}

public class myConverter : StringConverter
{
public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
{
if (ValidForCapexRead == true)
{
return false;
}

return base.CanConvertFrom(context, sourceType);

}

public override bool CanConvertTo(ITypeDescriptorContext context,
System.Type destinationType)
{

return base.CanConvertTo(context, destinationType);
}
}

DateTime xmas = new DateTime(2007, 12, 25);
Console.WriteLine(xmas.Subtract(DateTime.Today).Days);

This is simple enough since all you need to do is basic date arithmetic and subtract today's date from 12/25/2007.
