It depends on whether or not you are comparing strings or the date/time values. With strings you can obtain the item's text (Item[n].Subitems[0].Text) at that desired index (n) in each of the the listviews. Then compare the strings.

if( String.Compare(str1, str2) == 0)
{
  // do something useful...,
}

OR...,

if (CultureInfo.CurrentCulture.CompareInfo.Compare(str1, str2,
       CompareOptions.IgnoreCase) == 0)
   {
      // do something useful...,
   }

If you are checking the date/time. You need to convert the string to DateTime format then check it using:

DateTime t1 = DateTime.Parse("2007-09-09 21:44:21",
                       CultureInfo.InvariantCulture.DateTimeFormat);
DateTime t2 = DateTime.Parse("2007-09-09 19:24:20",
                       CultureInfo.InvariantCulture.DateTimeFormat);

if (DateTime.Compare(t1, t2) > 0)
    Console.WriteLine("t1 > t2");
if (DateTime.Compare(t1, t2) == 0)
    Console.WriteLine("t1 == t2");
if (DateTime.Compare(t1, t2) < 0)
    Console.WriteLine("t1 < t2");

Of course the time date string does not have to be a literal.

str1 and str2 are strings from subitems??

It gonna work like this:

when items adds in listview1 it gonna compare subitems[0] and [1] with subitems[0] and [1] in listview2. if they match, pass info listview2.subitems[4] to right item in listview1 and calculate the time... and remove that item in listview2!

How would you do??;P Sniff | :^)

(some code strip) Roll eyes | :rolleyes:

even hard to excplain!
Appriciate this man!!!

I understand what you are trying to accomplish. You should read up on the properties of the ListView control. When you fully understand the properties you will have no problems accessing and manipulating ListView strings.

The Items collection contains all the indexed items (0,1,2, etc), each Item can have SubItems (0,1,2, etc). For example, suppose I want to get a filepath from the ListViewItem that I have found. The path is the second subitem and the filename is the first subitem.

ListViewItem lvi = fileListView.Items[9];  // tenth item
string filename = lvi.SubItems[1].Text + @"\" + lvi.Text;

Now that I have the string I can do something with it (Compare!?). Be careful when iterating through lists and indexing items. If the you try to access an index that is more or less than the "Count" property of the ListView. It throws an System.ArgumentOutOfRangeException error.

Look at the examples there too.

ok... i check it out..
string[] lines = System.IO.File.ReadAllLines("dataapplikationer.txt");
Int32 index = 0;
while (lines.Length >= index + 10)
{
if ("#" != lines[index].Trim())
{
index++;
continue;
}
String appl = lines[index + 1];
String path = lines[index + 2];
String dest = lines[index + 3];
String pris = lines[index + 4];
String sort = lines[index + 5];
index += 10;
System.IO.DirectoryInfo subDI = new System.IO.DirectoryInfo(path);
foreach (String sub in Directory.GetDirectories(path))
{
foreach (String file in Directory.GetFiles(sub, "*.ini"))
{
String row5 = File.ReadAllLines(file)[4];
String section = row5.Substring(9, 6);
String subName = sub.Substring(sub.LastIndexOf(@"\") + 1);
DateTime time = DateTime.Now;
ListViewItem item = new ListViewItem(new string[] { sort, subName.ToString(), time.ToString(), "Summa tid", section, "AD", pris, appl });
this.listView2.Items.Add(item);
this.listView2.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
}
}
}

but how do i build it together in this code i want the sort, subName.Tostring() to compare in all items in listview1 and if it founds one equal then calculate time "summa tid" and pass by "av"??

Please man! help me build it together... peace!

Hi there .

I have a problem with SqlServer 2005 Log file .
I have an application and i want to attach my database to SqlServer , I did it by SqlConnection and ConnectionString ,in many times it gives me an error.

I know that when we use AttachDbFilename property in Connection for attach DB we don't need database log file, But most of times it gives me this error:

"Unable to open physical file 'filpath_log.LDF'. Operation system error 5: "5(error not found)".<br />
Could not open new database 'DbName'. CREATE DATABASE is aborted.<br />
Cannot attach the file 'FilPath.mdf' as database 'DbName'.<br />
File activation failure. The physical file name 'filpath_log.LDF' may be incorrect.<br />
The log cannot be rebuilt when the primary file is read-only.'

I wonder to say sometimes attachment works but sometimes not.
I already did this attachment process with SQLServer 2000 and it never gives me error .

How to display # using / and %

I am new to programming and just started learning C#. I am using Visual C# 2005. I am working on a project where the user enters 5 digit # and then I need the digits to display separated by a space. This is a console application.

I got as far as asking to enter # then displaying the digits by using / and %. I am having a problem showing the 2nd, 3rd and 4th #.

How do you get the just the 1st digit to the right of the decimal to show. I used for example:

digit1 = ( value1 / 10000);
digit2 = ( value1 % 10000);
digit3 = ( value1 % 1000);
digit4 = ( value1 % 100);
digit5 = ( value1 % 10);

I am having a problem with the 2nd, 3rd and 4th to display only the first digit to the right of the decimal. All have been declared int..any help is appreciated, thanks

Thanks. Hope my post is okay with detail if not let me know, this is my first post

Hi - welcome to Code Project.

digit2 = value1 % 10000

will give you the remainder when dividing by 10000. In essence, this means it will give you the last four digits. To get just the one digit, you'd also have to strip to the right, so something like this should work

Math.Floor((value1 % 10000)/1000)

The mod (%) strips values to the left, then the divide strips to the right. Finally, Math.Floor stops a result such as 3.6 from rounding up.

The other approach is to do this:

string number = value1.ToString();

digit1 = int.Parse(number[0]);
digit2 = int.Parse(number[1]);

etc

You don't need to use int.TryParse or char.IsDigit, as you know the values are all numbers. You DO have to make sure your number is 5 digits long, I'd be inclined to store the values in a list or an array, then you can write code that works with any length number.

Another possibility is comething like this. Obviously this will destroy the input value, but if its needed it can be saved first.

// value is the 5-digit input value<br />
int[] digit = new int[5]();<br />
<br />
for( int i = 4; i >= 0; --i )<br />
{<br />
  digit[i] = value % 10;<br />
  value /= 10;<br />
}

All the Best

You can drag it from the toolbox and drop it on the form to have it created automatically or you can create it like this:

TextBox mybox=new TextBox();

Key Presses

ahojed8-Sep-07 21:00

8-Sep-07 21:00

Essentially, I want to press a key while running my application and have something happen.

Let's say I have Form with 3 TextBoxes named tb1, tb2, and tb3. What's the best way of setting things up so that when I press '1' tb1 is focused, '2' tb2 is focused, and '3' tb3 is focused. I know I can set up KeyPress events for tb1 AND tb2 AND tb3 to do this, but that seems very redundant. Is there a way where, no matter who currently has focus, I can press '1' and give tb1 focus? Thanks for the help, sorry, I'm new to C#.

You can set up an event handler for the forms KeyPress event. You should set Form.KeyPreview property to true in order for the form to get all the events first
