If you had, at the very least, searched the CP articles, you might have found MS Outlook style Calendar[^].

You didn't search, so you didn't find. Think yourself lucky that I'm in a good mood today, for a change! Smile | :)

Registry Editing

I am trying a program to add keys, however i am getting an exception saying
System.UnauthorizedAccessException : Cannot write to registry key
You can consider me beginner in registry editing issue.

using System;
using System.Security.Permissions ;
using Microsoft.Win32;

public class RegistryEditor
{
    public static void Main()
    {
        try
        {
            RegistryKey hkcu = Registry.CurrentUser;
            RegistryKey hkSoftware = hkcu.OpenSubKey("Software");
            RegistryKey hkMicrosoft = hkSoftware.OpenSubKey("Microsoft");
            RegistryKey hkIshaan = hkSoftware.CreateSubKey("Test1");
            hkIshaan.SetValue("Name", "Ishaan");
            hkIshaan.SetValue("Age", "20");
            hkIshaan.Close();
            hkSoftware.Close();
            hkcu.Close();
        }
        catch (Exception ex)
        {
            Console.Write(ex.ToString());

    }
}

Two things:

1) You can concatenate your two OpenSubKey calls:

RegistryKey hkMicrosoft = hkcu.OpenSubKey(@"Software\Microsoft");

2) The OpenSubkey has 4 overloads. If you look it up on MSDN the last one allows you to specify the RegistryKeyPermissionCheck (what you can do with subkeys), and RegistryRights (read only, read/write TakeOwnership etc.).

I am still on XP, so I don't know how this applies under Vista and Weven, which I know are a bit more picky about these sorts of things.

Hope that this is of some help! Smile | :)

Hi everyOne.
I have dataGridView in my project whitch is Bind to my dataBase
(Student's Table).After 3 months that the user has Saved around 3,000 rows in that table Now when they open that form with 3,000 Rows in Student's table it takes along time to load the form(Form become white).
What should i do to run that form without any problem and Quickly?
Thank u.

CanI

Re: DataGridView Binding.(Takes along time to load)

Henry Minute12-Sep-09 3:35

You need to filter what is retrieved and or displayed.

To filter what is retrieved, put a WHERE clause in the SELECT statement, to limit it to students whose name begins with 'A', for example. then allow the users to hit a 'Next' or 'Previous' button to move from the 'A's to the 'B's and vice versa. Or by their Major, or whatever.

To Filter what is displayed, the BindingSource has a Filter property that you can use to get a similar effect.

Hope this helps! Smile | :)

checkedlistbox in c#

hi guys,
i use in my form a checkedlistbox ...my problem is that when i write this code this.checkedListBox1.SelectionMode = SelectionMode.One; i would expect only one checkbox to be checked every time.But in my case i can select all the checkboxes so something is wrong..
thanks in advance..

Re: checkedlistbox in c#

Eddy Vluggen12-Sep-09 1:48

Eddy Vluggen

12-Sep-09 1:48

I guess that the CheckedListBox can only have one selected item (meaning that only one row has highlighted atta time)

That doesn't limit the number of check's that the user can set. Checkboxes aren't mutually exclusive, they "hint" that the user can check multiple items. If you want a mutual exclusive selection, try changing to a RadioButton[^].

The radiobutton allows the user to select 1 item from the list of options.

Henry Minute12-Sep-09 1:50

12-Sep-09 1:50

I haven't checked this out, since I don't have VS on this machine, but SelectionMode usually refers to the Items in the ListBox not the CheckBoxes.

I do not know of any simple way to restrict how many items are checked. You can periodically check on the CheckedItems collection and uncheck any except for the one you want, but what event you would use to trigger this checking, I do not know. Smile | :)

Alan N12-Sep-09 3:55

Hi,
Confusingly the SelectionMode does not refer the number of items that may be checked but the desired effect is possible through the ItemChecked event.

The new item is checked only after the handler returns and so single selection can be achieved by simply removing all existing checks.

private void CheckedListBox_ItemCheck(object sender, ItemCheckEventArgs e) {
  if (e.NewValue == CheckState.Checked) {
    CheckedListBox clb = sender as CheckedListBox;
    if (clb != null) {
      // remove all current checks
      foreach (Int32 index in clb.CheckedIndices) {
        clb.SetItemCheckState(index, CheckState.Unchecked);
      }
    }
  }
}

Alan.

Hi,

checkedlistbox.selectionMode can not limit the count of selected items

you can use JS code to control

or you can try: GroupBoxCheckBox or GroupBoxCheckBox

hi
i developed a project and a setup is made using dotnet.
my requirement is it should run only in one system.

suppose if a client has 10 systems
if i install it in system1, then it should run in system1 only

if the same setup is installed in system2 then it should not run

is it possible

Yes. Find something to identify the computer that the application is installed on (harddisk serial, computer name), and check whether this has changed during your last run.

Direction of increasing a LabelText ?

Hi.

Whenever I change the text of a label with long text the direction of the increasing is to the right.
like these images :
01[^] >> 02[^]

I want to change it, I mean I want to change the direction to the left !
Could you please guide me ?

Thanks.

Just a guess, but if in your case you have a langauge which is read from right to left than you can use the RightToLeft property of the label and set it to true.

OriginalGriff12-Sep-09 1:02

Because the label always assumes it's position from the top left corner (like all controls) it will not automatically grow to the left. The only way you can do what you want is to set the TextAlign to MiddleRight, TopRight or BottomRight, and set AutoSize to false. Manually set a good size for the label, and the text will grow to the left.
