Hi,J4amieC.. Below is my code which i have changed.. But somehow when i run the program, the database does not show out when i click on the date. Is there's anything wrong or i still missing on some part??
DateTime selectedDateTime = CAL1.SelectedDate;
SqlConnection conn=new SqlConnection("my connection string");
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "SELECT * FROM Particulars WHERE DateField = @Date";
cmd.Parameters.Add("@Date", SqlDbType.DateTime).Value = CAL1.SelectedDate;
Thanks for your help!!

I am now using Random r=new Random() to generate random number.
Now for debugging purpose, I want want my program to generate same random number every time i run it. I guess i need to use a fixed seed in order to do that. but i do not how. Can anyone please give me some suggestion?
Thanks

A quick search on MSDN:
public Random(int Seed);
Simply provide the same seed.
Cheers,
Vikram.

I like to use windows shell icons in my program as menuitem icons. How can i include those without extracting them first and then import as resource?
EG:
I have a file menu and would like to have a blank page icon next to the new file entry.

Use a program like the free IrfanView to extract icon images out of the shell icon library file (shell32.dll).

The question was, to do it without extracting them first.
Point is, that i have some example programs that do not have in included icons but show them in the menu. They aren't written in c# so maybe its something c# cant do, but i like to understand how it works.

Hi,
I am still new at C# and am coding an app that has tabs and on each tab is a treeview. I need to figure out which tab is selected and wich node on the treeview is selected for the current tab when the user clicks on certain menus.
I found a way to do it, but was wondering if there was an easier way.
TreeNode node;
string tabName = _tabs.SelectedTab.Text;
switch (tabName)
{
case "One" :
node = _tvwOne.SelectedNode;
break;
case "Two" :
node = _tvwTwo.SelectedNode;
break;
case "Three" :
node = _tvwThree.SelectedNode;
break;
}
Thanks in advance.

If you only have TreeViews on the tabs, you could use this code:
TreeView tv = ( TreeView ) tabControl1.SelectedTab.Controls[ 0 ];
TreeNode activeNode = tv.SelectedNode; Or, to get really terse:
TreeNode activeNode = ( ( TreeView ) tabControl1.SelectedTab.Controls[ 0 ] ).SelectedNode;

In reference to my previous post, you can use that code with TabPages that have more than just the TreeViews on them. You just need to ensure that the TreeView is the FIRST control added to the TabPage.

Search CodeProject or the web for "single instance application". There's some decent articles on CP regarding this, for example, here[^].

 Hi, I have a form that launches an external shockwave flash program and need to check, first, if the flash player is installed on the PC. Any ideas?
Thanks ahead!

You check for the existence and validity of the HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ShockwaveFlash.ShockwaveFlash key and its subkeys.

Hi
In a manual from a beamer i found following command data to switch the beamer to Power On.
02H 00H 00H 00H 00H 02H
What does this line means? Are this Bios Interupts?
I try to get this Data to the Beamer using System.Io.Ports.
But i don't know how. As a string? As a Byte?
System.IO.Ports.SerialPort sPort = new SerialPort("COM1", 38400, Parity.None, 8, StopBits.One);
sPort.Open();
sPort.Write( --> What? string? byte[]? char[]? <--)
sPort.Close();
Best Regards
