Try to use format
ex: Format(datetimepicker1.value.date, "dd/MM/yyyy")
HTH
|
|
|
|
|
string strDate = dateTimePicker1.Value.Date.ToShortDateString()
DateTime dt = DateTime.Parse(strDate)
It's working well. You can attemp to run it.
It seem to be a solution or an answer.
|
|
|
|
|
string myDate = dateTimePicker1.Value.ToShortDateString();
If you wish to convert it back to DateTime you can do it with :
DateTime.Parse(myDate);

Hi,
First,thanks for the replies.
I cant split the value to "mm/dd/yyyy" with using datetimepicker.value.date.toshortdatestring or datetimepicker.value.toshortdatestring. But when i use datetime.parse(string), the format will become "dmm/dd/yyyy HH:mm:ss" again. And if i use "Format(datetime,"mm/dd/yyyy")", its prompt me an error msg.
I would like to have the value in format "mm/dd/yyyy" is becouse i will insert this value into database.Please anyone guide me to the right way.
thanks in advance

hi fellows
i'm creating a class diagram in VS 2005, the class diagram option shows me all the classes of the project but it doesn't show the links between classes.
Is this because half my classes are "Serializable"

No - it's because it can't detect links between your classes, e.g. because you haven't inherited one from another.
Deja View - the feeling that you've seen this post before.

most of my classes are serializable i.e. thay cannot be inherited.
can u explain a little about Links between classes?
|
|
|
|

Errm - you can inherit serializable classes. Who told you that you couldn't?
Take the following example:
[Serializable]
public class A
{
private int count = 0;
public virtual void OnInit()
{
count = 10;
}
}
[Serializable]
public class B : A
{
public override void OnInit()
{
base.OnInit();
}
}As you can see, B inherits from A. This is perfectly acceptable (and both classes would serialize just fine.

VS 2003 that i'm working with tells me that serializable classes can't be inherited. i haven't tried inheriting them myself.
i'll just try it for myself.
Thanks for the example.

Hi,
i really don't understand your question.
You need to refresh the Grid (which is placed on Form1) from Form2?
If so: store a reference to your Grid from Form1 to your class Form2

I have a stupid question like this
How do I copy a row and paste it into a new row at run time?
I know I can use the getClipboardContent method and work with this content. It seems to be a bad way, even unexpected result.
Help me solve my problem .
Thanks in advance
It seem to be a solution or an answer.

My code is here
private void copyToolStripMenuItem_Click(object sender, EventArgs e)
{
DataObject obj = dataGridView1.GetClipboardContent();
str = obj.GetText(TextDataFormat.CommaSeparatedValue).Substring(1).Split(',');
}
private void pasteToolStripMenuItem_Click(object sender, EventArgs e)
{
try
{
DataGridViewRow dgvRow = dataGridView1.Rows[0];
for (int i = 0; i < str.GetLength(0); i++)
dgvRow.Cells[i].Value = str[i];
dataGridView1.Rows.Add(dgvRow);
}
catch (Exception ex)
{
}
}
But it throws an exception "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound"
I am very confused. Kindly help me. Thanks

Hi,
Would this be a good way to prevent some SQL Injections?
I am trying to find the best easiest way to use of command parameters whenever i receive user input to query a database.
I have alot of queries so im trying to find a easy reusable procedures to make use of sqlcommand parameters.
<br />
SqlConnection conn = new SqlConnection(_WebConfig.ConnectionString.ToString());<br />
try<br />
{<br />
<br />
DataTable dtVal = new DataTable();<br />
SqlDataAdapter da = new SqlDataAdapter("SELECT ID, Full_Name, Surname " +<br />
"FROM Users " +<br />
"WHERE Full_Name = @LoginUname " +<br />
"AND Password = @LoginPword", conn);<br />
da.SelectCommand.Parameters.Add("@LoginUname", SqlDbType.VarChar, 30);<br />
da.SelectCommand.Parameters["@LoginUname"].Value = LoginUname;<br />
<br />
da.SelectCommand.Parameters.Add("@LoginPword", SqlDbType.VarChar, 15);<br />
da.SelectCommand.Parameters["@LoginPword"].Value = LoginPword;<br />
<br />
if (conn.State == ConnectionState.Closed | conn.State == ConnectionState.Closed)<br />
{<br />
conn.Open();<br />
}<br />
da.Fill(dtVal);<br />
<br />
if (dtVal.Rows.Count == 1)<br />
{<br />
return true;<br />
}<br />
else<br />
{<br />
return false;<br />
}<br />
}<br />
catch (Exception ex)<br />
{<br />
throw ex;<br />
}<br />
finally<br />
{<br />
conn.Close();<br />
conn.Dispose();<br />
} <br />
Any advice or other methods would be greatly appreciated
Thanks

Hello,
Can you please tell me how can I MessageBox.Show the tag property of a listView item when a sub item is clicked?
Thanks.
|
|
|
|
|
ListView.HitTest returns an object that contains a reference to the ListViewItem AND the ListViewSubItem that was clicked.
If it was the first column, those will be the same; for subsequent columns, it will contain the correct item. You'll have to do some checking on those objects as it sets them to null sometimes and I forget now what the exact conditions are.

Hello everyone,
I am trying to create my own ContextMenu for a button in my Windows Application. The following is the code that I am using to have the ContextMenu. I was wondering how I can assign click event to the options in the ContextMenu?
MenuItem[] menuItems = new MenuItem[]<br />
{<br />
new MenuItem("Button Info. 1"),<br />
new MenuItem("Button Info. 2"),<br />
new MenuItem("Button Info. 3"),<br />
new MenuItem("Exit")<br />
};<br />
ContextMenu buttonMenu = new ContextMenu(menuItems);<br />
buttonMenu.Show(btnTest, new System.Drawing.Point(70, 30));
Thank you very much and have a great day.

Hi,
ContextMenu behaves like other menus; you can add MenuItems to it as you wish.
So I suggest you create one MenuItem, set all its properties, add it to the
ContextMenu; then continue with the next one.
