Hello,
I hope you don't feel that I'm kind of rude with my statements.
I just wanted to point out that, specialy for a beginner who has a problem at his low level application, it's not a big help to point him to this.

I do agree, and you made me curious about that.

I had a short watch, and have to say that it's not much diverent then the article of Colin Angus Mackay, as he also explains the usage of delegates.

Thank you for that interensting link.
All the best,

hi,
how do I filter column for a DataGridView?
I've loaded the data like this:
DataGridView.DataSource = ExampleSource;
DataGridView.DataBind();
the Data is shown correctly in the Grid, but there are
to many of them. So i'd like ti filter them.
Where must be a way to make specific Columns invisible.
I've used foreach like this:
foreach (DataGridColumn column in DataGridView.Columns)
{
...
}
but he does go through the foreach-loop.
also i haven't managed how to delete the specific column
by searching it with a string.
i'll be grateful for any help
PS: Sry about my bad english...

Hello,
The ContextMenu property is a member of System.Windows.Forms.Control.
So if you set the property correct, you don't have to care about the position of the menu.
System.Windows.Forms.ContextMenu contextMenu1 = new System.Windows.Forms.ContextMenu();
System.Windows.Forms.MenuItem.MenuItemCollection mic = new System.Windows.Forms.Menu.MenuItemCollection(contextMenu1);
mic.Add("test1");
mic.Add("test2");
button1.ContextMenu = contextMenu1;
All the best,
Martin

Thank you

Why creating ?
Just use context menu. Take a new context menu, than set context menu in richTextBox to that new context menu.

hi!!
i had been refering to article 'passing values betn forms'.
I tried from it, but still i cant pass my variable from form1 to form2.
I m getting error on passing my variable to the other form's variable.
i have used the object approach from that article :
http://www.codeproject.com/useritems/pass_data_between_forms.asp
Objects of forms are created properly.
This i have written in form1 :
p = ((form1)log).n;
// log is object of form2.
//variable 'n' i have to bring from form2,which contains a date from query fired.
but i m getting error :
'Object reference not set to an instance of an object.'
It would be v.nice if u could help on it.
Thanx.

If u have time, till 2mrw eve. whenever u have time, just try it, i have done this:
This is in FORM1 :
public partial class detail_form : Form
{
public DateTime n;
....... ( ... this means other not related coding is done here.)
}
private void button1_Click(object sender, EventArgs e)
{
conn.Open();
string strQury = "";
strQury = "insert into dashboarddealerlogin (logoutdatetime) values '(" + DateTime.Now + ")'";
SqlCommand cm = new SqlCommand(strQury, conn);
n = Convert.ToDateTime(cm.ExecuteScalar());
conn.close();
}
In FORM2 :
public partial class login : Form
{
DateTime p;
.........
}
private void login1_Click(object sender, EventArgs e)
{
SqlCommand cmd = new SqlCommand();
conn.Open();
cmd.Connection = conn;
......
p = ((detail_form)log).n;
.........
}
I have to use this 'p' in FORM2 function :
public void funEntrylogin(int strlogid, int strdashid, string strname, string strpwd, DateTime logindate, DateTime logoutdate)
in place of 'logoutdate'.
This is my full code.
Plz chek n try it wen u have time,i'll wait.
Thanx Nekshan.

Why do you keep creating new threads about the same question all the time?
I have already explained exactly why your code is not working. I have also told you before that I already have explained why your code is not working.
Would you please read my reply before creating any more threads about this?

After 'login' a 'grid form' opens,it has a logout button, on logout that datetime value must go in a table.
Thanx.
Take care

Hi,
I was wondering how to access a method in a form from another form. I know that this implies using the 'static' modifier, however, this seems to be very troublesome.
I was thinking there should be a way to access the instance of a form at realtime to use one of it's public methods.. (The form of which the method I want to call happens to be the main form of the application) Does anyone know how to do this? I'm stuck
Actually I was considering using the Observer Pattern for solving this problem, however I expect there should be a much more straight-forward solution..?
With kind regards,
Johan Vandewalle

No, it doesn't.

The observer pattern is a good solution. You can get an example in this article about passing values between forms[^].

I hope someone can come up with a better method, but here is how I solve that problem.
In the second form, make a new function (or put it in the form's constructor) which accepts a form as its argument and stores it in a local variable (perhaps called mainform). From Main(), call this function and pass the main form.
Now, to call something withing the main form's class just use: mainform.mymethod();
