{
void abc()

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

When you invoke class1, it's constructor will be called automatically.

you cannot call constructor, it automatically called when you make new instance of the class

The line in bold is calling the constructor with no parameters. You could pass a string to call the contructor you listed.

add your class in an ArrayList, then bind that AL to your ListBox, something like this :

ArrayList AL = new ArrayList();
AL.Add(new ubi());
LB.DataSource = AL;
LB.DisplayMember = "UserName"
LB.ValueMember = <your control>

hope this will help

Hidding a tab page

Hi all,

I have read the documentation on MSDN regarding the tabpage control. It states that the tab page within the tabcontrol can not be hidden. According to the MSDN to hide it, one needs to remove it. This is quite hideous!

Isn't there another way of doing it?

Many thanks in advance

hi,

yes i have also faced this problem.
we can not hide tab page in tab control.
but i have find a solution by making one custom tab control which has "HideTabPage" property which allow me to hide tab page.

but you can also disable all controls on that tabpage, if you don't want to allow users to use controls on that tab page.

you ca use this code...

For Each ctl As TabPage In myTabControl.TabPages
If ctl.Name.Equals(tPageToRemove.Name) Then
For Each ctlchild As Control In ctl.Controls
ctlchild.Enabled = False
Next
End If
Next

by this code you can disable all controls on given tab page.

Thanks for the reply. Regarding your comment:

Could you perhaps give an example of this? Cause disabling all of the components on the tabpage is not what I'm trying to do.

Many thanks in advance

hi,
ok, i think building custom tab control will solve your problem.

i can give you logic for custom control.
logic of "HideTabPage" method is,
take array of tabpages control which are in custome tabcontrol.
and remove that tabpage from tabcontrol which you want to hide.
and when you want to show/display that removed tabpage then add taht tab page from tabpages array into tabpage control.

you can also modify this logic according to your requirement.

you can make some browseable properties also, so you can hide/show tabpages by setting property values.

I don't think so. Tab control is built for showing multiple tabs. Why you need to hide one tab page ? Are you looking for wizard kind of stuff ? Alternatively you can disable the controls in one tab page by casting the tab page into control and setting Enabled=false.

sorting

11-Mar-08 19:30

I wanted the sotring of string column(sql server 2000 database table).
the table contains the following entries

aa
02
18
1
11
22
1a
2

after sorting these entries by the same column.
it gives the following result

02
1
11
18
1a
2
22
aa

but the above sorted order is not required.

then look at the ascii chart
http://www.asciitable.com/[^]

Now according to my understanding , i thought i should sort the list in the order in which the ascii codes are listed.

Am I doing in the right direction ?

JustChiragPatel11-Mar-08 20:01

Hi,

yes, if we use ready made sorting function in .NET library then it will sort based on ASCII characters, but here i think your sorting includes numbers and characters and zero based numbers also, so i think you should make your own sorting function which will use Comparer class to compare values and then will sort based on your requirement.

this can only possible by third party tools, or just give .netframework with your application
