Hi To all ,
I didnt find help for this so i am posting inthis forum .
Now , i want to enter text when i click on grey area whether it is on any row or particular colum dynamically like entering text into textbox for datagridview .I dont know whether this feature supports to datagridview .
After running the form(design Mode for my application ),Actually i am creating an instance of datagridview and placing at any point. Then he clicks a Row Header Cell or ColumHeader cell Which are in GREY color and he writes Text (Empno ) at that instance like entering text into textbox .I dont want to give the user to enter text in cells only he can enter text for header (Both row and column ). This is all in design mode .
(In run Mode for my application )If we open that particular Form again , He cannot change the text of Column and row Headers but he can enter text in cells .This is the way i have to design the datagridview .
(For saving and retrieving) , i want to save all this data which is in Datagridview in an XML file and i have to retrieve the same .

I am using Adodb recordset to get the count of the total number of rows reterieved from a query?
In vb6 we can get this easily with
myrcd.recordcount
but if I use the above statement in vb.net 2003 it return -1.
Can we get count from reader without putting this in a loop to count every single record?
Thanks In advance

Why are you starting VB6 ? VB.NET is free, and VB6 is a dead, unsupported language.

I am still confused on what you are trying to accomplish. Are you wanting an index value to determine what report to print? By the way, every control has a Tag variable. You could set integer values in the tag to differentiate betten the menu items.
Cheers!
Richard
may your code be error free.
(okay, maybe two lines.)

Please post the code of how the menus are dynamically generated.
may your code be error free.

[code]
Dim mShowMenuItem As System.Windows.Forms.MenuItem
mShowMenuItem = DirectCast(sender, System.Windows.Forms.MenuItem)
mShowMenuItem.MenuItems.Clear()
Dim n, i As Integer
Dim a, b As String
s = "Select srno from cash"
com = New OleDbCommand(s, con)
con.Open()
dr = com.ExecuteReader
While dr.Read
n = dr(0)
End While
con.Close()
For i = 1 To n
s = "Select account from cash"
com = New OleDbCommand(s, con)
con.Open()
dr = com.ExecuteReader
While dr.Read()
a = dr(0)
Dim mSubSubMenuItem As System.Windows.Forms.MenuItem
mSubSubMenuItem = New System.Windows.Forms.MenuItem
mSubSubMenuItem.Index = i
mSubSubMenuItem.Text = a
mSubSubMenuItem.Enabled = True
mSubSubMenuItem.Visible = True
AddHandler mSubSubMenuItem.Click, AddressOf MenuClickHandler
mShowMenuItem.MenuItems.Add(mSubSubMenuItem)
i = i + 1
End While
con.Close()
Next
this will generate menus
Public Sub MenuClickHandler(ByVal Sender As Object, ByVal e As System.EventArgs)
'Don't know wt to write here
End Sub

I'm playing around with the above method and I'm trying to calculate and display the difference between two dates. I'm getting the error "Value of type 'system.timespan' cannot be converted to 'string'". Can someone provide some guidance. Thanks. The following is my code.
Dim dateadd, datesubtract As System.DateTime
Dim datedifference As System.TimeSpan
Dim Date1 As System.DateTime = System.DateTime.ParseExact("20051127", "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture)
Dim Date2 As System.DateTime = System.DateTime.ParseExact("20061127", "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture)
datedifference = Date2.Subtract(Date1)
MessageBox.Show(datedifference)

The last line is the problem, that's where you assume a timespan is a string. Try the ToString method on the timespan object.

Hi George,
compiler errors and run-time exceptions tend to show line numbers
(look at Exception.ToString(), not Exception.Message).
The Visual Studio editor can show them too, but for some mysterious reason does not do so
by default; see menu Tools/Options/Text Editor/All Languages/General/...
If you turn them on, you'll locate problem spots much more easily.

HI
for the lie you wrote
MessageBox.Show(datedifference)
"datedifference" is not string....
TO resolve your issue you can convert datedifference's "value" to string using something like ctype
may be the this will work for you
MessageBox(Ctype(datedifference,String))
Good Luck

Hi,
If you want to add a icon to a menu item simply put the MenuStrip component on the form, and click where it says "Type here", type something, and then go to the properties window and click the part that says "Image", or you could use this code: FileToolStripMenuItem.Image(ImageName or path goes here) you will have to change the names accordingly.
Hope it was useful.

First step - buy a beginners book. A paper one. One you pay for, instead of stealing it ( most 'e-books' are not free ). Work through that, first.

Ok, this one is driving me nuts, can someone tell me what I am doing wrong?
I have a few MDI child forms open within a parent.
I need to run a sub on one of the child forms when an event occurs on another.
For example one of the child forms is created in the Load event of the MDIParent with the following:
Dim ChildForm2 As New GraphFrm<br />
ChildForm2.MdiPrent = Me<br />
ChildForm2.Show()
The GraphFrm contains a Sub UpdageGraphs() but when I attempt to call ChildForm2.UpdateGraphs() from the parent or any of the other MDI child forms I get an error that ChildForm2 is not declaired.
How do I make this instance of the child form accessible to the Parent and other child forms?

Use delegates to call methods between forms.
