OK, you have everything you need to figure it out. Every node is parent node to another collection. So, every child node you add has a Nodes collection, just like the root of the tree. It's up to you how you're going to keep track of which tree node is selected. All you have to do is track which node is selected and add anther node to it's Nodes collection.

Hello,
I'm hoping that someone can help me. I have a DateTimePicker, and I would like it to default to one month prior to the date that the form is opened... I have attached my code, if anyone could help me out I would thank you.
Aaron
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim month As Integer = DateTime.Today.Month
Dim endMonth As Integer = month - 1
TakenDate.SelectedIndex = TakenDate.Items.Count - 2
End Sub
|
|
|
|
|
Can you not use the "Value" of the control?
dateTimePicker1.Value = DateTime.Now.AddMonths(-1)

Noone is going to do your homework for you. If you have difficulties knowing where to begin, I would suggest speaking to your teacher/lecturer/tutor to find out further information.
Give it a go, then if you get stuck with a specific problem in your code, post the code and ask for assistance.

Hi everyone,
I copy/paste one datagridview from one form to another (different solutions) using two instances of VS 2005.
The target form has the datagridview with all settings, including the DataSet and tableAdapter used by the original form. The datagridview also has all old settings. Everything is fine, it works as expected, with one drawback: every time I make any change in the target form surface, VS tells me that the dataset and the tableadapter are not defined and no longer loads the form in design mode giving errors mention that the dataset and the tableadapter are not defined.
To be able to view the form surface in Design Mode, I have to edit the form.Designer.vb file and replace the references to the dataset and tableadapter as follows to Global:
replace Me.DataSetSyncLog = New MainTabForm.DataSetSyncLog
to Me.DataSetSyncLog = New Global.MainTabForm.DataSetSyncLog
and
replace Me.TAdapter_Log = New MainTabForm.DataSetSyncLogTableAdapters.TAdapter_Log
to Me.TAdapter_Log = New Global.MainTabForm.DataSetSyncLogTableAdapters.TAdapter_Log
Anywhere in the code if I do Me.TAdapter_Log = New MaintabFor.
the Intellisence does not show the table adapter. But it is in the form.
Any ideas on how can I fix it?
Thanks,
Paulo

I've never tried this, but it sounds like a quirk. Unless the dataset itself (like the .XSD, etc) was copied, how would project 2 know the def. of the dataset, tables, tas, etc?
Probably have to copy over the dataset, which I would argue against. Copying and pasting duplicated code is a bad idea.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Hi Jon,
Thanks for your answer.
Actually the dataset and data source I created in project 2 with the same names as in the project 1 before I copied the datagridview to project 2.
Internally in the project 1 the datagrid was bound to the datasource and it was pasted with all properties set correctly, the columns collection with all settings and etc.
The tableadapter was inserted into the surface of project 2 by VS after I pasted the datagridview, with the same name.
It is strange, ist'n?
Thanks,
Paulo

I guess if I was going to be really lazy. I'd create a new solution and copy all the source files from project 1 to project 2 (that way nothing is being reduplicated manually or being copied from open instances of VS); personally, this sounds whack. Add in all the existing source files. Change Form1 to whatever you want it to look like. Quick and dirty copied app w/ same functionality your looking for.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Hi all...
I am creating a simple database application program. I used VB.Net (VS2005) as frontend and SQL Server 2005 as backend. Now each time I run insert,delete or update query, it runs fine and shows changed made in application but it does not make permanently changes in database.
Suggest me what should I do to make permanent changes in database.
Thanks.

How are you doing this? Post some code.
Are you updating the database? Unless you do this, you will see the changes in dataset but not in DB.

code is :
imports system.data.sqlclient
try
dim str as string="update tblLogin set Uname='" & txtName.text & "',Passwd='" & txtPasswd.text & "'"
dim cmd as new sqlCommand(str,con) 'Con is declared as public sqlConnection
connectToDatabase.Connect() 'It is a method used to open connection if it is closed.
cmd.ExecuteNonQuery()
msgbox("Sucess")
catch ex as exception
msgbox("Error is : " & ex.message)
end try
'end code
Now the above code shows message "Sucess",it means query run sucessfully but it does not change actual data in database.
Suggest me what should I do now.
Thanks for quick reply.
