Hello,
You may take a snapshot of Form using PrintToBitmap function of Form.
Following is a code snippet to do so-
bmp = New Bitmap(Me.ClientRectangle.Width, Me.ClientRectangle.Height)
Me.DrawToBitmap(bmp, New Rectangle(Me.ClientRectangle.X, Me.ClientRectangle.Y, Me.ClientRectangle.Width, Me.ClientRectangle.Height))
Me.PictureBox2.Image = bmp
If you want to print this data then you will need to add one PrintDocument object, like this-
Dim WithEvents pdoc As New System.Drawing.Printing.PrintDocument
Add code in PrintPage Event of PrintDocument object something like –
e.Graphics.DrawImage(bmp, Me.ClientRectangle.X, Me.ClientRectangle.Y)
Then you may get it printed by simply using a line of code-
pdoc.Print()
This would print the picture of the form.
I hope this helps .

Use the Color.FromName method.

You can only convert from a string to types that have a natural representation as strings, like a number.
You should really learn how to read the documentation yourself, instead of having to ask others to do it for you. It's all there, and it's much faster than waiting for a reply in a forum.
To create a Font object from the name, use one of the constructors of the Font class. You have to at least supply the font size also.

Lets see the code that you are using to save to the DB not DAtaset. and what DBMS you are using. Access or SQL?

Hi,
thnx for ut reply.I am using Ms-Access 2003.
I am showing u the code,
this is the code i am using to update the data,
Dim res As Integer = executeDML("update schedule set [date]='" & txtdate.Text & "',[vehno]='" & ComboBox1.SelectedValue & "',[from]='" & txtfrom.Text & "',[from_time]='" & txtfromtime.Text & "',[to]='" & txtto.Text & "',[to_time]='" & txttotime.Text & "',[driver]='" & txtdriver.Text & "',[remarks]='" + txtremarks.Text & "' where [id]=" & scheduleid)
If res > 0 Then

MsgBox("Error while Updating Record!!")
End If
executedml is function defined in module which is,
Public Function executeDML(ByVal command As String) As Integer
Try
com.CommandText = command
com.Connection = con
makeConnection()
rs = com.ExecuteNonQuery()
closeConnection()
Return rs
Catch ex As Exception
If schedulecode = True Then

End If
End Try
End Function
i have degug the code also everything runs properly.
So,wt could be the problem?

The Access database is part of your project. The file is also tagged as Copy Always when you build and execute your project. So, every time you hit F5 in the debugger, it copies the database from your project folder to the Debug folder your .EXE shows up in, overwriting the database your code is actually using.

Here[^] is a useful link.
An interface allows you to define a set of methods that can be implimented by classes even if they have no common root.

Basically I want to Authenticate a User name and Password that is saved in a text file. The username and password is saved in a text file from a Persons Form. I want to call each object (username & password) to authenticate itself with a login form.

I am writing some controls, and I would like to have Compound Properties similar to the built in "Font" Property where I can have a single property with several sub Properties.
Say I want a Property BackColors() with sub properties of Normal(), Hover(), Pressed(), Disabled(), and Alpha() inside it, and be able to browse it in the property window with the +/- button rather than opening a collection window.
I hope I am making sense. I woudl put a picture on, but this board doesn't seem to let me, as far as I can see.
I have looked everywhere in my current books, and online for a way to make complex properties like this but I only find basic stuff for single properties.

Hey guys, I was just wondering if it is possible to have a program that searches the screen for a certain color in VB.Net via input of RGB values or the built in color tool. Also if that is possible is it possible for it to click or rick click on the spot where it found the color? Any help is appreciated.

Hello,
I have created an application that creates Active Directory users. The application is working fine. I read and write some settings to the application settings with My.Settings.mysettingname
Here comes my problem, I would like to have multiple templates into my application so that if a dropdown box value has "template1" selected other values like department, location, etc. are changed depending on the selected template.
What is the best method to read and save data to? Could i use an Access database? Or is it better to use a XML file or INI file? And how could I read and write to the advised method?
Any help is appriciated. Thanks in advance.
Kind regards,
Roland
