You should have explained your question more exactly or at least write the code, but just a hint for you:
you should try refreshing your form after drawing anything on that...

Hey everyone,

I'm attempting to write a VB .NET program for my pocket pc (e800) which does the following:

I have a form. The form has a button. I press the button and the program captures an image taken from my HP Photosmart Mobile Camera.

The question is, will browsing through my pocket pc's Windows directory I noticed a number of application extensions related to my HP camera. How can I access the functionality of these extensions to incorporate camera functionality in my own apps?

Thanks!

Sean

Your question would be better handled in the Embedded/Mobile Forum[^]. You question is more specific to the platform functionality than it is to VB.NET.

Trying to get the enter key to not make noise

Hello,

The code works but the when you use the Enter key the program Beeps at me and I would like to stop that but still move to the next control.

Private Sub controls_KeyDown(ByVal Sender as object, BayVal e as Systes.Windows.Forms.KeyEventArgs) Handles combobox.KeyDown, textbox.KeyDown<br />
 If e.keyCode = Keys.Enter Then<br />
  Me.SelectNextControl(Ctpe(Sender, Control), True, True, True, False)<br />
 End If<br />
End Sub

I have also tried many variations of code that is in the if block like SendKeys.Send("{TAB}") still makes the Beep

Thank you

The Enter and Tab keys are making noise because they are not valid keypresses at the time. Do you have all of your controls TabStop properties set to False? There is a condition setup somewhere that is making the default keyboard handlers (not your handlers!) in the form think that the keypress is not valid and, therefore, generates a beep to signal such an error.

The Tab key work just fine and does not Beep the Enter key Beeps only when it exits the if statement. All the TabStop properties on the ComboBoxes and TextBoxes set to True. The GroupBoxes the house the Combo and TextBoxes to do not have a TabStop properties (I think they are false all the time). The only other event that I have code in is SelectionChangeCommitted for the ComboBoxes and that I use to change a bunch of other things when it happens.

I don't think I have any setup condition that touches the default keyboard handlers.

Also the wired thing is that the Tab key does not fire the keyDown Event.

Thank you for you help

Try using the following code instead, it should work!
(I haven't checked if it works or not.)

<code>Private Sub controls_KeyDown(ByVal Sender as object, _
BayVal e as Systes.Windows.Forms.KeyEventArgs) Handles combobox.KeyDown, textbox.KeyDown
If e.keyCode = Keys.Enter Then
e.Handled = True
Me.SelectNextControl(Ctpe(Sender, Control), True, True, True, False)
End If
End Sub
</code>

Your forget the ' character at the beginning and ending of your search string. Your code should be:

StrSql = "select * from address where co_name LIKE '" & txtquery.text & "'" but it just query the data from your table only.

HI All,

I have a simple program where I insert values into a Sql Database.
The following is my INSERT code:

Public SqlConn As New SqlConnection()<br />
    Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click<br />
<br />
        SqlConn = New SqlConnection("Data Source=SOORAJ;Initial Catalog=TrackEmp;User Id=sa; Password=; ")<br />
        Dim cmdText As String = "INSERT into EmpMaster(Name, Age, Gender, Address, TelephoneNo, MaritalStatus, Salary, Post,Department) Values ('" & txtName.Text & "','" & txtAge.Text & "','" & gSex & "', '" & txtAddress.Text & "', '" & txtPhone.Text & "','" & mStatus & "', '" & txtSalary.Text & "','" & txtDesignation.Text & "', '" & txtDept.Text & "')"<br />
        SqlConn.Open()<br />
        Dim cm As New SqlCommand(cmdText, SqlConn)<br />
        cm.ExecuteNonQuery()<br />
        SqlConn.Close()<br />
        MsgBox(" The Employee has been Added")<br />
        txtName.Text = ""<br />
        txtAge.Text = ""<br />
        txtAddress.Text = ""<br />
        txtPhone.Text = ""<br />
        txtSalary.Text = ""<br />
        txtDesignation.Text = ""<br />
        txtDept.Text = ""<br />
    End Sub,

I have 3 tables in my Database.

Can someone tell me how to go about with the UPDATE And DELETE.

Thanks and Regards,

Hi,

It is not the statement I want but that my following code is giving me error.:

<br />
<br />
 Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click<br />
        SqlConn = New SqlConnection("Data Source=SOORAJ;Initial Catalog=TrackEmp;User Id=sa;Password=; ")<br />
        Dim cmdText As String = "DELETE FROM EmpMaster where [Name] ='" & txtName.Text & "'"<br />
        SqlConn.Open()<br />
        Dim cm As New SqlCommand(cmdText, SqlConn)<br />
        cm.ExecuteNonQuery()<br />
        SqlConn.Close()<br />
        MsgBox(" The Record has been Deleted")<br />
    End Sub<br />

This is the error it is giving me

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll

Additional information: System error.

Can someone tell me where I am going wrong??

Make sure your icons are set to be embedded resources by going to the properties of each icon you wish to include. Then, you can access the icon by the namespace of the DLL using the constructor for the icon class.

Dim myIcon as Icon
myIcon = New Icon(GetType(Company.MyProgram),"MyIcon.ico")

The full namespace for the icon is: Company.MyProgram.MyIcon.ico

Build actions for embedded resources are documented in the MSDN Library http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbconfileproperties.asp[^].

Remote execution is a HUGE security risk!

In order for Word to run, it requires a user account to be logged in. Why not just put Word in the Startup folder of All Users?

Not supported by normal means. You'll have to owner-draw the ListView yourself. The article search is taking awy too long to come back with results right now, but search the articles for "custom Listview" and you'll find a bunch of example on how to owner-draw a listview control.
