Are you embedding Windows Media Player in your program to play sound?
|
|
|
|
|
At the moment im using
Private Declare Auto Function mciSendString Lib "winmm.dll" (ByVal cmd As String, ByVal ret As StringBuilder, ByVal retLen As Integer, ByVal hwnd As IntPtr) As Integer
that way I have the option of using a player...or just a sound

There has to be an API for doing this in windows...sndvol32 does it in XP...Maybe I should look for the command line arguments for it, but then it would make the app XP dependant....hmm what to do what to do

All,
I've created a timer program that when it ends, displays a password form (no border) via showdialog that is maximized when displayed. The form contains one group box that holds my text box to enter the psw in and an enter button to confirm.
My problem is that I won't know what resolution a person screen may be set to and when the form loads on their PC, I want the group box to be centered in the middle of the form to ensure it will always be visible.
I know it sounds simple (probably is), but I can't seem to get the group box to center when I try different resolutions. My fear is that if I don't get it to center, it may very well show too far off to one side on someones computer and they will not be able to do anything but shutdown. Plus centered looks must more professional as well.
All help is greatly appreciated!
Thanks, everyone.

Private Sub Form1_ResizeBegin(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize<br />
Dim x As Integer = CInt((Me.Size.Width / 2) - (Me.GroupBox1.Width / 2))<br />
Dim y As Integer = CInt((Me.Size.Height / 2) - (Me.GroupBox1.Height / 2))<br />
<br />
Me.GroupBox1.Location = New Point(x, y)<br />
End Sub
The height seems to be offset, but this might get you closer to your answer.

That did it!!
Thank you very much.

The height will be offset because you have to accomodate for the titlebar(which is normally 30 pixels) and the bottom edge(which is normally 3-4 pixels).

Thanks. Do you know of a property for the client area only?

Ok, i've come up with this:
Dim y As Integer = Me.Bounds.Height / 2 - Me.GroupBox1.Height / 2<br />
Dim x As Integer = Me.Bounds.Width / 2 - Me.GroupBox1.Width / 2<br />
Me.GroupBox1.Location = New Point(x, y)
This will center your control, in this case, a groupbox within the forms client area. However ther may be one drawback (depending on how you see it). If you have a docked menu at the top of your form, the control will center itself between the bottom of the form and the menu. I'm guessing the same goes for any docked menu on any side. Other than that, i think this works quite well.

Hi,
I have to import data from .csv file (which contains 4 different columns like firstname,lastname,DOB,SSN) into Oracle database by using vb.net and asp.net(web application). This .csv file is very bulky file which may containts upto 10,000 rows.
Can any body tell me that what is the faster way to do it thru web page.
Any sample code or link is available which solve this issue than it would be very much helpful to me.

Hi, I have an old laptop which is running windows xp professional. I have a problem with my keyboard that the M and N key seem not to be funtion sometime. I need to press it very hard in type M or N character.
If I work in windows, it doesn't has any problem becuase I could use the utitlity call On screen keyboard to type this character. But when I start logon or my computer is lock and need to unlock and this key is the part of my password or username, it is really make me in trouble.
From here, I would like to write my own software or find any software that attach itself to winlogon.exe which consist of small button if i could not type my keyboard they i will use this button to load an on screen keybaord or other tool that i could click on the character that I could not type. I used to use windows xp tablet pc edition and i found that Microsoft have attach the keybaord button for user to use the pen to type it.
Does anyone has any idea?

The winlogon.exe is a Microsoft Windows program that has the key functionality of the logon interface. I do not believe it will be possible or wise to alter or enhance the program that may leave security holes in the OS (I have know idea whether what you are thinking will or will not, but it is still a possibility). Their are some programs that I know add some functionality to the winlogon.exe program to customize the interface or add alternative login forms (examples: fingerprint reader or LogonStudio from a Windows Skinning company), but I don't know how exactly they do it.
It may be easier to just change the password or username. Or for that matter get a new keyboard if the keyboard is really interfering with your productivity.

Thank you very much for your suggestion. I think I might use automatic logon when my keyboard came to normal. I can't purchase an external keyboard because sometime I need to make a presentation with this laptop on the road.
Thank again for your suggestion. Happy new year!!!

It's a heck of a lot easier to replace the keyboard or just buy ($10 US) a normal desktop keyboard and plug that into the laptops keyboard port.

I have a click event for multiple buttons
i.e but1, but2, but3, etc...
Private Sub Buttons_Click(ByVal sender As System.Object, ByVal e as System.EventArgs) Handles but1.click, but2.click, but3.click
End Sub
(you get the idea)
What I want to do is determine the exact button that was clicked.
I tried this...
dim con as new control
if con.gettype.name = "Button" then
output.text = con.text
end if
obvisously no luck.
Any pointers for a novice?

That will only create a new unused control, that has nothing to do with any of the controls in your form.
The sender argument contains a reference to the control that caused the event. Cast it to the type of your control.

Again I am a novice... so I am trying to understand the concept/terminology of what is going on here.
The sender is system.windows.forms.button
Under control it is System.Windows.Forms.Control.ControlCollection
Assuming I am following the information that you wrote correctly the control that would have caused the event would be Owner/Name: "but1"
There is not a type listed under the Control.ControlCollection.
I do not follow "Cast it to the type of your control"
|

If your button click event handler:
If TypeOf (sender) Is Button Then
Dim cb As Button = DirectCast(sender, Button)
' Do whatever you want with the button. cb is
' now the button that was clicked.
End If

The sender parameter is a reference to the instance of the control that caused the event, not just the type of the control.
If the sender is a Button, cast the reference to Button, and you have a reference to the button that was clicked:
Button senderButton = DirectCast(sender, Button)

if(((Button)sender).Text="Button")
{
output.text=((Button)sender).Text;
}
or
Button con=(Button)sender;
if(con.Text="Button")
{
output.text=con.Text;
}
You don't have the con variable defined so I am assuming the event handlers object paramter is sender. The code is in C#, but you should still get the general idea.

How do you make a button,
1)change the name displayed to the user when a user clicks it
2)make 10 images rotate in a picture box using timers.
Ex. button says 'move', user clicks, 10 images rotate to timer and button name changes to 'stop'. Users clicks 'stop', images stop rotating and button changes to 'move'?
I am using VS 2003

On your form, add your picturebox, your button, an imagelist and a timer. In the code i will be giving you, everything is named to default (e.g. button1, picturebox1, imagelist1, timer1), you will have to rename these if your's are named different.
Do this in declarations:
Dim ICount As Integer = 0 ' declare the counter for our images
Form Load:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
Me.PictureBox1.BackgroundImage = Me.ImageList1.Images.Item(0) ' Set the picture box to display the first image in the series<br />
Me.PictureBox1.BackgroundImageLayout = ImageLayout.Stretch ' Make the image stretched ''This is optional<br />
End Sub
Button Click:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
If Me.Button1.Text = "move" Then ' if the timer isn't running and the text = "move" then<br />
Me.Button1.Text = "stop" ' change the text<br />
Me.Timer1.Enabled = True ' and start the timer<br />
Else ' if it is running and the text = "stop" then<br />
Me.Button1.Text = "move" ' change the text<br />
Me.Timer1.Enabled = False ' and stop the timer<br />
End If<br />
End Sub
Timer Tick:
<br />
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick<br />
'index for images starts at zero, so on the tenth image the index will be 9, so we have to minus one to accomodate<br />
If ICount = Me.ImageList1.Images.Count - 1 Then 'Check if it's at the last image, and start again if so<br />
Me.PictureBox1.BackgroundImage = Me.ImageList1.Images.Item(0) ' change to first image<br />
ICount = 1 'set the count for the next image<br />
Else<br />
Me.PictureBox1.BackgroundImage = Me.ImageList1.Images.Item(ICount) ' if it's not the last image, go to next image<br />
ICount += 1 'set the count for the next image<br />
End If<br />
' the icount is an integer that is increased after each change, then each subsequent change will be the next image in series<br />
End Sub<br />
