Re: How can I call properties a run time created button?

hi,

it is easier as you think

either you iterate the "Controls" collection of the Form:

For Each ctl as Control In Me.Controls
If ctl.Name = "GButton2" Then
ctl.Backcolor ....
Exit For
End If
Next

or you just call the following:

Me.Controls("GButton2").Basckcolor ...

storing it in an array is not necessary, because the added controls are already stored in an collection (Me.Controls)

Yes, of course it's not necessary, but it's the easiest and fastest way to get the reference.

Printing a form's text fields

Can anyone help me or point me in the right direction.

I am running VB.Net 2003 and have a form that I wish to print. For argument's sake, the form has 4 fields e.g. txtField1.text, txtField2.text, txtField3.text and txtField4.text

Each field has a value in it. How can I print this form or fields direct to my printer. The reason I want to do it this way is that each field has a complex calcualation to get to its value. Another way is how could I make a text file with these values and put onto a crystal report.

I hope this make sense.

How can I detect which button is clicked on the form?

Hello!

In shown sample below, I have a loop what ceates instances of a button. What I want to know is which one gets clicked in runtime? Thank you.

<code>
Public Sub AddButtons()

For I = 1 to 10
    Dim myButton as new Button
        myButton.text = "Hello"
        me.Controls.Add(myButton)

        AddHandler myButton.click, AddressOf myButtonEvent
Next

End Sub

' Here is the event handler for the button
Private sub myButtonEvent (Byval Sender as Object, e as EventArg)
    
     'Here I want to know which button has been clicked because there are 10 
     'buttons on the form.

End Sub
</code>

in your button event:

dim b as Button<br />
b= Ctype(sender,Button)

the b will be the button that was clicked.
If you are wanting to run different code depending on what button was clicked you can check for the name, or assign a value to the tag property and use that for identification.

Hope that helps Smile | :)

You would want to set the button id value.
Something like myButton.Id = "btn"+I.ToString();

Then in the event
CType(Sender, Button).Id to figure out which button.

Hope that helps.

Overrided install sub problem

Memo Soso13-Mar-07 4:56

13-Mar-07 4:56

With VisualStudio.Net, i'm using an installer class with a custom action
on my setup project to ask the user a serial number. A "Textboxes"
dialog on the "user interface" provides the serial number string to an
overrided version of then install procedure, inside my installer class.

My problem is that the install sub is able to verify the serial number
entered, but then i can't stop/cancel the installation procedure.

Why are you putting a label OVER the picturebox? Are you sure that the picturebox is actually linked to an image and showing it?

With .Net I have not found a way to use transparency with labels and show the background like you can do with VB6. I have had to resort to keeping the label hidden and using it's text,location, etc. in the picture box's OnPaint event using a graphics object to draw the text on the picture box.

Hope that helps Smile | :)

I was able to add a label to a picturebox and it's transparency worked fine. How are you creating the label. Is it done at runtime or design time. Remember that the location of a control is relative to it's parent. So if the label exists at design time and is located 100 from the left and 200 from the top it will be in that same relative position when you set it's parent to the picturebox. What may be happening is when you set the parent to the picturbox the label is positioned where you can't see it. Try setting it's position to (0,0) and see if it shows up. As proof of concept try creating a new project. Add a label and a picturbox to your form as well as a button. To prove the transparency works give the picturbox an image. Then add this code.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    'Set the parent
    Label1.Parent = PictureBox1
    'Position the label so we can see it
    Label1.Location = New Point(0, 0)
    'Give it a transparent background
    Label1.BackColor = Color.Transparent
End Sub

Resizing Picture box in StrechImage mode and Gradiant problem!!!???

Hi.
I'm making a Button user control and it consist of three parts.
Left,center and right Picture boxes. Why when i change picture box width which is set to StrechImage mode, it's image in runtime will take gradient?

Re: Resizing Picture box in StrechImage mode and Gradiant problem!!!???

JUNEYT13-Mar-07 3:04

It only streches the image. Therefore, you won't be able to apply percise gradient. WTF | :WTF:
