Forms :: Subrutine To Handle ALL PictureBox?

Apr 9, 2009

I have 50 pictureboxes in one form. I need to write the same code for each one.one is to write a function for each PictureBox handling each object induvidually two is to write a function for all PictureBoxes that handle ALL object, but I have to declare each object in the Handles syntax of the subrutine as follows:

Private Sub PreviewTile(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PB1.DoubleClick, PB2.DoubleClick, PBChapel.DoubleClick
DrawBorder(sender, Color.Wheat, 3)

[code]....

I was wondering if there is a way to write a subrutine that will Handle ALL Pictureboxes without having to enumerate them.example

Private Sub PreviewTile(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.PictureBoxes.DoubleClick '<-- made up
DrawBorder(sender, Color.Wheat, 3)

[code]....

Forms :: How To Handle Form Load

May 17, 2009

I had created a form(MDI Child) which have 3 to 4 dataset on it. They all are loaded from the database at the form load event and therefore takes too much time to load and show some part of form during that time. When it load completely it shows the whole form. Is there any way that user will see the complete form instead of some broken form.

VS 2010 Handle Event From Different Forms?

May 30, 2012

I have an event in a module, like this:

vb.net
Module Module1 Public Event Event1(Value as Boolean)End Module

I want to be able to handle this event from different forms. This is what I tried to do...

vb.net
Public Class Form1 Private Sub Event1Handler(Value As Boolean) Handles WindowsApplication1.Event1 End SubEnd Class

But I get a squiggly line under WindowsApplication1 that says Handles clause requires a WithEvents variable defined in the containing type or one of its base types. I tried to swap Module1 in, but same thing. I tried without anything in front of Event1, but still nothing.

Forms :: How To Handle Each Variable Type Individually

Apr 11, 2010

I have defined 5 variables T1, T2, T3, T4, T5 As Double and set them all = 0. On a form I have a enter information button. Each time the button is pressed I want to assign a different variable, to a text box input. For instance, If I enter 1 that will become T1, and then if I enter 2 and press the button again, that value becomes T2.

I have tried
If T1 = 0 then
T1 = textbox.text
End if
If T1<>0 And T2 = 0 then
T2 = textbox.text
End if

I have tried to use 'else' statements and all kinds of things like that to no avail. I can get the first two variables correctly assigned but three is impossible with my current understanding. Is there a way to do this, or do I need 5 buttons, so that I can control which variable is assigned? To be correct my intent is to create an observation with three variables each time the button is pressed.

For example, the first button press will result in three variables being assigned a value other than 0; they are T1, B1, and R1. I have just begun to understand the concept of arrays and am wondering if that may be the way to go in this situation. I was just going at this in a newbie way I'm sure and trying to handle each variable type individually, and figure out all the T* variables and move onto the B* variables.

Forms :: Load Event Only Fires One Time (Loosing Handle)

Jul 17, 2011

I have a form for which the form load event only fires one time. When the program starts. It will not fire again until I end the program and restart. I have tried .show and .showdialog, but it acts the same. I have read about form load events loosing the handles, but my code looks exactly like it should.

Here is the load event code
PrivateSub frmBilling_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
LoadClients()
LoadTherapists()
LoadCPT() EndSub

Here is the code that calles the form.
PrivateSub BillingToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BillingToolStripMenuItem.ClickfrmBilling.Show()
frmbilling.show()
EndSub

Nov 24, 2008

this is so simple its embarrassing to ask. How do you display a picture in a picturebox? I want to have a static picture displayed on my single form application.

Forms :: Does VB.Net Support Picturebox Arrays

Dec 22, 2009

I am trying to design a basic version of spaceinvaders. I have 6 pictureboxes on my form and the idea is to add a value to the picbox.top property that moves the boxes down at a certain time and speed that i have set in my timer control. The problem i have is i am trying to set properties for all the pictureboxes at the same time by using arrays.

An example would be
dim mypic() as picturebox = {pic1, pic2, pic3, pic4, pic5, pic6}
pic1.top = 10

Forms :: PictureBox - Image Loading Using ComboBox

May 14, 2009

I have a picture box on my form along with a combo box with a number of different options. So anyway when a combo box item is selected I want it to look in the dataset for the selected item's row and pick out the image to load and then using an IF statement it sets the image (or should).

Dim RaceImg As String = DS.Tables("tblRaces").Rows(ID).Item("RaceImg")
If RaceImg = "AusGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/AusGP.png")
ElseIf RaceImg = "MalGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/MalGP.png")
End If

I have tried a number of different ways to get this working, I have tried them in the resources for the program and also tried the following code
GP_Picture.Image = "./Track Images/AusGP.png"
It seems like the picture box isn't redrawing or something? Just to add it will load the first image which is the AusGP because thats the first option in the combo box, after that none of the others will load.

Forms :: Resize A Picturebox To The Image's Size ?

Jun 1, 2010

I'm currently in the process of making a dynamic signature generator, and I want to make the user be able to see what he would get... So I thought of putting a browse button and allowing them to load up a background image for their signature, but I also want the picturebox to resize according to that image's size. I need them to be the same size because of the image's X, Y are needed for the signature.

So I'm using this code for that:

LocalMousePosition = PictureBox1.PointToClient(Cursor.Position)
xy.Text = ("X=" & LocalMousePosition.X & "," & "Y= " & LocalMousePosition.Y)

It works fine, but it only gets the coordinates for the picturebox, not the actuall image, so I think if the picturebox is the same size as the picturebox it would get them just fine..

Forms :: PictureBox - Image Packaged In The .exe Rather Than Using The File's Extension

Feb 2, 2010

Currently I'm using a picturebox object in a program which is referenced to a location on my local computer ie "PictureBox.image = Image.FromFile("c:/image.jpg")". I would like the image packaged in the .exe rather than using the file's extension. So if the exe is copied to another computer it will display fine. How can I do this? I was able to do this is the drag and drog editor by importing an image rather than specifying a location, but for my purposes I'd like it done programmatically.
