Dynamically Creating Buttons With Pictures?

Aug 21, 2009

I am working on a project that requires me to read a table of items, and then display the items as button with a photo for a POS system. Any suggestions on how to implement this? This project is using .NET 3.5 and a SQL Compact 3.5 database as a data store.I am using windows forms over an MDI form.

IDE :: Creating Pictures Dynamically In VB (2005)?

Apr 30, 2009

I've been trying to get some PictureBox'es to appear and disappear dynamically. Here is my code I've been trying to get to work:

Private Sub Container_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Image As New PictureBox

[Code].....

Obviously, this isn't how I started out. But I've been trying everything I can to get it to actually display. If I have a PictureBox with exactly the same properties, it displays when I tell it to. This way, it doesn't. I even created an entire class and used that - nothing. I'm guessing it may be the fact that I used a Dim statement, but I'm still a teensy bit novice-y to certain aspects of VB (in particular, Image handling).

Dynamically Creating Methods For Dynamically Created Buttons?

Mar 15, 2011

I have this code.

Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer

[code]....

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

VS 2010 Changing Buttons Pictures?

Jan 4, 2012

Not as easy as it sounds, I've been doing alot of research on this and I just about decided I can't find the answer, The Goal:I want to be able add a single image to a form from a selection of images with the click of a button, this would probably work much better with java but I know nothing about java so I am using vb

Progress:So far I have decided to just try and find way to change the buttons background image to display the image I want, so I set up lots of buttons in a form with the text "+" which simply means add a photo. Now I binded the buttons to a context strip with text saying what image I can change the buttons backgroundimage to.Questions:I need to know how to make the buttons background image change from the click of one of the options on the context strip. Is this even possible?

Dynamically Generated Buttons?

Feb 8, 2010

dynamically creating buttons with images in them and then accessing the on click event for that button. However lets say for example I have three buttons created during run time, button 1, 2 and 3 for simplicities sake. Each button needs to correspond to a value (lets say one, two and three). The problem comes in when i want to, for example, click on dynamically generated button 3 and have it display "three" in a message box. But button 2 might close the program. How can i reference an event when i don't know which button corresponds to which action..

Add Events For Dynamically Created Buttons?

Jan 14, 2010

My process is as follows:I access a database table to determine what questions to ask (20-100 questions).Each question is display along with, possibly, a "done" button.My code to do this is as follows:


If datareader("Who_Second").ToString = lbl_Your_Position.Text Then
Dim b1 As New ImageButton
b1.ID = "btn_second" & datareader("QCC_Q_ID").ToString

[code]....

What I need to do for each button is strip out what the "QCC_Q_ID" is for that button and insert information into another table of the DB.My partial code for this is as follows:

Sub btn_done_clicked(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
Dim MyDate As Date
Dim QCC_Q_ID, Position As String

[code]....

Two problems:1. My sub is never being called, so I can only assume that my "addhandler" is not working.2. QCC_Q_ID = e.ToString.... That doesn't seem right - is it? What I need to do is get the name of the button (btn_second13) and get just the number out of that (13). Is there any easier way to keep track of that ID?

Dynamically Create Radio Buttons?

Apr 2, 2011

is it possible to dynamically create radio button options that are dependent on a value within a database? For example 'b' is stored in a field so then 'a' will also be a radio button option, 'd' is stored in a database field so then the other radio button options will be 'a', 'b', 'c'....the radio button list will change depending on the value stored in the database field.

Deleting Lots Of Dynamically Created Buttons?

Jun 2, 2012

I'm a new programmer to vb.net, so apologise for what is likely to be ignorance.
I'm building a simple gui for a database interface, with many parent and child items within it. Upon a form I create buttons depending on how many items (parents/children). I've got the creation of the buttons thus:

For RowNumber As Integer = 0 To NoOfRows
Dim Buttoni As New Button
Buttoni.Location = New Point(LocationX, LocationY)

[Code]....

But I'm struggling with a way to delete the buttons to make way for a new set to replace them... I can delete a single one upon its click, but I'd like to delete all of the buttons that have been created in this way before re-creating them.

Dynamically Allocate Group Boxes & Buttons

Mar 10, 2012

I am currently trying to allocate a number of group boxes dynamically. Previously (in other languages) when I have carried out something like this I have used the '&' to substitute the contents of the variable direct into the code I.E

For I = 1 to 20
Groupboxname = "GroupBox"+I
Weatherstates.&groupbox.controlls.add(obutton)
next

This would then have the result of creating a button in all the group boxes, however this does not appear to work in VB .net 2010

I have looked at Directcast, but i am a even more confused. Is there a simple way to substitute the contents of a variable into the code ?

Centering (Perfectly) Dynamically Created Buttons On Form?

Jul 31, 2011

I am currently developing a simple menu application that has a control array of buttons and I am having a hard time with re-sizing the form and centering the buttons. These buttons are created at compile time (with parameters from an INI file) and my current centering algorithm seems to slightly set them to the right. I am using the "button.location = new Point(...,...)" method but after reading about this it says the values locate the buttons left upper corner rather than center, thus accounting for the slight offset to the right.

My two questions are this:
How can I perfectly center these buttons at compile time? I have tried accounting for the difference by subtracting half of the button's width but the button width and point properties seem to be incompatible and the button gets heavily offset.

And... my other goal for re-sizing the menu is to have the buttons perfectly expand and contract when being re-sized. It seems as though anchoring is ineffective when the buttons are created dynamically so I have been forced to write ratio algorithms... Is there a way to get anchoring to work?

Here's what I have in the load up :
MyControlArray(i).Location = New Point(CInt(((Width - ButtonWidth) / 2) +_
(ButtonWidth / 2)), CInt((Height - MyControlArray(i).Height) / 2))

I have already tried:
New Point(CInt(((Width - ButtonWidth) / 2)), CInt((Height - MyControlArray(i).Height)_
/ 2))

Forms :: Adding Tool Strip Buttons Dynamically?

Apr 30, 2010

I need to be able to add buttons to a tool strip at run time. As of now I've been able to get the buttons to display with a nice little picture just how he wants and some text under it. Just can't figure out how to "enable" the click event for these buttons. Obviously I need them to do something rather than just sit there looking good and this is where I'm stuck. Right now I'd be happy for a message box to come up saying yep I'm working as I could then work with that. This is what I have for code so far... this is just to get it working I'll work on the actual code later.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim btnSomething As New ToolStripButton
btnSomething.Text = "Test 1"

Panels / Tabs And Buttons (which Are What Need To Be Rearranged) Are All Dynamically Generated

Mar 11, 2011

To set the scene, I have implemented a drag and drop rearrange in a FlowLayoutPanel (thanks to a few good Tutorials) which worked absolutely fine until the client decided that he needed many Panels each contained in the Tabs of a Tab Control.Ironically the FlowLayoutPanel rearrange still works if the panel is not in the Tab Page. However the moment it is it stops functioning completely.In all honesty its probably a simple issue that I'm missing but I can't seem to find an answer. I'm certain that the issue is in the following block of code, most probably in the following place:If controlcoll(i).Bounds.Contains(mouse.X - flow.Left, mouse.Y - flow.Top) Then Either that or in a property of either of the controls. [code] The Panels, Tabs and Buttons (which are what need to be rearranged) are all dynamically generated.

Creating A Byte() Dynamically?

Aug 6, 2009

I am working on a simple windows app that will take our TripleDESCryptoServiceProvider Key and IV from a file and use it to Encrypt and Decrypt strings, etc...This works great and has for years in a utility program, but I want an easy app that can read the Key and IV...following format in the txt file:

[KEY] {123,123,123,123,132,132,123,...}
[IV] {23,23,23,23,23,...}

And then create the Encryption Pair...Currently I have the following

clientDESCryptoServiceProvider = New _
TripleDESCryptoServiceProvider
clientDESCryptoServiceProvider.Key = New Byte() {111, 222, 333,...}
clientDESCryptoServiceProvider.IV = New Byte() {1,2,3,...}

Is there any way to pull the {111,222,333,...} and {1,2,3,...} from a text file and create the Byte() that is required?I can read the info from the text file, but cannot seem to create the right format for generating the Byte()?

Dynamically Created Event - Button To Simply Set A String Variable Equal To The Clicked Buttons Text

I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.

I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.

How can this be accomplished?

Dim strMenuName As String
strMenuName = dr.Item("strMenuName").ToString
