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).

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.

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?

Im working with VB 2008 express
I have several pictures on my form designer and a large textbox to the right of them. When the user clicks the pictures I want a list to be created in the textbox. I was able to get a single button posted into the textbox but when a second picture is clicked it over rides it and replaces it. I wasn't sure if i should be use some kind of loop or not.

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()?

I am having problems creating charts dynamically, using MSCharts.If I drag a chart control into a form, and then use this, I have no problems. However, if I change the code and try to create the chart dynamically, then I just get a blank white rectangle, and no graph, axis or anything.I am trying to create the graph once a user clicks a button. Here is the code I am using.
Public Class Form1
Dim Chart2 As New System.Windows.Forms.DataVisualization.Charting.Chart
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

I would like to dynamically create an object (in my case a thread) and then be able reference that object. Simplistically put, I would like to read from a text file and then process each item using a thread (so that I don't have to wait for each item before starting the next). The problem is that I cannot think of a way to create a new thread dynamically ie. thread name so that I can then wait for all created threads before doing something else.

We use a common web.config file to store all of our database connection strings.
I would like to have a way to read in all of them, somehow create a property or type so that they become dynamically available.
So when I want to create a new sql connection my my class can show the connections strings available.
Dim myconn as new MySqlOps.Connection(MySqlOps.ConnectionString)
so when the user types MySqlOps.ConnectionString. it will give a list of the connection strings read in from the config file.
Not sure how to approach making the connectionstrings available like above.

This may be simple, but im having a tough go at it. I'm trying to make a "review" section in a step through form, where the user can see everything that has been entered and if they choose go back and "edit" that information again. One section only has to show the information that has been added by the user, basically if they don't select a certain checkbox there is no reason to display the info for that box.I want to to dynamically create labels in a Panel (Panel7) on a TabPage (TabPage3), only for the checkbox information that was selected. This is what I have right now, and I am unable to see anything on the page, I have also tried without the panel and straight onto the tabpage itself to no avail.
MsgBox(CurPat, MsgBoxStyle.Critical)
If (CurPat = "True") Then
Dim lblTemp As New Label

I have to create an application that will dynamically add a menu strip with menu items to a form(ie NOT dragged and dropped onto the form) in Visual Basic. The menu strip should be created in the Form_Load event handler. I have to use a TextBox for user input. If the user enters information into the TextBox and clicks on the Add Button, the text should be added to a ComboBox control.A Menu should then be created that must be added to the menu strip dynamically.

I'm making a LAN instant messenger and I'm trying to achieve something similar to how MSN will open a new chatting window when you double click on a friend. My main form has a list of friends, and I want to create a new chat window when they double click on one of those friends. I've created a "template" chat form which I want to generate dynamically, and I've run into some problems I need help with.[code]The form will only appear once as far as I can tell, and the chat form has events such as button clicks; an error occurs when I try to change something like the text property of a label for example (eg. clicking a button on the chat form changes the text of a label on the chat form will cause an error to occur). The error I actually get is:[code]Now, call me a newb if you will, but I really don't know much about threading and all that hocus pocus.

I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.
