So, now I've exactly used this code to load an image from a path specified. Still, i seem to get a blank form when i run. im quite sure about the path and the existence of the file. Also, the exact piece of code is also available at: Draw an image : Draw Image2D GraphicsVB.Net Tutorial So, now do i have to insert a picture box to se the loaded image. Its like.. ive used the graphics thing to draw the image. so i reckoned that picture box was unnecessary.
Forms :: Loading Image Into Picturebox?

View 1 RepliesForms :: PictureBox - Image Loading Using ComboBox
May 14, 2009I 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.

C# - Dynamically Loading .NET Assemblies?
May 25, 2009I am writing a program and I want the program to support plugins. I created an interface that the program must implement. I am using the following code from my main program to call the plugin:
Dim asm As Assembly = Assembly.LoadFrom(ff.FullName)
' Get the type
Dim myType As System.Type = asm.GetType(asm.GetName.Name + "." + asm.GetName.Name)
' If the type is null then we try again without the root namespace name
[code]....
I set this property from my main program and everything works. Except, after a while, m_PanelObject gets set to Nothing for some odd reason. I'm not setting it to Nothing anywhere in my program and there is no place in the plugin code that sets it to Nothing.
C# - Dynamically Loading Assemblies In .NET?
May 24, 2010We've built a small component which takes an Id, looks up an entry in the database for an assembly/namespace/class, and dynamically loads an instance of the class that we're after. It has been working fine up until now, but when running this code in VS 2010, it's failing.
Private Function AssemblyLoaded(ByVal assemblyFile As String) As Assembly
Dim assemblies() As Assembly = AppDomain.CurrentDomain.GetAssemblies
For Each asmb As Assembly In assemblies
[Code]....
But it feels dirty. Is there a better way of checking if an assembly is already loaded, and handing that back to the caller? Are the issues above specific to .NET 4.0 or Visual Studio 2010? I haven't tried this outside the IDE as it requires fairly significant configuration.
Dynamically Loading CSS Elements In Asp.net
Aug 26, 2011I have an asp.net web app that allows users to customize some GUI aspects (such as font color, add a custom logo etc). This information is stored in the user profile database. I have a css file that populates font colors etc. The main page, loads the users profile from the database, and customizes the page accordingly.Aside from having each label with its own "font-color=", how can I display the CSS elements, based on the user profile information returned from the database?
View 3 RepliesAsp.net - Dynamically Loading User Control In MVC?
Sep 16, 2011I have a UserControl.ascx which essentially outputs the Name and Email of the user currently logged in (stored in session variables, for the record) at the top of every page on my website. Said control is currently called by Site.Master using <%Html.RenderPartial("UserControl")%>.
It works fine when I log in for the first time and my details are displayed correctly, but when I log out and try to log in again something strange happens...
The Control itself tests the condition Session("auth"), which my controller sets to true upon authenticating a user and which it forces to false when the logout button is pressed. All session variables are cleared upon logging out.
(For the record, my user control used to check Request.IsAuthenticated rather than Session("auth") to determine the current Session State. The same issue arised.)
The problem is that when I try to log in as a different user, instead of showing the new user's information in the header, nothing appears beside Name: and Email: (see code below). I suspect this is because UserControl.ascx is not updating its state.
Ideally, I'd like a solution which would force UserControl to check Session variables every time a page is loaded. Is there a clean way to achieve this?
<%@ Control Language="VB" AutoEventWireup = "false" Inherits="System.Web.Mvc.ViewUserControl" %>

VS 2008 - Image Transparency - Loading A Bunch Of Pictures On Top Of One Image
Oct 14, 2009Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.
Loading User Control Dynamically Loses Data
Apr 22, 2010I have a created a user control. This user control I dynamically load on a page inside Telerik Panelbar control. I have done all necessary coding to save the viewstate and load this dynamically created usercontrol every time page loads.On this User control I have a asp panel. By default this panel is invisible. When user clicks a button on this user control panel is made visible. On page load of this user control I populate all the controls on this panel.Everything works fine if I dont load this use control dynamically but when I load this user control dynamically and if I make panel visible by default then only all fields on the panel are populated. But if I make by default invisible and on button click make panel visible none of the text boxes or comboboxes are populated. I populate comboboxes on page load of the userControl but inbetween postbacks all the comboboxes on the user control loose data.[code]...

2008 : Listview With Image List - Change The Image In The Listview Dynamically?
Jan 15, 2010I have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.
