I am having a problem accessing my resource images. a brief history, my image name is the same as my item name I want to display the proper image with the associated item in a data grid, as I loop through and load my datagrid I need to combine "My.Resources._" with the item number to correctly associate the proper image.

What is the best way to provide strongly typed access to the session object? I am planning on turning on Option Strict, which is causing the compiler to complain about my lazy programming technique of directly accessing the session object:
Dim blah As Integer = Session("Blah")
My initial thought is to create a class that wraps the session and provides strongly typed properties for the information stored in the session. However, I cannot decide if the class should be a singleton, or instantiated on every use, or where the code should reside (i.e. within the web project or within a class library).
I'm leaning towards a singleton in my class library, but I don't know if that is the best solution, or if I am missing any other possibilities.
Proposed Solution:
Public Class SessionAccess
Public Shared Property Blah(ByVal session As HttpSessionState) As Integer
Get

I've read that the VS 2005 IDE can automatically create strongly typed resource files. How is that accomplished?
View 2 Repliescan we use images in the resource folder as background images by setting the background image during run-time by coding?
View 5 RepliesI've been coding using vb.net for a while but I've been using imageLocation property to set an image for a picturebox or for the background image of a form. How do I use those images in my Resources Folder in my solution explorer to set an image for a certain picturebox or form. I sorta need a code for it.

In a VB project I can add a resource via the project properties resources tab, or I can right-click the project in the solution explorer, click add, then click add existing item. What are the differences?If I want to add a DLL file and include it as an embedded resource, do I have to add the file via both methods? Only one?
View 1 RepliesWhenever I delete a Resource from my Resources folder, I get an error. How do I fix that?
View 4 RepliesWithin a Visual Basic Project I have added a resource file (resx) that contains a bunch of images.Now I want to query the names of the images.If I open the resx file in the designer view in the Visual Studio IDE and select an image, the property grid shows me a name property (defaults to "filename without extension but can be changed).The background is that I have a imagelist that is created at runtime and populated with the images from the resource file. To be able to access these images by the key, I have to set it.My code looks like this (everything hard coded):
Dim imagelist as new Imagelist
imageList.Images.Add("A", My.Resources.MyImages.A)
imageList.Images.Add("B", My.Resources.MyImages.B)
[code]....
And I want to achive this:
Dim imagelist as new ImageList
For Each img in GetMeAllImagesWithNameFromMyResourceFile
imageList.Images.Add(img.Name, img.ImageFile)
Next
where Name is a string and ImageFile a System.Drawing.Bitmap
I am creating a project in which i need a background image for every form in VB 08,initially i took the images as embedded resource and had a problem so then i replaced them as local resource, now,my question is that when i install my project on different computer will it display the background image.
View 3 RepliesI'm pretty sure this is something super easy, but how do i access a resource that is in a separate project using the expression syntax?I thought it would be like so:
<%$ Resources:SomeNamespace.Resources.Web, PleaseSelectAnImage %>
where SomeNamespace.Resources is the project that the resources are located in.
i normally just do <%= SomeNamespace.Resources.Web.PleaseSelectAnImage%> but i need to have this inside a control. <kw:SlickUpload ID="SlickUpload1" runat="server"
ValidExtensions=".png, .gif, .jpg"
InvalidExtensionMessage="<%$ Resources:SomeNamespace.Resources.Resources.Web, PleaseSelectAnImage %>" >
so when i just do what i normally do, it puts <%= SomeNamespace.Resources.Web.PleaseSelectAnImage%>" literally.my project name is SomeNamespace.Resources. the resource file name is Web. and the key is PleaseSelectAnImage.
I'm using EF 4.3.1 in VS 2010 (.Net 4.0) to load a number of reference tables from a database in order to bind them to controls in a WinForms app.At form load, I'm pre-fetching the data so that it's stored locally, and I'm creating a dictionary of BindingSource objects that I can use to bind the local data to the controls.The intent is to minimize the impact of the EF's self validation on a cold query in order to load forms faster and improve UI responsiveness.I've written code to create and fetch the BindingSource object for a given DbSet collection as follows:
Private _dictBindings As New Dictionary(Of String, BindingSource)
Private Sub ValidateBinding(Of T As Class)(ByRef DbCollection As DbSet(Of T))
Dim strClassName As String = DbCollection.[GetType]().GetGenericArguments(0).Name
If Not _dictBindings.ContainsKey(strClassName) Then[code].....
However, I'd like to call ValidateBinding on all DbSet collections in the Model on startup, and I'd like to use reflection to iterate through the available collections in the context because we're currently loading 66 tables and could add more later.I've written the following code:
For Each propSet As PropertyInfo In Db.GetType.GetProperties(BindingFlags.Instance Or BindingFlags.Public).Where(Function(P) P.PropertyType.IsGenericType)
ValidateBinding(propSet.GetValue(Db, Nothing))
Next
but it won't work as propSet.GetValue() returns an Object instead of DbSet(of T).I also can't cast the object to a DbSet of the appropriate type, even though I know the type through reflection.I don't have access to the C# Dynamic type,and I know it's a pain to mix generics with reflection, but is there a solution for which I can pass in a reflected DbSet to my functions?Perhaps something using Method.Invoke?
In a vb .net winforms app I am trying out something for "wide and shallow" children of a record. I use strongly typed business objects ( Strataframe ).My plan is to have a number of "child tables" collected in a dataset I drop on the form. they have no correspondence in persisted data, so the dataset is untyped and I am creating the schema through the property sheet for the tables. Each table is the datasource for a datagridview in the interface.
In my proof of concept sample, My main businessobject (CustomerBO) interacts with a SQL Server 2008 table with fields - pk, name, - and a third column which is currently varchar(max) as I considered XML but could just as easily be varbinary(max) if that works better for holding the serialized dataset.
bo.bigfield will be the strongly typed prop I want to hold the byte() array or XML or whatever that represents the dataset for that record.So, the question in a nutshell - how do I convert a dataset to a single datum and reproduce the dataset from that datum. This is my first foray into datasets, datagridviews as well so if there are better ways to accomplish any of that I'm listening.

View 3 RepliesI have a situation where I have an xml document that has a bunch of elements that I basically use as data variables. I populate the variables from various sources and then transform the xml file to an html file for user viewing.having to remember the names of all the data elements in the file is somewhat tedious. Is there a way to generate a strongly typed xml document object so that one can simply dot into the various data elements?
View 5 RepliesI have a simple windows Forms application where in I have a usercontrol called "MyControl" derived from PictureBox.
In this MyControl, I have the following code :
Sub New()
MyBase.New()
Me.BackgroundImage = My.Resources.MyImage 'This is a project resource image
End Sub
Now when I drag and drop this MyControl into a form, I get the image and also those stuff. But the problem is that the BackgroundImage is being copied into the Form's local .resx file.So when I look into the form.designer file, I find the following :
Me.MyControl1.BackgroundImage = CType(resources.GetObject("MyControl1.BackgroundImage"), System.Drawing.Image)
This is a problem and also when I try to change the image in the control, it does not get reflected in the form's control instance.
How do i write the path to my resources files?[code]....
View 1 RepliesI have added a .png to my project (in solution explorer). Now all I need to do is simply point a picturebox at this resource and display it.
I'm obviously missing something quite primitive! I assume that would be classed as a 'resource' ? I don't want to load images from file paths, it just makes it messy for the user + they could technically change what is displayed within the program.
I am currently working on a project that contains a few images, that are placed in a lot of different controls. I was wondering, is it possible to rename those few resources images , ex. image1 name is bg, and when i click a button to rename that image to bg2 and rename bg2 to bg.. something similar to an image swap, just done by renaming resources. I will wait for a few suggestion, but if all lead to the same possibility, which I hope is not "no, you can not", than my time is narrowed down for better use, other than changing each control's image manually..
View 9 RepliesI'm trying to populate a set of 9 PicturBoxes with images selected at random from a set of 54 held in Resources. The random selection poses no problem but getting the images to display is proving troublesome. My initial problem was that I can't just use a string variable to identify the image in VB.NET.
However, Deepak Sakpal has given a good pointer in answer to another post which looks good. The code runs ok and completes without any runtime errors, but sadly it displays no images. All (54) images have their Build Action selected to Embedded Resource, the image name concatenates correctly.

I have about 10 .png images in my.resources that I want to show in a Combobox, without any text. They're all slightly different sizes, so want them scaled to 40 pixels high x whatever the scaled width is.
When the end user selects an image in the Combobox, I want to store which of the my.resources items was selected to be saved so that I can then use it later on (for example, I want to save the value in my.settings, so that I can repopulate the combo box with the chosen image on next load).
I know how to load images into a combobox, but am having problems with the scaling - I also can't figure out how to load images from my.resources (it's easy with an imagelist, but how do I do it from my.resources?), or how to reference the selected resource for later use.
I placed some images in my Resources directory, how can i load this using a picturebox? PictureBox1.BackgroundImage =?
View 1 RepliesI have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
imgItems.Images.Add("A", My.Resources.A)
imgItems.Images.Add("B", My.Resources.B)
imgItems.Images.Add("C", My.Resources.C)
imgItems.Images.Add("D", My.Resources.D)

I'm trying to make a Blackjack game in VB. What I'd like to do is populate an array with each of the cards so that I can randomly generate integers and use those integers to pull an index from the array, basically randomly selecting a card. My problem is that I can't seem to get the images in the resources folder to go into the array. I'd like to use a For/Next loop to populate the array, as I would rather not manually assign all 52 cards to the array. I'm trying to do it like this:
Dim CardArray(51) As Image
Dim LoopIndexInteger As Integer
For LoopIndexInteger = 0 To 51
CardArray(LoopIndexInteger) = My.Resources.ResourceManager.GetObject(LoopIndexInteger)

I want to use the image.source property to reference or retrieve .jpg images from the Resource file at runtime so I can dispay them in an image control, but seem to be failing. The images are now in the Resources file. I use vb.net in WPF. I know how to reference them in a folder but this proves to be inconvenient.
View 2 RepliesI am trying to use a combobox that when a user selects an item than that particular item (image) is drawn on the form.
View 4 RepliesOk, here's my problem. I already understand referencing a image using My.Resources.(Image name), But this won't work for my current situation, because the image name is in a string so I can't Hard-Code it into the program. IE. The file name is found by doing the statement:Filename = "_" + poke + "_"
Where poke is as string that contains the name of the file. The normal way to call this would be to use My.Resources._(contents of poke)_ but that doesn't work since i can't just inject the contents of poke into the line without making the entire thing a string, and by making it a string that command doesn't work normally.
I just can't seem to find a guide anywhere that talks about this, and I've been stuck on this for quite some time now. I've been able to reference XML's that are included the same way as the images using My.Resources.Resourcemanager.Geobject but this doesn't seem to work for the Images, and I haven't found any other way.
