I want to create a extension class for the List type so users can do [code]I've it defined as Type and also tried object but neither are accessible when I have a list of strings.If I set it to be string it then appears..But I want something that is more generic and will work with all lists. How do I need to define it?

I am trying to compare the contents of 2 collections in a unit test in .NET using MSTEST. To make things simple, instead of having to .Sort() and then loop through the collection and compare items one at a time, I've found the new and very cool .Intersect Extension method.
It seems to work great by doing:
Assert.AreEqual(expected.Count, actual.Intersect(expected).Count)
However, now that I have a test which needs to be case-sensitive, it breaks. I've tried sending Intersect's second parameter StringComparer.Ordinal,StringComparer.InvariantCulture, and StringComparer.CurrentCulture... no luck..
EDIT: here is the data:
Actual:
(0) "FOO" String
(1) "foo" String
(2) "Foo" String
[Code]....
It seems to be removing a matching duplicate 'foo', and a matching duplicate 'BAZ'. Perhaps there is a better way to assert collections are matching?
_EDIT2: I think Intersect() removes duplicates, which is why this is breaking. I Found the CollectionAssert Class.
I have a custom list that inherits Generic.List and it has a method for deselecting all of the members named DeselectAll It has looked like this for a few weeks and has worked fine.
Public Sub DeselectAll()
MyBase.ForEach(Function(p As Publipostable) p.ModeEnvoiChoisi = Nothing)
End Sub
Today, it stopped working ?!? I reverted to an earlier version using delegates and that works fine...
Public Sub DeselectAll()
MyBase.ForEach(AddressOf DeselectModeEnvoi)
End Sub
[code]....
Edit: Stopped Working meaning it no longer sets the property p.ModeEnvoiChoisi to Nothing on each item in the list. The DeselectAll method gets called, but all the items retain their previous values...
I have an enum and a usercontrol, both in the same assembly (a plain .NET 4 web site). In the Constants class:public Enum CrudOperations Add Edit Delete. This controls the columns in a GridView on a UserControl via a property on the UserControl
[Code]...
In C#, I've specified the columns to show with markup as Mode="Edit,Delete", but in VB.NET, this does nothing. The only way I can get anything to show is with the codebehind, but if on the containing page I use userGrid.Mode = CrudOperations.Edit And CrudOperations.Delete, I get all the columns (there's also a delete column), but userGrid.Mode = CrudOperations.Edit Or CrudOperations.Delete shows nothing.
I am writing an application that has to read and interpret data stored in some PDF files. The reading part is done but I am only able to get a dump of all the words on a page and not the format of the words. What I mean is that if I have to extract a table, I am getting the numbers in the table but not the markup which defines the table.Further, there is some formatting used which displays a few of these numbers within parentheses (meaning that those numbers are negative) but the parentheses themselves are not part of the text. Hence, I am not able to distinguish between positive and negative numbers present in the PDF table!
How do you get the PDF markup along with the text? Is a PDF similar in structure to an XML with tags used to markup tables etc.? If not, then, is there a resource which describes the salient features of the PDF DOM?I am using VBA and the Acrobat library (AcroExch etc.)
Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
Well i have a usercontrol with a property "ClientScript" and in the aspx file where i use the usercontrol i set the value to [code]the problem here is that the is litterly passed to the property and not parsed first and replaced by the ClientID..I had the same clientscript applied to a buttons OnClientClick and there it worked...Must i apply some sort of attribute to the property to get this working? [code] i know that im saving to a local variable and that it will be cleared on reload and so on but thats not the problem here.
View 1 RepliesI want to show a MessageBox in a VB.NET application that has special markup for its text. More specifically, I want to display an unordered list. I tried doing it by wrapping the text in HTML tags (which Java Swing supports for example, if I'm not mistaken) and working with <ul> and <li>. This did how to do it without creating a completely custom messagebox class?
View 1 RepliesIn my classic asp app, I have a markup page with a bunch of checkboxes. The checkbox control ID is bscv.Once a user checks a box and clicks submit, the value is processed on the next page called next.asp.Based on the value of the checked box, I display the correct dropdown.I use the following code on next.asp to display the correct dropdown.
If bsvc = "master" Then
' only master was checked

I am trying to bind a RichTextBox to data from an XML file where text within a paragraph may be tagged with formatting tags. As an example the text may look like this:"The size of the area is 5000 m<superscript>2</superscript>".Text may also contain other formatting tags such as <bold> or <italic>:"The quick brown fox <bold>jumps</bold> over the <italic>lazy</italic> dog".
View 5 RepliesThe way markup works for those that are unfamiliar is similar to html. For example, in HTML, <strong> is bold and </strong> closes the tag. In Markup, [b] is bold and [/b] closes the tag. Similar yet different.My form consists of 1 Richtextbox named RichTextBox1 and WebBrowser named WebBrowser1.In order to use HTML I use the following code:
Private Sub RichTextBox1_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles RichTextBox1.TextChanged
WebBrowser1.DocumentText = RichTextBox1.Text
End Sub
When I make an HTML form for MVC 3/VB with the Razor engine, I would expect to be able to do it like this:
@Using Html.BeginForm("Action", "Controller")
<fieldset>
@* Other form code and values *@
</fieldset>
End Using
But if I do that I get "BC32035: Attribute specifier is not a complete statement. Use a line continuation to apply the attribute to the following statement." I need to add an @ character before the opening tag to avoid this error.
With my recent new project with HTML/Markup generator/editor, I have run into a roadblock. Basically here is my code for replacing markup with HTML. The way this works is that the webbrowser has the same text as RTB1. Since the Webbrowser supports HTML, it automatically converts to the style that is specified in RTB1. [Code]

I'm new to custom server controls and I'm hoping to use them to build various 'modules' for different sites I build to cut down on duplicate code.
I'm familiar with custom user controls in which I can create an .ascx & .ascx.vb file which can then be imported into an .aspx page and used freely.
However, with custom server controls I cannot find a way of using markup/html code. Is this possible at all or must all code be created programmatically?
I downloaded some sample code which includes a database query within the markup code. It makes a query to the database and displays the results of the web form and I would like to divert the output to a text file and I am not sure how to do this?Can this be done from here or would it just be easier to code it in the source and make a new connection to the database?
Sample code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringIP %>"
DeleteCommand="DELETE FROM [ip-to-country] WHERE [ID] = ?" InsertCommand="INSERT INTO [ip-to-country] ([ID], [BeginingIP], [EndingIP], [TwoCountryCode], [ThreeCountryCode], [CountryName]) VALUES (?, ?, ?, ?, ?, ?)"

but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

Using the below code I want to set the '*' to any file. This folder (C:ewtemp) will only have one TIF file in it at a time so I want it to use that file as TextBox1, but that filename is dynamic, but always with extension .TIF.
TextBox1 = Convert.ToBase64String(StreamFile("C:
ewtemp" * ".TIF"))
Know how to do that?
I am having problems with CodeDomProvider. When I compile a code VB, there is not an error. But, if this code has extensions (ex: string().contains(), char().count, char().AsEnumerable, etc.) at the moment that I call these functions, it's returns an exception equal for all these extensions:
'Public Member 'Count' at type 'Char()' not found'
'Public Member 'Contains' at type 'String()' not found'
Dim refs() As String =
[CODE]...
These are the Assembly that is referenced to the compile, and this is also configurated for run in Framework 4.0.
Dim Param As New Dictionary(Of String, String)
Param.Add("CompilerVersion", "v4.0")
Dim oCodeProvider = CodeDomProvider.CreateProvider("VisualBasic", Param)
This code is inside a string:
Imports System
Imports System.Xml
Imports System.Data
[CODE]...
After I use it for compile my Assembly. The code compiles without errors, but when I call the function 'ProcessarLink', it returns me the exception in 'Contains', or when I call the function 'Personalizar' the errors appears with the 'Count'. This happens with the others extensions too, like AsEnumerable, etc.
