I understand that we can set the various style attributes from code behind using :
divControl.Style("height") = "200px"
But how to set it's class instead of declaring each of the styles from code?
I need to create unit testing project for my current website. The currentw ebsite si written in VB. All unit testing examples are using interface to create mock object.

I have a very simple class that is located within my App_Code folder in my VS2008 web application project. I am trying to instantiate an instance of this class from my code-behind file. Intellisense does not seem to be seeing my class and I am not sure why. I am using VB.NET which I am admittedly not that familiar with as compared to C#. Perhaps I am missing something. I would bet it has something to do with something I am missing in VB.NET.Here is my simple class (for testing):

I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

I've been working on a project the last couple of day with the help of a lot of you out there. I've more or less finished the design of the interfase, but there are stange this happening with the form. I can say much about what is wrong because I dont understand it, but I would like to. I have added the form Class code and the Designer Code, is that enough or is more required? Theres a msgbox that popup in the form Load event which I placed there to see what I could learn about the GraphicsBuffer.

I created a VB.NET Class, and created a strong key, and added it to the GAC using the GacUtil. That part has gone smoothly. The Assembly is installed in the GAC and seems to be installed/configured correctly.FYI, the assembly is a Class called Tester, that exposes one public static method called HelloWorld, which returns a string, "Hello World".The next step was to create a test web application (VB.NET and ASP.NET 2.0), using Visual Studio 2005, Windows XP SP3. I created the test web application and added the following to the web.config file's configuration section.
<assemblies>
<add assembly="BenGACTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=3e5b6cecb56999ca" />
</assemblies>
I then added some inline code to my aspx page as follows:
<div><%=BenGACTest.Tester.HelloWorld()%></div>
When I run the page in the web browser, indeed everything works as expected. The page outputs "Hello World" and all seems goodHowever, I don't know how to use this code in the code-behind page.I try to import the assembly, just like "imports system" and it doesn't appear in the IntelliSense.Also, when I try to add the assembly as a reference to the project, the assembly is not found in the list of installed assemblies. I believe this is because the list is pulled from the registry, not from a dynamic list of installed assemblies.My goal is to add the assembly via the web.config file, not by adding it as a project reference, and to use the assembly in the code-behind page.

I am new to vb.net and would like to be able to convert the following code to it's own function - either inside the current module or better yet in a seperate class.This code currently runs in the KEYPRESS event and ensures only numbers, decimal point, 2 decimals etc. are entered and not letters.

I want to be able to create and destroy these child forms as I use the main form. I decided to create a class of the child form, with its own constructors and destructor. When I tried to do this using the Class Library Module, I could not access the Windows.Forms class to create a form.

I am having trouble with this project I am working on. I am a beginner to vb and have some background in access databases. I will attach my am doing an inventory project. When you execute the form, a main form pops up that allows you to choose Production or Inventory. My issue is with the Production. In the production form that pops up after clicking Production, there are text boxes to be filled out by the user based on the production run.plementing a class that will give the box count based on the box type entered. I have to use a class based on the project requirements.
Basically to calculate the usage, enter in a random number for Pods Produced, then enter in a box type (which is A box, B box, C box, D box, Master Case). I want the Public Class Box Count in the code to be able to be placed in the production form's main class code and calculate the box count based on the box type entered. If A box, box count should be 50. If B Box, box count should be 100, If any other box is typed in, the box count should be 150

Is it possible for a class of exposing a type for function returns, without allowing users of that class to create variables of that type? A couple usage scenarios:A Fluent interface on a large class; a statement like "foo=bar.WithX(5).WithY(9).WithZ(19);" would be inefficient if it had to create three new instances of the class, but could be much more efficient if the WithX could create one instance, and the other statements could simply use it.A class may wish to support a statement like "foo[19].x = 9;" even when foo itself isn't an array, and does not hold the data in class instances that can be exposed to the public; one way to do that is to have foo[19] return a struct which holds a reference to 'foo' and the value '19', and has a member property 'x' which could call "foo.SetXValue(19, 9);" Such a struct could have a conversion operator to convert itself to the "apparent" type of foo[19].In both of these scenarios, storing the value returned by a method or property into a variable and then using it more than once would cause strange behavior. It would be desirable if the designer of the class exposing such methods or properties could ensure that callers wouldn't be able to use them more than once. Is there any practical way to accomplish that?In formulating a question, it's difficult sometimes to draw the line between complicated usage cases, and simpler usage cases which aren't quite so important. Here's another usage case, and one closer to the one I'd be most interested in (though I'm also interested in Fluent chaining; being able to have something behave like a C++ reference to a value type would be nice, but probably too much work to bother with).I have a type which is somewhat like the Windows registry, in that it is a hierarchical collection of items, each of which may have a string value, an integer value, and/or a nested collection of items. I wish to be able to support the following types of usage:[code]As for the Fluent interface, my thought would be to have the WithXXX properties return a new instance of a derived class which shadows (not overrides!) the WithXXX properties with versions that simply modify the current instance. The return object from WithXXX would be known to be of the derived class, and would thus use the shadowed WithXXX methods, but once it was assigned to a variable, it would be regarded as an instance of the base class, so the next WithXXX would create a new instance.
C++ a stronger concept of value types than C# or vb.net, including the very useful concept of references to value types; it ensures that references to value types cannot be persisted outside the scope of the type in question. Unsafe code in C# can use pointers to value types, but they don't have the protections offered by C++ references.
I have the following on my interface / webform: <div id="mydiv" class="forceHeight" runat="server" />
now I have a dondition in my code behind where if a certain situation is true I need to remove the forceHeight class from this control. I know in C# you can use:
mydiv.CssClass.Replace("forceHeight", ""); I'm not so sure how you do this using VB? Intellisense doesn't offer me this option?
I've created a custom class that I've grown rather dependent on in my coding. I've encapsulated it as it's own "Solution" and use a reference to the class module within the solution on most of my new projects, and that all works fine. It seems slightly clunky to me that my encapsulated class module is packaged with solution-related directories and so forth. For me, this seems to make management and maintenance of these little class modules difficult (renaming them for instance). So now, a few questions:
When you recognize you have a useful class embedded within a solution:
1) What's your method for encapsulation? (is there a template you like?)
2) How do you organize/arrange your code libraries?
3) When, if ever, might you consider using that "Code Snippets Manager" thing in the IDE?
I'm struggling a bit trying to understanding how Visual Studio wraps-up everything in what appears to be a "Solution" umbrella. There doesn't seem to be a lot of write-ups on how to go about organizing your code libraries to work well within this Solution/Project Visual Studio framework.
