Extended Methods To A DLL?
Feb 27, 2012
I created a couple of extended methods in a VB.NET module. I put them inside a Class, built it and got the DLL. From another program I made a reference to that DLL and imported it using Imports as well.The extended methods appear in IntelliSense and it works but a warning appears in the Error console saying,Could not resolve this reference. Could not locate the assembly "nK0deExtendedMethods". Check to make sure the assembly exists on disk. why this error occurs even though I have referenced the DLL?
This is the Class where I've put my module with the extended method.
Imports System.Runtime.CompilerServices
Imports System.Drawing
Namespace nK0deExtendedMethods
[code]....
And I'm having another doubt. In the Imports statement, I have to mention the DLL's name along with the Namespace name. Like this,
Imports ExtendedMethods.nK0deExtendedMethods
Normally you only have to import the Namespace's name, right?

I've seen extended .NET method libraries such as this and this.In VB.NET, since you create your extended methods in a Module, How do I make them into a DLL?? (like in those links above) Its not possible to build and get the DLL from a Module.

In VB.NET or C#, is there a way to determine if a class has been extended with extension methods?

This is the original code in c#
public class CategoryRepository: RepositoryBase<Category>, ICategoryRepository
{
public CategoryRepository(IDatabaseFactory databaseFactory)
: base(databaseFactory)
[Code]...
Does anyone has an idea what i should change to let it work and let my UserRepository use the methods in RepositoryBase while implementing the IUserRepository?

I am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?

In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.
veryLongVariableName.Id = datasetVeryLongVariableName.Id
veryLongVariablename.Something = datasetVeryLongVariableName.Something
etc.
Using VB.NET's With keyword can help.
With veryLongVariableName
.Id = datasetVeryLongVariableName.Id
.Something = datasetVeryLongVariableName.Something
End With
Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:
With veryLongVariableName As a, datasetVeryLongVariableName as b
a.Id = b.Id
a.Something = b.Something
End With
I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!

I made a simple extension of the PictureBox control. In retrospect, this might not have been the best starting point, but that's currently irrelevant. This is the first time I have tried extending a picturebox control. The point of the exercise was to attempt something odd, but I haven't even gotten that far. The control shows up in the common controls panel, and I can drag it onto the form, but it doesn't get added.
What am I doing wrong? There is very little code behind the new control at the moment, as I am just trying to test a concept, and what code there is doesn't actually get run because the control is never created, so NO code gets run.

I am currently writing a program with Visual Basic 2005 to talk back and forth to an external machine over UDP/IP. I recently had some trouble with it which I got help for today. I need to send the information to the machine using ASCII. I had it figured out so I could send HEX numbers 20 through 7F to the machine. The problem I had and got help for was writing the HEX numbers 0-19 to the machine. The help I recieved said that instead of writing the actual HEX number into the machine, "70" for example, I should write Chr(112). This allowed me to send numbers like HEX 01 by simply writing Chr(1).
My new problem is that I need to write the HEX numbers 90, 91, 96, and 97 to the machine. Every time I try and send these numbers my computer sends out a weird number. For example, I try to send HEX 90 as Chr(144) and it ends up coming up as HEX 3F on the opposite end. After looking up the ASCII table online I found that Chr(144) is an Extended ASCII code.

I've been reading up on this whole subject, but I never came across this specific problem. I already understand that the whole idea of serializing an entire form is a horrible idea and just doesn't work. But, I am encountering a bit of a different problem. I have a class that inherits the "button" form object, that I call DataButton.
Now for my problem. I want to be able to serialize this class, but I don't need any of the information from the actual button class. Is there any way to bypass the fact that I can't set the button form object to Serializable() and notify VB that when serialization is to occur, it should simply skip over that information? Theoretically, if such a procedure were possible, I'd be able to do the entire serialization without a hitch.
I came up with the idea earlier of removing the "inherits" feature from the class, and having simply a button within the class, but that makes my program really difficult to work with as I am constantly changing the location, size, backgroundImage, text, and whatnot. Thus, immediate updates would be much tougher to work with.

I have created a little demo application which is able to create a meeting request by using the Exchange WebService (EWS). I would also like to add some custom properties to this item but up to now I have only found examples which use the Exchange Managed API, which I won't use. There must be a way to create these properties by only using EWS... Does anybody know how and can provide a little code example?

i'm working on an extended combobox control that adds it's items in sub new.
it works but for some reason the form's designer.vb file has an addrange line for the combobox, that results in the items being added twice.
does anyone know how to fix this?

I downloaded the extended webbrowser control created by Matt Kleinwaks (thank you for sharing that).I am using the control to fill out forms on a website. The website uses a popup that contains an html form. The popup form will not close if I click the the html submit button or the close button (it does when using a regular browser). The bigger problem I am having is that when the popup reopens, it contains data in the html boxes that was I have already submited on a previous iteration of the popup. Like it is being cached or something. I am wondering if this has to do with the html buttons not working properly.I basically hit submit on the form, the browse rcontrol hangs up, then I close the form manually. Is there a line of code or something I can add to get it to work right? Like clearing a cookie or disposing of the popup form after I close it?

I have to make an HTML editor and I need to search the rtb for, let's say "<HTML>" tag and what's between them,
Search for: (I type <body>)
Till: (I type </body>)
Rtb text:
<HTML>
<HEAD>
CBA
</HEAD>
<BODY>
ABC
</BODY>
</HTML>
It returns ABC...
The basic idea is to find <BODY> tag and look what's after it till the </body> tag, is that possible?

I was using AxSHDocVw in my program then one day I noticed Navigate2 stopped functioning. Same code worked one day, but then it stopped.
So I found kleinma's Extended WebBrowser control, which I was able to implement nicely. Then I noticed a couple of issues with that.
First Javascript close doesn't close: That is ok, No big deal there.
But the part that I just realized breaks a fairly significant feature in my program.
Before I could execute Javascript with a line of code like: WebBrowser1.parentWindow.execScript(Script, "JavaScript"), but this doesn't work now.
I used this to run ieSpell to spell check in the browser window.[code]...

I'm Alan and I'm writing a little program (beginner), but I'm stuck and I can't get any further. So I hope one of you guys can help me solve following problem.Let me explain what I'm making, so it can give you all a better perspective.
For a this project I'm receiving data via the RS232 communication port. So basically I receive bytes. These bytes are converted to a string. So for example I receive this:"BAA" this is good because I can get the correct decimal value for "B"(66) and "A"(65) using the command asc("A") in .NET.but sometimes I receive a character that exceeds the 0-127 limit for example ""(128) (please see [URL]..But now when I try to get the decimal value of "" I get 63 instead of 128. I searched the Internet and forums for an answer but I didn't find one that fits my problem.
So if it's possible, can one of you code experts explain me how to fix this problem ? It would help me a lot. I hope I described my problem clearly, but if there are some questions,

I am trying to locate the runtime install for Visual Basic 6 Runtime Extended Files. I am not a developer just the guy truing to get it onto the systems for them. My question is simple anI hope the answer is the same. We are converting our systemsfrom Windows XP to Windows 7 and we need the extended runtime modules so a number of our applications will actually work.
I cannot locate the install for this in the Visual Studio download area. Is the re-distributable part of the studio install (so it should be on one of the developers systems) or do I download it from somewhere else.

I want to explicitly inform my user that they are not allowed to use any characters from the extended ascii character set (128-255). When I try to create a string of these values using the following [Code] It outputs them fine, with the exception of a bunch of blanks in certain areas(I am assuming these characters are unprintable), but I noticed that when I hover over the value of sVal in the VS, the tooltip/quickview of the value is written nicely on one line. Any ideas how to remove characters that would appear to be blank spaces (unprintable) when outputting this list?

I am using StreamWriter and StreamReader in VB.NET 2008 Express to read and write ASCII text files. When I create the file and later read it, there is no problem, because I use System.Text.Encoding.UTF8 on both the write and read sides, so extended text is handled without problem. But sometimes, I have text files come in that are just straight 8 bit ASCII without the Unicode BOM... and they get a lot of junk when I try to read in anything with extended ASCII characters in it. It seems like the 8 bit extended characters are translated into multi-byte codes, and since they are filenames, of course, that doesn't work. Since the filenames just have straight 8 bit ASCII filenames. I have tried all sorts of encodings, and nothing seems to work.
The most common character that causes a problem is an "a" ... it is used in a lot of proper names. The funny thing is that sometimes is seems to workout... is there a way to read these types of text files? Some way to just tell StreamReader not to decode the text, just treat it as straight plain 8 bit ASCII text (with the old IBM PC mapping, I think). The one thing that works is to manually edit the input, replacing the extended characters with their un-accented partner and then renaming the files to match the new spelling. Maybe I should just go to read them as byte input and breaking the lines apart in my code.

I was trying to Validate characters (the extended ones) and i see that in various PC's they have in deferent places the extended characters. I meane we are not see the same ASCII code number for a certain character (not in Latins). Now My issue is what i have to do when my program starts to use always a certain ASCII code table? For extended character of course.

I am using TPT modeling and writing the EDMX by hand as our data model is much more complex than the designer can support. My model includes a ProjectObject which has a dependent object name Project. When I query ProjectObject.OfType(Project) using Linq to SQL, I receive back data in all the fields that are inherited from ProjectObject, but no data in the fields that only in Project. I have ran a SQL Server Trace and captured the actual SQL and ran it using SSMS and it returns data there, so I am relatively certain the data is being passed back, but it seems to be getting lost somewhere in EF. Everything appears to be ok in my model, but . . .
