View 2 RepliesIn c# asp.net mvc I can declare some public class like:
public class Foo {
public static string Bar {get
{return "bar";}
}
}
and access it from any html like:
<%=Foo.Bar;%>
right?Well, I have to do the same in ASP.NET MVC VB.Net but I cannot access any variable or method:
public class Foo
public Shared ReadOnly Bar as string
Get
[code]....
UPDATE:standard VB.NET puts modules in the namespace defined in your project.I had to type
MVCApplication1.Foo.Bar
how to create a module that doesn't wrap this into a namespace? Or have the view import the application namespace by default?
I have a sub (Sub 1)that passes a control to another sub (Sub2) Sub2 only knows that the control will either be a picturebox ("Pict1") or a rich textbox ("Rchtxbx").I want to put code in Sub2 that does the following if the control that is passed is aPictureBox:ictureBox1.Load("C est.bmp")However I don't know how to do this as when I type in "x" in Sub2, it does not default to the PictureBox properties and methods.Is it possible to use the name of a control and wrap it in some sort of ControlType() enclosure that identifies its type and grants access to its properties and methods?

I am currently exporting from a DataGridView to Excel by looping through all the rows & columns in the DGV, which is very slow when you have a lot of rows. Here is the code I currently use:
For i = 0 To Me.DataGridView1.Rows.Count - 1
For j = 0 To Me.DataGridView1.Columns.Count - 1
xlWorkSheet.Cells(i + 2, j + 1) = Me.DataGridView1(j, i).Value.ToString().Trim

Is it possible to export an entire row to excel, instead of having to do it one cell at a time? I'm just looking for ways to make the process faster.

View 15 RepliesI've created a class library and built a dll (release build). I've then referenced the DLL in another project (I've tried several). I can see the namespace and classes in Object Browser and I can declare instances of the classes but I cannot use or see any of the methods or properties! there is no IntelliSense whatsoever and calling the methods manualy results in a 'Declaration expected' error.
Within the class library solution I have a unit test project referencing the class library project which works all works fine (and all the tests pass).
Can anyone provide any pointers to what might be going wrong here? I've built plenty of dlls in the past and have had no trouble referencing them at all.[code]...
There is a site that I go to that has a website chat thats located at the bottom of every page. It allows you to talk to specific people while you're online and they're online.
Sometimes when I get into a good conversation I don't want to end it. I still have other things to do though.I wanted to make a small window that I can just drag around that will allow me to chat with people easier.
I've set up pretty much everything in this program except the actual retrieving of the information from the site and the replying to the chat. I know I could do this (I've done similar things in the past) by putting an invisible webbrowser object off to the side and just run my stuff through there. But I think thats kind of sloppy.
I've read in some of my classes and books and have learned how to make simple web requests that return the results. In its case, I had to return definitions from google. I tried this on a recent project but found that it didn't the permission to access any kind of secured account whether it was logged in or not because it was "unsafe".
Does anybody know how to access a page thats been logged into through IE but without needing the sloppy methods I mentioned earlier?
I have a class which has various methods that I need to make public to only 1 other class. Is this possible? I don't want to make them public for everybody, just that 1 class.
View 1 RepliesI have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.
Option Strict On
Public Class Form1
Dim sw As Stopwatch

The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.
I was just wondering if a computer would add two numbers together (positive) faster that comparing two numbers.
I was thinking that it would be comparison (best case) due to the fact that the 0th bits could be different right off the bat. Where as when adding, moving from bit 0 to N is mandatory for addition.
But then again a computer may add/compare differently than I am imagining.
I have a simple multithread application that stores updated data from a list of websites. After each thread gathers data, it then store the data into the same text file. I am now thinking of having each thread store the data directly into a arrayList, and after a certain amount of time past, store from the arrayList to the text file. Which situation would enable the application to complete its task faster?
View 1 RepliesI'm new to VB so was wondering if someone could guide me in the right direction (if what I�m proposing is possible). I�ve got a website that has a MySQL database as part of the package. Is it possible to have a vb app that can connect to this database, perform a select query and send the result back to the client? My vb client app would be at home and the database would be on the net. I tried google and it came back with all sorts of random nonsense. Problem is I�m not sure exactly what I should be searching for. Could someone steer me in the right direction?

I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).

View 3 RepliesI 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?
