.net Express 10 Speed In New Project Versus Old Upgraded Project?
Feb 24, 2012
If I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.
Public Class Form2
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim l, h, p As Integer

I upgraded my project to VB 2008 and in the designing window, everything looks new and updated. When I run the program, however, it appears to look the same old way it looked in the old VB I upgraded it from. Is there something I can do to make it appear the new way during run time?

Why upgrading my project from 05 to 08 would stop it from working on any new computer. It will install fine on my computer and users that currently have it installed. I assume it's the crystal prereq issues. It always fails with crystal errors now on install. The prereq's are checked in the properties.

I have a VB.NET solution, just upgraded from 3.5 to 4.0. One of the classes has a private field:
Private _Projection As ICalculatedPath.At runtime, any time the class containing that field accesses that field, I get a FieldAccessException. The first time that field happens to get accessed is a null check in a method, and one of the things I randomly tried is changing the above line to:
Private _Projection As ICalculatedPath = Nothing.When I do this, I get the FieldAccessException on that line saying that the class's .ctor() cannot access that field. I've also tried making the field protected and public, clean/rebuild solution, restarting VS, targeting x86 and .NET 4.0 specifically on every project in the solution, and other non-sensical measures to get rid of this Exception but to no avail. This code worked fine before the upgrade, of course.

Regarding a console application and VB forum program - In searching XML parsing examples I find several using Console.Write and Console.Write - To show my inexperience I (out of habit going through a couple preliminary examples) I created a new VB project with a blank form - I then copied and pasted the XML example using the console commands Errors - I just found the "create console application"What is the difference between a console application and the project using a blank form? Can the console commands like Console.Write work with a VB form project?If so (#2)What is the advantage in creating a console application - why not just start with a blank form and go?

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

I have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.

I originally created a project in Visual Studio Professional 2010. I then saved it and was hoping to be able to open it in the Express (2010) version. When I try to open the project it directs me to a page: [URL]
Do I have to go into the Pro version and export it in a specific way?
Note: By export it I mean just copying the directory (and sub directories), the solution was in.

I was a COBOL programmer agout 15 years ago and I am now just getting into Visual Basic. The owner of a local business has asked me to write a program to perform what I think is a simple task. In the past the business would process payroll checks and print them in-house. Now they are using direct deposit. Checks are no longer printed. The check stub though is printed. This stub is then carried to each of 10 locations across West Tennessee and distributed to the employees.
This is my task: capture the stubs to a file (PDF, XPS) and email it to each employee. This way the employee will recieve the stub on the same day the deposit is made. I can capture the output file (the stubs) and save it as a PDF file or a XPS file. I can send an email from within a program. What I don't know how to do is open the PDF or XPS file, read the email address and insert the page into the email body.

I make a lot of programs that require an internet connection to download things from the web.At the very beginning, I used WebClient, as I didn't know Socket & how it worked.But now, I use Socket all the time, altough it's more lines of code. It seems to work faster then WebClient.I am interested if this is really true & why WebClient is slower (so is HttpWebRequest) then just a Socket.I've setup 2 threads which starts on the click of a button (WebClient thread starts first), the Socket beats the WebClient by just some milliseconds, but still.Each way has it's advantages & disadvantages, e.g.: if you use Socket, you need to write the header yourself & parse the response header.My question is, which one do you prefer & why ?Do you know why WebClient & HttpWebRequest are slower then Socket, as I assume, WebClient & HttpWebRequest both use tcp to download the things.

I have written a program in VB.NET 2008 Express that references a .NET managed dll. I simply added a reference to the dll to the project. I then 'Imports' the dll at the beginning of the program and then can use it. Everything works fine when I am running the program in debug mode (and it uses the dll as intended), but as soon as I go to build the project I get an errors that it "Could not reslove this reference" and "Namespace of type specifier in the Imports 'ModbusTCP' doesn't contain any public member or cannot be found." The dll is located in a different location on my hard drive to the project location, but this was referenced when I 'added reference'.

i have a project and i used NSIS to create a Setup file. I am able to install it to my system but some parts of the program do not work (and they work when i run my project in VB). For example i have a Back Up option that creates a back up but this does not work when i run the application via the installation file. Probably it has something to do with the directories?
If System.IO.Directory.Exists(CurDirectory + "Backup Folder") = False Then
System.IO.Directory.CreateDirectory(CurDirectory + "Backup Folder")
End If
how can i make it work from the installation file? Do i need to copy something somewhere?

I've got an old legacy application for communicating via serial port to an embedded controller communications bus. that someone else developed.The application is written in VB6, and is structured as two projects - a DLL to handle the connection and communications logic, with an application GUI project.I was hoping to be able to write a new application GUI (in C++ ideally) to use the existing DLL as-is, but I'm having lots of problems working out how to import it.So I'm wondering, is it even going to be possible to use this old DLL into a C++ project as is? or is it possible to import into a C# project? or a VB.NET project? (would prefer not to use VB, but can if I have to)Where I am now: I have the existing compiled executable and DLL, and these run on my system.I also have the project files, and they're all readable in notepad++ but I don't have VB6, and importing the project into visual studio VB.NET 2008 express isn't at all straightforward. Especially not without a working example to dig through and play with first (DLL project may be importable, but has 50+ things indicated as needing changing in the upgrade report. It also seems to be ignoring three .cls files that look very important to my not particularly VB6-savvy eyes... The application project has a message in the upgrade report about something "missing a design time license" and the only project files that actually seem to come into the project explorer for imported project is the project file itself, and the assembly info file.)
Most examples of how to import a DLL into VS C++ assume you have a solution with the DLL project all compiling nicely alongside your project that will use it. Or at least a .DLL and .lib and .h file... I spoke with the original developer of the code (in another city, we don't work directly) and got a .lib to match my .dll, but still have no .h file.I'm usually fine to bash through something new, but without a baseline working example of the project even in VB6 that I can get my understanding from, it makes this very hard. Also a lack of similar questions anywher google can find them on the net makes me wonder if this is something i should be even attempting.I'm working on getting a non-express copy of visual studio if that will make any difference (express worked fine for everything up until now so I never needed anything more) but that will take a number of weeks, most likely.

I'm trying to add a folder and some files within it to a Visual Studio 2010 Express VB.NET project. I have read the answers to questions on this subject here and here. They both say "select folder, right click, and then select Add To Project". But when I right-click in this way, no "Add to Project" option appears. Does anyone know why this is so, and what I can do about it, or alternatively another way of adding a folder to a project?

I have been learning about working with databases and VB. I have coded the connection string for a MS Access database to my VB project but i cannot establish a connection with my sql mdf database.
The code i used to connect to MS Access is:
<Dim dt As New DataTable()/>
<Dim match As String = ""/>
< Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
[Code]....
What is the connection code in order to manipulate data from the mdf file. Is it similar to the above code.
