In CRUD application development we have to face the issues with concurencies in Ids such as Generate and display UNique EmployeeIDs on forms. Currently i'm writting .DLL file that has a class that will handle concurrencies.
But i'm puzziled with the Question, is this concurrency handle is part of the software developer or Database developer?

I'm a C# programmer who needs to pick up some VB. The syntax differences are easy enough to figure out, but there are other things I'll need more of a tutorial on. For example, VB's "strict" mode in Visual Studio is something essential to me, but something I wouldn't have learned just by comparing language syntax. Any recommendations on how to pick up VB quickly, yet thoroughly? I can't stand to work through a 1000 page book introducing VB to novices.
View 10 RepliesI updated a VB.NET application from Visual Studio 2008 to Visual Studio 2010 and made a few changes to it. Now it works fine on my development workstation but when the user tries to run it, it fails. The error detail is below. I've searched for System.InvalidOperationException and found several suggestions but none of them have helped. There isn't any static initialization code in the application. I changed the compilation to x86 instead of AnyCpu. None of these has helped. The project is compiled for .NET 3.5 and that hasn't changed. Both environments are Windows 7 64-bit.
Does anyone have a suggestion as to how I might determine what is causing this?

I have been trying to download the Visual Basic and it took me 3 days now to download because my network is not always good, so when the net is off, I have to start it over and over again.

View 3 RepliesI went for an interview last week, and the interviewer asked me a question that i failed to answer.
He asked me, how did i store the password in the database. Then i answered that i would encrypt it then store it in database.
Then he said after encryption, developer or admin still able to view the encrypted password. But he didn't want developer or admin to be able to view the encrypted password.
I thought of cookies, but if user clear their cookies file, everything will be gone.
I've been an ASP.NET VB.NET Web Developer for the past 4 years, but its been mainly self-taught so I think theres a fair few basics I have probably not learnt along the way.I'm interested in switching to C#, and was wondering what book would be best to buy to learn this.Is Jon Skeet's 'C# in depth' book a good place to start learning, or would this be too difficult for me to start with?

View 11 RepliesI am doing a project on the CRM application which can sending or receiving of emails and sms. Most of the CRM application that has been build is using the web form which mean the application of the CRM is build as website. But the problem is that I am doing it in the windows application. The CRM application that I am doing is the the admin can send/receive emails and sms. It is some sort like microsoft outlook. but the difference is that in microsoft outlook it can only send emails. When i search the internet for the gateway, there is no free gateway. Is there any examples for sending or receiving of sms and emails. My group partner is doing on the emails which he uses the SMTP server.
View 1 RepliesI am doing a project of CRM application which does sending and receiving sms/email. I am doing this using the visual studios 2005 ans SQL Server Database to store the send or received sms/email. I have search on sms in the internet but the problem is that it is using C# as I am using the vb.net language. Even though some of the research that i came across is in vb.net but the application did not work.
In my research, the sending and receiving of sms application uses sms gateway, AT command. But I am not sure which one to use becoz I am doing this application for my project. Hope for any recommendation on which one to use either the sms gateway or AT command or any other device. My lecturer said that my project is most likely like the M2U Mozat. Not only that I am doing the sms but also the email. The email part is done by my partner but the problem is that he creates the email using the SMTP server. How can using a SMTP server to create sms? It is because the part that I am doing which is the sms and the email to combine together.

Google search does not help. What is really funny about this is that from my search I see there are multiple solutions for this problem that have worked for different people, none of which apply to my situation.Why do I get the feeling that God does not want me to learn VB programming? (Grin)
I want to put a button on my Visual Web developer 2005 Express edition page (one single web page) that will close the internet web browser (IE 7 being used), when my users click on the closed button. I need to write visual basic code to closer the browser but haven't found an example that explains how to do this in code. Can someone give me an exmaple of how to accomplish this in Visual Basic Code.Paul Mayer
View 1 RepliesI have completed a small VB console app to read data from a BT card scanner. From within the VS2010 developer the app runs as desired, capturing the data and displaying it on screen with console.writeline().When I compile and execute the code either from the debug bin version or the release bin version, the app only captures the first few bytes then closes. All the code is within the Module1 Sub Main. Is there a compile setting or other property that I need to adjust?
View 11 RepliesMy home page contains three Dropdownlist controls, the lists are populated from my database i created ie. (From three tables)- Courses, Grades and Schools.
I want a situation whereby a user clicks on any of the Courses, or the Grades, or any of the Schools from my dropdownlist controls, and selects the search button, the names of the students that took the course, their grades in that course, and their schools should appear in a table form. if its a Grade that is selected, the names of the students with the grade, their courses and their schools should also appear in a table form. And likewise the School.
I have class containing 10 properties. It has constructor which accepts one string parameter say "Param1". This is actually a liabrary which will be exposed to the developer.
Now when developer writes a code for creating instance of this class and pass the param1, then depending on the value of param1 developer should be able to see limited properties.
If Param1 has value1 then developer should be able to see 4 properties.
if Param1 has value2 then developer should be able to see another 3 properties etc.

View 2 RepliesI am wondering how I would get the information on what errors get processed by the application.unhandledexception. I already handle the event and gather the information, but I am unsure how or what the best way to get that information to me (the developer).
So far I have vdialog that asks the user if he/she wants to send the error to me, kind of like when an error occurs in Windows XP and a dialog asks the user if they would like to send information about the error to microsoft. I am unsure what to do when the user clicks "Send".
I have thought about emailing to me, but I don't really want to put my email address as the from, because I might change it or its password in the future, thus breaking its usability.
I cannot yet do an anonymous FTP upload, because my website only allows one FTP user, and that is used only to update the website.
I also have thought about using the user's default email program, but that will not work in most cases of people who rely on web mail.
I've been using c# for the past year and I enjoy the power you get with Fluent NHibernate. One question that I get from friends is "nice but how can vb.net programmers use this?"So for example- the below is a c# mapping class. How would someone do this with vb.net?
public class PostMap : ClassMap<post>
{
public PostMap()
{
