View 3 RepliesI am working with MS Visual Basic 2008 Express Edition and MS Access 2007. I have managed to populate a temporary table with data from a text file containing eight fields. I have applied the namespace System.Data.OleDb What I want to do now is: 1) to order the data by a specific field (let's say Fld4); 2) delete duplicate records; 3) append the sorted data to a main table; 4) write the data from the temporary table to a new text file and save to a folder; 5) clear the contents of the temporary table

View 4 RepliesThe Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?
I have recently taken a liking to programming, and have programmed a few games in C#,my friend has asked me to program an application for him to use in his shop. But I have no idea of what language is best suitable?
View 8 RepliesFor a few years I developed websites in PHP, but couldn't get a job doing this nearly two years ago. I spent a year teaching (and if your thinking of teaching, my advice is don't! In the UK anyway), but kept handing my CV out to different web development companies. One of these offered me a job, but the downside (or upside, depending on your views) that they only developed websites in ASP.NET. I made the decision for a career change and accepted the job.
In ASP.NET, you can develop in either C# or VB.NET. The guys I work with are using VB.NET, and I have to say I'm struggling with it. I can understand the basics but it just seems weird, especially as I've come from PHP. C# on the other hand, looks similar to PHP. I'm contemplating learning C# instead of VB, but I'd like to know what other peoples opinions are about doing this?

View 5 RepliesIam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.
The only programming language I know is C++, and I would like to learn some others, specifically Visual Basic. So — what are some good beginners tutorials for VB, and what others languages would you suggest are good ideas to learn?

I have some very rusty C++ and lots of C experience, but have done little OO design or coding.I've started learning C++.NET as that seemed to be the best starting point.I've hit restrictions in Microsoft's provision with multiple inheritance and extensions, neither work in C++.Would I be better off starting again with C#, or am I better off using a mixed language approach. eg. extensions in C#, rest in C++?I'm still struggling with this->method or that.property and theother::staticthingy or whatever, and this probably is not an issue in C#. You'll see what I mean as that probably isn't the right way to desribe the difference between '->' '.' and '::'I'm getting to achieve what I want, but it's taking me 10 times longer than I think it should.
View 7 RepliesI realize that VB.NET and ASP.NET are the successors of their seemingly obsolete classic counterparts, but I have noticed that some job descriptions still list VB6 and classic ASP as requirements. This may be because they want people who can convert code from classic to .NET, but I'm not really sure.

View 3 RepliesI've been programming in C/C++ for several years and want to learn enough Visual Basic to create GUI front ends for some of my C programs & also so I know that C functions I have written can be called by VB programs that others write. I expect that the C programs would have to be turned into DLLs for this to work.
I have created some C DLLs & created other C programs that sucessfully call the functions in the DLLs. BTW I did this with Visual Studio 2010, would there be any advantages to using other versions?Can anyone recommend a book or a website to quickly get me up to speed on VB while allowing me to skip over the parts that are intended for people who are new to programming?
Many of my programs call functions from the Windows API such as CreateFile. IINM these functions can be called from VB, but it is done differently than in Visual C++, eg: in C++ Create file returns a HANDLE variable, but the HANDLE variable type doesn't exist in Visual Basic. So I'll need to learn enough about how Visual Basic uses the Windows API to pass the file HANDLE from the C functions to the VB calling program & back.

View 7 RepliesIn my applications I use objects and classes, but when reading SO topics, I have the idea I don't use real OOP principles. For example, I never use inheritance or interfaces. Therefore, I am trying to learn proper OOP (in VB.NET), but I find some concepts quite hard to understand (even after reading a lot about the subjects on SO).So I'm trying to find a book or resource with good practical real-world examples. For instance, I kind of understand examples like using an interface for both Dog and Cat classes when using a EatFood method, but I find it hard to relate it to real-world cases.Ideally these books or resources should cover explanations about:
- when and why to use inheritance or interfaces or abstract classes
- when and why to use private, public, protected, virtual etc.
- best practices in dependency injection /inversion of control
- when to use aspect oriented programming
- using of constructors
- solid principles
- singletons
- encapsulation
Perhaps it's a mix of all kinds of concepts, but I think these are all related to OOP, please correct me if I'm wrong.I would prefer a book/resource with VB.NET examples, but this might be difficult?
