View 7 RepliesI have a few small apps developed with VB2005 and Crystal Reports(that comes with VB2005) and installed at my clients. If I convert them to VB2010 and set the app to work with .Net Framework 2.0 like my VB2005 apps did, will I have to do any installation process at the clients or can I just copy to new VB2010 app to clients machine?
I ask this because when they want minor changes, I usually just install the updated exe over the internet.
My pc is a Vista SP1 + VS2008 I try to import a csv file into an existing access database with the following code but I have the message that the database is only in read access and I can't update it with the csv file.I tested the code on an other pc with XP and VS2005 and it works.

I was studying visual basic 2008 and had reached almost 60% of it when I was told that my course curriculum included visual basic 2005. I will now have to reinstall visual basic 2005(.net framework 2) instead of visual basic 2008(3.5 .net framework). I was wondering- will it be completely different vb2005 and vb2008? I really wanted to stick to vb2008, I was getting the hang of it. Also, I was wondering, can I run my application vb2008 in .net framework? Is there any way around? Also, I used advanced installer to build a setup file for my application? Now the question is will the other computer(the one which will install from the set up) need .net framework of 3.5(since I built apps in vb2008)?

I created a windows form in VB 2010 and I am trying to view it in 2008, but I get the error message "The selected file is a solution file, but was created by a newer version of this application and cannot be opened".
Is there anyway I can re-save the 2010 project(similar to Microsoft word) in order to be able to open in older version?

View 6 RepliesDoes anyone have a list of OleDBTypes and how they match up with MS Access and SQL Server Data types. I would like this to be able to better write code for my parameter collections. Plus when looking at all the options availible with intellisense when programming in vb2008 v.s.

I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
Is there any advantage to using the VB2010 express version versus the VB2008 express version? Can they be installed side by side or will VB2010 express replace VB2008? I have no issues with the 2008 version, so I don't know if installing the 2010 version would be of any advantage.

My question is one of a fairly simple nature, how do you make a thread safe singleton constructor with Visual Basic?
I tried a similar pattern to the one above, only to find that I had a lot of difficulty declaring the static variable instance as a null, this in turn would ruin my public Instance property, as I would have no way of telling if the class had been instantiated or not...
Anyhow, even a simple explanation as to the correct way of doing this would be nice, I'm sure I can fill in a lot of the grey areas, I just need more information than what I'm finding in MSDN, it seems Singletons are only really described in detail for the other languages...

View 10 RepliesI have made a windows application (running parfectly on my system). Now i want to run it on another computer.
Here's what i tried: I noticed that an exe file of the application is created inside the Debug folder after the application is deployed. So i thought that copying and pasting the .exe on any other system should work fine but trying to run the exe on that system gave an error and it would not run.
P.S. This application did not have a database. Also, i have made another application which interacts with an access database. How will i be able to run that on another system?
We're building an application using VB.net and WPF. Obviously we've found that there are huge differences between the syntax in the two, and we have a few problems trying to do things in Form apps in WPF.If possible, could you pass us some resources on things like switching between WPF windows, we'd use Show() and Close() in WinForms, and referencing variables from other forms, i.e. otherForm.StrVariable references StrVariable from otherForm.

First off I am so VB.NET green it's pitiful. I am a AutoCAD Manager and I need to start migrating my VBA code to VB.NET. That being said, I am very familar with VBA,and some asp.net, and trying to use that knowledge to self-train in .net. The trouble I'm having is communicating between the various objects in .net. That being said, here is the first of many issues.
Currently, I am working on a file processing program that checks a user selected folder for .dwg files. I'm attempting to use FolderBrowserDialog activated using a "Browse" button , and can't seem to, first get the dialog to show a folder structure from the FolderBrowserDialog object and second, get the initial dialog code to take the "SelectedPath" method. Error "SelectedPath is not a member of "folderbrowser"
I can post code, but I'm not sure what snippet would be the most informative of my problem.
I currently had a .Net Remoting Application running on Framework 2 under IIS. I have to upgrade it to Framework 4 in order to use some new components. I have been able to set everything up and running smootly on Framework 2, but as soon as I change to Framework 4, I get the following exception when I try to call one of the function of my remote object.
The input stream is not a valid binary format. The starting contents (in bytes) are: 53-79-73-74-65-6D-2E-52-75-6E-74-69-6D-65-2E-52-65
This bug is not the real bug, it is caused by the fact that the remote object is throwing an exception, and IIS wrap the exception in XML, which throws the BinaryFormatter off.See this for more info on the bug.
This is very unfortunate because I cannot see what is causing the exception, and having never used any Remoting before, I do not have much ideas as to where to start debugging. It seems the Exception is thrown before even stepping in the code because I do a fair amount of logging and none of it seems to be triggering.Basically, I'm looking for some clues or pointer from people that encountered similar problems:
What could be causing the exception when no code has changed besides Compiling from .Net 2 to .Net 4?How can I get the full Exception message that is returned?

I come to programming from a school of functionality rather than theory- writing programs to meet a goal or solve a problem.I haven't had any education in computer science so many aspects of the Visual Studio world are alien to me.Just for fun I wrote a very small program to help with a computer game.It's called the All Lucky Sevens calculator for Final Fantasy 7.If you haven't played the game it won't make much sense to you so I'll eschew the logic of why I wrote it, focusing on what it does.
Basically it performs a series of percentage calculations on a number input by the user, trying to convert the original number into one that ends in 77. So 6104 reduced by 7% is 5677 The question is, how difficult is it to convert VB.NET code to work as a web-based app. I thought .NET was designed to make it easier to do this? Is it relatively simple to convert VB.NET code into something that can be run from a website? If not, the solution is to rewrite it in a different language like Java or Flash.The actual programming of it would not be difficult, but I do not speak those languages and it would require rewriting all the nested loops and ifs.Forcing VB to round down a decimal to an integer was difficult enough, I daren't think how hard it is in a language I've never used before.
We have a small visual basic 6.0 application with an Access DB that we would like to migrate to modern code and architecture. I am not technical, but I am believe this would be something like a .net framework with a SQL Server DB.What I am wondering about, is there any way to covert this code to a modern language/architecture? If so, what is the easist modern language to migrate to?

I need to convert my winform VB.NET application to an ASP.NET application.My current application has 4 forms, it reads a remote XML file, and uses a datagrid to collect user input and to create a report.It is a very simple application, and I would like to know where to start to convert it to ASP.NET.
View 3 RepliesI'm currently trying to convince management of the need to port one of our applications to .NET. The application has grown to be a bit of a monster in Access (backend in SQL), with 700 linked tables, 650 forms/subforms, 130 modules and 850 queries.
I pretty much know all the major benefits of doing this, but now need to look at how this can be achieved technically, so I can put a project plan together.So, my plan was to convert the queries into stored procedures and/or views on the backend and re-write the forms in WPF or WinForms.
Now, the code is where I come unstuck. Is it possible to packaged up the code behind and modules into dlls and consume them whilst it is slowly ported to VB/C#?
What we can't be left with is half an application in VB/C# and half in Access, it must 'appear' to all be one application, even half way through the migration.EDIT: Just some more info about what we do and why we're looking at moving away from Access.We are essentially an ISV and the Access application is our main product. This application has been developed over a period of 15 years, by many, many developers on an ad hoc basis. There is no documentation for this application.
We also have problems with getting branching in SCC to work properly, so we've currently got 4 or 5 code bases for the half a dozen clients we have. On top of that, all the testing we do is completely manual, which you can imagine is very labour intensive, and only scratches the surface of what really needs to be tested.We're currently looking to expand, and have a number of sales leads that are in the final stages. I'm worried that with these new sales, we're going to be swamped with support and testing, and that this application is going to become even more entangled an buggy.
I'll also add to this the fact that we're just about to enter the spec phase of a brand new product, which is almost certainly going to be built in .NET. If we were to rewrite the Access application in .NET, then the people we use for that can go straight on to this new development. If we were to stay in Access, then we'd have to get some new Access people in, whom would have to be retrained once we start the new development.
So essentially it has come down to two choices, major refactoring work in Access to try and 'organise' the code a bit better, and those of you who have suggested culling parts are most probably right; I'm sure there are parts that are no longer used. However, I fear that if we stay in Access we still won't be able to build in effective testing and we still won't have proper SCC branching, which will lead to support continuing to be a nightmare, and any future developments on this product makings things worse. Either way there is a lot of work that we're about to embark on, which is either going to be done in Acces, or .NET.
