I have been using VB6 forever, but I need to to create new app versions for Vista/7, and beyond. My employer bought Visual Studio 2005 Pro a few years back, but i have never opened it.What would be the best upgrade step for me from VB6? Is 2005 adequate, or 2008, or 2010?
We primarily create apps for building and hardware controls, monitoring, logging, and communications. Will be using MySQL in the cloud with apps too.
I have just upgraded to 2010 and i am having a problem with my first conversion. Part of the applications form load which as been converted from 2008 to 2010 is to check if a string in my settings is empty or not (databasepath), if its empty then browse for the file. If the user prsses cancel then it should close the application. This was working fine on 2008 but now it gets to Me.Close, goes to formclosing then comes back to where it was in form load and carrys on until it throws an error further down the code where it shouldnt really get to. Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.

View 2 RepliesI know that VS 2003, 2005 and 2008 had the VB6 to VB.NET Upgrade Wizard. Now, on a email list I'm on a said that he cannot open a .vbp file to use the upgrade wizard in VB 2010. Is there no Upgrade Wizard in VB 2010?

View 1 RepliesScenario: I have about 14000 word documents that need to be converted from "Microsoft Word 97 - 2003 Document" to "Microsoft Word Document". In other words upgraded to 2010 format (.docx).
Question: Is there an easy way to do this using API's or something? Note: I've only been able to find a microsoft program that converts the documents to .docx but they still open in compatability mode. It would be nice if they could just be converted to the new format. Same functionality you get when you open an old document and it gives you the option to convert it.[URL]..EDIT2: This is my current function for converting the documents
[Code]...
Also it opens word after about 2 or 3 conversions and starts flashing but keeps converting.EDIT3: Tweaked to code above a little bit and it runs cleaner. Takes 1min10sec to convert 8 files though. Considering I have 14000 I need to convert this method will take a reasonably long time.
EDIT4: Changed the code up again. Uses a threadpool now. Seems to run a bit faster. Still need to run on a better computer to convert all the documents. Or do them slowly by folder. Can anyone think of any other way to optimize this?

View 3 RepliesWe are getting ready to convert to Exchange 2010. Currently we're using VB code to add new users to AD and create mailbox for them with specific settings. I've been trying to figure out - what do I need to change in my code in order for the code to work in Exchange 2010 environment. I've seen some references about using Powershell in a remote environment and guessing that AddPSSnapIn will no longer work. Not sure about hardcoding username and password for remote access. Is there any way to avoid it? Whose u/p should it be anyway? AD user who runs the code? Below I'm posting the code that we using in Exchange 2007. Please let me know what I need to change?

In VB6 I have drawn lines on a picturebox and if I display another form the lines remain (I haven't drawn them in the paint event).In vb2008 doing the same the display is erased when another form is displayed.How can I reproduce the vb6 functionality in vb2008?
View 1 RepliesI have an old VB6 project converted into VB2008 express. It contains a datagrid control called AxMSDataGridLib.AxDataGrid. This is probably legacy control from previous VB versions, am I right?
The application reads data to this grid using ADO and it works most of the time. It is supposed to be read only but I cannot parametrize it correctly and sometimes when I exit the application I get an exception. Now, I seriously lack skills of this IDE and .net framework since I don't know how to get more info about the exception. The exception is just a messagebox saying something like "Key column invalid or not sufficient. Update changed too many columns". This exception comes from this datagrid.
Now, since there's a high probability that this is an old control and I cannot get the exception handled, I was thinking to upgrade it to .net DataGridView. Does anyone know if upgrading this old AxDataGrid to .net DataGridView is possible and how to do it?
I am abit afraid to just delete the old control and replace it with new since the application works and I am not attached to any source control (for reverting changes). Maybe it's possible to make a copy of this project with another name and safely play with it?

View 4 RepliesSay I have a Framework 4.0 project that is referencing a class library targeting 3.5. The project will simply not build. It won't give me any valid error message it will just act as though the reference does not exist.
Projects that were working like this in Visual Studio 2008 are no longer working in 2010. Took me forever to figure out what there error is. If I remove the project reference and add it back the intellisense lights up and you can tell a variable referenced in the class library is found. But as soon as you build the project everything is lost. My using statements get underlined, references to the variable all turn grey and project fails to build saying the class cannot be found. Once I make the class library 4.0 as well everything builds. I get the same issue between 4.0 client profile and 4.0 as well.
I have a Visual Basic 6 program that I would like to update to Visual Basic .NET I am running Windows 7 Professional and have downloaded and installed Microsoft Visual Basic 2008 Express Edition. The problem I have encountered is that when I open my VB6 project file (.vbp) the Upgrade Wizard does not open. Instead, a list of references, objects and forms from my project appear. Is there any other way to run the wizard? Or am I missing something?

View 2 RepliesI need to get a path from a resource file...
im planning to do a midi player; I've tried it via the included .NET and DirectX component, both needs a path to the audio file (String)....
how do I get a path from a resource file?
ps.: there's also a way to play via a stream-link/stream-player, where
my.resource.<filename> is enough, as this declares the directstream.... but I really need to get a path.
I guess this one is pretty basic, yet i have not been able to figure out.So here's the deal, my application uses an external exe to generate some txt files that the application needs for a use case. Since hard coding the path of such exe would be hideously wrong in so many aspects i would like to include a little configuration option for the user, so he can specify the path of the external exe for the application to be used.I also would like to have something like that for the path of the Database I'm actually using.
