I work for a medical devices company and as such, we need to keep a very strict and regulated development environment.Since we are using MS Visual Studio as our main SW development tool we need it to comply with FDA regulations.So, is Visual Studio (and its compiler) FDA approved?

View 2 RepliesI'm from an AS/400 (iSeries) background and have no idea about how a team of programmers work within the .Net environment. Lets say a company purchases a new button control. Now, in that company they'll have 5 or 10 developers working with that new control. Its my understanding that even if the control is in the GAC, it must still be copied locally to work on at design-time. My question is, what is locally? Does each developer have a copy on their own PC or is it held centrally on a server?
View 3 RepliesI have inherited a large VB.NET solution that was created in VS 2003. I am trying to update it to VS 2008 to maintain it. I no longer have access to an install of VS 2003.
The solution contains 15 projects that are console applications and 1 that is a Website application. The website application refers to some assemblies in the other console projects.
When I try to open the solution in VS 2008 all the console applications open but as it tried to open the Web application (or website? -- not sure) I see the dialog "Trying to open http://dmedibiz/dotcom.vbproj". It is unsuccessful in doing so. I don't have a website named http://dmedibiz on my development machine.
I tried changing the name of the website in DotCom.vbproj.webinfo, but that does not have any effect in VS 2008. When I go so far as to change the Hosts file so that the local machine resolves "dmedibiz" to the proper folder on my local machine, I keep getting prompted for a login and cannot access the folder even using the administrator login. I have tried adjusting the security on the Folder and in IIS Manager and even in the Frontpage Extensions, but nothing works.
So, what can I do to open this web project along with the other projects whose classes it references? Is there a way to change the website reference in the upgraded application? I actually do not want Frontpage Extensions in the site, but there was some reference to that also in the erro messages about installing them to "fix" the problem.
Here is the error I am receiving...
Unable to open the Web site '[URL]. Could not find a Web server at 'http://dmedibiz'. check to make sure that the Web server name is valid ...'
Can anyone tell me how to change the website location reference? Or must I remove the Web project from the solution and create a new Website and then copy in the files that need to be worked on?
Why would database drivers work in the development environment of VB.Net and not once the project is built and installed on the same pc? I've tried the MS ODBC Oracle driver. I've tried various ODBC datasources. All work when I am in the development environment but none once I build and install. No matter whether the configuration is Debug or Release. This is the only project having this problem. I have other apps (VB.Net) that access the same database (Oracle 9.2) with no problem.The environment variables are the same during both types of runs. The error messages vary depending upon the driver being used.
View 1 RepliesIn VS2005, I noticed that when you go from the code window to the form window, the form immediately appears, but then redraws again, and takes about 4-5 seconds to come back. Is there any way around this annoyance? Has it been fixed in VS2008? In general, has anyone noticed any speed improvements in the development environment between VS2005 and VS2008?
View 9 RepliesWell I've finally decided to upgrade some of my vb6 applications. Anyway I have two forms that are very similar one is customers one is vehicles. One of them is working on form load and one of them isn't. The one that isn't working I've traced the point it stops down to where there is a green line left of the code on the left bar of the development environment. This green line doesn't exist on the form that works. What the green line in this photo means? [URL].
Bigger Picture [URL]. I found a page that says the green simply means the code was saved but it's only on the form that stops working right after the execution of the sql statement. For some reason while stepping through the code it returns to the show command that was called to originally open the form right before the form opens but it skips everything with the green line next to it. I went and disabled tracking and it went away.
I have just started using VB.net, and am currently using VB2010 Express. Previously in VB6, I used the MSCOMM control for communicating via the serial port.
1) What is the minimum development environment required for RS232 communication? I assume VB2010 Express will not be sufficient.
2) What control or class should I use?
In case you are interested and have not spotted this.>>

I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.

I have VB6 Dll which I am referencing in vb.net ,I am calling the following function in it. It working fine in developemnt environment but not in deployement environment.
Error Method not found: 'Boolean MyUtils._MyUtils.LoadMyObjectRecords(ADODB.Stream ByRef, System.Array ByRef)'.
I have to take over a project written in vb.net, which contains more than 400k lines of code written in option strict off mode. I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.

I really prefer to keep Option Strict On. the proper way to do this?
I have inherited a VB.NET application that I need to compile so I can run dorkumentation on it. I first received "Option Strict On disallows implicit conversion from x to y" errors, so I turned off the Option Strict option in the Project file.
So why do I still fail with the same error message?

Dim inp As mshtml.HTMLInputElement

Looks to me that childnodes object has a more specific type. But what? Not ihtmlcollection. The type support some item interface.
Title says it all really, should I have it off unless I'm having an error, or simply have it on all the time?
View 10 Replieswhat do you thinkg about comment below? original article url is also suggested to read.I didnt get why my code will be faster if i use it on. anyone has good knowledge about it?
Although Visual Basic .NET allows you to perform implicit type conversions and late binding, you should avoid these practices. Implicit type conversions and late binding may lead to severe performance problems, runtime errors, code that is difficult to read and maintain,and sub-standard programming practices.Many VB.NET professional programmers believe that leaving OPTION STRICT OFF by default was perhaps Microsoft's worst decision in the VB.NET implementation. Use OPTION STRICT ON.

View 4 RepliesWe have a couple of applications at work that need a reference to the license server set in the User Variables under the Enviroment Variables on the windows xp client machines(system properties, Advanced, Enviroment Variables). The problem is that both applications needs a reference to the same variable name and you can't have two with the same name. What i intend to do is to create a simple windows application with a button for each application that deletes the variable item present, adds a new variable item with the value needed for that application to be able to run and then run the application itself. This is just a temporary fix until we get a more permanent solution. The 'GetEnvironmentVariable' class in vb is not able to add or delete a item, maybe the WIN32 API could do the job.
View 2 RepliesI was trying to learn how to do openGL within a VB .NET environment and it seems that the Tao framework or OpenTK is recommended with OpenTK having a higher recommendation so that is what I chose to try using. Since I am brand new to this, I am trying to just draw a simple box, triangle, or anything really so that I can understand it all before making more complex things. I have been unsuccessful at this so far so I will list in order what I have done so far and hopefully someone here can help me correct it or provide a new example just so I can draw a simple shape.
1) I installed OpenTK using opentk-2010-10-06.exe
2) In a new project I added the references to OpenTK.dll and OpenTK.Compatibility.dll
3) I added the control (opentk.glcontrol.dll)
4) I added the actual control to my form.Using some examples online I added the rest:
5) I wrote my references in:
Imports OpenTK
Imports OpenTK.GLControl
Imports OpenTK.Platform

View 2 RepliesI have an old programme that was written with 'option strict off' I have been steadily working through it mainly sorting out casting issues but have come up against some that I dont understand.for instance I have a checkbox called tickbox
dim Tickbox as new checkbox
later in the code
dim blah as boolean = Me.Tickbox.CheckState
but option strict insists i cast it as a boolean
dim blah as boolean = CBool(Me.Tickbox.CheckState)
surely the checkbox.checkstate is Booleean?
Do you use 'strict off' option, 'explicit off'? Or may be 'strict custom' and some other options like 'Implicit type. Object assumed', 'Late binding', 'Implicit conversion'?
