I work for an FDA regulated company, and they are obviously very particular about keeping track of any software changes. If I build a Windows application and then later wish to make a change to that application, does Visual Studio provide a way to save the source code for the old version of the app and the new version in separate locations?

i have this code in saving a picture.
vb.net
empno = txtEmpNo.Text
Dim myFile As System.IO.FileInfo = New System.IO.FileInfo(imagelink)
'' Create a new stream to load this photo into
Dim myStream As FileStream = New FileStream(imagelink.ToString, FileMode.Open, FileAccess.Read)
'' Create a buffer to hold the stream of bytes
[Code]...
but when retrieving, i got an error on this part "Dim FinalImage As Bitmap = New Bitmap(myStream)". The error message goes like "System.ArgumentException: Parameter is not valid. at System.Drawing.Bitmap..ctor(Stream stream). maybe someone would like to help me, on where is the origin of this error.

I'm working on a project with a large multidimensional array
resrv(200,12,31,33) it keeps track of information on specific dates within a 200 year range.
What I'm looking to do is save the array to a file so that I can load it again when the program is started.
In VB 6 I used to be able to use a simple for next loop into an open file and load it the same way. It doesn't seem to work the same way with Fthe filestream class in VB.net

im having trouble with several radio buttons. I have got a EMPLOYEE form, that saves Employyes to a file. I have used 3 radio buttons to state which department they are in.
Employee X is in GRP1 ... etc.
I can save X to grp 1, and retreive this record. BUT another record Y in grp 2, it reverts back to group 1...
If you see what i mean.
Therefore: How would i save which Radio button is selected from the three?

I have a website that was written in VBSCRIPT that I am moving over to VB.NET. Until I have time to get to rewriting some pages/applications,I would like to update some of the code so they work a bit better.I am trying to grab a server variable on the VBSCRIPT page that contains our username from the enterprise login.I have 2 test pages here, one with language="VB" at the top and the other language="VBSCRIPT".
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Server Variables</title>[code].....
The VBSCRIPT page will list variables with no data when they have data on the VB page and in ALL_HTTP. Is there any way I can get VBSCRIPT to gather the correct info for all the server variables?
EDIT: These are the variables that vary between VB and VBS AUTH_USER, REMOTE_USER - logged in user on VBS, iis_anon on VB REMOTE_PORT - not listed in VBS
The following are listed in VBS, but have no data
HTTP_SERVER_PROTOCOL
HTTP_SM_TRANSACTIONID[code].....
Also there is a custom on I wish to get that is used for our enterprise authentication.

i have been in state of hectic for the last 2 days making lot of research and finally made this code worked it for me. My problem is that, how can i make this code retrieve the image from sql server database...use picturebox to load it in the vb.net program.
Dim myfilelocation
As
String =
"C:myPicturesmyimage.png"
[code]....
Is it also possible to change the location of image where its getting the image. i mean, i would like to tell other computers to get their images from anywhere as long as it brings images to my server.i mean, say that comp1 which is connected to my database server for storing and retreiving information, gets his image from his location then the application sends the image to my server...the application retreives the image from the server..as simple as that.

I have Memberships and Bookings tables in database containing an attribute cust_id which is primary key in Memberships and reference key in Bookings. When i am executing data reader I want it to read cust_id values from membership table but it is reading it from the bookings table. Also when i compare two cust_id values, 1 taken from a textbox and the other taken from database column, even though both are same but the comparison result is false. I have compared using string.equals(str1, str2) and have also compared the two directly using if statement but in both cases even if the string is same but result is otherwise. [Code]

I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")
request.Credentials = New NetworkCredential(username, password)
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails
Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)
messagebox.show (reader.ReadLine)
It gives me alot of information that I dont need, I know that I can use:
request.Method = WebRequestMethods.Ftp.ListDirectory
Which only retrieves the file name but when I try to change it, it gives me an error. Error number 550. ListDirectory so I can only get the file name?

Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.

So here is the error...
An error occurred while saving the Panel. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.ThrowHelper.ThrowArgumentOutOfRangeException() at System.Collections.Generic.List`1.get_Item(Int32 index) at PanelController.Save(Int32 ID, FormCollection FormValues)
During debugging, I checked the parameter it was adding to the save stored proc, and the ID it was adding was 0. Then, when it used this
oDal.Execute("Lending.uspPanelSave")
Item.PanelId = oDal.Parameters("@PanelId").Value
To retrieve the ID to return it, it set it as 1000? Anyone know what the problem is?
