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?

View 2 RepliesI'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 report that i'd like to display an Image for each record. But not all records have an image. The problem I have is that the last image is then repeated in the next record.
I would like to know how to have any empty field display a default image.

Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
Me.Image21.Properties("Picture") = Me.PhotoLink
End Sub
Photolink is a textfield and Image21 is an Image.

I'm creating a game using vb.net and whenever the user inputs something to my program it displays the time and the time displayed until the user inputs something again the the time changes. I have my program display each individual timestamp but I would like to know if I would be able to save the values and all display at the end of my game in a new form.
The code I have is the following:
(in timer1=tmrReadInputs):
For I = 0 To 3
If (Convert.ToInt32(DataValue) And CInt((2 ^ I))) <> 0 Then
lblBitVal(I).Text = "1"
Else
lblBitVal(I).Text = "0"
TextBox1.Text = Trim(Format(Now, "hh:mm:ss tt"))
End If
Next I
tmrReadInputs.Start()
So when the value changes from 1 to 0, the textbox displays the time. How can I save the different time stamp values? I heard StreamWriter can work but I keep trying that and it doesn't work

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�m having trouble with the picturbox control, my problem in its basic form is:I have a picture Box array consisting of 9 picture boxes each with a different image in loaded at run time these are names 0.jpg to 8.jpg I then have 2 more picture Boxes named ansOne and ansTwo. I have made it so you can drag the images of these numbers to either of these picture Boxes It this next part I�m having trouble with:
I then want to have thoughs images represent a sum so when a button is clicked it adds or multiplies thoughs images together but as numbers ("badly put I know ")I am very unshore of where to start. After the image has been dragged how would I know what image has been dragged and turn that in to its integer equilivent?I had thought of using split string or something similar to just get the number before the .jpg so tried picAnsOne.imageLocation but that throghs a null reference And that�s as far as I have got.

I have manage, to allow user to browse through their files and insert an image path into a local database. The program will then retrieve the image from the image path and will be stored into ImageList. The Listview1 will then add the pictures of Imagelist into the ListView1.Items. Now my question, how can i retrieve back the path of the image when the users click on the selected image from the ListView?
