So how is that formula working out for you?? Now you've got a project that you can't do, because everything was already done for you in the past, and you think that having someone else do your project for you will help you learn?? It didn't work before, so why do you think it's magically going to work now??
By the way, we don't do projects for people around here. If you want your code written for you, go hire a guy on RentACoder.com.

So, you expect to be a "qualified" developer and get paid a decent wage without learning how to code. Good plan. I jut hope you get some good, hard technical tests at the interviews.
I have one consolation, you are based in the USA so the chances are I'm not going to have to do your work for you in one of my contracts.

Hello all,
I have MDI Application in which i am displaying crystal reports.
For that i have created a mdi child form. in which ReportViewer control is used to display reports.
Now in my app, there would be many reports. so, do i need to create that many chile mdi forms and add reportviewer in all these forms?
or else can i use single form and reportviewer to disaply all forms?
and if yes.... how?
because it is MDI application, it wont allow me to open multiple instances of single form. but, user may want to view multiple reports without closing other.
any idea?
Thanx.......!

I used to do this before changing to RS.
Have a form with a viewer only
Create and test your report in CR and save it as a .RPT file. Report should be based on stored procedure or at least a paramaterised query (I always used procs).
In VB create a report (CR) using the .RPT file name (can't remember the details)
Pass in the parameters as CR parameter array
Connect the table objects in the report to the database
Pass the report object to the viewer
Show the MDI form.
Never underestimate the power of human stupidity

Hi,
I want to include/create a chart in my program which displays titles of x and y axis and then saves the chart/graph as an image file. What would be the robust way to do that!!
Thanks,
Aman

hi,
may this Create Column Chart Help you.
for save chart use following statement
AxChartSpace1.ExportPicture("C:\abc.jpg", "Jpg", 640, 400)
hope this helps

You would either have to create a new user control or you would have to use a third-party control.

Google for "ZedGraph". It's a free graphing library that will probably have the type of chart you're looking for.

Thanks Dave for the tip. It worked for my application; however, do you know the statement for saving a ZedGraph chart/graph as an image (jpg, bmp etc.)!

Nope. I've never used the library. That's a question for the people who made it.

Trying to get the title and artist data from the id3v1 in a .mp3 file
id3v1 info = http://www.id3.org/ID3v1
Heres more code:
Private Sub bAddFolder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bAddFolder.Click
For Each filePath As String In IO.Directory.GetFiles(DirListBox1.Path, "*.mp3", IO.SearchOption.AllDirectories)
Dim Title(30) As Byte
Dim Artist(30) As Byte
Dim mp As FileStream = New FileStream(filePath, FileMode.Open)
mp.Seek(-125, SeekOrigin.End)
mp.Read(Title, 0, 30)
mp.Seek(-95, SeekOrigin.End)
mp.Read(Artist, 0, 30)
mp.Close()
Dim TxtTitle As String = System.Text.Encoding.Default.GetString(Title)
Dim TxtArtist As String = System.Text.Encoding.Default.GetString(Artist)
fMain.ListView1.Items.Add(TxtArtist + " - " + TxtTitle).SubItems.Add(filePath)
Next
End Sub
Whats happening is it doesn't seem to be reading the data correctly....I get blanks in my listview or weird characters or just the artist and no title....all the mp3's i am testing have both the artist and title data in them (i checked through winamp)

You have ignored the return value from the method call. The method returns the number of bytes that was actually read, and that can be less than the requested number of bytes. If the number of bytes read is less than the request number of bytes, you have to repeat the call to get the rest of the data until you have got all the data.
Despite everything, the person most likely to be fooling you next is yourself.

hi! i'm new to vb .net..i want to calculate a power, i want to do it in a function..i'm having a hard time with arguments and parameters as well as with the return value.
please help! i have 2 text boxes for accepting inputs for base and exponent.
Public Class Power
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim base, exp As Integer
base = Val(text1.Text)
exp = Val(text2.Text)
MessageBox.Show("Power: " & Power(base, exp)) //how about this??
End Sub
Function Power(ByVal x As Integer, ByVal y As Integer)
Dim pow, i As Integer
Select Case y
Case 1
MessageBox.Show(x & " raised to " & y & " is 1")
Case 0
MessageBox.Show(x & " raised to " & y & " is 0")
End Select
For i = 2 To y
Return pow = pow * x //is this correct??
i += 1
Next
Return ??what/how??
End Function
End Class

Have you tryed:
dim Number as integer = 2
dim Power as integer = 5
dim x as integer = Number ^ Power

You should specify the return type of the method, otherwise the return type will be Object.
Function Power(ByVal x As Integer, ByVal y As Integer) As Integer
ay3ssah wrote: Case 1
MessageBox.Show(x & " raised to " & y & " is 1")
That is not correct. x raised to 1 is x, not 1.
ay3ssah wrote: Case 0
MessageBox.Show(x & " raised to " & y & " is 0")
That is not correct. x raised to 0 is 1, not 0.
ay3ssah wrote: Return pow = pow * x //is this correct??
No, that is not correct. As you don't initialise the pow variable, it will be zero from start. Anything times zero is still zero, so the final result will always be zero.
ay3ssah wrote: i += 1
If you increment the loop variable in the loop, that will have the same effect as having a loop with step 2. The For...Next statement increments the loop variable automatically.

Return pow

whoaa!!! i did all of that but i erased it..hehe
did i mention that the calculation should be done in a loop? not with Math.pow or ^ sign..
is it ok to return one argument even if there are two parameters?
thank you so much! il try all of that later..

You can only return one value from a function, unless you use byref parameters or you create your own class or structure, or you return an array

How do I write code for?
Catch Format Exception (invalid input)
This is for a program that only has you selecting from 0-3 and anything else is an invalid input.

You only want the user to be able to enter 0, 1, 2, or 3 in a text box?
