first learn to spell basic.
I would suggest working through a book like Visual Basic .NET in 24 hours or equivent dummy's guide book.
This should give you a foundation to start with.
Then pick yourself a simple project to hone your newly acquired skills.
If possible, attend evening classes at a local college. It usually helps if you learn with a group, because you can bounce ideas off each other.

I hate those 'learn x in y hours' books, they rarely do any good or explain concepts that are paramount for successful projects, even the smallest of such.

Yes, but they're a good starting point for the absolute beginner as they will cover some of the basic features of the IDE as well as the basics of the language in question.
I should have also said, move for the VB in 24 hours books to something like "Professional VB.NET" and don't rule out books on programming concepts including OOP and database design.

If you have literally no idea, a forum reply is not going to fix it for you. Your best bet is to search for a library, or buy one.

Anything you use is quite likely to use the Graphics.DrawPie method. It's quite simple when you break it down.

|

Look up the use of a Union Query to help you achieve this...
eg:
select 'January' as MonthName, MonthData from JanuaryTable
union
select 'February' as MonthName, MonthData from FebruaryTable

|
|

Surprisingly, he has a life and is not offering to accept your piecemeal work, to do for free.
Perhaps if you don't understand how to write basic SQL, you should buy a book on it ?

Hi guys
I have a simple bit of code which opens up Internet Explorer, navigates to a web page, selects a value from a drop down menu (options are either "Yes" or
"No") and submits the form.
The code works fine if it is selecting "Yes" however if I change it to "No"
it dosn't work. Here is my code:
*************************************************
strURL =
"http://corporate1.internal.standardlife.com/phoneline/Phnline.nsf/frmStaffUpdate"
Set objIE = CreateObject("InternetExplorer.Application")
objIE.Navigate strURL
objIE.Visible = False
While objIE.ReadyState <> 4
wscript.sleep 300
Wend
objIE.Document.all("kwdshowphoto").Value = "Yes"
Call objIE.Document.Forms(0).Submit
objIE.Quit
***************************************************
Here is part of the source code of the internal website, which relates to
the drop down:
<table border="0" width="100%" cellspacing="0" cellpadding="0"><a
width="100%" border="0" cellspacing="0" cellpadding="0">
<tr valign="top"><td class="sectionHead" width="350"><a width="1%"><img
width="359" height="1" src="/icons/ecblank.gif" border="0" alt=""><br>
My location data / PhoneLine photo</td><td class="sectionHead" ><a
width="100%"><img width="1" height="1" src="/icons/ecblank.gif" border="0"
alt=""><br>
<div align="right"><a href="javascript:PhonelineHelp();" class="globalNav"
title="launch phoneline help">Help</a> </div></td></tr>
<tr valign="top"><td width="350"><a width="1%"><img width="359" height="1"
src="/icons/ecblank.gif" border="0" alt=""><br>
</td><td ><a width="100%"><img width="1" height="1" src="/icons/ecblank.gif"
border="0" alt=""><br>
<br></td></tr>
<tr valign="top"><td class="labelText" width="350"><a width="1%"><img
width="359" height="1" src="/icons/ecblank.gif" border="0" alt=""><br>
Show my photo on Phoneline :</td><td class="dataText" ><a width="100%"><img
width="1" height="1" src="/icons/ecblank.gif" border="0" alt=""><br>
<font size="2">
<input name="%%Surrogate_kwdShowPhoto" type="hidden" value="1">
<select name="kwdShowPhoto">
<option>Yes
<option selected>No</select>
</font> </td></tr>
<tr valign="top"><td width="1%"><img width="359" height="1"
src="/icons/ecblank.gif" border="0" alt=""><br>
</td><td width="100%"><img width="1" height="1" src="/icons/ecblank.gif"
border="0" alt=""><br>
<br></td></tr>
Thanks in advance

This won't solve your issue, but you'd do better to handle the event of the state changing and respond to it, than doing this.

Does the value get changed to 'no' ? What does 'it doesn't work' mean ? What goes wrong ?

Besides what Christian said, as the default selected value is no, why not just submit the form directly if you want the value to be no?
My advice is free, and you may get what you paid for.

Hi Guys
Thanks for the replies. The default value is "Yes".
When I run the line of code which attempts to set the value to "No" the drop down goes blank. This is not an option when you manually click it. When the form is submitted it must revert to the default "Yes" due to it being blank.
Thanks

OK, so your code plain doesn't work at all. In that case, why didn't you say so ?

What? If you read my first post, you would see it does work if I am changing the value from "no" to "yes".
Why are you trying to be smug and cheeky?
|
|
|
|
|
Anyway...
How about using the index (If "Yes" = 0 and "No"= 1 or something) instead of the literal values ?
My advice is free, and you may get what you paid for.

Hi Johan
I tried using the 0 and 1 values, but this dosn't work either. Thanks for your suggestion though
|
|
|
|

I would try the values 1 and 2 instead.

I get this error and I'm not sure why. I am trying to parse a tab seperated file. The first 10 lines parse correctly and on the 11th it throws the above error. Always on the 11th line and I've tried several different files of varying length and content. I am not closing or disposing the StreamReader before the file is read out entirely. Below is my reading function:
Public Function readNextLine(ByRef buffer As Single()) As Boolean
Dim i As Integer
Dim tempString As String()
tempString = Split(fStreamReader.ReadLine(), cDelim)
ReDim buffer(tempString.Length - 2)
For i = 0 To tempString.Length - 2
If (IsNumeric(tempString(i))) Then
buffer(i) = CSng(tempString(i))
Else
buffer(i) = 0
End If
Next
readNextLine = True
End Function
The above function is called in the following while loop:
Private Sub file_to_dataset(ByVal fileInfo As System.IO.FileInfo)
Dim singleRead As Single() = {0}
fileParser = New clsFileParser(fileInfo, vbTab)
dsLogData.Clear()
While fileParser.peek() <> -1
If (fileParser.readNextLine(singleRead)) Then
If (singleRead.Length = dsLogData.Columns.Count) Then
dsLogData.Rows.Add(singleRead)
End If
End If
End While
End Sub
I've tried changing the buffer size on the streamReader, but it seems to have no effect.

I found the source of the disposal. Trying to determine the number of columns in the tab separated file by using this statement:
Using newStreamReader As StreamReader = New StreamReader(fStream)
getColumnCount = Split(newStreamReader.ReadLine(), cDelim).Length
End Using
fstream is what I use to open the StreamReader fStreamReader. By invoking the using statement with fStream it appearantly closes the fStream after it's done with it, which causes fStreamReader's baseobject to be closed. This causes the program to throw the ObjectDisposalException.

Ive had a google about nexted if statements but failing to find what i need, or just am not awake to find it 
So here is an example of what i need help with
if textbox1.text = "example" then
if textbox2.text = "another example then
so on.....
END IF
I have done it it java just not sure in VB, in a quick way, when system runs the if statement, if the first if passes then go onto the second if statement.
Could anyone help me out on the correct syntax?
|
|
|
|

You seem on the right path, I don't understand the statement..
If x = 1 Then
If y = 2 Then
If z = 3 Then
z = 4
y = 5
x = 6
End If
End If
End If
Assume
x = 1
y = 2
z = 4
Then the first two If statements pass as true but the last If statement, the test on if z = 3 fails, so x,y and z never get changed past 1,2 and 4 respectively.
Did this help?
