As far as I recall, the Code Project tutorial I referenced was written with C#.

Use "VB.NET and C# Comparison" cheat sheet from (I think) www.harding.edu[^] but in case it wasn't, Google for it.

This should help you to understand what is happening in both C# and VB.net, but as you are just learning, consider downloading the Microsoft PDF e-book that is available to registered users of vb.net 2005 Express Edition.

Also, you might like to get a copy of "VB.NET Fundamentals" from http://www.pdsa.com/[^] this is a free e-book that comes with source code. As I understand, you are required to register with them before they let you have a copy to download.

Hi there.

If you use an Access database here is an example on how to use it.

First add a reference to ADODB.dll

Declare database connection varaible as follow:

Private cnDatabase As ADODB.Connection

Open the database. Note that the DatabaseName must be the full path of the database.

cnDatabase = New ADODB.Connection
cnDatabase.Open(DatabaseName)

Fetch data from the Database:

Dim rsRecord As New ADODB.Recordset
Dim strSql As String
Dim tempValue As Object

strSql = "SELECT * FROM " & TableName

rsRecord.Open(strSql, cnDatabase)

With rsRecord
If Not .EOF Then
tempValue = .Fields("FieldName").Value
End If

.Close()
End With

rsRecord = Nothing

Save data to the database:

Dim rsRecord As New ADODB.Recordset
Dim strSql As String

strSql = "SELECT * FROM " & TableName

rsRecord.Open(strSql, cnDatabase, ADODB.CursorTypeEnum.adOpenKeyset,
ADODB.LockTypeEnum.adLockOptimistic)

With rsRecord
.AddNew()

.Fields("FieldName").Value = YourValue

.Update()

.Close()
End With

rsRecord = Nothing

Hope this wil help you.

Return Parameter in ADO.NET

Hi all

I'm moving an VB6 app to .NET and i'm faced with the following problem:

Having the following stored procedure in SQL SERVER 2000, that returns a dataset (Read only) AND has an OUTPUT parameter at same time, which of the command methods should i use, since it seems that ExecuteReader (Thats seems to be the only that returns a rowset) doesnt update the OUTPUT parameter.
Im I missing something?, Is there Any work Around?

'==============================================================================
ALTER PROCEDURE spGetResourceText (@frmName varchar(20),@MaxIndex int OUTPUT)
AS
SET NOCOUNT ON

SELECT @MaxIndex = Max(Id) FROM tblResourceText WHERE frmName = @frmName
SELECT * FROM tblResourceText WHERE frmName = @frmName

RETURN
'==============================================================================

Thanks in advance for your time!

Carlos,

I hope you want to receive 2 result sets. So you can use DataSet for executing your SQL procedure. Normally Dataset return result sets as Tables.

So from the above, you will get 2 tables, you can written the code like below and retrieve both the resultsets,

Dim DA As New SqlDataAdapter
Dim DS as new Dataset

DA.SelectCommand = {pass your Command object}
DA.Fill(DS)

dim intMaxIndex as integer
intMaxIndex = DS.Tables(0).Rows(0).Item(0)

For intIndex = 0 To DS.Tables(1).Rows.Count - 1
{within this loop you can get each record/field values by
DS.Tables(1).Rows(intIndex).Item({field name})}
Next

Best Regards,

Find Function? [modified]

Hello, I am new to VB and need help on a specific question.

I need to know if there is a find function in VB so that I can terminate a loop. Example, suppose I need to find all tildas (~) in a file from start to finish in MS-Word. I would like to use a find function (if it exist) in my test condition so that the program exits the loop when the last tilda is found. Below is a for loop that I hard coded to repeat so many times but I would prefer doing it a better way. Help is appreciated.

Sub test()
'
' test Macro
' Macro recorded 7/30/2006 by Harold-Wishes
'
    Selection.Find.ClearFormatting
    For Counter = 1 To 20
    
    With Selection.Find
        .Text = "'"
        .Replacement.Text = "'"
        .Forward = True
        .Wrap = wdFindContinue
        .Format = False
        .MatchCase = False
        .MatchWholeWord = False
        .MatchWildcards = False
        .MatchSoundsLike = False
        .MatchAllWordForms = False
    End With
    Selection.Find.Execute
    Selection.TypeText Text:="'"
    Next
End Sub

Hello,

Could you clarify?
I would like to remove the code below and have the loop stop when the last tilda is found. Currently I have it set to loop twenty times.

For Counter = 1 To 20

I know there is some boolean function for find, but I'm not getting the syntax correct.

Try using regular expression. Once your value has been found exit the loop. Here is an article in MSDN

You can't minimize a window using Javascript.

You can't maximize a window using Javascript. The closest is to set the window size to be the same as the screen size. Off the top of my head, something like: window.moveTo(0,0);window.resizeTo(screen.x, screen.y);

Use window.close(); to close the window.

i have a decimal number ina variable i want to convert it into hexa decimal
and i want to assign it into a target varable the problem is my target variable can hold only one byte so i want to to assign this hex number in byte by byte
that is if a=&h0fe2
i want to assign b=&h0f
c=&he2

thank you in advance

Decimal and hexadecimal are string representation of numbers. Are you really having a string representing the number, or are you just having a plain simple number?

I assume that you don't know what you are talking about Wink | ;)

, and that you have a 16 bit number, and want to split it into two 8 bit numbers (bytes):

a = &hfe2 ' the number 4066

b = a div 256 ' will contain the number 15, or &hf
c = a and 255 ' will contain the number 242, or &he2
