<input type =”text” name=”date”><br>
<input type=”submit”>

Dim strDate , blnValid , dteDate
If Request.ServerVariables(“CONTENT_LENGTH”) <>0 Then
strDate = Trim(Request.Form(“date”))
‘check and see if the user entry is a date
If isDate(strDate) Then
dteDate = CDate(strDate)
‘set variable to true
blnValid = True
‘display invalid date message
Response.Write “You entered an invalid date”

Text Counter

Now create a folder called counters or you can call it something else if you want just remember and change the code above . Now create a text file called counter1.txt and enter whatever you wish to start the count at.

<%@ Language=VBScript %>
Dim fso
Set fso = Server.CreateObject(“Scripting.FileSystemObject”)
//this is the path to your counter1.txt file
counter = Server.MapPath(“/counters”) & “\counter1.txt”
//open the text file
Set InStream = fso.OpenTextFile(counter , 1, False)
oldCount = Trim(InStream.ReadLine)
//increment the oldcount by 1 and store in newcount
newCount = oldCount + 1
Set OutStream = fso.CreateTextFile(counter, True)
//copy newcount to the text file

Now you would place the folllowing where you want the counter to appear on your site

<%= newCount%>

Saving a CSV file to a database

Create a database in access called stock.mdb .

Now create a table like in the image in figure 1 and save this as stock

stock database

stock database

Now ensure that the last price , change , open price , daily high , daily low fields all have the field size set as Double , this is because the data is fractional and if you use the default Field size for a Number data type in Access this will give you a Long Integer and you will lose some of the data.

<!– #include file =””–>

‘declare variables for the database
Dim objConn , objRS
‘create instance of the Connection object
Set objConn = Server.CreateObject(“ADODB.Connection”)
‘open our stock database
objConn.Open “DBQ=” & Server.MapPath(“stock.mdb”) & “;Driver={Microsoft Access Driver (*.mdb)}”
‘create instance of the recordset object

‘open the file
Set objFile = objFSO.OpenTextFile(strURL)
‘while we are not at the end of the file

‘store the contents of the file in strText

‘close and destroy objects
