There should be no problem by name. Could you upload an image of the Console listing the name (option 2.) ? Use the snipping tool for that purpose.

rproffitt commented: I agree but I've seen folk go down this rabbit hole and the name wasn't in the data. +15

┬┐Are you entering the complete name? The select command is NOT case sensitive, but if you want to use the percent wildcard '%', the function would be then:

    Function Find_Device_By_Name(name As String) As Boolean
        Try
            ' See if the desired device shows up in the device manager. '
            Dim info As Management.ManagementObject
            Dim search As New System.Management.ManagementObjectSearcher(
                "SELECT * FROM Win32_PnPEntity WHERE Name LIKE '%" + name + "%'")
            For Each info In search.Get()
                Dim devname As String = CType(info("Name"), String)
                Dim ID As String = CType(info("DeviceID"), String)
                Console.WriteLine("Device ID is: " + ID.ToString)
                Console.WriteLine("       name=" + devname)

BTW you may cast from one type to another by means of DirectCast() or CType().

Vendor ID (VID) and Product (ID) is not the same as serial number. Two equal devices from the same vendor will have the same VID & PID because are the same product from the same vendor, but different serial numbers.
I have made same changes to the code so you can find also a device by name:

As you may know, each device has a unique Vendor Identifier (VID) and a Product Identifier (PID). If, for example, I want to know if the mouse is connected, what shall I do? I can list all the devices with their VID and PID. Then unplug the mouse, list again all the devices and compare with the former list and see which device is missing: the missing device will tell me the mouse's VID and PID.
Once I know the VID and PID, it will be possible to detect if the mouse is connected or not.

Imports System.Management

You should know by now or take a programming course: call the function passing the name of the device as argument.

In Visual Studio go to the Solution Explorer and right click over "References". It will look something like this:

A dialog window will be opened. Select "Framework" on the left pane, and click the check box for System.Management.

Accept and the error should disappear.

If you want to list only USB devices, you may do:

Of course if you're not coding in VBasic like me, most probably you'll have to escape the slash /. So the pattern becomes collections\/(?!\/|shirts|tea|[\w]+\/products)

xrjf 178

Assuming products (if present) is after the second / character like in
collections/shirts/products/tee-shirt,
collections(/(?!/|shirts|tea|[\w]+/products)) seems to work.

EvolutionFallen commented: Perfect! Just what I was looking for. +9
xrjf 178

Try collections\/col(\d{2,}|[^23])(?!\/products), because (\d{2,}|[^23]) will allow 2 or more numbers (as in col22, col21) or 1 number other than 2 or 3 (col1, col4, col5 but not col2 nor col3).

I'm not sure if each time can be a withdraw of 1 unit, but in that case, calling anotherTransct() from menu(), then menu() from anotherTransact() and repeating this same process enough times, there could be a stack overflow.

Is it possible for you to change lines 58 and 59 from:

ra1 =  rap[j-1];
ra1 = ra1/100.0;

to:

ra1 =  rap[j-1];
printf("DEBUG: ra1 is %lf\n", ra1);
ra1 = ra1/100.0;
printf("DEBUG: ra1 is %lf\n", ra1);

and debug again?

xrjf 178

Another possibility is to assure the operation in line 59: ra1 = ra1/100.0; maybe double precision in 32 and 64 bit machines do not match the same.

xrjf 178

Where is rap[ ] assigned a value? You should look there because the value of ra1comes from rap[ ], so if the values in ra1differ it's that rap[ ]values are already coming different from some other code, not the one you show.

Setting a session variable in javascript is not possible. Javascript executes on client side while php (php session variable) executes on server side, i.e. generaly on different machines.

Then call by means of XMLHttpRequest another php that grabs the phone number and any other data to record what is necessary.

             xhr.open('POST', '/server/getPhone.php', true);
             //Send the header 
             xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

             xhr.onreadystatechange = function() {//Call a function when the state changes.
             if(xhr.readyState == XMLHttpRequest.DONE && xhr.status == 200) {
             // Request finished. Do processing here.
             }
             xhr.send("phone="+urlencode(element.value)+"&foo=bar");

          }
      }

</script>

One way could be to assign the value to a hidden input label. For example:

<?php
 $_SESSION['num']='4567890123';
?>

<!DOCTYPE html>

<html>

<body>

<script>

      function checkmax(element) {

          if(element.value.length == 9){

              var vvc = element.value;

              element.value =document.forms['myForm'].elements['h1'].value;

//alert(vvc);
          }
      }

</script>

<form name="myForm" onsubmit="myPhp.php">

<input  type="text" id="dCell" 

    value="Cellphone Number"
    maxlength="10"
    onkeypress="checkmax(this)"
    name="CellphoneNumber2"
    id="cCell"
    onblur="checkmax(this)"
    onfocus="if (this.value = '') {this.value = 'Cellphone Number';}" required>

<input name="h1" type="hidden" value="<?php echo $_SESSION['num'] ?>">
</form>
</body>
</html>

I agree in that the only way I can see is to submit the form back to the server. Something like:

<!DOCTYPE html>
<html>
<body>
<script>
  function chkLen() {
  if(document.getElementById("dCell").value.length =10)
    document.getElementById("myForm").submit(); 
}
</script>
<form name="myForm" onsubmit="myPhp.php">
<input id="dCell" type="text" onChange="chkLen();" value="<?php echo $_SESSION['mySessionIDHere'];?>" />
</form>
</body>
</html>

I'm not gonna give a neg. rep. point, not even discuss what does lambda syntax look like in any specific language. Just that if this is a vb.net thread it's not a c# or not even asp.net. Isn't it?

Six thousand rows doesn't seem so much, unless having constant calls to the function.

Imports System.Linq

Public Class Properties
    Private Sub Properties_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Try
            Dim A1() As A = {New A(1, "name1", "address1", "email1@email.com", "1234", "NY"),
                            New A(2, "name2", "address2", "email2@email.com", "5678", "LA"),
                            New A(3, "name3", "address3", "email3@email.com", "9012", "XX")}
            Dim q = (From p In A1 Select ID = p.ID,
                    value = p.Name + "|" + p.Address + "|" + p.email + "|" + p.phone + "|" + p.city).ToDictionary(

@ddanbe why don't express lambda expressions in VB.NET instead of c#?

Do you mean somewhat like this?:

Imports System.Linq

Public Class Properties
    Private Sub Properties_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Try
            Dim A1() As A = {New A(1, "name1", "address1"),
                            New A(2, "name2", "address2"),
                            New A(3, "name3", "address3")}
            Dim q = (From p In A1 Select p.ID, p.Address).ToDictionary(Function(x) x.ID, Function(x) x.Address)
        Catch ex As Exception

        End Try
    End Sub
End Class
Class A
    Public ID As Int32
    Public Name As String
    Public Address As String
    Public Sub New(Id As Int32, Name As String, Address As String)
        Me.ID = Id
        Me.Name = Name
        Me.Address = Address
    End Sub
End Class
