Hello..
Can anybody tell me how to give readonly access to some of the rows in datagrid while leaving others as non-readonly. I have binded a dataset with the datagrid.
Plz reply urgently
Take care

Please give me some idea on how the Key_Press Event of a Form can recognize an input from a device (in particular, a barcode reader-like device). Some says it is through an 'ID tag'. Where can I find the ID Tag of a device? Or if it's not the answer, how is the best solution? Thanks for any help...

That depends on the device. That depends on the hardware and how it's connected to the machine. If it's USB, then it'll show up as a USB device. If it's connected to the keyboard, it'll just stuff keystrokes exactly like the keyboard does. If it's attached to the serial port, then you'll have to read data comming from the port.
The KeyPress event, obviously, will only work if the device is attached to the keyboard port, or if the device has a driver that reads what port it's on, then generates keyboard messages.

I mean sir what if the time-tracking device is not connected directly at the back of the CPU used by HR. Instead, it is located somehow quite far from any computer, and it was just connected through Local Area Network. How can then I configure the KeyPress Event of Form in VB.NET for every input from that device?
|
|
|
|
|
You can't! Since the device is on the network, there will be no keypresses coming from it. You really need to get ahold of the documentation for this device and find out how to communicate with it. Precisely, how does this device send it's data to the host? Without knowing that, you have no chance of getting any information from the device.

Hello again,
I need some help with a simple OLEDB query. I need to return one value from an Access database. the code below is a snapshot of what i have so far.
Imports System.Data.OleDb<br />
Public Class Prices<br />
<br />
Public Shared ReadOnly Property Price(ByVal Name As String, ByVal Size As String) As Double<br />
Get<br />
Dim connString As String = "Data Source=""C:\Documents and Settings\user\" & _<br />
"My Documents\Visual Studio Projects\Quiznos Register\Assoc. Files\Quiznos.mdb"";" & _<<br />
"Jet OLEDB:Engine Type=5;" & _<br />
"Provider=""Microsoft.Jet.OLEDB.4.0"";" & _<br />
"persist security info=False;"<br />
Dim conn As New OleDbConnection(connString)<br />
Dim cmdGetPrice As New OleDbCommand("SELECT Products.Price FROM Products Products WHERE" & _<br />
"(Products.Name='Classic Italian') AND (Products.Size='Small')", conn)<br />
<br />
Try<br />
If conn.State <> ConnectionState.Open Then<br />
conn.Open()<br />
End If<br />
Catch ex As OleDbException<br />
MsgBox(ae.Message)<br />
End Try<br />
<br />
Select Case Name<br />
Case "Classic Italian"<br />
Select Case Size<br />
Case "Small"<br />
Price = cmdGetPrice.ExecuteNonQuery '<----- This is where it gives me the error.<br />
'other cases for other sizes<br />
End Select<br />
' other cases<br />
End Select<br />
Return Price<br />
<br />
conn.Close()<br />
<br />
End Get<br />
End Property<br />
End Class
at the line "Price = cmdGetPrice.ExecuteNonQuery", i get an InvalidOperationException. what do i need to do to return this single value
thanks ahead of time,
stephen

Hello!
It seems that your query is returning more than one record....
Try out this query..
SELECT Price FROM Products WHERE
(Name='Classic Italian') AND (Size='Small')
This is coz no need to give alias when working with a single table.
Also check the table 'Products' for rows having same 'Name' and'Size'.
If it doesnt work......try to use a dataset to give value to varialble 'Price'

Hi there,
is there a way using VB.Net to create a pop-up in a webform to let the user enter data and sends it to another form?
|
|
|
|
|
Not in VB.NET. You have to do it in JavaScript in the HTML itself. Then post it using the same methods that any ASP.NET page does. But that's a question for the ASP.NET Forum.

To give my local aspx app the access it needs to create a Windows Media Services object on a remote server, I need to tell it what user to run as. (I am following these instructions: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmsrvsdk/htm/creatingremoteserver.asp)
How do I configue IIS so that the aspx runs as a specific user?

Hello I have a question concerning datagrids.
How can I show hierarchical data in a datagrid using a relation without requiring the users to click on the relation hyperlink?
Can I set the DataMember Property in some way?
Any help will be appreciated
Thanks in advance

When an XP user switches user (ie doesnt log off) their programs remain running. This is true for VB applications also, they continue executing script. However if the calling of a DLL procedure is part of the script, the application ignores the command and carries on until the user logs back on and then the application resumes sending and receiving data to/from the DLL. Does anyone have any suggestions on how to continue this process even when the user is not strictly logged on (without scripting the DLL procedure in VB)?
Cheers in advance.

This should not be the case. What functions are you calling? What are you expecting them to do?

Keylogging functions. I am using user32.dll to log key strokes and I am attepting to log them over user accounts.
|
|
|
|

No wonder. You can't do that. An application running under your account cannot see what going on in another logon session, period, end of story.
The only thing that can see into another session is a Windows Service.

Right so I cannot see into the windows sessions - only windows can do that. So would it be possible to sort of integrate the keylogging application with the OS and make it a sort of system application which COULD see over different user sessions?
Cheers

Like I said, write your app as a Windows Service. You'll also have to write into your app a low level keyboard hook. This is the only way to see keyboard messages before they're dispatched to the user session.
