You can't really do this unless you write your own USB printer driver so that your machine LOOKS LIKE a printer that the device can print to. Capturing the actual USB traffic won't do you any good because you'll be capturing the USB data along with the printer data.

Setting mailto

I try to set text (pulled from Database) into a HyperLink and set it for an email.
Here is the code I try to use for it, but it only sets the "mailto" as string in front of it.

<asp:HyperLink ID="email" runat="server"
Text='<%# String.Format("mailto:{0}", Eval("email")) %>'></asp:HyperLink>

Using CommandArgument and couldn't set it in the LocationByArea_ItemCommand either

This is what I tryed:

Protected Sub LocationByArea_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles LocationByArea.ItemCommand

If String.Compare(e.CommandName, "ListAreas", True) = 0 Then
Dim str As String = e.CommandArgument.ToString()
LocationAreas.SelectParameters("areaID").DefaultValue = e.CommandArgument.ToString()

For Each item As DataListItem In Me.DataList1.Items
Dim email As Object = CType(item.FindControl("email"), HyperLink)
email.NavigateUrl = "mailto:" & email.Text
Next
End If
End Sub

Any suggestions how I could solve this?

I'm currently posting the values in an HTML table as follows:
___________________________________________________
cid = Request.Form("stateabbr")

sql="SELECT State, CrossLinkFormID, DORFormID, FinalDraftDate, SubmissionDate, ApprovedDate, SubmissionNotes, AdditionalNotes FROM FormsTable WHERE State LIKE '" & cid & "%'"
rs.Open sql, conn
%>

Forms Submission for
<%Response.Write(cid)%>

<%
' Writing column headings

response.write("")%>
<%for each x in rs.Fields
response.write("")
next%>

'Writing Column values

<%do until rs.EOF%>
<%for each x in rs.Fields%>
<%next
rs.MoveNext%>

<%loop
rs.close
conn.close
%>

Select	" & x.name & "
	<% Response.Write ("<id=" &="" x.name="" "="">" & x.value) %>

_________________________________________________________________

After clicking the button "Select Forms", how can I grab the values/rows in the table where the check box is check and use an sql statement to add these values/rows into a new table?

Did you attribute this class and the sub appropriatly for use as a stored procedure? It doesn't look like it.

VB.Net Print Queue Enumeration

SQLDiablo17-Apr-07 5:47

17-Apr-07 5:47

I am writing an application that will globally add a print queue to a target PC. I can get lists from Active Directory of my print servers and my host PCs. What I'd like to do is have the user click on the print server, and my application will enumerate all print queues on that server and list them. The user will then select a print queue and a remote host, and click a button to install the printer. I can do everything except enumerate the print queues on the print server. If someone could please help with this, I'd greatly appreciate it Big Grin | :-D

. I am coding with Visual Studio .Net 2005 and VB .Net.

Search for 'WMICodeCreator'; I downloaded it from Microsoft and used it to do exactly what you are asking for.

I was able to get a list of printers on our print server and other needed information.

Ok, I almost have it working, except I'm now get a NullReferenceException error (Object not set to an instance of an object) on the line marked with a "-->". The error is directly following this paragraph, and my sub procedure is below the error. I call the sub like this: GetPrinters("name-of-server"). If you could help me out, I'd really appreciate it.

Well, I'm not sure...
Normally, I get the 'Name' attribute, but, my code is written to allow the user to select the desired attributes. When I selected 'ShareName', I had no errors.
Have you confirmed that you can get the sharename using the WMICodeCreator?

SQLDiablo18-Apr-07 7:52

18-Apr-07 7:52

Yeah, and the crazy thing is that I can see the list of sharenames in the creator, but when I execute the code (from the creator), it gives an access denied error, and fails.
