I have a few ideas but by-no-means a definate answer.
1. Look to the Ricoh company for a solution. Either there website or contacting them.
2. Look into the DLLs that are installed with the printer and try to compose a hack of some-sort that will allow you to change the property.
Not what your looking for but might help you get started.

Thank you. I was thinking the same way. I was asked to do that this way by our networking guys but it made no sense to me. We are using Citrix that means everyone shares the driver. Even if I create code it will only work for the first person signed in. Everybody else will use his last settings and if he changes it to color everyone will be printing color. Finding out the config file and setting black and white as a defatult and when making config read only makes more sense.
Thank you very much for reply.

I have successfully create a windows service application and installer in Visual Studio 2005. I would like the service to be installed as a windows user. My current installer does this by setting the Service Process Installer Account to user. However during the installation a popup box appears that looks very out of place with my installation package. Does anyone know how I can create a custom interface within the installer that will allow me to enter the account information and the pass this informatio to the installer class so this pop up does not appear.
Thanks in advance.

In my current project there is a requirement of console applications to0 be used with window services in order to process xml files.
I don’t know much about console application. I want to know what is the use of console application ? How we can use it with window services? Or can we build window services through console applications?
|

1) what is it: it's basically a DOS enabled windows application with no gui front end to it. it opens a dos window and through code you can, for example, interact with the user via dos...asking questions in the dos window.
Rough explanation I know...
2) how can it be used: I assume the requirement is that the console application is supposed to process the xml file and then the window service is supposed to use the results? if the assumption is correct, you don't have to use a console app to do it. you can put a file watcher inside the windows service and have it look at a specific directory and when a file appears process it under the thread of the event of the watcher.

copyds1to2()
End Sub
Public Sub copyds1to2()
Dim cmdBuilder As FbCommandBuilder = New FbCommandBuilder(adapter2)
ds2 = ds.Copy
adapter.Update(ds2)
End Sub
Public Sub loadDS2()
Try
ds2 = New DataSet("Destination")
con2 = New FbConnection(connectionString2)
con2.Open()

adapter.Fill(ds, "Studets") ' copy ds change
adapter.Fill(dt)
DataGrid1.DataSource = dt

With adapter2

.InsertCommand = cmdBuilder.GetInsertCommand()
End With

First off, let me just say that this question is just for information purposes. (I'm kinda curious as to why this is happening)
I have a wierd error with the VB program I have access to here.
The error is in the code and has to do with some of the standard tabControl methods.
What happens is that if that there is a method that returns an in depending on what letter is put into it. The returned int is then used to select which tab page is shown by the control.
To get the code to work it goes something like this:
Dim index As New Integer
tabIndex = Groups.ConvertToNumber(Attribute.Group)
If Not Groups.ConvertToNumber(Attribute.Group) = -1 Then
FunctionPicker.SelectedTab = FunctionPicker.TabPages(tabIndex)
End If
The above code works. However if I change the code to this:
If Not Groups.ConvertToNumber(Attribute.Group) = -1 Then
FunctionPicker.SelectedTab = FunctionPicker.TabPages(Groups.ConvertToNumber(Attribute.Group))
End If
It no longer works, when it should. (And as far as I know worked in previous versions)
Any idea as to why this happens?

Disregard previous reply if you saw it... Eyes playing tricks on me.
Don't know.
But here's my 2 cents.
We don't really know what ".ConvertToNumber" returns. We're assuming it's a user-written function and returns something numeric, but...
But the whole thing becomes moot if the code is written properly.
Suggestion: To make the code more efficient, don't execute the expensive function more than once if you can help it.
Execute it, get the validated results in tabIndex, (preferably within a Try block, using System.Convert), so you know exactly what you're dealing with, and then just use the index.

Hi there.
The ConvertToNumber always returns a number. The number returned will always be from between -1 and 7. (-1 being the Error number)
I've been stepping through the program with Visual Studios debugger, So I can tell ya that it is definately returning a number. For the testing I was doing, it always returned the number 2. However if I looked at the FunctionPicker.SelectedTab it always states that it contains nothing.
But it always works correctly if I put it into an pass the results of ConvertToNumber into an integer before passing it into the TabPages method.
Hence why I'm calling it a wierd bug

That is definitely a puzzler. If I get some time later tonight I will set one up and see if I can reproduce it.

Munty -
Couldn't reproduce it.
I set up a form with a tab control with 8 pages, various overloaded functions to return integers and singles (which I then cast to Int) etc, buttons to set the preconditions and call each scenario, ...
Got the right tab selected every time.
You're right. That's a weird bug.

Please kindly assist.

It's not peppy code if you need to look at the entire harddrive but this will get you through it if you know where to start.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If bFindFile("C:\", "abcd.txt") Then
MsgBox("Yep") 'show form1
Else
MsgBox("Nope") 'show form2
End If
End Sub
Private Function bFindFile(ByVal sStartFolder As String, ByVal sFileName As String) As Boolean
Dim bFound As Boolean = False
GetDirectories(sStartFolder, sFileName, bFound)
Return bFound
End Function
Private Sub GetDirectories(ByVal sPath As String, ByVal sFileName As String, ByRef bFound As Boolean)
For Each sDir As String In Directory.GetDirectories(sPath)
bFound = bCheckFiles(sDir, sFileName)
If bFound Then Exit Sub 'we found it...get out of the loop
GetDirectories(sDir, sFileName, bfound)
If bFound Then Exit Sub 'we found it...get out of the loop
Next
End Sub
Private Function bCheckFiles(ByVal sPath As String, ByVal sFileName As String) As Boolean
Dim saFiles() As String = Directory.GetFiles(sPath)
sFileName = sFileName.ToLower
For Each sFile As String In saFiles
If Mid(sFile, InStrRev(sFile, "\") + 1).ToLower = sFileName Then Return True
Next
System.Windows.Forms.Application.DoEvents() 'so your PC does not lock up looking for the file
Return False
End Function
