I have created a window service which accesses a folder on a seperate system and writes a file into it.

Everyone has been granted access on that folder

Now when i install service with user account it is able to create file into it,
but when i install service with either local system,local service or network service it is anot able to write file into it. it says "Access denied" to that folder.

Is there a way that i can write file into that folder with either local system,local service or network service.

Since i have tried with all possible right granted to that folder.

"everyone" does not include IUSR/IWAM/ASP.NET

try giving asp.net user write access to that folder (if it still fails try iusr/iwam also)

I have a window service which is accessing a shared folder on another server.

how does ASP.Net user will solve this problem as it is for IIS.

Also i want to access folder by installing services with "Local System" status

My apologies...I misread window service as webservice. you can use impersionation. have the window service logon as someone that does have access or falls under the group everyone when writing to the shared folder...

I have impersonated using WMI,

and while checking directory i use

system.io.Directory.Exists("Shared folder path")

it gives me exception "Access Denied" cause when i register service as Local System it uses Local system a/c to get access to the folder and that's why it says "Access Denied"
but when i Register it with User account it uses that a/c to get access which is in Everyone.

The work around is that register the service with User a/c but how to access folder with service registered "Local system"

please help !!!!

oh i think i understand, you want the selected item on button press to have the same value as the next or previous item.

If that is the case:
Make sure your listbox selectionmode = selectionmode.multiextended

Select all:

ListBox1().SelectionMode = SelectionMode.MultiExtended<br />
    For i As Integer = 0 To Me.ListBox1.Items.Count - 1<br />
        Me.ListBox1.SetSelected(i, True)<br />
    Next

Change current to same as previous:

        ListBox1().SelectionMode = SelectionMode.One<br />
        Dim Selected As Integer = Me.ListBox1.SelectedIndex<br />
        Dim newItem As String<br />
<br />
        If Me.ListBox1.SelectedIndex > 0 Then<br />
            newItem = Me.ListBox1.Items.Item(Selected - 1)<br />
            Me.ListBox1.Items.RemoveAt(Selected)<br />
            Me.ListBox1.Items.Insert(Selected, newItem)<br />
            Me.ListBox1.SelectedIndex = Selected<br />
        End If

Change current to same as next:

    ListBox1().SelectionMode = SelectionMode.One<br />
        Dim Selected As Integer = Me.ListBox1.SelectedIndex<br />
        Dim newItem As String<br />
<br />
        If Me.ListBox1.SelectedIndex < Me.ListBox1.Items.Count - 1 Then<br />
            newItem = Me.ListBox1.Items.Item(Selected + 1)<br />
            Me.ListBox1.Items.RemoveAt(Selected)<br />
            Me.ListBox1.Items.Insert(Selected, newItem)<br />
            Me.ListBox1.SelectedIndex = Selected<br />
        End If

If you click only on child nodes how will you ever be able to use the expand/collapse feature of treeviews? This is one of the advantages of using a treeview.

Not saying it's impossible, just think it's a bit weird. What exactly are you trying to do? Maybe I can help.

multiple currencies in one datagrid column

Elwood Baker13-Dec-06 3:52

Elwood Baker

13-Dec-06 3:52

I have a datagridview in which I have a list of items some of which are priced in Dollars and some in sterling is there any way to format the columns accordingly.

I have a second column which can be used to pick the currency up from eg.

Roller skates 22.40 USD
Fishing Rod 34 GBP

what I would like to see is

Roller skates $22.40 USD
Fishing Rod £34.00 GBP

I can format the Whole column if they are the same currency using
.CellTemplate.Style.Format = "C2"
I assume this picks up the default currency? If I can alter the currency Symbol for an individual cell then I'm Ok.

Thanks for any help

Hi
I'm populating an xml file from a dataset. There are some columns that sometimes don't have a value. The problem is that those column names don't appear in the xml file when they don't have a value. How do I get those columns to still appear in the xml file and not be ignored?

Thanks,

i am creating a notepad in vs05 and i am trying to display the name of the file at the top of the screen when i open a file from desktop. this is the code i've got so far, instead of the file name it displays openfiledialog1. this is very anoying, any help would be appreciated. thanks

this is code i got:

Dim name As String = OpenFileDialog1.FileName

With OpenFileDialog1
.Title = "select file"
.InitialDirectory = "U:\MyDocuments"
.DefaultExt = "rtf"
.Filter = "rich text files(*.rtf)|*.rtf"
.FilterIndex = 1
End With

OpenFileDialog1.ShowDialog()

If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then

rtb1.LoadFile(OpenFileDialog1.FileName)
Else
MsgBox.show("unknown error during file read")

End If

Me.Text = name

Replace Me.Text = name with Me.Text = OpenFileDialog1.FileName.

Actually, you would be better writing this section like this:

Dim fileName As String

If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
    fileName = OpenFileDialog1.FileName
End If

If fileName <> String.Empty Then
    rtb1.LoadFile(fileName)
    Me.Text = fileName
End If

Don't tell somebody that there was an unknown error just because they clicked Cancel in a dialog box. It is bad form.

Exporting crystal report to excel issue

Hi,
I am trying to export a crystal report to excel format in aspx page using vb as the code behind. I have published the crystal report in the BusinessObjects server and loading in the page load event. I can able to load the crystal report using the below code,

<br />
 Dim mySessionMgr As SessionMgr = New SessionMgr<br />
 Dim myEnterpriseSession As EnterpriseSession = mySessionMgr.Logon(uname,pwd,servername, AuthType)<br />
 Dim myEnterpriseService As EnterpriseService = myEnterpriseSession.GetService("InfoStore")<br />
 Dim myInfoStore As InfoStore = New InfoStore(myEnterpriseService)<br />
 myEnterpriseService = myEnterpriseSession.GetService("PSReportFactory")<br />
 Dim psrfObject As Object = myEnterpriseService.Interface<br />
 Dim myPSReportFactory As PSReportFactory = CType(psrfObject, PSReportFactory)<br />
 Dim queryString As String = "Select SI_ID, SI_NAME, SI_PARENTID From CI_INFOOBJECTS " _& "Where SI_KIND='CrystalReport' and SI_INSTANCE=0 " _<br />
                        & "And SI_NAME = 'Report1'"<br />
 Dim myInfoObjects As InfoObjects = myInfoStore.Query(queryString)<br />
 Dim myInfoObject As InfoObject = myInfoObjects(1)<br />
 Dim myReportSource As ReportSource = myPSReportFactory.OpenReportSource(myInfoObject.ID)<br />
<br />
 Session("my_rptsrc") = myReportSource<br />
 CrystalReportViewer1.ReportSource = myReportSource <br />

But the export options is not working for the instance of my report(myReportSource)

<br />
  Dim myExportOptions As New CrystalDecisions.Shared.ExportOptions<br />
  Dim myDiskFileDestinationOptions As                                     CrystalDecisions.Shared.DiskFileDestinationOptions<br />
  Dim myExportFile As String = "Report1.rpt"<br />
  myDiskFileDestinationOptions = New CrystalDecisions.Shared.DiskFileDestinationOptions<br />
  myDiskFileDestinationOptions.DiskFileName = myExportFile<br />
  <br />
  myExportOptions = myReportSource.ExportOptions<br />

I need to get the export options as in the above code but i m not able to get that(Export option is not available for the instance).

<br />
With myExportOptions<br />
   .DestinationOptions = myDiskFileDestinationOptions<br />
   .ExportDestinationType = .ExportDestinationType.DiskFile<br />
   .ExportFormatType = .ExportFormatType.Excel<br />
End With<br />
    myReportSource.Export()<br />

In the above line also export function is not available for the instance myReportSource.

<br />
    Response.ClearContent()<br />
    Response.ClearHeaders()<br />
    Response.ContentType = "application/ms-xls"<br />
    Response.WriteFile(myExportFile)<br />
    Response.Flush()<br />
    Response.Close()<br />

I need help regarding this....

For listbox:

Select All: It is necessary to switch modes on select all

ListBox1().SelectionMode = SelectionMode.MultiSimple<br />
    For i As Integer = 0 To Me.ListBox1.Items.Count - 1<br />
        Me.ListBox1.SetSelected(i, True)<br />
    Next

Select Previous:

ListBox1().SelectionMode = SelectionMode.One<br />
If Me.ListBox1.SelectedIndex > 0 Then<br />
    Me.ListBox1.SelectedIndex = Me.ListBox1.SelectedIndex - 1<br />
End If

Select Next:

ListBox1().SelectionMode = SelectionMode.One<br />
     If Me.ListBox1.SelectedIndex < Me.ListBox1.Items.Count - 1 Then<br />
         Me.ListBox1.SelectedIndex = Me.ListBox1.SelectedIndex + 1<br />
     End If<br />

Make sure your connection string is setup correctly. This site is a good reference for that: http://www.connectionstrings.com[^]

If it is correct, make sure your user and password are the correct letter case (if your user/password is all lower case, make sure it is lower case in your connection string too)

Hope this helps.
