the problem is im having a xls file and im opening it using workbook.open() and i select cell A10 and close it next time when i open the file i want the focus back on A1. i.e always the file is open the focus should be on cell A1 for that i used the macro which i stated in the previos thread. but i feel it would be better if i can do that also in the application.
below is the code

private void button1_Click(object sender, EventArgs e)
{
openexcel();
}

private static void openexcel()
{
Excel.Application xlApplication = new Excel.Application();
Excel.Workbooks xlBooks;
Excel.Worksheet xls;

xlBooks = xlApplication.Workbooks;
xlBooks.Open(Application.StartupPath + @"\ExcelFile01.xls", Type.Missing, false, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing);

xls = xlApplication.ActiveWorkbook.Worksheets[2] as Excel.Worksheet;
xls.Visible = Excel.XlSheetVisibility.xlSheetHidden;
xls = xlApplication.ActiveWorkbook.ActiveSheet as Excel.Worksheet;
xls.Rows.AutoFit();
//todo
focus back to cell A1

xlApplication.Visible = true;
System.Runtime.InteropServices.Marshal.ReleaseComObject(xls);
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlBooks);
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApplication);

}

Hi,

Wouldn't something like Cells(YourRow,YourColumn).Select work?

Kind regards,

Have a look Developers Guide to the Excel 2007 Application Object[^], most of it is in VB.NET, but that's just syntax ....

I'm sure that you'll find something useful there ....

Is this going to be the same excel file you'll be opening every time? You could put an 'AutoOpen' macro in the excel file (which would run anytime the file is opened, just enable macros when you open it) to do all this preliminary stuff you're doing in C#. It would be much easier in VBA anyway.

This should do it: Range.Activate Method[^] (Activates a single cell, which must be inside the current selection. To select a range of cells, use the Select method.)

Hi guys!

Maybe someone can help me with this:

I have a library C which controls a device and it's methods take enumerations as parameters.
Then I have a library B which references C and "wraps" the complex commands from library C in something useful and maintainable.
The last thing I have is an assembly A which does the UI stuff. It references ONLY library B.
Nevertheless B needs the values of the enumerations of C to control the device (and to fill comboboxes with the enum-Values)

I need a way to pass the information, which value of an enumeration is needed from A to B.
I do not want to reference C in A (that's how I would get the enumerations as well).

Which would be a good approach to solve this problem.

Help would really be appreciated!

You could just copy 'n paste the enum .. but that makes it harder to add/change values later (there are probably better solutions..)

Why not reference C in A? If B references C and A references B, then you have to distribute C with application A anyway. If you want A to have access to the values of the enumeration, referencing C is the 'right' and easiest way to go about it.

Thanks for your reply. I just hoped it would be possible to separate the C2 logic from the UI with the lib B as link.

I would put the enum in A; but you could put the enum in D.

Thanks for the hint, unfortunately I can't do this due to he fact, that lib C wasn't written by me.

Then write your own in B, and then translate.

Hi there,
I am quite new to C# and WPF especially. I have a form, with 2 listboxes on. The first looks up an xml file and gets some data items (themes), the next listbox is bound to the first, and gets some data (scenes) from inside the selected theme tag.

This works wonderfully.

I would now like to get the value of an element (FreeStyleCue) and use that in a c# function tied to the OnSelectionChanged handler.

However I cant work out for the life of me how to get the information from the FreeStyleCue tag.

Can anyone help me??

Here is the xml file.

<?xml version="1.0" encoding="utf-8" ?><br />
<themes><br />
  <theme name="Yellow" description="A yellow theme" order="1"><br />
    <scene name="PreShow" order ="1"><br />
      <description>For before the show yellow.</description><br />
      <FreeStyleCue>y12</FreeStyleCue><br />
    </scene><br />
    <scene name="Scenex" order ="1"><br />
      <description>During yellow show</description><br />
      <FreeStyleCue>y122</FreeStyleCue><br />
    </scene><br />
  </theme><br />
  <theme name="Blue" description="A blue theme" order="1"><br />
    <scene name="PreShow" order ="1"><br />
      <description>For before the show</description><br />
      <FreeStyleCue>b12</FreeStyleCue><br />
    </scene><br />
    <scene name="Scene1" order ="1"><br />
      <description>During Show</description><br />
      <FreeStyleCue>b122</FreeStyleCue><br />
    </scene><br />
  </theme><br />
</themes><br />

Here is the WPF XAML file

        {<br />
            <br />
            <br />
            SelectQueueInFS(SelectionID); //this is where i am stuck!!! <br />
        }<br />

I give u an example.

I have a ComboBox 'themesComboBox' decalared in XAML file. (Note the x:Name, instead of Name, so that we can refer the ComboBox from C#).

<ComboBox SelectedIndex="0" x:Name="themesComboBox" SelectionChanged="ThemeChanged">

The following is the method which handles the event.

void ThemeChanged(object sender,RoutedEventArgs args)
{
ComboBoxItem cbi =(ComboBoxItem)themesComboBox.SelectedItem;
string themeName = cbi.Content.ToString();
}

Modify the two lines in your program

<TextBlock Text="{Binding XPath=FreeStyleCue}" /> to

<TextBlock Text="{Binding XPath=FreeStyleCue}" x:Name='freeStyeleCueTextBox'/>

<ListBox Name="listboxScenes"
ItemsSource="{Binding ElementName=listboxTheme, Path=SelectedItem, UpdateSourceTrigger=PropertyChanged}"
ItemTemplate="{StaticResource dtScenes}" Height="650" SelectionChanged="listboxScenes_SelectionChanged"> to

<ListBox x:Name="listboxScenes"
ItemsSource="{Binding ElementName=listboxTheme, Path=SelectedItem, UpdateSourceTrigger=PropertyChanged}"
ItemTemplate="{StaticResource dtScenes}" Height="650" SelectionChanged="listboxScenes_SelectionChanged">

Now you can access the textbox and list box from your c# code.

Hope it will help you.

Hi there,

Thanks for the help. Most appreciated!
THe only thing is that I was using XML in the listbox so it outputs XML instead of a string.

I have included

using System.Xml;

and then the code is now

XmlNodeList FSQUES = ((XmlElement)listboxScenes.SelectedItem).GetElementsByTagName("FreeStyleCue");<br />
<br />
           foreach (XmlNode FreeStyleCue in FSQUES)<br />
           {<br />
               SelectQueueInFS(FreeStyleCue.InnerText);<br />
<br />
           }

Hope this helps someone.
