If there is only richtextbox on the tab and no other controls, you can access it like this: tabControlMain.TabPages[tabControlMain.TabPages.Count-1].Controls[0] Another way is to assign name to the richtextbox before you add it to the tab and access it through its name: tabControlMain.TabPages[tabControlMain.TabPages.Count-1].Controls["richtextboxname"]
Don't forget to cast it to richtextbox.

Hi,

Thanks for the reply. Something like this then:

RichTextBox text = (RichTextBox)tabControlMain.TabPages[tabControlMain.TabPages.Count - 1].Controls[0];

Before your response I came up with this (it works aswell, but don't know if I'm going about it correclty Confused | :confused:

)

public RichTextBox[] rtext = new RichTextBox[100];
...
// when adding a new tab and richtext box
rtext[tabControlMain.TabPages.Count - 1] = new RichTextBox();
tabControlMain.TabPages[tabControlMain.TabPages.Count - 1].Controls.Add(rtext[tabControlMain.TabPages.Count-1]);
...                   
// load the file from drive
rtext[tabControlMain.SelectedIndex].LoadFile(dlg.FileName, RichTextBoxStreamType.PlainText);

Anyway that is my version but I'm new to CSharp so I don't know if this is the correct way to go about it Blush | :O

Thanks again

There is no need to have a separate array of richtextboxes that hold the reference.

RichTextBox text = (RichTextBox)tabControlMain.TabPages[tabControlMain.TabPages.Count - 1].Controls[0];

Yes, you can get values from your DataTable. You could get them from either the DataGridView, or from the DataTable itself I'm just going to show you how to get them from the DataTable. Lets say you want to get all values from a specific column, here's how you would do it:

for (int rowIndex = 0; rowIndex < yourDataSet.yourDataTable.Rows.Count; rowIndex ++)
{
  for (int columnIndex = 0; columnIndex < yourDataSet.yourDataTable.Columns.Count; columnIndex ++)
  {
    Console.WriteLine(string.format("Row {0}, Column {1} cell value is {2} !", rowIndex.ToString(),
       columnIndex.ToString(), yourDataSet.yourDataTable.Rows[rowIndex][columnIndex].ToString()));
                                     // for columnIndex you can use the column name if you'd like.
  }
}

In C# is there any way to know the number of non null elements in an array?

As length property give complete number of elements in the array. But if only i want to know count of only not null values elements of the array what should be the method or property need to be used.

I don't think there's anything built in, so you'd probably have to iterate through the entire collection and keep a count yourself.

This is after ages I may be adding a comment to the thread, but thought like sharing info I had on my exp.
There are no built in libraries in dot net to convert from word to PDF, in this context its a good practise to use third party's like Abcpdf.dll where you can even embed images with paging in generated pdf.you can further refer to "http://dotnetf1.blogspot.com/2008/07/convert-word-doc-into-pdf-using-c-code.html" for third parties which are available for free of cost.

setting session as string

Hi
I have a string called db1 which contains a code value

I need to set this string as a global session for the page.
What is the syntax for this, I have tried

Session["gdb1"] = db1;

however the session appears to be blank??

thanks in advance

Re: setting session as string

Pete O'Hanlon3-Jan-08 22:31

Two thoughts.

1. Is db1 populated at this point? If it's null then the Session will still be empty.
2. Are you running a multi-core machine? If so, you can run into problems with state management if your state service is running "in process". To get round this, you need to run your session manager as either a Sql state service or ASP State Service.

Assuming that you want to run as the ASP.NET state service, if you look in your Services, you will see one of the services is called ASP.NET State Service. This needs to be running, and you must set your config file to run the sessionState as StateServer. Typically this would look something like

<sessionState mode="StateServer" 
	stateConnectionString="tcpip=dataserver:42424" 
        cookieless="false"
        timeout="20"/>

Session variables are not global, they are specific for the user.

If you want a global value, use an Application variable instead:

Application["gdb1"] = db1;

Hi
I have to limit the input in a textbox for the mobile number. There should be no spaces and it should allow a +27.

my regex expression is:

<asp:RegularExpressionValidator
ID="regExMobile" runat="server" ControlToValidate="tMobilePhoneNumber" Display="Dynamic"
ErrorMessage="The Number should not contain spaces" ValidationExpression="\+\b.*\d{10}"></asp:RegularExpressionValidator>

But this is not working if the number is saved as +27xxxxxxxxx and they want to remove the +27 then the error message is displayed. Can anyone advise me on what I am doing wrong as I am new to this

Could you describe exactly what the valid input is that you want in all it's different forms

i.e.
+27XXXXXXXXX where X is a number
or
0XXXXXXXXXXX where X is a number
or
+0XXXXXXXXXXX where X is a number

then also exactly describe what format you want the input to be saved in.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
