Thanks for the information. I thought that was going to be the answer but I need to double check.

I do not believe that the Express Edition support Add-ins.

Here are some of my articles.
Hope this helps!

Joseph,

Thanks for helping me out. I figured that the Express Edition did not support Add-ins but I had to make sure.

Thanks,

I couldn't find anything when I looked for this last month, but maybe you will have better luck! (I did find some limited resources that tell you the states that match zip codes for the US, Germany, and Canada (Provinces in Canada))

But that means adding the VisualBasic assembly to your projects and makes you feel dirty

*shudders and scrubs to get clean again*

hehe, but seriously thats a good answer Smile | :)

Hi,

In C# "IsNumeric" method is not available. You can do its manually using "char.IsNumber() or char.IsDigit()" in KeyPress events.

Here is the code snippet:

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (!char.IsNumber(e.KeyChar))
e.Handled = true;
}

Thanks,

OK - so you assume here that 42.03 is not a number.

Deja View - the feeling that you've seen this post before.

Hi,

Thanks for your reply.

I was checked only integer value. You can check "." and other special characters seperatly for double value.

Here is code snippet for double value:

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
TextBox txtBox = sender as TextBox;

if (e.KeyChar == '\b') { return; }

if (Char.IsDigit(e.KeyChar))
{
string amount = txtBox.Text;
int pos = txtBox.Text.IndexOf('.');

if ((pos > 0) & (amount.Length > 10))
{
e.Handled = true;
return;
}

if ((pos == -1) & (amount.Length > 7))
{
e.Handled = true;
return;
}

if ((pos > 0) & (txtBox.SelectionStart > pos))
{
amount = amount.Substring(pos, amount.Length - pos);
if (amount.Length > 2)
e.Handled = true;
}
else
e.Handled = false;
}
else if (e.KeyChar == '.')
{
if (txtBox.Text.IndexOf('.') > 0)
e.Handled = true;
}
else
e.Handled = true;

}

This code support eight integer value and two decimal digits.

Please let me know this will help for you.

Thanks,
S.Gopal.

You know you can add a reference to Microsoft.VisualBasic and do the equivilent call (Microsoft.VisualBasic.Information.IsNumeric) right?

How to copy all listbox items to cipboard?

Hello everybody,

I'm new here and beginner in C#. I have a question for you,please.
I have a listbox,and I want to copy all items to clipboard.

private void btnCopy_Click(object sender, EventArgs e)
{
for (int i = 0; i < lstAll.Items.Count; i++)
{
lstAll.SetSelected(i, true);
}
Clipboard.SetDataObject(lstAll.SelectedItems.ToString(), true);
}

this is the output: System.Windows.Forms.ListBox+SelectedObjectCollection
What I am doing wrong here? Sigh | :sigh:

Please help!!!

For a start, do you really want to select everything in the list box also? (You're thinking about how a user might do this, not how to do it programmatically)

Also, what do you actually want to appear in the clipboard? The list box has no idea about the clipboard so you have to format the data for it.

What you might want to do is create a StringBuilder and build up a list of the items with an Environment.NewLine at the end of each item, rather than selecting all the items in the list box.

Yes, I want to select everything in the listbox as I gathered all the info I need from other listboxes in this final one(lstAll). and now I want to select all items in listbox and copy to clipboard:

private void btnCopy_Click(object sender, EventArgs e)<br />
        {<br />
           StringBuilder strAll = new StringBuilder();<br />
            <br />
            for (int j = 0; j < lstAll.Items.Count; j++)<br />
            {               <br />
                lstAll.SetSelected(j, true);

But I don't now what should I put here before:

Clipboard.SetDataObject(strAll.ToString(), true);

Thank you in advance for your answer(s)!

You haven't answered the question: Do you really want to select everything in the list box. You are selecting the contents of the list box with apparently no purpose.

foreach(object item in lstAll)
{
    strAll.Append(item.ToString());
    strAll.Append(Environment.NewLine);
}
