I just tried this on Windows 7 and it worked fine. Have you run it through the debugger to check the value of Application.StartupPath?

There was a component called XPBurn, which worked in XP. If it's not supported in Vista, then you need to search the web for samples in Vista, assuming it's even possible in Vista.

C# colors are ARGB, might Crystal Reports use RGB or BGR ?

Find MIN value in binding?

If I want to locate the minimum value for a column in a datatable I would use something like:

int minArrangementID = (int) debtorDataSet.PaymentArrangements.Compute("MIN(PaymentArrangementID)", "PaymentArrangementID > 0");

How can I find the minimum value within a binding please?

The type of a linq request

Hi;
I'm calling stored procedures using linq to sql to fill comboboxes from a database.
I have the method ConnectFilter() above that i want to refactor.
I started refactoring using FillComboWithData(ComboBox combo, string value, string display, DataClassesReferentielDataContext dc, XXXXX) above.
DataClassesReferentielDataContext is the Linq datacontext, it contains all the database mapped into objects.
By the way the stored procedures call many fields of many tables.
Here an example of a stored proc: P_ESS_Categorie_BIS.
I don't know how to enter the stored procedure as an argument (in place of XXXXX).
I think the argument should be an enumerable.
Thanks.

private DataClassesReferentielDataContext _dc = new DataClassesReferentielDataContext();
// The method I want to refactor
 private void ConnectFilter()
        {
            comboBoxCountryFilter.DataSource = _dc.P_ESS_Entite();
            comboBoxCountryFilter.ValueMember = "PAY_Code";
            comboBoxCountryFilter.DisplayMember = "PAY_Libelle";
            var statut = from s in _dc.TR_Statuts select s;
            comboBoxStatusFilter.DataSource = statut.ToArray();
            comboBoxStatusFilter.ValueMember = "STA_ID";
            comboBoxStatusFilter.DisplayMember = "STA_Libelle";
            comboBoxCategoryFilter.DataSource = _dc.P_ESS_Categorie_BIS((int) Selections.VueRefId);
            comboBoxCategoryFilter.ValueMember = "CAT_Code";

            comboBoxItPlanFilter.DisplayMember = "ITP_Libelle";

That's fine. I'm sure whatever language you speak natively, I can't speak as well as you speak English.

You can't, because the line numbers no longer exist when your code is compiled, the code does not exist in remotely the form you created it at that time. Also, it's not possible to jump execution to a random spot in the code, even the VS debugger cannot do that, it can only jump within the current method, and within the current try block. What you're asking is basically impossible, there is no chance of you being able to do it.

Take a look at the answer in this[^] thread on MSDN.

If you ignore the bit about selecting the RichTextBox from a Tab, you should be able to work it out.

[Edit]
Just found this code:

public void GoToLineAndColumn(int Line, int Column)
{
    Cursor.Current = Cursors.WaitCursor;

    int Offset = 0;
    int i = 0;

    foreach (String L in Lines)
    {
        if (i < Line - 1)
        {
            Offset += L.Length + 1;
        }
        else
        {
            break;
        }

        i++;
    }

    Select(Offset + Column - 1, 0);

    Cursor.Current = Cursors.Arrow;
}

Lines is RichTextBox.Lines property

You might also need the ScrollToCaret method, as I cannot remember if the Select(int, int) automatically brings it into view.

Hi all,
Could someone please tell me how to write code for the below situation?

When entering numbers into a text box
input 126 => output 1,26
input 1234 => output 12,34

It shouldn't accept letters and should allow me to leave textbox empty

Thanks in advance

As I only seek for a simple validation, I thought I could have a piece of code instead of using a custom control.

I'm sure it is a valuable reference for future needs. Thanks anyway
I still need a simple code to do it

Use the KeyUp Event to validate what's written in the TextBox and then alter the text.
But you'll have to write the code for it yourself.. Hmmm | :|
