Hi,

Please find below an sql query which I have used for one of my projects. Replace the columns and fields with yours and check whether it will suits with your requirement:

insert into stalericstemp1(RIC_Name, No_of_Days, Last_Update_Date, Next_Update_Date, PE_Fid1, HeadEnd_Fid1383, Location_Fid836, CTBTR_BKDG, Ric_Added_Date, Record_Entry_Date, StaleRic, Message, Updated_Date, File_no) select * from StaleRicsTemp where next_update_date > '11/25/2007' and next_update_date < '12/03/2007'

order by ric_name

The * in the select query of second table contains exactly the same field and datatype of first table. Please let me know if it helps you.

Smile | :)

It looks like you are missing a parenthesis just before the SELECT.

I have used a RichTextBox in the past, and simply required that the end user has the microsoft language pack installed. That way, the OS deals with the language exclusively (changing keyboard input and the like), which makes this kind of operation transparent to your application.

Hello everybody, I encounter a problem and need your help.

In a MDI application of C#, I want to show a PDF file in a child form. I have added a PDF browser to the child form and change it to pulic, just like below:
public AxAcroPDFLib.AxAcroPDF pdfBrowser;

When the MDI load, my code likes below:

Code:

private void MDIFrm_Load(object sender, EventArgs e)<br />
        {<br />
            ChildFrm myChildFrm = new ChildFrm();<br />
            myChildFrm.pdfBrowser.LoadFile("C:\\dev\\linux-i18n-intro.pdf");<br />
            myChildFrm.MdiParent = this;<br />
            myChildFrm.Show();<br />
        }

However,I can not see the PDF content in the Child form,but if I set the ChildFrm as the strartup object,it will show PDF correctly.

Could anyone give some suggestions?
Thanks very much!

I can only guess:

maybe the pdfBrowser loads an empty file on Form_Load?
Anyway: you should not put the pdfBrowser on a public property - better give the path to the constructor and set it in the form.

Anyway he problem seems to be with the pdfBrowser - maybe try using the webbrowser-control to show your files?

How to change the initial value of DataSet.CaseSensitive (in .NET 2.0, it is false by default)

I have written many methods that using DataSet.
Now, I realise that I need the property 'CaseSensitive' of every DataSet instance to be 'true'. I don't want to change every source file to make it. Is there any simple way to make each DataSet instance created with 'CaseSensive = true'? e.g. envirment setting

I am using Visual Studio 2005 (.NET 2.0).

Thank you.

About Combobox's ValueMember and DisplayMember

Zerox MXI5-Dec-07 20:07

When attaching a datasource to a combobox, one can choose to specify its display and value member. For instance...

class PhoneContact
{
... // omitted

public string Name { get { return this.name; } set { this.name = value; }
public string Number { get { return this.number; } set { this.number = value; }
}

PhoneContact[] arr;

combobox1.DataSource = arr;
combobox1.DisplayMember = "Name";
combobox1.ValueMember = "Number";

I wanted the drop down list to show a combination of Name and Number concatenated together but the show just the number in the textbox field of the combobox. How do I do that?

drop down list will show like this,

Name1, Number1
Name2, Number2
..., ...

And after you select one of them, it only shows number in the textbox field and not the concatenated one.

Rationale:

You have a list of numbers in your phone book, I decided to allow the user to choose one of the numbers from the phonebook in a lookup manner via the combobox. Or if the number does not exist, one can key in any number not from the phonebook into the combobox textbox field. However, the combobox will only show the value from a single field specified by DisplayMember, if I had made "Number" as the display member, a drop-down list of numbers will be meaningless to the end user when he can't even tell who the number belongs to. And if I put the DisplayMember as "Name", somehow, the end user would not be able to verify if the number associated to the name is correct or wrong.

And ideas? Thanks

This is very easy in your example: just add a property - let's say

<br />
public string DisplayValue<br />
{ get { return Name + ", " + Number; } }<br />

to your PhoneContact class and use

<br />
combobox1.DisplayMember="DisplayValue";<br />

that's it.

Yes I've tried that myself,

the only catch is that after you have selected one of values in that concatenated form from the drop down list, the textbox field is populated with "Name, Number", where what I would liked was just the number itself in the textbox field.

Eventually, what I need is just the number value where for some reason can't just get from SelectedValue property.

In a case where no number exists in the drop down list, SelectedValue property will be null or empty if some other number was entered into the textbox field of the combobox.

string number = string.Empty;

If (combobox1.SelectedValue == null)
number = combobox1.Text;
else
number = combobox1.SelectedValue.ToString();

And that's exactly why after the selection from the drop down list, I only want a number and not the concatenated string of "Name, Number" to be in the number variable.

then use

<br />
number = combobox1.Text.Substring(0,combobox1.Text.IndexOf(','));<br />

in the case where SelectedValue == null !
