You should never store a date, a time or a datetime as a string if there are alternatives. Most databases do have some kind of date or datetime field type, so use it. A database cares about storing data, not formatting it; your app must deal with formatting data when presented to the user.

This[^] little article may tell you more about datetime type.

I have two pieces of advice for you:

1.
I would suggest you select, buy and study an introductory book on C#. You have been asking a number of pretty elementary questions lately, reading a book would teach you much more in a shorter time. Visit a book store (if none around, look at Amazon), and get to it.

2.
Learn to help yourself, use Google and MSDN. Operations on files are most likely handled by the File class. Maybe WriteAllText() is your friend. Look them up, read about it, and try.

The formats supported by the Image class are listed here[^].

Simply change your OpenFileDialog Filter to include those you are interested in.

You currently have:

openFileDialog1.Filter = "All Image Files|*.bmp;*.ico;*.cur|All files (*.*)|*.*";

To add a filter for PNG files (for example) simply add the filename template between 'cur' and the '|' before 'All Files', not forgetting to separate it by a semi-colon.

openFileDialog1.Filter = "All Image Files|*.bmp;*.ico;*.cur<sup><big>;*.png</big></sup>|All files (*.*)|*.*";

I have tried to make my additions stand out by superscripting it.

Have a go with the others yourself.

accessing child thread from the parent thread

i have two threads in my application , the child thread holds an open socket and update a textbox in the parent thread , now i want to
send some text from the parent thread to the other end through the child socket. but i'm having the problem of accessing it , any idea about this , how to access this socket .

Re: accessing child thread from the parent thread

jschell7-Dec-10 10:13

You have a class A with data (socket)
You have another class B that you want to use with class A (call a method which sends data.)

So class B must have access to the instance of class A and it must call the method.

Nothing in the above has anything to do with threads because threads has nothing to do with it.

What does matter for threads is that you want to insure that both threads do not attempt to use the socket at the same time. A simple lock deals with that.

How to scroll ListView from your source code?

I have a ListView control with LargeIcon view. Its width allows exactly only single item in a row to be displayed. Thus it may contain upto Nx1 items from two dimensional point of view.

How to automatically scroll to a given item?

You could use pInvoke to set the scroll position.

Hi Everybody,

Please help me to solve my problem.

I am developing an window application in C#, in that I have designed some crystal report. All this crystal reports are running properly on my development machine. But When deployed at client machine, whenever the user views the report it ask for login name and password.
I have given logon information through my code using TableLogInfo. But still While viewing the report, it asks for Login name and password.

Please Provide Me The Better Solution You Have.

Thanks & Regards
Sanket Patil.

Hello Alok Sharma Ji,

Thanks Once Again For The Reply. What I Have Done In My Code Is Here.

ALLEXE = new PayrollSoft.Report.AllowanceExempt();

                    tblinfo = new TableLogOnInfo();
                    foreach (Table Atbl in ALLEXE.Database.Tables)
                    {
                        tblinfo = Atbl.LogOnInfo;
                        tblinfo.ConnectionInfo.ServerName = objcon.GetServerName();
                        tblinfo.ConnectionInfo.DatabaseName = objcon.GetDatabaseName();
                        tblinfo.ConnectionInfo.UserID = objcon.GetUserId();
                        tblinfo.ConnectionInfo.Password = objcon.GetPassword();
                        if (objcon.GetTrustedConnection().ToUpper().Equals("YES"))
                            tblinfo.ConnectionInfo.IntegratedSecurity = true;
                        else
                            tblinfo.ConnectionInfo.IntegratedSecurity = false;
                        Atbl.ApplyLogOnInfo(tblinfo);
                    }

                    ALLEXE.RecordSelectionFormula = "{ALLOW_EXEMPT.IA_CM_CODE}= " + Masters.MainMaster.CMPID + " AND {ALLOW_EXEMPT.IA_YEAR}=" + cmbYear.Text.Remove(4, 1) + " AND {ALLOW_EXEMPT.IA_DELETE}=false " + Query;
                    StrCompanyName = objcon.GetColumn("Select CM_COMP_NAME from COMPANY_SETTING WHERE CM_COMP_ID=" + Masters.MainMaster.CMPID + "");
                    ALLEXE.SetParameterValue("companyname", StrCompanyName);
                    crystalReportViewer2.ReportSource = ALLEXE;
                    this.Show();

Hope This Is The Right Way to Provide Logon Information To Report.

Thanks & Regards
