Hello All,
I Have combo which have it'd dropdown style = dropdownlist. i.e. no body can
enter the data in it. I add some values in it on the folrm load like ....
cmbQ.Items.Clear();
cmbQ.Items.Add("A");
cmbQ.Items.Add("B");
cmbQ.Items.Add("C");
cmbQ.SelectedIndex = 0;
that means After Form Load the displayed value in cmbQ = A. Right.
Now my Problem ...
If save the values in database using cmbQ.text that means either A,B or C it is save.
But suppose the saved value is C.
when user open form again in edit mode, I want to display the selected values in cmbQ should be C.
How I can Do that...?
Remeber I Don't use DisplayMember, ValueMember property bcoz the ABC values are hardcoded.
I just to show it.
I allready tried
SelectedText
SelectedIndex
Text
SelectedValue
But unable to get desire output...?
I also Change the dropdown style before assign the values like
cmbQ.DropDownStyle = ComboBoxStyle.Simple;
cmbQ.SelectedText = ObjDS.Tables["Version"].Rows[0]["Version"].ToString();
cmbQ.Refresh();
cmbQ.DropDownStyle = ComboBoxStyle.DropDownList;
But Unable To Get Desire Output.
Please Help

i am new to programming, so plz help me.
I had design a wordpad or notepad editor, in this a user can fix the number of character in line, like if he sets chracter to 65 then only 65 chracters will appear in that line and further character will starts from next line.
so, at end of line instead of bringing the whole word to next lines it cuts the word(means if 65 character completed it force rest letters to next line). The word got cut.
so, how to solve this problem. So that, the whole word come to next line.
Help me.

You can check out one version of the WordWrap and LIne Breaking algorithm here:

you need to search first for the '/n' char which mean a new line. then you cut the word you need to transfer and put it in the apt place

Hi
I have a strange problem.In an application ,I have a login process and I'd like to show the progress of this process on a progress form using a progress bar and a label describing what is going on.Thus I put a progress form in my project and whenever this form is activated starts the login process and listens to a progress event that tells it to refresh the controls according to the progress.
There's a LoginFailedException in my app that is thrown whenever the username and/or the password is incorrect.I've handled this exception by showing a message box.Every time I debug my project using VS2003 IDE and provide some incorrect information It works fine and shows me the message box but when I exceute the exe file directly ,an unhandled exception is thrown just like there is no exception handler available.
What is wrong with my program?
please help me.

Here it is :
In my login form:
<br />
private void OnOKButtonClicked()<br />
{ <br />
try<br />
{<br />
this.Cursor=Cursors.WaitCursor;<br />
progressForm.Login(this.txtUsername.Text,this.txtPassword.Text) ;<br />
this.Cursor=Cursors.Default;<br />
this.Close();<br />
}<br />
catch(LoginFailedException)<br />
{ <br />
this.Cursor=Cursors.Default;<br />
MessageBox.Show("Invalid username and/or password.");<br />
}<br />
catch(Exception exp)<br />
{<br />
new ExceptionViewForm(exp).ShowDialog();<br />
}<br />
}
In my progress from:
<br />
internal static void Login(string username,string password)<br />
{<br />
progressForm frm=new progressForm() ;<br />
frm.username=username;<br />
frm.password=password;<br />
frm.ShowDialog(); <br />
}<br />
<br />
protected override void OnActivated(EventArgs e)<br />
{<br />
if(! activated)<br />
{ <br />
LoginForm.engine=<br />
LoginProcess.Instance.Login(this.username,this.password); <br />
}<br />

And what is the exception when it is run standalone? When you run it stand alone is it a debug or release build?

Good Day Sir/Maam,
<br />
DateTime StartTime = DateTime.Now;<br />
for (int i = 0; i <= List.Length - 2; i++)<br />
{<br />
for (int j = 0; j <= List.Length - 2 - i; j++)<br />
if (List[j + 1] < List[j])<br />
Swap(ref List[j], ref List[j + 1]);<br />
}<br />
DateTime EndTime = DateTime.Now;<br />
TimeSpan Duration = EndTime - StartTime;<br />
This is a bubble sort algorithm, I want to get the total duration of the sorting in Milliseconds. But the sorting was too fast that I got a 0 MS duration.
Can I get the duration in Nanoseconds using Timespan?

Ummmm.. no? It's a limitation of the hardware clock? (Others know more about it than I.)
But I'll add that you probably don't need to write your own sort algorithm (unless it's for a class project or something) because the ones built into .net are probably better than anything you or I could write.
See if something like System.Collections.Generic.List<int> will work for you, it has a Sort() method.
It just won't help you learn how to perform a sort.

|

Uhmm. I'm making a Sorting Emulator for educational purposes to present how a sorting algorithm works.
This is a class project for my course Analysis of Algorithms. Hehe.
Anyways, StopWatch class works great. Thanks! 6 ticks = 600 nanoseconds.
