yes, it does not appear in services window, thus you can not start it from your application programatically.
what custom actions do I need to add to setup?
in setup program I only add service application exe. that setups the service in windows programs, but it did not get registered.
in MSDN help it says to add custom action to setup, but what is the action? installutil.exe myservice.exe?

I have to practice for my final exam and they give me this and I'm struggling, can someone help?
Web Service:
The web service must expose two methods which will each multiply or add two integers.
The methods must return an integer value, specifying the result. Call methods "Multiply" and "add"
for example, when passing the integer 3 and 8 to Multiply method, it should return 24.
Client:
A console client that let the user input an integer.
The user must also specify whether to multiply or add. Then using the algorithm described below, process the number by calling
the Web service methods to obtain a result.
Example-
input = 5
if user choose to multiply, the following should be performed:
5 x 4 x 3 x 2 x 1
the result is
120
if the user choose to add, the following should be performed:
5 + 4 + 3 + 2 + 1
the result is
15
A loop in the main program should be used, and each iteration the appropriate Web method should be called.
I Know I must use a bubble sort, but I have no clue to implement it....

Why? What on earth are you going to sort?

That I've got to see! "For security, all console output has been sorted into alphabetical order..."

so, the strucure is easy:
public int Add(int p1, int p2)
{
return p1 + p2;
}
and the same for multiply - but you knew that or it wouldn't be a final exam...

A loop in the main program should be used, and each iteration the appropriate Web method should be called.
So the progam logic is along the lines of:
1) read in a number
2) decide wether to add or multiply (assume Add for this example)
3) set temporary variable "result" to zero.
4) loop while input greater than zero.
5) each time round the loop, add input to result, and then reduce input by one.
6) print result.
What's the bit you are having problems with?

I really appreciate that you are helping, but its not necessary to mock me  , my instructor told me I must use a bubble sort.
I didn't understand why because it didn't make sense... I am still new at programming but take it very seriously.
The logic you just gave me is great thanks, just needed the idea.
what do you mean "reduce the input by one"?
|
|
|
|
|
I'm sorry, I wasn't mocking you. I assumed it was a mistake on your part in the original post and the made a joke of it. Please accept my apologies if I caused any offence. 
I don't see where a bubble sort would be used here: I suggest you ask your tutor for clarification if you can.
Brink Fourie wrote: what do you mean "reduce the input by one"?
Because you will be going round a loop checking each time that you haven't got to the end ("while input greater than zero") you need to reduce the loop count (and the number you are adding or multiplying) each time. Otherwise you will never get out of the loop!
"input--" or "input -= 1" or "input = input - 1" all work for me!
My word! it's a lot less typing to implement the program than it is to describe it like this!
You may want to fine tune the logic to give sensible results for negative inputs...

hahaha no it's fine just a communication fault then.
Thank for your help! I really do appreceate it!
AND it makes sense now without a bubble sort!!! hahahahaha

Hello,
I'm working on Windows application c#
i have form1 which contain data gridview to view the content of table from sql database.
i've enabled edit, delete in the gridview, and then i've added two queries one for update and the other for delete through MyDataSet1.xsd page.
now after updating and/or deleting any record i wanna click on a button to confirm user that the operation done. but i don't know how to save updating or deleting!!
any help guys?

You can use DataSet by these step
1) Fill the table in DataSet from SqlDataAdapter.
2) Assign DataSource to dataSet. DefaultViewManager
E.g: dgv.DataSource = ds.DefaultViewManager
3) GetChanges
DataSet dsMyChanges = ds.GetChanges();

could you please give me an example? coz i didn't get the idea

I don't have time to write full example to you. I extracted some code in my project. Hope that you can get my point. If you have questions, add my skype nick: binh_vu54321
1) Fill the table in DataSet from SqlDataAdapter.
private DataTable dtGetMPNs = new DataTable();
private DataSet dsGetMPNs = new DataSet();
if(dsGetMPNs.Tables.Contains("GetMPNs"))
dsGetMPNs.Tables["GetMPNs"].Clear();
daGetMPNs.Fill(dsGetMPNs,"GetMPNs");
2) Assign DataSource to dataSet. DefaultViewManager
dgvMPNs.DataSource = dsGetMPNs.DefaultViewManager;
dgvMPNs.DataSource = dsGetMPNs.Tables["GetMPNs"];
3) GetChanges
In Save change functions
DataSet dsMyChanges = dsGetMPNs.GetChanges();
if (dsMyChanges != null)
{
for (int i = 0; i < dsMyChanges.Tables["GetMPNs"].Rows.Count; i++)
{
}
}

Hi..
i have to draw three types of lines
- Constant Line
- Linear Line
- Quadratic Line.
Whats the difference between these three types of line.
i have draw the simple line by doing this.
OnPaint()<br />
{<br />
Graphics g;<br />
g = this.CreateGraphics();<br />
g.DrawLine(Pens.Red, 10,10,30,30);<br />
}
If sumone know plz reply..

I just spent ages working this out: GOOGLE.
Try typing "Constant line" into the search box - oh, look, "constant line graph" could that be one?
Then try "Linear line" - my, it's clever this, "linear line grapH" is a sugestion!
Perhaps "Quadratic line" - WOW! That was soooooo difficult!

I think they're not three kinds of lines. They are three expression for graph. Constant line is a point , linear line is a straight line, and quadratic line is a parabol.

|

well ok.. u mean that if user wana draw the linear line it will be a straight line and if the user wana draw a constant line it will be only a point and nothing else? is it? and the third one that is parabola..and it means that in which ever direction the mouse is moved it should draw parabola..?? will u plz tell em i right or not?
Actualy sumone told me this..
constant — This distribution will place an equal amount of paint at each pixel within the airbrush’s radius.
linear — This distribution will place a linearly decreasing amount of paint at each pixel as you move away from the center point. So at the center point, you will have full intensity of paint, whereas at radius pixels away from the center, no paint will be put on the canvas.
quadratic — This distribution will place a quadratically decreasing amount of paint at each pixel as you move away from the center point (i.e., the amount of paint used as you move away from the center decreases with the square of the distance). So, as with the linear distribution, the center point will have full paint intensity, whereas at radius pixels away from the center, almost no paint will be put on the canvas. There can be multiple ways to write the quadratic distribution. (Note: Your quadratic function should at least satisfy the property that when the distance x from the center of the circle is zero, the value of your function is "1", when the distance x is halfway to the radius, the value of your function is "1/4", and when the distance x is greater than or equal to the radius of your brush, the value of your function should be zero.)
i realy dnt understand these three points especially the last one..like how will decrease the intensity of the color..?? what i know is that v have a pen and assign sum color to it. like
Pen myPen = new Pen(Color.Red);
then how i will decrease the intensity of this color..??

Sorry, maybe I'm wrong because I just guest that. Actually, I cann't search any article about that. So sorry

All painting should be handled by the Paint handler, which has a PainEventArgs parameter, yielding a ready made Graphics. Creating your own Graphics does not make sense as it is expenive, slow, and needs a Dispose() call.

sory it was not in OnPaint() i just type the code and write it by mistake. its in MouseMove(). so thats y i create the graphics object in that function thats all.. but my question is still there.. actually i have to make a program in which user can draw linear line, constant line and quadratic line on mouse movement by clicking right or left buttons.. i dnt exactly know the difference between them..

Hi All,
I have to write a code for refreshing multiple databases at a time. The steps which it has to perform for refreshing databases are :
1. Source Server database backup.
2. Target Server database backup.
3. Capture user information.
3. Terminate active DB user .
4. Restore Database on target.
5. Drop existing user.
6. Re-create users.
7. Map users to the logins.
Can i write a stored procedure in c # itself to make this happen? If yes, please let me know how.
Thanks,
Vikas

Are you talking about taking a backup of the database ?
|
|
|
|
|
Everything you specified is possible in stored procs ... Just to clarify, if you have Source and Target databases in the same instance of SQL server.
Create statements to in a single batch and make a stored procedure. Compile that in Master and access each database from there .
|
|
|
|
|
You can write store procedure in C# with Managed Code and after that you have to deploy dll to server
