object temp = arr[7];
arr[7] = arr[5];
arr[5] = temp;
|
|
|
|
|
This is done with a regular assignment:
arr[5] = arr[7];

You don't swap the buttons, you simply switch places on the buttons.
Get the value of the Location property from one of the controls and store in a temporary variable. Then get the value of the Location property from the other control and put in the Location property of the first control. Lastly, you get the value from the temporary variable and put in the Location property of the second control.

anybody plz tell me how how to use use mouse button-up & mouse button-down for drawing in paint program as we do in microsoft paint in windows....
|
|
|
|

The mouse move is the event that matters. You need to keep track of the co-ordinates it moves to, and use them to draw a line in your onPaint handler. You call Invalidate() to force a Paint event.

I am trying to create a application that when it is done updating the files that it need to it has the ability to delete itself. Is there a way of doing this, I thought that maybe if I could launch the program and run it entirely from ram that this would solve the problem.
So does anyone know how I would launch the program and run it from ram or is there a way to delete the executable when it is done?

Where else did you think your program is run from ? A program that is running, is in RAM, although the file is locked.

You may want to take a look at AppDomain.ShadowCopyFiles.
Simply speaking, with shadow copy enabled, the files holding your classes aren't locked anymore and thus can be deleted while their classes are still loaded in a running program.

Hello,
I am using C# dealing with DirectShow and need your help regarding this line of code. Can someone be kind enough and explain to me in plain english this line of code?
IMediaEventEx.GetEvent( out code, out p1, out p2, 0 );
My undrestanding is that the GetEvent method retrieves the next event notification from the event queue. using a txtlog I can see that the local variable "code" contains the Event Code. What I am confused about is, what I am getting on my local variables p1 and p2?
Using the txtlog I can see my p1 is series of digits. But what are they representing and do they have a particular format?
Thank you so much for your help and have a great day.

I have a standard windows forms project for which I have created a deployment project. In the deployment project I have added a pdf file which contains the documentation for the application.
In the deployment project I have added a shortcut to the pdf documentation file to the User's Program Menu.
How do I make it so that the icon for this shortcut is the default icon for pdf files? I know that I could add an icon to the Application Folder and have the shortcut file property point to it, however the icon used to represent a pdf document can be different on different target machines. Also, I am not sure how to obtain a pdf icon.
Thanks in advance
Adam

I am developing a program using asp.net 2.0. I am using C# as the programming language.
In this project I am connected to a SQLServer database (SQLServer 2005). I have created a stored procedure in this database and want to call it from C#, pass it some parameters and receive from it a return value.
I am not clear as to how to call it, pass the parameters and then access the return value.
I would appreciate any help/advise/suggestions/etc on this.
Thanks, Vern

Use an SqlCommand object:
<br />
<br />
using System.Data;<br />
using System.Data.SqlClient;<br />
<br />
SqlConnection objConnection = null;<br />
SqlCommand objCommand = null;<br />
<br />
objConnection = new SqlConnection(YOUR_CONNECTION_STRING);<br />
<br />
objCommand = new SqlCommand();<br />
objCommand.CommandType = CommandType.StoredProcedure;<br />
objCommand.Connection = objConnection;<br />
objCommand.Connection.Open();<br />
<br />
objCommand.Parameters.Add("@MyParam", MyParamValue);<br />
<br />
objCommand.ExecuteNonQuery();<br />
<br />
if (objCommand.Connection != null)<br />
{<br />
objCommand.Connection.Close();<br />
objCommand.Connection.Dispose();<br />
}<br />
<br />
if (objCommand != null)<br />
{<br />
objCommand.Dispose();<br />
objCommand = null;<br />
}<br />
<br />

kryzchek:
Thanks for the code. This code and other code I got from this site was very helpful.
Thanks again, Vern

See using System.Data.SqlClient;
Here is some code to play with. If you are returning a query use ExecuteReader instead.
SqlConnection connection = new SqlConnection("someConnectionString");
SqlCommand command = new SqlCommand();
command.Connection = connection;
command.CommandType = System.Data.CommandType.StoredProcedure;
command.CommandText = "stored procedure name");
SqlParameter parameterCustomerId = command.CreateParameter();
parameterCustomerId.DbType = System.Data.DbType.Int64;
parameterCustomerId.Direction = System.Data.ParameterDirection.Output;
command.ExecuteNonQuery();
I feel so silly, my code doesn't work!
parameterCustomerId.ParameterName = "@customerId";
command.Parameters.Add(parameterCustomerId);
needs to be added before the execute.
