yep, that's mathematically equivalent to mine. It too calls zero a power of two.

Haven't solved it yet. We are profiling it over several days to get a better picture. Will let you know what happens.

An alternative approach could be:
private static bool IsPowerOf2(double number)
{
double value = Math.Log(number, 2);
return value == Convert.ToDouble(Convert.ToInt32(value));
}

Hi,

<br />
for (int cnt = 0; cnt <= DataGridView1.Rows.Count - 1; cnt++)<br />
{<br />
DataGridView.Rows[cnt].Cells["ColSelect"].Value = true;<br />
}<br />
1. Where ColSelect is your column name.
2. If you want to de-select just write false instead of true.
3. And if you want to know which row is checked and which is not then
<br />
for (int index = DataGridView1.Rows.Count - 1; index >= 0; index--)<br />
{<br />
if (Convert.ToBoolean(DataGridView1.Rows[index].Cells[0].Value))<br />
{<br />
"Selected"<br />
}<br />
else<br />
{<br />
"Not Selected"<br />
}<br />
}
<br />
:-D <br />
<br />

Hi,
I am writing my first control and would like to create an event so the form the control is sitting on can pick up user activity in the control.
How can I do this?
Thanks in advance.

I have a MDI container, inside of it I have a child form that is maximized. If I have a second form created and displayed by the first form that is maximized (with its MdiParent property set properly) the second form will also be maximized. Is there anyway to override this behavior? I know I can use ShowDialog, but I don't want it to be a dialog I want it to be a normal, nonmaximized window. The property on the form is set to Normal and I event do a WindowState = FormWindowState.Normal in the constructor, but it still comes as maximized.
Any suggestions?

No. All the MDI child forms are treated the same. If one is maximized, they all are. If one is "normal", they all are.

Disappointing 
Thank you for the reply though, I guess I will try and make something work with ShowDialog().

My scenario is:
Based on Remoting concept, Server is listening to client on particular port using TCPChannel. Suddenly Server (Listner) went off, which client does not have information. When client sends a message, error is thrown saying "No connection could be made because the target machine actively refused it".
Is there any way to re-establish client - server connection?
Here Server is using randomly selected ports, so we can't hardcode port at client.
Client is getting information of port from configuration file created at user's local directory.
Thanks

From my experience, you only get the exception if you try to call a remote method while the server is down. As soon as the remoting server is running again, all remoting method calls work as if the server was there all the time.
If you say that the server is using randomly selected ports, how do your clients connect to the remoting server?
You have to give a URI for the remoting server object and part of it is the port, so how can this be "randomly selected"?

hello everybody,
I have set some text as labels used in windows app, then I have set the Cursor one bye one for their respective input. Now I want to set fixed width for their fixed input size, as user cannot enter more text as much allow for that. I want also to change the BackGroundColor for their fixed input area.
Please help me.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Just use Console.ReadKey in a while loop, and keep track of how many keys they have entered (or keep track of the cursor position). The code would be similar to the following:
ConsoleKeyInfo cki;
string str = string.Empty;
do {
cki = Console.ReadKey(true);
switch (cki.Key) {
case ConsoleKey.LeftArrow:
--Console.CursorLeft;
break;
case ConsoleKey.RightArrow:
++Console.CursorLeft;
break;
case ConsoleKey.UpArrow:
goto case ConsoleKey.Home;
case ConsoleKey.DownArrow:
goto case ConsoleKey.End;
case ConsoleKey.Home:
Console.CursorLeft = 0;
break;
case ConsoleKey.End:
Console.CursorLeft = 20;
break;
default:
if (IsPrintable(cki.Key)) {
str.PadRight(Console.CursorLeft - str.Length + 1, ' ');
str[Console.CursorLeft] = cki.KeyChar;
Console.Write(cki.KeyChar);
}
break;
}
if (Console.CursorLeft > 20)
--Console.CursorLeft;
} while (cki.Key != ConsoleKey.Enter);Hope this helps,

fellas been developing a c# battleship game and have did go enuf so far
quick question, when i shot at the grid i write back the coordinates such as 1-1, but this is trying to compare it will the coordinates of the sub(for example) which is 1-1,2-1, but i tseems to trying to compare againest the entire coordinates how would i extract the 1-1 or the 2-1??
the cooridnates can go past 10 meaning it cant be a set number
any help please?
thanks

Take Chris's advice from your previous post... make a 2-dimensional array of type bool, then just check to see if that bool is true to see if there is a ship at that location. If you are dead set on doing it with strings, then you should use the string.Split(',') method, then see if the resulting collection contains the string 1-1. Conversely, you could use the string.Contains("1-1") method as well (I think the second is a method, but I am not certain). Hope this helps,

Hello, This is the sample code i have prepired for you now.
public void fnCutText()
{ //Code By Dipak (dipak.dipak@gmail.com)
String strMyString = "abcd,efgh,ijkl,mnop,qrst";
String strTemp = "";
String[] strStrings = new String[100]; int i;
for (i = 0; strMyString.Length > 0; i++)
{
if (strMyString.Contains(","))
{
strTemp = strMyString.Substring(0, strMyString.IndexOf(","));
strStrings[i] = strTemp;
strMyString = strMyString.Substring(strMyString.IndexOf(",") + 1);
}
else
{
strStrings[i] = strMyString;
strMyString = "";
}
}
}
I think u can continue your work.
Best of Luck. 
Good Night.

Use string.split(",".tochararray())

I have this app that sometimes when a user logs in,it will tell the user that the method cannot be called on null values.But when I restart the IIS and still log in with the same name and password,the app will accept.And it will run again for sometime and again it will be giving the same error that method cannot be called on null values.But each time I restart the IIS on the server,the error will disappear.Please do anybody have any clue why this is like this?

Hi,
I'm really stuck here. I'm using reflection to perform an action of all fields that implement a certain interface in a class.
For normal fields, this works fine, but some of the members are generic Dictionary classes in which the content to perform an action on is in the TValue part. Somehow I need to extract that data from the dictionary.
I've been staring at MSDN pages for a few hours now and trying all sorts of things, help would be very much appreciated.
Here's the piece of code.
private void BindToComdriver(ABaseData target)
{
FieldInfo[] fields = target.GetType().GetFields(System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);
foreach (FieldInfo field in fields)
{
Type[] interfaces = field.FieldType.GetInterfaces();
if (t == typeof(ICollection) || t is ICollection)
{
ICollection col = field.GetValue(target) as ICollection;
object[] oma = new object[col.Count];
col.CopyTo(oma, 0);
Type generic_type = field.FieldType.GetGenericTypeDefinition();
foreach (object m in oma)
{
if (generic_type.GetGenericArguments().Length > 1)
{
}
}
}
if(t == typeof(IBindable) || t is IBindable)
{
Bind(field.GetValue(target));
}
}</tkey,>
Standards are great! Everybody should have one!

foreach(Type var in genericarguments)
{
if(var.GetInterface("name",true) != null)
//do actions...
}
I think, but not sure...

Thanks for the reply. Unfortunately that's not working... Any ideas on how to extract the instance value of TValue?

I need ideas for scaling down an image. I tried Image.GetThumbnailImage(), I am able to scale it down, but it lost the clarity. So is there any efficient method to scale the image without loosing clarity ?
