I would suspect you can get the info though WMI. Using WMI from C# is fairly simple - you should be able to get a sample from Google. I would probably try to split the search into two:

1) How to use WMI from C#
2) How to get the free memory though WMI (in any language)

just in case you can't easily find an example getting the free memory from C#.

Yes, lmoelleb (is that ur name) is right.
Using WMI in C# you can get Free Physical Memory.

ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem");
ManagementObjectCollection queryCollection1 = query.Get();
foreach(ManagementObject mo in queryCollection1 )
{
Console.WriteLine("Free Physical Memory : " + mo["freephysicalmemory"].ToString());
}

Got it now!:->

Here is what I'm using now:

[StructLayout(LayoutKind.Sequential)]
class MEMORYSTATUS
{
    public IntPtr dwLength;
    public IntPtr dwMemoryLoad;
    public IntPtr dwTotalPhys;
    public IntPtr dwAvailPhys;
    public IntPtr dwTotalPageFile;
    public IntPtr dwAvailPageFile;
    public IntPtr dwTotalVirtual;
    public IntPtr dwAvailVirtual;
}

[DllImport("kernel32.dll", CharSet = CharSet.Unicode,CallingConvention = CallingConvention.Winapi, EntryPoint = "GlobalMemoryStatus")]
private static extern void GlobalMemoryStatus([In,MarshalAs(UnmanagedType.LPStruct)]MEMORYSTATUS lpBuffer);

Maybe somebody needs it.

Thanks for the replies.

Please check the account under which the service is running. By default windows applications runs under the currently logged on user's credentilas who is mostly having all access. But when you run windows service there are different account under which you can run the service.

replacing a string that has double quotes to single qoutes

Hello,

I have some strings which I want to replace them with single quotes so that I can use them as arguments that are passed to a sql query.

Example, string variable Name:
"Peter John"

Should be replaced with single quotes
'Peter John'

so name should contain only 'Peter John'

Is there any possible way to do this.

Many thanks,

Steve

Hello,

I have tried that already. The replace method has 2 overloaded methods. One that accepts unicode, and the other that accepts strings.

I did this:
name.replace(39,34) unicodes for " and '. didn't do anything.

name.replace(" " ", " ' ") accepts the single quote, but has syntax for the first argument.

Any ideas on the above,

Thanks very much,

Steve

lets say we have a string variable that is called name and has in it the name that you want to use:

<br />
String name;<br />
name = name.Replace('\"', '\'');<br />

Note: \ is the escape character

Hello,

Thanks for the reply,

However, I used your method, but got an syntax error "Expression Expected"
Sorry for the confussion, but I should have posted this in the VB.Net forum. I thought i did.

I tried you code in C# and no syntax error, but still did not replace the double qoutes. When I put the mouse on name in debug mode after replace, it still have the double quotes.

code in c#,

<br />
string name = "Peter John";<br />
<br />
            name.Replace('\"', '\'');<br />
<br />
            MessageBox.Show(name);<br />

What am I doing wrong?

Thanks for your help,

Steve

Compare the code that you have with the code that quiteSmart posted. What have you removed?

Strings are immutable in .NET. That means that a value of a string can never be changed. To get a different string value you create a new string. That gives that the Replace method does not change the string that it's used on, instead it returns the new string.

string test = "\"Peter John\"";
Console.WriteLine(test);
string test1 = test.Replace('\"', '\'');
Console.WriteLine(test1);

Hai,
See the code below:

name="\"Peter John\"";

string SqlQuery = "Select * from employees where EmpName=" + name.Replace('\"', '\'') ;

This will give you the SqlQuery string value as "Select * from employees where EmpName='Peter John'"
Hope this will be useful..
Plz try this...

hi,

first NITIN_098 is right. You should use checkboxes and going into radio buttons and group boxes.

Anyways if you chose to use the radio buttons you can implement it ot unselect on check using the on-click event. Put a certain confition in it and say if the radio button is checked uncheck and if not checked then check.

good luck

Grouped radio buttons are used to make a single selection. Use Checkbox instead.

What’s the difference between the System.Array.CopyTo() and System.Array.Clone()?

Re: difference between

rah_sin4-Dec-06 19:28

rah_sin

4-Dec-06 19:28

i think System.Array.CopyTo() is used to add array elements to another existing
array object from the index which we specify onwards where as System.Array.Clone() is used to create similar array object with same elements

rahul

Re: difference between

Bhupi Bhai4-Dec-06 20:25

The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array.
The CopyTo() method copies the elements into another existing array. Both perform a shallow copy.
A shallow copy means the contents (each array element) contains references to the same object as the elements in the original array.
A deep copy (which neither of these methods performs) would create a new instance of each element's object, resulting in a different, yet identacle object.

Bhupi Bhai.
