Well one solution is to change the namespace to match the namespace of your project. There might be a better one out there but that should do it.

That may do it, but I want to be able to use this library for multiple projects. I thought that was the idea behind object oriented programming. Building parts..

I added the Class Library by using the "Add Existing Item" from the Project menu and selected MyString.cs.
If you want to add reference to your Class library use "Add Reference" from Project Menu. Then if your class MyString is in namespace MyNamespace you can use it in another project like this:
using MyNamespace;
MyString str=new Mystring();
string s=MyString.NumericOnly("1234a");
or
MyNamespace.MyString str=new MyNamespace.Mystring();
string s=MyNamespace.MyString.NumericOnly("1234a");
In your code you are not using MyString namespace so compiler thinks that MyString is namespace and not class as you wanted.
Hope this will help

Hi...I'm trying to call an API, which takes a pointer to a structure that contains unions. I'm not sure how to build this in C#. Where I'm having difficulty is what to do for the unions and how setting a length for the character array. I know I'm going to have to use UNSAFE code for the dereferenced pointer.
I have enclosed the subset of the structure below...
typedef struct CCVUSER
{
SHORT TransactionType;
SHORT ProcessingMode;
PVOID pvBatch;
UCHAR uchErrorText1[255];
UCHAR uchErrorText2[255];
UCHAR uchSettingsPath[255];
union CCV
{
struct CreditCard
{
CHAR *CardInfo;
CHAR TransactionDate[4];
CHAR InvoiceNumber[10];
double CashBackAmount;
double TipAmount;
double Amount;
BYTE CustomerPresentFlag;
} CreditCard;
struct CheckApprovalRequest
{
CHAR IDType[2];
CHAR Number[26];
CHAR DateofBirth[6];
double Amount;
CHAR CheckSequenceNum[4];
} CheckApprovalRequest;
} CCV;
} CCVUSER;
Thanks for your help...

Here is a C style union in Csharp.
Out of the best Book I have read so far for .Net.
Essential .Net Volume 1.
[StructLayout( LayoutKind.Explicit )]
public struct Number
{
private enum NumType
{
Double,
Int64
}
[FieldOffset( 0 )]
double dblValue;
[FieldOffset( 0 )]
long lngValue;
[FieldOffset( 8 )]
NumType type;
public void Set( double value )
{
type = NumType.Double;
dblValue = value;
}
public void Set( long value )
{
type = NumType.Int64;
lngValue = value;
}
public double GetDouble()
{
if ( type == NumType.Double )
{
return dblValue;
}
return (double)lngValue;
}
public long GetLong()
{
if ( type == NumType.Int64 )
{
return lngValue;
}
return (long)dblValue;
}
}
Thank You

Hello.
If a function like OnMouseMove is implemented in a derived class, without any message map info, this function gets called when the event occurs. How is the housekeeping done on this? One would think there is an overhead of calling all the event functions irrespective of wether it is implemented or not. Or is an optimization done at compile time?
Any useful links or explanations on this would be helpful.
Thanks in advance.
Regards,
Priyesh

Event handlers are basically a linkedlist of function pointers. The standard implementation will check whether the event handler is null, otherwise it will invoke each function pointer (delegate) in the eventhandler.

Does this mean that delegates and Onxxx functions use the same mechanism to deliver events?

Hello,
I've set up a site for my company which pulls content links from the database and binds them to a repeater which produces a list of linkbuttons with the text and link to the appropriate story. However, a great deal of importance has been attached to search engine placement and the ability of spiders to travel unimpeded throughout the site. Since a linkbutton does not produce a conventional url which can be followed by a spider, is there any piece of data that a linkbutton can produce allowing a spider to travel to the displayed link?
Thanks for any help you can provide.

I have a question abount Socket Communication.
When Socket Connection was founded with Server and Client,Cliet send information to Server.Whether string array can be sent to Server.In the other hand,Whether object can be sent to Server.
When Server received the information,whether it can be convert to Array,or other object.

Objects have to be serializable (take a look at SerializableAttribute).
Arrays are serializable, if the elements are serializable.
You can send a serializable object/array through a socket by BinaryFormatter.Serialize(). The other side can read it by BinaryFormatter.Deserialize().

I am trying to convert a routine from C to C#, that will scan over a character array converting the 1st character of every word to upper case. I mainly use this on peoples names.
In C it was very simple, I just loop over the characters and "AND"ed the byte with 0x20. In C# it wouldn't let me do that with strings, saying it was read only, so I tried copying it to a byte array, which kinda works.
I removed the 1st letter of each word logic to simplify the code. Now the code reads:
byte[] strout = new byte[255];
string workstr;
workstr = textBox1.Text;
for (int i = 0; i<textbox1.text.length; i++)
{
="" if="" (textbox1.text[i]=""> 0x60)
strout[i] = Convert.ToByte(workstr[i] & 0x20);
else
strout[i] = Convert.ToByte(workstr[i]);
}
textBox1.Text = Convert.ToString(strout);
What I am getting when trying to "AND" the 0x20 is just 0x20, it doesn't just turn off the bit. Also how do you convert the byte array back to a string? I have tried a couple of convert methods but haven't had much luck.
Thanks,
Glenn

When I pasted in the code the for loop got chopped off...its actually like this:
byte[] strout = new byte[255];
string workstr;
workstr = textBox1.Text;
for (int i = 0; i<workstr.length; i++)
{
="" if="" (textbox1.text[i]=""> 0x60)
strout[i] = Convert.ToByte(workstr[i] & 0x20);
else
strout[i] = Convert.ToByte(workstr[i]);
}
textBox1.Text = Convert.ToString(strout);

Firstly, you can still do this with C# - convert the string to a char[] array using String.ToCharArray(), AND each char that needs it, then convert the char array back to a string using new String(chararray). (It's not byte because .NET uses Unicode.)
Secondly, the AND 0x20 isn't needed, as you can use Char.ToUpper().

The simplest solution is to treat the string as a character array instead of a byte array. Here is a simple function that you can pass your line of text to. It simply looks to see if the current character is the first character in the array or if the previous character is a space and capitalizes the character accordingly.
string formatString(string input)
{
char[] result = input.ToCharArray();
for(int i=0; i <= result.Length; i++)
{
if ((i==0) || (result[i-1]==' '))
result[i] = char.ToUpper(result[i]);
}
return new string(result);
}

The i <= input.Length should be i < input.Length.
0 Based.
