MSDN would tell that. Read about PictureBox class.

You're obviously an utter moron. You really think that's the way to talk to people ? If you're incapable of reading the most basic documentation, then what you got is the sort of answer you deserve, and you should not pretend to have any aptitude for any sort of job that requires intelligence, programming included.

that is not going to be easy. The solution probably contains complex statements such as:

Then why are you doing this instead of something more straightforward ? It looks like you're using a third party component to do this. Where is it not working ?

Sounds like basic maths to me. Is it homework ? What have you tried ?

what did you try? where did you stuck?
please be specific with your questions, so that it will be easy to get answers...
AFAIK, avg = sum / no_of_items;
was this your question???

There is an ActiveX dll in C++ that has some function:
void function(unsigned char* buffer, unsigned long* size);
I added its reference in C# project from COM components tab.
However in C# function it is defined as
void function(out byte buffer, out uint size);
The dll just writes to buffer some bytes array of specific size.
How can we pass that allocated byte[] array to C# implementation?

Hi,
I'm not sure it works the same for ActiveX, however using P/Invoke to call a native code function I would use:
- either the pointer to a pinned byte array (for binary data);
- or a StringBuilder with a sufficient capacity (for ANSI or Unicode text).
Here are two ways to handle an array (example uses int array, similar for byte[]):
unsafe public int ArrayFixed() {
int dim=1000;
int[] numbers=new int[dim];
...
int sum;
fixed (int* pNumbers=&numbers[0]) {
sum=SumArray(pNumbers, dim);
}
return sum;
}
[DllImport("native.dll")]
unsafe public static extern int SumArray(int* pNumbers, int count);
and
public int ArrayHandle() {
int dim=10000;
int[] numbers=new int[dim];
...
GCHandle handle=GCHandle.Alloc(numbers, GCHandleType.Pinned);
int sum=SumArray(handle.AddrOfPinnedObject(), dim);
handle.Free();
return sum;
}
[DllImport("nativeC.dll")]
public static extern int SumArray(IntPtr pNumbers, int count);
Note: no out keyword is used for arrays.

Hello.
What is the use of COM registered component? If you can not use them as a reference module added to the project?
The definition of the function in metadata is different than in C++. It takes just 1 byte instead of bytes array.
Is that just the programmers failure or there is a way to pass to out byte buffer a byte[] array??

if it is just one byte then out byte buffer would be fine, but then buffer isn't the best name for it.

Hi All,
Please tell me how to write XML query in Asp.net.
I hav temple.xml file which contain data of temple.
now i want to apply search on it.
|
|
|
|
|
Load the XML file into XmlDocument instance and write XPath[^] query.
Best wishes,
Navaneeth

The ASP.NET part is irrelevant. You want to use C#. So, what version of C# do you have ? That will determine if you want to use LINQ or if you need to use the XMLDocument class.

public class MyClass
{
private string _MyProperty = "the property";
[colName="theColumn"]
public string MyProperty
{
get { return _MyProperty; }
set { _MyProperty = value; }
}
public string GetName()
{
// code to implement
}
}
public class MyClassTest
{
MyClass c=new MyClass();
// I want to get the attribute in the following way:
string colName= c.MyProperty.GetName();
//colName should be theColumn
}
any kind of help would be appriciated.
and it should be in .NET 2.0 framework

Why do you want to do this ?
The value is going to exist at the class level, you can't change attributes for class instances AFAIK. They are used to specify things for all instances of a class.

I want to do this for the following scenarios:
say I want to Get an object into database.
And I need the column name for WHERE clause
e.g
// Get employees
Get method is like as follows
EmpDA.Get(string filterExpression)
{
//------- the code
}
Employee emp=DAEmp.GetByID(7);
emp.Salary=20000;
EmpDA.Get(string.format("{0}>{1}",emp.Salary.GetFieldName,emp.Salary);
please look at the following factors.
1) I am getting emp list using where clause as "Salary> 20000"
2) But I want to Get the column name "Salary" using emp.Salary.GetFieldName()
thanks for your reply

As Graus said, i too dont find its a better solution for this problem!
but still, you can get the custom attribute values by the following statement.
colNameAttribute mAttribInstance = (colNameAttribute)c.GetType()
.GetCustomAttributes(typeof(colNameAttribute),false).GetValue(0);
The object mAttribInstance will hold the various properties values within your "colName" attribute class. and you can access them by their respective name..
for e.g if "name" is the string used then,
mAttribInstance.Name will give you the value "theColumn"

Thanks King Julien for your reply.
I have already used it when interacting with database for insert update fields
but now my problem is to get the column name "theColumn" in the following fashion.
string colName= emp.Salary.GetColName(); //colName should be "theColumn";
look at the GetColName() after the property Salary. emp.Salary.GetColName();
I am using c# 2.0 framework.

i see...
in that case you may need to create a new class with the function GetColName();
and use it as your return type for property.
example:
Class yourClass
{
public string GetColName()
{
colNameAttribute mAttribInstance = (colNameAttribute)this.GetType().GetCustomAttributes(typeof(colNameAttribute),false).GetValue(0);
return mAttribInstance.Name;
}
}
and u can set the return type of the property salary as yourclass and you will be able to access the GetColName() method!!
Have a Happy Coding.....
