Hello
I had a question about named delegates. Now from my understanding named delegates can only hold references of a method that matches the signature of the delegate. I have a piece of code which is contrary to this statement.
Using System;
delegate int CountIt(int end);
class varCapture{
static CountIt counter()
{
int sum = 0;
CountIt ctObj = delegate(int end) {
for( int i = 0; i <= end; i++ )
{
Console.WriteLine(i);
sum += i;
}
return sum;
};
return ctObj;
}
public static void Main()
{
CountIt count = counter();
int result;
result = count(3);
}
Now the delegate of type CountIt must refer to a method that takes int as a parameter and returns int as a parameter.
CountIt count = counter();
In the following line the delegate count is pointing to the method with no parameters or return type. So I wanted to understand how is it possible?
Is this assignment possible because the counter() is returning a object of type CountIt(same as that of the delegate)? If so when CountIt count = counter(); is executed it calls counter() and then just initializes the CountIt object an return it, does it actually go into the anonymous method block code? If not why?
Thanks

int MyMethod()
{
return 9;
}
int n = MyMethod();
That's all your code is doing, it's no mystery.

counter() returns an object, which is a delegate. So, this works. When the delegate fires, it will run the anonymous code, because that's how the delegate was defined.
The code is convoluted, but it's correct.

I'm using a Type Library Importer (Tlbimp.exe) for converting Microsoft PowerPoint 12.0 Object Library(Office 2007) to an Interop dll. If the same dll is used in the system where Lower versions Microsoft PowerPoint(Office 2003) is installed. I'm facing an error
The Command used to convert into the dll.
TlbImp "C:\Program Files\Microsoft Office\OFFICE12\MSPPT.OLB" /keyfile:"C:\32\DotnetSigning\Signature.snk" /namespace:Interop.PowerPoint12 /out:"C:\New Folder\Interop.Office12.dll"
If i refer the dll in my C# .NET application. I'm facing with the below error;
"Assembly 'Interop.PowerPoint12, Version=2.9.0.0, Culture=neutral, PublicKeyToken=4316ebe69d6f1d49' uses 'office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' which has a higher version than referenced assembly 'office, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'"
Is there a work around for this error?
Thanks in advance,

Does anyone knows about good free UI library or even collection of good UI Controls for vs 2005 ???
|
|
|
|
|
System.Windows.Forms :P
On a more serious note you'll generally have to pay for a good collection, if it's only a few specific controls your after then you might be able to search around until you find free versions of each of them.

Maybe yes, I'm not in the position to say so!
But I think it's not the reason for his rude double post.
He is a member since 1year and 8monthm, with over 130 posts on the forums.
So he is well experienced and did it on purpose I think.
All the best,
Martin

Hi,
There are two way to read the file.
1) Use the network path of the file to read at the local PC. The network path will be somthing like \\remotePCName\\folderName\\FileName.ext. But for this the file/folder needs to be shared on the network PC.
2) Write a Client/Server application. You can use Remoting or Socket for this purpose. Your Server should implement a interface with a function to accept the file name with path and will return the file contain as out parameter. In this case you needs to run the server at the remote PC and it must me running while you will read file containt from the client program.
