Zip Microsoft.Office.Interop.Excel.dll with my application?

Hello. I created an application that automates Excel. It looked like that if the dll "Microsoft.Office.Interop.Excel.dll" was not with my exe, the application crashes on other PC's. Since my application doesn't provide a set-up program (X-copy application), I would like to zip that file with my application. Is that permitted? I tried to research on my own but I couldn't find the answer. I even consult the lawyer in our company but he was not able to give me a clear answer. By the way, that dll came with Visual Studio 2010 (located at C: \Program Files (x86)\Microsoft Visual Studio

Handling backspace in a RichTextBox - again!

Hello, I'm revisiting a problem I've never solved satisfactorily. I have a multi-line RichTextBox that receives text input from a serial port (not the keyboard); that input frequently contains backspace characters. To handle the backspace characters I'm currently calculating the offset of the character to be backspaced over from the beginning of the entire text box, selecting that character, then replacing it with no character. The "for" loop in the code below calculates the length of everything in the text box. While this scheme has worked correctly, it really slows the s

Error: InterfaceDictionary ... does not implement interface member ...

I am attempting to create a custom collection class which implements IDictionary -- with parameters -- public class MyClassCollection : IDictionary <int, MyClass> The purpose for this effort is to learn C# programmer at a slightly deeper level.

Right now -- my collection class can store my custom class objects, and I can retrieve a count of ob

Quick inheritance Q

Use of Assembly Attributes

We have been trying to mimic a sort of "plug-in" design with our app. We are loading assemblies which are in the app's assembly directory and then iterating all the Types in each Assembly to find ones which match the plug-in loaders designated type. I was thinking of perhaps trying to use Assembly Attributes to mark the plugin Assembly(ies) so that we don't bother iterating the types from other assemblies which we know wouldn't contain the "plugin". It seems like there is a Product Info Assembly Attribute, that maybe could be used for this purpose. I'm not totally sure that thi

delegate vs condition check

hello everyone, today i tested the speed of a delegate relaying to a function against the speed of an an if, that checks the condition of a boolean value, relaying to a function (the code is attached at the end of this post). in my test it turned out, the delegate was twice as fast as checking the boolean. this lead me to the conclusion, that whenever object behavior depends on values, known from time of construction, it is faster to compose an object (compose of delegates and/or other objects) at construction time, rather than checking condition(s) every time an object is used.

System.IO.TextReader+SyncTextReader

The statement System.Console.WriteLine( System.Console.In.GetType() ); prints System.IO.TextReader+SyncTextReader under Microsoft� Visual C# 2010 Express. What a kind of type is this?

How to implement IDictionary with <int, MyClass> members for custom Collection Object?

.Net application architecture suggestion...

Hi, We are in the conceptual phase to create a relatively medium size enterprise business product application using Silver light 4.0, Entity Framework and WCF. 1.

If you need any further details do let me know, i will be happy to share. Thanks in advance.

Chossing port for server lsitening
