Difference Between C#.Net And .Net?

Apr 27, 2012

know the difference between C#.Net and VB.Net. I use C#.Net for my projects, but when ever I met with some other programmers they often called VB.Net more powerful and easy, than C#.Net. I always asked them "Why it is more powerful then C#, since it uses the same framework?" but still I didn't get any answers.

Difference Between COM And DLL?

Mar 1, 2006

what exactly distinguishes a COM component from a DLL? Isn't a COM component just a library of functions that can be called from another application? Why is using a COM component so much more complicated than just registering it like one would do with a DLL?

C# - Difference Between An Exe An Dll From .net Standpoint?

Sep 26, 2009

I have in the past used .net executables as libraries. I'd just add them to the references in visual studio and I was ready to go. Today I tried the same to a new exe (actually mine) and it doesn't seem to work. When I add it to Visual Studio and try to watch its members on the Object Browser, it doesn't show up anything inside that executable's assembly.

I know the main difference between an exe and dll is that the first has an entry point while the 2nd doesn't. Are there any more differences? I know that unmanaged dll's also have a DLL entry point, do .net have one too?Also, what might be the reasons that could make my standard exe/dll (with this i mean, not obfuscated or anything extreme like that) not show up anything in the Object Browser?

Difference Between 2 Dates

Feb 28, 2012

I am trying to find the difference between two dates. The first of the two dates can be changed and when it is changed, the difference between the original dates has to be retained. This means that I have to automatically change the second date to have the same difference in days as it did before, but with a new first date. [code]I have the value of the old date1(currDate) and the new date1 value(newDate). I need to get the difference between these, and then add or minus these days from the endDate.

Difference Between Instr And Contains?

Dec 8, 2009

for determining whether a string of data contains certain text, which is more efficient? I have read elsewhere that there is somewhat of a consensus to avoid legacy functions, since they may or may not be available in future versions.However, trying to use the contains method (or indexof equivalent of Instr) is causing me problems, I think, because I am having trouble performing a case-insensitive search.

I am trying to be efficient and functional in my code. I am reading an INI file, and I have preloaded the contents of the file into a String variable, for 2 reasons. 1) If I can test if a certain section exists in the code, I can avoid attempting to read a section of empty data (the INI reader class I have chosen returns the value or an empty string for a given request). More importantly, 2) I have created a data field that is not INI compliant (at least not to the API?) as it is a data field that can contain an arbitrary (unlimited?) amount of data which is a hex-encoded representation of serialized byte data. I need to be able to determine if this value exists in the file and retrieve it using normal string manipulation, since the INI handler will not pass strings longer than 256Chr.

So, the problem I am having is getting "strFileContents.Contains("data=")" to return true in the case where the file contains "Data=". This could be data=, DATA=, DaTa=, etc.Instr has the option "CompareMethod.Text" which, I believe, does a case insensitive text search. What is the equivalent for "Contains"?

Difference Between Namespaces In .NET And C#?

Dec 12, 2009

In C#, if you do this, it will compile:

namespace Name
public class Test


I get (depending on the way I try to use "Test") either "'Name' is not a member of '<Default>'." or "Type 'Name.Test' is not defined." in my error list. I've found two ways to make it work, but neither are reasonable to expect of a user. One is to remove the "Root Namespace" from the project properties. The other is to include that namespace between "Global" and "Name".

I have made a custom tool that uses CodeDom to generate code for both C# and VB.NET. This is the reason why neither of the two fixes above are feasible: I can't expect my users to have an empty root namespace, and I'd hate to have to do VB-specific tricks in my code generation (kind of defeats the purpose of using a language-neutral tool, doesn't it?) such as picking out the "Root Namespace" (not that I'd know how off the top of my head) and including it in my code generation.

I don't want to leave out the global modifier either, because it protects the tool from users picking bad names for the generated output. Does anybody have a suggestion for how I should deal with this?

Difference Between Procedural And OOP?

May 17, 2010

I have and still do program principally in a procedural manner. I've never created objects or ever used the OOP paradigm. I understand the concept certainly, and know generally how it works but have never implemented it. I presume this leaves me though with limited options in the future as OOP is and has been all the rage, especially now that VB.Net is full OOP. Event still, I've written both ASP.Net and VB.Net applications without using OOP, or not that the product didn't create itself.It appears I am not alone either, there seems to be a number of people far more intelligent and experienced than I that eschew OOP.

Difference Between The Following Syntax?

Jun 16, 2010

Is there any differnce between the following syntax? Im thinking that there isnt, as long as the end result of the "AS" portion has RuleType named "AS R.RuleType." Notice that the first snippet of code has the R.RuleType and the second has just Rule.Type.strRule.Append(

"select R.Ruleid,R.RuleNumber,isnull(C.ClientName,'') as ClientName,R.Customerid,Case R.RuleType when 'R' then 'P' when 'B' then 'G' else R.RuleType End as R.RuleType,isnull(C.InternalClientID,'')
