In vb, if wanted an easy way to convert from one of my classes to another custom class, i can define the CType operator to define how to convert from one class to the other. I can then call CType( fromObject, toNewType) to do the conversion or in c# i guess you can just do a simple cast.
However, in c# how do you define how the actual cast will be handled from one custom class to another to another custom class (like you can in vb using the CType operator).
I am trying to build a windows application that will automate a regular routine steps that I have to do for taking a backup.The flow goes like this...1.open a folder2.run an exe there3.open jumpbox server at which point we have to enter a username and password4.create a folder5.then open a network folder using the ip suc
I have a multi-project .NET 3.5 solution. It's ASP.NET based with c# code-behind in all projects except one.I'm attempting to access members from a C# project called "Core" from a VB.NET project. I set a dependency to the Core solution in my solution properties. However, Core. brings up nothing. Furthermore, my other C# projects that have Core-Project as a dependency (in the solution settings), are able to declare Core objects. Example: Private Core.ObjectName InstanceName; Also, Intellisense brings up plenty of info in the C# projects.how I can hook into these members from my VB project?
I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic's And and Or in C#?For example, consider the following VB.NET code.The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic's And operator is perfect for this situation, but unfortunately there's no equivalent operator in C# as far as I know (&& short-circuits).
What I am trying to do is to check if a value matches one of two numbers (and easily be able to add to the numbers to compare to). Rather than doing a longer-winded way such as: [Code] I have found that this only works when SectionID is 2 or PageID is 8. If SectionID is 3 or PageID is 12 then it doesn't work. Why is this and what can I do to try to get around the problem?
I'm normally at home in C#, and I'm looking at a performance issue in some VB.Net code -- I want to be able to compare something to the default value for a type (kind like C#'s default keyword).
I am relatively new to Visual Basic. When it comes to logging, in Java I use log4j for logging.What is the equivalent in Visual Basic and can you please guide me to a good tutorial?
I've got a large codebase which I'd like to expose to plugin authors to allow them to use VB.Net Express to code plugins for a server app, which is not available to them. My problem is that even with obfuscation, I'd rather not distribute the complete app and/or dlls, as even with obfuscation peeling apart a .NET assembly and puzzling out code is relatively easy to do. I'm interested in this because the licensor I obtain the code from requires me to protect IP and assets and while distributing .NET apps opens up the app to disassembly, keeping the server app private and allowing users to utilize a skeleton dll to code against is a happy medium.
What I'm looking for is some way or a utility to go through my server app source code and create a codeless version of the app which only contains method and property signatures.The intent is to provide a stub .NET dll for them to add as a reference and code against as if they were directly interacting with the server, without actually providing the server code to them, compiled or not. I can of course do this by hand but there are over 90 classes and hundreds of thousands of lines of code I'd rather not spend a week hand tweaking. Also, this presents a problem whenever new methods or code are added to the project. Finally, two separate projects is an even worse scenario.Because people will post suggestions that have little or nothing to do with the question, here's a short, clear example. I want to turn this class:
Public Class MyServer Public ReadOnly Property Name() As String Get Return "Whatever"
What is the vb.net expression of this c# expression ?
Frame.GetController<ShowNavigationItemController>().CustomShowNavigationItem += new EventHandler<CustomShowNavigationItemEventArgs>(WindowController1_CustomShowNavigationItem);
I'm looking at some old ASP code that contains the following:
Set objDSE = GetObject("LDAP://RootDSE") Set objSysInfo = CreateObject("adsysteminfo") Set objUser= Getobject("LDAP://" & Replace(objSysInfo.UserName,"/","/")) dtmValue = objUser.PasswordLastChanged
[code]....
This is for an intranet app that uses integrated authentication. Is there a replacement for the ASP adsysteinfo object? I can probably port most of the LDAP calls using System.DirectoryServices.DirectoryEntry, but is there a better/easier way to do this in ASP.NET (VB.Net or C#)? how to convert the ASP object properties to DirectoryEntry properties?
I have made an application in vb6 abd now trying to do the same in visual studio 2005. In vb6 i was using MSFlexgrid and its .Textmatrix properties. Would like to know what is the .Texmatrix equivalent for .net. When i pasted the code form vb6 i get the following error...
'TextMatrix' is not a member of 'AxMSFlexGridLib.AxMSFlexGrid'

Does C# have an equivalent to VB.Net's DirectCast?I am aware that it has () casts and the 'as' keyword, but those line up to CType and TryCast.To be clear, these keywords do the following;CType/() casts: If it is already the correct type, cast it, otherwise look for a type converter and invoke it. If no type converter is found, throw an InvalidCastException.
TryCast/"as" keyword: If it is the correct type, cast it, otherwise return null.DirectCast: If it is the correct type, cast it, otherwise throw an InvalidCastException.
EDIT: After I have spelled out the above, some people have still responded that () is equivalent, so I will expand further upon why this is not true.
DirectCast only allows for either Narrowing or Widening conversions on inheritance tree, it does not support conversions across different branches like () does.ie: C#, this compiles and runs:
//This code uses a type converter to go across an inheritance tree double d = 10; int i = (int)d;
i didn't want to trust this one to any number of online conversion websites that I often use.I don't need to convert the declarations, just the expression '(byte)((flen & 0xff00) >> 8)'in

As I understand it Context menus are meant to replace the Popupmenu command as we knew it in VB6. This is fine if the menus are different than the existing main menu.Do I really have to re-create portions of the main menu for my context menus or can I somehow get the context menu to point to the main menu strip branch of my choice? (As in VB6.)
In vb 6.0 when receiving data over a socket connection you used an event called dataarrival (winsock1.dataarival) to handle incoming data and process it. Is there an equivalent process in .net? i am unable to find it.
Currently, I am enclosing object initialization and usage in a Try/Catch block and then tear it down (dispose, close, set to nothing) in the Finally block. The problem is, a C# 'using' block is so easy to use and would clean things up in my code.
Is there a VB.NET equivalent? Or is my Finally block tear-down solution the only way?
