Application Config Suggested Ways Pro And Cons
Apr 6, 2012
I have a general question on app.config, or the best way to NOT hard code a SmtpServer.Host = XXXXXXXX setting. I wrote this very simple SMTP texting application and wanted to have the settings not hard code but a form that read or writes to app.config or .ini or registry. my question is the pros and cons? and if anyone hae suggested or a link to sample project that is doing what I'm after. I have a single .exe and am new to vb.net and either want the exe to check for app.config, ini or registry if does not exist to create and then save added config, if the exe runs again it uses the newly created settings.

I am looking to get some information on updating my own applications. Because what I have to do at the moment is replace the files every time it changes so I would like to know what are the options available starting with the easier ones or does it involve any third party applications. For example I have noticed some applications checks the files before it starts up and then asks a user if he wants to update it

My new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.). The number of DLLs used as references is so huge (almost 50) that when I try to build/debug the application in VS2008, it takes almost 3-4 minutes to get the website running successfully.
Wanted to know if there are any settings/areas which upon some modifications can help me reduce the build time? and what exactly can be the major reasons behind this long loading duration?

I'm Using resharper 6 nighty builds and VB.net. I've a big medium project with multiple files that don't follow the code style conventions of my company.I've configured resharper with my own convenctions and It suggest to me the right name for each variable (perfect!).But I can't find any automagic way to make the current name to be replaced with the suggested name.

Ive created a few in-house applications using Access, such as an IT Ticket tracking database and a database to store legal case logs, but finally found a project that I knew would completely out-grow Access and Im trying to incorporate my previous knowledge in to Visual Basic/Visual Studio.That being said, do any of you have any suggestions for intermediate-level reading material or tutorials, especially on how SQL Server and Visual Studio mix together? I've picked up a copy of Sams Teach Yourself Visual Basic 2005 in 24 Hours, which isn't too bad but I've had to skip around quite a bit because I'm already pretty familiar with the interface, I just need some more assistance with the code. I've also purchased Murach's Visual Basic 2008, but I haven't cracked that one open yet.At any rate, I look forward to talking with you all.

On another programming related website, I saw this line in someone's signature. This is NOT the first time I've seen such sentiments, although this is the harshest:"People who work in VB or any variant thereof are not programmers, they are circus chimps throwing feces into an IDE..."VBA is my bread and butter and I can automate quite a bit of stuff with it. Yes, I know it lacks polish and some functionality, but why so much negativity toward it? On the flip side, what do other languages have that VB doesn't?

i am a seasoned vb6 and vb.net developer and where i currently work, they use VB6. Now, we develop a range of office plugins for a client, and they currently use vb6, they also do some other projects with vb6. I want them to change to vb.net They have asked me for a list of Pros for switching, and also some Cons.
The pros i have are: .Net is future proofed, VB6 will not be supported by Microsoft for much longer One standard platform to run on (.Net) removing problems of windows versions and missing dlls full OOP support and a generic Api for office application development. Integrate seamlessly with Java using bridging components (they are primarily a java house)Quicker performance On event application loading (in office) to help application performance. Application controls are loaded but the code to execute is only loaded when required, reducing application load on start up.Backwards compatible to Office and Outlook 2003

I have been reading up on Abstract classes and am thinking about utilizing them in an upcoming project.
I would like to know the pros and cons of using abstract classes from someone who has actually used them.
Additionally, I would like to know if the abstract class needs to be in it's own project or if they should be defined in an existing project and used within the application.

What are the pros and cons of standardizing on using Option Compare Text vs Option Compare Binary for VB.NET development?
- EDIT -Just some background since it seems like it would help - my development team has found it much easier to standardize on Option Strict On, Option Infer On, and Option Explicit due to their obvious advantages over the alternatives. What we haven't found as easy to standardize on is Option Compare Text/Binary as there seem to be advantages and disadvantages to both and different developers have differing opinions. Some of the arguments for each side have been as follows:
Some of the advantages/arguments for Option Compare Text:
It reduces verbosity in the code by removing the need for StringComparers and .ToLower() calls and StringComparison.OrdinalIgnoreCase all over the place Data needs are rarely concerned with casing, as evidenced by most databases being case-insensitive. Rarely would you ever really want to distinguish between THIS and This and this when doing a data comparison.
Certain specific use cases are simpler when you don't have to worry about casing. For example, handling ASP.NET control events where commands are sent to the codebehind as strings and casing-issues are difficult to track down as the compiler cannot help you. Think Select Case statements for <asp:repeater> events as an example.Many of the concerns raised about text comparison concern internationalization, which is often not that relevant to a lot of applications.VB specifically is case insensitive as a language, though Visual Studio helps you by at least enforcing consistency in your casing. SQL is case insensitive as well. Strings are the only place where you have to remember to worry about it, which highlights the awkwardness in ways you wouldn't normally notice it if you were worried about it everywhere.
Some of the advantages/arguments for Option Compare Binary:C# works this way, as do most other languages. It's somewhat unexpected to have alternate behavior and the unexpected is not good in programming.There is a slight performance penalty with Option Compare Text as evidenced by the IL generated on compile. Option Compare Binary doesn't have that penalty.Option Compare Text only makes certain parts of string handling case insensitive. But, it doesn't make it so that things like dictionary indexing are case insensitive by default. So, it's not like Option Compare Text actually makes it so that you don't have to worry about casing at all. If it only works half way, why bother?Programming is hard. It's best not to attempt to smooth over that fact. Worrying about string casing is part of the deal. Humans recognize THIS is different from This and tHiS. Of course your code should too - after all, they aren't really the exact same string.

Can values from web.config be read completely at runtime or does the application make a copy of the current web.config upon initialization.
Essentially, I'm wandering if I make a change to web.config if it will take effect on the users next postback or if they would need to initialize an entirely new page load. In particular, I'm interested in sections of the web.config like sesssionState and when a change to timeout would take effect.

I've never thought about it before; but I recently learned how I could modify the app.config file to add/remove trace listeners (for example, to redirect all of the Trace.WriteLine output to a text file).But I don't quite understand how it works? I know the corresponding C# code to do the same as the config (in this example) - does that code get generated/executed before my application's entry point?

As a practice exercise at my college we have to make a simple room booking system, complete with its own config file. We're not allowed to use the one built into VB.NET (the professor wants us to adapt to not relying on things like that) so I've made my own. This is a sample:
// Config file.
// First column is the variable name that will be used to
// reference the value in the second column. Seperate each

Well the title says it all im using a asp.net 4.0 project.My file structure looks like this [code]Now the WebService seems to get some parts of the web.config from the RootSite, the problem here is <configuration><system.webServer>..So i tryed to place this around that section <location path="." inheritInChildApplications="false"> but that had the result of making a httpHandler only to function in the root directory.So is there any solution to this? i don't understand why my webservice's web.config is inheriting from the root's web.config..

I have VB.net console application. I would like to read the (ConnectionString) from a web.config.
Web.config is located at a particular path in my virtual PC, say "C:/mywebConfig"
<add name="MY_DB" connectionString="Data Source=DATASOURCE;Initial Catalog=DB;Persist
Security Info=False; User ID=***;Password=****;" providerName="System.Data.SqlClient" />
My code:
Dim connString As String = String.Empty
connString = ConfigurationManager.ConnectionStrings("MY_DB").ConnectionString
Whenever I try to access it, i get the error not set to an instance of an object or something like that :)
I tried to add the web.config in my Project, but still get the error.

I'm trying to use the following command:
Dim xmlFilePath As String = _
System.Configuration.ConfigurationManager.AppSettings("XmlFilePath")
to retrieve the following setting:
<applicationSettings>
<MySolution.WebProject.My.MySettings>
<setting name="XmlFilePath" serializeAs="String">
[Code]....
However, xmlFilePath shows up as Nothing after that line of code is run.
What's the correct code to get a setting out of the web.config file in an ASP.NET application?
NOTE: Although you can add keys individually to the <appsettings> tag, I'm trying to figure out how to use it with the "Settings" tab in the project's properties.

I want to load a dictionary at startup in my console app from my app.config. I know that I could use an xml library or linq to XML to load it to parse and traverse it. My question is there a BUILT IN way of doing it. Isn't there some way to add an application configuration section into the app.config and then have it loaded automagically using ConfigurationManager class in the System.Configuration namespace?

I've just moved an external dll into a folder different from the main exe directory, so I had to use the <probing> command in an app.config file. Now however, the application won't find the dll unless I have the app.config file in the same directory as the main exe! So how can I embed the app.config file in the EXE, or alternatively move it to the folder called 'Resources' where I store the external

I have been searching and posting regarding this problem and have found nothing to aid me. Discussion is either on web.config files or deal only with external files for connection strings or earlier versions of vb.net not 2008.I have already successfully put connection strings into an external config file, but trying the same approach with application settings has failed.There are two sections of the app.config involved with application settings.
1. the configuration and config sections at the top of the config. file where the section group and the section name are described.
2. the actually data for the application settings by section group section name which appears in the body of the configuraton section of the app.config.[code]
