Asp.net - Find A Clean API For VB Development?
Feb 18, 2010
I am completely new to ASP.NET programming, and was asked to work on a small project involving ASP.NET, VB (which I am new to as well) and Microsoft SQL Server 2005.Being used to php/java I was hoping to find some kind of similar API to php.net and the javadoc. It would be very useful to have as I would prefer to work with a text editor, instead of using DreamWeaver or Visual Web Developer.In the project I basically only need to use ASP.NET to read from a SQL 2005 database and write to JSON files. where to find a clean and decent API to work with?

I'm a Coldfusion Web Developer and I'm finding that in my local area, work for CF Devs has become extremely scarce.There were a handful of companies that were Coldfusion houses a few years ago and it appears most of them have moved away from CF development.I'm looking to expand my skillset to improve my employment outlook, and it appears that many of the web development positions that are available to me now are focused around .NET web development.The last time i took a look at .NET as a web development platform was way back during 2.0; where I found it to be poorly organized and extremely unfocused. Apparently somewhere along the line I missed the boat because that's where about 90% of the web development jobs in my area are now. I've done some searching on google to see if I can find a tutorial, something that's akin to hand-holding, and have come back dissapointed.So I'm turning to the SO community to ask for links and resources that might help better explain how .NET development works in a web development capacity, and for links to these resources so I can begin boning up my knowledge and start writing practice applications.

[code] If there is an error inside the Using block how do you clean up the sr object? The sr object is not in scope in ErrHandler so sr.Close() cannot be called. Does the Using block cleanup any resources automatically even if there is an error?

How to clean up a string in Visual Basic .NET? I'm creating a string as a report with line breaks. However, the string is built based off of screen scrapes from a TN3270 emulator. The string is saved successfully with all of the data I require, but those annoying rectangle symbols show up once I send it to a notepad text file. Do you know anyway I can strip those out and clean up the output?

I need to simply identify if a particular tag occurs in an XML document. At this point my XML solutions, much like my regex solutions, are based on limited knowledge and are far from elegant. Is there a better way to achieve the following:
For Each e As System.Xml.XmlElement In xmldoc.GetElementsByTagName("stat")
parse = False

I'm currently making my first program, its an active directory clean up tool. Right now I'm having diffculty getting it to search sub OUs that it sees, I can get it to look at one layer of the sub OUs. I just want more of a dynamic code so I don't have to keep repeating it like I did do. Also I'm not sure that I'm looking through active directory the best way.

I need to get strresult to give me a clean string with no punctuation from strinput. I wanted to store that in strresult. My main goal was to write a loop to check the textbox input - strinput for letters a-z and store them in strresult and compare the reverse of that to strinput. I can do codes like mom, and things like that and it reads them, but when i add characters like mom! and red rum, sir, is murder...I am not stripping the punctuation off correctly.

My app is basically talking to a device via RS232. I need to 'listen' to the data received and do certain things based on it, update labels, etc. When I started, I only had a couple cross-thread calls and I used JMC's example to get by that. Now my app is bigger and I am calling the ThreadProcSafe all the time. I am hoping there is an easier way so I don't have to create sub routines for every control. Here's the relevant parts of my code.
Private Sub StepperSerialPort_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles StepperSerialPort.DataReceived
Dim ReceiveBuffer As String

I've created an app, which puts windows onto the desktop. When i click on the window it creates a new window and passes the first window's Items collection to the second window's Items collection. Opening the second window adds around 2-4 megs of memory to the app's mem usage. Now if i close the second window, the memory still stays on the same level as when the window was opened. When closing the window, i reset the Items property and clear all images that i'm using in it. It has a wrappanel with some elements, that's also cleared using the .clear function of the wrappanel.children. What else should i do to free up the memory?

I have a table in a Access Database that I'm loading into a VB.NET program and I want a way to get the name of each of the columns into a list of Strings. Googling has shown that this is much easier with a SQL database, but that doing so in Access is much more difficult. I came across this question Is there a query that will return all of the column names in a Microsoft Access table? Which gives a way to do it, but when I try the code it just populates my list with a bunch of "System.Collections.Generic.List'1[System.String]"
This is my adapted code.
Public Function GetColumns(ByRef database As String, ByRef table_name As String, ByRef columns As List(Of String)) As Integer
Dim com As OleDbConnection
Try
com = New OleDbConnection(database)
com.Open()

I am trying to create a string1 in My.Settings and used the My.Settings.Save method and it is working perfect. The problem is that the default value is "My Name is X" and the given saved value at runtime is "My Name is Z", when the next time I run the debugger in VS2010 with F5 key i am getting the new value only not the original x, I tried to clean, rebuild the app but still the new value is only showing up, how to debug with original values

I've noticed something in vb that is rather disconcerting, and now i'm trying to find if there is a way around id. Given the nature of enumerated types, they are more or less substitutes for named values, usually grouped in some sensible manner for readability as well as other things. Now, .Net added the FlagsAttribute() for affecting a Enumerated type so that it can reference multiple values (bit flags) for additional support. (Basically it is easier to say If MyEnum And MyFlag as opposed to if MyNum and 65536) However, sometimes we just want to cycle through our enumerated values For x = 0 to N Next I've noticed that with Enumerated types, it is ever so annoying in two folds:
A) Dim X as MyEnumType = 8 '<- Causes a Type Error : Cannot implicitly convert Integer to MyEnumType
B)
For X as MyEnum = MyEnum.Lowest to MyEnum.Highest
Console.Writeline(Ctype(x, integer))
Next
[code]....
However, as per usual, VB cheats, and performs the latter (violating VB's own Strict Typing rules) and thus if I have 8 enumerated values, each representing a Bit value from 1 to 256, How can I smoothly (with not extraneous executions) run the loop from lowest to highest. (now of course this is bitwise, so i could do a while loop with a << operator, but let us just assume we don't know the values of all the Enumerated elements, we just know they aren't sequential (+1)). I want a loop that ONLY executes the ACTUAL elements of an enumerated type, nothing in between their intrinsic values.
