Convert String Back Into XML?
Aug 3, 2010I'm currently creating a web service that will allow the user to access a staff directory that is stored in an XML document format on a server. What I've managed to do so far is load my XML document into the server, convert the entire contents into a string and send it over SOAP to my client. The client successfully receives the entire content of the string. My problem however is that I'm finding it hard to find a technique that will allow me to convert my string back into an XML structure. I used a messagebox in the client to display the contents to make sure everything is received and all is well. Below is the code I'm using on the server side to convert the XML document to a string.[code]....
View 7 RepliesConvert String To Integer Then Back?
Jun 17, 2009This is my first time posting on the site, but I have found it very helpful in the past. I'm a self taught VB.NET developer and I have run across two questions.1) I'm working on a clients site to add a dynamic billing amount that is determined on what drop down list value is selected or what string gets input into the text box. I'm using nested case statements for this since it seemed a little easier, I'm also using two string arrays to hold my variables for use later on. Here is my question, since I am using strings for my variables do I need to convert them into integers to add them? I know the amp sign "&" is used for combining strings and whatnot, but does the plus sign "+" add the values together or combines them? I know if I convert the string to an integer then convert it back to a string that it will cause more processing to be done and I don't want that. What would be my best option in this case?
2) As for my second question, what's the best way to find an exact string? I have used InStr() before for small checks and it works just fine. But I was wondering if using str.Contains() is better suited for this task. From my understanding, InStr() looks for a relevance of the string you're looking for and str.Contains() looks a little more closely to better find what it is you're looking for. The reason I need to find an exact match is that if the user inputs 10 in the textbox, the code won't give them the price for 1. I have 4, 6, and 8 defined in the drop down list so I'm not worried about those. Would adding pound signs "#" around the string I'm looking for help narrow it down to only what I want?
As for the code, it's not completed. I just started it and began wondering on what was the best way of doing this. Private TUITION_COST As String() = {"900", "1800", "2700", "3600", "4500", "5400", "6300", "7200", "8100", "9000", "9900", "10800"}

Get Enum Given Its Name (convert From C#)?
Oct 14, 2009How do I do this C# statement in VB.Net (2005):MainMap.MapType =(MapType)comboBoxMapType.SelectedValue;MainMap only accepts Types so passing the Integer value of the type is not possible. The combo contains a list of strings:comboBoxMapType.DataSource = Enum.GetValues(typeof(MapType));In my case I need to limit the list to less than 100% of the Enum values so code similar to .Datasource= code will not work.So in general I need a way to return an enum given the name of the enum.Maybe I should just do a Collection of Enums (if that is even possible) and use the name as the Key?

An Integer String In An Enum?
Oct 8, 2010I know this is a proper enum:
Private Enum Months
JANUARY = 1
FEBRUARY = 2
...
End Enum
However, I want to have an enum where the string will solely be integers.
Example:
Private Enum ColumnCounts
01 = 5
02 = 4
03 = 40[code].....
Essentially, I didn't want to put the f in there, just wanted to do 01. The way this will be called is:
Select Case (nRecordType)
Case "01"
...
Case "02"[code].....
Because I'm not making an instance of it and not calling a constructor, there's no way to autopopulate a Dictionary.And I don't want to convert to integer so I'm not going to do an array. That is just in case eventually the value gets above 99 and the next value would be A0.I'm trying to think of easy future changes to this and backwards compatability.If you need more explanations, let me know.
Edit 2:This is what I've done now and I think it should work:
Public Class Part
Private Shared columnCounts As Dictionary(Of String, Integer) = New Dictionary(Of String, Integer)
Public Shared Function ValidateColumns(ByRef lstFiels As List(Of String)) As Boolean[code]....
I can't verify that it's going to do what I want to, but it doesn't give me an error when I build it so I'm crossing my fingers.

Convert .EXE File Into Byte And Back Again ?
Sep 2, 2010Basically what I'm now trying to find out is simply how to convert an Executable file into byte or byte array as i've heard it called, and then back again. I had a friend used to do it with a program in VB6 a few years ago where he would convert the EXE into byte and store it in a sql database and then his boss would be able to retrieve it later on when he was out on business overseas and it seemed to work very well.I'd like to know how to do it in VB.NET, however after going through some sites using google search I have come up short.

Nullable Enum Verse Enum.None?
May 26, 2010Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

Apr 1, 2010This is a related to a previous question I have asked here, see the link below for a brief description as to why I am trying to do this.Regular expression from font to span (size and colour) and back (VB.NET).Basically I need a regex replace function (or if this can be done in pure VB then that's fine) to convert all ul tags in a string to textindent tags, with a different attribute value for the first textindent tag.For example:
<ul>
<li>This is some text</li>
<li>This is some more text</li>[code].....
Basically I want the first ul tag to have no indenting, but all nested ul tags to have an indent of 20.

Converting An Array To A String And Back?
Oct 16, 2009I'm trying to convert a large array to a string, and then back into the array again after sending it over a network connection. No problems with that, but to keep my string as small as possible, I want to convert each array element into a single byte. I know that each element is going to contain a number no bigger than 100, so there will be no problems keeping them all 1 byte long. Problem is, I can't find the correct conversion commands. I think I should use 'Chr' to convert them into a string, but I can't work out how to convert that back into a number at the other end.
View 3 RepliesConverting Hex In A String Back To Bytes?
Jun 9, 2011I've got the following simple code to convert Bytes to a Hex string :-
Code:
Shared Function BytesToHex(ByVal bytes() As Byte) As String
If bytes Is Nothing Then Return ""
Dim S As String = BitConverter.ToString(bytes)
[Code].....
The HexToBytes routine obviously can take a lot longer to complete than the BytesToHex routine and is noticeably slower when dealing with a lot of data. As I'm converting a lot of hex strings back to bytes, I wondered if there was a more efficient way of doing it without looping through the whole string as I am doing?

Connection String And Back Ground Worker
Dec 3, 2008I have an application that monitors a set of opc boolean tags.When a tag changes from false to true (triggered), the application is supposed to query the database for data recording during a specific time period.I had the app done or so i thought until i realized that the background worker that i dimension to do the query is not firing the runworker completed event.at the start of the app, I create a new class for each trigger config in an xml file. Each trigger class has its own opc monitor and handle specific for that one boolean tag.If a tag changes to true a NEW instance of the query class is created.A new background worker instance is dimensioned to do the actual work.(this because there is a pre trigger query and a post trigger query which could be up to 24 hrs after the event has been "triggered" to true and the bg worker will wait until the required amount of time has completed before doing the post query).When the bg worker has completed, it should dispose of itself and all its managed resources.
The very first tag that changes to true will function as expected but when it is complete the RunWorkerCompleted will not fire. Everyone there after will operate as expected but not the very first one.I couldnt figure out why so I started commenting out some code.If I remove the line to create a new oracle connection, it works.
