Asp.net Mvc - Getting String Value When Delimiter Exists?
Oct 18, 2011
I am working on finishing up a mvc 3 vb.net app... I have to parse about 2000 entries in a database and get the string value to the right of a " : " delimiter from one of the columns... Everything to the left I am not worried about but I need the value that is to the right of the colon for that item.. I have more issues involving needing to select string characters to the right or left of a delimiter... But if someone can show me how to achieve the above I can figure out the rest from there...
a example of the string is Jackson Smokehouse Fish Food:John Jacob JinggleHimer Schmit I would want to eliminate the first part of the string or just select the second part and put it in a variable for later processing...

I want to split a string at a delimiter, but I don't want to discard the delimiter; It needs to become its own variable. [code] Is there any way of achieving this short of writing my own method?

lets say I have a string that I want to split based on several characters, like ".", "!", and "?". How do I figure out which one of those characters split my string so I can add that same character back on to the end of the split segments in question?
Dim linePunctuation as Integer = 0
Dim myString As String = "some text. with punctuation! in it?"
For i = 1 To Len(myString)

I have an string that is returned from an xml file and looks similar to this name1="test 1" name2="test2" name3="test 3".I want to split this into 3 elements of key=value. I can't just split using a space because some of my values may contain spaces, e.g., test 1.So, I'd like to split the string using the " before the space. I've tried many variations but can't figure out the correct syntax to specify that my split characters are a " followed by a space. For instance, I've tried text.split({""" "}) but that returns elements split by " and ignores the space after the ".It shouldn't be this difficult. Can someone please help me with the correct syntax?

The Data looks like this:
Quote:
057359-001 Pip Drt329 Auburndale, Fl (aub) - Pompano Beach, Fl (pob) 1:0 10gbe Lan Phy.
MyArr(0) ends up "057359-001" which is correct.
MyArr(1) ends up "Pip" only which is incorrect.

When the user clicks any item in the listbox ie lviproducts it passes that item to a textbox. The problem is that I want everything before the $ sign not to appear so only the amount ie 4.50 etc would appear in the textbox. So far I have no idea how to do this, but have the following code which is not working at all.

What would be the simplest way to find the n-th position of delimiter in a string.For example, say, I have a string variable called FullFilePath that contains the path of a file, like, C:SourceFiles<mthyr><subject><filename>.txt From this, I would like to extract out mthyr, subject, and filename, using the delimiter, "".
I was hoping string.IndexOf would let me find the n-th position of the delimiter "", in which case I can use the result to do a string.Substring. But it looks like IndexOf only finds the first occurence of a certain string, which means I would have to interate this somehow to look for the n-th occurence.
Or is there another method that will help me do this more efficiently.

eally been struggling with this one, and i cant seem to find a simple method of doing it...surely there must be one? I have a list of values that i am loading into a variable. I am trying to split that variable by the whitespace that separates each value...the only thing is the whitespace varies in size. eg.

Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.

I have brought an array in from a range in excel. This works fine. Through debugging i can see the values are brought in correctly.
Issue is I want to see if a string exists within that array (or cells).
I have tried lots of things and pretty much mutilated my code but here it is:
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim folderinfo As String

I bought acheap USB barcode reader so i could play around with some hypothetical situations. I've managed to get a good chunk of stuff worked out, and had alot of fun along the way. But i thought to myself what if the same tag is passed back along the chain due to production defects and requires remaking.
When it returns to the station to be retagged complete, how do i set the condition for it to search to see if the bar code string already exists in the database prior to either adding a new row (if if returns negative) or to append a cell in the table if the search retuens a positive result.

I need to check if a webpage exists if it does whether a certain string exists anywhere on the page. Preferably I'd like to do this without a webbrowser control, so that images don't have to be downloaded and it doesn't have to be rendered.

I have two tables, dt & dtResults.dt contains 3 columns named: vchInstrumentAnalyteID, bintAnalyteCodeID, & vchAnalyteCode dtResults contains several columns including the columns in dt
I want to get vchInstrumentAnalyteID from the first row in dt and test if it exists in the vchInstrumentAnalyteID column in dtResults. If it exists, I want to use that value from dt to filter rows in dtResults and fill all the filtered rows with data from that row in dt. Then loop to the next row in dt.
I have this code, which is close to what I need, but I can't get it working.

I've been working on this program all week and I've been able to finally get it to work except for one problem. The program is suppose to parse strings from a text box to a list box and then from a list box to a text box using the users choice of delimiters. I can't seem to figure out how to get the last comma off the end of the list. ie cat,dog,elf,It seems it should be easy, but since I've worked on this program so long I believe I can't see the forest for the trees. I don't want for you to do my work for me.

I am developing an appilcation which requires a text box with auto-complete/suggestions (drop down) for multiple words (seperated by a delimiter like space) like the tags text box here in SOF. E.g. I start typing 'app' it should show all words in the suggestions list starting with app, and when I enter a word and press space and start typing a new word it should show all suggestions for that part-word.

I'm trying to use VB.NET to parse a very large plain text file (2 GB). It is a database and has a field delimiter of SOH and a record delimiter of STX. I want to separate the fields and records of the file.
I would normally read each line of a text file and then use the split function to separate out the fields. I can't use this approach as there isn't always a delimiter on every line.
Is there any way to read a file until STX is found (rather than one line at a time)?
