RegEx To Get Only Names From Sting?
Nov 26, 2011This problem I guess is easy to solve for an "RegEx" master :P
My string look like this:
"name":"stefanACM".id...
"name":"test1".id...
"name":"test2".id...
So I need RegEx to get only names from sting (stefanACM,test1,test2). That means I need RegEx to find string between "name":" and ".id
VS 2008 Sting To Int From Array?
Oct 5, 2008i'm stuck on something so easy, i've googled, tired various methods but cant get it to work. Imagine if you can, i have an array (set as a string type) but the second slot holds a numebr that i want, e.g. 2333.
So to grab it i use the following code, however as my sport array is set to a string it wont allow it. Like i said i have tried a few ways but nothing works. Such a stupid and simple situation. I'm much much better with actionscript surely its just a string to int conversion?

Replace The "1" Sting Text With A Reference To A Temporary 1-row Table?
Jul 27, 2009This is my first time working with VB, though I've been working with VBA for a couple years now to automate office routines at my work. At my last job, I saved about 3 hours a day with my automations, and at my current job, I'm shooting for about the same. The problem is, though I have a high affinity for computers and technology, I never studied to be a programmer, and so I really can only tweak code I find online, and then eventually build up enough of my own subroutines to accomplish the tasks at hand. This is why I'm posting here on this forum, I've reached my wits end for what I imagine is a relatively simple problem. This was initially written in VB 6, but I imported and converted it with Visual Studio 2008, and it runs fine. This demo code is set to populate a PDFwith some sample string text. What I want to do is to replace the string text with a reference to data in either an Access or SQL database - I prefer Access, but either will work. Here is a sample of the demo code I'm working with:
[code]...
On this last line, I want to replace the "1" sting text with a reference to a temporary 1-row table I'll be generating from an Access Query, with Field Names to match the Form Field names of the PDF, So I've setup an Access DB with the following configuration (in reference to the path, I'm using Vista x64):
[code]...
I have also imported this table as a dataset (my understanding is that the import into Visual Studio 2008 makes it a typed dataset?) so either referencing the access DB directly or the imported Dataset should work. I can also setup the Access DB as a SQL DB instead if it would make it easier. Now, if I was programming in VBA, I might do something like this:

Test Certain Cell Values To See If They Contain Subtrings Of A Certain Format At The END Of The Cell Sting Value?
Feb 9, 2009I am trying to test certain cell values to see if they contain subtrings of a certain format at the END of the cell sting value.E.G.I have cells with the values...
324f5
346-ssth
4565-Q1-09
dsfsd46
[code].....
I want to run a macro that searches through the cells and tests to see if they have a substring sitting at the end of the value that is in the format "-Q[number]-[number][number]" OR "-[3 LETTER MONTH ABBREVIATION][number]-[number][number]" OR "-[3 LETTER MONTH ABBREVIATION][number][number]-[number][number]"and then if the test is true, the cell color is changed to RED.So if I ran the macro on the example I gave above, it would turn the cells with the following values red:
4565-Q1-09
454354-FEB2-09
546-5-MAR03-09
I can do all the VB side of things but I don't know Regex but know it would help. I'm in a bit of a rush to finish this job for work because I finish working here in 2 days and need to get it done before I leave!

May 29, 2012I'm trying to put sub-child values from XML into a dictionary collection using LINQ. I've done this with lists and custom collections which follow the same structure as the XML but am unable to search for specific values.

View 6 RepliesCan't Get A List(Of <my Class>) From A Dictionary In .NET
Jun 11, 2010I have a Dictionary with key of type UInteger and the value is List(Of Session) where the (Public) class Session contains a couple of variables and a constructor (Public Sub New(...)). Some of the variables in my Session class is:
Private count As Integer
Private StartDate As Date
Private Values As List(Of Integer)
and a couple of methods like:
Friend Sub Counter(ByVal c as Integer)
count += c
End Sub
There is no problem to add values to the Dictionary:
Dim Sessions As New List(Of Session)
Dim dict As New Dictionary(Of Integer, List(Of Sessions))
then some code to fill up a couple of Session objects in Sessions (not shown here) and then:
dict.Add(17, Sessions) ''#No problem
Sessions.Clear()
Sessions = dict(17) ''#This doesn't return anything!
The Sessions object is empty even if the code doesn't returned any error.Is my class Session to compex to be stored in a Dictionary?
Filter A Dictionary To Return A List?
Apr 23, 2012I know I can do this with a for loop cause that's how i'm doing it now. I was hoping for a more efficient way to accomplish the task.
I have a dictionary(Of Integer, Boolean) or Of String, Boolean. i want to get a list(of integer) or Of String from the dictionary where all the values are true(or false depending on what i need at the time)
and to generalize it or "black box" it, it could be any dictionary(of whatever, whatever) and return a list(of whatever) where the value = whatever i'm looking for at the time.
string, string where value = "Closed"
in short: i want all list of all the keys who's value = some criteria
my current code:
Public Function FindInDict(Of tx, ty)(thedict As Dictionary(Of tx, ty), criteria As ty) As List(Of tx)
Dim tmpList As New List(Of tx)

Use Linq ToDictionary To Return A Dictionary With Multiple Values In The Dictionary Items?
Jan 25, 2010I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

Cast/convert From List(Of DataRow) To List(Of String)?
May 22, 2012I'm trying to solve a problem regarding types of list. First of all I have a stored procedure in my DB which does a select of a single column and I try to proceed it in my app in VB. By making a method function I declared a DataTable that loads through the SqlCommand(with the CloseConnection behavior). After that I publicly declared a List(Of String) which needs to be populated with the rows/items from the stored procedure that is on the way. Below is my snippet of the code:
Dim dt As New DataTable()
Try
If conn.State = ConnectionState.Open Then
[Code]....
It's LPrefix = collection.Cast(Of String)() where I get an exception error telling me that I can't really convert it. The old fashion way is to iterate with for/for each loop but that's not what I want for best use of performance especially if the list will have thousands of rows from a single column. So basically, I want to insert those items from that DataTable to the List(Of String) without For/For Each loop.
