I am using a path comparison to find any children tags which works well when there is only 1 tag selected. This is my code for when multiples tags are selected but it is not working. Can you point me in the right direction?
Single Tag Selection (working)
Dim tagpath = uxTags.SelectedItem.Text
lnqCases = From i In lnqCases Where i.HelpDeskTagItems.Any(Function(x)

I'm just trying to implement a 'no duplicates' catch on my insert customer form, but it just slips through my if statement to the else everytime. This is the source. Also I tried a .Equals with the same results :(

So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
String myTestValue = "NotModified";
TestMethod(myTestValue);
System.Diagnostics.Debug.Write(myTestValue); /* myTestValue = "NotModified" WTF? *[code].....
And what is going on under the hood? I would have bet my life that the value would have changed....

I am running the following query against a database of research reference works (books, articles, etc.):
SELECT [Names].[Last] AS Authors, [References].PubYear AS [Year], [References].ShortTitle AS Title, [References].SourceWork,
RefTypes.Description
FROM ((([References] INNER JOIN
Contributors ON [References].ID = Contributors.RefID) INNER JOIN
[code]....
This query returns one row for each Author (contributor type=1), of the specified reference. The rows will all be exactly the same except for the Author last names taken from the NAMES table. For example:
Author Year Title SourceWork Type
--------------- ------- --------------------------------- ----------- ----------
Rahner 1966 Revelation and Tradition Null Book
Ratzinger 1966 Revelation and Tradition Null Book
I'm looking for a way to consolidate the string data from the Author column into one string, so that this can return a single row with the Author field looking something like "Rahner, Ratzinger" -- like one could do if it were numeric data by using the GROUP BY clause with an aggregate function such as SUM or AVG.

I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

I'm sure there are better ways to do this and i am open to suggestions. I'm not worried about speed i figured get it to work then i could improve it but my problem is mynewstr2 is not being set to the last value of mynewstr for some reason.(probably something silly im overlooking right now). at this point just converting the image to a string i can work with for my very basic ocr.

If I send a String set to Nothing as an input parameter to a SQL stored procedure, and in the sproc it's like this @MyString Char(9) = NULL, what does it turn NULL into? Because I'm firing the sproc and it's not firing the statement that says IF @MyString = NULL... So I don't know what it is... Or how can I pass the string as a NULL if nothing is passed as a parameter to my calling function?

i have 2 queries in vb.net with an if clause -
if x=0 then
insert into table1
else
update table1
both queries have 5 fields. now what i want to do is after this insert or update takes place, i need to look at this inserted/updated record and compare it with another table (table2). Especially for update, i have 5 fields in both tables. if any of the 5 fields dont match with table2, then i insert a new record in table 2 which is the updated record in table 1.

My approach is to setup three different queries and save to three different variables and then save the data in the three variables into the new table. I have the new table setup in ms access.As you can see from my code, I had tried many different ways to generate my sql statement but none of them works. Now I am trying to figure out which part of the sql statement goes wrong by testing one by one. The two that is uncomment:
1)Dim SDFH As String = "SELECT SegmentCode FROM SegmentPlantTable WHERE DatePlanted < cdate('" & Date.Today & "')"
2)Dim SDFP As String = "SELECT SegmentCode FROM HarvestTable WHERE DateOfHarvest <

VS 2008 VB/I've implemented an interface to a .com program written in c++. I'm trying to access a data structure array(uNewValues) of type PLCCOMMLib.ANALOG_CONTIN. uNewValues should be a datastructure array of several elements (iSigIDCount). My problem is I only get the first array element of the datastructure.I've tried several methods and looked into marshalling but don't understand how to implement marshalling if that is the correct option.
Code below:
Public Sub AnalogContinUpdate(ByVal iSigIDCount

I have this string that shall come in from another file. The string has maximum length of 102 digits. I need to compare the string with numbers in a pair and delete those from that string.
e.g - 6125223659587412563265... till 102
numbers that compare with this string-
first set - 61
new string = 25223659587412563265
second set - 36
new string = 252259587412563265
and so on. the set of numbers shall go to maximum of 51 pairs = 102, which shall give an end result of string = "" How can i achieve this in a loop?
this is not answer, this is editing the question. i dont know why but the edit button just vaniashed so i have to edit question here. No duplicates will ever be in this string. and in the end when compares are done, i want to see what numbers are left in pairs.

I am making a question and answer game, and I would like to be able to give the user some slack in the answers if they were to misspell a word by a letter or two, like if the answers was Jumps and they type Jump if you did a comparison of them like If string1 = sring2 then do whatever, but obliviously those to string dont match, so it would return false, even though it is the right answer, I came up with this routine to compare two words and if the percentage of the letters are higher then 82 % right it will give you credit for your answer.

I have a tblVersion that contains the versions of my application:
VersionID Version
VersionID is a bigint primary key, version is a ntext column that holds the current version... I want to be able to pick the row that has the highest version number, but version could be in this format:
MyApplication 1.0.1
If I try to convert that to a int32 it will throw an exception obviously. I would like to know if some of you have a idea how to solve this issue. I could of course make sure the column will only contain numeric values but this gives a little more flexibility.
