.net - Remove Single Quotes From All Cells In A DataTable?

Apr 2, 2009

I have a table with many values inside of it that might have single quotes around them. I need to create a duplicate table without those single quotes. I can't modify the original table as I need to use it, 'as-is' later.

I've done this with a table.Clone and using a foreach to loop through the rows and columns removing single quotes as I need and then putting that new row into the new table. It works and it's straight forward.....but

I'd like to do the same thing using LINQ. This was my attempt....

Dim myResults = From myRow In dtTable _
From myItem In myRow.ItemArray _
Where TypeOf myItem Is String AndAlso _
myItem.ToString.StartsWith("'"c) AndAlso _
myItem.ToString.EndsWith("'"c)

I had trouble finding examples that weren't looking at a specific column in the DataRow. It looks like my code does pull back all the matching results - but I'm at a lose for how I can create a duplicate table/modify the values?

The only requirement is to not using a For Each; as I already know how to do that. I've gotten closer - but I still can't seem to create a new row or a new table.

My new approach hits a dead-end when I try to do this:

Dim MyNewRow As New Data.DataRow With {.ItemArray = myRemovedQuotes.ToArray}

The Error message I get says, "Error 1'System.Data.DataRow.Protected Friend Sub New(builder As System.Data.DataRowBuilder)' is not accessible in this context because it is 'Protected Friend'."

C# - Using SelectNodes With Attribute Having Single Quotes And Double Quotes?

Nov 9, 2011

Is there any way to use selectnode with the attribute having both single and double quotes? If we are having single quote in the attribute we can use like below,

nodeList = root.SelectNodes("//book[contains(title,""'attribute'"")]")

If we are having double quotes we can use,

nodeList = root.SelectNodes("//book[contains(title,'"""attribute"""')]")

how can I use an attribute ['attribute"] having both single and quotes in SelectNodes.

SqlCommand Parameter / Replace A Single Quote With Two Single Quotes

HTML - Regex To Remove Quotes From Img Tag?

Mar 9, 2011

I need to remove all quotes from an image tag found within lots of other text. For example, I want to make

<img src="folder/image.gif" target="_blank" />

into

<img src=folder/image.gif target=_blank />

I'm using vb, and need to use a regEx specifically for the img tag and not use replace. The img tag can be in a block of other text, so I need to use regEx to search for the <img and then within that until I meet a /> I need to remove all quotes.

Adding Records To An Access Database Where The Data Contains Apostrophes (single Quotes)

Oct 5, 2011

The apostrophe is used to separate data when adding records to an Access Database data table using the "INSERT INTO" SQL statement. Having apostrophes in the data really screws things up with this new software. Is there a simple workaround? Is it possible to specify a different character? Is it possible to add data without using SQL Statements? I also noticed that the new OleDbDataAdapter Add Method generates the same SQL Error because it apparently creates an "INSERT INTO" SQL Statement.gh

Quotes In Quotes Creates Error That Stops The Making Of A Desktop Shortcut?

Dec 27, 2011

This should create a desktop shortcut but instead it spits out an error that is because of the quotes inside quotes. They need to be there, I know this is the problem as I have tried without them and it has worked. Another problem though is that it creates the shortcut (when Idon'thave quotes in quotes) but wraps the whole TargetPath in quotes making the shortcut unusable. Here is my code:

Hide DataGridView Buttons Only For Certain Cells And Show The DataTable Column Value Instead?

Oct 27, 2011

I searched for this topic and all the examples are in C# (and they have errors as they will not convert with a C# to VB converter). I am using VB.net 2005 and would like a sample that work for it. I have a loop that goes thru the DataGridView and changes the row color based on a column/cell value from the binded DataTable (shown below). I'd like to add to the loop (where the comment is) and also hide the button for this cell and let the "In Process" show in the cell instead.

Retrieving Single Element From Datatable

Sep 11, 2009

I have a string array (values) whose elements look like this
1xxx:val:timestamp
1xx1:val:timestamp
and so on....

and a datatable that contains all the valid ids (the 1xxx numbers) and their corresponding names. I need to check whether or not the table contains the id and if it does i need to get its name.

This is my current code

Dim tbl as DataTable = GetTable("Select ......")
tbl.PrimaryKey = New DataColumn() {tbl.Columns("sensor_id")
For each value as string in values

[Code]....

but it seems like it is a round about way since I already know the element exists in the table and the select statement returns an array which i dont need because I know there will only be one datarow associated with this id. I feel like there should be an easier or actually more efficient way of doing this. If not oh well but I had to check anyway.

but this returns an array of datarows when i know I am only going to get one datarow from this query

C# - Regex To Remove Single-line SQL Comments?

Mar 23, 2012

give me a working regex expression (C#/VB.NET) that can remove single line comments from a SQL statement ?I mean these comments:

-- This is a comment

not those

/* this is a comment */

because I already can handle the star comments.I have a made a little parser that removes those comments when they are at the start of the line, but they can also be somewhere after code or worse, in a SQL-string 'hello --Test -- World' Those comments should also be removed (except those in a SQL string of course - if possible).Surprisingly I didn't got the regex working. I would have assumed the star comments to be more difficult, but actually, they aren't.

As per request, here my code to remove /**/-style comments (In order to have it ignore SQL-Style strings, you have to subsitute strings with a uniqueidentifier (i used 4 concated), then apply the comment-removal, then apply string-backsubstitution.

static string RemoveCstyleComments(string strInput)
{
string strPattern = @"/[*][wds]+[*]/";
//strPattern = @"/*.*?*/"; // Doesn't work

VS 2010 Switching DataViews For A Single DataTable?

Jan 13, 2011

I have a data table a simplified version of which is represented below:

Number | Group | Date | Client | Amount
--------+-------+-------+--------------+--------
1 | 220 | 28/12 | Company A | 0.345
--------+-------+-------+--------------+--------
2 | 220 | 29/12 | Company B | 0.451
--------+-------+-------+--------------+--------
3 | 240 | 26/12 | Company A | 0.510
--------+-------+-------+--------------+--------
4 | 240 | 27/12 | Company A | 0.510
--------+-------+-------+--------------+--------
5 | 220 | 30/12 | Company C | 0.151
etc.

I have a default view which represents the whole table.

But I need also a different view which represents the summary of the same data.

Code | Amount
------+--------
220 | 0.947
------+--------
240 | 1.02

In other words, I need grouped totals.

The question is - is it possible to accomplish by preparing a dataview for the datatable and assign it to the .DefaultView property (I need a user to be able to switch between detailed and summary views). Normally I always prepare views in a database but now I need to do it with DataTable and I simply have no experience of working with DataView class.
