i'm working on a project after returning to coding after four years off and i'm a bit rusty. My problem is that i'm creating a login page and i've got a few people with two last names. in the login box they would put their full name but in the database they have spaces between them. An example would be the name mighel santa anna.

I would like to pass a whitespace character by using the System.Text.Encoding.ASCII.GetBytes(" "), and System.Text.Encoding.Unicode.GetBytes(" ") , where " " is the whitespace Character required. What do I need to type (" ") to get a whitespace character passed.?
View 6 RepliesI need to split a string at all whitespace, it should ONLY contain the words themselves. How can I do this in vb.net? Tabs, Newlines, etc. must all be split! This has been bugging me for quite a while now, as my syntax highlighter I made completely ignores the first word in each line except for the very first line.
View 4 RepliesI'm having difficulty with some strings of varying 'meaningful' length from a different database (not under my control) that I am trying to trim in my vb.net code.
I only want to remove TRAILING whitespace... therefore, I can't really use .trim method.
The reasoning behind this being that the field sent from the french database usefully uses a <space> to represent a 0 (as you do).
The string is always the same length but the meaningful length can vary, an example being 95WO<space>5CA<space><space><space>...etc
Or it could be this...
<space><space>WO<space><space><space>... etc
Or this...
<space>5WO95CA<space><space><space>...etc
I've got my methods in place to split the string into pairs and perform various lookups but until I can remove the trailing whitespace I'm a bit stuck
How do I trim all whitespace in an array?[code]
View 2 RepliesI have text like this format "term: 156^^^:^^59 datainput" Or "term: 156^^^:59 datainput" or "term: 156:^^^59" The "^" represented white space. Notice the white space between the the two numbers and the colon. There 2, 3, 4 or even 7 white space between the two number. I want to remove these white space so that the text can be in this format:

Is there any way in VB.NET to remove all of the whitespaces between tags in HTML? Say, I've got this:
<tr>
<td>
The string I've built is an entire HTML document, and it counts everything before those tags as legitimate space, so I need to trim it out. Is there a reg ex or function out there I could use to do this?
There is an option in Visual Studio (since as far back as I can remember) that allows you to see "Whitespace" in your code. This is often seen in file differential viewers as well.
I'm wondering if anyone knows how this can be accomplished in VB.net (or any other way) so that i could use a similar type of display option in my software.
I have not yet tried to do this but my only first thoughts would be to override the "paint" of the textbox to actually add the little tab "arrows" and space "dots" manually via GDI, or create a texbox control from scratch. Seems to me there could be an easier way to do this.
I am developping an app which talks across a network and will eventually be used to read in a text file (on the client) and transfer it to the server. Currently, the server and client succesfully connect to each other using the Tcplistener/Tcpclient classes. I am now trying to send some data across the network using the networkstream class, which I have implemented.Currently for testing purposes i am sending a char array which contains the characters "hello" which succesfully sends and outputs to console on the server. Although, "hello" is followed by a long list of whitespaces. I have tried converting this to a string array on the server and/or client and using the string.Trim() function (amongst trying many other things over the past couple of hours) although the output remains the same.
View 19 RepliesI am getting extra whitespace characters rendered in my horizontal list of anchor tags below. This is causing a major CSS styling issue for me. I know this question has been addressed as far as a C# workaround is concerned (asp.net mvc razor extra space), but can anyone help me with a VB workaround? I don't have the advantage of curly braces to eliminate all whitespace in a single-line If condition.
I have managed to work around it for now by writing an HtmlHelper extension method, but this dynamic code is only used in one place (the master layout page). It seems to me that this should really be done in the .vbhtml page. Here is the erroneous code, along with commented-out attempts at workarounds. The goal is to create a horizontal list of "sibling" pages based on a site map, with slightly different styles for the current page's link and the link just before it. [Code]
I have an ASP.Net 2.0 textbox which I need to be validated as having some content, but where whitespace alone is valid input. A required field validator seems to reject a pure whitespace input as invalid. A regular expression validator won't fire at all on empty content. Is there a simpler way round this than using a custom validator control?
View 1 RepliesI have a BindingSource that is my DataGridViews data source. I want to filter for all rows where column1 is blank. For example, one row may contain a null value, some rows may contain just white space, and other rows may contain text. How do I show just the rows with text (or numeric, or date) values?
Also, how do I filter for non-blank rows? This would show me all rows that contain a blank cell.
Me.BindingSource.Filter = ?
Does anyone know if there is a command to remove extra whitespace (blank lines) when coding?
View 8 RepliesI have a web application where the user uses an HTML editor to input some formatted text to show on the website. This text is stored, as HTML, in a database. It turns out now, after some time, that users are sometimes entering whitespace (newlines, spaces, etc) before and/or after the text they are entering, and this whitespace shows up in the rendered text on the page. Multiple sets of this text are displayed top to bottom, and due to this whitespace the separation between bits of text varies, which doesn't look very pretty. So, I've been asked to get rid of the whitespace automatically.
Seemed like an easy task at first, I'd just call Trim on the string. But that won't work, the 'whitespace' when rendered isn't actually whitespace at all, it's a bunch of <br /> or <br> or <br></br> tags, or spaces such as, even empty paragraphs <p></p> sometimes. So calling Trim won't help, I need to get rid of all the tags that would render as whitespace.
The HTML editor control I'm using may or may not have built in support for this, but it doesn't matter, the database is already full with texts that contain these newline tags, so the best option I can see is to simply trim this whitespace before displaying it on the page. [Code]
I am trying to learn how to use the tcplistener and tcpclient classes. While I am attempting to compare something that is sent from the client to the server it seems that it adds a bunch of spaces, the reason I know that is if I write to the console what was sent it adds a bunch of spaces at the end. Is there anyway to get rid of it and just get the original text. I tried trim() but that didn't seem to work but I could have been using it improperly.

I'll have a go at describing the algorithm which I think is intuitively obvious - (for a particular selection) make each token on a line as left as possible, but not more left than any token of the same index on any of the other lines.
Imagine there is a line, in a text file, with three values separated with commas.

I have 2 tables in my database (SITES and RECORDERS) SITES has only 2 fields (SiteID and SiteName)
RECORDERS has SiteID as a foreign key.
The primary key of RECORDERS is two fields, SiteID and RecorderID .I don't want to use a DataGridView for editing. I like the Details view and have dragged the fields to my form (using the Data Wizard). It adds the BindingNavigator to the top of the form and I'm able to go through each record of the RECORDERS table successfully.
What I am wanting to do is somehow select (through a ComboBox or ListBox)a SiteID and RecorderID (which will return one row) and have it load those fields in the controls just like it does with the BindingNavigator.I want to maintain bound controls to make the Addition and Deletion of records easier.
The reason for this is navigating with the BindingNavigator one at a time is quite cumbersome if I need to access a record near the end or middle.
My problem is to open a file, search for a particular word in that file, After finding that in line, add some text in the following line.Like for example I am searching for "Serach" in a file , and I found it in line 16.
