Asp.net - Replace(Environment.NewLine, "<br/>") Is Not Working As Expected When Displaying Text On A Web Page
Nov 24, 2011
I'm not sure why the following code is not working as intended:
CODE:
Where litMessage is the name of the literal control and messageBody is the name of the string variable.
My intention is to output a string onto a web page and to replace the line breaks with a br tag so that it can be displayed on the page correctly. However, nothing is replaced. When viewing the page source, it looks like the line breaks still exist in the string. Similarly, when displaying the string via MsgBox, it displays normally as well. I have also tried wrapping the output with the pre tag and it displays the line breaks properly as well.
The string was originally entered by a user through the use of an asp:Textbox and saved into a MSSQL database. It's retrieved and displayed on another webpage using an asp:Literal control. The only thing that happens to the string before it is submitted is that it is trimmed (i.e. textbox.Text.Trim()).
Perhaps there is something I did not consider?
Edit #1: Due to time constraints, I've decided to just wrap the text with the pre tag. It's an acceptable work around as it preserves the line breaks. Unfortunately, it doesn't explain why the code didn't work in the first place. In the meantime, I'll just leave the question unanswered until I find a proper answer.
Edit #2: Solution found and answered below. UpdatePanel tag added to the question for future reference.
To set the text of the excel cell to an multiline text i have used "sometext" & Environment.NewLine & "sometext".but it adds an space at the end of the first line
I use Environment.NewLine, my colleagues use vbCrLf.When I'm doing a code review for them I want something that I can point to to say "use Environment.NewLine instead of vbCrLf"
Or, am I just peeing in the wind, and it doesn't really matter ?
Environnent.NewLine seems to be resolving to two spaces " " (as are vbCrLf and ControlChars.CrLF). Using StringBuilder, AppendLine is doing the same.I've been racking my brain and searching the Internet trying to figure out why this the way it is, but am coming up empty.
I am trying to generate .bat file based on user interface decisions. I need to have separation between lines. I'm trying:
Well I have been able to figure this out but what I want to do is make my string have a new line after 20 chars. I know how to find how many chars the string has but not how to insert environment.newline at 20 chars.I am using this to find the string length
If string.Length > 20 then 'Need to be able to insert environment.newline at 20 chars Else 'Normal string End If
In Visual Studio 2010 Ultimate, a VB.NET WinForms project, I am getting incorrect values for Environment.NewLine and StringBuilder.AppendLine; look at the result in a hex editor, they are resolving to two spaces.
I am trying to create radiobuttons, and then create code for them after they are created. I have the code to create the radiobuttons. What I want to do is create a sub for the event of changing the check value for the radiobutton. Or to have the check value recognized by a button click. For example, you click the button and if the first radiobutton has the circle filled then a msgbox comes up and says hurray. My code so far is this:
I have an Excel worksheet with a Source Cell and a Target Cell.Via GDI API functions, I draw a temporary gradient fill over the source cell which happens to be cell "D6"then, I make a transparent copy of the temp gradient fill drawn over the source cell and place the copy (ie the transparent gradient fill) over the target cell which happens to be cell "D9".
I want to fetch data from a database table modify it and update it without being dependent on the database provider and the database structure, because it will be part of a library.My first attempt was as follows:
'factory defined somewhere else as DbProviderFactory 'connection is a working DbConnection Dim selectcmd As DbCommand = connection.CreateCommand()[code]....
it did not work. After further investigation I figured out that the Commands the CommandBuilder generated were useless, because it inserted ? instead of @param1 for all Parameters. It generated something like INSERT INTO tbl1 (field1, field2, field3) VALUES (?, ?, ?) for the InsertCommand.I would really like to use the CommandBuilder, because it is simple and I don't have something complicated like JOINS.
Dim clcexists = (From p In dbContext.Signatures _ Where p.StudentID = people_id _ And p.ContractType = "clc" _ Order By p.ID Descending _ Select p)
Later I check whether any rows exist in clcexists using IsNothing like so:
If IsNothing(clcexists) Then ' If no CLC is on file. clcfirst = Date.Now.Subtract(year) clcdate = clcfirst
[Code]....
But IsNothing() is not functioning like I expect. There is no row in the results table, but it is still acting as if there is and going to the Else clause.
I am running Windows 7 pro and using Visual Basic 2010 express.I have written a small program to switch on a USB relay which is controled by a serial port.I have debuged the program and it appears to work correctly. I have published the program and if I start it from thr run menu / desktop shortcut / or through explorer it works as expected.
However I have tried to run it by the Task Scheduler and then it fails to run as expected. I have a small section of code that checks to see if the serial port is present if not I have used messagebox.show to ask for the relay to be pluged in. In every case other than when running through the Task Scheduler the messagebox works with the Task schedulerit doesn't show the messagebox and the program hangs I have included the code I have used.

[URL]. I have a Multi-Line textbox with several accounts in it. They are in email@email.comassword format on separate lines. All the code is right, but it goes really weird and loops like 3 times before logging in. Eventually logging into the last account on the Textbox instead of the first. It should just login to the first account...Logout....Login to the second account...Logout and continue the process.
If you want to test it, just put a web browser and a textbox1 multiline box, a button and enter a few working hotmail accounts and you'll see. Check line 17 Looks like a lot of code, but line 17 is the only bit that needs to be looked at. The rest is just junk/non-relevant to this problem. It separates the accounts perfectly and stuff, but just wont login in the right order.
I have declared a String variable(PC) for use within another String variable(currentQuery) to form a SQL statement to pass to my SQLDataAdapter variable.
I'm performing this action to change the string variable(PC) for the different onClick events I have.
It seems i can change this variable (PC) within my onClick event handlers and the 'PC' variable will change when I apply it to a testing Text Box 'testTextBox' but not for the currentQuery variable.
Do i need to perform this action as a function or am i missing something obvious - code below - I don't want to spend time writing a function to return a string value for my SQL statement if i can just tweek something in my code (below).

I have more than 30,000 rows in a table. It takes a lot of time to load all the data in the gridview. So I want to display 100 rows at a time. When I click next page button, another 100 rows should be displayed. When I click previous page button, previous 100 rows should be displayed. If I type page 5 in a text box, then I want to jump over to the 5th lot of rows.
I also want to display how many pages there will be. Can we implement this concept in vb.net [winform] gridview. I am using database PostgreSQL.
I have a form with a split panel. In the one split are a group of buttons which I want to programmatically change the color of the last pressed button.The following loop seems to run correctly and set the colors correctly but the form doesn't represent that. Once the loop is completed and I recheck the button colors, they revert to previous state.[code]I can get the desired effect by doing the below code but seems less elegant and would obviously require updates as buttons would be added or removed.[code]
I am working on a GUI for a simulation program. The simulation program is a single .exe which is driven by an input file (File.inp placed in the same directory). The Original.inp file functions as a template from which the form reads all the values into an array. Then it changes these values reflecting the changes done by the user in the form. After that it writes all the new values to File.inp. By pushing the "Run" button the Simulation.exe file is executed. The folder structure looks like this:
[Code]..
Ideally I would supply only the GUI, the user would select the working directory and then the GUI.exe would create an input folder and extract the Original.inp and Simulation.exe in the appropriate locations. So far I have only managed to include Original.inp and Simulation.exe as "EmbeddedResources" in my VB project and I have let my code create an input folder in the working directory chosen by the user.
how I can extract the .inp and .exe file into the correct directories? I've searched on google, tried File.WriteAllBytes and Filestream.WriteByte but did not get the desired results. The problem with File.WriteAllBytes was that I could not point to the embedded resource ("Simulation.exe is not a member of Resources" and with Filestream.WriteByte I got a 0 kb file.
I was toying around with some of the linq samples that come with LINQPad. In the "C# 3.0 in a Nutshell" folder, under Chater 9 - Grouping, there is a sample query called "Grouping by Multiple Keys". It contains the following query:
from n in new[] { "Tom", "Dick", "Harry", "Mary", "Jay" }.AsQueryable() group n by new {
However it always returns 0. I've checked and the GetPartCost function executes and returns a non-zero number but the list item cost properties are never updated.The property is just a simple property,
Public Property Cost() As Double Get Return _Cost[code]....
If I set a breakpoint in the Set of the property, it never gets hit.
I got a textbox and a richtextbox... When i click the Send button.. the text from theTextbox go to the richtextbox and a new line (Enter)....So i got thatRichTextBox1.Text += TextBox1.Text & ("{Enter}")It work... but it say your text and ("{Enter}") .... it doesn't do a new line...

After I ran it, I had a file a.txt in my debug folder but the size is 0 bytes (and when i open it is empty of course) Shouldn't the output had "asd" in it ?
I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString") Private _myObjectLongName As New ThisObjectLongName("SomeString")
I am trying to implement a webservice but I am receiving this error :Client found response content type of 'text/html', but expected 'text/xml'.The request failed with the error message:Quote:

I am reading a text file and I need to replace a few areas with new text that I marked with {0}, {1}, {2}, {3}, {4}, {5}, {6}. So I load in the text, save it to a string variable, and then use String.Replace but it's not working.

I put all the data items into an array, then did this after loading the text file:
I am trying to replace text in my xsl file. I have to replace all the http and https. But I can leave any links that start with <a href>
Ie; http://www.google.com has to replaced. But < a href="google.com">google.com</a> has to remain as it is.
I am using regex to find all the http(s) and a hrefs in the text. I am struck here.
My code is,
Dim href As New Regex("(<a.*?>.*?</a>)", RegexOptions.IgnoreCase) Dim hrefs As New Regex("http(s)?://([w+?.w+])+([a-zA-Z0-9~!@#$\%^&*()_-=+\/?.:;',]*)?", RegexOptions.IgnoreCase)
[Code].....
I am trying to use Regex.Replace to replace my https. But I am unable to write the evaluate function.
My regex.replace replaces all the values with a single value.
