I am developing a asp.net web application, i have a string (with a value in it from a database), with multiple lines that i put in a TextBox with mulitline type. (textarea)
Now the problem is, that in the string are multiple lines, with much empty space. so i want the remove only the double linebreaks.
example of my textbox:
{empty}
{empty}
'This is some text in the textbox on line 3
'some text on line 4
{empty}
'some text on line 6
{empty}
{empty}
'some text on line 9
{empty}
now somehow i want to remove line 1 and 2, and line 7 and 8

View 5 RepliesWhy does this
string test = "Text1, Text2";
string [] tests = test.Split(", ".ToArray());
returns this
[0] = "Text1"
[1] = ""
[2] = "Text2"
what's with the quotes in tests[1] ? I thought the output would be like this
[0] = "Text1"
[1] = "Text2"
I have string. There are no items to show in this view of the "Personal Documents" then assign to string str variable string str ="There are no items to show in this view of the "Personal Documents" library" Now planning to replace "" and make it to actual string to str object.

str = str.Replace(@"",string.Empty);
I want str value should be string str ="There are no items to show in this view of the "Personal Documents" library" I need to find this string in another string. While searching into that string. I couldn't found because str contains "".
i have a strange error creaping into my web app but am unsure as to how to fix it. When i run this code on my debug workstation it works fine but when i transfer it to my server things seam to go wrong.
dev station (windows 7) + VS2010
regional and language settings all set to uk
server (windows 2008r2)
regional and language settings all set to uk
What seams to be happening is that when converting a string to a double it works correctly on the dev environment but moves the decimal place to the end on the server.
example code(vb)
dim lat as string = "52.983829"
dim long as string = "-0.036500"
dim latint as double = lat
dim longint as double = long
now on the dev server the value of latint is 52.983829 as you might expect but on when published to the server it becomes 52983829.0 the same with longint on the dev staion it is -0.036500 but on the server it becomes -36500.0 i get equally confusing problems if i try to change it to an integer instead.
I am trying to insert dynamic data into a onclick property for a control the code looks like this
onclick="openRadWindow('<%#Eval("ID";) %>','<%#Eval("ParentObjectID") %>');"
I cant get it to fire and the trouble seems to be the double quotes, what is the correct method on escaping the quotes so that this fires.
I am using .Net Framework 3.5 on an ASP.net web project using jquery.ajax to make web service calls. My web service returns objects serialized as JSON by specifying the content type of my POST as "application/json". I would like just one of my many properties to return a non quoted javascript function name instead of a quoted string. Serialized as such:
{"dataInit": functionName, "id": "myID"}
instead of
{"dataInit": "functionName", "id":"myID"}
I am writing value to a textbox from handler(ashx) file. But the problem is that when the value contains double quote or single quote the textbox only shows the value before that quote and omits the the string after that quote.
For eg Value is: Hi "there
The textbox shows: Hi
This code works somewhat, but it won't place all of the text into the textbox.. If I change a few things I get an error where I highlighted the code in red. Conversion from string "" to type 'Double' is not valid. But the code works, like I said somewhat, as you see it, it just doesn't load all of the text to the text box.555632.txt

But it is still giving a "String was not a recognized as a valid DateTime." In the full context, I have a webpage with a formview on it and within the formview is a TextBox control that is taking a user input such as "1999" then an ObjectDataSource picks it up and runs it through a BLL. And within the BLL is where I am trying to convert it before it gets inserted into the database.
