Javascript - Encoding String For Apostrophe In Asp.net?
Sep 20, 2011
I am having a problem trying to resolve an apostrophe related issue. I have searched SO,
My clientside javascript code is: var strUserText = uSettings.replace(/'/g, "'")
after the above line is executed, the form does a submit
document.form1.submit(); in code behind, a class retreives those values:
sUserSettings = request.form("strUserSettings ") the result is a semi-truncated string.Given the above code process flow, how can I save "John O'Brady's ASP Blog" in to a database?
I thought I was saving "John O'Brady's ASP Blog" but that isn't working.
Am just wondering if I'm doing something the long way round, so I thought I'd bounce it off the forum for opinion. I'm using the following code to write the contents of three text boxes into a table in an access database. [Code]
During testing I noticed that when an ' (apostrophe in words like can't) was used in the text boxes it would cause the app to halt. Figured that it was due to the ' being interpreted as a command so I could replace all of the ' in the text with a "unique" character before writing it to the database, so then when it is read back I could re-replace the "unique" character with the ' so the user sees what they have entered.
My question: is there a more efficient way of handling this ?
I just ran into what I consider a very strange issue in the execution of some code that I thought I had completely well-understood.
Basically, I was using this kind of notation:
If strOne.equals(strTwo) Then
rather than
If strOne = strTwo Then
I came from a c and java background, and using the '=' operator for comparison has always made me cringe, so I've used the .equals() comparison function thinking that it was equivalent. But just now some of my code broke. It encountered a string containing "Eagle's Nest: Dawn Patrol", used the .equals() to compare it to "Eagle's Nest: Dawn Patrol" and declared them not equal. I changed the code to use '=' rather than '.equals()' and it declared them equal. I also did this:
If strOne.Replace("'", "").Equals(strTwo.Replace("'", "")) Then
And again, it declared them equal.
This has me a little rattled because my code is filled with the use of .equals(), and I've used it assuming that it was no different than writing strOne = strTwo. I've scanned the interweb looking for information about this. I have not found any information about odd interactions between the apostrophe (or other) character(s) and .equals(). Microsoft's documentation does not hint at any subtle differences. how .equals() differs from '='
why the rowfilter property does not work if there is an apostrophe in present in the string. For e.g. , tempdat.DefaultView.RowFilter = "Mystring = '" & st & "'" the above does not work if st="mystrings's" under the column header Mystring.
I have the following update code which works fine. However, it prompts an error when apostrophe (') is used in txtdesc.text. For example if you type name's , the error message will be.. Incorrect syntax near 's' Unclosed quotation mark after the character string ".
query = "UPDATE dbo.TblProjects SET ProjectDesc ='" & _ txtProdesc.Text & "' where ProjectID='" & _ txtProjectID.Text & "'" cmd = New SqlCommand(query, conn) cmd.ExecuteNonQuery()
I'm using this code to convert string to ISO8859-1
[code..]
But the problem is when an user writes this caracter:

I think that my code is wrong. Because if I send the same string encoded "price+80%2BVAT", Why in VB.NET code not runs and in PHP runs fine? Is the same encoded string.
I have a long UTF8 encoded text string. The actual values stored in the string are hexadecimal. I want to convert the encoding and save to a binary file.
Is there a simple encoding.convert or other method to do this with?
Basically the output is twice as large as it needs to be right now. The long way of doing it would be a routine to go through the string two characters at a time and convert to byte array and then .writeallbytes I guess. It seems there must be a simpler way of converting this?
I am sending a DDE message to a client using System.Text.Encoding.ASCII.GetBytes(item) . However, before the message is actually sent, I would like to get the message coded where if the item="Ask" then item=Ask (string variable) and so on. The code is:
Protected Overrides Function OnRequest(ByVal conversation As DdeConversation, ByVal item As String, ByVal format As Integer) As RequestResult ' Return data to the client only if the format is CF_TEXT
I am not sending any sensitive or security information in the query string. I am currently using Base64Encoding along with MD5 Hash. I want to shorten my url as far as possible.
I need a way to compare multiple strings to a test string and return the string that closely resembles it:
TEST STRING: THE BROWN FOX JUMPED OVER THE RED COW CHOICE A : THE RED COW JUMPED OVER THE GREEN CHICKEN CHOICE B : THE RED COW JUMPED OVER THE RED COW CHOICE C : THE RED FOX JUMPED OVER THE BROWN COW
(If I did this correctly) The closest string to the "TEST STRING" should be "CHOICE C". What is the easiest way to do this?
I plan on implementing this into multiple languages including VB.net, Lua, and JavaScript. At this point, pseudo code is acceptable.
I've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.
The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.
I am using VB 2005 and MS Access 2007.Some of business name has apostrophe(') and I need to know how SQL deal with this name.For example
sqlStr = "SELECT * FROM AddressTable WHERE BusinessName=" & "'" & updateBName & "'" in this case, if updateBName is "Den's Nail", the real SQL is "SELECT * FROM AddressChangeTable WHERE BusinessName='Den's Nail'"
and this code generates Error Message.Is there any way to prevent error ?Or do I have to remove all apostrophe(') in Business Name?
I am using Virtual Basic with ASP.NET in Visual Studio 2008. I am using Webmethod to communicate from/to the server with the client. Data can be queried and returned in small amount, but when I try get a relatively large amount of data, it's returning me a Server 500 error. My data is 226561 character long, so it's not that large, but it's relatively larger than my other working testing set, which are about 10k character long.
JavaScript: PageMethods.my_func("context", success); function success(result, userContext, methodName) {
[code]....
Is there anything I can change to increase WebMethod returned string length limit? Is there even a length limit or is it some other problem I could not see?
I have a xml file that should contain a apostrophe in one of the nodes name. Now as far as I can see it can't be done but put a bit of light into this. So the node should look like this <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <name's> ... </name's> Now I'm sure that the xml is not correct, but how can I bypass this?
I have Visual Basic code going against a MS Access database. I am trying to create a Select query using parameters to filter records. One field is Location which is a loaded combo box. The user can select "Catering Hall" which is not a problem. But if they chose "Paddock's Restaurant" I get a syntax error. I tried putting a double apostrophe on either side of the query but that doesn't work.
[Code]...
how to get around this as the database record is "Paddock's Resaurant".
How do I query a DataTable where a value has an apostrophe in it? For example, my datatable has a lastname column and I want to search for the name "O'Bryan", how would I do it? With an SQL query I would just use a parameter & it would take care of the apostrophe automatically. Is there a way to use parameters with a DataTable?
I am using VB 2008 express and would like to know, If i can Replace a string inside of Javascript on page loaded into axWebBrowser so i can then execScript that function. The specific string i wish to replace is "_new" to "_self" this is so when i call the function it will load in the same page instead of popping into a new web browser. Also, is there a way I can just insert my own javascript function in the DOM as well?
In .NET 3.5, I have a Winform with a combobox in it. The datya comes from a DB2 mainframe DB. The problem is that we have a character that is not the real apostrophe. Pasted from Word I'd guess. But in our combobox, it is not diplayed correctly. It shows a question mark "?" instead.
I am having an issue with the SQLCommand query update handling apostrophes. I have a gridview that accepts edited text which might have apostrophes and other such accent characters.The UPDATE keeps throwing errors on the apostrophes in the text entered causing the SQL UPDATE to fail.
Here is the code: Dim lbl1 As Label = GridView3.Rows(e.RowIndex).Cells(0).FindControl("Label1") IDVal = lbl1.Text
I have a form which has a combobox (cmbactiveproj) and a textbox (txtProjnameupdt). By selecting any value on the combobox the textbox changes accordingly. The user has an option to change the txtProjnameupdt.text and save.
Note: the text stored in txtProjnameupdt is part of the value in the combobox.Then I refresh the combobox by calling the datasource;
This reflects and changes that have been made i.e., the combobox gets refreshed.and the change made can be seen on the combobox, and selected by the code below.
But when the user inserts an 'apostrophe' in the txtprojnameupdt.Text and save. It all works fine... But the selectedindex on the cmbactiveproj is BLANK.It ONLY happens when an apostrophe is used if I dont use an apostrophe it works fine..
How can I change the highlighted code to accept an apostrophe.. Presently, it gives an error: Unclosed quotation mark after the characetr string ;'Test Project''. Incorrect syntax near 'Test Project''.
