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
[code].....
This code seems to be accurate when comparing to the many examples that are similar on different forums and I would think it should work:
Dim pC As New Process
pC.StartInfo.CreateNoWindow = True
pC.StartInfo.RedirectStandardOutput = True[code]....
When I remove the pC.BeginOutputReadLine() command, the application continues to function, but nothing is added to lbOutput.
With the pC.BeginOutputReadLine() command, it gives the error "vshost.exe has stopped working"
Either way, my batch file does what its supposed to do. Any one have any ideas what I am doing wrong with the process?
I have a VB windows Form project that connects to several DataTables in an Access DB. On my form I have several textboxes, comboboxes and datetimepickers that are bound to those sources. With one table in particular when I try to update the tableadapter after editing one of the textboxes the update method fails. No exceptions are thrown, but the update method returns a zero value and the data is not updated. The update will work when just the comboboxes or datetimepickers are edited, but as soon as a textbox is edited also, update will not work.
Other DataTables within the project are set up in the same manner but are not having update issues. I can't figure out what about this one particular table is causing an issue. Can anyone give me any thoughts on where or what to troubleshoot?
I'm using .BeginConnect with an AsyncCallBack and for some odd reason when I try to add a string to a textbox using the sub below, from a routine within the socket, it just does not work. It's not stating an invoke is required either.Private Delegate Sub DelegateAddText(ByRef theText As String, ByRef AddReturn As Boolean, ByRef AddPrefix As Boolean) Public Sub AddText(ByRef theText As String, ByRef AddReturn As Boolean, ByRef AddPrefix As Boolean)
[Code]...
as a side note which would be more efficient ... Indexing sockets and passing indexes through routines, or spawning classes. I realize spawning may use more memory but is it faster than indexing?
I have a very simple StopWatch application in Silverlight. I have the following private properties in my MainPage class: _StopPressed (bool), _TimeStart, _Elapsed (string). I also have a "Start" and "Stop" button. The "Start" button calls a method called UpdateTime that constantly updates _ElapsedTime until _StopPressed is true. When I originally wrote it, UpdateTime would block the UI so I couldn't press the Stop button, so I updated my code to use System.Threading.ThreadPool.QueueUserWorkItem with my UpdateTime method so that it updates _Elapsed on a background thread. That works great at updating the value.However, if I try to set the .Text value of my TextBlock from within UpdateTime(), I get an UnauthorizedAccessException that has to do with one thread accessing the data in another thread.What do I need to do to avoid getting this exception and appropriately update the UI without blocking it?

View 1 RepliesI 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 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.

how to get around this as the database record is "Paddock's Resaurant".

View 5 RepliesHow 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?

View 1 RepliesI have an html string that is dynamically created server side.

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.
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;
Me.QryactiveprojectsTableAdapter.Fill(Me.Projstatus.qryactiveprojects)
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.
cmbactiveproj.SelectedIndex = cmbactiveproj.FindStringExact(txtprojnameupdt.Text)
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..
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 ?

View 2 RepliesI 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 '='
How to create a function that replace the apostrophe (') into empty string?
View 3 RepliesI am trying to filter fields in a table that contain percent (%) and apostrophe (') characters. I kow that to filter an apostrophe you need to add another apostrophe (''). However, when a text contains the percent (%) character in combination with an apostrophe (') character, an exception is thrown. Also, when using the % character in a filter string, it will be function as an "*" (fields starting or ending with). I need the % to be considered as a character whenever the % makes part of a string in the field. How can I address these issues? [code]

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.

The data was being read from a Gridview which had the html encoding. The solution was the following...
Dim Sht_Text As String = HttpUtility.HtmlDecode(row.Cells.Item(0).Text)
I am trying to prevent from having to escape apostrophes and other special characters in my string variables by using a parameterized query with an OleDbConnection. I have all of the parameters in the same order, the insert is working, it just does not maintain the characters. I keep getting those pesky html codes. I am trying to insert into an Access db from a web pages. As I mentioned, its working, just not the special characters.
Here's the code:
Dim pConn As New OleDb.OleDbConnection pConn = New OleDbConnection(cb.ConnectionString)
Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (?, ?, ?, ?, ?, ?)"
[code]....
jp and en records already existed, the insert of fr record pushes the html codes for the small circle which represents the degree symbol. Happens for all other special characters as well.

Unfortunately, the line ddlBuildAddr.SelectedIndex = addressId is failing. Looking at this line through the debugger, the SelectedIndex goes to -1, while addressId goes to 2. What gives? Why would the assignment operator flatout not work?
My understanding of assert.fail was that if the line is executed, the test will fail.owever, I have found an instance where the assert.fail is executed, but the test passes.If the Assert.Fail statement is within a try block, the test will ALWAYS pass, even if the code execution executes the assert.fail. For example, the following test will always pass, even if the sub fails to throw an exception.
