I have the following code. I am loading the xml file, it's fine. When get into my loop and try to read the line I get unhadled exception and the following error
'Part ID="1"/SalesPrices/OrderPrice/GrosscostsAPiece' has an invalid token.
I have discovered that the reader is not liking the Part ID="1" part. How to overcome this problem considering the xml will always have that element as it is. Need to extract the value in the GrosscostsAPiece element.
document.Load(xmlFile)
for Each element As XmlElement In document.SelectNodes("document/body/Parts")
arr(1) = element.SelectSingleNode("Part ID="""1"""/SalesPrices/OrderPrice/GrosscostsAPiece").InnerText

I use an XPathNavigator Select to get a node iterator in the code below and get an invalid token error. If I take out the @contract I do not get an error. I then have to use MoveToAttribute, which works, but shouldn't be needed. Why do I get an error when the @ syntax is valid XPath?
I am currently trying to write a little wrapper around post-review to automatically post however this function fails when it comes to Dim results As String = sOut.ReadToEnd() and I can;t suss out why,
Edit: It doesn't produce an error it just seems to go into ReadToEnd() never to return
Function postReview() As String Dim psi As ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd.exe") psi.UseShellExecute = False
[code]....
Further Info: The actual command is working as I can see it posting to Review Board. But it just seems to get stuck in a loop while waiting on the Stream to complete. I have tried with Read and Readline with no luck?
There are already multiple threads about this, but i don't have the knowledge about the different SQL databases/methods to make heads or tales from it.I am using an OleDbDataCommand, an OleDbDataReader and the following code
Dim Query2 As OleDb.OleDbCommand Dim RetVal2 As OleDb.OleDbDataReader Query2 = New OleDb.OleDbCommand("Select [section], [title], [id] From " & DtSections & " Where [volume] = " & volu & " And [chapter] = " & chapter & "", AccessConn)

In a nutshell...I have developed a site in ASP.Net and VB.Net which allows a user to create an order and submit it to a SQL Server backend database.
When the order is placed...an xml file is also produced, showing the items that have been ordered...which is then loaded in to a program to update stock quantities.
The code I have is as follows:
Public Sub butSubmitOrder_Click(sender As Object, e As EventArgs) Handles butSubmitOrder.Click Dim sqlConn As New SqlConnection
I am not sure why this code doesn't work. I have follow according to the table field data and it I am still unable to get the SQL Datareader to work. I have checked the tables and all datafields, everything is correct. But I still am unable to read data from the database.
Dim connectionString = ConfigurationManager.ConnectionStrings("CleanOneConnectionString").ConnectionString Dim myConn As New SqlConnection(connectionString) myConn.Open() Dim cmd = "Select * from [Member] where Email = @Email" Dim myCmd As New SqlCommand(cmd, myConn) [Code] .....
Invalid attempt to call Read when reader is closed and sometimes Invalid attempt to call MetaData when reader is closed when attempting to read from a sqldatareader object. What I want is to list groups in listview. The last column is "Total Numbers".[code]...
It works ok for the first row but after that the first error generates. I don't want to include the COUNT function in the main sql cos then i would be required to group the rest fields (there are 9 of them totally). I tried MARS but it don't work at all in my connection which is like
"Invalid attempt to call Read when reader is closed." is returned when trying to use a SqlDataReader in a Thread or BackgroundWorker (Do While z.rdr.Read() in the bold sections - I know this code does the same thing twice....). I have looked at a few forum posts but I did not find a method to keep the SqlDataReader open when passing the arguments. How do I thread the SqlDataReader loop?
When I run my application the following code prompts an error. Ideally, I want to populate the TxtOracleNo with a value read from another table on my form based on certain conditions i.e., prac_no, prac_eid and pay_method is the same in both tables then populate the Oracle No on TxtOracleNo text box.
The error given is "Invalid attempt to read when no data is present"
The function is shown below Private Sub Oracleview() 'Open the database. 'Delete any existing record Dim cmd As New SqlCommand Dim conn As SqlConnection = GetDbConnection() [Code] .....
I checked that data in the database and it is available in both tables. Probably, the problem is where I call the function. Presently, I call it on loadform.
My console errors out when I enter anything other than a number or operators in the designated (input). I stink at this stuff but I have been t this for about 8 hrs. still not there. I have included a text file for the task at hand
I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing) Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)
How am i going to make a token with this string"The quick brown fox jumps over the lazy dog" that its output would be:
the quick brown fox jumps over the lazy dog
Token:9
The token is equal to the number of words. For every word entered, to identify it as a word is a space, which means that the space serves as a counter for the token and the words entered are printed in that kind of output.
I have an error that is during the query to a database ExecuteReader 'phase' of my program, i am assigning an .OleDbDataReader to a variable RetVal and then, i am giving this RetVal = Query.ExecuteReader, and then in the while the query is being read loop(While RetVal.Read) i am getting an error in runtime that is "Invalid attempt to call Read when reader is closed." I know this means i have to open the reader, but i don't know how to do this, as i have been using this process for a few weeks and haven't had this error pop up. (and i have managed to use the while loop)If you're not living on the edge, you're taking up too much room
I am using The Facebook-C#-Sdk v5.0.3 to create a non-canvas webforms app in vb.net and i am having trouble exchanging the returned facebook code for the access_token. Does anyone have an example (C# or vb.net) that I can look at
Forgive me if this has already been covered in a previous post. I am considering using VB.net for a project but need to know before I dive in if it can perform this particular functionality. The application I wish to develop would need to be able to create html and email templates using variable tokens - what I mean is that users would need to be able to insert into their html or email template previously assigned variables that would send dynamically generated text from the database - so, for example, they could write in their template {title}, or {firstname} {lastname} which would then be replaced by the data from the db.
i have been visual basic 2008 to create a program which contains a lot of images nearly 1000 my computer is running vista with a 2GB RAM and over 5GB of space free..i keep getting a message about ~"Token Endelement would result in an invalid XML file"~ it then offers me to "save as" it then becomes very slow and will take a while to allow me to get another "token endelement message".i also get one about "exception of type 'system. outofmemory exception' was thrown" the last message, after getting several of the above is "cannot be completed"..i will put a link of my program files (not the images) and would ask for any help as soon as possible as this would save me quite a bit of data i can't remember when i last saved it!
I have a asp.net website. The asp.net website connects to a wcf service. The wcf service is using a sts(security token service) with custom username/password authentication. The asp.net page has a simple username and password login form. Now I'd like to implement a "remember me" function. At the moment I have two solutions: Saving the entered user and password on the asp.net server and set a cookie with an ID. Saving the STS token on the asp.net server and renew it if needed. What is the more secure solution? Do you have any other ideas?
I'm trying to write code in .NET 2.0 to change the time zone - long story short its toautomate server deployment. I'm having a problem adding the SE_TIME_ZONE_NAME privilege I found code online to add the SE_SHUTDOWN_NAME privilege which I adapted into the following code:

I'm getting Invalid column name 'CHARLES'. Invalid column name 'CHARLYN'. Invalid column name 'SMITH'.what's wrong with my code, it's been a long time since I used SQL dataset. I'm into LINQ but I'm having problems with this kind of LINQ query so I'm reverting to SQL dataset.here's my code:

Ok. So I have a form, a textbox, and a RichTextBox. In the RTB, there is justsomemiscellaneoustext. In the textbox, it says "Save "Test"". When I press Button1, I want my program to parse the text in the textbox, find "Save", and realize that means to save the text in the RTB to a txt file with the name "Test" (the text next to 'save' in quotes).
I have a couple quick questions with the program that I am doing. This program is a hilo program and here are my remaining issues...
1. When I click the high or low button in my program it does not make changes to my token (I want the default tokens to be 100 and added 100 to the text property of my textbox so want to make sure I did that right)
2. In my program it only shows 13 possibilities but want to have the ability to add more
3. I also would like to change 1 to ace, 11 to jack, 12 to queen, and 13 to king and would like to get some assistance with that as well
When I try to call a [Java] web service from .NET, I am getting what appears to be a security credentials issue. CWWSS5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.Is it even picking up the credentials that I am trying to pass? At this point, I just want to make contact with the web service and get access. In my example, ServiceReference1 is a generated Web proxy class.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim myLocateProfileBySourceSystemId As New ServiceReference1.locateProfileBySourceSystemId
We're in a strange situation with a legacy winforms VB.NET 1.1 application using ASMX web services. Trying to send a user Token from a WindowsIdentity object as a parameter to a WebMethod. I will be adding a 'HACK: comment. System.Security.Principal.WindowsIdentity.GetCurrent().Token
The token is of type IntPtr, the first problem is the WSDL being generated doesn't support IntPtr with the error of 'unsupported type'I'm aware this is a big WTF question and sounds insecure, so any simple helpful alternatives are welcome but there are a lot of constraints on how we can change this system, including complications with the hosting environment. So I would just like to get our piece of data over to the web service to save a lot of other headaches.
where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.
Private Sub GetReport() Try Dim hawbs As String = String.Empty[code]....
The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.
