I have a XPath expression that is supposed to return/get only one node out of the XML document. But it is getting more than the one. I don't understand why.
Code-behind:
Dim xmlNameTbl As XmlNameTable = rootDoc.NameTable
Dim xmlNS As XmlNamespaceManager = New XmlNamespaceManager(xmlNameTbl)
xmlNS.AddNamespace("asp", "http://test.com/asp")

this list has tried to mix numerical variable, such as 1, 2,3 within an xpath expression. [code] For some reason, item_ number_ first and item_number_last appear to have no value in the above code snippet, when they do have values they get printed as in the [code]Could anyone please give me some hints on what to modify here to make the numerical data be able to mix within my xpath?
View 2 RepliesI have an XElement and an XPath expression that selects a node from it. It works fine in the original program that I wrote it in but doesnt work if I paste it to another program. I've checked the references and import statements.
I think the problem might be that the original program had the code within the class of a wpf window while it was moved to a abstract class where it doesnt work.[code...]

View 1 RepliesI am using parameters in my code to update records in an access database.
One of the fields I am using in my sql Query Update statement is the ID field and it is causing this error -
Data type mismatch in criteria expression.
I have isolated the error and it occurs with the ID field in the Update query.
The DataType for the ID Field in Access is AutoNumber, Field Size is Long Integer and New Values is Increment.
In my code I have declared the Data Type as Integer.
Is there an obvious mistake in my code?

I'm having trouble trying to find the best method to do what I'm needing.
I'm thinking of using a regular expression to read a .txt file and parse out the MAC id information that will be in the text file. I was wondering if there was an easier way to do it or what the best way to do this is.
readall(textfile)
macID = d{1, 4}.d{1, 4}.d{1, 4}
totalMacInfo = all the macs in the text file?
If you guys have an alternative solution or a good way to write out the code I am open to suggestions. Not exactly sure how best to mix the expression into reading a txt file to get the data i need.
I have a regular expression that I use to grab data between two sets of id's for example:
<CLASSCOD>70</CLASSCOD>
The regular expression I use is:
(?<=<CLASSCOD>)(?:[^<]|<(?!/CLASSCOD))*
Which works in most case but when I have a single value like this
<CLASSCOD>N</CLASSCOD>
It says there are no matches.
The whole data string looks like this :
<STATUS>PRESOL</STATUS>
<DATE>0601</DATE>
<YEAR>11</YEAR>
<AGENCY>Department of the Interior</AGENCY>
<OFFICE>Bureau of Indian Affairs</OFFICE>

Probably a simple problem but I'm failing to see how or why it's happening.
The error message I'm getting is Data type mismatch in criteria expression.
My coding is below:[code...]
The error is coming up when i'm filling the dataset, i've already figured that it works when the WHERE is removed.
So i'm assuming the mismatch must be from (VirtualLearningExercises.Level = '" & UserLevel). UserLevel is defined as a integer in vb and VirtualLearningExercises.Level is data type number on access.
I've had this problem many, many times. And it's always turned out to be a small typo or "" around an integer, but I just cannot find what's wrong with my SQL Statement this time! SELECT Card_ID FROM Payment WHERE Customer_ID = 12 AND Card_Number = 1231231231231231 The table and fields are named correctly (the table is actually a query).The only thing I can think of is the card number being too large, however it works fine in my INSERT INTO statement!All of the fields are formatted as their respective data types, ie. Integers are set to integer, not string.

While looking in the dataset designer for a database table I am doing in visual basic 2008 I found a line for expressions under the property menu for a specific column. I need to know the code that I would put in this expression line so that this column adds up the numbers I input into three other columns and displays that number in the column. I need it to automatically calculate this for each row in the database table.
