Write The Data Back To The Database?

I get the following error:"Update unable to find TableMapping['Product'] or DataTable 'Product'."

Any ideas what is wrong. Code is as follows:

Update Dataset Back To Remote Database Via Web Service
Jul 14, 2011I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)

View 1 Replies.net Xml To Dataset Back To Xml?
Jul 28, 2009I recieve a failry complex XML from a web service (30+ tables; with nesting). I need to be able to look a this data; make mods and then pass it back (still well formed per xsd) to the web site. I am able to parse it both natively in XML and by putting it into a dataset. I am more comfortable working in a dataset so thought the best approach for me would be to take the XML to a dataset dsOrder.ReadXml(XMLreader) (also tried with inferschema switch) work with it as required; then using _newXML_str = dsOrder.GetXml
put the dataseet back into xml. This almost works, but the XML while well formed does not adhere to the schema. In particular, it appears that all the simple types for a table are put ahead of the complex types (even thoguh the schema wants some of these items intermixed), so when sent back to the web site, it complains about the order of the tags.
is there a way to get the xml from dataset command to form an xml that will ahdere to the schema? I tried using the available xsd to influence this process but it either doesn't work or I did not know how to apply it properly. If someone has a suggestion for this application I would appreciate comments and any detailed samples that come to hand. I am working in vss 2008; framework 2.0; and use vb.net.

Javascript - Writing Back A Function Through Response.Write()?
Apr 12, 2012I am trying to return a javascript function using response.write in an aspx page. The problem is that the function i am returning has lots of quotes and they are conflicting with the repsonse.write syntax. Here is a sample code:
Response.Write(" If hello.StartsWith("H", StringComparison.InvariantCultureIgnoreCase) OrElse hello.StartsWith("W", System.StringComparison.InvariantCultureIgnoreCase) Then")
This is giving me a problem as the quotes inside are cutting off the response early. Is there a better way to do this?

NetworkStream.Write() Slow When Writing Back Received Data To Browser?
Apr 13, 2012I am building a simple proxy in server vb.NET and so far it has been successful, but then whenever i receive data from the internet and write it back to my browser's network stream using NetworkStream.Write the received data tends to come up slowly to my browser due to reasons i do not know of.

Read Text File / Search For String Then Add To Line And Write Back?
Nov 18, 2010I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:

After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.

Mar 4, 2011I am using a dataset control on a form to store and read data from XML files. So far I use the following to write info.
VB
Dim drow As Data.DataRow = DataSet1.Tables("item").NewRow
drow("path") = strFilePath
drow("id") = strCreationDate
[Code]..
The problem is I need to APPEND data to the same file. What I do now results in the same file being overwritten. I am dealing with large amounts of data, so I would love a way to append to the file without the need to re-read it with each save.code lines 1-4 are in a loop so that at one time, they add a few hundred rows to the DataSet. After that loop is when the save takes place. However, I want to run that loop again and again every so often to update that same file.

Deserializing Data Back To A Dataset But Data Is Not Persisted To DB
Jul 27, 2011I have a situation where I serialized data from a dataset to an xml file as a method of backup.I am trying to get the data deserialized back to the dataset.But for some reason, I cannot get the data to persist back to the DB.I don't receive any error messages either.The first chunk of code is the serialization code and the second chunk is the deserialization code.I can show that the deserialization back to the dataset is complete because this code in the 2nd block DataGridView2.DataSource = Movie_dbDataSet.movie_tb - displays the data in correct form all it is all there in the datagridview2.I call the update method but it does not get persisted back to the db.[code]
