Posting Data To SQL?
Dec 19, 2011
I am currently working on a form that performs several calculations and then submits it to a sql server. I was able to post test data to SQL when using command.CommandText = "<SQL insert statement, inserted values 'test, 5'>" followed by command.ExecuteNonQuery(). But now when i try to submit data using variables i get an "A first chance exception of type System.Data.SqlClient.SqlException' occurred in System.Data.dll"I am not a programmer, so sorry if my code looks a bit rudimentary...

Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]

Background: My VB .Net application is a back-end solution that works with a proprietary Linux-based middle-ware messaging architecture developed by our company. My application references to the middle-ware DLLs, obtains connectivity, and subscribes to specific broadcasts with the middle-ware. When the broadcasts are received, it handles processes them and inserts/updates certain tables in a database. To do so, it has specific notification classes to handle each type of broadcast. These classes adhere to the inheritance model imposed by the middle-ware DLLs.

I understand how to post a value back to a standard asp.net page and how to then use that value at the serverside:
Request.Form("id_of_posted_value_goes_here")
How do I do the same in a webservice (asmx)? I can't use the line above because it says:
Name 'Request' is not declared.

I'm using Visual Studio 2005 and ASP. NET 2.0 with this program. This is written in VB.net
Right now, we've got a Gridview that is embedded and databound into another gridview. The 2nd Gridview is hidden by default and expanded by the user. Within the 2nd gridview are several DropDownLists. The problem is that these DropDownLists are not firing the OnSelectedIndexChanged functon nor AutoPostback whenever I change the selecteditem.[code]...

I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?

I have a form which contains a fairly large number of values. I am currently submitting with a POST method, but I wish to convert this to do it with jQuery via AJAX. I have been experimenting with converting my code-behind "save to database" function into a Web Method. I am using a two-step function method, firstly preparing all the variables from Request.Form("parameterName") and then passing them all into a "saveData" function as follows:
[Code]...
From the post mentioned above, I can see I can send this string, but how do I process it server-side when recieved? The article implied that HttpContext.Current.Request.Form("parameterName") should work, but it doesn't... I'm guessing because I need to access it from the txtQuery variable..

I am generating ListItems for a CheckBoxList control in ASP, but when I do something like the following:
...
Dim newListItem As ListItem = New ListItem("RoleName")
newListItem.Attributes.Add("style", "color:blue;")
CheckBoxListControlToFill.Items.Add(newListItem)
...
"RoleName" is maintained from post back to post back, but my style tag is dropped after the first post back. If I want to keep any attribute like this, do I need to re-add it every post back?

I'm having some issues with an Invalid Viewstate error and I can understand why it's happening but I don't know how to fix it so I'm hoping someone can help.
I have a page which is similar to this /story/?id=123 but I'm using a different page to Server.Transfer to this page.
So I've set up /info to Server.TransferRequest("/story/?id=123") and it works fine until the page does a postback to itself.
We have a login form on this page which simply reloads the page but when it does it seems to add /?id=123 onto the end of the URL so it ends up like this /info/?id=123 thus causing an Invalid Viewstate error.
I've already tried adding EnableViewStateMac="false" - this fixes the error but it doesn't log the user in as expected so it does not give the required result.
Is there a better way to redirect to my page other than Server.TransferRequest but still keeping the nice URL? - I don't want to response.redirect if I can avoid it.

Upon a javascript button click, I'm using jquery to post to a url:
$(".optionClick").click(function () {
var caseOption = $(this).attr('title');
$.post("../tracking/RecordClick.aspx?page=gallery&item=" + caseOption);
});
On the page being called, I'm using the following vb.net code to retrieve the querystring variables and write them to a database:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]...
Each of the javascript blocks above worked locally as intended but failed in the same manner with multiple DB writes and Firebug "Aborted" status.If I call the url+querystring directly via the browser, everything works as expected. (Edit) Also tried using the full path url in the code above - no improvement.

I need assistance with posting lines from a text file (test scores) into an array. From there, I'll have to average the test scores, find the standard deviation (without using the built in function) and assign grades based on the test scores' deviation. I have already written the code for the user to search and upload a text file. And I should be able to do the standard deviation of the array, if someone can help give me an example of how to send the text file to array and average the lines of the array without using the built in math functions.

I'm having an issue with trying to use VB.NET and the WebRequest object to post some cXML text and an attachment.I believe I am formatting the text of the data I wish to post correctly, as it matches samples Ariba has supplied. What I am uncertain of is if I am correctly using the WebRequest object to do the posting.I am setting the Method as "POST" and the ContentType as "multipart/mixed".I can successfully post cXML (using a ContentType of "text/xml") The message I get back from Ariba is "The document could not be parsed: Missing start boundary [ANCLS-741552]", however, as the following code shows, there is a start boundary.I have removed some proprietary data and replaced it with "...". Following the MIME text, I have included the relevant VB.NET code I am using.[code]

I have a problem reading data from an RFID-reader. I connect to the reader by tcp and wait for DataAvailable to be true, then reading the data until I got a end of data character. Then I just go back and waiting for a new DataAvailable. This is done in a own thread for the function.
There seems to be some kind of timeout, If I don't got any data in a couple of minutes, then it just sits there in the do/loop waiting for DataAvailable. I hold the card to the RFID reader, it beeps, but there is no data available. I don't get any exeptions, and the information says that the clientsocket is still connected. Are there anything more I can check?
If I put the card to the reader in a minute-interval it seems as this will never occur. So 2-3 minutes idle:ing seems to do this.
Here are my code to read data from the socket, I have taken away some irrelevant code:
Sub test(ByVal ip As String, ByVal port As Integer)
' this sub is meant to run forever
