Asp.net - Update Sql Command Not Executing Correctly From Vb Code
Dec 5, 2011
In my application, I have a call for an update to a table on my database. I know that it is executing because I get a 1 returned when checking the number of rows affected but when I look on the DB the value is not updated - I have refreshed and still no update. Here is the code, taskgrp_template is type bit and taskgrp_id is type integer. Id is also set to the correct value, as the result of my tracepoint - results listed below code.
mycmd.CommandText = "UPDATE p2_taskgroups SET TASKGRP_template = 1 WHERE TASKGRP_ID =" & id
rowsChecked = mycmd.ExecuteNonQuery()
Tracepoint result: the value of id is 55 and the value of templateCheck is 14 the number of rows affected was 1

I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.

I am using VS 2010 (.NET 4.0). I am trying to use the psexec command in VB to get a response back from the server. I am able to do this with other commands, however, psexec doesn't seem to send the output back, the program just hangs.
Code:
Dim Proc As New System.Diagnostics.Process
Proc.StartInfo = New ProcessStartInfo("cmd")
Proc.StartInfo.Arguments = "/k psexec \SERVER cmd /k iisapp"

Alright, so here's command I'm currently running. Upon executing, a command prompt apprears until the command is finished.
Is there any way to hide the command prompt?
Process.Start(
"\path_to_exeTesting.exe ",

I have been making a text based noughts and crosses game and trying to convert an alpha grid reference into a number to run the logic sequence that decides whether the an input is valid. I am using the asc command to convert but it just keeps putting up the error: Conversion from string "a" to type 'Double' is not valid, when it reaches the line If (Asc(Left(choice, 1)) >= 65 And Asc(Left(choice, 1)) <= 67) Or (Asc(Left(choice, 1)) >= 97 And Asc(Left(choice, 1) <= 97))Choice is the input and has already been checked for length, whether it contains an alpha and numeric input (and where they are) and whether the numeric value is valid.

I'm trying to create a program that does the following:Executes the following command line string (wmic /node:computername bios get serialnumber)Prompts user for the "node" entry Displays the resulting serial number in a dialog box I'm a bit of a noob at this (I haven't coded anything in VB since early 2000s) so I'm at a bit of a loss where to start. I plan on including some functions to submit the node entry and the resulting serial number to a database in the future for archiving as well.

I'm writing a command-line application in .Net. The app itself is fairly simple, but it has to connect synchronously to a web-service, which in turn has to connect to a Oracle database, and those pieces are fond of taking their time.
Is there a straightforward way (without dividing my app exe in two) to continue executing but nonetheless yield execution to the command prompt?
It's Windows, so no "&". Also, I cannot use cmd.exe's "start" cmdlet.

I am using VB.Net 2008 and ADO.Net to do a Batch Update to our Oracle database. The updates are working, but there is a trigger on the table before the row is updated to enforce a member's termination termination date. So if I was trying to set the termination date (via the batch update) to 31-Jan-2010 but the member had a claim that was processed on 2-Feb-2010 the trigger would force the termination date to be 2-Feb-2010. However, the trigger is NOT executing when the batch update runs?Is there any Oracle DB Admin option that would disable Triggers on Batch Update?

I'm facing a problem while updating data in a database through datagridview. I'm changing the cells using a for loop and then updating db using below code. All data rows get updated but 1 (the last one).
Here is the code I'm using :To load data:
ds = New DataSet

I use the following statement to position which row to update;
Dim salonToUpdate = (From r In db.Salons _
Where r.StoreID = storeID _
Select r).Single()
If fileDate = #1/1/1900# OrElse fileDate = Nothing Then
SalonToUpdate.LastDownLoadDate = TableDate
[Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace:
exec sp_executesql N'UPDATE [dbo].[Salons]
SET [LastDownLoadDate] = @p0
WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000'
Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?

Here's my code
Dim suppQuery As String = "SELECT [Supplier ID],[Company],[Last Name],[First Name],[Email Address],[Mobile Phone],[Office Phone],[Address],[City],[ZIP/Postal Code],[Notes] FROM [Suppliers]"
Dim dsSupp As New DataSet
Dim daSupp As New OleDbDataAdapter(suppQuery, cnPharma)
[CODE]...
It errors on the da.Update line and by the way if it helps, the text fields are a product of datarowview. that is when you select an item on the listbox the details of that appears on the text fields. and my goal is i could edit those text fields and save them.

I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
Here is my code:
<div id="divFileInputs" runat="server">
<input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em"
onfocus="AddFileInput()" class="textbox" /></div>
[code]....
When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.

I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command
