I'm developing a system and the system contains an update function to update the DB. I have performed all the coding but have some minor problem in my SQL Statement and I'm unable to detect the SQL Statement Error. Hope someone could rectify the problem.
[Code]...
With the following SQL " Dim Query As String = "UPDATE JobName_tbl SET [JobDate]=@NewDATE, JobAddress=@Newaddress Where JobID=@ID"
nothing happens nothing gets updated nor do I get an error.But as soon as I remove the [JobDate]=@NewDATE, it works fine.
Here is my code:
Public Sub UpdateAddress(ByVal JobID As Integer, ByVal JobUpdate As String, ByVal NewDate As Date)
Try
Dim Query As String = "UPDATE JobName_tbl SET [JobDate]=@NewDATE, JobAddress=@Newaddress Where JobID=@ID"
Dim DBcon As New DBConnection.Connection

I'm running Microsoft Visual Studio 2010 SP1 and SQL Server 2008 R2 and I'm using vb.net coding. Any other information that you need to know, just ask.I've got a form in a master/ details setup that has one table in details view in the top half of a split container, and another table in a dgv in the bottom half of the container. Everything is working well except for one value. My dueDate value always reverts back to the date set when the record was made, which is the default value put in when a new record is made. It doesn't give me any errors to work off of, and I've even went and coded the update by hand with this code:
Dim Num, Contract, ID, Receive, Due, Notes, Inspect, SO, PO, Entry As String
Num = Order_NumToolStripTextBox.Text
Contract = Order_ContractTextBox.Text
[code]....
All that happens when I hit save is my due date will revert back to the old due date. I have no clue what would/could cause this. I've went through to see if anything that would store the original dueDate (from a check I set up in my coding) is coded somewhere it shouldn't be, but all it does is make the check that something had changed while on the form. it takes an array of all my text boxes and checks it with an array made before leaving the form. Nowhere else is the original dueDate saved.
I am using VB 2005 and the following code returns an error: No value given for one or more parameters. I swear I've done this before without any problems but I can't find my original code.[code]I tested the value of oldid which is set earlier and it does have a value.

I'm trying to update my wallpaper with VB.NET and it's not working. Weird thing is, this same code works fine on my other machines (same OSes, Win XP Pro SP3). My code grabs a random picture then passes it to the SetWallpaper function:

Public Shared Function SystemParametersInfo(ByVal uiAction As UInteger, ByVal uiParam As UInteger, ByVal pvParam As System.IntPtr, ByVal fWinIni As UInteger) As <System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)> Boolean

I need to select some user datagridview settings (such as column width, column visible, etc.) from my database. Then I run a loop to change those settings. If any settings are changed I need to update the database. For some reason I can't get the code below to update anything. The code throws no errors when it executes, but when I check the database for the updates nothing is changed.
Public Sub pubsub_UpdateUserSettings(ByVal FormName As String, ByVal dgv As DataGridView, ByVal MethodID As Integer)
Dim adt As New SqlDataAdapter
Dim cmd As SqlCommand
Dim cmd2 As SqlCommand

I have my application set up with ClickOnce. It has been successfully published to my web site. I don't have updates performed automatically but on demand. I have a button that the user can click if they want to check if an update is available and install the update if it is. Here's the
[Code]...
After clicking the button a message box appears and says, "Update is available for download" as you would expect but after clicking the ok on the message box my application goes into a not responding state and I have to close it with the task manager. The application builds successfully and I have a reference for System.Deployment added to the project. Everything in my application works fine as long as I don't try to do an update. Any suggestions on what I should check or do? It should actually say "no updates are available for download" since the version of the program that is being used is the most current version.
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?
I want to show in my form, something to show the user that the program is working just wrote a Label, but Visual Basic Freeze during the process and the label it can not seen and there is not signal to know that the application is working.

But the textbox itself remains blank and I'm stumped.
View 1 RepliesI have an application that opens up Excel, reads some information, then closes Excel. I developed this application using Microsoft Office XP 2007. A few weeks ago, my company upgraded to Microsoft Office 2010. The applications still works fine, but I can not compile in VS 2008 anymore. I get the error message: "Error 3 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'."

I'm using fileopen() function to open the file, after doing all the works I'm using fileclose() to close the file. But when I access the file again it returns already the file is opened by another process.
Sample:
Dim intFile As Integer = FreeFile()
FileOpen(intFile, mstrFilename, OpenMode.Binary, OpenAccess.Read, OpenShare.LockWrite)
FileClose(intFile)
Loading another form increases the memory usage of the application and after closing is not combing back to normal? dispose function at formclosed event is not doing that
View 12 RepliesI have a form that displays a graph. From the appropriate toobar button click frmGraph.show is called and it works. But when I call it from the assigned F6 function key the graph hardly ever displays. Sometimes it does display properly, sometime it flickers a one time display of the graph then it's gone, but mostly the form just draws the background but no graph. In debugging this i discoverd that putting a message box just before the call to frmGraph.show the graph will display properly everytime after i click ok in the messagebox. Anyone know how to cure this or at least a workaround that doesn't involve displaying the messagebox? This is the code with the messagebox("here") just above the call.
