Forms :: Get The Message That The Local Database Is Empty But The Program Still Runs?
Dec 27, 2011
I'm having an issue with the startup of my build app with vb2010.Let me explain what the situation is at the moment.
I have a form and a splashscreen. I use the application events (startup event) to check if there is a network connection, if so the splashscreen will run and it will check if the database is available, if this is the case, it will copy the online database to the local ms access database.If the startup check of the network is false, it the user gets a message that there isn't any network available and the program will try to run normal, then when the user clicks the ok button of that message, it will check if the local database has any records. If so the splashscreen will run and the program starts normal (without copy the database, because there isn't any network available).The issue that I am having is, that when there isn't a network connection and the local database is empty, (I do get the message that the local database is empty), but the program still runs, while it should exit.Here is the code of the application event:
Protected Overrides Function OnInitialize(commandLineArgs As System.Collections.ObjectModel.ReadOnlyCollection(Of String)) As Boolean
Me.MinimumSplashScreenDisplayTime = 5000[code]......

I have a VB 2008 console application .NET 3.5 who handles large data tables in a SQL 2005/8 database. Sometimes when SQL server do not response as application expect. Then SQL Connection change status from open. I try to get the event of changed connection string before error occurs.
1 - SQL Connection status changes from open to another status
2 - When this event fires a fix sub routine or function starts and fix the sql connection
3 - Return back where SQL Connection was when status was affected by program.
My app is a large list of SQL Commands who runs in a class orginsed as a simple list of sqlcommands.When a SQL Connection fails I will start at the last point in the program after SQL Connection are open again.

What I am looking to do is write a VB.NET program, as a service that reports anything on client1 that I want (say the fact it is online) to a database on the internet, so I can look on management1 and see the online status of the machine (assuming management1 has a connection to the online database).
What is being reported doesn't matter, what I am looking at is a starting point to create a system like that. I have googled obviously and come up with nothing, I'd just like a "starting point" or some documentation to look at for creating something like this. The service doesn't look too difficult but the periodic reporting of online status or ANYTHING to any kind of database is not something I am sure how to deal with.
I already have setup a VBS that reports information to an ASP script that then places it in a database but I don't know how I would create say a "keep alive" connection for a vb.net service.

I have a program that is using API's to send mouse events and keyboard events to another application that is running. I need to know how to tell if there are any messages left to process for that window after I have click on a button or moved to the next field. I need to know this so I don't send any more mouse or keyboard events until it has finishing processing everything in its message queue. An example is that I click out of the key field and the form has to go out and read a client record. This may take a second or two, so I need to wait until the form is ready for more input.

I have a couple of modal popups on my page that hold checkboxes. The checkboxes are different items that can be added to a specific product. Some products, however, have all of one type of item assigned to them. I need a way to show a message in the modal when the modal is empty.
I have tried using a Label inside the modal that says "All features are currently associated with this product." But the label leaves a space in the modal when it's visibility is set to hidden and that was annoying so I ditched that idea.
What is a good way to have a hidden message that shows up when the modal is empty?
<asp:LinkButton ID="FeatureButton" runat="server">Feature</asp:LinkButton>
<asp:Panel ID="FeaturePanel" runat="server" CssClass="modalPopup"
Style="display:none">

I've got a grid view. I want it to say "you have nothing to show" if there are no details.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If GridView1.Rows.Count = 0 Then
[Code].....
However; it seems to be working backwards and showing the message when there is data to display in the gird view and continues to be a blank page when there is not data to display in the grid view.
I've tried a variety of combinations with the below IF statement below but no success.

I am using the EmailMessage to send email message(s) from my local computer. I am also using the SMTP server of my ISP and generally it works just fine. However, some of the emails are never delivered to the destination (bouncing emails) and i get "Mail Delivery failed: returning message to sender" How do i check if the message can be delivered rather than receive the "returning message to sender"? Should i check the destination email server? I have no idea from where to start actually.

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim name As String
Dim icn As String

I've almost completed my first VB.Net app which is a rewrite of an old vba app I wrote.The last part that I need to write is the timed events part. What I have in VBA is quite straightforward.Every 500ms the Timer event runs through, it checks if certain variables have been flagged and if so runs the relevent code? Code is nothing major, just updates a networked device.I've looked into timers in .net but it seems like there are various routes that I can go down.

I have made a program that has an intro screen, moving onto an activity select screen which acts as the main interface to get around the program. After creating the program and installing it on my computer, when I close the program from the activity select screen, using the "X" at the top right corner, the program continues to run under "processes" in the task manager.If I close the program from the intro screen though, it will close everything, including the processes. Is there anyway I can get the same to happen with the game select screen? I can make it work by putting my own "End" button on the form, but id prefer to be able to do it with forms own close button.

I created a program in MS Visual Web Developer 2010. It has a form that simply launches a script that manipulates a database. The project lives in several files and they are all inherited so they see each other and it accesses a MSSQL Express DB on one of our servers.
When I F5-Run the project locally on my PC it works fabulously. When I copy it to a web-enabled (application) folder on the server it executes but almost my very first line of code fails with this error[code]...

I would like to know if there is a way to see how long a program runs. I have one that takes a very long time to run, which is not the problem. I start it and go to bed or leave for the day. When I come back it has finished. I do know it takes hours. Is there a way to find out how long it does take to run give or take a couple of minutes?
