Temporarily Saving Data To Localhost?
May 24, 2012
how to temporarily save the user input to the pc he is using then save to another pc in the network later. Our LAN sometimes disconnect or there maybe power interruptions and I don't want that the input of the user disappear due to disconnection or power interruption. What is the easiest way to accomplish this?
Here's what I'm working so far. The data saves to another pc.
Imports System.Data.SqlClient
Public Class formGrammarI_Page01to04
Dim db As New EPTR_DataDataContext

I created a database (.mdf) file. I added data to it after running the program in debug mode. When I closed it and opened it up again, the data I got was stored and loaded again.I closed my whole Visual Basic Express program. When I opened it up again, all the data had disappeared.
Can you tell me what I am doing wrong with the program? I can't get queries to work either. It worked when I used the NOrthwind dataset this past weekend but it is not working when I use my own or empty dataset.

I am working on a database for a program. I used the .mdf file, created a table, and tried to store data in it.I did not build the program yet. I am still using it on a test drive or debug mode.I added three records to the database.I closed the program for 10 minutes and went back to writing code for it.When I opened up the program again, the database only showed that I had one record.This happened before and after I wrote other code for my program.I only started having the problem today?Is it possible that there is not enough room in the database to store all the records? The variable sizes for 3 of the fields are 400, 500,500, and 1000 and the other fields are like 50 each.All together there are 7 fields. I encountered the error after i had made one of the fields a look up field.In this field, basically I loaded categories stored in an extra files into the comboBox so users can select values without having to retype it.
Can you tell me what the error is and how I can fix it or what I am doing wrong in the program?How do I set up another table and query it to pull the values I want for the comboBox field?

I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data

I've made a WCF server and tested and debugged it only on localhost so far. I wanted to measure its LAN speed and couldn't get it to work. The client returned a EndPointNotFoundException. Below are the configurations I use on the client and server.[code]

I have made a "webserver" in vb.net the problem is that it seems like it's just listening to 127.0.0.1 (localhost) and not request that is sent over the internet. I have changed the listening adress to my public internet ip but it's still just listening to local requests.
Do someone have a source code with a working example of how this could be accomplished?
Dim address As IPAddress = IPAddress.Parse(79.138.xxx.xxx)
Dim EndPoint As IPEndPoint = New IPEndPoint(address,8082)
Dim ss As Socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
ss.Bind(EndPoint)
ss.Listen(20)

I'm interested in creating a simple localhost server that can serve dynamically generated data from a ListView into a formatted web page. I'd also like to "control" or otherwise have the program execute functions based on what links are clicked.I've been searching for solutions and it looks like it would be a fairly simple task but I'm not sure exactly what the best way to go about this would be.

When the web service is uploaded to the external server the desktop application has no problem finding and using the web service which access an Oracle DB to send/retrieve information. However, when I go to properties and change the 'Web Reference URL' of the Web Reference to localhost there seems to be a problem with communicating with the DB.

I have the MySQL connector dll for .net, but am having problems.
1) When I go to phpmyadmin on cpanel, it says the server is localhost. I am confused by which IP i am supposed to use to connect, as im pretty sure just localhost will not work.
2) When connected, can i use credidentials from an account already made to access the database, or do i need to use the admin credidentials?

I'm trying to see if a file I have loaded is located in the "Xampp-localhost-folder".
I'm loading a php-file-path into a textbox. After pressing a button the php file is loaded in a webbrowser. Now here's a problem. .PHP-files don't load local. The user needs to have at least Apache (MySQL/PHP/FileZilla FTP Server etc) installed so the page can be loaded via localhost.
The most important service that needs to be running is httpd.exe (Apache) or FileZillaServer.exe.
Public Function ProcessesRunning(ByVal ProcessName As String) As Integer
Try
Return Process.GetProcessesByName(ProcessName).GetUpperBound(0) + 1

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

I'm trying to hide 5 to 12 buttons on a form until a screenshot is saved to the clipboard. I have it set right now so the user clicks a button(btnSavePDF) and then whichever buttons are visible are made not visible. But I haven't a clue how to restore just those buttons. I'm trying to avoid restoring them all unless they were all originally visible.

I wrote the code and it runs through it perfectly, the problem is that it will only save it to the database temporarily. So once I close down visual studio for the night and come back to it what's been entered is gone. It's not a published program still in debug mode but I've not run into this before. I have another program I'm working on that I'm running purely in debug mode and it works flawlessly. The code between the two is the same cause I just copied it and changed the parameters. Any ideas? I'm using an sql mdf btw.I should clarify, don't know if it matters or not, that the DB that is working is in SQL server whereas the DB I'm having trouble with is a mdf that I added into the program.

I have an application which connects to a database, retrieves a username from a user's table and matches it against the username retrieved with System.Security.Principal.WindowsIdentity.GetCurrent.Name.On my localhost, everything works fine. The database exists on the development server but the application lies on my localhost. All of my authorization and authentication techniques are running smoothly.However, when I publish my application to the development server, I'm faced with the following error.Cannot open database requested in login 'databaseName'. Login fails.Login failed for user 'DevelopmentServerNameASPNET'.

Ihave created a system that allows an IT manager to log faults and assign them to available technicians, basically, you select a member of staff, a technician and describe the fault and then log it. But what I want to be able to do is take the technician out of the table until the fault is cleared and the technician is free. I have started this process but my head is spinning and I am not 100% where to turn next. I currently have a Busy field in the technician table and I have the code that allows the technician's busy status to change to 0 instead of 1 but I cannot for some reason get it to turn back to 1 when I clear the fault.
I think I may need some sort of If then statement like
If datagridview2.currentrow.cells(4) = 0
Then datagridview2.currentrow.remove
I've been using a FileSystemWatcher to detect changes and this is the code that changes the technicians busy status to 0:
Dim BusyM1 As String
BusyM1 = DataGridView2.CurrentRow.Cells(4).Value
sql = "update Technicians set busy=1 where busy='" & BusyM1 & "'"
Dim commandUpdate As New OdbcCommand(sql)
[Code] .....
And here is a code I tried to use to return the status back to 1 for the technician busy status
Dim NotBusy As String
NotBusy = DataGridView2.CurrentRow.Cells(4).Value
sql = "update Technicians set busy=0 where busy='" & NotBusy & "'"
Dim commandUpdate As New OdbcCommand(sql)
[Code] .....

I have a graphics application I'm working on that displays full screen so there's no control in the upper right to close the application. I have it set up so that a right click closes the application but I noticed that a right click menu comes up on the desk top after my application closes which is no big deal. You could ignore it but I was wondering if there's a way to turn off the right click menu so that it wouldn't come up though I would want it to be enabled after that first click that closes my program.
So the right click would close the program disable the right click menu and then enable it again so that the next right click would show the menu. Haven't come up with anything on searches. I could use something else to close my application but if there's a convenient way of doing this I would like to find out what it is. I have almost every key on the keyboard doing something though I haven't used F1 through F12 at the top of the keyboard. Maybe I'll use F1 if I don't find out how to do this. How to use F1 to F12 to close or do something?
I've been using keypress events to do a lot in my application but for
Select Case e.KeyChar
Case "F1"c
isn't valid.
I tried other things. {F1} etc. I have option strict on. Thus the little c is necessary for characters like "a"c or "b"c.

I'd like to temporarily disable events for a given control. For example, the SelectionChanged event on a combobox might be used to update a display every time the user changes the combobox... but while I'm filling the combobox with values, I don't want the SelectionChanged event to be firing over and over... I need to disable events while the combobox is being populated. How do I do this?

My VB program creates a file on a NAS drive via the SaveFileDialog component in a different user context than the person launching it.It works because the person who runs my ClickOnce deployed program uses RunAs from the program's exe (thereby bypassing the ClickOnce pre processor). The problem is that the program extensively supports drag and drop which doesn't work between the User and RunAs contexts.
The program is a VB 2008 Express Windows Forms Application running on XP workstations with peer-to-peer (workgroup) access control. i need to execute only the SaveFileDialog component with impersonation via the user account we've been using with RunAs. Something along the lines of what RunWithElevatedPrivileges accomplishes in SharePoint Services. This is not happening in a hostile security environment - so, the solution needn't be impregnable.

I'm trying to temporarily change the value of i in a for loop because I've got a problem when entering data into excel.Every second line is has the .marketName "To Be Placed" so they appear blank like this.
DATA 1
DATA 2
DATA 3
I want to change the value of i so there isn't a blank line between each entry.
vb.net
Private Sub BHorse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BHorse.Click
Dim oMarketsReq As New BFExchange.GetAllMarketsReq
Dim oMarketsResp As BFExchange.GetAllMarketsResp
[code]....
It seems to get into an infinite loop as the way it is, even after I change the value of i back.
