Saving Data Which Would Need To Be Updated Every Time The User Exits The Program

Aug 21, 2011

I want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.

Cannot Edit Entry After Saving First Time

May 27, 2010

When ever I add a new entry into the database, it will do it. When I click save, it will save it. When I go back to edit the entry after it was saved the first time, and I hit save again, I get a concurrency violation? It only does it when I add an entry. If I close the program out and restart it again I can save all day long as long as I don't add a new entry. First of all, dunno where the violation is coming from, but I only have a message box on my catch statement on the save button.

I have added it to the database using the following code 100 times and it has always worked:
Me.shuttlerunsbindingsource.addnew()

My save code is:
Try Me.Validate()
Me.ShuttleRunsBindingSource.EndEdit()
Me.ShuttleRunsTableAdapter.Update(Me.ShuttleRunsDataSet.ShuttleRuns)
[Code] .....

Why after a million times of using this exact same code is it not working? It will save all day long no problem as long as I don't add a new entry. Here is my add
Try ShuttleRunsBindingSource.AddNew()
EmployeeInitialsTextBox.Text = lblUser.Text
Catch ex As Exception
MessageBox.Show("UNABLE TO ADD! " & ex.Message) End Try

The message box for the add code never shows so I can't see that is causing any trouble. I am using VS2010 and a local database, not SQL. I just tried doing it again, I added an entry, I saved it, I got a successful message. I then tried to change something and I got a concurrency violation when I clicked save again. I then tried to delete an entry and it successfully deleted it, but when I went to edit another entry and save I got the violation.

VS 2008 Saving A Time Value In SQL 2005

Mar 22, 2009

In an VB2008 application an email can be saved in a SQL 2005 database. The date, time and subject are saved in SQL. Let's say the receiving time of an email is 12:56:55. After saving the values in SQL a SELECT of the SQL table gives me a time of 13:56:55. From this result I conclude SQL is saving a time value differently. - Is this difference come from the time zone? - Is this difference come from the daylight saving? - Is this difference come from both? How can I easily compare these two values?

Sep 19, 2010

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

Usercontrol With Designer Browsable Property Not Saving Value At Run Time?

Aug 17, 2011

I have been making a control and have added a property for a list(of CustomClass). The custom class contains a string, an image and a list of another custom class which contains a string and an image. I have added this property to the designer by adding the browsable attributes and all appears to work correctly with this.

My problem comes when running the program. I can set all of the values within the property and I can go back to them and they are saved, however, as soon as I run the program, the values are wiped out as the property is set to Nothing.In order to allow my property to be edited and saved, I realize that I must initialize the list and have done so in the accessor method of the property (if the property's value is nothing).

I have modified the values in the designer and placed a breakpoint on all of the items which use the property and it's underlying field, as well as on the property's methods itself. The first breakpoint hit is of it being accessed and the value is always nothing.

I'm not sure where the values are supposed to be stored as I have checked the designer code where it would normally store types such as strings and I have checked the resources to see if they have been saved there (like an image would be). After running the code, the values in the designer are wiped out also.

Date / Time Stamped And Numbered Filenames When Saving To JPEG?

Oct 19, 2009

Right now the existing VB code I have uses GUID to generate "random" filenames on save.
For instance:
ff8514d389a041649fd8b925a32f2b51.jpg
e1c938560fc1464ab2138065fc4661d3.jpg

Instead I want a date stamp, Time Stamp, and numbered filename:
For instance:
20091015_131644_001.jpg <--(Date_Time_NumberIncrement)
20091015_131551_002.jpg

Or something along those lines. The current code (which saves a jpeg to a random GUID filename) is below:
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.IO

Saving Information So Program Remembers Next Time User Signs In

Feb 25, 2010

i want the user to login, and the first thing is, having the text document for that(if theres a safer way to do it, let me know) then it goes to the weekly sales page, but theres also the goals for the sales, which rarely change, but if they do i would like them to be able to change them, then next page is the list of the workers, and if they need to i would like them to be able to add workers. so my question is: is there anyway that maybe i could save both the goals, and the workers in the text document, and when they need to change it/add workers it will save it in the text document and the next time they sign in the changes will be permanent? also is there a way to delete the user once they have been created, other than going into the txt document and deleting it.

Time Error When Automatically Adjust Clock For Daylight Saving Changes Is De-selected

Jan 15, 2010

I have noticed in a windows-based VB application I am working on when the "Automatically adjust clock for daylight saving changes" is de-selected, the time in the application is off by one hour. Is there anyway to make the application not sensitive to that and just display the date value that is retrieved from the database?

Saving Replicated Data - Current Data Saved To Appear In Page Within All The Relevant Fields?

Jun 2, 2010

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.

60K Data Saving To Database

Nov 6, 2011

I'm working on a project which are generating some data from my VB.NET software and I wish to save those data into sql server. But my concerns is the speed of saving and the large amount of data. For every 0.5s, one set of data will be generated and the process will keep running for about 8 hours, so at the end of 8 hours, roughly there will be 60,000 set of data generated.May i know what is the best option/method of saving the data into the sql server in not hanging up my software and also keeping the pace with the speed of 0.5s data being generated?

- Speed of 0.5s. I have to maintained for every 0.5s, one data must be generated. Cannot delay too much.

- I can afford delay in the sql database, meant the data might not be necessary close to real time.

Data In Application Not Saving

Aug 19, 2011

I have a small application that consist of five tables. The main table is called inventory. I have four tables linked to the Inventory table

[code...]

I can go in and enter data, create a new record and add more data and then click Save - nothing happens. I can cycle through the records and they will show. However when I exit and reenter the program (stop/start debugging) done of my new data is displayed.

I am thinking the problem has to be with the four tables connected to the main table via the ID's. Although a record is not being added to these subtables. So, I am not sure what's going on.

I have provided the code below. Please take a look and give me some direction.

Dim newFileRow As DataRow = Database1DataSet.Tables("tbl_Files").NewRow()
newFileRow("File Name") = fleName
newFileRow("File Path") = flePath

This seems to work ok - the new Data immediately appears in the ListBox. However, as soon as I close the form all of the Data in the DataSet is lost.

Form Data And Saving

Oct 11, 2009

I have created a form, that calculates Hotels billing, with one box I can input Number of nights a customer stayed which is £32.50 a night per room and the other box £4.50 for breakfast, there is a deposit of £25.00 which gets deducted upon departure. I have created this form with success along with a clear button But here is the tricky part- I want to create a total button which will display a summary information about the bills paid on that day regardless of how long they have stayed and how many breakfasts consumed. this should include, the total number of bills paid, the total number of nights paid for, the number of breakfasts paid for, the total amount of all the bills added together including the deposit.
