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:

My save code is:
Try Me.Validate()
[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.


Saving A Modified TextBox Entry

Apr 29, 2010

Okay, that snippet made the file I was trying to open in the %USERNAME%AppDataLocal folder worked perfectly, again, many thanks - But now I'm 3/4 of the way through my program, and I've hit a wall - I have the exact same program I made in VB6, and it works to perfection, but I am TRYING to switch over to .NET, and am finding a lot of difficulties in getting certain things to work - My biggest headache right now [ Which is basically the finishing of my program ] is a bit hard to explain, so this may be a rather long post: One of my programs that I use to keep track of my Music hard drive outputs to an XML file, in which there is one line I would like to be able to 'Replace' through the program I am making now to a different user-defined string, and close [ Applying string change/save ] the XML file. I have my Main Form, a TextBox1 [ I can't get the XML to open in a ListBox like I wanted ], TextBox2, a 'Locate String' Button, a 'Modify' Button, and an Exit Button. I open the XML file with this in my Form1_Load event into my TextBox1:[code]

The <DateValue> is the line I want to be able to modify [ Which the entire string looks like this: <DateValue>2010-04-10T10:00:03.5009756-04:00 </DateValue>, and I want to be able to change the date and time to whatever the user specifies ], which once the XML is loaded into TextBox1, when the 'Modify' Button is clicked, that string is then loaded into TextBox2... This is where I am lost - How can I apply the modified string to the TextBox1.Text [ Entire XML file ], and save it upon program end, without the rest of the XML lines being disturbed? I realized I needed another Button - The 'Modify' Button now loads the selected string into TextBox2, and I have a 3rd Button to 'Apply Modification', which I want to update the <DateValue> string in the TextBox1 [ Full XML file ] from the modified string in TextBox2, then save on exit - Hope this helped clarify things.So here's the routine:

1. Form loads, opening the XML file, and loading it into TextBox1.
2. User clicks 'Modify' Button to load searched string into TextBox2.
3. User modifies TextBox2 entry.
4. User clicks 'Apply Modification' Button, which changes the searched string in TextBox1 to the modified user-defined string.
5. User clicks 'Exit', which saves the XML changes from TextBox1 [ Without messing up the XML file format ], and the program ends.

DateTimePicker Requires Entry The First Time?

Jun 23, 2010

I have a datetimepicker on a form. It is not bound to a table field. When I open the form, I click on the arrow on the right of this control, the calender picker appears, I click on a date, and then I have to hit enter for the picker to close and the date to transfer to the control.After that, I can click on the arrow, click on another date, and the picker closes immediately and the date value goes into the control. Why do I have to hit enter the first time? I would like to be able to transfer the selected date to the screen the first time with just 1 click and without hitting enter.

Edit The Splash Setting Time From 1 Second To X# Seconds?

Feb 3, 2011

Basically, my app has †the†main†form and a windows form "splash". Let me explain, this "Splash" is a WINDOWS FORM, not a splash form; its just named splash because I want to use it for that reason.In my project settings, my main form is my startup, and the splash form is my splash. This splash form has been coded on a timer for 10 seconds, but when I set the splash form as the splash setting, the form shows up for 1 second and goes to the main form.What I need is to edit the splash setting time from 1 second to x# seconds (preferebly 10)

Forms :: Auto-Detect BarCode Scan Entry OR Manual Entry - Cash Register?

Sep 8, 2009

i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....

Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.

Communications :: Differentiating Bar Code Entry To Keyboard Entry?

Jul 10, 2009

I am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:

1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?

2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).

DB Synchronisation Behavior - Can A User Read The Entry While Other User Is Updating That On Exact Same Time

Jul 25, 2011

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".

Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?

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?

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.

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

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.

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.

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?

Sep 6, 2009

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).

I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
