Logging The Time A New Record Was Created And Added To The Database And Then Adding Interest To The Balance?

Feb 18, 2009

Hi how's it going. In the middle of coding a banking application for a project. Part of it involves mortgage interest repayments. Was wondering if there was any way of logging the time a new record was created and added to the database and then adding interest to the balance owed periodically every 30 days..

Adding To Collection Just Continually Duplicates Added Record?

May 7, 2010

I have run into this problem a number of times, and I am not sure what I might be doing wrong - or if this is just a bug, or not going to work.I have a collection that I setup on my own (eg, collection class). I then cycle a Log file that has text entires and I read those, and then parse the entry and attempt to add it to my collection.

But as each entry is added, ALL records just get duplicated - in other words, as I add entry 2, both entrys 1 AND 2 wind up with the same values - as I add 3, all 3 entries get the same value - and this continues no matter how many entries. For example,
if I added 100 entries, I would have 100 duplicates of the last record added.I have stepped through the debugger and watched this occur and just cannot figure out why this is not working as it should. Here is the code...

While
Not objReader.EndOfStream
' Read one full line

[code]....

No matter what I do, my lstSent collection just winds up with EVERY entry being the same as the last entry added.

End
IfFalse'
Add the elements into the collection if its a "Sent" itemElem = objReader.ReadLine

Adding A New Record In .NET To Access Database?

I'm at another wall in my project. I've been trying to get it to add a new record to a table but I got a message that said "Object reference not set to an instance of an object" but I have no clue where the error is popping up. I am also unsure of whether the coding for adding a record will actually work on not.Here is the code for the form with the bits subs that I'm sure aren't the problem removed (as they have no relevance to adding a record);

We're trying to work out some code for saving from a textbox to a database field without using DataGridViiew. We have it working using the automated controls that Visual Studio gives us, but if we have a form with text boxes, can we make it so that, on a button click, it dumps that stuff into a field in a table?

DB/Reporting :: Insert Record Not Adding SQL Database

Dec 10, 2005

I have been following a tutorial in a book Vb 2005 Jumpstart Ch 4..Anyway I have followed the books code exactly and the program runs.It connects to Amazons web service and allows the user to search and display books, the application also allows the user to save the titles that they wish by clicking an Add Title button, when the user does this the current focus title is saved to the database and can be viewed off line.When I hit the add title the record gets saved as I can hit the catalog button which opens a new form with a datagrid that has all the titles I just saved in it!! But when I close the app and run it again the catalog is gone?? back to no records again?Now ive never worked with SQL databases before and this is me just having a go at .Net so I have no idea whats wrong or where to look.[code]

Increment A Primary Key That Is An IntDigit When Adding A New Record To A Database?

Mar 16, 2012

How do I increment a primary key that is in integer digit format to a record when adding or pressing an "Add New" button that I have on my form. In other words, I have a 'Add New' Button that has the code following:

[code]...

As you can see from the above code, that most of the textboxes are cleared so that a enduser can insert his or her values and information. Currently, I do have the OrderNumber which is the primary key cleared, however, I would rather have this field auto incremented to the next digit. For some reason, at the moment, I just do not know where to begin to set this field so that a digit canbe inserted and incremented rather than cleared.

Foreign Key Constraint Error / Parent Record Does Exist But Won't Let Child Record Be Created

Feb 21, 2010

While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.

I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.

I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

List To Update Every Time And Show The Values Each Time To Which The Previous Value Is Added To The New Calculation?

Jun 22, 2010

The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:

Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....

I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:

Public Class frmFutureValue
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click
