Deleting Records From A LstBox And Dat File And Setting Reminders To Date In Dat File

Aug 2, 2010

I am creating a program that allows a person to enter details about their farm, stock, and machinery in order to electronically keep track of all of the information. I have created the forms and done all the coding for the data entry, and now what I would like to do is allow the user to delete a single record from the .dat file. I am able to delete it from the LstBox (using a "Delete Entry" btn coded simply with

lstvehicles.Items.RemoveAt(lstvehicles.SelectedIndex)

(using the vehicles section for examples)), but I am unsure of how to delete it from the .dat file as well, to prevent it reloading upon data change / program reload. Also I would like to be able to have a reminder come up on the program start up that gives a reminder to (in the vehicles instance)when a vehicles rego is due, the date being associated to a date that is entered into the same lstbox data using a datetimepicker.

DateTimePicker Only Adding Reminders To Tomorrows Date?

May 16, 2012

I have a program created that allows users to enter reminders in a text box, where they choose a date on a DateTimePicker, and hit an "Add" button. This then adds the date and time the reminder was created to a table in SQL Server 2005.However, when they click the "Add" button for a reminder to be added on today's date, its only adding it to tomorrow.

File I/O And Registry :: Deleting Lines In A Sequential Text File?

Mar 22, 2009

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...

That is my record file

Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

Deleting Records Using Combobox?

Apr 25, 2011

I can't figure out whats the best code for deleting a record from the database using combobox in VB.Net. the navigation of my combobox works fine.. when i click the dropdownlist of my combobox and select another name, the selected row on my grid also displays records the same as what is seen in my navigation boxes.... but the problem is when i am going to delete the records.

Here's a photo of my sample program :

The selected row on my grid is the records that i am going to delete.

Here is the code for my delete button:

Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.TblCreditBindingSource.RemoveCurrent()

File I/O And Registry :: FileStream File Creation With Date?

Apr 16, 2009

I have found many pages referring to having the date be part of a txt file being created, but not like the way I need. Having said that, this is what I've got.. [code] I read a page on working with txt files and learned what I could from it. It said to use the method in the beginning of my code for creating the file. It works great, but I would like to have a new file name everday, hence the date being integrated. So even if program was running, when midnight hits, a new txt file is created and new entries are written to that file. But I can't even get the date to be put in there. Everytime I try to make this work by using methods I read about in other pages, I get a syntax error, or a warning saying an end of statement is expected. I'm not sure those methods are compatible with what I've already got going.I was actually trying to store these values in a database, and I got real close I think, but I couldn't get any help to fix my problem so I'm trying to write to daily txt files instead. url....

Deleting A Created File

I have an aspx page in VB that fills a pdf with data from a web form.I'm using iTextSharp for this and I have no problem with this.This is the second time I've created anything for pdf's and I'm using the code from the first script.The first script wrote the filled in pdf to a directory on the server where one person could access those via another aspx page. I wrote that code probably a year ago.Now, instead of having the filled in pdf sit on the sever, I have to email it, which I was successful at doing.The only issue left is to delete the filled in pdf from the directory.I tried to use file.delete(), but I got an error stating the the file was being used by another process.how to stop the process in order to be able to delete the file.[code]
