Make Update On Class And Then Put It As DLL File In The File Of Program?
Nov 20, 2011
I create a project using query sql ( Select, Update,Delete,Insert ) in many various way. example by Select with condition ..etc someone work in programing field. tell me that you are not profession in using vb.net , because you have to use OOP instead all of these Sql query. because if you want to make any update on your program after start to work on the Pc you will open your project on design and change the code. but in OOP you will make update on class and then put it as DLL file in the file of program.
im slightly new to VB, i was wondering how I make the program check a file for an update, i kknow there is an option in the app settings, but when I go on it it doesnt recognize .vb or .exe files to check from.
If i uploaded updates to a server, how would It check that for updates? and what file type would i need to upload it as?
I am making trying to make a program that can read the file information directly from a specified file, but I am having a lot of difficulty reading things like file comments.An example of this can be found in windows XP when you alternate / right click on any file and click on properties. You'll get a lot of extra information.Now I have a few questions about this.
1.Can this information even be read in VB.NET 2.If so how 3.If not do I need to create some kind of data file to store the file information
I have a Windows Form1 with label and i want to update the Form label text from the class file. I can able to get the Form1 controls from the class file but it is not updating the value in the Form. VB.net
Below is the Form1: Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I have a function list of 75000 for my project. I want to load each class file dynamically and need to add one line on top of the function and to lines in the ending. Which is the best way to update a specific part of the file. I don't want to make a small mistake here since its my source code and globally using.
Form1.vb Imports System.ComponentModel<br/><br/>Public Class Form1 Public Delegate Sub updatePB(ByVal value As Integer) Private bgworker As BackgroundWorker = New BackgroundWorker
1. Private Sub BooksBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BooksBindingNavigatorSaveItem.Click
Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
Private Sub BooksBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BooksBindingNavigatorSaveItem.Click
Tried searching and found some related issues but none exactly like I was having I iterate thorugh a DGV and write to one of the fields of the row. After it writes this field, I do an update() command.
I am trying to write a simple application that monitors the COM port and writes the incoming binary data to a file. So, I gathered a File class is provided, but looking at its methods list in the Help page, I see no method for writing individual bytes (and the Write methods seem to close the file after writing).
How can I write a byte array into a file, keep it open and repeat this as necessary?
Sometimes in my web applications I used to get this sort of error, I have no clue why is it coming however if I refresh the page few times the page is loading normally.I am using .net framework 2.0 and visual web developer 2005.
I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...
How can I make the class recognize that the interface exists but is in a different file?[code]...
i would like to have a shared function in a separate class file to address the form location . but i dont know how can i get this to work. if i use this below code in my form its working . but i cannot move this to a class file.
Shared Sub Formlocation() Me.StartPosition = FormStartPosition.Manual Me.Location = Screen.GetWorkingArea(Me).Location End Sub
I'm trying to create a program, that upon opening, will read an input file containing a delimited employee record. The record will contain the name of the employee, their salary and the number of years they have been employed.I'm looking to display only the name of the employees in sorted order(alphabetically) and then when the user of the program selects a particular employee, I want to display the salary and number of years for that employee.I would like the user to be able to edit the recors for the employee and I would also like to have a way for the user to be able to add/remove an employee record and update the input file before the program is closed.
I've just completed my first project (horay for me), and have compiled it, although i'm not sure if i've done it correctly. What its done is made a directory with 'setup' and 'sliding scale' (sliding scale is the file name) with another directory of 'application files'. Now none of it uses any form of databases, all it does is allows the user to input 5 sets of figures and then calculates a price. How if possible can I get it to be just sliding scale.exe so that way others can use it without having to download this .net framework stuff (if thats made any sense)?
i'm trying to make a program that searches for a specific file in a specific file, so when the program loads it "writes" in checked list box the names of the drives installed to the computer, but what i want to do is: when the user checks the box, i want it to search for the file in that drive, but i don't know how to do it...
I'm using:
Imports System.IO Imports System.Collections.ObjectModel Public Class Form1
[Code].....
how to make it search in the other drives using the checked listbox?
What I want is to make a custom file with my program. This file we will pretend is called InfiniteMapFile.INMP and the file has no contents therefore we need to add contents. There are 3 pixture boxes and 3 text files. The data for each of these files needs to go into InfiniteMapFile.INMP with the associated names, then later on be taken out if needed. Here is a diagram:
you can see what I mean by putting the files within it, I would have made my file look more like a box, but we're not 5 years old and I'm sure all of you will understand.Just knowing how to combine multiple files in general will help.
How do I make a program a default program for a file? As in if I had just a basic .txt file editor, I could make the program the default program for the extension .txt. I have tried just doing it in Default Programs, in Windows 7, and Windows XP. But when you click on the file it opens the program, but does not load the file. I plan on actually releasing the beta 2 a Office Suite I created.
I'm trying to make a file explorer for my program. Let's say I use an install disk to get this on my computer. How would that program set up the explorer so you can view and search My Computer, C:, and/or disk drive?
