Imports System.Net, System.Net.Sockets
Public Class ServerForm
Private serverSocket As Socket

for the first time, when I click on Connect, it is going to connect to server as well and also it works if you click on the disconnect. for the second time if you click on the Connect button, it gets connected but the disconnect button is not working.
I dynamically (by programming text, not drawing in GUI) created a matrix of 10x10 buttons named 'Button1' till 'Button100'. In a formula I calculate a number, say '87'. If I next want to reference 'Button87' and change e.g. the background clolor and text properties, how would I do that? I am creating a PocketPC game using VB2005.

How do I close all opened forms which are created on the fly?

I want to close all opened frmForm1?
I have a form which when button1 is pressed creates and displays a new form. From this form a user has the choice yes or no buttons. Each button has its own handler and script it executes. If yes is clicked i want to run the script and then close both forms. I used me.close() and that only closes the orriginal form and leaves the dynamically created on open. If I place a call to form2.close() in the yes handler sub I get an error that it is not declared. How can i close this second form?
View 4 RepliesIn my program it detects if there is more than one monitor connected. It then creates a form on each monitor screen and you just click on the screen that you want the program to run on.
Here's where I'm having a problem. Everything works great, but when I load my MAIN form how would I call those programmatically created forms? I can't just do frmYou.close.
Here's the code I use to create the forms.
Public myScreen As New Point
Public ScreenReady As Boolean = False
Public sX As Integer'holds screen x width
Public sY As Integer'holds screen y height

View 1 RepliesI have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.
View 2 Repliesi'm new to database programming and am currently learning vb.net and ms sql. I was working on a simple add-edit-delete program and somehow i managed to make the Add button work, with this code:

I am working with MS Visual Basic 2008 Express Edition and MS Access 2007. I have managed to populate a temporary table with data from a text file containing eight fields. I have applied the namespace System.Data.OleDb What I want to do now is: 1) to order the data by a specific field (let's say Fld4); 2) delete duplicate records; 3) append the sorted data to a main table; 4) write the data from the temporary table to a new text file and save to a folder; 5) clear the contents of the temporary table

I'm thinking that as long as I have bin/MySql.Data.dll, I should be fine. I'm obviously wrong.
I am writing a program which includes access to a Microsoft Accsess database. It is running fine on my work computer (windows xp) but when I transfer it to my laptop (windows 7) to work from home it stops running on the "open" statement. I have stripped out all other code so that I just have a program with this in:

Again this will run fine on my desk computer but will not get past the open statement on my laptop.Interestingly, if I start a brand new project on my laptop and paste this code into it - it runs correctly.

View 4 Replies[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?
View 6 RepliesThe Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?

Up came a pop-up menu.

The Query does exist in the Database and I am accessing the correct version.

View 8 RepliesIam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.
Please how can i publish an application created in vb.net along with a database which i created in SQL Management Studio?
