Is there a way in vb.net to check whether new memory pages have been created inside a process(such as winlogon, svchost etc) For eg : if i there is a certain value that may change if new memory pages are created inside the process. Then i can compare the previous value and the new value (after pages have been created) and make it sure that new pages have been created inside that process.
Is there a way to check whether new memory threads have been created inside a process in vb.net. By hashing the process and checking before and after the threads are created or something like that.
I've created a form with two check boxs and one button. I added this code Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Bg1.txt As String = "C:UsersJoshDocumentsBg1.txt" Dim objReader As New System.IO.StreamReader(Bg1.txt) TextBox1.Text = objReader.ReadToEnd objReader.Close() End Sub End Class

When I am developing an application and I use the 'Data Source' tab to create a database, will that database be automatically created when I use the software on another machine?
I 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 'TODO: This line of code loads data into the 'CallLogDataSet.CallLog' table. You can move, or remove it, as needed. Me.CallLogTableAdapter.Fill(Me.CallLogDataSet.CallLog)
2. User clicks go next to textbox with data entered, then button and a copy of form refered to as browse is created.
3. Form refered to as browse is directed to the url refered to on the form refered to as monitor, in the associated textbox(passed as a parameter to copyForm)
4. A timer is used to refresh the webpage every 10 seconds
What I wanted to happen was the program turn the associated picturebox in form1 green if page is loaded, and black is loading.
This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:
[code]...
I am getting the check value correctly in the database using a Boolean.Here is one of the errors I am getting. Unable to cast object of type
'System.Boolean' to type 'System.Windows.Forms.CheckBox.I am having trouble putting the codes in a code tag or block
My application is like this : i have to search my data from database with some check box and text box when user select check box specific function go on and then when user enters some range of value in textbox then the result will shown in data grid view after that i can print it by selecting data my vb.net code is as follow:

hi there,first of i know nothing at all and my goal is to make a app for xp to check a database and check/patch a iso and then to burn the result to dvd-dl, basically like a app called abgx360 checks the database then like xbox backup creator burns the game, i'd like to make a app to do both, i'm going to college next year in september to learn programing c+ andf a few other things, but thats a longtime away.
I have a Boolean that writes to a data field. The data field(column) is set to YES/NO, if the user check a checkbox, the value is written as check in the data field.The problem is when I search for the user information, I need to get to form to the state it was in when the user submitted it.
Example: If the use select checkbox1 and submits the form. When I search the form, I need to make that particular check box check.
[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?
I'v created a program with a Ms SQL database, registration form and login form. Everything was working well so i detached the database and added it to my program as an existing item before so as to deploy the program. But now i recieve an error when i try to login to the database. The error states that there is a failure connecting to the database and the database cannot be opened
I created a Query in a database in Access. I want to attach it to a DataGridView in VB2010. I then went to VB and connected to a Database. Then I dragged a DataGridView onto the form. Up came a pop-up menu. I Clicked on Choose Datasource, Add a DataSource,clicked on all the next buttons, selected Tables and Views checkboxes and clicked finish.In the next view up pops a menu that lists my Database and it's tables, but not the created Query. The Query does exist in the Database and I am accessing the correct version.

I am writing a small aspx web application that takes in forum information after validation and then opens a database connection and populates the proper columns with data.note: The database is a .sdf file created in web matrix My issue is that even with: Import Namespace="System.Data.OleDb" on the page I am getting: Type 'OledbConnetion' is not defined. I am extremly new to VB, I am coming from java and honestly I do not have all year to read vb code and take classes and read books. I need to finish this app for a client so I am kind of rushed.

I created a small program which one uses the SQLite database. I have a simple table employees, composed of the name and password. I can not write sql script correctly. application code is:
Imports System.Data Imports System.Data.SQLite Public Class Form1
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
I am an experienced programmer but am new to VB. To start, I am trying to create a simple database program. (My ultimate goal is writing a comprehensive database program in 6-8 months)I have created the database and bound the fields to a form.
But what I want to be able to do is add a field to the database and then also bind that new field to a textbox on the form.The new field appears on the list in the Server Explorer window (on my left) but not in the data sources window (on my right.) The data sources windows has a "refresh" option but that does not help.When I manually add a textbox and try going to DataBindings in the property window the new database field is not listed.
I am in the middle of the creation of an application using vb.net. I have a database created in MS.Access which includes 7 tables. I connected this one with my parent program code. Now the problem is that I want to display the data from each column. I have 12 columns and 14 rows in my first table. How can I display data from one column in a Combo box?
I have a connection to an access database, I have used the data sources tool provided because in this particular instance I don't want to do much with it other than display the records (which I can do) and edit them (which I'm haveing some trouble with).I have created a system whereby the database is connected to using the preset tools available like; BindingSource, TableAdapter, BindingNavigator etc.
I also have a button for edit. This doesn't work and I was wondering if anyone could help me with this? I can't really provide any code for this, because I didn't code the connection by hand and the code I have been attempting to use for editting the records in the database doesn't even sort of work.
I have created an application in which I have to make a report with ReportViewver from Microsoft.Everything ok until now. I have created the report and for this report I have created a dataset. This dataset contains data for every month in every year from 2010 to 2015. With this dataset I am populating a graphic but my problem is that I want to select the year and create graphic for one year.I do not know how to insert a parameter in the dataset. In sql is very easy by in Access is different and if I try to put something like ...' where year_column=@year_parameter' I receive an error.
