Get Results From A Query Into Multiple Textboxes?

Oct 17, 2009

I'm not sure how to do the following (in VB.NET), I'm hoping you will give me some insight or examples on how it can be done. My database is an SQL one.I have an assets table, which in it has the amount, growth percentage, income percentage. There are multiple assets per client.

I need to get the amount, growth and income into three separate boxes or variables and I'm not quite sure how to do this. The only other problem is that there would be two or three rows returned also, which need to have those three variables or textboxes again.
So for x amount of rows, I need 3 variables which the amount, growth and income will go into.

The reason I need everything into variables is that I can't find an effective way of showing each assets growth over x amount of years and the income it will produce into a data grid view. I'm able to do it if I specify what the growth and income are on the form, but not through the query.

[2008] Query Database Using SQL And Displaying Results In Datagridview?

Sep 25, 2009

I had done this by using the query builder (in VS Studio) but soon found out thay I gain no points by doing it this way as I am not using any code. I have tried to adapt the code I had to insert data into my database, just changing the SQL sintaxa and some other bits, but it is not working yet. Well, it gives results, but I think it is still geting the results from the query I had built using the query builder. Here is the code I've got so far:

Public Class Form2
Private Sub btn_search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_search.Click
Dim str_search As String = txt_search.Text
Dim str_dob As String = txt_dob.Text

Displaying Search Results In A New Form?

Jun 6, 2011

i'm working with a sql (2005) database and using visual studio 2010. I've created a system where one of the forms is a find/search form. A user can enter in for example, a customerID and once they click on "find/search" the customerID will be searched in the database and if found, all relevant information about the customer will be retrieved and displayed in another form (find/search results page). I realise that this can be done using an SQL statement like follows

searchStr = "SELECT * FROM Customer WHERE CustomerID LIKE CIDTextBox.Text%"

What i'm unsure about is how to execute this SQL statement once the "find/search" button has been clicked and how to display the founded results in another form.

Searching A File And Displaying Results?

Nov 29, 2010

I have to write a program that allows a user to input DVD info such as DVD Name, Year produced, Running Time, and Rating. The user then clicks a menu item "New" to save that info to a file. Then the next time the user inputs new DVD info it has to append the new data to the same file. (I got this far and everything is working writing and appending data)Next the year has to be able to search by DVD Video name and it has to print the info in the text boxes on the form, if not found then a messagebox should say not found. When I use the sub procedure that I have created to search the record it always comes back as record not found although the record in in the file.

Option Strict On
Imports System.IO

Loading Results Into An Array To Be Used For Displaying Just Partial

Jul 14, 2009

The assignment called for a VB.Net (not web based) program that would accept user input for the loan amount, interest rate, and term of loan, and display the monthly payment of the loan then list the loan balance and interest paid over the term of the loan. the list will be longer than the screen so use loops to display a partial list, hesitate, and then display more of the list. So, I did exactly that and the program works fine. However, after submitting this program for grading, The instructor for the class tells me, "One thing you should work on is not using a timer to pause.

You should not use a scroll bar either." He says I should work on loading the results into an array or use a loop with a counter that can be used to display a given number of results with a more results button for displaying more (but without a scroll bar?). Like I said, this program works fine and I am not asking anyone for any specific code (some sort of example would be great but not necessary) What I am asking for is an explanation of how I would go about loading results into an array to be used for displaying just partial results at a time in some way other than I used here: [Code]

Looping Through Textboxes In Groupbox Give Odd Results?

Jul 7, 2011

I have the following code:

For Each control2 As Control In GroupBox3.Controls
If TypeOf control2 Is TextBox Then
Dim txt2 As TextBox = TryCast(control2, TextBox)
If counter > totalBoxes Then

[Code]...

What I am doing is looping through each textbox in groupbox3. Then checking if the counter(total number of grades that are inputted in the form) are greater than the totalBoxes(which is set to 0) and finally I am putting the actual grade(A,B,C,D) into the textbox. The problem is that it is starting the loop at textbox 8(I have 10 textboxes) for some reason and going from there. Does anyone know what the problem is with my code?

I'm not quite sure where to begin with this. This is basically how I'm trying to get it to work. I will enter the ID of a Hire Record in a textbox, hit the show hire record at which point it will materialise that hire records details in their associated textbox fields.I attached a screenshot of the form in question. I can also create a new record as you may be able to see by typing in the details and hitting create record (this is not a problem, i already understand how to do this), but I also want to be able to display an existing records details in the textboxes again

How To Prevent .net Combobox From Displaying Multiple Results From A Single Data

Dec 9, 2010

I am currently having a headache on how to solve this problem that i am facing.here is the situation:I have a combobox and a list box on the main form. The combobox will get the data from the ms access database.In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987

So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown.

VS 2008 - Displaying / Printing Program Numerical Analysis Results?

Oct 23, 2009

I am writing a VB.NET Windows Application which takes numeric user-input and performs a complicated calculation, yielding many numeric output variables. Previously, I wrote a similar program in VB6, which output the results to a rich text box using fixed-width font in order to organize data in columns and used asterisks to delineate table areas and section borders. I then used the printer object for printing the output. This method was very archaic and difficult to modify when changes were necessary.

Multithreading - Single WinForm Displaying Two TextBoxes

Jun 15, 2010

Here's the setup: I've created a class that represents a temperature and humidity monitor. This class handles all of its own operations (connects to the monitors via TCP, reads the temperature and humidity values at set intervals, logs the data, sends email notifications, etc.). I've got a single Windows form that has two textboxes for displaying the values of temp and humidity. When I start the application, I simply instantiate an object of this class and let it do its thing. Every five minutes, it opens up a socket connection, pulls in the data I want, sets the Temp and Humidity properties of the object to the values it obtained, and fires a DataUpdate event which is captured in an event handler in the Windows form.

When this event occurs, the textboxes on the form are updated with the values from the Temp and Humidity properties of the object. Works like a champ. However, I've been playing around with multithreading. Since a disconnected device will cause my entire application to block when it tries to connect, I decided to place the socket connection/data acquisition method into a separate thread. If it can't find the device, no big deal -- at least it doesn't lock up my UI. This thread is instantiated and started inside the object code, NOT the Windows form.

Here's my question, the socket connection/data acquisition method is run inside this new thread and sets the properties of the object when it's done. So, why do I get an illegal cross-thread exception on my Windows form, now, when I try to update the textboxes? It seems to me that the instance of the monitor class is running in the same thread as the Windows form. I only employ a separate thread when I want to run the socket connection/data acquisition method. Is my understanding flawed? I can display the updated property values in message boxes that are called from the Windows form. I just can't manipulate the textboxes.
