How do you display your result of a calculation in a message box?
Code
MsgBox("Average = " & textbox1 & "" + vbInformation + vbOKOnly)
Is there a way to show the value retrieved by an SQL statement in a message box? In context, my SQL statement searches my database to find a customer record that matches the details entered into the text boxes on the form, and retrieves the CustomerID. Is there a way to show this CustomerID in a message box?
The SQL code is:
SELECT customerid
from customer
where cust_forename = @custforename and cust_surname = @custsurname and cust_house = @custhouse etc
I'm a complete Visual Basic (2010) beginner and I've got a Memory game to complete for a school assignment.
When I have two cards match in my program, a message box will pop out and say "match". If the message box does appear, how can I then get a "1" to then be added to a text box within the program? I would like to have the points accumulate for each "match" message box that appears.
I've created a custom MessageBox (a Form), that has buttons Yes and No. There is a function popUp() to show the MessageBox. I would call the MsgBox in a parent as follows:
CustomMessageBox.popUp()
Now I want the message box to return a value:
Dim a as Intger = CustomMessageBox.popUp()
But this should only return once the user clicks a button in the message box.
My popup sub:
Dim thread As New Threading.Thread(AddressOf GetResult)
Public Function PopUp(Optional ByVal ErrorMessage As String = "", Optional ByVal Title As String = "", Optional ByVal ButtonType As ButtonType = ButtonType.OK, Optional ByVal MessageType As MessageType = MessageType.None)
[Code] .....
gotResult is a Boolean = false. It the user clicks a button gotResult is changed to true.
result is a integer containing the number of the button clicked.
When I run this code, the result is returned, even if the user doesn't click a button. I understand why, because the main thread of the form is not "paused" while the user has not clicked a button. How can I pause the message box itself, until a button was clicked?
I've tried this:
Public Function PopUp(Optional ByVal ErrorMessage As String = "", Optional ByVal Title As String = "", Optional ByVal ButtonType As ButtonType = ButtonType.OK, Optional ByVal MessageType As MessageType = MessageType.None)
[Code] .....
But now the whole message box is captured in a loop and the message box is like disabled, because it waits for the loop to end, so the user can't click anything.
How do i code so my program will give me a message box if there are no result of my database search?
there is the code for the search. [Code]
I am developing a custom messagebox class like the following-[code]...

View 1 RepliesI 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. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

View 2 RepliesI am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:
[Code]...
Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?
I have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")
encryptAES.Mode = CipherMode.CBC

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

how to create an error message by message box to tell the user to enter a number only if they key in a character value?
I MEAN AFTER THEY PRESS THE CALCULATE BUTTON
Private Sub btnCalcFat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalcFat.Click
Dim intFat As Integer
intFat = Integer.Parse(txtFat.Text)
lblResultDisplay.Text = txtFat.Text * 9
End Sub
My text box is call txtFat
just curious if there was a way to make the text in a message box scroll across the message box
View 1 RepliesI am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

I need to run TWO Threads in a web application, .NET. 3.5 Both methods MakeRedCars and MakeBlueCars need to run at the same time as both take 5 seconds. I have tried many example codes with very bad results. I dont need anymore than 2 threads. The main issue I am having is knowing how to wait till they are finished and also how to store the results from each.Each of the Methods do different things, one is a web request, one is a sql call.
Both methods return a list of(cars) for example do:
carList.addrange(MakeRedCars())
carList.addrange(MakeBlueCars())
for each car in carlist<br>
response.write(car.colour + "<r>")

I have implemented the answered below and with empty objects all works well, as soon as you hook in a database call that returns the data/objects studio does a JIT and crashes.
I need to check if my SQL statement returned any results from the Access db I'm using to store my data.

As of right now I am getting no compile errors with my code, everything runs they way it is supposed to go except for one minor detail. I have a private function named MonthlyPayment() that does a calculation for a loan. The calculation runs as expected and I get the correct results by typing in Console.WriteLine(MonthlyPayment()) but it is not in currency format. To fix this I set FinPayment equal to MonthlyPayment [FinPayment = MonthlyPayment()] and typed in Console.WriteLine(FinPayment.ToString("C")), But this just gives me NaN as a result.
Here is my full code:
' The following code was created for McBride Financial Services to use to amoritize loans.
' This console code will calculate and display the monthly payment amount to fully amortize a loan.
' This console will prompt the user to input values for the loan amount, the term length, and the rate.

View 1 RepliesI've got two list boxes on a standard form - one listing cities, the other capitals.
If the user selects the correct combo, and presses a check button, a standard msg box is displayed with congrats etc.
If the user selects the wrong combo, another msg box is displayed with a Yes No selection, to the question of if they want to have the correct answer selected for them.
Now, I've got everything working apart from this last part - having the correct answer selected. Here's the snippet of one of the If parts.
Just a word of warning - yes, it'll obviously be 'messy' and probably 'wrong' to anyone who is even half decent at VB.NET, but I've only just started, and it works for me, so that's all for now :-)
ElseIf lstCountry.SelectedIndex() = 4 Then
If lstCapital.SelectedIndex() = 0 Then
MessageBox.Show("You got it right!", "Correct!", MessageBoxButtons.OK)
Else

Just want to stress again - I haven't given up at the first hurdle - I've been trying to figure this out for well over an hour (probably more) now. Whatever combination I try seems to be wrong - when I press Yes it just stays on the currently selected item.
