End Result Of Combobox Selection Keep Showing Same Multiple End Result When There Is Only One Entry?
Dec 10, 2010I 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 RepliesMake An Array And Put Result Every Time The Serial Port Gives A New Result?
Oct 14, 2009I 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)
Limit Result Being Put Into DataSet And Get Next Result From Database
Apr 16, 2010I 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?
.net Encryption Result Does Not Match The Xcode Encryption Result Given The Same Input Parameters?
Jun 21, 2011I 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")

.net - ASP.NET Two Threads, One Result?
Sep 14, 2011I 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>")
next
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.
Checking For A SQL Result?
Dec 2, 2009I need to check if my SQL statement returned any results from the Access db I'm using to store my data.
I have this code atm:
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:Computing Projectdatabase.mdb;")
cn.Open()
[Code]....
I would like to be able to check (maybe via a boolean value or something) that this result returned a query. I'm using VB.net.
Code Gives Out NaN As Result
Feb 29, 2012As 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 RepliesForms :: Get The Result Of A Yes/No?
Sep 30, 2009I'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
[Code]....
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.

User Gets Different Result Than Do
Mar 30, 2009I have a wired problem with the windows application that I wrote for a client. I used the vb.net for this application and the database is SQL server express. I created the setup for this windows application and the setup contains .net frame work and Crystal Report's component too..The problem is sometimes the application user gets different (and wrong) result on their work station than I do on my work station.For example we run the same report for the same Case the information that I see on my report is not the same as they do. Incredibly their reports are wrong and mine is accurate. I even tried running the setup on my co-worker's PC and he is getting the same result that I do..I used connection string to connect to the database (via Config file).The other problem is I set one report to be shown in specific Paper Size, Again it is working fine in all the computers that we have in our company but they users seeing this report in A4 paper size..[code]
