I have a set of textbox's 0-8 each has a label as textbx0 to textbx8. What I need to do is perform something like this:
for z = 0 to 8
result(z) = a + b
textbx(z).text = result
I know this is not complete.I need to write a result to each textbox0-8. I can do this 1 statement at a time, is there an easier way using for, do or while loops?
I have used mshflexgrid for my vb.net program. But it shows error when I try to build because vb.net doesnt support mshflexgrid. Please check my code & tell me what should I do to do same thing there in datagridview? Datagridview doesnt support same code. So would you please tell me what should I write for it?

My code looks very similar to this post Read bytes from NetworkStream (Hangs), which I copied below. ( I realize this is c# - I need a vb solution)
[Code]...
My issue lies in this:
I have a form that takes user input on which tif file(s) to find (which ends up being the getBytes(message) ). When one does this, it always returns one result - the first tif file that fits the criteria, However, I know in certain instances I should recieve more than one match.
Then I send the results to a picturebox and should be able to scroll through results (which this part works fine)I've tried a few ways to get multiple results, but maybe I'm missing the obvious? My best guess is using the asyncronous beginread/write.I've attempted using a for loop but I end up getting a bunch of the same tif files as a result..
I have a for xml raw select query that returns a xml string in server2005 and i would like to write that string to a file using vb.net.
View 2 RepliesI have a gridview with two cells cell(0) is a IP-number and cell(1) is a resultTxt. I have X number of rows. I want a solution that check each row and do a ping to the ip and write result to result. I want to do the ping in a new thread and i want to be able to do more then one at the time. So I want a loop that keeps checking the ones that are not online until they goes online. It's the thread-part I have questions about, looping gridview and doing a ping I can manage, but it I don't do it in a thread the interface freezes.

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. 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:

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.

Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()

encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")

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>")

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 :-)

I 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]
