View 18 RepliesIm writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb
database_connection()
sql = "SELECT * FROM tlalist"
[Code].....
In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.
I have an app that I am developing to keep track of my members' names and phone #'s. I have all current names and numbers in a csv file and they are read into a structured array. The app can add, delete, and modify members. I have everything coded except the 'Modify' menu item. The list box is populated with only names at run time, I would like to have both the name and phone number displayed in the two text boxes I have on the form when a name is selected from the list box. I can get the name to display in the text box I have for names, but since the phone number is not in the list box I am wondering how I can get it into the appropriate phone text box. I used txtName.Text = lstMemberList.SelectedItem to get the name displayed but since the phone number is not in the lstMemberList list box I cannot figure out how to get it into the txtPhone text box.
View 4 RepliesI am having a hard time displaying the contents of a text file that i read into an array. I read the text of the text file into an array but then i need to display it but i can't seem to get it. I also need to create a criteria to match whatever letter is entered into the textbox and display the contents of the file only beginning with that letter. I know i have to use a substring to read only the first letter but I can't even display the contents of the file from out of the array. Here is what i have so far.

I started programming in VB many moons ago, but I put it down about a year ago. I picked back up a project I was working on a few years ago and Visual Studio 2008 Pro had to convert it. It seemed to work just fine but I wanted to make it "look .NETish", so I simply copied all the controls and code into a new project.The new project won't display information stored in static arrays on a Rich Text Box. The arrays are declared public in a code.vb file and the array is populated in the load event for the main form.I've tried inserting a "test" button to see if I could somehow get it to display trying a few different things. Essentially:
Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click
Dim test As String = Gems(0)
[code].....
Has array conventions changed or something in the past year or so? How do I extract the information contained in Gems() that I have so maticulously entered so long ago
I need to construct a small program that "stores" entered test scores into the program then when a button is clicked, it will display the scores with the appropriate names in the box below. The values are the names "Brian" "james" "jimmy" "jock" and "gok" and there are two test scores "main test" "small test".. I need to be able to "store" these in a "database" and then when the user clicks "show marks" it displays all the names with the marks in a table format. I'm totally screwed and i dont know where to start..I already have done a little coding for the gui such as a password entering system and all that works, all I need now is this storing thing.

I need to convert hex values aa 01 00 17 f4 2f (as contained in byte array FrameData) to display in a label control as AA:01:00:17:F4:2F
HexDump(FrameData(2)) converts the aa (which has been converted to Decimal 170) into 31 37 30 !
similarly I need to convert hex data ('02 00' contained in byte array FrameData) as
0x0200."0x" & FrameData(1) + FrameData(2) displays the data as 0x20. How would I convert the '02 00' hex data to display as 0x0200?
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]

View 6 RepliesI have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.
i want to see if i can get my hands on a working example of a 2d array something along the lines of continents and 5 sample countries from each continent.i would also like to know how to loop through a 2d array - i know i need a loop inside a loop but cant find any examples.i know to declare a 2d array its like: dim arrayName(,) = {{"sample","sample"}{"sample2","sample2"}}

I'm writing a loop to go through the first array of a 2D loop, and I currently have it like this:
For Each Dir_path In MasterIndex(, 0)
'do some stuff here
Next
But it's giving me an error, saying it expects an expression in the first field. But that's what I'm trying to do, loop through the first field. How do I fix this? What would I put in there?
EDIT: to clarify, I'm specifically looking for the 0th element in the subarray of each array, that's why that second field is constantly 0.
I define a arrary.
Dim myStr(100) as string.
Then the length of this array is still 0. Then is risky to cross the bound. So how to intialize this array without using a loop?
I've been looking far and wide to find the answer to my question. Its probably has a simple answer, but I am new to VB2008 and can't figure it out. I have a web form setup 30 textboxes, and am trying to find a way to quickly add them to an array through a loop.Their ID's are all - TextBox1,TextBox2 ect. I have this loop here that runs with no errors, but nothing shows up in the TextBox's on the web form.If the TextBoxes are already on the form, do I still need to declare new boxes when trying to add them to the array?
