?write A Program To Call Quickbase And Retrieve A Database And Put It Into An Array?
Feb 9, 2010
I'm trying to write a program to call Quickbase and retrieve a database and put it into an array. It's a contacts table that I need to be able to query and select different fields according to letterheads, memos, etc. I've tried to do this three different ways.
1.) Find a direct port or some way of accessing Quickbase directly, similar to connecting to an oracle database or MS Access.
2.) Export the table to MS Excel and read the data from a spreadsheet.
3.) Opening a web browser in a background processes and login to the Quickbase account, then navigate using the little XML knowledge that I have.
I just can't find a good way to do this. Any ideas or can give some help on the code to do any of the ideas?
i need to make a database application that can write/retrieve cells/datasets from/to a database i buyed a book in there was an example of how to create a database application while debugging i had the "Object reference not set to an instance of an object." error and it highlighted this code
objDataRow = objDataSet.Tables("KlantenTable").NewRow now the problem is here i declare something later in the code i write to it objDataSet.Tables("KlantenDataTable").Rows.Add(objDataRow)
I'm currently designing a mock-up of a customer booking system for a cinema using Framework 4.0. All data at present will be stored in an array and as it's a mock-up, it will remain their (customer name, ticket price etc...) as no requirement to permanently store the data at this time.[code]...
Should be pretty simple for a pro. i have images in sql server database and i want to retrieve them in my aspx (vb.net) file.i have in aspx this image control -in vb.net i have started this [code]..
I have to write a program for a user to take a 20 question test (A, B, C, D). The users answers will be stored in an array and compared with a 2nd array that has the correct answers. Its then supposed to go to a 2nd form when you click show score, grade it, and display whether each answer was right or wrong. I'm missing something easy probably.
How can I save a date data type from vb.net to access that access have date/time in its data type and how can I retrieve it? I also want to use datediff to auto calculate the age to be shown in a textbox.
I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long
After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.
The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single
I have a program that creates an array of part numbers. I also have a database that holds part numbers and all associated information I need for other calculations. How can I search an MSAccess database table against all of the part numbers in the array? The Array will never have more than 100 items in it, the table has over 7000 records to search from. I've posted my nonworking code hoping someone can point me in the tight direction.
Dim rs2 As New ADODB.Recordset Dim Test1(7000) As String Dim Test2(7000) As String
I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.
I then run the following code:
If ConnectToInformix() Then Dim cmd As New IfxCommand("dc_routeHasOutstandingQuantity", conn) cmd.CommandType = CommandType.StoredProcedure
[Code]....
This error does not occur when calling the stored procedure from a live SQL connection.
I'm trying to put together a quick program for our database, I haven't touched VB since vb6, and we have 2008 .NET now. my question.
Ideally I'd like to make an array which can hold multiple values...such as
Job[job#].joblocation Job[job#].jobsupervisor
So there would be a Job array, and then different values contained within that. I can't seem to make an object or whatever which allows me to hold different variables inside it.
I have a byte array of a file and I need to save it into my database in a field that has been set aside of type image.
However I have a problem my data access class takes a sql string and commits it to the database for example.
"EXECUTE stored proc @parm1, @parm2, @parm3"
However the problem is I cannot figure out how to transfer the byte array to string so that I can add it as an argument.
I hope this make sense.
I also understand that I can build parameters in com objects but I do not want to do this as it will disrupt my whole data access class and I am not prepared to do this at the moment.
I'm new to LINQ and am having a problem getting proper results from a simple (working) stored procedure that takes no parameters and returns a single Integer. When calling this sproc with LINQ its returnvalue is always 0. When run using tableadapter or directly on the sql server it works, returning 6 digit values like 120123.
Here is my LINQ code:
Dim MeetingManager As New MeetingManagerDataContext Dim MeetingID As Integer = MeetingManager.NewMeetingID().ReturnValue Here is the NewMeetingID procedure: ALTER PROCEDURE [dbo].[NewMeetingID] AS SET NOCOUNT ON BEGIN
I have been set the task of providing a small forms app to interact with Sage Line 50 Accounts database.
Before I get started though I wondered if anyone knew if you can use VB to retrieve and write data to and from the database and if so how? I read somewhere that it's ODBC?
My office BA requested me to develop Window application to retrieve all the files from the SalesDepartment folder : F:SalesDept and write the name of the file into a TextFile and save it into this folder F:StoreFileName
I have not written this type of coding before and I need your help to show me sample coding in order for me to learn something new.
I've written the following code which works fine.I'm wondering if there is not a simpler way of writing it to achieve the same?

I've not found any other way than using a Timer to have the status updated and the other actions done, as as soon as I start the thread, I loose control and "GetList_Button_Click" does not wait or control the thread.
The goal of using the thread is to not freeze the application and also adding a button to cancel the search in the future.
I'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods Dim foods() As String = IO.File.ReadAllLines("foods.txt") Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click
I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format. I mean user can retrieve value in any numeric array type rather than specifying an array type. E.g.
I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.
I need to retrieve data in array. We are asked to get id number, name and section and put it in a array and then if we clicked retrieve button it will prompt an inputbox requesting for the id number of students and after we input the id number of the student the name and section will be in the msgbox.
I am trying to teach myself programming and I am on the subject of arrays. I want to create a simple program that asks the user to input 5 numbers and then outputs those numbers to the user. The program is a console application and I'm using Visual Basic 2005. My code is as follows:
I have a datatable with one column, I am trying to retrieve the values in the table into a string array using linq.
Dim dt As DataTable = DataAccessManager.ExecuteSelectQuery(selectStr).Tables(0) Dim strArr() As String = (From dr As DataRow In dt.AsEnumerable.AsQueryable _ Select dr("MASTERID").ToString()).ToArray()
I get an error "Range variable cannot match name of a member of the 'Object' class"
how i can write a program to create a shortcut in the startup folder of a different program. So i have one program on my computer that should run at startup, i just need another program to create a shortcut to it, and then copy this shortcut into the startup folder.
I'm trying to call an array from another function into an argument command for a command prompt, but I have no clue on how to do so.This code is the code where I am calling the command prompt and adding arguments
Private Sub ConvertButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ConvertButton.Click Using m_Process As New Process()
i have to write a program for my VB class that consists of a resistance checker program. I've searched like a madman to help me through this and I have found nothing >. The program consists of 2 combo boxes, the first one is the nominal resistance drop down list of the numbers :100, 150, 220, 330, 470, 680, 820 and 1000. The second list is of the tolerance numbers; +/- 0.4%, +/-0.6% and +/-0.8%. Now what i want to do is select a number from the first combo box and select the tolerance level of the second combo box and i input the resistor of said value into the text box. when i click the check resistor button it should display a message saying if the resistor is in or out of tolerance. For now I have the form all laid out and the values inputted into both combo boxes and i can go to run the program i am able to select said values. Now my problem is trying to get the right code so that i can check the resistors value.
