I am writing a program that is using a access DB for the info to be displayed. However when i started making the program i started by just databinding the listboxes.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'AcskillsDataSet.Skills' table. You
[Code]....
but now that im looking at the data this is prolly only useful for simple data. Im wanting to seperate the data from queries into multiple boxes. Am i better off just manually having a connection to the database and running queries into arrays to sort the data?? The above method looks like im going to be trying to fight the databound stuff. There are two tables and the way the built in query builder is im starting to think its easier to write my own queries in variables or whatever.
I have created a setup using INNO which puts a Visual Basic 2010 Express program on the computer to update an Access database. It works on my Windows XP computer. On the user's computer, which is a Windows 7 computer, the Access database comes up as Read Only when opened. I get an "Operation must use an updateable query" error in the Visual Basic program when I try to create a record. The database has Read Only checked off in it's properties. But when you open it in Access 2010, it says Read Only at the top. (This computer has Access 2010. The database itself is in 2002-2003 format.) How can I get this database to be updateable on the user's computer? It works on my computer/does not say Read Only when opened in Access 2007.
I have a VB.Net program which reads and writes to an Access database. I am trying to deploy the program using a setup (created with INNO Setup). Upon installation on a Windows 7 computer, Windows 7 is preventing it from writing data without changing the permission settings. It reads data but it doesn't write data. This problem doesn't happen in Windows XP. My question is: is there any way to make the Visual Basic .Net program write data to an Access database on Windows 7 from the setup without the user having to change permission settings?
My software will simulate a few hundred hardware devices, each of which will send several thousand reports to a database server.Trying it without threading did not give very good results, so now it's time to thread.Since I am load testing the d/b server, some of those transactions will succeed and a few may fail. The GUI of the main program needs to reflect this. How should the threads communicate their results back to the main program? Update global variables? Send a message? Or something lese?
Now, if I update only at the end of each thread then the GUI is going to look rather boring (and I can't tell if the program hung). It might be nice to update the GUI periodically. But that might cause contention, with threads waiting for other threads to update (for instance, if I am writing to global variables, I need a mutex, which will block each thread which is waiting to write).
I'm new to threading. How is this normally done? Perhaps the main program could poll the threads, instead of the threads iforming the main program?
I'm trying to add a string to a access database, for a column that was originally designed for numbers, i have changed the data type under the design view from number to text, yet I still get a error saying that it cannot convert the string expected int32
Input string was not in a correct format.Couldn't store in Parent_ID Column. Expected type is Int32.This is the full exception, i would have put it into code display but the option wasn't there
System.ArgumentException was unhandled Message=Input string was not in a correct format.Couldn't store <A-238> in Parent_ID Column. Expected type is Int32. Source=System.Data StackTrace:
How I make SetUp for program in vb.net with local database(data base which include in visual studio.net 2008) to make it work in other computers which not have the visual studio 2008?
m using Microsoft Visual Studio Basic 2010 and im fairly new to it. Im trying to make a small program for feedback and send it to my e-mail. I have seen e-mail sender tutorials on youtube but thats not really what I am looking for. Im looking for it to be automatically sent to me, not having to type in "To" so as if its hidden I guess. So Basically
I coded a program to access a Microsoft Access 2010 database. The program is written using Microsoft Visual Studio 2010. I get the error message that the database I'm trying to access is in an invalid format. look at the code below to see what I missed. The error is in the datasource statement.
I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003 Search in file Pokemon Dex Numbers 003 returns Bulbasaur Check Bulbasaur base stats in the base stats file etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI? -Databases would load internally? -I could search a database without having to load it into like an array or something?
This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields
For those of you that have been helping me for the last two days thank you first of all, my program is now at the stage where i need to have a windows application that the user can then select databases from, and then using these databases information will be put into a second application that will then run a program to compute some data and spit it into a .xml file.
Is there a prewritten piece of code for choosing databases? And then a set format for choosing cells in that data base to be exported into another windows application?
I want to create program in vb2008 express with ms access database. Can somebody help me so i can learn how to program using classes hard coded. I have learned vb6 before but it has a big difference on vb2008.
I have a database named "DATABASE" in ms access 2003 and the details are: Table :
All the CAPITALIZED name are Table and all items inside the parenthesis are fieldnames. I don't know where to start on working on this RECORDS. I was able to understand visual basic 6 a bit, and i am trying to apply the coding to VB 2008 but all i get is errors. I am hopeless now and i need help to be able to start my programs. If someone can give me a sample code, i think i would be able to trace the line of code to be able to understand it. I am currently an inventory manager on the small company i was working with and i like to organize my record by using database.
I have a access database named login.mdb,which has many tables.i want to update table named "try".in tat table i have two fields viz name and rollnumber.i want to update rollnum of corresponding name.[code]...
1) I want my database should save on default location unlike this:
Dim connectionstring As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Contacts3mycontacts.mdb;Persist Security Info=False"
Since i'm deploying my project on another computer itz showing me an error of database connection.Then again i've to make one folder of Contacts3 in C drive and then itz connecting the database.please let me know how can i deploy my database as default.
2)When i'm deploying my project on server itz not running and the same pfoject is running on different computers.Itz showing me security errors.
I have a windows application written in VB.net. After finishing it I'll setup the program in more than one pc. I want to connect the program in all PCs to one database in another PC using Microsoft Access, and I also want to limit the level of access of the users to the database in my program.
i an encounting this problem that is...my database is unable to access in client pc and its comes out this error: cannot open database "synonym" requested by the login.The login failed. Login failed for user 'SIDNEY-U1KECH4Tsidey'.
I have started a little program which is linked to an access database, and it basically allows the user to input a name and a picture, with the file path stored in a text box and the picturebox getting the picture location from said text box. At the moment I am using the BindingNavigator to go between data. Everything works fine, however, whenever I press previous or next, the picturebox loads up the picture using the file location of the previous datas picture field. How can I tweak this so that when I press next or previous it loads the picture into the picturebox using the file location of the data I am going to, not coming from? [code]
Im building a program that's linked to a ms access database. the function i use to update a row... In order to save a lot of typing i inserted a for loop that uses a directcast function. i did this because i have numerous text boxes that i name tb1, tb2, tb3, tb4...etc and they each correlate with row 1, row 2, row 3, row 4...etc in the database.[code].....
I finished my application whith vb2010, this application uses a Access database. I have a problem because when I install my application he put database in de same path "program files" and this path is only read And my application crahed. I know how to installer put database in other path but I don't know how to tell my application to find this database.
i wanted to know how to deploy a simple program that is coonected to a access database.I have tried it many times but when I try to install it says that some file is mising. How can I do it so that I dont have to copy the database from one computer to another.
I am building a windows program that I need to link to add and pull information from an access 2007 database. I really so not want to use SQL if at all possible.
I made a program that i want to run on computers at school and it utalizes a MySQL database. When i try to run it the program does not work as it cannot access the database. I open the code up on my computer at school and it has errors saying ti does nto recognize the MySQL code as it does not have it in its .Net library. So i try to download it into the library but that does not work. So my question is, will programs using any kind of database not work unless the user installs the needed add on, weather it be a .Net library add on or a java add on for MySQL? That cant be right it.
I start program for a library and I have to use Treeview and Access DataBase..I find methode to load database to treeview but the problem is save changes after I run program Access Database load to treeview and I edit tree but how I can save changes before I close program?
I've seen used the datagridview to save the changes.
I don't use a dgv, but rather I connect directly to access and when a text field has text in it, it takes that text and searches, and updates various text boxes with the according information (finds a row, and takes all the data in the columns and adds it into their respective box). There are approximately 5-7 text boxes being used at the same time, and only a few will be changed.
How would I go about updating and saving through the VB program?
Here are some relevant pieces of code:
Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.jet.oledb.4.0;data source=C:\InventoryMusic.mdb")
1. Private Sub BooksBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BooksBindingNavigatorSaveItem.Click
I'm having a problem with some code which seems to stop my program from working correctly. Below is my (i have only added to code which i think you will only need to see.
Dim con As New OleDb.OleDbConnection Dim dbprovider As String Dim dbsource As String
