I am using VB 2010 Utimate on a Win7 64bit machine. I have an accdb database created through MS Access 2010 (database has a password). How do I go about connecting to it using codes without having to drag a database control on the form, also is it possible to code my form so that it will automatically detect the path of the accdb database? Also I want to view the whole table using datagrid view as well as perform database actions such as add, edit, del, save, search and etc.
View 7 RepliesFirst, I would like to add a text box search field to this form (because navigating through several thousand users with arrows isn't going to work). When the search button is pressed, I want the username to be looked for. If found, the form (and each textbox, option button, etc.) is updated with that user. I can then modify the user's information and press save.
Second, how do I access and change information in a database with only code? For example, if I periodically want to check every user in the database to see if they have over "100 points" and if they do, I subtract 10 points from that user.
I'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.
Code:
Public Sub LoadCareer()
Public rs As New ADO

View 3 RepliesI have to deploy my VB.NET application, and create a new access database with 5 tables, some filled in with values on installation in a specified folder in the C: drive which also needs to be created. I have found using google havent seemed to work for me. I am using Visual Basic 2008 Express Edition, so maybe I need to use a proper copy of Visual Studio 2008 to do this.
So basically I am looking for a way to create a .exe file that will be used to install my program on a user's computer, and create a folder and database with some values on instalation. Could anyone tell me how I can do this or point me in the right direction? EDIT - Also would you be able to answer this question for me. Will the computer that the program will be installed on require visual studio or any other software to run my program?
I'm creating a database using Access 2007 and Visual Basic 2008.
I'm using the try and catch exception handler in my project. this try and catch are inserted in the Save Record button. here is the code snippet of my try & catch:
CODE:
My problem is that, whenever i add a new record and clicked the Save Record button, the msgbox "Data Update Failed" popped out. But when i recheck, the newly added record was actually successfully saved in the database.
Is there something wrong with my code? The new record is inserted in the database but why does the "Data Update Failed" msgbox was popped out instead of the "Data Saved" msgbox?? I've tried many times but i still cant figure this out. please help.
I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?
View 4 RepliesSo i'm creating a simple application as an example that is to link to a Access 2007 database.
On my main form i have four listboxes that are correctly attached to the table, I have one for First Name, Last Name, Phone, and School. I added 3 records to the database in Access to see if I could display the records in the listboxes on the form. I found that it was very easy by setting the properties and I have no problem there. I also have a command button that loads a new form for the purpose of adding a record to the database.
Here is my main form (frmMain.vb)...
CODE:
And Here is the code for the form...
CODE:
What i'm looking for is when the user presses the Add button on the frmAddNew form then it needs to close and the new record is listed in the textboxes and saved to the database. Id also like to know all kinds of things i might be able to do with textboxes and databases because i'm trying to learn for a larger project where i'll need to keep track of hundreds of records.
I understand that this is a simple procedure, but i've been spending all night scouring tutorials and getting lost in the msdn library online, so maybe some human input will be better.

I've installed the Microsoft Access Database Engine in order for an app to read and update and Excel file using OLEDB on a 64bit operating system. It all still works fine on 32 bit however i get a "Failure Creating File" error on a 64 bit machine.I'm using the following connectionstring(VB.Net) as per [URL]:
lstrConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C: empexcelfile.xlsx;Extended Properties=""Excel 12.0;HDR=YES"";"
Visual Basic Project - Student Check In Form using an Access database backend This form needs to draw information from an Access database containg tables for STUDENT, INSTRUCTOR, and SECTION. These all need to have primary keys and ids. When (the user) clicks on the drop down box that displays all the sections:
{Table Tennis 1, Table Tennis 2, Table Tennis 3, Billiards 1, Billiards 2, Billiards 3}This should populate the listbox or datagrid from the STUDENT table with the Students that have the same SECTIONID as the SECTION selected in the drop down menu above.
After the Student list has been populated (the user) clicks on a student name in the listbox/datagrid and this inserts that student into the CHECKEDIN table that has a datagrid/listbox associated with it.
This is a great project to practice connecting a database to Visual Studio 2008 .net and playing with the data that has been pulled in. You could use SQL instead of Access.
i recently received a new work pc and have installed visual studio 2010 premium on it. this was installed on my old machine as well, the only differece between the two PCs being my old one was 32bit and the new one is 64bit.With that said, when i create a windows form project and drop a control on a form, double click that control, the default event code is created for me.It is missing the "ByVal" portion of the code. Using a textbox as an example, below is the code it generates. Is there a setting that I'm just missing and need to turn on? I've been using visual studio since version 2005 and i've never seen this before.
Private Sub TextBox1_TextChanged(sender As System.Object, e As System.EventArgs) Handles TextBox1.TextChanged

I'm sure there is a good tutorial somewhere on the internet. I'm okay with doing it with designer, but now when I have a situation where I can't use MDI container but tabcontrol.Other solution would be to make a MDI container out of tabcontrol. Is it posible or only other form can be MDI container.

View 5 Repliesmake a program in VB.net Ultimate 2010 that will take screenshot of the current desktop and save it to MS Access Database 2000 in a single click of button.
The challenge is the form. Form must be hide first before taking the screenshot so it will capture only the current desktop. After that, it will automatically saved to the MS Access database 2000. I hope someone can help me out of this stuff.
it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!
