1. Open program.
2. Click on a record in listbox1 (It then put all date of this row in the textboxes)
3. Change/ edit info in textboxes
4. Click on edit button.
It does not update and when it updates it does not put all info in, or dit makes a new row of data.I don't want it to make a new one, it must update it.

I have a small and simple program. I am accessing an Access 2003 database that has seven columns:
ID-AutoNumber (3) - Primary Key
Business-Text (40)
Address-Text (40)
City-Text (20)
[code].....
In VB, under Data Sources, I set five to textbox and the last two to linklabel. I then dragged each to my form. When I run the program, everything works, navigation and data displayed. However, I have not been able to figure out how to have the URL and Map (linklabels) when clicked to open into a browser. I have found many sites on the web that gives me example code to hard code one specific linklabel to be presented as a hyperlink, but have not found a solution to making a linklabel a hyperlink when the data is filled from an Access database. I am also trying to figure out how to mask the data. For example, I want URL [URL] to display as Homepage, and [URL]to display as Directions.
This might seem like a silly question, even for a newbie but I can't access the members of a class from a user control.

I have a form and some controls as dropdown and textboxes..
The situation is that when the form loads, i want the value in textbox to be incremented, everytime it loads..
This is something i tried.. I get the value '1' everytime !! It shows no sign of increment..
However, i also want it in the format 0001,0002 if possible..I tried something like this..
Private Sub Order_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
textBox1.ReadOnly = True

Is it possible to pass data between a MODULE in Access and a VB2008 app?
To be more specific, suppose a VB app calls a MODULE in a access DB and the job of the module is to count the number of records that have "Joe" in a column. I know this can be done with a SELECT within the bindingsource BUT in some instances, it is much faster to pass the task to Access and return the result.
So - can an Access MODULE RETURN a value back to a VB app?
The Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?

I've got this program I'm working on in VisStudio2008. Basically, it accepts a password and executes an Access 2003 database using the Access 2003 runtime. I've got the thing looking up a password and all is good, but there's one problem those annoying Access 2003 and higher warnings about unsafe macros. Does anyone know a way to make sure those don't show up when the program starts?My client has a database that someone else wrote for her. She's not at a point where she could have it rewritten (believe me, I've tried to talk her into that). So I have to stay in Access but it's not very professional to have those warnings come up.

I have a access db that contains logs in it from a project of mine. I have set up a total of 10 columns per row for log ids to be inserted ex: Log_1, Log_2, Log_3, etc...
The logs are pulled from an XML file that I downloaded and extracted from in an array list: log_id_1, log_id_2, log_id_3, etc...The db columns are a fixed number, 10. While the log id in the array list are variable, from either none upwards to about 20 of them.
If my arraylist has more entries in it than db has positions, I dont get an error, but if my array list has fewer than the 10 fixed columns in the db, I get an index error.What should I do to fix the error, capture the error and ignore it or is there another, better method?

I'm having trouble updating my access database using DataGridView1 on my form. I created a DataGridView on my form linking it to an access database data source. At run time, the DataGridView shows the content of my access database. When I edit the database data in DataGridView, it looks like the database is being updated but when I close the form and reopen, the database is not updated. Do I have to write code and assign it to a button to update the access database? Is there a way to update the database once a new value is entered in the DataGridView? Am I missing a setting that does this automatically?

View 1 RepliesWe are working on an asp.net 2.0 web app that emails users an ical to save to their outlook 2003 calendar. We noticed none of the code to update or delete an item seem to work even though the ical 2.0 spec supports it. We are curious if Outlook 2003 just ignores this?Does Outlook 2007 act differently?We have situations where an event may change or be cancelled which fires off an email notification but the updated ical just adds a new event, it nevers deletes and or moves the original.
View 2 RepliesI'm using Visual Basic Express 2008 to create an interface with a order database in MS Access 2007 (.accdb file). Everything is fully functional except updating the "Inventory" table is very slow. Updating around 2200 items takes almost 2 minutes and the window will appear as "not responding" for the duration if you click away and come back. Here is the process:1. Tab-delimited text file is picked by user, which includes all inventory items (not just new ones)2. Each line from text is parsed and read into variables (tempSKU, tempItemTitle, etc.)3. Old items are updated and new ones are added. -> This is the bottleneck
I used to have a series of IF statements to check which elements were changed and report them, but that was about 2x as slow. The new code is a little faster but doesn't provide the feedback I liked (update part is commented around):

View 2 RepliesI have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.

I'm doing database development in Access 2003, and the Visual Basic portion of it is acting up. It seems to be "refreshing" itself constantly. Two very frustrating problems are occurring because of this: 1) Intellisense for properties and such pops up but immediately disappears and turns red and 2) it's automatically checking the syntax of lines before I can finish typing them.
The problem seems to be intermittant. Some forms in the database operate fine while others immediately turn the line red two seconds after I start typing. I am having this problem on both of the computers that I use on a regular basis.
i have a database in access 2003 and i submit a query to a specific table. The fields of this specific table (STOCK_PRICES1) :
DATE --> type date (d:M:yyyy)
CODE --> type text
OPEN --> type single
HIGH --> type single
LOW --> type single
[Code]...
i receive an error. Why? Conflicts between access 2003 and vb.net 2010? SQL Server is better?And another question. My Regional settings regarding the date is d/M/yyyy but in my vb.net example, the @date1, @date2 parameters accept M/d/yyyy dates. Is there a way to define into the parameters the d/M/yyyy specification?
The limit of an access database. Because I only know of manipulating access 2003 database with vb.net. And were going to make an information system for a small hospital for our project.
