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 am writing a program which includes access to a Microsoft Accsess database.

Again this will run fine on my desk computer but will not get past the open statement on my laptop.Interestingly, if I start a brand new project on my laptop and paste this code into it - it runs correctly.

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 1 RepliesI'm new to Visual Basic. I came across a random number generator tutorial. Got it working fine and then I thought, Is there a way to get it to access a database Here's the thing
1. Generate the random number.
2. looks at the database and finds the corresponding id number.
3. Takes the field for that number and enters it into a text field in the program.
So for example the number generated is 32. Then the program looks at the database and looks for id number 32. then takes the text in line 32 and enters it into a textbox in the program.Now I have my database and the program. But just can't seam to figure out how to get the two connected like I want. I have looked and searched but have found nothing like it I am using Visual Basic 2010 and Access 2007.
I've tested an application (one that I'm developing) that utilizes MS Access database (.accdb) on a backup machine. And I consistently get an unhandled exception error saying 'The Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I suppose I get this error because the backup machine doesn't have a driver or whatever to read the Access database file. Reading
this topic titled "How to deploy VB 2010 application as a standalone without MS Access", I understand that I can just specify a prerequisite for this component (driver or whatever...) in the project designer window in reference to this page.

update access database from vb 2010?
[Code]...
I just started learning VB 2010 through a book. I'm learning vb to design a program which can manage customers of a small company as a homework. It'll store data (Company Name, Phone N. and Adress) at an Access Database. (I'm using Access 2007)
I have a little background with programming but none with databases. According to the book there is no way I can delete, add or update a data from an Access Database without installing SQL Server or Express. But this program should work at a computer which may or may not have SQL server or MS Access (Any computer with Windows OS).
After a little digging only thing I could find was Walkthrough: Saving Data to a Database (Multiple Tables) from MSDN and did every step and at the end, I can delete or add rows and change values of the cells but cannot save them (when I click save, close the program and re-open it, changes are gone).
I don't get that how can I view all the data from database without SQL server but can't save changes to the database file without SQL Server.
Is there a way to do this without SQL Server? If so, can you give the right code for the MSDN Walkthrough's Save button? Or point me to a page where can i learn the right code?

I want to connect to a mdb file but i have never did that before. i don't know where to start. heard something about ado.net and some other things.
the file is a 2003 access file if i am not mistaken. and it is shared on network. so multiple users (not too many, max 50) will use it at same time. what is the best connection to use? i have to mention that i don't want to use data controls. i want to use sql commands to fetch data and manipulate data on the form controls myself. i know there are various connection ways like strings and adapters. not sure which one is better.
I got an Syntaxerror in my INSERT INTO but i cant figure out why.

I posted this as a bug on MS Connect and am wondering if anybody else can verify the problem: I been beating my head against the wall for about 3 days and I don't think it is my problem.
Desktop computer - Vista 64 bit
Portable Computer - Vista 32 bit
vb.net 2010 express on both of them
I can not establish a connection to an Access db (either .mdb OR .accdb) on the 64 bit computer. When I try I keep getting a message that says "Format at the initialization string does not conform to specification starting at index 0." (this was typed not copied). (There are screen shots over on Connect).
I can establish a connection to a "Microsoft SQL Server Compact Edition" (.sdf) database on the 64 bit computer.I can estabish a connection to all 3 types on the 32 bit computer (.sdf, .mdb, .accdb).The 'funny' thing is that if I establish the connection on the 32 bit and copy the program directory over to the 64 bit, the prorgam loads and seems to run fine. But the %$# _(%* Wizard will not run on the 64 bit machine. Runs fine on the 32 bit but not on the 64 bit. Of course I make sure that the db's are in the location where the program expects them to be when I run the program on the 64 bit machine.
One final thing, when I am in the progam created on the 32 bit and running on the 64 bit and I try Data->Add New Data Source->Database->Dataset only two of the three connections show up while all 3 show up on the 32 bit machine. Also the connection string is incorrect for the non-sdf connection. It should include

View 4 Repliesjust if you are using Microsoft Access Data Connectivity Components 2010 in your application to read data from mdb access files, you might get unexpected exceptions and your application will crash!To reproduce this behavior the best way is to run my sample application which will allow you to see the bug directly in no time.This behavior may occur at any time, any where, but I found if you use Application.DoEvents, you increase the chance to run your application to crash.To reproduce ::
1. You should not have any Office version installed on your system (I am using Windows 7 x64).
2. install the Microsoft Access Database Engine 2010 x86 (or x64 and you'll have to set your project to x64).[URL]
3. Download and run my sample application in VB.NT 2010, and press the button, you will get it [URL]Where is Microsoft going, do you think?Should I hope to receive an official response?
