I have an access database which includes Customers table and one of its columns is the Birth date. In project in visual studio, using visual basic 2010, I have a form with a calendar. In this form I want to show who has birthday today. How can I compare all the customer�s birth date with the day we have today? And have as result a label with all birthdays?

This question appears to have died, so I've decided to offer a bounty.What I'm most interested in knowing is if my scenario in the ETA1 below is viable and is used. If it isn't, then a good explanation of why not would be a good answer. Another good answer would be an alternative (but not including the internalsvisibleto attribute).
The best answer would be, yes, it's viable, everyone does it and customers love it!ETA2: I think I've thought of a good solution. I provide the customer with a distributable edition that is as functional as their edition but is unlicensed and has the classes and members hidden, using attributes.
I can do this with compiler directives, on every single important member, but I wondered if there was some global way to hide all members of a class?
A simplified scenario I have a class that extends a control in someway and I want to sell my class under two licenses;
(1) Standard - The customer gets x number of controls that use my class but can't instantiate the class (its internal).
(2) Developer - The same as Standard except they can create their own controls that use my class.
My problem is that when the developer customer comes to sell their controls, they can't help but expose my class to all their customers.
The only way around it, in my scrambled mind, would be for the developer to somehow integrate my assembly into theirs, and in that way I can keep the constructor internal. Or, use the internals visible to attribute.
ETA1: I'm thinking aloud here, but, I could have a list of permissable calling assembly names which the customer could add to. When they ship their product, their customers' assemblies would not be in the list and therefore they wouldn't be able to instantiate certain classes. (The list could obviously be hashed).

In this program I am suppose to use data to compute a customers electric bill. My code works correctly for the most part except for two things. I cant get the loop correct I want it to ask the customer to enter readings but once it does it outputs the same information from the original time so I am wondering what I have to do to have it recalculate when new values are entered by the customer. My other issues is it is suppose to continue to ask the customer for additional readings till the value entered by the customer is -99999, when I run my program and enter -99999 it does not stop.

I'm developing a small app to for a vehicle rental company. They require the app to print invoices for customers (fuel usage and etc) with charges. I was thinking of outputting row by row to a html (file) table and populating qty,amount,final amount etc programmatically. And letting the user view and print that html file.

We have a rather large VB.NET accounting application that crashes occasionally for some customers. I have now been able to reproduce this particular almost 100% in my test nvironment using certain data. The crash happens when clicking a list box after printing a report. The form involved has a list box listing available reports. You select one or more reports from the list box and click the print button. After printing, if you click the list box again, the program crashes, with an exception that does not seem like one VB.NET should even be able to produce.The exception message is: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."The call stack is:
1. System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam)
2. System.Windows.Forms.NativeWindow.DefWndProc(Message& m) [IL offset: 0x3e]

I am hoping that someone can help me with a problem I've got at the moment using Compact Framework.Net 2 SP 2.At the moment I have a UI with a series of text boxes and each textbox displays the contents of a database field. These are shown one beneath another with a scroll bar on the right hand side of the form. Each textbox has a set width which might.I would like to adjust the height each text box based on the number of lines it is holding, the font size and the font in order to avoid using scroll bars on each textbox.[code]

I have an application I am creating that displays pump information based on customers in a database. I am using VB2008 .NET3.5.I have a combobox that has a selection for a unit of measure. What I want to happen is when that is changes the labels that have a unit of measure change to reflect the change. There are 15 labels total that need to be changed and all there names are the only ones in the project that start with a X if that helps at all.
I would like to avoid creating a bunch of labels and changing the visible property and just change the text value of each one. I have just started learning VB.NET

I made a program a month ago and i gave it to the customers.recently they report some bugs and i fixed them. when i send the new version installer to them, they have some problems running it.i used vs 2008 to write it, but i removed vs 2008 and installed vs 2010 last week. when i opened my project to start fixing program bugs it asked for convert wizard so i did it.i made changes and build it. i use installshield and i add framework 3.5 Sp1 as prerequisites.
note : i was using inno setup first time. so i changed the installer too.so i tried installing the program on my machine.i just noticed that i have only .net framework 4 installed my own system. so i have no idea how the program runs without any problems on my own system. i have even tried installing it on another machine who had framework 3.5. it it work on that too.the error shown on customers machines is related to framework version. everytime i send them a new version they have some problem installing/running it.

how to create this certain program. In short, I must calculate the velocity of a ball thrown in the air after 1, 2, and 3 seconds. The formula for this is: -16t^2 +velocity(t)+height. the height for the ball is 5 feet per-second. So after defining each textbox of 1 sec, 2 sec, and 3 secs (Dim stuff) I need the button click to run through the formula then display the result for each second. How would I do this?

I am a beginner programmer so this is basically the second time I fired up VS (not much experience). I searched the internet for the last hour but found nothing that might help me. I made sure every value is positive and changed all numerical variables from integer to decimal and I still get the error.I have absolutely no idea why this doesnt work but if I remove the "for" loop then the line written in bold works just fine.BTW this is my first post so scuze any mystakes I probably made.
