consider the following code and comments:
Console.WriteLine(1 / 0); // will not compile, error: Division by constant zero
int i = 0;
Console.WriteLine(1 / i); // compiles, runs, throws: DivideByZeroException[code].....
This test seems to corroborate the idea and a literal double of 0.0 is actually a very, very tiny fraction which will result in Infinity...
Is there a function in VB.net that allows me to divide a really long String into a specific number of characters? [code] The length of this string is 18 and I'd like to group it by 3, so each group would contain 6 characters. Is there an easier way of doing this? Is there a predefined function in VB.net? I'm already thinking of doing it manually, like converting the string into characters and storing them inside arrays.

i have two textboxes where a numeric value will get entered into both, these values will then be taken and the first value divided by the second value. The problem i am having is that if for example the first value is 11 and the second value is 10, when i divide 11 by 10 the result is 1. I have tried setting the output format to have 2 decimal places but it still displays 1 instead of 1.1. [Code]

Halo, may i ask how can i save my answer fault into database after i done division. I am taking the data from textbox(input data) and done the back coding division.
If
strOperand = "/" Then
intLast = intFirst / Val(
Me.TextBox1.Text)
I'm not getting a remainder like I would have hoped. I'm new and I'm sorry for the lack of intelligence on the subject. To my understanding the Val( function will convert the string to a number, but when I divide it gives me a single number instead of an integer.
Let say I had a project contains 10 forms and 10 reports and typed dataset (xsd)I am trying to divide my project forms into dlls, so when the client had a problem or asks for modification in single forms, I had to build the project all over again and the exe size will be large.
in my current project, the exe size is 4.8 MB, and I am working with customers by internet and remoting, so every time I make small changes (change the back color of textbox in one form) I had to rebuild and send the whole 4.8 MB to the customer. And not forgetting the increasing size of the exe with time.I know that converting my project to class library and built it will convert it to dll, so I had to create a second project to manage it.
1 - Can I convert 3 or 4 forms / 10 forms total in my current windows application project to dll?
2- What is the best recommended method to divide the project into smaller entity.
why I am having attempted to write error first with my form generating an excel file. Then lately, with my other forms?

I tried to experiment with the ability of .NET to support unions using the code below,but it causes a System. ExecutionengineException in .NET 2.0 and FatalExecutionEngineError in .NET 4.0 with the message:
The runtime has encountered a fatal error. The address of the error was at 0x738b3138, on thread 0x1080. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug
include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.I agree that this code should not work, but I didn't expect this kind of exception. Is this a .NET bug?

View 2 RepliesI'm getting this error only on my laptop (so far) trying to get the local IP address. I've tried 3 different ways of getting the IP address and each one fails with the same error. This has never happened on my desktop machine but when I moved it to my laptop for additional testing I started getting the error and it further states "This is often an indication that other memory is corrupt". It does however retrieve the ip address but I'd like to get rid of the error. Here's my code and I might add that it never takes the catch ex path in my try-catch code it just stops on the error when running in the IDE.

i found out that the program wants to use a part of the memory that he may not use.In my case it only happens when i want to print something.In there i have a PrintPreviewDialog and add a PrintDocument.After that one is loaded it shows the document on the PrintPreviewDialog.Most errors that appear show drawing errors.So, how can i tell windows that the program may use the memory?
A friend of mine thought it was something like this:

I have a Windows application written in Visual Studio .NET 2008 in Visual Basic using the .NET Framework 2.0 A couple clients have been experiencing this very frustrating (but random) error "Attempted to read or write protected memory..." message. I've identified the code specifically when trying to create a new object from a VB6 DLL. [code] The new event of the VB6 object has no code. The error is very random, seems to work more than 99% of the time but every now and then throws an error. Same workstation and user can run the same code numerous times without any issues but eventually the exeption is thrown. I'm at a loss on this and it cannot be reproduced on demand.The VB6DLL is marked COMSelfReg in the MSI. The VB6DLL has not changed but the error seems to be new in the last few weeks. Reinstall the app and the VB6DLL does not resolve.
