It will work with any form of text input, my articles focus on this, please take a look. The code above, while correct, also blocks space bar, back space and various other functions such as copy and paste.

Be careful with this because it alos blocks out backspace and space bar.

Abstract Class in vb.net is a MustInherit Class means which cannot be instantiated you cannot create the object of an Abstract class, you have to inherit it in some other class provided that its not an abstract class also in order to create an object of it. They are basically only used for implementation of base classes.
Hope it helps !

Thanks for the reply.
What about the Interface. Can you please give one simple example for Abstract ?

Interfaces allow us to create definitions for component interaction. They also provide another way of implementing polymorphism.

By query strng, do you mean the SQL where the data comes from ? Are you using ASP.NET ? The query strng is how varibles are passed on the URL of a web site.

You can use the DataAdapter to execute a particular query then fill the dataset and use that dataset as a source to fill the DataGridView.

I need to write an application that reads a text file from the mainframe and store the information in a sql table. There's no space, comma or anything that separate the field and content of the field in the text file. I don't even have any idea where to begin. Pls help
|
|
|
|
|
start with being able to get the file off the mainframe. if you can't do that then parsing out the file doesn't come in to play
|
|
|
|
|
So far I have managed to take out the file from the mainframe and stored it as a textfile.
|
|
|
|
|
1) get file off of mainframe - done
2) can you read the file into the program?
|
|
|
|
|
Yes I have written a code to read the file into a program and creates another folder and write the contents of the file
|
|
|
|
|
1) get file off of mainframe - done
2) read the file into the program? - done
3) you say there are no delimiters that you can key off off. that implies these fields are fixed in length. so create your parsing routine for each line read in that breaks it out based on the length of the field.

Hi all,
I have a C# class with .Cs Extension. Now I want to use these class method in my VB.Net application. How can I do this without creating DLL
Thanks in Advance

Translate the code into VB.NET???
|
|
|
|
|
You have two options.
1) Add the C# project to your solution and compile it into a .DLL that your VB.NET project references.
2) Translate the C# code to VB.NET and integrate that code into your VB.NET application.
|
|
|
|
|
You can not mix .NET languages in a single executable (EXE/DLL) file.
Hence, two source languages will result in at least two executable files.

I think there is an obfuscator that also combines assemblies. I'm not sure if it works directly in VS (meaning it produces output from the other projects in the solution).
