View 3 RepliesShould Change File From Binary To Text Or Another Type
Apr 20, 2011i am currently doing a project for my course. My project is creating a system for a mechanical workshop, this includes customer information, car information, expenditure ect. I am not allowed to use access to store the information as this will decrease my overall mark on difficulty hence i am going to use files to store the information. I am using VB 2005. I have tried with binary files, this was good at first as it stored data in a record but then when i tried to create a algorithm to search the data it failed.
1) Should i change my file from binary to text or another type?
2) Anyone have any ideas to search within a binary file? If you do can i get some code please.

Create An Application That Allows User To Type In A 32 Bit Number Using Binary System
Jul 13, 2011Can anyone help me to break down the instructions for this assignment.Create an application that allows the user to type in a 32 bit number using the binary system, and convert that number into the decimal numbering system.For example, the user types 000000000000 0010 (where there are 30 leading 0's, 1 then 0 from left to right), and the output would be 2.The user will type a string that is 32 characters in length.A For loop 'reads' each character using the x.substring(i,1) where i is the current character we are reading and 1 means one character only,and x is the entry the user typed (use a Textbox to get the entry but Inputbox is also ok).When you start at the first character (from the right) then that value is to be * 2 ^ 0 then the second character is to be * 2 ^ 1, then the third character is * 2 ^ 2, hence:( x.substring(i,1) converted to Integer ) * 2 ^ j represents the decimal value of the current number (0 or 1) we are reading.A variable is needed to accumulate all those values.After the loop is done, display the accumulated value.To test this code on a simple version, enter a 4 digit binary number, where 0010 is decimal 2, 0110 is decimal 6, 0111 is 7, and 1000 is 8.
My understanding is the user must enter 32 digits into a textbox. The textbox should place limitations that only allow the digits "0" and "1". This error could be displayed to the user with a messagebox that then asks to reset the value orginally inputted into the textbox. My understanding is I should continue creating the formula of the position of each character where the third character is *2^2, fourth is *2^3, fifth is *2^4 and so on? I don't understand the formula and how it works.

View 1 RepliesUsing FindControl To Target Literal
Jan 5, 2012I have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such:
Dim orgNameString As String = getOrganizationName.getOrgName(organizationID).ToString()
Dim myOrgName As Literal = FindControl("orgName")
myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal)
If Not (myOrgName Is Nothing) Then

.net - Escape The # Character In A String Literal?
Dec 10, 2009If I needed to escape a double quote character within a string literal I'd use two consecutive double quotes as follows:
Dim name = "Chuck ""Iceman"" Liddell"
However, it doesn't seem like consecutive # works the same way. The compiler is expecting a compiler directive to follow the # character, even when its enclosed in double quotes. How can tell the compiler that I want a # character in my string?
EDIT: as a few of the answers below point out, # is not a reserved character. I closed my solution in Visual Studio and re-opened it and no longer got the compiler squiggles warning me.

Comparing An Object To A String Literal?
Feb 2, 2011This might just be a matter of taste, but I'm wondering if there's a "recommended" way to compare a variable of type Object (which might be Nothing or have a different dynamic type than String) to a string literal in VB.NET. The following options obviously won't work:
If myObject = "Hello World" Then ... -- won't compile
If myObject Is "Hello World" Then ... -- tests for reference equality, which is just wrong
If myObject.Equals("Hello World") Then ... -- throws an exception if myObject is Nothing
If DirectCast(myObject, String) = "Hello World" Then ... -- throws an exception if myObject is not a string
Thus, the only (simple, single-expression) solution I could find is to use
If "Hello World".Equals(myObject) Then ...
which looks a bit clumsy to me. Did I miss any obvious alternative, other than doing type checks or explicit checks for Nothing?(Of course, we're talking about Option Strict On.)

Pass An Array Literal To A Sub Routine?

Define A String Literal Containing Non-ASCII Characters?
May 19, 2010I'm programming in VB.NET using Visual Studio 2008. I need to define a string literal containing the character "÷" equivalent to Chr(247). I understand that internally VS uses UTF-16 encoding, but when the source file is written to disk it contains the single byte value F7 for this character.
This source file is processed by another program that uses UTF-8 encoding by default, so it fails to interpret this character correctly, attempting to combine it with the following single-byte character. What encoding would correctly interpret the single byte F7 as the single character ÷?
Alternatively, is there a way of expressing a non-ASCII literal that uses only ASCII characters - like using some kind of escape sequence?

View 1 RepliesASP.NET Custom Control - Template Allowing Literal Content?
Jun 16, 2010I want my User Control to be able to have Literal Content inside of it. For Example:

Currently the code for my user control is:
<ParseChildren(True, "Content")> _

And when I put text inside this control (like above) i get this error: Parser Error Message: Literal content ('Please enter your login information to access CKMS:') is not allowed within a 'System.Collections.ArrayList'.This control could have other content than just the text, so making the Content property an attribute will not solve my problem.I found in some places that I need to implement a ControlBuilder Class, along with another class that implements IParserAccessor.Anyway I just want my default "Content" property to have all types of controls allowed in it, both literal and actual controls.
ASP.NET: Handle A Click Event From A <a> Element Within A Literal.text?
Feb 9, 2012I'm creating <div>'s and appending them to a literal's text property. I have added a <a> element to the text so that the user can click on a specific element. How can I tie that to a function to handle the event in the codebehind (vb.net) ?
Example of my Literal.Text ...
For Each row As DataRow In oDataTable.Rows
MyLiteral.Text &= "<div style='font-size: 8.25px; text-transform:uppercase; padding:3px; background: #FF8C00; border: 1px solid #000; margin: 0 5px 0 5px; display:inline-block; float: left;'>" _
& row.Item("LastName") & " | <a href='#?"& row.Item("ID") & "' style='color: #000;' >X</a></div>"

So the above code I want to somehow allow the user to click the X link and then it would remove that person.
