I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.

Just wondering if there is a way to jump to the next item in the Items List. Im sure most will proberly be asking why not ust use the else statment, but to me wrapping the "Do Something" code seems to be less readable especcially, when there is a lot more code.
I have developed a custom assembly for checking for SQL Injection Queries on webpages. The .dll reads a text file of key words. Does a for each loop to check a sql string against the key words. If one is found it returns true, otherwise it returns false. This works perfectly on 99% of my web pages and class files, however, I have one page where I call the assembly and the loop only finds the first keyword and stops

View 6 RepliesI have an ini File which I use as an "index" of jar files. The Jars are declared in it like:
Name of the jar=c:Path
So when my application starts, the ini file gets loaded in a list view. I have a delete button, with which I want to delete the jars from the list view and the ini file. It must be possible to delete multi choiced jar references. so I thought to do it with for each, so that every selected item get searched in the ini and deleted. The Error is, that the String (is correct, I tested it with a messagebox) get analysed - Unknown escape sequence R (The error is between the ** **)

Private Sub jarDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles jarDelete.Click

Is it possible to define my list of strings like in 'good old' VB60, to use only on ebyte of memory for each character? .NET always seems to store any string as unicode, which doubles the required memory. The case is that I have a huge list of strings, all of the same size. It is about 50.000.000 items, 12 characters each. You can imagine I am running out of memory in no time. I tried converting them to arrays-of-bytes but in that case I loose the possibility to perform a "LIKE" statement in a FOR-EACH loop to check for a specific item.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

Was wondering if there's any way to "skip" every other item in a For Each loop? For example, say I have an array consisting of an unknown number of strings. So the first 5 strings would be...
"String 1"
"String 2"
"String 3"
"String 4"
"String 5"
But I only want the For Each loop to process "String 1", "String 3", "String 5", etc., etc.
