I have a Date variable startdt and a String variable hdnsdate. Suppose if startdt has the value in the form 3/1/2012 and hdnsdate has the value in the form 03/01/2012. Than how can i compare that these two dates are equal in vb.net. In if condition of my program i want to do this check. In case the two dates match move out of if loop otherwise go into the if loop. E.g A sample in C# what exactly i want.

For example, when the codes are compiled, will VB.NET tend to be slower than C#? Or are there any major features in VB.NET / C# that we cannot find in the other language?

View 1 Repliesi have a listbox that contains the words "week1", "week2",all the way up to "week52" and when i select a week from the listbox it will retrieve a value from a mysql database that will represent a progress bar value. my progress bar has a range of 0-120 and i would like to have all the weeks that have values higher than 100 to be highlighted or marked somehow, in the listbox. so my question is, "is there a way to set the background color of certain weeks in the listbox to orange based on the value that they represent on the database?
for example for "week1", the value is 114, so when the listbox loads, i want the background color of the item "week1" in the list to be orange (indicating that it's current value is higher than 100)? i know that this requires me to implement a user defined drawing function for the listbox items but i dont know where i would even start. i would like this to be somewhat automatic so that it checks the values and changes the background colors of any value higher than 100, instead of me specifying a name of the item.

I am trying to compare 2 strings from 2 listbox's, sort of a fuzzy match then output the results in a treeview I'm trying to tell it to split the words where spaces appear such as "The Dog Went Up The Hill",So that would see that as 6 words and then compare that to listbox2 which may contain "the dog went up the hill last night" which would the return an 80% match,but i just can't get my head round this, here's my code.

I'm currently pulling in records from a text file into a textbox control (see code below). I want to get more control over this by adding multiple columns and want the ability to select 1 line or multi-line and "delete selected".

note ive tried more than string.compare does it have something with return false being at the bottom of the function. becuase ive tried adding an exit function once it returns true, but still I get returned with false to make it even more frustraiting the clipboard results are test/test

View 1 RepliesI've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
DataString.Split(New Char() {";"c})
Pass through
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.

View 2 RepliesYesterday I asked why a adding 10 times 0.10 to a double is not equal to int 1;in VB Why (1 = 1) is False.I got an excellent answer. The overview is because:Floating point types and integer types cannot be compared directly, as their binary representations are different.The result of adding 0.1 ten times as a floating point type may well be a value that is close to 1, but not exactly.I can see the reason why now. However, if I do something like:[code]In this case I really obtain equality between double 1.0 and int 1. I thought then that double were only approximations so I would expect d to be somehow a value close to 1 as in the original first question. Why is not a good idea to compare directly different data types (in this case double - integer) and why I this time I obtain equality ??
View 2 RepliesI'm a little foggy on System.Type versus an actual class type (like Object or XmlDocument) in .NET... will this code correctly determine if the type of a particular object is equal to a class I specify?
// Given "myObject" (unknown type), and some class type (let's say "MyClass")...
If myObject.GetType.Equals(MyClass)
If TypeOf(myObject) Is MyClass[code].....
Which one is correct? Bonus points if you can provide some information on what a class identifier is versus what a System.Type is. :)
Note: The language doesn't matter here, VB.NET or C# is fine, the code above is pseudocode.

However this code sets up a link between the 2 variables, so when I clear stringa stringb is also cleared.
