difference between isnothing and string.isnullorwhitespace
can anyone explain me the difference between between isnothing and string.isnullorwhitespace
hi [@rrenu59](/u/rrenu59)

form my knowledge

isnothing - method used to check if the variable is initalized, nothing means the variable is not intialized (i.e) there is no memory is allocated for this variable

nullorwhitespace - it is to check whether it is empty or contain any whitespace.
Check if any of the values in the cells are null.  

If they are you need to modify your code to check for null conditions before using `ToString()`. All whitespace: `/\s/g`  

All non-alphanumerics: `/[^a-zA-Z0-9]/g` I'm pretty sure that's platform-specific. winIds are HWNDs on Windows, so you could call `FindWindow(NULL, "Untitled - Notepad")` in the example you gave. not [full disclosure] a linux person per se.

something similar to the following should work:

https://www.unix.com/shell-programming-and-scripting/68166-converting-integer-string.html

start simple with just enough code to test the concept.

see if it works and modify/correct as necessary.

then if it still does not work, then post your documented code accordingly along an explanation of what is or is not happening as you expect or desire. Hi Qiunnn,
it´s confusing, I know :-(
Try to think of it like this
Kein - you use it when you talk about things. "Deine Frau isst keinen Käse, kein Stück" Cheese has a mass, is something
nicht - you use it when you talk about feelings or actions. "Du sprichst nicht" " Du schläfst nicht (action)" aber "Du machst kein Auge zu (an eye is a thing)". In both sentences you say that you can´t sleep but in different ways.
No rule is perfect but with this little memory hook you say it most of the time right.

PS. there´s one more "little" thing. Like I said no rule is perfekt.
When you use a noun than it´s unfortunately different. Nouns like trouble fear ect.
for example
Ich will niemanden ärgern/verärgern (action) BUT Ich will keinen Ärger machen.
Ich will dich nicht ängstigen (action) BUT Ich will Dir keine Angst machen.
or more difficult
Ich will dir nicht weh tun BUT Ich will Dir keinen Schmerz bereiten.
I hope, I didn´t confuse you even more^^ 版主! 您好!! (請您參考,如下資訊!謝謝!)

there's nothing in this world
there's not another girl that could satisfy my needs
there's nothing in this world
there's not another boy that could make me feel so sweet
cos me love life's so right
when she hold me so tight, how she kiss me goodnight
cos he fills up my life
like the sun, he shines bright
boy, come with me nowthe first night me meet her
yes me senorita me never want to leave her no
because the gal look sweet and ??
and me really want to take her home
cos she look nice and is a one of a kind
when me look up in her eyes then she got me mesmerised
picture perfect like a kodak moment
when she kiss me goodnight and she feelin' up on me
we been there from the jump, never front, never stunt
never done what a average girl done
and i can tell by her body language
she feels my emotions
and got me anxious
so that's me type
me and me angel
and me really have to let her know
she's the woman of my life
oh yes she so right
so please let the chorus go[chorus]

boy, come with me now for those who believe.......no proof is necessary. for those who don't..........no proof i ever enough. simple answer. no two nodes ever store the same data. instead storj uses erasure coding for which each piece is unique. so piece id’s are unique across the network.

maybe if a piece is lost and then subsequently rebuilt in a repair action it ends up having the same name on the new node. it would de… You can set the format of the fields to "None". How you do this will depend on a number of factors: since you haven't tried to explain in any detail, I'll assume you know nothing, and just give you the basics.  

  

The easiest way to do this is to read the text file into a single string, and then use the .NET framework to find the match:  


```
Dim text As String = File.ReadAllText("D:\Temp\MyFile.txt")
Dim index As Integer = text.IndexOf("hello")
If index >= 0 Then
   ' String is in file, starting at character "index"
End If
```
  

There are other ways, but that is pretty much the simplest.
