Take a look at this[^]. One of the responses claims to do the trick. Unfortunately the code is C#, but have a look, you may be able to convert it yourself, but if not I'm sure that someone here will be able to help you out.
I have also found this snippet:
SendMessage(treeView.Handle, WM_HSCROLL, SB_LEFT, 0);
This also uses the Windows API, I don't think it is possible without doing that, but there's plenty on the web about the SendMessage API call, you will also need to look up the values for the WM_HSCROLL and SB_LEFT constants.
Good luck!

This guy has posted the same request in more than one forum.
I have asked him to remove one, and explained the reasons that he should.
He appears not to want to.

Several things wrong with your post:
0: this is the VB.NET forum, your question is about webdevelopment so go to the ASP.NET forum : Correct forum[^] and ask there again
1: every question here is urgent, the people answering however don't get payed so you'll get an answer whenever you get it.
2: from what I can understand from your question, what you are trying to do isn't possible (as far as I know), but ask in the correct forum and people can make better suggestions

If it succeeds, no exception will be thrown, and File.Exists(destination) will return true

When handling text files and doing actions on them I always find its best to read the whole text file line by line into a datatable or array or list. Do your actions you need to do on that datatable / array / list and then overwrite the file with a new one.

From memory :
dim dt as new datatable("a name")
dt.columns.add(new datacolumn("column1",getttype(string)))
dt.columns.add(new datacolumn("column2",getttype(string)))
dt.columns.add(new datacolumn("column3",getttype(string)))
dt.columns.add(new datacolumn("column4",getttype(string)))
...
'now that you have your datatable
'read your textfile line by line
do while not reader.eof
dim dr as datarow = dt.newrow
dr.item("column1")= "your value for that column here"
dr.item("column2")= "your value for that column here"
dr.item("column3")= "your value for that column here"
dr.item("column4")= "your value for that column here"
...
dt.rows.add(dr)
loop
'now you have your entire textfile in a datatable
'you can do all your actions on that datatable now and then overwrite your textfile with a new one
hope this helps

what tool should i add from the toolbox to use this code???
is it a DataGridView or DataSet or something else.....
i feel like sitting in a dessert where there is nothing available...
my mind is completely blank.....

If you don't want to display the file on a form you don't need a tool
This
dim dt as new datatable("tablename")
create's the datatable
This
dt.columns.add(new datacolumn("column1",gettype(string)))
Create's a column within that datatable with the name 'column1' and datatype 'string'
this
dim dr as datarow = dt.newrow
create's a new row in the datatable
this
dr.item("column1")= "value goes here"
puts 'value goes here' into this new row in the column 'column1'
so you do the code I send you urlier
while reading your textfile (you already have that code) you fill the datatable.
Every line in your textfile is a new row (dim dr as datarow = dt.newrow) in your datatable.
Every "column" in your textfile is a column in your datatable
Once you have done this you can easily go over the datatable and add / delete / alter rows
for each dr as datarow in dt.rows
if (some check)=true then
'do something here
...
else
'do something else here
...
end if
next
and as last action just run over your datatable again and for every row you write a line to your textfile

That's where its going wrong. Readtoend returns a string. When doing a check with 'not' in it you need to have a boolean type.
For reading the text file you have to use the code you already had. (nothing changes there) but instead of trying to do your alterations (delete/new/alter) inside that loop you just put your data (from the textfile) in the correct column in the datatable.
Then after you'v read the text file, you can do all your alterations on the datatable.
(A datatable is basicly the same as a table in sql or access)

You already wrote the code to read your text file and split every line in several parts (columns). You posted that a few post below.
Use that code but instead off altering your text you add the specific text to the correct column in the datatable.
After that you can start with doing your checks / alterations.
You have all the code you need to do this in front off you, you just need to put it together.
