There are a few different methods TaskManager TRIES on the Applications tab before doing the brute force "halt execution and free the memory" method. This last-ditch method is what the Processes tab uses when it "kills" a process. It isn't detectable by your code since your process ceases to execute when TaskManager obliterates the Process using this method.

No, there isn't. You code STOPS executing, immediately. You don't have any way of detecting this if your no longer running.

Does anyone know how to delete a line within a txt file. I am trying to clean up a file that has unnecessary lines.
Any advice would help!

You need to read the file into memory, remove the lines, and overwrite the file. You can't just delete a line from a file.

Do you have any sample code?
|
|
|
|

File.ReadAllText and File.WriteAllText ( from memory ) will let you read and write an entire file. The System.IO.File class has static methods to do it, for sure. And, the My shortcut in VB offers this stuff as well My.FileSystem, I think.

But is there a way to get rid of a line in the file through code?
|
|
|
|
|
No. There is a way to read a file, and a way to overwrite a file. There is no way to select a line in a file and delete it. You need to read in the whole file, manipulate it, and over write it. as I said.

I have created a window service which accesses a folder on a seperate system and writes a file into it.
Everyone has been granted access on that folder
Now when i install service with user account it is able to create file into it,
but when i install service with either local system,local service or network service it is anot able to write file into it. it says "Access denied" to that folder.
Is there a way that i can write file into that folder with either local system,local service or network service.
Since i have tried with all possible right granted to that folder.

"everyone" does not include IUSR/IWAM/ASP.NET
try giving asp.net user write access to that folder (if it still fails try iusr/iwam also)
|
|
|
|
|
I have a window service which is accessing a shared folder on another server.
how does ASP.Net user will solve this problem as it is for IIS.
Also i want to access folder by installing services with "Local System" status
|
|
|
|
|
My apologies...I misread window service as webservice. you can use impersionation. have the window service logon as someone that does have access or falls under the group everyone when writing to the shared folder...

I have impersonated using WMI,
and while checking directory i use
system.io.Directory.Exists("Shared folder path")
it gives me exception "Access Denied" cause when i register service as Local System it uses Local system a/c to get access to the folder and that's why it says "Access Denied"
but when i Register it with User account it uses that a/c to get access which is in Everyone.
The work around is that register the service with User a/c but how to access folder with service registered "Local system"

sorry i explained the query wrong. i need to use a button to replace the selected item with the one above, and do the same with the one below. i suppose this code could be modified a bit but dont know how. can anyone help me please.
Select Previous:
ListBox1().SelectionMode = SelectionMode.One
If Me.ListBox1.SelectedIndex > 0 Then
Me.ListBox1.SelectedIndex = Me.ListBox1.SelectedIndex - 1
End If
Select Next:
ListBox1().SelectionMode = SelectionMode.One
If Me.ListBox1.SelectedIndex < Me.ListBox1.Items.Count - 1 Then

oh i think i understand, you want the selected item on button press to have the same value as the next or previous item.
If that is the case:
Make sure your listbox selectionmode = selectionmode.multiextended
Select all:
ListBox1().SelectionMode = SelectionMode.MultiExtended<br />
For i As Integer = 0 To Me.ListBox1.Items.Count - 1<br />
Me.ListBox1.SetSelected(i, True)<br />
Next
Change current to same as previous:
ListBox1().SelectionMode = SelectionMode.One<br />
Dim Selected As Integer = Me.ListBox1.SelectedIndex<br />
Dim newItem As String<br />
<br />
If Me.ListBox1.SelectedIndex > 0 Then<br />
newItem = Me.ListBox1.Items.Item(Selected - 1)<br />
Me.ListBox1.Items.RemoveAt(Selected)<br />
Me.ListBox1.Items.Insert(Selected, newItem)<br />
Me.ListBox1.SelectedIndex = Selected<br />
End If
Change current to same as next:
ListBox1().SelectionMode = SelectionMode.One<br />
Dim Selected As Integer = Me.ListBox1.SelectedIndex<br />
Dim newItem As String<br />
<br />
If Me.ListBox1.SelectedIndex < Me.ListBox1.Items.Count - 1 Then<br />
newItem = Me.ListBox1.Items.Item(Selected + 1)<br />
Me.ListBox1.Items.RemoveAt(Selected)<br />
Me.ListBox1.Items.Insert(Selected, newItem)<br />
Me.ListBox1.SelectedIndex = Selected<br />
End If

I want to be able to click only on the childs and not the roots in a treeview. Is this possible and if it is can somebody please explain to me how to do it. Thank You!
|
|

If you click only on child nodes how will you ever be able to use the expand/collapse feature of treeviews? This is one of the advantages of using a treeview.
Not saying it's impossible, just think it's a bit weird. What exactly are you trying to do? Maybe I can help.

I have a datagridview in which I have a list of items some of which are priced in Dollars and some in sterling is there any way to format the columns accordingly.
I have a second column which can be used to pick the currency up from eg.
Roller skates 22.40 USD
Fishing Rod 34 GBP
what I would like to see is
Roller skates $22.40 USD
Fishing Rod £34.00 GBP
I can format the Whole column if they are the same currency using
.CellTemplate.Style.Format = "C2"
I assume this picks up the default currency? If I can alter the currency Symbol for an individual cell then I'm Ok.
Thanks for any help

Hi
I'm populating an xml file from a dataset. There are some columns that sometimes don't have a value. The problem is that those column names don't appear in the xml file when they don't have a value. How do I get those columns to still appear in the xml file and not be ignored?
Thanks,
