thanks but how to kill explore.exe?

Don't listen to him. You do NOT want to kill Explorer.exe.

It's a situation that, if you have to ask, you shouldn't be told. Because the way to replace explorer can also make a system nearly unusable. Which means by the time you know how to deal with not having explorer, you'll also find out how to replace it.
Until then, start reading up on the windows resource kits. They'll let you enable security policies that can do what you're looking for in a safe manner.

I would like to have the functionality to: on click, edit a subitem in a Listview.
I am building an MP3 file ID3 Tag editor and am loading a listview with all the tracks found in a folder. I would like the ability to select a particular entries subitem, then edit it. I know the first column can be edited, but have been unable to work out how to do this for subitems. I know I can get the text from the subitem, or even replace the text in a subitem, but I'd rather have it behave just like it does when the first item in the row is selected for editing. (This makes sense?)
The CodeProject site has something like this, and I think it places a textbox over the selected cell for editing purposes - however it is coded in C# and as a noob, I do not know how to convert this to VB code. D'oh!
Any advice would be gratefully accepted.
I am using Visual Studio 2008 if that helps.
All the best,
Ross

There are plenty of C# to VB translation programs out on the InterWeb. Have a Google and play with one or two.

Hi all,
I want to select a folder from FolderBrowserDialog and write into a textbox and append all the files within the folder shown in the textbox as one file in the same folder...
Code sofar:
Private Sub BtnFolder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFolder.Click
Dim MyFolderBrowser As New System.Windows.Forms.FolderBrowserDialog
MyFolderBrowser.Description = "Select the Folder"
MyFolderBrowser.ShowNewFolderButton = False
Dim dlgResult As DialogResult = MyFolderBrowser.ShowDialog()
If dlgResult = Windows.Forms.DialogResult.OK Then
Textbox1.Text = MyFolderBrowser.SelectedPath
End If
End Sub
The above code opens a FolderBrowserDialog and allows to select a folder and the selected path is copied to the textbox.
Now, i want to know how to append all the files within the selected folder and write as one new textfile by clicking a button.
Thanks
Vijay

Three things.
1 The Button1_Click should be
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
AppendFiles()
End Sub
You need to tell it that Button1_Click_1 handles the Click event.
2 This is a hodge-podge of VB.Net and VBScript. You don't need all that FSO stuff. Have a look at reading and writing textfiles on MSDN or help system.
3 Be careful with the folder path. It needs to end with '\' before you join the filename, but that's not what is in the textbox.
Having said that the basic idea seems sound, it just won't work. It's relying on e.g. MainFile being a variant which does not exist in VB.NET. (Look at the two assignments: ones a string the other a file object.)
It won't even compile if you have Option Explicit and Option Strict set (as they ought to be).

The line AppendFiles(TextBox1.Text, "c:\DB\append\Append.txt") just passes the folder into the sub not the files in the folder.
You also need to loop through the files in the folder. Something like this:
Dim theDir As DirectoryInfo = new DirectoryInfo(iFile);
Dim datFiles As FileInfo() = theDir.GetFiles("*.txt");
Using sw As StreamWriter = New StreamWriter(oFile, True, System.Text.Encoding.Default)
For Each (fi As FileInfo In datFiles)
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read and write text
End Using
Next
End Using
Syntax might not be quite right - copied and edited from C# code - but the general idea is ok. 
This is what your friend's Do...Loop was trying to do.

Im getting 2 errors in this line
For Each ( fi As FileInfo In datFiles)
1)fi not declared
2)')' expected
I declared fi as string but still there is an error.
|
|
|
|
|
Should be For Each fi As FileInfo in datFiles i.e. no ( or ).
That's what happens when you copy and paste from C# which requires ( and )

Thanks a lot I have written the code for Read and write and its working fine now.
I need to write the file creation date for the appended files.
Code I wrote:
GetCreationTime(iFile)
The creation time for each time is different, but its writing the same date for all the files...
Is there anyother method that could help to write the file creation date and time???
|
|
|
|
|
This would get creation time for file
For Each fi As FileInfo In datFiles
Dim created As DateTime = fi.CreationTime
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read and write text
End Using
Next
I don't know where you're calling GetCreationTime() but it looks like you are passing in the folder and not the files.

Thanks a lot, that works fine.
Im using CreationTime() while writing the file.

Does this mean that there may not be a header in a file? Or should it be When the header is found?
In the first case (i.e. IF) then you have no guarantee that the first file read will contain a header so you need to do something like this.
Dim theDir As DirectoryInfo = new DirectoryInfo(iFile);
Dim datFiles As FileInfo() = theDir.GetFiles("*.txt");
Using sw As StreamWriter = New StreamWriter(oFile, True, System.Text.Encoding.Default)
'Write the header lines to output file
For Each fi As FileInfo In datFiles
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read line from input
If 'header line' Then
'Skip it
Else
'write to output
End If
End Using
Next
End Using
You can write the header either by reading a special header.txt file that only contains header lines (and is not in the folder you're searching) or by hard coding the text as strings. The first way is better because if the headers change you don't need to change the code just the txt file.
If it's the second case (i.e. all files have header, you could do something like this.
Dim theDir As DirectoryInfo = new DirectoryInfo(iFile);
Dim datFiles As FileInfo() = theDir.GetFiles("*.txt");
Using sw As StreamWriter = New StreamWriter(oFile, True, System.Text.Encoding.Default)
Dim skipHeader as Boolean = False
For Each fi As FileInfo In datFiles
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read input line
If 'header line' And Not skipHeader Then
'write output line - first line of header
'read input line - second line of header
'write output line
skipHeader = True
Else
'write output line
End If
End Using
Next
End Using
Note that this assumes there's only one or two header lines.
Note also that this is pseudocode mixed with VB not pure VB.
There's two problems with this
vijay2482 wrote: if name.contains("Nom du Modéle") or if name.contains("----") then
else
'read and write
End If
1 You don't need the second if.
2 When you find a header you still need to do a read, the best way is to do the read then the test for header as in the two bits I've done.

Look at what WriteHeader() does and where it originally came from. You're not doing the same thing here.
In this code you have not done a read of the first file so there's nothing to write.
I think some of the problems come from you trying to hack one program (i.e. the one that did parent and child for a single file) into another one that concatenates files while stripping out header lines in all but the first file. The logic of the two programs is different and you need to think about it before coding.

Here's a better solution for when all files have headers.
Dim theDir As DirectoryInfo = new DirectoryInfo(iFile);
Dim datFiles As FileInfo() = theDir.GetFiles("*.txt");
Using sw As StreamWriter = New StreamWriter(oFile, True, System.Text.Encoding.Default)
'Read and write first file including headers
Dim fi As FileInfo = datFiles(0)
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read input line
'write output line
End Using
' Read and write subsequent files excluding headers
For i As Integer = 1 To datFiles.Length()-1
fi = datFiles(i)
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read input line
If 'header line' Then
' skip header line - do nothing
Else
'write output line
End If
End Using
Next i
End Using
Much neater and gets rid of awful skipHeaders flag.

How is it possible to do a read befor declaring the streamreader???
Using sw As StreamWriter = New StreamWriter(oFile, True, System.Text.Encoding.Default)
'Read and write first file including headers
Dim fi As FileInfo = datFiles(0)
Using sa As StreamReader = New StreamReader(fi.FullName, System.Text.Encoding.Default)
'read input line
'write output line
End Using
|
|
|
|
|
'Read and write first file including headers
is a comment - if you read the code you'll see that it does declare sa at the appropriate place.
The comments in the using blocks do need to be replaced by code.

Here's an annotated version of your code.
You need to think about the logic of the code rather than just hacking.
Roughly it is something like this NOTE this is not VB it's just looks a bit like VB:
Fill the pf array
Using streamreader for first file
read and write two header lines
Loop while data lines
read and write data line
End Loop
End Using 'Closes streamreader
For second and subsequent files in folder
Using streamreader for first file
Loop while input lines
read input line
If header line Then
'do nothing
else
'write data line
End If
End Loop
End Using 'Closes streamreader
Next
Unless you get the logic clear you'll keep stumbling around wondering why things don't work or give the output you expect.
