hi all .net programmers. I need logic.
I can download one file at a time
sending command PASV and RETR
but it downloads only one file at a time
if file is retriving.. I can send more command except ABOR (server don't response)
is there any way to download multiplefile in same time.. (JUST like in Cute FTP Professional 6.0)

You can do multithreading. You can retrieve different files on different threads. However, you need to design your application to support multithreading - think of thread locking issues, UI update issues, how to share data between threads etc. - MSDN would be a good place to start.
In short, multi threading is the answer to your question.

I think the question might be related more to desktop applications and hence div tag may not be applicable.
[edit]Seems like the post I replied to was deleted.[/edit]
For the OP - You can generate a class object from the data in the gridview and generate a report based on that class object.

Okay i was wondering how i could change the name in the list box on an amend feature.
so far i got
<br />
<br />
Dim Rum As Integer<br />
<br />
If listbox1.SelectedIndex = -1 Then<br />
Exit Sub<br />
End If<br />
<br />
Num = listbox1.SelectedIndex<br />
<br />
frm1.R.Rt = txtRtText<br />
frm1.R.Rp = CSng(txtrp.Text)<br />
<br />
<br />
frm1.Rooms(Rum) = frm1.Room<br />
<br />
txtRt.Clear()<br />
txtRp.Clear()<br />
It changes it in "rt" and "rp" but wont change the name in the list box

What form is this ListBox on and what form is this code you posted on? Are you trying to update a listbox on one form from another? What is frm1 and how did it get defined?

Basically it is all on the same form but i a "Class" with
"RT" = String for a name
"RP" = Integer for a number
So basically i want to be able to recall data into textbox ( i know how to do this) then amend the current data.
If i select "Coffee" from the listbox it will display " coffee " and the "number" in two different text boxes. The amend on the Number works fine but when i change "Coffee" to "Coffee with sugar", it will still display "Coffee" in the list box. So now if i click "coffee" again it will show " coffee with sugar" but still coffee as the list box item and i want it to be "coffee with sugar"
Only way i found around it is by making it delete it from there and readding it but surly there is a way around that ,.
<br />
<br />
Dim Rum As Integer <br />
<br />
If listbox1.SelectedIndex = -1 Then 'if list box = not selected then ..<br />
Exit Sub<br />
End If<br />
<br />
Num = listbox1.SelectedIndex ' making variable = list boxes selected index<br />
<br />
frm1.R.Rt = txtRtText ' makes the class R.Rt = textbox<br />
frm1.R.Rp = CSng(txtrp.Text) ' makes class r.rp = textbox<br />
<br />
<br />
frm1.Rooms(Rum) = frm1.Room <br />
<br />
txtRt.Clear()<br />
txtRp.Clear()<br />

The code you're showing doesn't update the ListBox, so it's impossible to say what you're doing wrong. But, have you tried calling Refresh on the ListBox when you're done updating it?

How do you refresh the list box, the code i provided only updates the where the data is being store i thought it would refresh/update the name once u change it
|
|
|
|

Uhhh, no. You'll have to remove the item from the ListBox and re-add it.
Your other alternative is to create a typed dataset, load your data into that, then bind the ListBox to the dataset. If you do that, then any changes to you make should be updated in the ListBox when they're made.

hi,
i wrote following code to validate my all controls on form.
it is working well but when i run my project & for testing purpose i leave the textbox as it is
following code executed & showing appropriate message but it is validating controls randomly....& i wnt that it should validate control in a sequence
( e.g. employeeid ,empname,designation......etc).
i have given tabindex to all controls in sequence though it is validating controls in random manner Wht shuld i do??
Is there anyone who will solve my problem????
Public Function Validate_Ctrl(ByVal sender As Form) As Boolean
For Each obj In sender.Controls
If TypeOf obj Is TextBox Then
If obj.Name = "txtSearch1" Or obj.Name = "txtSearch2" Or (TypeOf obj Is CheckBox) Then Continue For
If obj.Text = "" Then
MsgBox("Please Enter Values In " + obj.Name, MsgBoxStyle.Exclamation + MsgBoxStyle.OkOnly, obj.Name + " Validation")
obj.Focus()
Validate_Ctrl = False
Exit Function
End If
End If
Next
Validate_Ctrl = True
End Function

As far as I know, the for each loop will visit the controls not according to tab index, but something else.
A cumbersome method can be to load all the controls in an array and then sort them based on their tab index and then apply the validations on them.
A simpler method might be to use ErrorProvider and the validate events for a better control over validation (This applies only in .Net 2.0) - so if you are using VB 6, ignore this part.

Is this homework, or are you being paid to write this ? Sounds more like the former, but either way, the way to do this is well documented online, if you're not willing to do some research and start your project, you're on your own. If you're willing to give it a go, and ask specific questions when you get stuck, we're here to help.

What do you want to disable ? The odds are, the answer is 'computer says no'

The best way to do it is through Group Policy. Or, you can just edit the registry key that disables it. See here[^].
