Okay, I solved the problem.
Could be like this:
dim op as dropdownlist = ctype(repeater.item(i).findcontrol( _
"dropdownlistid"), dropdownlist)
op.selectedindex = 1

Hello
Could some of you, great people, please help me?
I have a array of controls and I would like to get the events.
Here is the code:
Dim pic(10) as system.windows.forms.picturebox
For a=0 to 10
pic(a)=new system.windows.forms.picturebox
' the rest of the properties
me.panel1.controls.add(pic(a))
next
How can I catch the events of the 'pic' controls?
Thanks

You have to write up the events of the PictureBox controls yourself using AddHandler[^].
Dim myPicBox As New PictureBox
AddHandler myPicBox.Click, AddressOf PicBoxClick
.
.
.
Private Sub PicBoxClick(ByVal sender As Object, ByVal e As System.EventArgs)
...
End Sub
Don't forget to use RemoveHandler to disconnect the handler before you destroy the picturebox.

You have used an array for the picture boxes which I don't suggest you to do that because you must have Addhandler or Eventhandler statements to control the event's of picture boxes.
According to your code, you should have one mutual eventhandler procedure which will run all the picture boxes. Focus on Addhandler and Eventhandler statements to get more information.
Here is an example from MSDN :
Sub TestEvents()
Dim Obj As New Class1
' Associate an event handler with an event.
AddHandler Obj.Ev_Event, AddressOf EventHandler
' Call the method to raise the event.
Obj.CauseSomeEvent()
' Stop handling events.
RemoveHandler Obj.Ev_Event, AddressOf EventHandler
' This event will not be handled.
Obj.CauseSomeEvent()
End Sub
Sub EventHandler()
' Handle the event.
MsgBox("EventHandler caught event.")
End Sub
Public Class Class1
' Declare an event.
Public Event Ev_Event()
Sub CauseSomeEvent()
' Raise an event.
RaiseEvent Ev_Event()
End Sub
End Class
)

Thanks
It worked fine!!!!

This would have nothing to do with a Help file being launched.
You're saying that VBA Help is launching along with YOUR help file? Is this code in an Office application?

I have built an application that watches a specified folder for any new/changes/deleted files. The program that keeps alist of all changes/added files in a listbox so that it knows what to move when instructed to. The reason this program was built to help my company transfer all changed files from our stage enviroment to our production enviroment for our website.
The entire program seems work, however when a file is copied, it seems to copy the "file.txt" but erases the data inside the original, as well as the new copy of it. Also the program checks to see if the "COPY" already exists, if so it makes a copy-of-the-copy, and puts that in a backup folder. It seems as thought when this process occurs, the data contained in that "COPY" is moved succesfully to the "BACKUP" folder, but the original "COPY" is then erased. showing "0kb". This is a big issues since I really dont' want this program deleteing all of our data when it try to move the files.
If someone can figure out why when I try to copy a file it erases the data, I would be very, very grateful.!!!  I plan on posting this application working one in articles within the next few days.

Without spending much time on this...
This is just a guess but ..
Dim fs As FileStream = File.Create(path)
fs.Close()
Won't this create a blank file? You create the stream and close it without writing any data.

So what is your solution, I mean I have tried moving this to the very end of my code (right after the "END TRY") and still nothing.
Please help, been struggling with this for 2 days now.

I figured it out. I didn't even need the "FILE STREAM" code in there, I removed it completely, and the fs.close() and it works GREAT NOW!. Look for a post to the articles section soon with whole program.

Hello!
I realized that the hide function of tabcontrol is not hidding the specific tabpage. Is there a way to enable/disable or hide/show a tabpage of tabcontrol instead of adding or removing it?
I am using VS 2005 and hide function is not working out with tabpages as shown below statement.
Tabcontrol1.tabpage(2).hide() <-- It is not hiding the tabpage
Thanks!

Hi
Is there any method that can be used to return form to state where it was created for the first time( clear all the text box, rebinding all the control, etc ) without closing the form itself?
Thanks and regards,
WiL
|
|
|
|
|
No, there isn't. You have to write the code to reset all of this yourself.
Your only other option is to kill the current instance of the form and create a new one.

in vb.net form, i have 1 text box and 1 command button
when user type in file name (no extension, just name) in the text box and click the button, it will open the file in a specific program (ex: winamp or wmp)
-click event:<br />
run winamp (or wmp) and play file with full path as "c:\data\ + file name (from text box) + .mp3"
help, please....
thanks a lot!

This will be a solution, if you make your application for you.
Name of the textbox is TextBox1
System.Diagnostics.Process.Start("c:\data\" & TextBox1.text & ".mp3")
You can use it, if Winamp is associated with mp3 files.
If not,
Right click on a mp3 file
Select open with.
Select Winamp from the list
Check Always use the selected program to open this kind of file
Click OK.
