Create a ProcessStartInfo object and configure it with the executable name, any command line parameters, etc. Then start the process using a Process object.
Dim si As New ProcessStartInfo
'COnfigure si properties to define process to run
Dim p As Process = Process.Start(si)

For starters ->
If ddlClothTapeColors.Visible = True Then - can't happen, you just set it to false
So, ddlBlindRemote will ALWAYS be visible.
I suspect that when something is invisible, it's not rendered, which means your view state is lost as well.

I think this [^] can help you. It's C# (basically the same).

my VB.net in Visual Studio .net 2003. it doesn't seem to recognise the registrykey command because it would put wavy blue lines under it..

Are there any ways to convert all the items in a listbox into one string?
E.G. A,B,C are items in a listbox. I need to create a string (A B C) according to the listbox.
|
|
|
|
|
Iterate through the item lists and concatenate the string.

Any chance of explaining that a bit further? I don't understand
|
|
|
|

Not sure, how to code it in VB. Try this.
String temp
temp=""
For Each item In ListBox1.Items
temp=temp+ item.Text
Next item
<italic>Work hard, Work effectively.
|
|
|
|

Dim tempString As String = String.Empty
Dim item As String
For Each item In ListBox1.Items
tempString &= item
Next
Or
Dim tempStrings As String() = Array.CreateInstance(GetType(String), ListBox1.Items.Count)
ListBox1.Items.CopyTo(tempStrings, 0)
Dim resultString As String = String.Join(", ", tempStrings)

Can anyone help me???
how to send file (eg powerpoint slide, flash, video etc) from server to client in .net remoting in vb.net.
Thank you!!!

Remoting is not the best method for sending files. A better choice would be something dedicated to the task, such as FTP, BITS, or your own custom written implementation.

I have a calendar that comes up over a combo box(which is how I want it), but the combo box shows through the middle of the calendar? Probably an easy fix I'm sure.

hi,
in control panel > internet connections > connections > lan settings > proxy
i can define what should go through proxy i choose, then i can write what will bypass it...
is there a way to define only one port/remote ip request that will go through the proxy and all other will bypass it ?
thx.
|
|
|
|
|
If I understand your question correctly, no, there isn't. The proxy settings in IE only work down to the IP address/hostname, not the port level.
