Hi,
What is wrong with the following:
Dim nodesArray() As String
Dim i As Integer = 0
For Each node As RadTreeNode In nodes
nodesArray(i) = node.Value
i = i + 1
Next
I'm trying to populate an array, but I keep on getting the following error:
Object reference not set to an instance of an object.
Please can some one help?
Regards

You have not initialized your array. Try
Dim nodesArray() As New String
|

C:\Inetpub\wwwroot\...\PowerSearch.aspx.vb(317): Arrays cannot be declared with 'New'.
Any other ideas??

VB.NET I don't know. C# you can instantiate array's like
string[] Arr = new string[10];
|
|
|

Instead of an array ( which is empty, because you've not called new on it ), try using a List of string. Or just call new on the array, so that it has the space to add the values you're adding.

HI!
when user press enter on a textbox, cursor move to next textbox. is it possible without using javascript?

Of course not. Why do people keep asking questions in this forum and saying 'without using javascript'. You have NO other options on the client side, unless you want to support IE only and use VBScript.

A gridview supports in place adding and editing of rows. Deleting is also easy to add. There are tons of tutorials on the web, there's no way I could explain it as well as an article could, in a forum reply.

hi,
I want to generate images on button click by using image paths present in listbox.
|
|

Do a postback, and generate your image using GDI+, just draw them based on the values in question. You can then use Response.BinaryWrite to send the image back down, or write it to the local file system and generate an img tag. Or you can just send it as a download.

The extra line to web.config i wrote would get you trough this part as then you will see the error occuring.

Where is that EXTRA LINE?
|

<configuration>
<system.web>
<customErrors mode="Off" />
</system.web>
</configuration>
The extra line is: <customErrors mode="Off" />

Sorry to say but still im getting the same error. I thought VWD2005 is not generating bin folder which according to my information is necessary.
Please Comment and help.
