You either have to know the object that you calling GetText on very, very well, or consult a Ouji board.
Other than that, the best way is to step through the code in the debugger and watch what happens to the variable contents.

Hello
I am new to VB.net and have a form where I am trying to update an Access database from a datagridview that I databound on the fly. However when I change something on the grid and press the update button it would seem that the dataset has accepted the changes, but when I next look at the grid, it hasn't updated. Can I use a SELECT statement in the way that I have?
Am I doing something wrong in the code, or is there something in the grid properties that I need to change?
Many thanks

Hello! 
I have a picturebox (width=60, Height=60) size mode is set to Strechimage. I am loading an image to picturebox which has bigger size and then I want to save this image back to hard disk with smaller size (size of picturebox)?
Can you show me how to do that please?
Thanks!

VB or VB.NET?

Use the GetThumbnainImage method of the Image class.

b { font-weight: normal; }

Hi,

thanks

the links are for C#. I am looking for VB.net
|
|
|
|
|
C# and VB.NET use the same .NET framework, so the first link still applies.
Also, the 2nd link he provided takes you to a C# to VB.NET code converter.

Questions like that usually spark religious war like debates. 
A search on the Internet and on this website will find many debates on this topic, having all kinds of strong opinions.
In my opinion, other than the syntax, there is little difference between C# and VB.NET. Both languages have nearly identical language featuers and they use the same .NET class framework. I would say that it is to your advantage to learn both languages and doing so would make you a better ".NET developer".

Use the second link to convert c# to vb.net code.
Good luck

This is a guess. You may need to add a COM reference. When I find something that really works I will post again.

If you're using .NET 2.0 (Visual Studio 2005) then you can use this...
My.Computer.Network.Ping

Web browser control's Navigate and Navigate2 methods look for either a file on a web server or a local file(htm) on the application root. Is there a possibility to use this by passing a html fragment( say <h2>Hello</h2>) to it?
Simple trial shows you get an Action Cancelled web page with no HTTP errors(possibly it's not http).

I found the easiest way was just to create a temp file and navigate to it then delete it.
Changing .DocumentText dosn't work except the first time you use it.

Thanks a lot. The html fragment is only in memory and not in a file. You wll have to call additional programs to commit it to a file before navigating to it. I am looking for a easy way out.
