What is a reciever ? What do you mean by image, a bitmap, or a serialised version ?

You can begin by making your question clear.

I can. Why did you ask this here, when it's an ASP.NET question ?

( you pass values on the URL to change how the page is shown by default )

Hi,

I developed a windows application in Vb.Net 2003.It is working fine in this.
But when I am trying to convert this into .Net 2005 I am getting this error.

I am seeing a lot of people reporting this error, on other forums, but no one has an answer
Please anyone help me how to resolve this problem.

What COM object are you using ? Is it registered ?

How to send an HTTP request with VB.Net while using the cookies already stored by Internet Explorer?

You could try hosting IE as a control, and try to get access to the cooke info from there perhaps ?

I am having a lot of trouble with this when I thought that it was supposed to be really easy. I have a form designated to specific settings in my program. Specifically I need to manipulate a tab control (I got that part down.) But I can't figure out how to do this on another form and have code work for the other. This is essential or I can't implement any optional settings. Please, I only have a week until this thing is due. Sniff | :^)

Why don't you give us the code you have and let us know where you are getting an error and what error you are getting. Generally, if you have Form1 and Form2 and Form1 has the tabcontrol, you should be able to put code similar to this on Form2 to manipulate Form1:

Form1.tcMyTabControl.SelectedTab = tpMyTabPage

Hope this helps.

I have a thread running in the background of Form1 and the thread permanently opens up a new form, Form2, by calling the ShowDialog() method of Form2. On form2 I have a SaveFileDialog but if it tries to open I get this error:

"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process."

What can I do to resolve this?

How do I best save a datatable to .csv format?

Thanks!

Depends on what databse you are using.

How so? I have a datatable in memory that I want to write to .csv. Can I use an adapter, or do I have to enumerate the rows and columns of the table, adding my own commas between each cell and writing the result as a text string?

Thanks!

This might be far fetched, but perhaps Independentsoft[^] would know something about it? Wink | ;)

Despite everything, the person most likely to be fooling you next is yourself.
