Thanks for your quick response. I have come acrosss the Chilkat mailMan, what I need is how I can achieve this without a third party license class. Can I get a free dll or class that can do that. What I really what is how to implement something like MS Outlook using Vb.net.

MS Outlook uses a database to store all mail items. You will have to research how to store a mail item to a database.
My advice is free, and you may get what you paid for.

hi all,
i have a doubt about the DST. I want to ask whether DST is related to State or Country?
Please guide me or provide some helpful link

It is related to neither. It is an independent setting.

i need a most simple code to upzip a folder in vb.net

Not enough to google for it, apparently.
J# can do it, so if you're happy to write code that uses a J# dll, you can do that. Otherwise, you need to buy a third party component to do it.

let us say, we have winzip and winrar installed in the machine.
How are we going to use them to unzip the folders?

We aren't. We are going to use SharpZibLib SharpZibLib

You can do that, using command line arguments, but that would suck. Why did you ask this instead of reading what I told you ?

THNX in advance for the help.

To receive data is actually pretty easy...
1) Set your listview's "AllowDrop" property to true, to let it receive data
2) In the DragEnter event... In there, you want to check the data being dragged to make sure it's what you want, and if so, set the AllowedEffects property of the DragEventArgs it gives you. This is to let windows know whether to allow the drop to occur.
3) In the DragDrop event... Read the data supplied in the DragEventArgs, and process it.
The actual data being passed will be in a few different formats, so set a breakpoint and take a look at the formats to see how you want to receive it.

I have a background worker that executes a long running database extraction. Just recently, i have been asked to add a feature to cancel the operation. My issue with this is that the extraction is not done in a single query. My worker executes a query then waits a specified amount of time (30 seconds to 24 hours) and then executes a second query. The first query extracts data from the (current time - a user specified length of time) to current time and writes it to a file. the second query extracts data from the current time to the (current time + a user specified length of time) and writes it to a file. the wait in the middle is the accomplished with an AutoResetEvent and timespan. The below shows some pseudo code for the DoWork and RunWorkerCompleted events
DoWork
...update a status data table that the process has started
...execute query from this point in time and up to 24 hours earlier
...wait(time span, false)
...execute second query
RunWorkerCompleted
if e.Error
status = "Failed
if e.Cancelled
status - "Stopped By User"
else:status - "Completed"
....update the status data table that the process has completed
How do I go about cancelling this background worker. I have tried cancelAsync but because the process could be in the waitone section, I wouldnt be able to check the cancellation pending property until after the wait has finished, which could be hours. Is there a way to cancel a reset event?
Thanks for any advice

Instead of doing one big wait operation, put it in a loop...
timeout = DateTime.Now.Add(timespan)
Do While DateTime.Now < timeout AndAlso Not e.Cancelled
Loop
If e.Cancelled Then
.....

Hi Ian,
thanks for responding... i didnt even think of a loop (probably because its too simple). One other question then if you dont mind, because my background worker does its tasks in a few steps, should I check the cancellation pending before doing each one
check cancellation
do first query
do wait ...while checking cancellation
check cancellation
do second query

Generally, yes, but it depends on what you're doing, and on how long you expect each operation to take. It's a matter of balancing it between extra code/complexity and more responsiveness.

The data extraction will be the most costly time wise but even then I dont expect them to take an extraordinarily long time. I guess i will have to do some testing and see the best options. Thanks again for the advice

Hi,
I have a strange issue which I can't seem to find an answer to. I'm using VB.net 2003. I've created a form which containes textboxes. When entering data into a textbox, it is being displayed in reverse. This seems to happen when I place the cursor at the begining of data that is already in the textbox or when I start typing into a NULL textbox.
I have other forms which work just fine. This one was working great until this morning. I'm sure that I can't be the first person to run into this issue but I can't seem to find an answer anywhere.
Thanks in advance,
Nick

When your cursor is at the beginning of the text box, are you clicking the mouse button to reset the cursor to the beginning of the text box?
You do know clicking your mouse in a text box will move the cursor.. right?

Hi,
May be that the "Home" key of your keyboard have drinked some drop of coffee or whisky?

OK...thanks for the NON-answers.
"You do know clicking your mouse in a text box will move the cursor.. right?"
"May be that your "Home" key on the keyboard have drinked some drop of coffee or whisky?"
Lovely responses...NOT!
I figured it out. I was using the "TextChanged" property when I should have been using the "Leave" property. "TextChanged" kept placing the cursor at the begining of the field on every keystroke.

I am not exactly sure why you are jumping on everyone else, and using that kind of attitude. You provided no code, and a pretty weak explanation of the problem.
It is a little hard to give a sound response when you don't supply the correct information. Next time you post, try to help everyone out a little bit, and supply some real information. Otherwise, you will get answers that don't help.

I'm not jumping on anyone else and I could have lived with answers that didn't help. At least they would have been answers.
If I knew which part of the code was causing the issue, I would have included it. At the very least, that's the answer that I should have received. Silence would have been far more intelligent than the smart ass remarks that I did receive.

No, it did not. Your code moved it. The event does nothing.
You jumped on every one here for making wise ass comments, but the fact is, if you have a control doing something weird, you should start by looking at any code that involves that control, especially events. Just commenting out your code would have told you which part had the issue, by a method of elimination. When people post questions with no code at all, the most you can hope for is guesses, and those guesses will probably follow the same process of elimination that causes tech support to ask things like 'is the computer plugged in'.

When answering a question please:
1.Read the question carefully
2.Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
3.If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
4.If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.

Do you remember this? The above is one reason that I joined this message board. I started coding back when assembler was the in language. Because of the above, I thought that I'd get honest and possibly thoughtful responses to my questions on VB regardless of how rediculous they may have seemed. I guess I was wrong. Obviously, you don't take much stock in what you've written. Please remove me from this site. I'd rather spend my afternoons searching Google for the answers that I need.
