I need to be able to generate short timezone names (like EST, CST etc.). The Timezone class gives me long names but not the short names. Is there any way to get the current short timezone name? I would have thought this would have been in the Timezone object.
Thanks

Hi, all.
I want to paste pictures that have been pasted in Excel.
When I "Copy & Paste" from other tools(MSpaint, MSPhotoEditor etc...),
the format in Clipbord is "Bitmap etc...". So, I can paste it by next code.
Bitmap bmp = (Bitmap)d.GetData(DataFormats.Bitmap)
But, from Excel, the format are "MetafilePict, GIF, PNG, etc... ".
Please help me how to convert(cast) these formats into "Bitmap".

i am planning to develop a rule-based ad & popup/-under blocking program as my degree level project. I am planning to use C#. I thinking of having the program as a standalone application that work in the background to screen incoming web pages for ads (by looking for keywords like '/ads' etc), remove the ad displaying codes, then feed it to the browser. the goal here is to prevent ads from being downloaded, so i must intercept the incoming pages before the browser gets to display it. i have no prior knowlege in doing this kind of program. note that the development has not started yet. i am asking this question because i forsee the problems. i have quite a bit of experience in programming.
My problem is: how do i intercept the page, removing the code lines, and then pass it to browser programatically. I am having a technical problem, so i really hope someone can shed some light and lead me to a technical solution.
My program should also distingush the popup/under opened explicitly by the user and the real culprits - the ads. one idea i got from a friend is to scan window's title bar for specific words (like 'great deals' etc) but i know that's not the best way. so again, i hope someone can give me more ideas on how to implement this.
Thanks in advance for all your help.

That one is a recurrent topic on Cp.
There are two kinds of ad-blockers :
- dictionnary based. They simply enumerate all visible windows on a regular time basis, and then they send a WM_CLOSE message to all windows which happen to have a caption matching an entry in a dictionary of known banned windows. There are two cons about this approach : - you don't prevent ads from being downloaded - the dictionnary needs to be (manually) maintained as there are many many many possible combinations of ad captions while you surf the web. At this point, may be a regexp (buit-in in .NET) can help and avoid the mere listing of banned captions. That's what proxomitron[^] does.
A trivial C# implementation is available here[^].
- the other approach watches URLs as they being requested from web servers. There are several approaches here :
-- hookup Internet Explorer navigation events, especially OnBeforeNavigate2, OnNewWindow2 and OnDocumentComplete.
-- redirect web requests to a proxy filter. This implies the user is required to change his IE settings, which is not that great (euphemism). Your proxy filter listens for connections on a dedicated port, then forwards everything back and forth to the actual web server. In between, he can filter out all html code from ad banners (pattern matching, regexp again). Watch my web condom[^]. 
-- and finally, you can write a .vxd driver, to monitor all incoming/outgoing requests without requiring users to change anything in their settings. Download the MS DDK. That's hardcore, now you are warned! 
In the second approach, depending on how perfectionist you are, you may need an html parser and even a javascript parser, even though from my personal experience I would recommend to stick with regexp and a few exprimental rules (that's were popup unders and stuff like that can be described with simple rules).

S.Rod,
Thanks for the reply. I'll try to look into the samples u pointed me to. But I am a student, and I am new to this area of developing this kind of program, can u please kindly point me to some other references.. like books i should read etc. i am not familiar with IE hookups as well. can u provide me with more info?
i might not consider the proxy / vxd options to filter the ads...
writing the ad blocker means going into an uncharted territorry for me. i am starting from zero & i need some good pointers and detailed references. your reply marked the start.
thank you.

That makes me wonder if Squid (linux) has a mod like this, especially being able to run as an transparent proxy, no user intervention would be required, except setting the default gateway, great for network use, bad for dialups, but who cares? I run a network anyways.

To implement the proxy module in my ad blocker (using C#), I am planning to do something like this:
- capture the browser's http request (get the URL string)
- redirect the request to the internet using Httpwebrequest class and receive the response using httpwebresponse class.
Initial testing worked, but it'll fail for sites with session control using session ids / cookies. I wonder if there's a remedy to this problem... also say when the user wans to attach a file (upload) in yahoomail, how can i handle that?
I am looking into the msdn library and docs for more info on the 2 classes i mentioned.
Please help.

When I made a web grabber a few years ago, I solved the cookie/session issue by recording web navigation first, produce an xml file, then manually change the xml file so it could be used as a replay scenario.
All this is described in a series of 5 articles there[^]. It's written in French!
PS : sometimes, the interesting point when you are trying to corner issues is to find yourself the solution. If you are only asking for someone else's help, then programming is useless, and provides no joy. Think twice!

Hi all,
I've made a Setup Project by VS.Net and I want to set it an Icon to show
in 'Add-RemovePrograms'. So I found a property named
'AddRemoveProgramsIcon' in project and set the icon to it.
But after I install the Setup just a windows Folder icon will apear in
'Add-RemovePrograms'.
My OS is Win 2000 Advanced Server. But when I tested it by WinXP the
icon apeared in 'Add-RemovePrograms' correctly.
Can anyone help me please?

There is a weird problem with Windows Installer on Win 2K which makes the icon not appear correctly if the Installation is per-user.
Microsoft's work-around is to make the installation per-machine (ALLUSERS=1), but that's not always a perfect solution. It's a trade-off, you have to decide how important your icon is compared to per-user installation.
I was lucky, we actually needed per-machine installs in the end anyway.

ILDASM  Come on be hardcore. On a serious note, Anakrino has not implemented all the op codes hence the crashing. I think S.Rod. had a look at the source, but it was incomplete, I guess we shall never get a new version...

The author says on his site that he hasnt had problems with 1.1, but apparently a lot of people have encountered this crash

Their demo version is almost unusable  It allows you to upload .NET exes or dlls to their web site and you get the decompiled output on your browser (that too, with restrictions)

The first comment on the site:
Small Point about .NET 1.1
(as of January 21st, 6:15AM CST)
Note that, as far as I'm concerned, Anakrino Interim #9 supports .NET 1.1. For those of you who claim it doesn't, I only somewhat believe you  . I _accept_ that it might be crashing for you, but I don't think .NET 1.1 is to blame. (I have .NET 1.1, and it works fine for me.) God, I want a better web page...

Ok. I get JUST the basics of c# n ado.net... Aw need some hep...
I gotta dumb little checkbook table, a datagrid and a dataset.
I get the connection, dataset and adapter Fill/Update stuff.
But I wanna:
1) hide the ugly key column
2) be able to update ideally without the dang uniqueidentifier column.
(don't need to insert or delete)
So far I've used the dang adapter wizard.
I hate the clutter it makes tho.
What all do I need to build my own SqlDataAdapter thingy?
Do I have to use a SqlCommandBuilder thingy?
And how do I hide the stupid uniqueidentifier column or lose it altogether?
Thanks for any help ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Make the column .Visible=false?
Steve Hazel wrote:

I make all my DataAdapters in-line now. Think along these lines...
using (SqlDataAdapter sqlDa = new SqlDataAdapter("SELECT foo FROM MyTable", sqlConn))
{
sqlDa.Fill(myDataSet.myTable);
using (SqlCommandBuilder sqlCb = new SqlCommandBuilder(sqlDa))
sqlDa.Update(myDataSet.myTable);
}Steve Hazel wrote:

Not if you want to build the update commands manually, but as you can see above, it's not that complicated.
The CommandBuilder sets itself up as a listener for .Update commands on the given DataAdapter. Then (as its name suggests) it builds the essential commands for the updates you want to do.

Hi,
I would like to do something like ICQ, where by, whenever a message is received, the window will flash to get the user's attention whether it is focused or not...
Does anybody have any idea how to do this?

Hi, all,
I am very close to finish my first .NET application( C#, Winform Datagrid, and MS Access database). I can modify all the data in my DataSet on my winform datagrid. NowI am trying for the first time to save the data back to my Access DB. When I call daMyDataAdaptor.Update( for a single table), I got this attached error. It says the UPDATE statement has syntax error, but the Statement was created by the wizard when I configured DataAdaptor, how can it be wrong? I know this must be something I missed, Please help.
Due to size limitation of the attachment, I can not attach the small test program. If you can help me, I can sent you the zip test program.
Code on Save button as follows:
------------------------------------
if ( connMain.State != ConnectionState.Open )
{
connMain.Open();
}
System.Data.OleDb.OleDbTransaction trans = connMain.BeginTransaction();
daTaskList.UpdateCommand.Transaction = trans;
try
{
daTaskList.Update(dsMain1, "LMTaskList");
//System.Exception MyErr = new System.Exception("Error Occurred");
//throw(MyErr);
trans.Commit();
}
catch(System.Exception err)
{
trans.Rollback();
MessageBox.Show("Failed to save Available Tasks!\n" + "Details: " + err.ToString() );
}
finally
{
connMain.Close();
}
-----------------------------------------------------
I wonder what is wrong with the code I have.
Thanks again.
Dion
