hi,
i would like to know how i can communicate from e.g. windows shortcuts or context menu items in windows to my program ...
i think i will have a installer finally creating these and adding some registry values and they should e.g give me the location where e.g. the windows explorer is active atm ... ?
something like a context menu extension...
dont know where start searching ...
thanks a lot!
cheers phil

that the code i wrote
FileStream w = new FileStream("d:\\HufmanCompression.txt",FileMode.Create);
BinaryWriter writer = new BinaryWriter(w);
for (i = 0; i < array.Length;i++ )
writer.Write(array[i]);
w.Close();
The output i need is to write a binary file with a very small size(it is a compression prog)
thanx for ur time

And the problem is...?

I don't seem to see a question in your message? What's your problem exactly? Your code is one way of doing it. What's wrong with it?
Ps.
Make sure to call writer.Flush() at the end of your code before slocing the stream.
Regards

Doesn't Close flush the stream?
|
|

Well, in his case Close() will flush the FileStream, but not the BinaryWriter. So I suggested that he'd call writer.Flush() to flush the BinaryWriter too.
Regards
|
|

|

But he's closing the writer. That flushes the writer, closes the writer, flushes the stream and closes the stream.

b { font-weight: normal; }
|

|
|

IIRC he called
w.Close();
and w is the FileStream. How does that close the BinaryWriter -named in his code writer-?
Regards
|
|
|
|

Yes, you are right in that. I didn't read the code thorougly enough, and was confused by the naming of the variables and what the code really should have been doing. He closes the stream when he should really close the writer instead.
The best way is of course to close the writer, not the stream:
writer.Close();
If you close the stream, you can solve the problem with the buffering in the writer by flushing the writer first, but it still leaves the writer in a confused and unusable state when the stream is closed.

Hi
I want to get sql server table fields Description, I want to use them for my datagrids header text.
So how can i get field description from database table?
Tanks

What makes you think there ought to be one? Take a look at DataColumn class in your documentation, you'll see it has no description member. I usually name my columns in the database in a human friendly way so that I'd name the DataGridColumns with the same string using a loop -with some modifications of course like removing underscores-.

Just because the DataColumn class doesn't have such a property doesn't mean there is now way to get this info...

And what other ways do you know to get that information? Also when you make a Sql table where do you put that information?

I wasn't asking for an answer. I was proving my point of view that there is no description for Sql columns. If Robert knew how to get it he would have posted the answer. BTW where did you put that description anyway?!!
freshonlineMax wrote: I had a code to fetch database informations, but i lose it in my harddisk.
Database information?? You mean that present in the INFORMATION_SCHEMA? Check the INFORMATION_SCHEMA.COLUMNS table and see if it has a description field!!

Hello Again
Dear friend 'Nader Elshehabi'
I solve my problem my self!
Now i can help myself, you(if agree) and others (if it's useful!)
Just run below query in sqlServer:
SELECT objtype, objname, name, value
FROM ::fn_listextendedproperty(NULL, 'user', 'dbo', 'table', 'YourTablename', 'column', DEFAULT) AS fn_listextendedproperty_1
If we want to get special column's description, we should type column's name instead of 'DEFAULT'. Field 'value' refers to column's description.
Regards

Hi,
maybe this[^] is a good start.

you can retrieve data from SQL select :
select b.name,c.value from syscolumns b, sysobjects A,sysproperties c where a.name ='bed' and a.id=b.id and b.id=c.id and b.colorder=c.smallid
then use this rows to modify your datagridview column tex
if you can design this, i may design class for you:
SetDatagridColumnTextBySqlDescribe(DatagridView dview)
Think ...

Hi all,
Can anyone tell me how do we create minidumps for crashes and hangs in windows applications c#.net 2.0.
I have used ThreadException handler and AppDomain.CurrentDomain.UnhandledException handler to catch exception and log the information.
But what can be done in case of a crash or hang in application.
Can i use ADPlus for this, if so how to implement it??????..........
Thanks,
Pranu.

If your program crashes you won't be able to use it to dump its own memory now, would you?
Anyway, if you implement exception catching well in your program, it shouldn't crash or hang -specially in a managed environment like .Net where you can't screw up with pointers-, it's unhandled exceptions that makes your program crash, and windows Xp or later provides an automatic memory dump for your application. Most user won't know how to extract the data from the report and send it to you, but if Hex dump is one of your favourite languages you can simulate the scenario and read it as you please -not convenient as you can see-.
