The printable area of a document is entirely based on your implementation. If you only want a certain region to be printed, then only print that region in your event handler for the PrintDocument.PrintPage event.
If you're talking about margins, see the PageSettings.Margins property.

Thank you.
But I want to get the Printable area before the PrintDocument.PrintPage event.

Again, this is entirely up to your implementation. There is nothing that sets a printable area in the printing classes in the .NET FCL. You should keep a variable that defines the printable area and set it through whatever means you like.

Hi,
I want to dynamically allocate datagrids depending on the input. So I declared a datagrid array .But it is not working . Can I do this way?
I tried keeping a single datagrid .It is working. Later I changed it into array keeping a loop.Now it is not working.

Hi,
I will take the number as input from the user and display as many datagrids as the number is.They don't have any values for present.( Later he can select the values to be present in each datagrid.)

Instead of using different DataGrids based on the input, use the DataGrid.TableStyles property to define different table styles with explicit DataGridColumnStyles. That's what it's there for. See the documentation for the DataGrid.TableStyles property for more information and an example.

The question isn't how do I split it into binary chunks which are unplayable but rather, "How do I split it into multiple playable .avi files?"
What I'm actually trying to accomplish is to cut a section out of an avi and have a shortened version which is playable.
I also need this process to be fast. The avi's are in RLE format and their audio is PCM (if that helps).
I also do not need 3rd party applications to do this it must be done within my app (even if I have to kluge a commandline to do it for me).
Also, importantly, I need to be able to tell it from what point to what point to cut out...though that seems obvious to me.
Thanks in advance for your help, you all are excellent!

Hehe, I searched for everything BUT AVI.
split avi
cut avi
edit avi
just not avi. I figured I'd just get a bunch of "how to show an avi on your form" type results  '
Thanks!

Hmm, not that helpful to me. Though admitedly I am a sad little C# newb 
HOWEVER, I used one of my valuable "Get the answer from a Microsoft dev" points and was given a C++ sample which does EVERYTHING and more that I need and quickly.
The code (and much more) can be found on MS MSDN Here.
You have to download about 130 or so meg of a huge file and then look search inside the file for "AVIedit."
I hope this is helpful to some of you. I have the extracted source which zipped is only 36k so email me if you would rather not download the massive file.

You mean an article that tells you what APIs to P/Invoke in order to split an AVI into frames when you want to split an AVI into frames isn't helpful? Hmm, interesting.

Can anyone tell me if there is a difference between "String" vs "string" in C#?
"string" comes up as a keyword in VS.NET.
"String" does not.
Just wondering.
Thanks.

They are identical (aliases). So are Object and object as well as Decimal and decimal and a few others.

hi all.
In my program I need to convert a double number to string representation in fraction format and vise versa. For example, convert 0.75 to string "3/4" and convert string "1/2" to 0.5. The class will only need to handle numbers that increment by 1/32. That is 1/32, 2/32, 3/32.... 31/32, 1. If the double number is 0.28 which is between 1/4 and 9/32, the string should be 9/32(go with the bigger number).
TIA

See the example source code for my article, Custom String Formatting for .NET[^], which includes a Rational class (a pretty common implementation). That should do what you need and then some.

Hi,
Can i get the value of current source column that failed to transform to the destination column in an OnError Event of a DTS package? I want to insert this failed value to a table for data maintenance.
Thanks for the help.

Thx for your reply. Sorry for the lack of information. I'm using C# to build windows application to execute a dts package and i set an event handler for the OnError Event. So, when the error occurs i want to take the value of source field that failed to be transformed.

There is no information passed to the OnError event handler that would give you any such information. You should look at the documentation for the OnError event in the DTS Programming Reference either in the SQL Server docs or in MSDN Library[^].
My only other thought is to examine several of the string parameters to see if any additional error information is returned that you could parse, but judging by what the documentation says it seems unlikely.
