There is your problem

but when i deployed at client location its gets entered as dd-MM-yyyy format

When displaying a date (and inserting it into db in a varchar column) without specific formating it will display the way the date settings are set in Windows.

First of all you should use a date column type.

Then you can either instruct your client on how to change his OS settings (not recommended)
or do a format of the date.

If you had said that in the first place it would have been obvious, its a localisation issue nothing to do with sql. Use a proper datatype and your problem will be solved.

Hi,
i have a excel document saved with temp.xls name.
i wanted to open this xls file as a new xls doucment,

Your question is very hard to understand. You want to have a file called temp.xls, but don't want to open it as such? Create a copy of it and open it. If you don't want it to be overwritten, make it read-only.

tnanks for reply, actuly i saved an excel file into temp folder,
and if we open this file and then close it from upper left corner 'X'(close) button then excel document do not ask to save
the file, untill i don't do any modification in file.
so what i want, if i launch temp
file and then user try to close the file then document should ask
the user to save the file, if user want to save the file then it should ask for the filepath where he want to save, instead of using temp file path, beacuse i am using it for temprary purpose.

Is it possible to get result set from a Oracle store procedure via ODBC?

17-Jun-09 17:33

Hi guys,

I got a Oracle store procedure which would return dataset using a ref cursor,it's quite easy to get the result set if I use the classes in System.Data.OracleClient because there's a type OracleType.Cursor which matches the procedure parameter's type.

But is it possible to do this via ODBC? There isn't a type likes 'OdbcType.Cursor'.

Anything you can help it would be appreciated. Smile | :)

Creating a new excel workbook with C#

Hi,

I need to work with Excel via C#, but I'm having problems getting started. Keeping it simple to start, I'd just like to open a new Excel workbook.

MSDN describes using code like this:

objExcel = new Excel.Application();
objBooks = (Excel.Workbooks)m_objExcel.Workbooks;
objBook = (Excel._Workbook)(m_objBooks.Add(m_objOpt));

Yet Excel is not recognized by the compiler, which I'm assuming is because I haven't exposed the right namespace.

I'm not sure what that would be. Intellisense is not offering Excel as an option anywhere I've looked. Elsewhere I've heard about using ADO.NET, but haven't seen anything I can get to work.

If anyone has worked with Excel via C# I'd appreciate any guidance...

Thanks,
Jeff

you have to use the name space :
using Microsoft.Office.Interop.Excel;

And this helps to open the excel:
Microsoft.Office.Interop.Excel.Application m_objExcel;
Microsoft.Office.Interop.Excel.Workbooks m_objBooks;
Microsoft.Office.Interop.Excel._Workbook m_objBook;
Microsoft.Office.Interop.Excel.Sheets m_objSheets;
Microsoft.Office.Interop.Excel._Worksheet m_objSheet;
Microsoft.Office.Interop.Excel._Worksheet m_objSheetIntro;
Microsoft.Office.Interop.Excel.Range m_objRange;
object m_objOpt = System.Reflection.Missing.Value;
m_objExcel = new Microsoft.Office.Interop.Excel.Application();
m_objBooks = (Microsoft.Office.Interop.Excel.Workbooks)m_objExcel.Workbooks;

m_objBooks.Open("Your excel file path here", m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt);

Hi,
Thanks for your reply. For some reason my compiler is not recognizing the Office part of the namespace.

If I use Intellisense after Microsoft it gives me [Contracts, Csharp, Internal, SqlServer, VisualBasic and Win32.] Not Office.

I'm using C# Express. Could that be the problem. Maybe I need a higher level version?

no, just you have to add references..
1) rightclick your solution file.
2)click add reference.
3)add the reference file.

Hi,

Again, thanks for your replies.
It's a minor miracle, but at least the system is recognizing the namespace. I'm not sure what has changed since numerous times I tried different combinations of Excel Object refs and Office Object Library refs (earlier/later versions).Nothing seemed to work.

I tried one last time by deleting as many refs as possible and referencing only Excel 11.0 Objects. Suddenly it worked. I'm saving this as-is and will experiment later to see if I can replicate the bug.

Thanks,
Jeff

Re: Found Office

Jeffrey Webster17-Jun-09 19:28

17-Jun-09 19:28

Hi,
Okay, I added two references: Office 12.0 and Excel 11.0.

So now the compiler recognizes *Office* but claims never to have seen *Interop*

The article called *Excel Interop Use in C#* by Sam Allen amazingly doesn't mention where you would find these references.

I'm seeing the solution you've described crop up on the net but I'm really not seeing how to wake up the compiler and get it to smell the namespaces.
