My MaintenanceLog table has an entry with following data in a row.
Name: Toney Mirra
ActualDateTime: 2007-02-16 12:55:02.867
PlannedDateTime: 2008-12-05 20:08:57.000
Comments: Sample Entry
But when I run the following query it doesnt return any value.
I think there is some problem in DateTime format. Can anyone help me fixing this?
select Comments from MaintenanceLog where
ActualDateTime = '2/16/2007 12:55:02 PM' and
PlannedDateTime = '12/5/2008 8:08:57 PM'

Well, in general you should use the ISO format because it is culture neutral. YYYY-dd-MMTHH:mm:ss.fff
Your query doesn't work because there is no data that maches. Your ActualDateTime is 867 milliseconds out from what is stored in the database.

www.componentone.com one of the components (C1Flash) can do that
VirtualVoid.NET
|
|
|
|
|
you can host a browser control on your form and then you should be able to load flash in that

hi Navneeth
Thanks for ur concern ,
here is my code
initailizing code:
Microsoft.Office.Interop.Excel.Application objExcel = new Microsoft.Office.Interop.Excel.Application();
code for Reading from excel:-
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
Workbook CallListWorkBook = objExcel.Workbooks.Open(openFileDialog1.FileName, 0, true, 5, "", "", true, XlPlatform.xlWindows, "\t", false, false, 0, true, 0, 0);
Sheets CallingSheet = CallListWorkBook.Worksheets;
Worksheet worksheet = (Worksheet)CallingSheet.get_Item(1);
Range CallingRange = worksheet.get_Range("A1", "A1");
CallingRange = CallingRange.get_End(XlDirection.xlToRight);
totalColumn = CallingRange.Column;
string downAddress = CallingRange.get_End(XlDirection.xlDown).get_Address(false, false, XlReferenceStyle.xlA1, Type.Missing, Type.Missing);
//string downAddress = CallingRange.get_Address(false, false, XlReferenceStyle.xlA1, Type.Missing, Type.Missing);
CallingRange = worksheet.get_Range("A1", downAddress);
System.Array CallingValues = (System.Array)CallingRange.Cells.Value2;
//objExcel.Workbooks.Close();
//objExcel.Quit();
ConvertToStringArray(CallingValues);
}
Code for writing in excel:
Excel.Workbooks CallListWorkBooks;
Excel.Sheets CallingSheet;
Excel._Worksheet worksheet;
Excel.Range CallingRange;
Excel.Workbook CallListWorkBook;
try
{
// Instantiate Excel and start a new workbook.

//Get the CallingRange where the starting cell has the address
//m_sStartingCell and its dimensions are m_iNumRows x m_iNumCols.
CallingRange = worksheet.get_Range("A1", Missing.Value);
int totalrows = arr.Count;
CallingRange = CallingRange.get_Resize(totalrows, 1);
//Create an array.
string[,] saRet = new string[totalrows, 1];
//Fill the array.
int j = 0;
for (long iRow = 0; iRow < totalrows; iRow++)

why C# interfaces doesn't contain data members?
|
|
|
|
|
Because it doesn't actually implement anything. It only provides a contract that states what methods/properties will be present.

Because that is not the purpose of an interface.
An interface defines the public interface* of a class (or part of a class) that implements the interface.
If you want data members then you should look at implementing an abstract class.
* Note there is a difference between interface and interface

Hello,
Does anyone know how to elevate Users in Vista progrmatically without any User Interface to appear?
I need to do this in order to install something, which normally can be installed only by an admin, from a lower user account...
Please help me if you can. I need urgent help..
Thanks
L.P.

I don't believe that this is possible, because it would represent a major security hole in Vista. One of the tenets of Vista is that elevation only happens when the user agrees to it. If it didn't then virus and trojan writers would be able to run rampant throughout Vista.

You can't. At the point that elevation occurs a dialog is presented on a secured desktop to which the user must be respond. The secure desktop means that processed also cannot hijack the window (by getting hold of its handle) and respond on the user's behalf.
Lucian.Palcu wrote: I need to do this in order to install something, which normally can be installed only by an admin, from a lower user account...
Then I would definitely say you need admin rights for that!
Interestingly Vista contains some funky virtualisation stuff which means that you cannot write to the Program Files directory except as admin. However, for compatibility with older or badly behaved programs if a write is detected it will create a special directory in the user's profile and write the file there to protect the integrity of the system.

hi,
i need lil help.i want to make a winform in which i have to make a grouppanel which looks the same like the toolbox in the microsoft visual studio.
i want to pick up labels from that panel n want to drop it in the same form.so i want that treeview thing to b the same as in that toolbox. i just want to add labels in that panel n nothing else.
n those labels should b dragable.
plz can anyone guide me with this problem. its very urgent n i got deadlines 4 it
thanks
reply soon.

The toolbox in Visual Studio is a custom owner-drawn control (based on TreeView I think). To create a control that looks and behaves the same is a non-trivial task. If you're more interested in the functionality and don't need it to look as slick as the VS toolbox, you can use a simple TreeView control.
As for drag and drop, it's pretty simple. Search CodeProject for articles on that topic -- there are several.

Hi Friends
How a size of a class can be determined? As an example
Class A
{
}
Class A
{
int i;
public A()
{
i=10;
}
}
Class B
{
A aa=new A()
public B()
{
}
}
What would be the size of object of type A and B ??
Thanks in advance. 
Thanks,
Arindam D Tewary

Unfortunately, there's no quick and easy way (unless you're using Mono where Marshal.SizeOf returns the size of a type in managed code). Common methods for working with size information include using GC.GetTotalMemory, but this is not fine grained enough for the type of detail you want.
A better alternative is to use the .NET profiling API. Unfortunately, this means that you are probably going to get down and dirty with C++.

Hi
The easy way is start your windows project as a console application.
To do this go to
Project\properties\Common properties\General
Change the value Output Type from Windows Application to Console Application.
Now run the project.
You will see that a console window will be opened fist which then launches the windows application what ever you write using Console.WriteLine will now appear on the Console window.
Please let me know if this helps
