I want to load a button in taskbar,
Such that I can give some options to user for selecting.
For example, if there is the button of open office 2.1 Quickstarter, and if I rightclick it, there comes some options like Text Document, spreadsheet, Presentation, Drawing, database etc.,
In the same way, If I right click the button which is loaded through my program, therre should come some options for user to select.
How to do these in c#?
A callback was made on a garbage collec delegate of type 'CrystalDecisions.ReportAppServer.DataSetConversion!CrystalDecisions.ReportAppServer.DataSetConversion.DataSetConverter+CrdbAdoPlusDelegate::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.

// Now recurse down the directories
DirectoryInfo[] dirs = dirInfo.GetDirectories();
foreach (DirectoryInfo dir in dirs)
{
deleteOldFiles(dir.FullName, olderThanDate);
}
}
So, what's your question? If you want to change your program so that it deletes folders which are n hours old, instead of n days old, then you change deleteOldFiles(path, DateTime.Now.AddDays(-DaysOld)); to deleteOldFiles(path, DateTime.Now.AddHours(-DaysOld));
And please, put your code in <pre> tags. It makes it much easier to read

I need help from u all. I'm using combobox control in my program. My problem is if i select the items more than once from combobox it should display an error message.
Hi All,
I have Class library with name and namespace Dipak.DataAccess and within this name space there is class called DataAccess.
I have another class library with name and namespace Dipak.ESchool.Data and within this namespace there is class called StudentData. Now i have added reference of Dipak.DataAccess in Dipak.ESchool.Data and i have added using Dipak.DataAccess statement in StudentData class .
While calling method of Dipak.DataAccess i have to use full name like DataAccess.DataAccess.GetDataSet(),after adding using Dipak.DataAccess statement.
And when i changes namespace from Dipak.ESchool.Data to ESchool.Data i need not to give full name for method call i am able call with classname.methodname, no need to add namespace name.
Can any one explain me why it is so?
And what i need to do for correcting above problem.
<br />
namespace Dipak.DataAccess<br />
{<br />
publicclass DataAccess;<br />
{<br />
}<br />
//-------------------------------------------------<br />using Dipak.DataAccess<br />
using Dipak.ESchool.Common;<br />
<br />
namespace Dipak.ESchool.Data<br />
{<br />
publicclass StudentData<<br />
{<br />
DataAccess.DataAccess.GetDataSet()<br />
//i want this call to be like DataAccess.GetDataSet()<br />
}<br />
}<br />
you have to use the fullname DataAccess.DataAccess.GetDataSet because the compiler doesn't know if you write only one DataAcces what you mean: namespace or class.
I suggest not to use the same name for a class and a namespace. That can cause too much trouble as you see.

Sebastian
P.S.: What about naming the DataAccess-namespace "DataAccessLayer"?
Thanks for your reply...
I tried using ur solution...it works...
But as far as concept is concerned ....i have included using statement as using Dipak.DataAccess....so at this point compiler will be knowing the clearly that this name space is referenced...what matters if same class name is there in namespace...
what matters if same class name is there in namespace...
What matters is that the M$ coders didn't provide for this scenario. FWIW I agree with you, but the fact remains that we have to work with the tools we have.
If this is the first of VSs little annoyances that you have encountered, then you are a lucky, lucky chap.

thanks buddy..
but as i have mentioned in my problem description that if i changes my namesapce from Dipak.ESchool.Data to only ESchool.Data it works fine.
But with Dipak.ESchool.Data i have to make call like DataAccess.DataAccess.GetDataSet().
As per naming standerds for namespace we follows Compnyname.projectname.namespacename and thats what i have done...
Dipak my compny name....DataAccess and ESchool my Project name ....

I want to know the better way of filtering Bulk data, pls guide me...
I have two flat files with lakhs of rows having 16 digit numbers.
i want to filter the numbers from first file with second file , resulting in a unique identified numbers.
I am doing it like this.
I am inserting these data into two seperate tables using bulk insert in Mysql.
And then from my web interface iam inputing two flat files, whenever user clicks on filter button
iam querying tables with a select statement using NOT IN sql statement, but it is taking lot of time and even resuling in a connection timeout.
If the table has key column, I suggest following steps.
1. Insert key value, to be filtered, into temporary table.
2. Query with "NOT EXISTS" like "select .. from table where not exists ( select ... temporary_table where table.key = temporary_table.key )"
