If the return value is a long, then it's probably the date value in ticks. You can convert it to a DateTime object via: DateTime dt = new DateTime(LastModified(directory));

Thank you very much.
I have found the solution, but a bit different to your suggestions.
I have just tried your suggestion but it didn't work. The problem lies in the returned value LastModified from IndexReader of Lucene.Net, which is the number of millisenconds from 1970.01.01.

Hi,
In my application I have developed a visual component with a panel and some controls on it(buttons, picture-boxes etc.). I want to make some parts of the components invisible according to some needs.
So I am making those controls' Visible property false. The problem is I am using this component in several forms however when I build the project all controls' visible property becomes true again.
Component does not remember state of the visible property.
How can I solve the problem
thanks..

Add properties in the component for the visibility of the children you want to be able to hide. For properties to be remembered for a specific instance of a component, they have to be properties of the component, not properties of a child of the component, as the properties of the child is common for all instances of the component.

Hi
I wrote a small app that receives a string array with file names from windows explorer (using 'Send To').
If i send up to 28 file names every thing is ok. If I try to send 29 or more I get this error message:
"Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item"
And the app closes. It doesn't even enter the app or the try/catch should have caught it.
Any ideas please?
This is the startup class:
static class Program<br />
{<br />
[STAThread]<br />
static void Main(string[] args)<br />
{<br />
try<br />
{<br />
Application.EnableVisualStyles();<br />
Application.SetCompatibleTextRenderingDefault(false);<br />
Application.Run(new frmMain(args));<br />
}<br />
catch (Exception e)<br />
{<br />
MessageBox.Show(e.Message);<br />
}<br />
finally<br />
{<br />
Application.Exit();<br />
}<br />
<br />
}<br />
}

Only yesterday there was an item (I believe regarding "mailto:") with some buffer limited to some 2048 bytes; I guess you are hitting the same limit.

Hi, I have a DataTable with 4 columns (id, type, length and note) which i bind to a DataGridView (mydataGridView.DataSource = mydataset.Tables[0];). How can I make the "type" column in my datagridview a DataGridViewComboBoxColumn with 3 values (say "white", "black", "gray") representing the same values stored in the DataTable type column?
Any help would really be appreciated.

Load the XML file into an XmlDocument instance, select the nodes you want to change using its SelectNodes or SelectSingleNode methods and finally change the node value as wanted. The documentation of the mentioned class and methods contains many examples, so you should be able to figure out the coding yourself.

Hi!
I want to make an image filter in Visual Studio C# .The function of such filter is that redraw the original image only with its dark pixel.
I used following logic but its too slow and not efficient
for (int i = 0; i < 300; i++)
{
for (int j = 0; j < 200; j++)
{
p = new Pen(bitmap.GetPixel(i, j), 1);
for (int r1 = 0; r1 < 100; r1++)
{
for (int r2 =0; r2 < 100; r2++)
{
for (int r3 = 0; r3 < 100; r3++)
{
if (p.Color ! = Color.FromArgb(255, r1, r2, r3))
{
p.Color = Color.Transparent;
}
g.DrawRectangle(p, 1 * i, 1 * j, 1, 1);
}
}
}
My second question is that how we can manipulates the images in visual studio c# .net ,like convert the image in black &white color,grayscale etc etc
Please send the some code or hints+links

Hi,
take a look on the class ServiceController (include Reference System.ServiceProcess).
Sample:
ServiceController controller = new ServiceController(<servicename>);
controller.Refresh(); // Controller should read state
if (controller.State == ServiceControllerStatus.Running) // Service is running...
...
you will receive an exception if the specified service does not exist.
|
|
|
|
|
|
Dim service() As System.ServiceProcess.ServiceController
Dim i As Integer
service = System.ServiceProcess.ServiceController.GetServices()
For i = 0 To service.Length - 1
If service(i).ServiceName = "wampapache" Then
If service(i).Status = ServiceControllerStatus.Running Then
' Kill the Service
service(i).Stop()
Application.Exit()
Else
Dim startInfo As System.Diagnostics.ProcessStartInfo
Dim pStart As New System.Diagnostics.Process
startInfo = New System.Diagnostics.ProcessStartInfo("E:\Biswabhusan_Collection\COREPRACTICE\TestService\wamp5_1.6.1.exe")
pStart.StartInfo = startInfo
pStart.Start()
pStart.WaitForExit() 'Your code will halt until the exe file has executed.
End If
End If
Next

List<int> lst_int=new List<int>();
lst_int.Add(3);
lst_int.Add(5);
lst_int.Add(2);
lst_int.Sort();
MessageBox.Show(lst_int[0].ToString());
struct mystruct
{
int x;
int y;
}
How do I implement "sort" for lists of type mystruct?
List<mystruct>
List<mystruct> lst_mystruct=new List<struct>();
mystruct mys;
mys.x=10;
mys.y=12;
lst_mystruct.Add(mys);
how do I sort now?

Implement the IComparable and/or IComparable<mystruct> interface(s) in your struct.

Hi all,
I want to develop a textbox(more like richtextbox control) where users can enter some text, but the bitmaps are displayed instead of characters. The user should be able to edit the text and the corresponding values should be preserved(between the text entered and the corresponding bitmaps). How do i go about doing this. Is there a way to override the paint event of the textbox so that the bitmap is drawn instead of charcters.
Please help.
Thanks for reading.

The textbox is not written for overriding, as it paints itself outside of any paint event, getting it to custom draw is always nasty. I'd say it's almost better to start from scratch.
