You should specify the exact scenario. Which database you are using (SQL Server, Access etc.)

Doesn't that explain?
Your MS Access file is ReadOnly. You can not write a read only file.

Hi,
I'm getting serial ports names with the following code:
System.IO.Ports.SerialPort.GetPortNames();
It gives COM1 and COM3, but the problem is, COM3 doesn't exist under "DeviceManager -> Ports".
(After restart)
Any suggestions?

Do you have an internal WinModem? These sometimes create a virtual COM port which will not be shown in the Device Manager. Take a look at the modem-properties in the configuration-screen.

Yes, you are right.
I have hdaudio data fax modem, its port is com3, and some ports are in use (com5, com6)
But com3 is not in use.
When I pluged usb-serial adaptor in notebook, com3 is appearing under "Ports". After, I can use this port.
If modem is using or reserved (but com3 not in use) the port, how did adaptor take this port?
So, How can I get correct port list (without com3)?
Thanks...

You can give System.Management a try, I have used it before to enumerate hardware. I don't know for sure whether virtual com-ports are included, and I can't test it on my own machine (at least not without installing a new com-port). You'd need to add a reference to the assembly "System.Management" to use this functionality. The code would be something like this;
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("SELECT Name FROM Win32_SerialPort");
foreach (ManagementObject mo in searcher.Get())
Console.WriteLine(mo.GetPropertyValue("Name"));
Console.ReadKey();Alternatively, you could scan the registry. Open RegEdit and search for the friendly name of the COM-port

hi friends,
could you please let me know how do I get the index of checkedlistbox If I pass itemtext(string)?
thanks,
Jeet

loop through the items and compare the text value - select the item and bail out of the loop.
If you are binding use the same field for the DisplayMember and the ValueMember

Hi All,
I want to do a process on specific tab. So I do similar to this.
private void AllTabs_SelectedIndexChanged(object sender, System.EventArgs e)<br />
{<br />
if(AllTabs.SelectedTab == tabMyTab)<br />
MessageBox.Show("FOUND");<br />
}
On click the specific tab, message is pop-up. But the issue is, message also pop-up on the form load as well. I don't want to do that. Can someone help me to sort out this.
Thanks a lot
I appreciate your help all the time...

Create a form level bool
bLoading = true;
In your selected indexchange event do the following as you first line of code
if(bloading)
{return;}
the last thing in the form load method set bLoading to false

Hi,
You can remove the Events from the AllTabs while loading and add back it again.
To remove an event.
AllTabs.SelectedIndexChanged -= new ...........

Hi all,

please help......

htParameters.Add("dtOvdDate", string.Format("'{0}'",dtOvdDate.ToString("dd-MMM-yyyy")));
htParameters.Add("dtOvdDatePrev", string.Format("'{0}'",dtOvdDatePrev.ToString("dd-MMM-yyyy")));
htParameters.Add("strAndPaid", string.Format("'{0}'",strAndPaid));

This is in the nature of the hashtable. all elements are sorted by the hash of the key as mention here:
http://msdn.microsoft.com/en-us/library/system.collections.hashtable.aspx[^]
"Represents a collection of key/value pairs that are organized based on the hash code of the key."
Use List< KeyValuePair< T,T > > for that unless you need an efficient by-key retrieval
And please post code that compiles for others, like keep consistent field names (what is parameters?) and post code that works without rewriting all of your format variables.

I can give the rectangle of a control by bounds.but I don't know how get the visble rectangle when a control not display whole.
Rectangle r = ctrl.Bounds;
ctrl.DisplayRectangle;

What do you mean by not displayed whole?
Windows keeps track of what parts of a control need to be repainted and joins them together into a 'clip rectangle' which is passed the the OnPaint handler.

Thanks!
I have two container controls like follow "a" and "b"
┌────┐
｜ ｜
｜ a ｜
｜ ｜
└────┘
┌───────┐
｜ ｜
｜ b ｜
｜ ｜
└───────┘
b is bigger than a
And I drag b into a,so b only display the visible area and I want to get that,not b.bounds
┌────┐
｜ a┌──┤
｜ ｜ ｜
｜ ｜ b ｜
└─┴──┘
how can I get it?
|
|
|
|
|
Ok,I get it,follow
ctrlP = ctrl.Parent;
Rectangle r = ctrl.Bounds;
Rectangle rP = new Rectangle(0, 0, ctrlP.Width, ctrlP.Height);
r.Intersect(rP);
but I have new issue,I want to draw the border of the "display bound"
Graphics g = ctrlP.CreateGraphics();
Pen p = new Pen(Color.Red);
p.Width = 1.5f;
g.DrawRectangle(p, r);
g.Dispose();
It draw the top and the left line fine,but the right and the bottom line were clear,because OnPaint event of ctrl?
and this method was fired in Form_Paint(object sender, PaintEventArgs e).
|
|

|

Yup, that looks good using the intersection of the two rectangles. The right and bottom line are probably not appearing because they're outside the clip rectangle. The Rectangle method draws a rectangle where the dimensions you supply are the area inside and not including the lines.
Try deflate()ing the rectangle a bit and you should see all four sides.

Rob Philpott.
