. You can't improve much on this, and not at all in managed code.
CPU usage is another thing, which u can access through managed code(c#). Try looking into System.Diagnostics namespace especially PerformanceCounter class and related.
there are no facts, only interpretations

If you are using Sql Server 2005 you can use DateDiff[^]

Put the Value of Date in DateTime Variable
Then U can easily deduct date value
Like
Dim var_date as datetime
Var_date = "2/13/2008"
var_Date = Var_Date.days - 3

hi all,
I am a beginner in C#. I want to Send and receive files through parallel port. Since i am working in Windows 2000 Professional, I used Inpout32.dll for parallel port access. I used 0x378(data register)(888) for sending and 0x379(status register) for receiving. I can send data as 1 byte . But on receiving side, data received is different.
Eg: If i send 1 , i will get ---- as 136
for 2, i wil get 144.
for 15 - i wil get 0.
Does anyone can help........?
Thanks

Hi,
Some of the status inputs are inverted...
Here is a link showing which ones are.
http://www.doc.ic.ac.uk/~ih/doc/par/[^]
Also... there only appears to be 5 inputs... so how can you receive 8 bits (1byte).

Thanks Matthew.....
then, how would i get the data?
i wan to get the data i sent. On sending, we send as 8bits.(1 byte).
How can we receive tat data using 5 bits?
any idea...?
Please help yar..........
Once again Thanks..................

If your are using a DB-25 port then...
According to Wikipedia... (Quote)
<br />
Monodirectional parallel ports<br />
In early parallel ports the data lines were monodirectional (data out only) so it was not easily possible to feed data in to the computer. However, a workaround was possible by using 4 of the 5 status lines. A circuit could be constructed to split each 8-bit byte into two 4-bit nibbles which were fed in sequentially through the status lines. Each pair of nibbles was then re-combined into an 8-bit byte.<br />
The general idea with parallel ports is that you only send 'Data' in one direction (away from the computer) and only send back status bits.
When you receive data it shouldn't go 'into' a parallel port, it should be read (all 8 bits) onto the controller (microcontroller etc) port.
When sending data back, 4 bits of the controller's port should be connected to four of the status bits (see wiki page) and then the fifth status bit could be used to say which nibble (half-byte) is being sent.
To summarise...
The computer (the master) has 8 bits output, and 4 (or 5) bits input.
The device (the slave) will have as many pins as needed (8 bits receive, 4 (or 5) bits send).
You need to send data from the slave to the master in two (half-byte) sections.
[Also: Is there any particular reason why you are using parallel ports? (Serial is really simple to use)]
Hope this helps.

Thank u dear...
as u said, serial is better. But i used to transfer data between an instument and Computer via parallel port(Since interface provided by the instrument is Parallel Port (db 25 pin connector), i have to use this port for data transfer)...
Once again,
thank u for ur reply

How do I find a memory leak in C#, I have several hundred datatables I load data to. On shutting these datatables down I do not reclaim all the memory it used while loading, I probably loose about 50% of my memory.
Thanks in advance,
Michael

Hi,
I declare various objects to be available in a form immediately in the class declaration eg
public partial class MainForm : Form
{
int totalCourts;
int totalViewPeriods;
int totalBookingPeriods;
int minimumBookingPeriods;
etc...
What I want to do is declare objects conditionally ie if a variable = say 9 then make an object available. Specifically I want to make tableadapters made at design time to be available at runtime.
Is there some way to make these available in the Form Load event?

Your best bet is to make the object available via a property which can throw an exception or return null if you don't want it to be available.

Hello
It seems really impossible to programaticaly assign values to a binded datagridview. In the following example I'm trying to renum a column value
The result is unpredictible : some values are assigned, some not ?
Some are reflected to the binded dataset but not all ?
private void Rit_Renum()
{
int Step;
int Order = 1;
int.TryParse(txb_renum.Text, out Step);
if (Step < 0) Step = 1;
dgv_rit.Columns["order1"].SortMode = DataGridViewColumnSortMode.NotSortable;
Order = 1;
for (int i = 0; i < dgv_rit.Rows.Count; i++)
{
if (dgv_rit.Rows[i].Cells["order"].Value == null) break;
dgv_rit.Rows[i].Cells["order1"].Value = Order;
Order += Step;
}
dgv_rit.Refresh();
}
I start with a sorted list 1 to 12
I swap a few contiguous rows values
(11 = 12, 12=11) then sort
(10=11, 11=10) then sort
(9=10, 10=9) then sort
So now the original row 12 have the value 9 and the position of 9
Then I renum with a step of 3
The result is this ??
1
3
4
6
7
9
10
12
16
22
28
34
Does anyone undersdand what happen !

Generally, databound controls tend to blow up if you try to change or add to them. You should change your datasource to change the values.

Thank you
Indeed !
That was my conclusion !
But why does it works for manual entry ?
|

How do you mean ? Why does it work when the control is not bound ? Because it's not refreshing itself to a datasource. Why does it work sometimes ? I suspect because you don't know when it will rebind. All I know for sure is that it's safer not to do what you're doing.
