Hello All!!
I have created a windows service and the problem is when I log off my system account in which the service is currently running, the service stops. Why is this so? I want my service to run independent of my system account.
Thanx in advance

Is it a real windows service?

System.Windows.Forms.ListView does not support that.
Try the article search for "editable list view".

Yes, it can contain more than one output parameter
maaran wrote: how can i get the output value
By asking each SqlParameter for its Value after the SqlCommand has been executed.

can you give one simple sample with two output parameter
|
|
|
|
|
Not complete, but it should give you enough to work with:
SqlParameter p1, p2;
p1 = new SqlParameter( ... );
p1.Direction = ParameterDirection.Output;
p2 = new SqlParameter( ... );
p2.Direction = ParameterDirection.Output;
theCommand.Parameters.Add(p1);
theCommand.Parameters.Add(p2);
theCommand.Execute( ... );
firstValue = p1.Value;
secondValue = p2.Value;

I wrote a class named Region, which encapsulates the content of a part of the screen.
Region keeps two Bitmap objects: content, and lastContent,
and it compares them via this code:
private void checkForChange()
{
for (int y = 0; y < bounds.Height; y += 10)
for (int x = 0; x < bounds.Width; x += 10)
if (content.GetPixel(x, y) != lastContent.GetPixel(x, y))
{
userCallBack(this);
return;
}
} In the main program, I have an array of Region object, each representing a different part of the screen.
I use a new thread for each region check, and when a check is finished, I reactivate it.
However, this consumes a great deal of CPU.
Task Manager shows between 15 to 25 CPU usage.
Any ideas regarding how to decrease the CPU usage (not at the algorithm level)?
Thanks,
Shy.

You could set the priority (something like ThreadPriority on the Thread class) of the thread lower.
Other then this using GetPixel is rather slow. Have a look at this[^] article series on how to do it faster.

Thanks! Looks good!
I'll get right on to it, and come back here with my future questions
Thanks again!

Well...
I tried using pointers like the article described...
Didn't help much...
This is my new code:
private void checkForChange()
{
Rectangle r = new Rectangle(0, 0, bounds.Width, bounds.Height);
BitmapData dataContent = content.LockBits(r, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);
BitmapData dataLast = lastContent.LockBits(r, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);
int stride = dataContent.Stride;
int offset = stride - dataContent.Width * 3;
int width = dataContent.Width * 3;
int height = dataContent.Height;
unsafe
{
byte* pContent = (byte*)dataContent.Scan0;
byte* pLast = (byte*)dataLast.Scan0;
for (int y = 0; y < height; ++y, pContent += offset, pLast += offset)
for (int x = 0; x < width; x += 3, pContent += 3, pLast += 3)
if (pContent[0] != pLast[0] || pContent[1] != pLast[1] || pContent[2] != pLast[2])
goto Found;
}
Cleanup:
content.UnlockBits(dataContent);
lastContent.UnlockBits(dataLast);
return;
Found:
userCallBack(this);
goto Cleanup;
} It even uses more CPU...
Ideas?

Hello all,
in my Win Applicaiton. i am using TabControl. In this I added 2 Tabs. I want to disable second tab. It is not having Enabled Property.

TabPages have the Enabled property
TabControl1.TabPages(1).Enabled = False
|
|
|
|
|
Is that possible to Program the tab control's button, which appears on the top and are associated with the tab pages?
_____________________________
Success is not something to wait for, its something to work for.

If you want to do this at runtime(which it sounds like you do), all you need to do is set TabControl.Tabpages[].Enabled = false. If you want to do it upon changing tabs, you can handle the TabControl.TabIndexChanged event or any of many other TabControl Events[^].

You can't
Have a search on CodeProject for "editable ListView", results 1 and 3 might be what you're after.

Have a look through regexlib[^] and you'll probably find several ones. Another one is the RegularExpressionValidtorControl in ASP.NET has some built in ones, it may be in there.

Rizwan Rathore wrote: want to know about the RegularExpression class of C#
Best place is the documentation provided by MSDN[^]
Ok basically you want the System.Text.RegularExpression namespace, the most important class is RegEx which handles all the matching etc. There is a constructor for this class which takes the regular expression pattern (for the URL in this case) and creates a RegEx object based on it. If you then want to check for URLs you can use:
IsMatch - Checks if a string, or part of the string specified in the parameters matches the regular expression provided in the constructor.Match - Returns a match object which contains the first match that the class found matching the regular expression.Matches - Returns a collection of Match objects for each regular expression matched correctly. If the regular expression is enclosed in parentheses then the url can be extracted by using the Group collection.
Example: This simple code will extract all the urls from a given string.
string urls = "there is a url included somewhere in this string : http://www.codeproject.com/script/comments/forums.asp?msg=1524600&forumid=1649#xx1524600xx and here is another url http://regexlib.com/Search.aspx?k=uri";
string urlRegex = @"(?<url>(mailto\:|(news|(ht|f)tp(s?))\://){1}\S+)";
Regex regex = new Regex(urlRegex);
foreach (Match m in regex.Matches(urls))
{
Console.WriteLine(m.Groups["url"].Value);
}
Console.ReadLine();
