Hi guys!
I am developing a multi-thread application and one of my threads is somehow blocked by something and thus it will occupy some resource such as a file forever. Is there a way to find out which thread is being blocked and more important what resouce is being held by that thread?
At last and as usual, thanks for your patience and reply. :)
hi i am having threading issues in my vsto project
// code for function
var threadUpdate = new Thread(_fun){IsBackgroud = true};

threadList.add(threadUpdate);
// code for progressbar
Progressbar pb = new Prgressbar(){Title =@"abc"}
pb.Show()
it was working in perfect condition before i add wpf progress bar.
as the plugin has been running as single thread
can i ask how can running multi threading in outlook
thanks
I am using FindFirstChangeNotification API to monitor the changes happening in a particular folder.But how to exclude a particular file(present in the watching folder) change notification Only.
Hi,

I have a question about using subqueries in an Update statement. My example:
UPDATE TRIPS
SET locations = city + ', ' FROM (select Distinct city
from poi
where poi.trip_guid = trips.guid)
Is it possible to refer to main table value (trips.guid) in subqueries?
When i try to use trips.guid I get the error:
"The multi-part identifier "trips.guid" could not be bound."
I am trying to make a bar chart using tables, which I have almost accomplished to my liking. The last step I want is text over my image which represents the bar. Here is the code I have thus far for building my little bar charts:
$height = 50;
//build length
$width = 450;
$multi = $brewAvg / 5;
$width = $width * $multi;
print " <tr > <td > $count. <a href=\"$breweryURL\"> $brewR</a> </td> <td > <img src=\"blueBar.png\" width=\"$width\" height=\"$height\"> </td> </tr> ";
And this produces something like this:
You can see in the code how I simply calculate the length of the bar based on a breweries rating. What I want to do next is have the rating number show on top of each breweries on the left hand side. How would I go about accomplishing this?
Update:
I tried a tutorial I read here:
http://www.kavoir.com/2009/02/css-text-over-image.html
and I changed my code to this:
print "<div class=\"overlay\"> ";
print " <tr valign=\"middle\" > <td > $count. <a href=\"$breweryURL\"> $brewR</a> </td> <td > <img src=\"blueBar.png\" width=\"$width\" height=\"$height\"> </td> </tr> ";
print"
<div class=\"text\">
<p> $brewAvg </p>
</div>
</div>
";
And my css I added was this:
<style>
.overlay {
position:relative;
float:left; /* optional */
}
.overlay .text {
position:absolute;
top:10px; /* in conjunction with left property, decides the text position */
left:10px;
width:300px; /* optional, though better have one */
}
</style>
And it did put any of the value son top of my images. All the text is in a list above all the bars like this:
Hi, I have a PHP page with content that my users can view. When this page receives a POST request from a certain external URL, I'd like to redirect the user to another page.
The problems I'm' having are:
How can I monitor the page for requests being sent in an efficient way?
How can I actually redirect them since header() doesn't work.
Thanks.
That I got no idea how.
I need a function that the window height or the monitor configuration is larger than 1200, put a div position top = 1000px and else put in another position top = 800px
Hi all,
I want to write an application that will monitor the content of all open tabs in IE / FireFox and trigger event once particular data is displayed in the tab.
I would like to know if there is an API for IE/FF to set focus on particular TAB, so that once event is triggered I set focus on a relevant tab.
Thanks in advance
Will the following piece of code work as expected in a multi-threaded scenario?
int getUniqueID()
{
static int ID=0;
return ++ID;
}
It's not necessary that the IDs to be contiguous - even if it skips a value, it's fine.
Can it be said that when this function returns, the value returned will be unique across all threads?
I need to display the selecteditems in a label
I am using VB 2005
I set the selection mode to multi-extended
It did work selecting only one item with the following code:
me.xresultslabel.text= me.xlisttextbox.text.selectedItem.tostring
But when I tried to display more than one item using the following code:
me.resultlabel.text= me.xlisttextbox.text.selectedItems, I get the following string on the label:
system.windows.forms.listbox+selectedobjetcollections.
any help will be highly appreciate
Example for threading queue book "Accelerated C# 2008" (CrudeThreadPool class) not work correctly. If I insert long job in WorkFunction() on 2-processor machine executing for next task don't run before first is over. How to solve this problem? I want to load the processor to 100 percent
public class CrudeThreadPool

static readonly int MAX_WORK_THREADS = 4;

I've hit a wall. Does anybody know a good text editor that has search and replace like Notepad++ but can also do multi-line regex search and replace? Basically, I am trying to find something that can match a regex like:
search oldlog\(.*\n\s+([\r\n.]*)\);replace newlog\(\1\)
Any ideas?

I am building this application in java.
Thanks
I'm using an NSTextView to allow multi-line input. However, due to the nature of my app, users will be more comfortable moving to the next input element when they press TAB.
How can I make TAB exit the NSTextView, while keeping the newline behaviour of the Enter key?
Can someone explain the difference between:
lock (someobject) {}
Using Mutex
Using Semaphore
Using Monitor
Using Other .Net synchronization classes
I just can't figure it out. It seems to me the first two are the same?
I am doing an activity monitor based on date which is similar to stackoverflow Today,YesterDay,this week,Last week,this month,last Month..... Based on current date how to get start-date and end-date for all these Today,YesterDay,this week,Last week,this month,last Month in c#?
Both Page.Cache and Page.Application can store an application's "global" data, shared among requests and threads.
How should one storage area be chosen over the other considering scenarios of data synchronization in the multi-threaded ASP.NET environment?
Looking for best practice and experienced recommendation.
Hi,
I want to develop a function in PHP that checks how dangerous a SQL statement is. When i say dangerous i mean, certain symbols, characters or strings that are used to get data from a database that the user shouldnt see.
For example:
SELECT * FROM users WHERE userId = '1'
can be injected in several ways. Although i clean the params, i also want to monitor how safe the query is to run.
Thanks in advance
i want to write a function that prints multi-dimensional objects which are text (or integers, etc.) into <span></span> tags and arrays into unordered lists.
how do you make the function work recursively so that it prints everything regardless of what level it's at in the object?
thanks!
How would i monitor a MySQL to detect SELECTs which are running slowly? Having identified a poorly performing SELECT, how would i analyse it with a view to improving it?
