I used below project source code to make MHT,
http://www.codeproject.com/KB/files/MhtBuilder.aspx[^]
Below strings are problem.
1:
"<link[^>]+?href\s*=\s*(?<key>('|"")*(?<value>[^'"">]+)('|"")*)"
2:
"<i*frame[^>]+?src\s*=\s*(?<key>['""]{0,1}(?<value>[^'""\\>]+)['""]{0,1})"
3:
"(?<attrib>@import\s|\S+-image:|background \s*?(url)*['""(]{1,2}" & _
"(?!http)\s*/(?<url>[^""')]+)['"")]{1,2}"
In some links it takes between 2 and 10 minutes. it usually happens in external links.
WHY?
Thanx...

I don't know, but I suspect the doubled-quotes, try \" instead.
For getting hrefs I use:
"href\\s*=\\s*(?'quot'[\"'])(?'href'.*?)((?'sep'#)(?'id'.*?))?\\k'quot'"

Hi Riaz;
Are you mean get the Row Index? If so, hope this help
this.dataGridView1.KeyPress +=new KeyPressEventHandler(dataGridView1_KeyPress);<br />
<br />
private void dataGridView1_KeyPress(object sender,KeyPressEventArgs e)<br />
{<br />
int i;<br />
i = ((DataGridView)sender).CurrentRow.Index;<br />
}

Hi,
I want to develop some fancy controls like buttons, checkboxes. or can say extend the look of existing controls that are available in Asp.net 3.5.
Is WPF appropriate for it or i use GDI+ to develop my own controls.
|

Umm...Think you might be a bit confused. Asp.net is a web page technology. If you want to write or extend Asp.net controls, you have to do it in asp.net
WPF is the new client app user interface technology. It is nice and easy to write good looking custom controls in this, or modify the existing ones. But they are for Client apps.
GDI+ is the underlying technology that is used by Winforms. You can write custom controls with Winforms, and you can extend the existing ones. It's not as easy as in WPF, but it can be done. This is also for client apps only.
Silverlight is another web page technology that is related to WPF because it allows a subset of the XAML used by WPF. This also allows custom and extended controls. Silverlight is kind of like flash and requires a browser plugin to work.
(XAML is extensible application markup language, and is the XML style syntax used to define controls and layout in WPF and Silverlight).

Hi all,
In my application, i have one arraylist which will store graphicspath object (series of line), let said gp1 (contains points a1,a2,a3),gp2 (contains points b1,b2,b3),and gp3(contains points c1,c2,c3),. These graphic path will be drawn in one drawing area. I would like to ask that how can i know which graphics path was selected when mousedown event occur? Off cours, i have already get the particular mouse point,let said points b2.
And in this situation, does create a region have any help in my problem(i mean create a graphicpath region to determind whether the points is in the graphicspath object)?
any help or tips are welcome 
regards

Hi all,
I think i can use graphicspath.IsVisible(points) to determind whether the particular object was selected...
|
|

Hi!
To find out whether a given point is inside the region surrounded by your GraphicsPath, you can create a Region from your GraphicsPath (there's an appropriately overloaded constructor) and then use Region.IsVisible().
If you're interested in whether a point is on or near the outline of the region, use GraphicsPath.IsOutlineVisible().

I would like to know how to read the bits of a 32bit integer. Say I have 32bit int and I want to read the last 11bits and then 2bits before that. Do I do this:
11bits = (integer >> 21) & 0x7FF;
2bits = (integer >> 19) & 0x3;
Is this correct?
Thanks

If you meant the high order 11 bits and the next two lower order
bits, then yes that's correct.

Hi,I've got a doozy.
I am the only developer at a fairly large company with a very small IT department.
I was asked to write a small application (sends out notifications when contracts are about to expire - slightly more complicated than that.)
Our previous programmer had been in a word terrible, and since taking charge I had explained enough to my well-meaning but non-technical that he understands vaguely the benefits of OOP, doing things in a modern programming language, and library reuse. He came to me with a concern today - our VP, another well meaning guy but someone who hasn't programmed since the early days of COBOL - wants everything to be done in PL/SQL stored procedures to 'keep as much of our programming in one place' and to have 'fewer applications to maintain' (wtf, right?). My boss could not convince him otherwise and asked me to create a powerpoint presentation on the issue.
I am planning on the following slides:
Benefits of using a modern programming langauge:
Library Reusability (domain object libraires)
Maintenance Clarity
Maintenance Testing (automated tests)
Maintnenace People Cost (nobody programs in PL/SQL! where are they going to find people?)
Tools available (debuggers, etc.)
N-Tier Architecture
Why People Use Stored Procedures - for each one the premise, why its not exactly correct, and why it doesn't apply to us
--User authorizations to use certain ones (we have one user with all authorizations enabled)
--Speed (our bottleneck is overuse of ajax, plus its not really true)
--Security SQL/Injection (parameterized sql and sometimes our SPs build sql as text and then eval it - sigh)
Any advice for doing this presentation? I am really worried that if I have to do this in PL/SQL this is going to become a trend and I will have to quit.

I'm glad I'm not the only one here who dislikes stored procedures (or at least the blind overuse of them).
Let me preface:
Before .net I did most of my database application programming with SQL embedded in C, either with Oracle (PRO*C) or RDB.
But at one point I had to work on a project that used SQL Server (6, as I recall) and ESQL was not yet available so we had to use a horrible (consultant-written) library of ODBC routines. The result was that the only way to have transactions was to use stored procedures.
No one was happy about it and thought very nasty thoughts about the sales monkeys who said we'd do it.
While I realize that newer versions of SQL Server offer better security and reliability, I continue to distrust stored procedures:
A) While installing some of my stuff at a client's site, the client asked if I could make a slight change; I did, it was just a small change to a stored procedure... a change to production code outside of source control. I did remember to check in the updated code when I returned to the office, but I realized that any (properly authorized) person could change any of the procedures, perhaps maliciously. Such changes are much more difficult with compiled code.
B) Several times a stored procedure just disappeared! I have no idea how. This either doesn't happen with compiled code, or at least the program won't run at all if it does.
Performance:
A) I can neither confirm nor deny whether or not procedures are faster than queries in strings. I suspect they are, though at best it's only due to preparation time.
Unless you have a procedure that gets called a whole lot (which may well be the case with a Web page), I doubt it matters.
If a procedure gets called less frequently then you're not benefiting from any performance improvement.
If the preparing of a particular SQL statement proves to be a bottleneck, by all means wrap it in a stored procedure.
B) But also remember that a parameterized ADO.net SqlCommand, once prepared, can be reused many times.
So if you have a Windows Service that needs to execute a particular statement many times during its execution (which should last months) it need only prepare the statement once, just like a stored procedure.
On the other hand, if you repeatedly create and dispose an SqlCommand that executes a stored procedure lose out on much of the benefit of having pre-compiled the code in the stored procedure.
C) One of the benefits of a stored procedure is that you can perform some logic on the data without passing it out of and back into the database, but I wonder what percentage of stored procedure actually involve that.
D) Add to that the recent post that pointed out that if you begin the names of your stored procedures with "sp_", SQL Server wastes time looking for it among the system procedures.
E) I have also worked with people who insisted that "metadata" (stored procedured, functions, etc.) bogged down the database. (Crazy as that seems.)
Other points:
A) If I have an application installed at several client sites I can check the installed versions with directory commands.
B) I can deploy a change to client systems with copy.
C) A database restore won't wipe out SQL code in compiled code.
D) I have no idea why someone would write a stored procedure that merely returns a table of data; use a view for that.
I also use quite a few inline table-valued functions; they combine the best of both views and stored procedures.
Closing:
Don't just use stored procedures unthinkingly:
If the statement is a proven bottleneck, first try improving the statement, only make it a stored procedure as a last resort.
A pre-compiled piece of crap is little better than an ad hoc piece of crap. (And it may be more visible to the client.)
Conceptually, a "procedure" has more than one step, and perhaps control statements; if your code is one simple statement I doubt it should be a stored procedure.

I've got to admit, I'm one of the proc adherants. I put a lot of work into the procedures. With the "one liners" that simply do the CRUD I use procs because I have a code generator that creates the procs and the classes to service them. However most of my work goes into serious crunching of numbers in high volume and for this we need to use procs.
I had not considered the security issues of installed apps (I work for a corporate and you need 53 bits of paper to enter the presence of the production servers) based on procedures. I was aware thae using a framework like nHiberante can give you a DB agnostic application but would not consider using it for my apps.
Restore comes under the same criteria as the production server access! I have lost s a proc but thought it was just me, there you go! Having said that my DAL has a GetTableSQL and an ExecuteSQL so I'm not welded to procs.
Thank you for the food for thought, I will no longer go blindly forward!

SP can be harder to maintain, as it's not contained in a visual studio like solution or project. You literally have to search through all 150 SPs to find business logic, and the capability of renaming of column doesn't help.
