Extracting the content between the opening and closing elements of a HTML tag is a pretty common problem.
Have you made any attempt to solve the problem yourself, i.e. by searching the web?
If not, I suggest you do so. People who can't do basic research generally don't receive help in this forum.

Thanks for the suggestion.
I wish I didn't do research on the net so that I can deserved what you've said.
Anyways, I think I better get help from others rather than from those who help nothing.

I only help those that help themselves.
As you don't seem to be interested in solving the problem yourself and expect the solution handed to you on a place, you'll get no further help from me.

Frankly, i did spend half an hour solving it already before I posted for help. Just right 10mns after posting this, I figured out the solution.
You have to understand that not everyone is like what you've thought that when they face problem they just jump up straight to the forum for help!! They might have tried their best already before coming to the forum.
You might have thought that you are a great forum answerer, but without good attitude and respectful to others, you deserve nothing from us.

I don't want anything from you. I already know how to solve problems like yours. To be quite frank, judging by your skill level I doubt there's anything useful you could teach me.
I'm happy to help people who have demonstrated they're made a serious attempt to solve the problem they are asking for help with. I saw no evidence of this in your posts. If you want respect, first you have to deserve it.

I am just a freshman to the forum stuff and the IT Industry. I also do not expect to teach anything useful to master mind.
Hmm, probably I haven't yet made myself clear to show my attempt. But I don't know how serious is consider to be serious! If we have a scale for that, it's wonderful.

Correct. You haven't.
Bora Vuth wrote: But I don't know how serious is consider to be serious!
Demonstrating that you have made some attempt to solve the problem by yourself would be a start. Post what code you have written so far and indicate which bit is causing a problem. Post links to the articles you have read and indicate where you require further information. You didn't do any of these things. All you did was ask someone to provide you with a solution. To me, that sounds like asking us to do your work for you.

Obviously there isn't a scale. However, hopefully you understand how to frame your questions in the future.

Hello All,
You know when you go to a webpage lets say and you take the mouse over a link sometimes it pops up a yellow box with text in it. Does anyone know what that is called? Anyhow I wanted to do that in C# lets say when you take the mouse over a TextBox one of those yellow boxes will pop up with information about the box. I tryed searching the net for it, but not knowing what the name of what I'm searching for is; it gets really complicated. Thank you

You're looking for the ToolTip control, which is built-in to the Windows Forms library. If you're trying to do this on the web, then you need to look at for tooltip, alt, and title properties depending on the form element.

Hi,
I'm not new to programming, but fairly new to .NET (I'm an old timer). I've been teaching myself C# since I am an old C/Unix programmer and thought it was a better alternative to VB.
I've been scouting around for the last month to invest in a RAD tool, and there are some application generators that I have reviewed. So far I've checked out DeKlarit, DevForce, and IronSpeed. The latter is nice but I don't necessarily want to do web apps only. I also own Infragistics controls, so it must be compatible with them.
There is quite a price range in these three above, and they all seem to have their pluses and minuses, but I feel it would be worth the investment to get a tool to give me a jump start on some larger scale applications without the huge investment of time in developing my own home grown application framework. Plus at my skill level, my first cut wouldn't be very good anyway.
I would appreciate any comments from individuals with experience with the above products, what you think of them, what the strengths and weaknesses, and if you recommend it (please specify what version you own, i.e. basic, professional, enterprise). I would also like to hear about others that I haven't yet reviewed that you found to be preferable.
Thank you in advance!

I remember anticipating the arrival of FrontPage. When it finally arrived I jumped on it and WSIWYGed a page up pronto. Then I had to manually modify the code to apply a feature the designer didn't support. I opened the code for the first time, puked, closed FrontPage and never used it again.
IMHO Visual Studio is the premier development environment for doing Windows development. The small amount of code generators built into VS works for me. To generate the remainder of the code I invoke my brain and use the keyboard to generate the results.

I understand what you are talking about, but my situation may be different than yours.
I spent the last 15 years primarily as a Visual FoxPro independent developer, and I learned it from scratch, in my spare time. It took me two years. I developed into one the premier VFP developers in my region. Well, the writing is on the wall and Fox is dying a rather quick death now.
Back in the early days of my FoxPro experience, I bought a framework and just like you, found it full of fluff. But it did help me develop my own base classes that handled database issue, especially multi-user concerns. This was worth the price of admission alone. That set of base classes evolved over time but was used in nearly every application I wrote since then.
As as independent, I do not enjoy an employer sponsored educational process. I must get quickly productive. At 46, I do not have the energy level to moonlight after hours every day after my normal 60 hour week.
What I am hoping for is to find the best code generator for me, whatever it may be, then lift the hood and see what makes it tick. I'm a very visual learner and would quickly catch on and find ways to improve upon it. However, to start from scratch and figure out things like how to handle record contention when there are tools out there to produce a working copy for me, this is not a desirable route for me.
Thank you.

Ok well like I said I have no experience to tell you about but I have seen members on this site speaking well of Iron Speed. Good luck, oh and that writing about VFP was on the wall like 10 years ago.

LOL, yeah, I know. There was a mass exodus out of VFP when .Net was released leaving a giant vacuum of unsupported clients and abandoned applications. I've made tons of money since then filling this need and even to this day am extremely busy, but I got back on the leading edge with my Sharepoint 2007 experience. Now it's time to fill in everything in between and I should be in decent shape.
Thanks for your replies. Good luck.

Hello
I'm trying to pass a pointer array to a dll and get back and array of char **
I'm in the middle of the way because I already can get the first string pointed by my array
Concept : I pass an Id and a char ** to a DLL , the dll allocates his buffer and an internal char *array then assign that char * array to the passed pointer
What I do in Csharp
[DllImport("bcta.Dll")]<br />
static public extern int bctaGetName(IntPtr hBcta, UInt32 nAttID, ref IntPtr [] StrPtr);<br />
<br />
static public int TestName()<br />
{<br />
IntPtr hBcta = (IntPtr)0;<br />
UInt32 attrId = 1039;<br />
int count;<br />
IntPtr[] StrPtr = new IntPtr[8];<br />
<br />
bctaOpen(ref hBcta);<br />
attrId = 8967209;<br />
count = bctaGetName(hBcta, attrId, ref StrPtr);<br />
string aa = Marshal.PtrToStringAnsi(StrPtr[0]);<br />
bctaClose(hBcta);<br />
return 0;<br />
}
This is working fine for the FIRST string but my inPtr array is modfified by the DLL and it only contains 1 element at return however my count is 3
I miss something in the declaration but I can't figure out what ?

I strongly recommend wrapping native C/C++ DLLs in a mixed mode assembly using C++/CLI that then publishes one or more managed classes as an interface to pure managed languages. In this approach you can use native C/C++ to interface to the existing DLL simplifying the management of native types like pointers to pointers etc.

???? ! 
I'm sorry but I do not understand what do you my nor I can't see any solution to my current problem
I'm already using different function of that dll without any problem.
The problem here is how to declare an IntPtr to be modified by the DLL function
Example In C
char *ptr;
void function (char **ptr)
{
*ptr=calloc(10,sizeof(int);
}

Thank you
But your comments are not very usefull
This is how I do it in C
char **xptr;
bctaGetName (hBcta, id, &xptr);
// the ddl function will assign his own buffer to the adress so I can now read xptr[0],[1] etc...
// The question is HOW to do the same in Csharp (I can not declare a pointer to IntPtr) and if I give the ref of an IntPtr array I need to assign the Array before the call and that array will be lost into the call so only the first element will be usable !
|

I got it !!
Using pointer and unsafe !
static public unsafe extern int bctaGetName(IntPtr hBcta, UInt32 nAttID, out IntPtr** StrPtr);
unsafe static public int TestName()
{
char ch = (char)1;
IntPtr hBcta = (IntPtr)0;
UInt32 attrId = 1039;
int status;
IntPtr** StrPtr;
Routing.bctaOpen(ref hBcta, Environ.RoutingDataPath, ch);
attrId = 8967209;
status = bctaGetName(hBcta, attrId,out StrPtr);
string aa = Marshal.PtrToStringAnsi((IntPtr)StrPtr[0]);
Routing.bctaClose(hBcta);
return 0;
}
