Hi, your answer was helpful. I have editted my question for another query in continuation this.
Thanks!

Yes, I have an interface to create the database i.e the ASP.NET Enterprise Manager but I havem't been able to figure out where to install the .sql scripts in there. Actually, there's a small icon named 'query'. Is that to be used for the SQL Script? Here's the screenshot of the interface I have for creating the database. http://i.imgur.com/LL9xy.jpg

Oh come on! I have already tried that and I have also tried to build through the binaries.

I put up the include guards but the protected memebers are shown still out of scope. Screencap: http://i.imgur.com/x2NcJ.jpg

@Aescleal: Just did that but to no avail. Screenshot: http://i.imgur.com/A9KAs.jpg

@Aescleal: I already tried to include List.h in Sortbale_list.h but then it starts giving huge number of errors related to redefinition of what I have defined in List.h.
P.S I am on Console application in Code::Blocks.

@John: I am coming from Umbraco forums itself and I didn't get the answer of the query there and I am still trying to find the solution on Google.

If it would have been compiling for me, I wouldn't have been asking this. Screenshot: http://i.imgur.com/bc2mx.jpg

List():count(0){}
Link to full code is in the post above

Ok, I was able to store the values in the session using the List but how do I have to retrieve these values?

Actually, I figured out that the RoundedCorners Extender in the AJAX Toolkit didn't apply to Button Control. So, now I have used Custom CSS buttons. But there's one problem: Earlier, I had the button control performing the code-behind operation. Now, I have a HTML button. How can I accomplish the same code-behind process now?

:P Thanks SAKryukor for help earlier. I also read a reply by Emilio at one of your comments. He was so true about me having taken some wrong step some time back and then now for(;;)Retry();
Perhaps, one day, I'll start answering questions here instead of asking! :P

:P So, at last I did that!
bool empty()const // that's it :P
{
}
I do have any tutor/teacher/instructor since I am a non IT student but I do understand that doing thing oneself if the only way to learn program
Thanks!

It turns out that there is another error here in retrieve method if(empty()) return underflow; after changing to data.the_key(). :(
The error: passing 'const List' as 'this' argument of 'bool List<List_entry>::empty() [with List_entry = Key]' discards qualifiers|
It is rather not my mistake and I am tired but I was just following text book to learn these basics. Nae of text book: Data Structures and Program Design in C++ by Robert L Kruse, Alexander Ryba.

I changed that to List< Record > the_list; and the_list.retrieve(p, data);
but it gives me a strange error : no match for 'operator<<' in 'std::operator<< [with _Traits = std::char_traits](((std::basic_ostream<char,> >&)(& std::cout)), ((const char*)"Record value: ")) << data'|

I didn't downvote anybody! Why are getting annoyed with me over that :-(

uh! I can't format the comment above properly. :-(

Ok, now I get this totally.
Thanks a lot for help!!

How? Is it available in Code::Blocks because I am trying applications on console.

Hi Manfred,
Thanks for being so cooperative and I really appreciate this. If you'll still allow me to ask, why can't we compare return (x==y) just like this. Why do we even need to use int the_key()const; ?

Ok, that atleast compiles now but
1) What does this single colon mean here? List(): count(0){}
2) From the main program, I haven't been able to insert values to the List. Retrieve too gives some error.
If needed, I have uploaded the project here: http://www.4shared.com/file/D1sjC8ta/SequentialSearch.html

@jk chan: I tried to put function and implementations both in one file but its giving too many errors.
Here's the code of List.h -> http://pastebin.com/kJkuzXRV
And here's the code of main.cpp -> http://pastebin.com/8hyiGtqi
Btw, I am trying a Win32 console on Code::Blocks

I am confused what's x.the_key(); doing?
int the_key()const; is only defined in the class .h file and there's no more mention of it in the example from a book I am trying the program. It only mentions the_key is being used to inspect a copy of key's value. A little bit more explanation would make this more clear to me.
Thanks!

But
for(int i=0;i==5;i++)
{
cout<<i;
}
doesn't give me anything in the output.

Yes, I did mention the enum code at the top of my Stack.h class definition like this:

const int maxstack=10;
enum Error_code { success, fail, range_error, underflow, overflow, fatal,
not_present, duplicate_error, entry_inserted, entry_found,
internal_error };
class Stack
{
public:
Stack();
bool empty()const;
Error_code pop();
Error_code top(Stack_entry &item)const;
Error_code push(const Stack_entry &item);
private:
int count;
Stack_entry entry[maxstack];
};

but in Stack.cpp, I am still getting errors "success was not declared in this scope."

My second doubt: I have to make this Stack_entry generic by allowing the user to mention define in his code like typedef char Stack_entry; but if I remove this from Stack.h, errors are: "Stack_entry does not name a type"

So, for char and string getline has different syntax?
For char- cin.getline(ch,256);
For string- getline(cin,text,'\n');
Is it?
Then what's the difference between cin.get(text,'\n'); and cin.getline(ch, 256); ?

Where is this Error_code definition mentioned? In the global part of the Stack.h definition file?
I tried mentioning this enum in the global part of Stack.h but Stack.h says 'success' was not declared in the scope.

Also, in my Stack.h file, I have mentioned at the top typedef char Stack_entry, but that makes the Stack only to take char values. If I do not declare this in Stack.h file but do this in main.cpp by the client code, then I get error saying Stack_entry does not name a type.

Ok, I get this
One is C style pass I was using and the other is C++ style pass by refernce.
Thanks for the nice link. Its really cluttered sometimes on the web. :)

Yes, it was an enum and it was a text example from the Data Structures book I was referring to learn all this.

That actually did solve but what I earlier used getline was like this: cin.getline(ch,256);
How should I have known to use getline(cin,text, '\n')? :-/

So, basically both of my above functions were call by reference? Although pointers use should be avoided?

#include <iostream>
#include<string>
#include<cstring>
using namespace std;

int main()
{
string text;
cin>>text;
cout<<text.length();
return 0;
}

Input: How are you?
Output: 3

I don't think text.length() is counting the whole string when I giving a string at the runtime...
However, if I write string text = "How are you?", then it will give the answer as 12.

A console app

You mean text.length() is not correct? or text.length() does count length of the string including spaces?
(btw, I am trying Win32 console and not MFC)

Ya! trying programs from the book but sometimes mess up... :-/

I actually wrote the problem in the code comment. Sorry about this :|

Actually, that puts up two elements extra in my reversed list. So, if enter 2 3 4 5 6 7.
I get the output 7 6 5 4 3 2 1 0.

As I read somewhere, when we declare stack < int > numbers , we are doing an implicit initialization of the stack and the stack is automatically initialized to be empty.
Secondly, if I try I simple program to reverse the int list, numbers.top() and subsequently numbers.pop() work properly to give the desired result.

It crahes as soon as run this. (using CodeBlocks)

Oh thanks again! Actually learning this stuff myself!

:O
Does that mean
for(i=0;i=5;i++) - Invalid
for(i=0;i==5;i++) - Invalid
for(i=0;i<=5;i++) - Valid

It doesn't even take the input at the beginning and neither give any error message.
I uncommented a part in the main to see the working of only configuration::initialize(). But no input is accepted and no output is given.
If required, here's the downloadable project. (271 kB) http://cid-7cfad5624f27df6f.office.live.com/self.aspx/.Public/GameofLife.zip

No, its not the Visual C++

And could you please help in the other two problems too?

How do we store color in the XML file.
I think color is not serializable and we have to make the Color class serializable but how how do I do this in this sample.
Thanks!

Although, I have set the SizeMode if Picture to Zoom, but still the loaded pictures come in size smaller than the size they were saved?
What am I doing wrong?

Many thanks for your help!
I had further question regarding storing a .wav in the same XML file.
A picture box can have a Tag associated with it or a 'Recorded .wav'.
The recorded wav comes from Form2.
If the user records the sound and even gives the tag to the picture, then preference is given to the saving/playing the sound.
How do I save and load this wav in the XML file?
Thanks!

I had already tried that. The panel I have used has TableLayoutPanel inside it. Panel's Auto size property is true. When the Panel is anchored to Top, Left (by default), the TableLayout forms rows and columns which are equal in width and height.

However, when I anchor the Panel to all the sides, the TableLayoutPanel inside the Panel doesn't form rows and columns which are equal in size. Any suggestions.

As I answered to Rajiv Lipu's post, the problem remains the same.

In other case, if I would have use a 'Panel' which has a TabIndex property. I wanted to set the TabIndex property of the Panels starting 0 from the first Panel created in the above code and 'last' for the last Panel created.

PictureBoxes don't have TabIndex property. :-|

Tried, but it remains the same. :-|

Hi,
Thanks for the reply.
The images problem is solved but the main issue now is that on pressing the "Start Recording button", nothing happens and similar is the case with Stop Recording. Play button also doesn't do anything :o/

Hi,
Thanks!
Thanks a lot for the ingenious sample. I improvised the program a bit but Load is not operative correctly in my program.
Here's a sample program in which I tried things.
http://www.mediafire.com/?wcb4btj0p83zm5z

P.S Apart from this (off topic), if you could also look for slight modifications that might be needed in the program such as TableLayout Dock problem, anchor problem with controls, TableLayout Cell Width and Height adjustment, Fitting an image into the PicBox etc.
Sending the picture back to the picture box worked in my program. However, I wasn't able to send the Label back to the corresponding cell in which each it is contained (in Form1). Further, I have also have to send the Text from Form2 as PictureBox Tag in Form1.

I would be greatful for help.
Thanks a lot!

Thanks a lot for the efforts!
I needed to clarify somethings. Hope you won't mind answering them

In the Form1 code, wherever, I have used the Output class,
Output.Save("output.out");
Output.Person
Output.Load("output.out")

gives me an error:
Error: An object reference is required for the non-static field, method, or property 'YourNamespace.Output.Save(string)'

I know it feels like spoon feeding but I haven't been able to do it. I am not a pro and the learning process is still stumpy :( :(
It would be more valuable if you could amend the above sample (link in my original post) according to your notion.

"List<customer> customer_list;
while saving the list in Xml (Simple Serialization) you can change the index according to the position in the TableLayoutPanel and you can keep track."

Actually, I wasn't sure on how to change the index for different columns and rows in the TableLayout.
I would be really very thankful if you could modify the above program accordingly to save and load contents to make that evident.

Kindest Regards
