Hi all,
Cant we hide a CLabelControl after declaring a variable..???
I am getting a run time error for this.
Test.h
CLabelControl m_Test;
Test.cpp
DDX_Control(pDX, IDC_LABEL_TEST, m_Test);
BOOL CExampleDlg::OnInitDialog()
{
CLabelControl* lTest;
lTest=(CLabelControl*)GetDlgItem(IDC_LABEL_TEST);
lTest->ShowWindow(SW_HIDE);
return true;
}
If i comment
//CLabelControl m_Test; in Test.h
//DDX_Control(pDX, IDC_LABEL_TEST, m_Test); in Test.pp
Then it runs without any error.
Can anyone have any idea
Thanks in Advance

Your label control does not exist at the point you are trying to hide it.
You need to call CDialog::OnInitDialog in your OnInitDialog method before the control exists.
BOOL CExampleDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CLabelControl* lTest;
lTest=(CLabelControl*)GetDlgItem(IDC_LABEL_TEST);
lTest->ShowWindow(SW_HIDE);
return true;
}
Hope that helps.

Dear all,
can any one provide me the "C source code for A* algorithm"
|

Dear Friend,
From my PC, I have to read the text file from another PC(server PC).
After that i have to invoke one "EXE" (application) present in that same PC(Server PC).
Then i have to send the information what i have read from that file to this application.
Kindly help me.

Are both PCs on the same network and able to share disks? If so you can just read the file and execute the program from the server's shared disk.

hi all,
can anybody help me to extract plain text from html file?
thanks.
|
|

A very simple parser would:
- Get the used character set from the header
- Locate the next < char, locate the next > char behind, and delete all in between.
- Replace the HTML entities &, <, >, and " by the corresponding chars &, < >, and ".
- Optional replace other entities by the corresponding characters according to the used character set.
- Optional replace Unicode code points (&#[x]cp;) by the corresponding characters according to the used character set.
- Optional convert the resulting text to the required output character set

thanks a lot. Do I have to install visual studio 2008 for converting my visual c++ 6 (2003) ?
Please give me some guidances.

I dont have much idea on that. Like you i am also new to this. The only difference is i searched the net first and i send you the link which really suited your query. There are other sites which gives you a very good insight on how the migration has to be done.

Create a project in VS2010, add the source code from C++ 6 and build the project. Fix all warnings and errors.

You just need to jump right in and convert it. There's no magical way to do it and the number of warnings and errors you get depend on what your source code has in it and how well you coded according to standard (old compiler used to let you get away with using non-standard C++, new one is better about that but still, MS refuses to follow standards strictly, they implement things they want regardless of current standards).
...oh, and don't forget to save a copy of your unchanged code for reference or if you need to fall back to your original code. If you have source control, create a tag to save the location.

Like others have stated. Just open the project or solution in vs2010 and let it convert and backup. Then start walking down the list of errors one at a time. If it's just vc++ and no extensions it should be easy.

Dear Developers,
Todays I found a surprsing fact on the scenario of functiona overlaoding in C++.
The code segment is here
#include <iostream>
using namespace std;
void display( char* );
void display( const char* );
void main()
{
char *ch1 = "Hello";
const char *ch2 = "Bye";
display(ch1);
display(ch2);
}
void display( char* p )
{
cout << p;
}
void display( const char* p )
{
cout << p;
}
As I know, In function overloading, the arguments must be differ in either in type or count. But its working. and one more surpring fact is that if I am remving pointers on that program. It says.. that function already have a body.
How is it possible????
Please guide me.
Thnaks.

Use code tags when you post code.
What do you mean by "removing pointers"?

The arguments to the methods have different types.
And do you have warnings turned on to the highest level in your C++ compiler?

Hi, Amrit,
It's working because it's legal to overload functions based on whether the argument refers to a const or non-const type.
So,
void display(const char*) is overloading
void display(char*)
And you're correct. The following couldn't be overloaded. It won't compile because of const conversion used by compiler. It can't figure out which one is the best match.
void display(char);
void display(const char);
void display(char const);
(Technically, the above are redeclaration. It's fine to just define the third one by adding function body. But it won't compile if all of these three functions have function bodies or definitions.)
By the way, to be clearer, the following won't compiler neither because of the same reason.
void display(char*){...} void display(char* const){...}
