Hi friends,
I've built a COM component using ATL.The component gets created succesfully,but i'm not able to see it in the registry(tried registering it manually useing regsvr32 and it said component registered successfully)..Any help will be highly appreciated.
Thanks and regards,
Rajeev

The registration wasnt so successful as displayed. Debug your COM registration code.

How can I convert dec to bin?
int i=123;
printf("dec: %i bin: ???", i, i);

This is some quick and dirty programming.

try to answer my question, i have put it under your first post.

Is it some kind of assignment to you? Anyways here is the code :
int ConvertDecimalToBinary(int i)
{
int temp = 0 ;
int counter = 1;
int binary = 0 ;
while (0 != i)
{
temp = i%2;
i = i/2;
binary += temp*counter;
counter*=10;
}
return binary;
}

and yes, printf("dec: %d bin: %d", i, ConvertDecimalToBinary(i));
and this function does have its limitations.

dear AnShUmAn
can your code get me answer for the integer 100?
please verify and reply
|
|
|
|
|
do you doubt it? why so
Then check it for urself.
I didn't try executing it and still it should work fine for all numbers that are within the int range whether it be 2 or 100.

it won't work for that number because the value being returned is an int and range for int's is upto 32767 and while performing the calculations the number (value "binary" being returned from that function) exceeds the limits. ie why I said that this technique is quick and dirty  . OPTIMIZE it

void DecimalToBinary(int number) {
int value;
if(number <= 1) {
cout << number;
return;
}
value = number%2;
DecimalToBinary(number >> 1);
cout << value;
}
Now it would............ and now don't say that it won't work for a negative number :->
Just do some error handling. I hope that this does work for you

did you know that itoa() was doing that kind of stuff by itself ?

It's a good thing, too. Otherwise you would have quickly realized your function does not "convert" its argument to base-2. The function will need to return some sort of char* or string in order to properly represent a base-2 number.

I've noticed a pattern ... Given my timezone in relation to most posts, every morning I
read through all last night's posts. There's mostly posts with 10 to 100+ fishing-derby-style
replies and then the one lonely reply by DavidCrow (or led mike) at the end with a one line simple
solution It's like a train wreck - I can't help but read them all LOL

Hi,
I know that it is possible to "protect" your application so that you can just see the top-level window of an app if you use Spy++ or similar. All child windows arent listed there (like Edit boxes, checkboxes etc).
If I want to get the state of a checkbox, the normal Message BM_SETCHECK is not usable.
What are the ways to protect the apps and is there a wor around to be able to send messages and get the state of a checkbox or read the text of an editbox?
Thats what I used so far for nonprotected apps:
#include "stdafx.h"
using namespace std;
#define TEXT_LENGTH 1024
char text[TEXT_LENGTH+1];
HWND hwndInfo = NULL;
HWND hwndEdit = NULL;
BOOL CALLBACK EnumChildWindowsProc(HWND hWnd, LPARAM lParam)
{
char pcControlClass[TEXT_LENGTH];
GetClassName(hWnd, pcControlClass, TEXT_LENGTH);
if( ::strcmp(pcControlClass, "Edit") == 0 )
{
TCHAR pcEditText[TEXT_LENGTH];
long len = SendMessage(hWnd, WM_GETTEXT, TEXT_LENGTH, (LPARAM)pcEditText);
if( len != 0 )
{
SendMessage(hWnd, WM_SETTEXT, TEXT_LENGTH, (LPARAM)"lala");
}
return false;
}
return true;
}
BOOL CALLBACK EnumWindowsProc(HWND hWnd, LPARAM lParam)
{
char pcWinTitle[TEXT_LENGTH];
if( !::GetWindow(hWnd, GW_OWNER) )
{
::GetWindowText(hWnd, pcWinTitle, TEXT_LENGTH);
if( ::strcmp(pcWinTitle, "HookTest123") == 0 )
{
EnumChildWindows(hWnd, EnumChildWindowsProc, (LPARAM)0);
return false;
}
}
return true;
}
int _tmain(int argc, _TCHAR* argv[])
{
EnumWindows( EnumWindowsProc, (LPARAM)0);
return 0;
}

Hi,
I have 5 projects say project1, project2...and project5. I want to compile these projects to my will as below when i try to build the entire work space.
First it has to buile project5,
then project3,
then project4
then project1 and
then project2.
all the projects are in the same work space in VS 2005.
I think we can do this is different ways...but I never tried any of this..so suggest me with is the best way.
1) Creating a BATCH FILE to compile the each project seperatly
2) Using MAKEFILE
3) May be..by doing some setting changes.
or any other way is avilable??
Thanks in advance,
Nandu.
