Here is a code I wrote to log all clipboard text in the log file.

#include <windows.h>
#include <iostream>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

using namespace std;

void myfree();
FILE *fp;
char *p;
HANDLE clip;

int main()
{
HANDLE clip;
p=(char*)malloc(1);
*p='\0';
fp= fopen("log.txt", "a");
atexit(myfree);
if (OpenClipboard(NULL))

while(true)
{
clip = GetClipboardData(CF_TEXT);
if(strcmp(p,(char*)clip)!=0)
{
free(p);
p = (char*)malloc(strlen((char*)clip)+1);
strcpy(p,(char*)clip);
fprintf(fp,"%s",p);
}
Sleep(500);
}

}

void myfree()
{
free(p);
if(fp!=NULL)
fclose(fp);
free(clip);
}


The code runs fine. But as the program runs, why can't I do as usual
copy-paste stuff ??

"The OpenClipboard function opens the clipboard for examination and prevents
other applications from modifying the clipboard content. "

.... so you are preventing other applications from using it.

Change your code to close the clipboard again....

while(true)
{
if (OpenClipboard(NULL))
{
clip = GetClipboardData(CF_TEXT);
if(strcmp(p,(char*)clip)!=0)
{
free(p);
p = (char*)malloc(strlen((char*)clip)+1);
strcpy(p,(char*)clip);
fprintf(fp,"%s",p);
}
CloseClipboard();
}
Sleep(500);
}
