You probably forgot to link to the correct library (the sqllite library). Have you done that in your project settings ?

hi.. i've already added the required sqlite3.h header file yet the error messages are not resolved. Can you please help me on that. This is my coding:
// SQLITE1.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <stdio.h>
#include "sqlite3.h"
static int callback(void *NotUsed, int argc, char **argv, char **azColName){
int i;
for(i=0; i<argc; i++){
printf("%s = %s\n", azColName[i], argv[i] ? argv[i] : "NULL");
}
printf("\n");
return 0;
}
int main(int argc, char **argv){
sqlite3 *db;
char *zErrMsg = 0;
int rc;
if( argc!=3 ){
fprintf(stderr, "Usage: %s DATABASE SQL-STATEMENT\n", argv[0]);
}
rc = sqlite3_open(argv[1], &db);
if( rc ){
fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
sqlite3_close(db);
}
rc = sqlite3_exec(db, argv[2], callback, 0, &zErrMsg);
if( rc!=SQLITE_OK ){
fprintf(stderr, "SQL error: %s\n", zErrMsg);
sqlite3_free(zErrMsg);
}
sqlite3_close(db);
return 0;
}

A .h file is not a library file, it's a header file. You need to have a *.lib file to be added in your project settings: in the linker category, you need to add the name of the lib file in "Additional Dependencies" or something like that (I don't have VS installed on my PC here so I can't give you the exact location, but search a bit and you'll find it).

I'm using visual c++ for the project and already added the sqlite3.dll file. The same error occurs again. I have no idea where it went wrong..

I'm talking about a .LIB file, not a dll file. Did you add this lib file in your project settings (3rd time I'm asking) ?

Yes (and it possibly returns 09034 for your input).

Thanks for the reply , but is there any function to do that ?

You can roll your own one. What are your doubts while doing that?
I recall for you the needed steps (if you aren't using MFC or ATL). You have to:
- Parse the string to obtain
day-of-month, month and year from the string. - Convert
day-of-month and month to day-of-year. - Align properly
year and day-of-year values in the resulting number.
In the above task, only point(2) is a bit tricky because of leap years.
Using MFC or ATL would make your life easier.

just use scansf grab the constituent parts and throw it into a SYSTEMTIME struct.
Just rember that scanf assumes int * and the systemtime struct is all word size objects.

DWORD Month,Day,Year,Hour,Minute,Second;
//Initalize the values and the structure to zero
Month = Day = Year = Hour = Minute = Second = 0;
memset(&ST,0,sizeof(ST));
//Fix This use the stram reader so I can read the write size
//Parse out the date with sscanf
sscanf_s(Val.c_str(),"%d/%d/%d %d:%d:%d ",&Day,&Month,&Year,&Hour,&Minute,
&Second);
//reassign the values into the structure
ST.wDay = (WORD) Day ;
ST.wMonth = (WORD) Month ;
ST.wYear = (WORD) Year ;
ST.wHour = (WORD) Hour ;
ST.wSecond = (WORD) Second;
ST.wMinute = (WORD) Minute;

it depends on what you mean by julian date - since the term is most often miss-used these days.
If you mean 'the day number as a number starting counting from the 1st of Jan in the Current year', then you need to follow the advice of our trusted and esteemed colleague CPallini
If you mean since an arbitrary point in time - such as is used by astronomers etc, ie 4713BC, then, part one of CPallini's response still applies, then you feed the results of the parse into something like :-

Use SendMessage to send the EM_SETBKGNDCOLOR message to the rich edit control.
Look at the documentation for EM_SETBKGNDCOLOR on how this is done.

Hi
I need to log a warning message if count of similar active X controls on a window is greater than 10. I have the window name with me. I need the logic to count the Active X controls on same window.
Thanks.

I suppose (it's just a guess, however) you simply cannot do that.

Hai!
In the Resource view of my application there are folders such as Dialog, String table, Icon, Version. If i click the version a window appears which contains the updated values of file version and product version etc.
How can i programmatically get this value of product version as i need it to display in an AfxMessageBox. Is there any function to access this value of Product version.
Thanks!
