Did you try asking this question in any of the InnoSetup forums? You may get more help over there instead of trying to reframe the question and posting it here time and again.

Hello all
I had written a small program to print ones compliment of zero in visual studio, and got the result as -1. I am surprised to see this result. because what I expect was ~0 = 11111111 !!!
Y it is -1 ? 
Thank you

Yes, in binary  . You are probably storing the result in a signed variable (e.g. an integer or a char). And for a signed variable, if all bits are set, the resulting value is -1.

Hello , Thank you
in VC++ how can we print the right value ?
|
|
|
|
|
And what is, in your opinion, the right value?

in my opitions, if it a unsigned int, it should be 2 ^32 -1
|
|
|
|
|
Then store the result in an unsigned int and display it. What's your code ?
|
|
|
|
|
here is my code
int main(int argc, char* argv[])
{
unsigned int i = 0;
printf("%d",~i);
return 0;
}
|
|
|
|
|
Use %u instead of %d. %d is for signed integers and %u is for unsigned integers.
|
|
|
|
|
The flawn is in %d format specifier. According to documentation [^] %d specifies 'signed decimal integer' hence you unsigned number is first converted to signed and the printed out.

Good. The following snippet may possibly confirm you opinion
void main()
{
unsigned int u = 0;
u = ~u;
printf("%u (%x)\n", u, u);
}

Code:
#include <stdio.h>
#include <stdlib.h>
int main()
{
char myVar = 0xFF;
printf("Signed: %d\n", myVar);
printf("Unsigned: %d\n", (char unsigned)myVar);
system("Pause");
return 0;
}
Output:
Signed: -1
Unsigned: 255

Hi all.
I want to change a date format from dd/mm/yyyy to yyyy/mm/dd..
suppose i am getting date as..
Date = 12/04/2008 i want it to be changed to 2008/04/12..
I am trying with the below code but i am getting the system time..
the code is
CString Date,Datee;
Date = "12/05/2008;"
SYSTEMTIME sysTime;
GetSystemTime(&sysTime);
Datee.Format("%04d%02d%02d",sysTime.wYear,sysTime.wMonth,sysTime.wDay);
can anyone help me

It would help a lot if you would tell us what this date is: is it stored in a plain string, a COLEDataTime object, ... ?
Don't you have the different elements of the data (day, month and year) separately available ?

Gets the current system time in UTC
manju#123 wrote: I am trying with the below code but i am getting the system time..
because you are using the system time and just formatting it before displaying
manju#123 wrote: Datee.Format("%04d%02d%02d",sysTime.wYear,sysTime.wMonth,sysTime.wDay);
Do you try to print the Datee string after the string is formatted? It should now be in the format you need.

Try using GetLocalTime...

If you are talking about Date variable then you can get the desired format using -
CString Date = "12/05/2008";
CString YY,MM,DD;
int nLen;
nLen = Date.ReverseFind('/');
YY = Date.Right(nLen - 1);
Date = Date.Left(nLen);
nLen = Date.ReverseFind('/');
MM = Date.Right(nLen);
Date = Date.Left(nLen);
DD = Date;
CString sNewDateFormat;
sNewDateFormat.Format("%s/%s/%s",YY,MM,DD);
And if you are talking about the variable Datee, then the code written by you is fine.

No surprise there since you are explicitly using sysTime members.

Yes. To get your yyyy/mm/dd format, use:
Datee.Format("%04d/%02d/%02d", sysTime.wYear, sysTime.wMonth, sysTime.wDay);Now if you are actually wanting to use the date in the Date variable, try:
CString Date = "12/05/2008";
COleDateTime dt;
dt.ParseDateTime(Date);
CString Datee = dt.Format("%Y/%m/%d");

Hi all,
While adding a variable to a control in the dialog it is not getting reflected in the class.Please kindly help me out
Thank You
|
|

Try deleting the .ncb file and .clw file in your source folder and then reopening it. The intellisense goes wild sometimes.
BTW, how do you add the variable? using the class wizard and which compiler/version do you use?

Thanks a million.It was indeed intellisense prob.By right clicking the control,variable["Add variable"]was added.Version 6 is being used

Hi,
I intend to make a sample application in VC++ to using MySQL databases.
Can anybody suggest me where and how to start?
I am new to databases any help would be great.
Thanks in Advance!!
Regards,
Tony

Visit this page http://www.codeproject.com/KB/database/[^] and set the language filter to C++ and skill to Beginner. There are plenty of articles that may give you a lead to begin with.
Note that there would be nothing specific to MySQL, but they will all speak about databases in general.

1)First of all import msado15.dll into your workspace
#import "C:\Program Files\Common Files\System\ADO\msado15.dll" \
no_namespace rename("EOF", "EndOfFile")
2)Initialize COM libraries using
CoInitialize(NULL);
3) Create connection & record set pointers
_ConnectionPtr pConn("ADODB.Connection");
_RecordsetPtr pRst("ADODB.Recordset");
4) Open data base
#define STR_DATABASE L"DRIVER={sql server};SERVER=serverName;Database=datbaseName;" L"UID=sa; PWD=sa;"
HRESULT hr = S_OK;
hr = pConn->Open(STR_DATABASE, L"", L"", adOpenUnspecified);
if(FAILED(hr))
{
AfxMessageBox ("Error instantiating Connection object\n");
}
5)Execute Query and read values
try
{
CString strSQL("Select * From MyTable");
pRst->Open( _variant_t(strSQL),_variant_t((IDispatch *) pConn, true),adOpenDynamic, adLockReadOnly,adCmdText);
if(!pRst->EndOfFile){
CString strValue = (char*)(_bstr_t)pRst->Fields->Item["FieldName"]- >Value;
int nValue = (long)pRst->Fields->Item["FieldName"]->Value;
}
catch(_com_error &ce)
{
AfxMessageBox(ce.ErrorInfo);
OR
AfxMessageBox(ce.Description());
}
6)Close connection and record set pointers
if(pRst->State == adStateOpen)
pRst->Close();
if(pConn->State == adStateOpen)
pConn->Close();
7)UnInitialized COM library
::CoUninitialize();
