Why don't you widen them (you can also set them for a blocking call, just to make a test)?

even if i change the values of commtimeouts to
GetCommTimeouts(m_comPortHandle, &sCommTimeOuts);
sCommTimeOuts.ReadIntervalTimeout = 100;
sCommTimeOuts.ReadTotalTimeoutMultiplier = 10;
sCommTimeOuts.ReadTotalTimeoutConstant = 500;
sCommTimeOuts.WriteTotalTimeoutMultiplier = 10;
sCommTimeOuts.WriteTotalTimeoutConstant = 100;
SetCommTimeouts(m_comPortHandle, &sCommTimeOuts);
i dint observe any change.

how can i multiply two numbers without using * operator, rather by doing bits manopulation??? plz help me out!
|
|
|

multiply/divide by how many ?
there's a hack if you multiply/divide integers by 2.
shifting the bits to one position left will multiply by 2.
shifting the bits to one position right will divide by 2.
however, if you're handling floats, this is a useless pain buddy.

Google "Bit shifting" and how base-2 number systems (uh, dat be called binary) sometime...
Peace!

If you are trying to multiply integers you can use addition in a loop, but without knowing more about what you want to acheive I do not think anyone here can really help.
Try to explaion why you need to do this and what you are trying to acheive.
Good Luck,

Try something like this, it's just the same as you do it on paper:
#include "stdafx.h"
#include <iostream>
using namespace std;
unsigned int Multiply(unsigned int l, unsigned int r)
{
unsigned res = 0;
while (l!=0 && r!=0)
{
if (r&1)
{
res += l;
}
l <<= 1;
r >>= 1;
}
return res;
}
int main()
{
cout << "1234 * 2:" << endl;
cout << "\t* = " << 1234*2 << endl;
cout << "\tMultiply = " << Multiply(1234, 2) << endl << endl;
cout << "314159 * 33:" << endl;
cout << "\t* = " << 314159*33 << endl;
cout << "\tMultiply = " << Multiply(314159, 33) << endl << endl;
return 0;
}

i have added the following code to create status bar in a dialog.
But its not getting created.
what could be the problem
....
m_StatusBar.Create(this);
m_StatusBar.SetIndicators(indicators, sizeof(indicators)/ sizeof(UINT));
....
|
|
|
|
|
Check this article[^].
BTW, I searched for "dialog status bar" on the codeproject search and that was the first result 
|
|
|
|
|
Yes. its good sample.
Meanwhile i am getting the following error.
error C2664: 'void ATL::CStringT<BaseType,StringTraits>::Format(const wchar_t *,...)' : cannot convert parameter 1 from 'const char [10]' to 'const wchar_t *'
How to resove this.

It is because UNICODE is defined for your project. I suggest this excellent article[^] if you want to understand what is happening. If you don't care, just disable UNICODE in your project settings (but you'll miss a chance to learn something usefull).

Thanks.i gone thru the article.
Look below decl. of unicode.
wchar_t wch = L'1'; // 2 bytes, 0x0031
wchar_t* wsz = L"Hello"; // 12 bytes, 6 wide characters
First stmt one char -> 2Byte.
Second stme five char -> 12 byte. How?

It seems that you didn't really understand the article  . wchar is a wide character, which means each character is coded on two bytes. So, the string "Hello" (with the terminating character) is 6 wide characters so 12 bytes.
BTW, don't use wide characters directly but use TCHAR instead. In this way, your code will support both unicode and non-unicode builds.

i actually confused with the first stmt as it has one char and another(termin char). so total would come 4 bytes. 
|
|
|
|
|
No: it is not a string. It is a single wchar, so its size is 2 bytes.
|
|
|
|
|
Again and again i am struck with unicode and multibyte char convesions.
int iValue = m_iValue1;
CString str;
str.Format("%d", m_iValue);
.....
.....
m_ListBox.AddString(str);
.....
How to do that using TCHAR? like format used in CString..

Did you get this resolved? (I just implemented it in about 5 minutes w/ that article)

Hi all,
From VC++ code i am calling a stored procedure that is updating some fields in the data base
the code is working fine for sql2k but throwing following exception for 2k5
Error Message: Multiple-step operation generated errors. Check each status value.
Failed to update column XYZ with value: 1
Column Attributes for Receive_Status: [Field accepts null values][Null values can be read from the field][Field contains fixed-length data]
Field Status for Receive_Status: [Value violated the data source schema constraint for the field]
Please help me here ...
am having a suspect on a variable of stored proc that is used as tinyint ...
please help me here ...
Thanks
