How can I load an image and play a wave file?
Thanks!

::LoadImage
::PlaySound
I'm not joking.
If you want to load something that's not a bmp, you need to either use GDI+ ( built in if you have VS.NET 2002 or 2003, even if you're not using managed code ). My articles explain how to use it, and how to set it up if you're stuck in VC6.

Is there a way/method to modify the current date value so that it will end up become the last day of the next month in c runtime library?
e.g.
Lets say date is 15/05/2005. After modification, it should become 30/06/2005 and then 31/07/2005 and so on.

Could you be more specific? Is it the system's time that you are trying to change? Or is it a file's or folder's access/creation/modification time that you are trying to change? Also, I would suggest that you take a look at time.h which is the a standard C library with date and time related functions. difftime function might be useful to you, and also the tm structure.

Actually, the standard file is called ctime. all C++ headers dropped the h when they were standardised ( i.e. iostream, not iostream.h ) and additionally, a C was prepended for the C runtime files ( so ctime, not time.h ).
The old ones are there for compatibility only, although in reality, because most people still use them, they are probably there to stay.

Technically yes, but the question mentioned C, not C++...

Well, i am using time_t and localtime(...).
time_t tDateTime;
time(&tDateTime);
tm *pstTM = localtime(&tDateTime); Base on the current date i got, i need to derive the date of the end of following month. I know i can modify the tm_mon and tm_mday values in the tm structure, then use mktime to get the new date but it is not accurate as each month has different number of days.

For that,You have to derive your own LOGIC. here is small piece of code to get started.
time_t tDateTime;
struct tm *pstTM,endDate;
int isLeap;
time(&tDateTime);
pstTM= localtime(&tDateTime);
printf("\nToday-%d/%d/%d",pstTM->tm_mday,pstTM->tm_mon+1,pstTM->tm_year+1900);
if(pstTM->tm_year%4)
isLeap=1;
else
isLeap=0;
endDate=*pstTM;
if(endDate.tm_mon==1)
{
if(isLeap)
endDate.tm_mday=29;
else
endDate.tm_mday=28;
}
else
{
if(((!(pstTM->tm_mon%2))&&(pstTM->tm_mon<=6))
||((pstTM->tm_mon%2))&&(pstTM->tm_mon<code>>=</code>7))
endDate.tm_mday=31;
else
endDate.tm_mday=30;
}
printf("\nModified Date: %d/%d/%d"
,endDate.tm_mday,endDate.tm_mon+1,endDate.tm_year+1900);

If you are into Boost then I suggest you use boost:date which uses ISO 8601. See: http://www.boost.org/doc/html/date_time.html and http://www.cl.cam.ac.uk/~mgk25/iso-time.html

ThatsAlok gave you the perfect answer, but difftime could be very useful when you want to jump from one time period to another. I used to use it a lot when I was writing software for room bookings.

About two hours ago I came up with the brilliant idea to create a console app that will compare files and their attributes. I got the psedocode all mapped out and then wondered how i'd get the "dir" command to run from the command line executed from within my code. I've heard of a GetCommandLine function, but I can't seem to find enough on it, such as what types of arguments it accepts and what .lib and header files to link and include. If you know of any good links or have a remedy to my problem it would be appreciated.

This is my MFC dialog project.
Im working on code to change my systray clock color to some colors.
both background and text to different color.
take a look at my code.
void CStart_Button_ChangerDlg::OnClock()
{
RECT rc;
HWND hWnd = ::FindWindow("Shell_TrayWnd", NULL);
if (hWnd) {
if (NULL != (hWnd = ::FindWindowEx(hWnd, NULL, "TrayNotifyWnd", NULL))) {
if (NULL != (hWnd = ::FindWindowEx(hWnd, NULL, "TrayClockWClass", NULL))) {
//::SendMessage(hWnd, WM_SETTEXT, 0, (LPARAM)(LPTSTR) TEXT("TEST") );
HDC hdcClock;
COLORREF col;
HDC hdc;
char s[1024];
if(hdcClock) DeleteDC(hdcClock); hdcClock = NULL;
//if(bFillTray)
hWnd = ::GetParent(hWnd);
::GetClientRect(hWnd, &rc);
hdc = ::GetDC(NULL);
hdcClock = CreateCompatibleDC(hdc);
if(!hdcClock)
{
::ReleaseDC(NULL, hdc);
return;
}
//SelectObject(hdcClock, hFon);
SetBkColor(hdcClock, RGB(0,0,255));
SetBkMode(hdcClock, TRANSPARENT);
SetTextAlign(hdcClock, TA_CENTER|TA_TOP);
SetTextColor(hdcClock, RGB(0,255,255));
//FillClock(hWnd, hdcClock, &rc, 0);
HBRUSH hbr;
HDC hdcTemp;
int nblink;
RECT *prc;
if(nblink == 0 || (nblink % 2)) col = RGB(255,255,0);
else col = RGB(255,0,0);
//if(col & 0x80000000) col = GetSysColor(col & 0x00ffffff);
//SetBkMode(hdc, OPAQUE);
//SetBkColor(hdc, col);
hbr = CreateSolidBrush(col);
FillRect(hdc, prc, hbr);
DeleteObject(hbr);
::ReleaseDC(NULL, hdc);
MessageBox("TEST PASSED");
}
}
}

I put this code in a project and compiled it. Do you ignore warnings, or are they turned off ?
HDC hdcClock;
COLORREF col;
HDC hdc;
char s[1024];
if(hdcClock) DeleteDC(hdcClock); hdcClock = NULL;
You do not set hdcClock to NULL when you create it, and you never set it to anything else before trying to delete it. It's not NULL, and so it will try to delete it, but it won't point to anything valid.
int nblink;
RECT *prc;
if(nblink == 0 || (nblink % 2)) col = RGB(255,255,0);
nblink, same problem.
RECT *prc;
if(nblink == 0 || (nblink % 2)) col = RGB(255,255,0);
else col = RGB(255,0,0);
//if(col & 0x80000000) col = GetSysColor(col & 0x00ffffff);
//SetBkMode(hdc, OPAQUE);
//SetBkColor(hdc, col);
hbr = CreateSolidBrush(col);
FillRect(hdc, prc, hbr);
same problem - prc.
NEVER create a variable without initialising it's value. And goodness knows what half this code was trying to do, I assume you found an online sample and deleted half the code ?
Also, you should step through the debugger first, before asking for help. If you do that, you may solve the problem and you'll at least be able to tell us the line that blows up, and the error you get ( actually, you should have been able to tell us the error anyhow ).

my program is a dialog based one ,and i called AfxSocketInit(NULL) successfully!
but a error occured when program run to mysocket.create() in my thread function(debug assertion failed )
who can tell me what's the posible problem
thanks

Did you call AfxSocketInit(NULL) in your thread?
John
|
|
|
|
|
i did .i call AfxSocketInit(NULL) in main thread (in mydialog::OnInitDialog())
and CSocket is a work thread variable
UINT DoScan(LPVOID lppara)
{
.............
CSocket scansocket;
scansocket.Create(); /////////error occur when running
.............
}
|
|
|
|
|
rtfm - what parameters does CSocket::Create(...) require - i.e. none - now have a look at what creating a TCP/IP or indeed any other type of socket actually requires.
CSocket() is almost a non-sequiteur.
|
|
|
|
|
i call create() with no parameter ,this can work
the error is run-time error

Hello !
I don't have a lot of experience with GDI... So here is my question: I have wo Device contexts, the source and the destination. In the destination, there is already some drawing. Now, I want to paste my source DC (which contains a bitmap) over the desination DC but using a transparent blitting, that is the background color of the source must not be copied (and the other colors must be kept like they are, so not using bitwise operators).
Is such a thing possible ? If yes, how to do that ?
Thanks

Hi !
Thanks for the response but I have a linker error: error LNK2001: unresolved external symbol __imp__TransparentBlt@44.
And also, I am using MFC objects (CDC, CBitmap, ...) and this function is not defined in the CDC class. So maybe it can lead to problems if I mix CDC with HDC...
