Hello friends!
I wanna to display the baloon tooltip in my application.
But the problem is with the ShellApi.h header file which is not
having the defination of the szInfo and other constants like NIF_INFO.
I've tried the things like defining constants like
#define _WIN32_IE 0x0500
#define _WIN32_IE 0x0600
as suggested in some advises but this doesn't solve the problem.
Can anyone pls tell me what should be done exactly to achive this task?
Many Thanks in advance.

Using the res protocol to access an HTML inside the resources it works just fine with images but not with flash files. What am i doing wrong ?
<BODY background="HTML_RES/tile.gif"> ---> this works
but the following does not.
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0" WIDTH=300 HEIGHT=200 name="myMovie" id="myMovie"><br />
<EMBED src="HTML_RES/clock.swf" quality=high bgcolor=#FFFFFF WIDTH=576 HEIGHT=384 TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" NAME="myMovie" id="myMovie"><br />
</EMBED><br />
</OBJECT>
Does the Res:// protocol support flash objects inside resources?

Hello everybody,
i want to create a shortcut (.lnk) to a DOS application.
There are many samples at CodeProject, but i need to set the initial size to a specific value.
On a "exe".lnk the user has the possibility to set the window size for this kind of window or only
for this "session of the window"
But i like to set these values in C++, so that the user don't need to set this value on his own.
Big thanks

Make it yourself: an option at the command line (of the link) and proceed it.

The DOS Application behind it is made with a special "DOS-Window" component.
We try to set there'in some values to adapt it the window.
But it's hardly strange to change the intern values of the display.
But thanks anyway

i have a combo box which is of type int. i need to retreive the value that is there in the combo box. that is for example i have 2 values in a combo box. 100 and 200. now when i select 100 from the combo box the value has to send than the index. how can i do that?

With MFC, the simplest a way is binding the combo to an int a CString variable (use the Add Variable Wizard of VS) and then convert the latter to an int (for instance with _tstoi). You may also use the GetItemData/SetItemData pair to store (and retrieve) directly int values inside combo box items.
If you don't like MFC, the you should retrieve the item text and then convert it to int, i.e.
const INT SIZE=0x100;
TCHAR buffer[SIZE];
INT SelectedInt;
LRESULT sel = SendMessage(hCombo,CB_GETCURSEL,(WPARAM)0, (LPARAM)0);
if ( sel != CB_ERR)
{
INT n = SendMessage(hCombo,CB_GETLBTEXT,(WPARAM)0, (LPARAM) (LPTSTR) buffer);
if ( n != CB_ERR)
{
SelectedInt = _tstoi(buffer);
}
}
Please note, I used a 'quick way' of allocating a relatively large buffer (since your combo contains short strings); you can use CB_GETLBTEXTLEN message to know requested buffer size in advance.
BTW, you have also the option to associate the int values to the Item Data of the combo box and retrieve it, whenever needed, via CB_SETITEMDATA message (it is left as an exercise for the reader...  ).

i am using MFC. my requirement is simple. whenever i am trying to acess the variable i am getting the value as the index. i need to value from the combo box.

You're right, mapping the combo to an int variable make the latter containing the selected index value.
Hence you can either:
(1) Map the combo to a CString variable and the performing _tstoi on the variable.
(2) Getting a pointer (say pCombo) to your combo box class (you can either map a variable or call GetDlgItem) and then:
int nSel = pCombo->GetCurSel();
int nSelValue;
if (nSel != CB_ERR)
{
CString strValue;
pCombo->GetLBText(pCombo->GetCurSel(), strValue);
nSelValue = _tstoi(strValue);
}

is there any other way to get the value in the combo box. i am declaring the combo box variable as int. and this variable is used in some more files. so cant change the data type. it can be only int.

In fact, you can. Sometimes a bit refactoring effort it is worthy to do.
Anyway I don't insist on design policies, hence, supposing you int variable name is iCurSel (and your combo box ID is IDC_COMBO), you can do:
int iValue;
UpdateData();
if (iCurSel != CB_ERR)
{
CString strValue;
((CComboBox *) GetDlgItem(IDC_COMBO))->GetLBText(iCurSel, strValue);
iValue = _tstoi(strValue);
}

alright.. i have done it. now i have one more thing to do. i need to pass this value to another file. tried using static. but i dont know if i am doing it the right way. it has an error. i tried to declare the variable as
<br />
static int value <br />
in the .h file.
what is the procedure to do that?

I have problem to send a message to the server application using send() function using winsock.h. Im trying to send my MAC address information to the server. Firstly, i detect the MAC address at the client side using GetAdaptersInfo API. The problem is the MAC address is an unsigned character. The send() function could not send this type of message. The error would produce 'error C2664: 'send' : cannot convert parameter 2 from unsigned char [] to const char. I tried to convert the unsigned char to const char using casting but it is still the same. Maybe i did the casting wrong. How can i solve this? Is there any examples? Thanks

Maybe by posting what you did so that we can see ? Without code it's quite a challenge to tell where you are wrong.
Usually, a casting is sufficient.

Probably you have something similar to:
SOCKET mySocket;
IP_ADAPTER_INFO myIPAddrInfo;
hence you can do something like:
send( mySocket, (const char* )(myIPAddrInfo.Address), myIPAddrInfo.AddressLength, 0 );

Thanks Pallini. I think that should solve it. I altered the code and there are no more error. I didnt update the code on the receiver (server) side yet but i think it should not be a problem. If there are problems, i will get back to you guys again. Thanks alot guys.

I want to read the first byte of a buffer. Tried as follows.
char cRet_Ser_ID = *((char*)&InMsg[0]);
Is this ok, I mean is there any other way to do this.
I appreciate your help all the time...

If InMsg is a char array, then you can simply do:
char cRet_Ser_ID = InMsg[0];
If not, you can simply do this:
char cRet_Ser_ID = *((char*)InMsg);
InMsg is equivalent to &InMsg[0]
