{
DWORD dwState = 0;
DWORD dwSize = sizeof(DWORD);
BOOL fRet = FALSE;
if(InternetQueryOption(NULL, INTERNET_OPTION_CONNECTED_STATE, &dwState, &dwSize))
{
if(dwState & INTERNET_STATE_DISCONNECTED_BY_USER)
fRet = TRUE;
}
return fRet;
}
however, when i compile im getting the below linking error
error LNK2019: unresolved external symbol __imp__InternetQueryOptionA@16 referenced in function "int __cdecl Online(void)" (?Online@@YAHXZ)

But isn't it nice when someone finds their own answer and posts it, rather than just "It's OK, I fixed it"...

Hi
I want to be able to change the color of the border of the group box into 'green' for example.
How can i achieve this? By subclassing?
Greetings

I've just had a quick look, and WM_CLTSTATIC isn't going to help you with this. So you are
going to have to subclass and override WM_PAINT at least. There are plenty of "flat" controls
on CP which can give you a starting place.
Maybe a small article on your discoveries could come out of it?

Hi Iain
I've looked at some examples of CStatic controls being 'label fields'. Most of them are discussing the background color of text or control etc
But not how to color the border of the control.
Can you provide me with a good article about it or a code example?
Greetings
Jens

I load image file (.jgep) into picture control by using this code;
m_image.Load(m_SavePath);
m_CPicture.SetBitmap((HBITMAP)m_image);
This code is same with vb.net code:
picoriginal.Image = Image.FromFile(m_SavePath)
After that I need to cut a portion of the image and put it into another picture control with this code;
hdcDest = ::GetDC( CpThis->m_CpDest->GetSafeHwnd() );
hdcSrc = ::GetDC( CpThis->m_CpSource->GetSafeHwnd() );
::SelectObject( hdcSrc, CpThis->m_BackSurface.hBmp );
::StretchBlt(hdcDest,0,0,300,400,hdcSrc,pointlx,
pointly,cutwidth,cutheight,SRCCOPY);
::DeleteDC( hdcSrc );
::ReleaseDC( CpThis->m_CpDest->GetSafeHwnd(), hdcDest );
With this code the portion oh the image that have been cut is handle by hdcDest.
The problem is how I can save the cutting image into the new file(.jpeg)?
I can do it in vb. net by using this code;
picresult.Image.Save(Apath & "\result.jpg", Imaging.ImageFormat.Jpeg)
savebmap.Save(Apath & "\resultraw.raw")
How to translate this code into vc++ code?
Any idea to solve my problem, I apreciate it. Thanks.

GDI+ has functionality for this.

Thanks, I know it GDI+ can handle this but how to code it, I can get it, I have try so many times but cannot work. Now all the image data is in hdc but how to get from this into GDI+? Could you give some sample code, thanks.

I want to pass
MCSD exam 70-015,
(Visual C++ 6.0 distributed)
but official -sample questions - costs much for my country,
so does someone can tell me where is it possible
to find good free
sample questions ?
Other materials, referencies, good links,
"exam memories" ?
Interesting for precise relation:
does this exam is right qualifying people who passed it?
thanks you.

Hi everybody ! Little question:
I want to display a popup menu on the screen. This menu represent a list with selected channels (checked) and non-selected channels (unchecked). So, the user should be able to select/deselect a channel from the list. The problem is that these channels are dynamically created (so I don't know the number at design time).
So, how can I do this? (For example use just one single function to handle all events but how can I know wich item has been clicked??)
Any idea? Thanks

There's an example here of dynamically created popup menus.

Dear friends,
I’m beginner in Visual C++ 6.0 and I’m looking for advice and help.
I have English application which must be translated in other language like Rumanian, and Russian.
Can anybody advise from where I can get language classes for VC++6.0?
Thanks in advice,
Andrei Druta

Generally speaking, you'd do a few things;
(a) put translatable elements into your resources (menus, dialogs, strings)
(b) make separate language DLLs for each target
These have different names eg xxxEN.DLL (English), xxxES.DLL (Spanish), xxxIT.DLL (Italian), xxxDE.DLL (German), xxxFR.DLL (French), xxxRO.DLL (Rumanian), xxxRU.DLL (Russian) and they will contain translated resources
(b) Use language id to work out which DLL to use
(c) LoadLibrary the right DLL
(d) use AfxSetResourceHandle to specify which DLL to use
For number/date formats you can use GetLocaleInfo to retrieve country specific things like names of days/months etc.

Hi,
Can I use Unicode in my aplication for specific caracters?
If yes how can I include this in the string in my resource file like:
… code …
BEGIN
POPUP "&Fi"ş"ier"
BEGIN
MENUITEM "&Nou\tCtrl+N", ID_NEW
MENUITEM "&Deschide...\tCtrl+D", ID_OPEN
MENUITEM SEPARATOR
… Code …
Thanks.

You're on the right track with (b) but there is no need to have multiple files (unless you really need them). One of my company's products is used in over a dozen different countries. I create the English version, and translators from IBM create the others. In short, there is only one call to LoadLibrary(), and it's always for the same-named DLL.

Hi,
There is an excellent built in utility in VC++. here are the steps:
1) Create a uni-code file (use note-pad and save as uni-code for encoding option) save it with the extention *.mc
2) At the top of the file write the following code:
MessageIdTypedef=DWORD
LanguageNames=(
Russian=0x019:MSG00019
Hebrew=0x40d:MSG0040d
)
"Russian" and "Hebrew" are just for the example, search MSDN or developer sites (or use Visual Assist) to find out the code for the languages you need.
3) Each control that represents text (i.e a static text) must not be hard coded english, it should load its text dynamically using
m_pMyControl->SetWindowText(......) , m_pMyControl is the handler to the control.
Now i will explain how to fill the ...... in the SetWindowText
4) in the uni code file *.mc you will now add defines that will represent your desired text, add the following code in the *.mc file:
MessageId=
SymbolicName=IDSL_EDIT_BOX_CONTROL_MAIN_MESSAGE
Language=English
Your english text here
.
Language=Russian
bla bla in russian
.
Language=Hebrew
bla bla in hebrew
.
make sure you end the section with new line (press enter after the '.' at the end of the section otherwise it would compile correctly).
4) add the *.mc file to your project.
5) right click it and choose compile
6) notice after compilation a header file called Strings.h was generated.
7) now when ever you need the 'SetWindowText', make sure you have a
#include "Strings.h" and use the SetWindowText() method as follows:
USHORT uLang = 0x009; // English
// uLang = 0x019; // Russian
// uLang = 0x40d; // Hebrew
CString szMsg;
LPVOID lpMsgBuf;
DWORD n;
n = ::FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_HMODULE |
FORMAT_MESSAGE_IGNORE_INSERTS,
AfxGetInstanceHandle(),
uID,
MAKELANGID(uLang , SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0,
NULL);
szMsg = (LPCTSTR)lpMsgBuf;
m_pMyControl->SetWindowText(szMsg);
now the control will show the proper text in the desired language....
hope this helps ya

Hi all
I try to draw on dialog surfaces use CDC class this my snippet of code
..OnPaint(...){
...
COLORREF cr = 0x00009900;
CPaintDC dc(this);
COLORREF orig_col = dc.GetPixel(5,5);
RECT rc = {0,0,100,100};
dc.FillSolidRect(&rc,cr);
COLORREF dest_col = dc.GetPixel(5,5);
}
I have result of that routines
orig_col = 0x00c0c0c0
dest_col = 0x00009800
more distinctly in binary view:
orig_col = 0000.0000.1100.0000.1100.0000.1100.0000
dest_col = 0000.0000.0000.0000.1001.1000.0000.0000
Points here for my convinet.
WHy its so ???
Or how i can fill my dialog surfaces so what when i get pixel from this surface after this action ,color of this pixel will be equal filled color.I.e. i wish what routine
COLORREF dest_col = dc.GetPixel(5,5); retrieved me
0x009900 value.
I know what when i fill any surface ,original color of one mixed with filled color and this mixed mode controlling by SetROP2 function but i cant realize MSDN suggestions this complicated for me.Please anybody can give me link or simplcity recognized of this trouble.
Thanks.
Sorry for bad eanglish.

I'm doing some code parsing with the example code in chapter 5 (nonblocking server) in "Network programming for Windows 2ed".
What I'm thoughtful about is if FD_WRITE is always sent to the client socket after FD_READ?

The FD_WRITE you'd have to receive when the write operation is completed I assume.
also see Q186245 "FIX: FD_WRITE Reposted After Every Send"
there's some description about that

Aah, that could be true! But is FD_WRITE only sent in order to send pending data? I can't think of any other reason..
