Hello,
I want to receive data after an AcceptEx() call. A brief overview:
1. I listen on a port and receive data with the buffer I've passed to AcceptEx().
2. When there is incoming data I process the data and send a return packet.
3. Now I wan't to receive data from the same connection again. I tried to use WSARecv() on the socket, but everytime I use WSARecv() I get an error with the error code 10014 (The system detected an invalid pointer address in attempting to use a pointer argument in a call). When I create a new socket with the socket(), bind(), listen() accept() procedure and pass it to the WSARecv() function I have no problem in calling WSARecv(), but I wan't to receive data from the socket on which I sent data. Can I use AcceptEx(), send() and then WSARecv() in this order??? How would you do this?
-----------------
Thank you for your attention,

I solved the problem, but I got a new problem. 
I'm able to send the return packet and I'm able to call WSARecv() on the socket, but I always receive the data, I sent. What's this???

hi
this is my first mail in this forum
i am using sdk for making a dll
now the problem is when i do not use any function of the given sdk and make a dll and then when i call a dll through my client vb application
the vb do the thing which i intend to do...
now when i use any function in the same dll(i have included the lib correctly) and compile and after compiling and when i try to run my client vb application,it throws an error saying run time error 53
file not found......
so my question is some special code is to be written when i use a dll inside my dll
i have to use the dll provided with the sdk for firing important function to use the card for which the sdk is present...
thanks

As an experiment, instead of loading the inner DLL and using inside the outer DLL, load it from the executable. Does it load okay?

Try checking the dependencies of your dll (try Depends.exe). You may have included the lib and compiled it, but the compiled dll might not be able to find the win dll containing the sdk functions which you used.

Hi everybody,
I'm trying to show an icon in one of the status bar's panes. The status bar is the CStatusBarCtrl and the problem is that I can only show 32x32 icons in the pane. When I load a 16x16 icon and call SetIcon() the icon on the statusbar becomes stretched to 32x32 in size, thus loses visibility of the most parts because the statusbar itself is about 18 or 19 pixels high. The workaround I've found is to create a 32x32 icon and place my 16x16 icon in the middle of that space and everything's fine. What am I doing wrong? Or is it that the 32x32 icons are the only ones one can display in a status bar pane? Any help would be greatly appreciated...
P.S: The icons that I'm using are for the WindowsXP platform and thus 32bit icons, 24 bit colour and 8 bit transparency, maybe that's a problem?

When a 16x16 gets stretched to 32x32 it's usually caused by calling LoadIcon() instead of LoadImage(), or using incorrect size parameters in LoadImage().

LoadImage() worked, thank you very much. I thought I tried LoadImage() without success before, but then I must have given incorrect parameters to it. And I didn't know that LoadIcon() stretches the bitmap to system metrics, thanks again.

Hi all,
Bit of a problem with CBitmap's LoadBitmap() function. If I make a bitmap a resource and do
BitmapObj.LoadBitmap(IDB_MYBITMAP);
The image is loaded fine, but if I do
BitmapObj.LoadBitmap("MyBitmap.bmp");
it returns 0 (failed). I've tried moving the location of the file around the local directory (debug, res, etc.) but no luck.
What do I need to do?
Obseve everything, remember more...

You can't load a bitmap file like that. To load a bitmap image from a file, use LoadImage():
HBITMAP hbm = (HBITMAP)LoadImage(NULL, "MyBitmap.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE); Hope this helps,

Okay, but there is a function LoadBitmap() that takes an LPCTSTR string of the name of the bitmap. How does one use it?

It loads a bitmap from a resource. If you look at the MFC source code, you'll find that the one that takes a UINT actually calls the one that takes a LPCTSTR to do the work.
All resources are loaded via strings. The UINTs have to be coerced into looking like strings so that Windows can load them.

yes sorry 
In fact i'm working with CHtmlView, and i want to know if it is possible to get all pixels state of web page from memory (RAM), i don't want to use GetPixel or....
I hope you understand
PS : excuse for bad english

I assume you are trying to dynamically change the HTMLView window (the Internet Explorer activeX object you drop onto a dialog in Visual Studio's editor), am I right?
Look at how you set the pixels (width and height) and maybe attach a global variable to it, and getting the address of the variable and use it that way...
I don't really know, usually I stick to variables and don't bother getting it from RAM in the way I think you want.

You probably can't. I assume the HTML view simply stores the HTML data which it renders as it needs to. It wouldn't store the individual pixel states.
If you want to get an "image" in a device context, you can try getting the HTML view to print itself. Send it a WM_PRINTCLIENT message with the wParam holding the handle of the device context to print into. Using MFC:
CWnd *pWndHTML;
CDC dc;
pwndHTML->SendMessage(WM_PRINTCLIENT, (WPARAM)dc.GetSafeHdc(), PRF_ERASEBKGND | PRF_CLIENT);
Keep in mind that this will only get the visible part of the view, not the whole document (unless it fits completely in the window).
Hope this helps,
Ryan

Thx for you answer !
I thought to this solution but i can't get all pixel state od the page only those there are display. So for me it is a problem

What do you need to get the pixel state for? There may be another way to solve your problem (without getting the pixel state).

Hi,
I am trying to make a dll for the images in my project. In the dll's project I add the resources (bitmaps) and I have functions to return HICONs, HBITMAPs, etc.
But I can't create any image resources in my dll.
In my resource.h I have
#define IDB_02 5001
but when I do
CBitmap dd;
BOOL ret = dd.LoadBitmap(IDB_02));
"ret" is false. Do I have to include something else in a dll to make it work with images?
Thanks

Before you call this, call AfxSetResourceHandle() to set the location of the resource, remembering to save the old one using AfxGetResourceHandle()
HINSTANCE hOldRes = AfxGetResourceHandle();
AfxSetResourceHandle(hinstDLL);
CBitmap dd;
BOOL ret = dd.LoadBitmap(IDB_02);
AfxSetResourceHandle(hOldRes); Hope this helps,
Ryan

I performed format function by calling the following function in shell32.dll:
(* dl_SHFormatDrive)(hWnd,cDrive-'A',SHFMT_ID_DEFAULT, bQuickFormat?:SHFMT_OPT_FULL);
My project can pop up a format dialog to format the floppy disk.
Now I want to hide the format dialog and let my floppy disk be formated automatically, in addition, I want to know the real-time value of ProgressBar's position. How can I handle this problem?
Please help me!
Thank you!
