I had a similar problem when I had Norton Antivirus installed.
When VC tries to create the executable, Norton thinks a virus is writing to the hard drive, and stops the process. At least, that's what appeared to be happening... 
Get rid of Norton (if you have it) and see if it changes anything.
There are 10 kinds of people - those that get binary and those that don't.

I uninstalled Norton and everything is perfect now...
Thanks Miszou and all the others...

Hej,
Im using M$VC++6.0 and when i compile my application, VC will just get stuck during compiling or linking. Could someone help me on that?
My current solution is CTRL ALT SUPPR, and restart VC++, i guess there is something better...
Thanks,
Remy
PS: I have now this problem even with small projects.

Hi All,
I am hoping that there is someone out there who will understand my problem as there seems to be very little documentation avalible to read the values of the NDIS 5.1 compatible drivers. I would like to initiate a scan of the BSSID's in my network area. The documentaion tells me I need to use OID_802_11_BSSID_LIST_SCAN to force the wirelss nic to scan the area for access points. Unforetunately I haven't been able to guess how to call this feature. The code that I tried is the following
PNDISUIO_QUERY_OID pQueryOid = NULL;
pSetOid = (PNDISUIO_SET_OID)&QueryBuffer[0];
pSetOid->ptcDeviceName = _T("WLAGS461");
pSetOid->Oid = OID_802_11_BSSID_LIST_SCAN;
hr = DeviceIoControl(
m_hNdisUio,
IOCTL_NDISUIO_SET_OID_VALUE,
(LPVOID) pSetOid,
sizeof(PNDISUIO_SET_OID),
NULL,
0,
&dwBytesReturned,
NULL);
but it fails with error 0x57 (parameter not correct) and I don't know what to change.
I also have the following code that I have been using to get the aquired list (or the one already in the NIC database)
<code>
PNDISUIO_QUERY_OID pQueryOid = NULL;
pQueryOid = (PNDISUIO_QUERY_OID)&QueryBuffer[0];
pQueryOid->ptcDeviceName = _T("WLAGS461");
pQueryOid->Oid = OID_802_11_BSSID_LIST;
hr = DeviceIoControl(
m_hNdisUio,
IOCTL_NDISUIO_QUERY_OID_VALUE,
(LPVOID) pQueryOid,
0xFFF,
(LPVOID) pQueryOid,
0xFFF,
&dwBytesReturned,
NULL);
</code>
and it works fine. I get a list of access points.
Anyone have any suggestions?
Sincerly,
Clint Singer
P.S. I should mention that I am also working on Windows CE (although that shouldn't make a differance except for the ptcDeviceName) paramter.

I'm trying to display a bitmap on my window. Here's my code:
BITMAPINFO biBitmap = {0};
BITMAPINFOHEADER bihBitmap = {0};
bihBitmap.biSize = sizeof(BITMAPINFOHEADER);
bihBitmap.biWidth = 16;
bihBitmap.biHeight = 16;
bihBitmap.biPlanes = 1;
bihBitmap.biBitCount = 24;
bihBitmap.biCompression = BI_RGB;
bihBitmap.biSizeImage = 0;
bihBitmap.biClrUsed = 0;
bihBitmap.biClrImportant = 0;
biBitmap.bmiHeader = bihBitmap;
PAINTSTRUCT ps;
HDC hdc = BeginPaint(ghWnd, &ps);
HDC hdcMem = CreateCompatibleDC(NULL);
HBITMAP hbm = CreateDIBitmap(hdcMem, &bihBitmap, CBM_INIT, finalrgb, &biBitmap, NULL);
HBITMAP hbmT = (HBITMAP)SelectObject(hdcMem, (HBITMAP)hbm);
BitBlt(hdc,60,60,16,16,hdcMem,0,0,SRCCOPY);
SelectBitmap(hdcMem,hbmT);
DeleteDC(hdcMem);
EndPaint(ghWnd,&ps);
finalrgb is a pointer to an array of unsigned chars containing RGB values for a 16 by 16 pixels picture.
What am i doing wrong?
Thankyou!

I've always noticed that object ID's for my menu items show up in each class in ClassWizard (Visual Studio 6). So, for example, I've associated my menu resource with my view class. And that class is where I add all of the menu items' message handlers. But the menu items' object IDs also appear in my options dialog class (in ClassWizard).
Since my menu will never appear in this dialog box, my CDocument class, etc., is there a way that I can limit menu object IDs to show up only in the class which hosts the menu resource?
It's kind of annoying when I add a message handler for a menu item, then realize that I'm in the wrong class...

It is very iritating isn't it.
Another iritaion:
If you create a dialog based application then the about dialog class is defined in the same file as you main dialog and every time you bring up the Class Wizard from with in that module it automaticaly selcts that About class for modifying.
I am like you, at the very least I wish that once a handler has been assigned for an ID that it would no longer give me the option to add anoutehr one some where else (since the second one would not be call any way).

Hi.
I use the StretchBlt function to draw a image to my dialog, the StrechBlt is called alot, every 100 ms, but it seems like there is a memory leak, and I can't figure it out.
I just call this:
StretchBlt(GetDC(hwnd),0,0,200,200,TimesUp,0,0,0,0,SRCCOPY);
I have initilized my image in another call, which does not get called every time.
Anyone have any idea?
Thanks

HDC hDC = GetDC(hwnd);
StretchBlt(hDC,,0,0,200,200,TimesUp,0,0,0,0,SRCCOPY);
ReleaseDC(hwnd,hDC);

Hi,
I utilize Visual C++ 6.0 with MFC.
I have split the main window in two panes with a static splitter.
In my view OnDraw member function, I want to draw text in a pane and graphic in the second pane.
I have a code like this one to activate a pane:
pMainWnd->SetActiveView((CView*)pMainWnd->m_wndSplitter.GetPane(0, 0));
But I draw in both panes.
How can I draw in one pane only?
Do I have to utilize two views?
Thanks,
Claude

I haven't done what you are doing, but in an MDI app with splitters (see sig) each pane is a separate view and you draw into the required view.

You should be using two different view derived classes: 1) a text view and 2) a graphics view. It sounds like you are using the same view class for both panes so that when you modify the document and call UpdateAll() both panes show the same data.

:(Is it possible to access the screen image saved when the CS_SAVEBITS style is used. I do realise that the image may have been saved by the driver or it may be an image stored as a bitmap in memory. I am also aware that the image can become invalid at any time. I am trying to figure out how this mechinism works [to get insight into some incomplete ideas I have].

I did not realy believe I could but I had to ask. I looked thru "Windows Internals", "Programming Windows", some other books, and searched the www before posting.
Thanks just the same!
This is the first time some one actualy answered one of my more difficult post.

Just an idea I had about replacing it with my onwn bitmap bits. I was thinking that if I could get more control of the drawing on the Desktop window I might avoid creating a whole new window class just so I could provide a shadow for a dialogbox, just like menues have. I had already decided it would not work even if I could get to the bits. The shadow feature is not realy needed, but it would be nice to add that feature to dialogs derived from CDialog (in a simple manner).

Aha. Have you looked at code like Bruno Podetti's CNewMenu http://www.codeproject.com/menu/NewMenuXPStyle.asp[^] which adds a shadow. I'm using this in ED (see sig) and it works quite nicely. I think the shadow may have problems on older versions of Windows though. I'd need to check.

Yes. In fact I am using CNewMenu in the project that is also using the my CDialog derived base class. The problem is that I did not want to subclass and handle all the drawing my self. I wanted to allow a dialog to be drawn normaly including borders (style dependent) and then add a shadow to it.
I did have another idea that might work, but I do not like it. The idea would be to create a second sightly larger window that would cover the the dialog box then set its' drawing region such that only right and bottom of the window will be visable at the right and bottom of the dialog box and then draw the shadow in that region. That way know one will be over writing the shadow. Of cource then you have to keep moving (or sizing) the shadow window when ther user moves (or sizes) the dialog. There are other problems with this idea, but coming up with unique solutions to a problem is what makes programing enjoyable.

Don't like the second window idea at all. What about hooking the dialog instead of subclassing it. There is also this article: http://www.codeproject.com/menu/SkinMenu.asp[^]
But I don't really know if I like the idea of a drop shadow on my dialogs.;)

"But I don't really know if I like the idea of a drop shadow on my dialogs"
I created a CDialog derived base class that allows you to treat a dialog like a menu (more or less) with embeded controls. By using the class it is easy to create things like color picker drop downs with minamal effort. If you want I can email you the program (.exe) I was working on when I came up with the idea (it is now using shadows) so you can see for your self.
I am sure that hooking will work in this case (same problem as subclassing). The problem is that the shadow must be drawn inside the window its' self so that it will not be over drawn by other windows. That requires that I: 1) enlarge the dialog window, 2) read the pixel data from the desktop, 3) stop the default drawing and erasing of background, and 4) draw the border (and background) my self. I may check into trying this later on, just to see what all is involved.
Even though I do not like the second window idea, I decided to try it and it worked [although there is a momentary flicker when the dialogs OnPaint() is called]. By making the desktop the parent of the second window, with style set to WS_VISABLE (ONLY), then using a modified version of CNemMenus' shadow draw code in its' OnPaint(). There was no requirement to specify any regions because it is under the dialog and the only visable part (even when draw alone) of the window is the part drawn as a shadow. Throw in a little code to handle move, size, and when to close and bingo it works. It does not even require that I read pixels directly from the desktop since until I draw the shadow the background of the window is the same as the desktop.
I still think the second window idea is the wrong approach to the problem, but it can be used with any modal dialog window and may be modifiable to work with any CWnd derived class).
Thanks for all your sugestions.
Trust in the code Luke. Yea right!
