Hi,
Most of your code seems to be commented out, so it will not be executing.
Could you point us where exactly problem occurs, and what kind of error it is, please?
Regards

There is no error when code is simply
LRESULT CALLBACK CBTProc(
int code, // hook code
WPARAM wParam, // removal flag
LPARAM lParam // address of structure with message
)
{
if (code < 0) return CallNextHookEx(CBTSysHook, code, wParam, lParam);
if(code == HCBT_ACTIVATE)
{
HWND hWnd = (HWND) wParam;
TCHAR cWind[512], cClass[512];
GetWindowText( hWnd, cWind, 512);
GetClassName( hWnd, cClass, 512);
}
return 0;
}
An error occurs when I add DAO support, exactly when program is run
and I open Light Alloy, press 'play' and further press X - to close,
it happens error sound, my program goes on to work
, and nothing else is different with normal closing

I use CList instead of DAO, I mean I use back-write, here is it.
But except for my Program, which call CBT.dll, nothing is written.
I open the testHook table, and there is it
#1: myMonitor #32770
#2: myMonitor #32770
#3: myMonitor #32770
#4: myMonitor #32770
#5: myMonitor #32770
Why is it so? Is there any secret?

When it's commented it's all right,
When it's full open for compile an error occurs
when I close Light Alloy, while movie is being played,

I am creating a skinned window, which I want to be resizable. When I create the window I remove all the window styles in order to correctly display a bitmap
SetWindowLong(hWnd, GWL_STYLE, GetWindowLong(hWnd, GWL_STYLE)
& (~(WS_CAPTION | WS_BORDER | WS_SIZEBOX)));
I then handle the WM_NCHITTEST returing values for the new title bar, min/max buttons etc. I have also created a region around the edges of the bitmap within which the resizing should be possible. The problem is, after removing the WS_SIZEBOX style, DefWindowProc() no longer allows resizing of the window. Of course I can do it programatically using SetWindowPos() but this is a far cry from dragging the border. Is there any way I can use the WS_SIZEBOX style, without displaying the border?

Hi,
Currently you're using only client area of the window (that's why you removed caption/borders), did you try to use WM_NCPAINT instead of WM_PAINT?
In WM_NCPAINT you can erase/paint entire window area, discarding its default painting proc for caption and borders. This way you could probably save your sizing borders.
Best regards

I hava a programme that coulde transparence the window/dialog in 2000/XP, it use the SetLayeredWindowAttributes function to transparence window/dialog.But, the function coudle only transparence window. And i want transparence the client area in SDI/MDI. Who can tell i how to do it?

You can do it in a handler for WM_ERASEBKGND.
By just returning TRUE this will prevent any background from being drawn.
BOOL CMyMDIWnd::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}

Hi,
I have created a sdi in which the view is divided into three panes.Now i want to color the splitter bar,splitter box,borderetc.For that i have written a function like following in a class derived from CSplitterWnd.
void CMCSplitterWmd::OnDrawSplitter(CDC* pDC,ESplitType nType,const CRect& rect)
{
CBrush brush;
CBrush *ptrBrushOld;
if(pDC == NULL)
{
CSplitterWnd::OnDrawSplitter(pDC, nType, rect);
return;
}
switch(nType)
{
case splitBox:
{
VERIFY(brush.CreateSolidBrush(RGB(128, 255, 0)));
break;
}
case splitBar:
{
VERIFY(brush.CreateSolidBrush(RGB(128, 255, 0)));
break;
}
case splitIntersection:
case splitBorder:
{
CSplitterWnd::OnDrawSplitter(pDC, nType, rect);
return;
}
}
ptrBrushOld=pDC->SelectObject(&brush);
pDC->Rectangle(rect);
pDC->SelectObject(ptrBrushOld);
}
Now my doubt is ,where to call this function in mainframe class.Is this necessary to call this function in mainframe class.
Thanks

Hi,
I have an application that uses multiple threads in order to perform a calculation. When run on a multicore processor there does not seem to be any increase in speed. Is it a misconception to expect the operating system will split a multi threaded applications to different core's automatically?
Regards,
Ingo

Hi,
AFAIK, windows system doesn't split cores between different threads, but instead it split cores between processes. In order to assign specific core to a specific thread, you should use SetThreadAffinityMask. Before you set new affinity mask for thread, you should obtain current affinity mask for entire process (GetProcessAffinityMask), and of course, affinity mask of your thread can only be a subset of mask of your process.
In order to specify new affinity mask for your process, use SetProcessAffinityMask.
Before you change anything, try to read multiple MSDN documents about: Multiple Processors, Processes and Threads, etc...

Thanks for the reply. This seems to confirm my observations. I'll probably try OpenMP hoping they will do the windows specific stuff right.

I create a simple DialogBox with the "Designer"
Then i create the variables to the components and call the DialogBox like this:
MyDialog* dialog = new MyDialog(NULL);
dialog->DoModal();
delete dialog;
The window opens, but nothing is accessible, even i can't slide the window.
If i switch to another window for example IE, the DialogBox is still there in Top-Position
The Dialog is like frozen
Anyone an idea?
Thanks

I don't see anything wrong with your code. Can you just tell or post some code about how are you going with the creation of the dialog and why do you pass NULL in the constructor?
Somethings seem HARD to do, until we know how to do them.

normally i pass "this" in the constructor
I think i'll post my question to the forum of the Toolkit that i use.
It's propably a side effect
Thanks nevertheless

|

i don't see anything wrong either.
but why are you allocating the dialog on the heap ?
why no just doing this :
MyDialog dialog = MyDialog(NULL);
dialog.DoModal();
BTW, isn't your window "frozen-like" due to a huge process called by OnInitDialog() ?
if you have such treatments to do, you should consider delegate these by worker threads...

Hi,
I don't know if this or a similar question is already asked, the search function only gave a .jar-article, so I try to ask on my own.
In a project I have to compress and copy files to a remote computer which should work without any user interaction, and so I'm now asking for a way to do that.
The whole program should run under Windows XP, which can read ZIPs, but are there system libraries to generate ZIPs, or do I need special programs / libraries to zip them? Can I zip files under C++ or do I have to call standard programs nevertheless?
And regarding the transfer, is there an easy way to initiate a non-interactive ftp-transfer of the zip-file after zipping has finished? Can I use the ftp-Program included in windows giving special command line options or do I need a special ftp-library to transfer that file to the remote server?
I'm using MS Visual C++ 6.0 under Windows XP (SP2 installed), if this info is important...
Thanks in advance for your help

Hi,
I recommend you to look at this: 7-zip
It is 7-zip's LZMA SDK, and I think it should fit your needs.
