May be it seems to you, while debugging it might completes.
Try this,
-TestFTP.bat-
ssh.exe -pw @
net start ftp
pause
and check whether WaitForSingleObject returns immediately.
And also, check your batch file executes correctly,
ShExecInfo.nShow = SW_SHOW; // you can change it later.
ssh.exe -pw @ // if ssh is not installed it returns error. similarly.

At one point in time, batch files were processed one line at a time, with an open and close each time. So technically, the batch file did complete, but there was no distinction between the first line completing vs. the whole thing being complete. One other thing to try is CreateProcess() instead of ShellExecuteEx().

You can use EnableWindow() to disable or enable those buttons.

You can also:
CWnd *pWnd = NULL;<br />
pWnd = GetDlgItem(IDCANCEL);<br />
if (pWnd)<br />
{<br />
pWnd->ShowWindow(SW_HIDE);<br />
}
It is easy to find out the other ID's from the other buttons...
You can use also : m_psh.dwFlags &= ~PSH_HASHELP; (in the property sheet).
And in each property page... :
m_ppSysSig.m_psp.dwFlags |= PSP_USETITLE;<br />
m_ppSysSig.m_psp.dwFlags &= ~PSP_HASHELP;<br />
m_ppSysSig.m_psp.pszTitle = "SYSSIG";<br />
AddPage(&m_ppSysSig);
Hope this helps...

Often programs compiled without errors don't behave as expected.

Try to reformulate the description of your problem since it isn't that clear.

Did you coded for this,
May be WS_EX_TRANSPARENT style set to the window.
May be WM_ERASEBKGND and / or WM_PAINT handled but not doing anything or not passing to default window procedure.

Hi all,
I have created a Directshow filter for video playback. It runs fine in GraphEdit or by double clicking the video file but when I select the thumbnail view for the video file in explorer, explorer crashes giving the ASSERT error
Executable: explorer.exe Pid 328 Tid fc8. Module myFilter.ax, 5 objects left active! At line 317 of C:\DXSDK\Samples\C++\DirectShow\BaseClasses\dllentry.cpp
Continue? (Cancel to debug)
Can anybody suggest how this bug can be removed?
Thanks in Advance.
Regards,
Tahir

Did you try to use your debugger ?

It occurs if you acquired any interface and not releasing it, when the filter is about to destruct. The interface acquired in your filter may be other filters which might acquired other interfaces and your assert message shows 5 interfaces not released.
I think you must be able to get this error in graphedit also, stress test for different scenarios, like pause the graph and close the graphedit, insert and remove filters, close graphedit while running graph. The thumbnail might be in different state which you never tried in graphedit.
log the reference count of the interfaces while you acquire and release and check whether it matches. for all your pins and filters override the
"STDMETHODIMP_(ULONG) NonDelegatingAddRef();"
"STDMETHODIMP_(ULONG) NonDelegatingRelease();" so that you can log easily.

Raj thanks for your reply.
I will look into it. I will try 'log the reference count ' thing and will come back with the results soon.

Below is the code snippet I wrote for displaying pixel values onto the screen in MFC. The pixel values are stored in buffer disp_frame. But nothing appears on screen. Could anyone debug this code.

int p=0,i=0,j=0,q=0;
// extern int disp_frame[50][144][176];
///////////////////////

BITMAPINFO bm;
RGBQUAD rgbarray[256];
bmi.biSize = sizeof(BITMAPINFOHEADER);
bmi.biWidth = 176;
bmi.biHeight = 144;
bmi.biPlanes = 1;
bmi.biBitCount = 8;
bmi.biCompression = BI_RGB;
bmi.biSizeImage = 0;
bmi.biXPelsPerMeter = 0;
bmi.biYPelsPerMeter = 0;
bmi.biClrUsed = 0;
bmi.biClrImportant = 0;
bm.bmiHeader = bmi;
for (int color_index = 0; color_index < 256; color_index++)
{
rgbarray[color_index].rgbBlue = i;
rgbarray[color_index].rgbGreen = i;
rgbarray[color_index].rgbRed = i;
rgbarray[color_index].rgbReserved = 0;
}
bm.bmiColors[1] = rgbarray[0];

CBitmap *pOldBitmap =MemDC.SelectObject(&MemBitmap);

Have a look at CreateDIBSection documentation [^]. It states the 5th parameter (a pointer to a pointer) is an [out] one. It means you have to pass the address of a pointer and, on return, that pointer will contain the address of the allocated DIB section buffer, then you have to change the bit values of such buffer, according to disp_frame values, before selecting it into device context.

ReleaseDC(pDC);
}
This was the piece of code which was posted previously. But the CreateDIBSection code
CreateDIBSection(MemDC,bm,DIB_RGB_COLORS,disp_frame,NULL,0); was having MemDC is a CDC type. But actually it should be HDC type. So I have rewritten the code as
HDC hDC;
hDC = CreateDC("DISPLAY",NULL,NULL,NULL);
HDC memDC = CreateCompatibleDC(hDC);
CreateDIBSection(hDC,bitmap,DIB_PAL_COLORS,ppbits,NULL,0);
HBITMAP memBM = CreateCompatibleBitmap(hDC,176,144);
SelectObject(memDC,memBM);
BitBlt(memDC,150,100,176,144,hDC,0,0,SRCCOPY);
But CreateDIBSection is creating exception. What could be the reason. Basically I could not get the difference between CDC and HDC. Could anyone give a clear solution to my problem. I am actually trying to display a grayscale image which exists as R=G=B values in memory.

Please surround code snippets with <pre> tags.
(1) What error message are you receiving?
(2) how did you define ppbits?

The error message was Unhandled exception in decoder.exe(GDI32.dll): 0xc0000005 : Access Violation
the declaration for ppbits was void **ppbits.
Once this CreateDIBSection works i thought of filling ppbits with pixel values. That's why that particular piece of code is not available

The above is wrong.
You have to declare a pointer to void, for instance
void * pbits;
and then pass the address of the pointer (i.e. &pbits) to CreateDIBSection:
CreateDIBSection(hDC,bitmap,DIB_PAL_COLORS, &pbits, NULL,0);

Hello evry body, how is it possible to flash the icon of a certain frame window, in order to capture the attention of the user and see the asynchrounous event that happened and which relates to the frame whose icon is highlighted ?
Thank you in advance.
