In your handler for the cancel button, you should set a flag (or an event) that can be read in the worker thread that tells it you have cancelled.
Inside the thread, have it finish whatever it's doing and simply allow itself to exit after all necessary cleanup. Just before it exits, it can set another flag (or event) to signify that it is exiting the thread
Back in the main thread, wait for the signal from the thread that it is exiting, then you can safely let the main thread die (by calling your EndDialog).
Hope that helps.

thanks in advance

The other way around: link the flash file in a HTML page. Then Open the HTML page in your Dialog (again using IE activex ). This time your IE is gonna use the Flash Activex control.

How to associate a scrollbar with image
|
|
|
|
|
u want to scroll the image by scrollbar, don't u?
if yes and u use a dialog for image, just add 2 scrollbar beside the image area, when user clicks scrollbar, you "scroll" your image.
there are many ways to scroll an image, popular way is to display (i.e. BitBlt() or StrechBlt()) different part of the image according to scroll-position.
u should disable WM_ERASEBKGND message for better performance (no flash).

Given a HCURSOR handle, how can one tell if it is an animated cursor (loaded from an .ani file or RT_ANICURSOR resource) or not?

i'm a novice with a working c++ dialog program using VISUAL C++ IDE (version 6) that asks the user for path to a file which i process. How do i get a tree view of 'my computer' folders/files just like 'windows explorer details view' so i can select a range of files to process, one at a time?

MFC? Use CFileDialog or else use GetOpenFileName(). Be sure to include OFN_ALLOWMULTISELECT as one of the flags and make sure that OPENFILENAME::nMaxFile and OPENFILENAME::lpstrFile are set up correctly.

I think there is a file dialog control you can use. you can use that to make your life easier. I,m a newbie too but im using C# at the moment. ^_^

Hello!
I use an ActiveX component, that have function, that creates new object and returns LPDISPATCH pointer. In MSDN i'm read that IDispatch::Invoke provides access to properties and methods exposed by an object. But there is so many parameters, strange structs, etc... Can somebody explain me that or give URL with guid for dummies or give sample?

hey all
CryptAcquireContext(hCryptProv, NULL, NULL, PROV_RSA_FULL, 0)
The above function fails one computer out the hundreds we have tried on. Does anyone know of a reason why getting the default provider would fail on a particular computer.
Thanks for any insight

CryptAcquireContext
If the function succeeds, the function returns nonzero (TRUE).
If the function fails, it returns zero (FALSE). For extended error information, call GetLastError.
Also:
CryptAcquireContext() use and troubleshooting

That will fail if you've never used the CryptoAPI on the machine (or you've cleared out the key store). If the last error is NTE_BAD_KEYSET, call CryptAcquireContext() again with the CRYPT_NEWKEYSET flag.

I have used these operators numerous times without any problems at all. Until today that is.
char *bin;
int size = rec.comment[x].size();
bin = new char[size];
strcpy(bin,rec.comment[x].c_str() );
blob.setBinary((unsigned char*)bin, strlen(bin) );
sprintf(tmp,"update data set data=%% where student_id=%i and exam=%i;",
rec.student_id,
x );
buf.format(tmp,blob.getEncoded() );
db.execDML(buf);
delete bin;
Maybe I am doing something wrong, but all works well until it comes to delete bin. The program crashes with an error I have never seen before "DAMAGE: after normal block(#9160)".
Could somebody please point out what I may be doing wrong and what is the meaning of this error.
Thankyou.

In debug builds, new allocates more memory than requested and fills it with a certain byte pattern. When deleted, it checks to see if this byte pattern is still there, if not, you've written past the memory that you've requested. In other words, you didn't request enough memory and written past your buffer.
I think
bin = new char[size];
should be
bin = new char[size + 1];
to take into account the terminating null.
