its disable the page on OnInit of Propertysheet,
i want to enable/disable the page 3 with corresponding flag value of page 1.
now what can i do for this.

You can call EnablePage() from someplace else.

How to create Interface in c++? sample code pls?
|
|
|
|
|
There's no real interfaces in C++. However, a class with only pure virtual methods and no variable members is generally considered as an interface.

Is there a common way to handle such situation?
SomeObject* objects;
omp parallel for
for (i = 0; i < N; i++) {
int res = RunFunction(objects[i]);
if (res)
return res;
}
Once RunFunction failed stop processing and notify application

I'm no expert on openMP stuff...
can't you just break ? or simply change the loop value so that next iteration will not continue ?
int res;
SomeObject* objects;
omp parallel for
for (i = 0; i < N; i++) {
res = RunFunction(objects[i]);
if (res)
i = N;
}
return res;
Max.
Watched code never compiles.

break and return are no allowed.
I'm looking for the common practices and patterns in that scenario to not to envent something uncommon.

I'm no OpenMP expert, but isn't this an example of an algorithm that can't be paralleled as it is written. Imagine two threads, so it runs (0,1), then (2,3), but what if the return value of RunFunction(object[2]) says that the loop should stop, we have probably already executed RunFunction(object[3]).
It is not easy to come up with a way that stops a parallel loop with the same result as stopping a sequential loop.

it needs to prevent further processing in case of the single error even the next some other parallel returned correctly

That's why you want to do it, now you have to find a way to tell the compiler how to do it in one of the standard ways that it knows how to parallelise. Currently you are telling it that if RunFunction(object[n]) is false then it must not execute RunFunction(object[n+1]), and I don't think any compiler will know how to parallelise that.

the return value of your code corresponds to the logical OR of all those RunFunction invocations. If RunFunction() has no side-effects, you could use a global flag, and even abort all threads once a true value is encountered. If there are side-effects, your code is strictly sequential and cannot be parallellized; at best you could split RunFunction() in a first half without side-effects (that part can be run in parallel), and a second half that produces the side-effects (that part needs to be executed in strict sequence).

Is there some API to get list of all sockets opened in my process (opened by 3rd party module) and get some usage statistics? (at least last data send/receive timestamp to detect active connections).
Thank you.

Hello everybody,
I have a big understanding problem.
If I write those 2 lines
InvalidateRect(CRect(0,10,0,10));
GetUpdateRect(testrect);
Then "testrect" is empty. Shouldn't it get the values of my InvalidateRect?
Big thanks for any help

In fact, your rectangle is empty: CRect constructor accepts, as parameters, rectangle's {left,top, right, bottom}. See CRect constructor at MSDN.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi all,
i m using access database with odbc connection.
here in table i m using a Memo data type.
when i save value upto 255 char in this field its working fine but when i put more than 255 its generate problems.
its gives such type of error.
Mfc internal error: unable to load error string from resource
and generate CDBException at memory location 0x0885fb9c..
please help me for this.
i cant understand what can i do.
thanks in advance.

Access memo fields only support 255 characters maximum.

but i think memo field support more than 255 char.

Happily, what you think has no retrospective effect on the design of the Jet database engine.
It's theoretically possible to store more than 255 bytes in a memo field but there are lots of circumstances in which Access will truncate it to 255 bytes anyway. It treats memo fields like other text fields which have a limit of 255 characters.

ok now please tell me what can i use for more than 255 char.
|
|
|
|

Use an OLE Object field; it's really just for large blobs of binary data.
