Did you try handling CTLCOLOR_STATIC inside your form view's OnCtlColor function?

For colored statics, you may find useful info in these articles:
* Using colors in CEdit and CStatic[^]
* Colored/Blinking Controls and Dialogs with any Font[^]

Using message reflection is the way to do so (ON_WM_CTLCOLOR_REFLECT)
You shouldn't create your brush each time OnCtlColor is called. You could initialized it only once and then pass its handle. Moreover, for each CreateSolidBrush should there be a DeleteObject, or your system will run low for GDI objects.

calling the right API interface?

Really, just entering "IP" into MSDN revealed that IPHelper might be what you want.
From there you can start to follow the references.

Hi,

I try to compile this code:

std::sort(actionlist.begin(), actionlist.end(), compareActionlist);<br />

actionlist is a vector.
But i get this error:
error C2039: 'sort' : is not a member of 'std'

I have tried to put using namespace std in the top, but that doesn't help.

Can someone help me? Thanks!

Threading related question

Hi,

Consider a thread function:

MyThreadFunc()
{
 // do something

        <code> Sleep(50000);</code>

 // do something

    return;
}

As can be seen above that my thread blocks in the middle. What i want is that whenever user close my application, all the threads no matter what are they doing should first end gracefully but immediately. But suppose that my thread is stick on some blocking operation as shown in above code. How can i immediately cancel this blocking call and ask the thread to exit properly?? Infact i am using events after every next statements to check their status and exit my threads, but under such situations where the thread is stuck in a long blocking call my application waits like a hell. I want to immediately finish this thread. How ???

Example: In MSN messenger there is an option of cancel sign in. If we select this option then the connecting thread "immediately" stops working. Of course this thread calls various blocking Winsock calls especially for domain resolving, but it ends immediately.

See WaitForSingleObject in the MSDN and set the event when you want the Thread to stop.

So what kind of blocking functions are you calling?

If you're using Winsock you can create a non-blocking socket and check to see if a connection has been made or a message has been sent/received using the select function. If you want, this select function can 1) not block at all (not recommended) or 2)block for a set amount of time.

If you are using sockets I would loop through: telling the select function to block for an undetectable fraction of a second, check to see if the operation has completed, and repeat until the operation either completes, is cancelled, or is timed out.

My suggestion is to make it appear that the thread exits immediately even though it doesn't. In your MSN message example, how do you know the thread stops immediately? If a dialog box goes away, maybe it wasn't controlled by the blocked thread. After all, how does it respond to your click on "cancel sign in" if the thread is blocked?

Also, are you sure the MSN messenger thread is blocked? Maybe it made an asynchronous call and is processing messages until it gets a reply.

If you absolutely have to have the thread exit immediately, you can call TerminateThread, but read the docs about why it's a bad idea.

In addition to the obvious answers you'll get, I thought I'd add a little apparently-not-too-well-known-something.

Depending on what the thread is blocked by, what you request might actually not be possible. There are instances when a thread hangs in the kernel, making it effectively impossible to terminate the process (the only way to terminate such a process is power off or hardware reset).

Hi,

Anyone knows how to implement a class similar to RichEdit control (i.e. with text formattings) and the method we can get the mouse click on some words (or "links") in its content ?

multiple threaded dll??

xxhimanshu9-Feb-03 18:08

hi,
I got a dll file in which one of its function process time
is about 5 seconds.
When I do iteration, the process time becomes 5 seconds x
number of iterations which makes my application very slow.
I tried to create multiple threads in my application
but it didn't have effect because those thread will
share a single thread of the dll.
According to what I've read in MSDN, all windows application
share the same dll process in memory. So if many application
use it, its process becomes slow.

My question is, Is there a way to create multiple process
of the DLL in memory? So I can use different processes of
DLL for each iteration? any pointers or any article suggestions..please..thanks in advance

A solution could be to use two views in the frame, one for the data and one for the column header.

Is there any simple way to distribute Visual C++ 6.0 (work with DAO & MS Access 2000)

Hi,

After reading article at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvc60/html/redistribvc6.asp ... I am very surprise that we have to do a lot of steps to distribute a single Visual C++ application working with MS Access & DAO

Is there any simple way to include every thing in a single CD? Here are what I have:

a) An Visual C++ 6.0 application: Trial.exe
b) A Trial.mdb that is needed for the Trial.exe (MS Access2000)

What I need more to put in the package and install them in a PC that has Window98 (or later) without having MS Access & Visual C++?

I do know one thing, if I install in that PC ---> Visual C++ only with Access Database option ... it will work! How can I do a similiar task without installing Visual C++?

Thanks for any help
