And use it like :-

sharing CArrays

Ok I have a private member variable CArray containing a structure of data. I have a worker thread working with it. It finishes and the thread is terminated.

Then I try calling a non-threaded function in the same class and try to access the array it returns a -1. Why can't it be accessed even when locked?

I've made sure that its unlocked after its unneeded in the threads.

The GetSize was. I fixed this by making a global class variable and accessing the arrays through this.

Create SDI with formView, copy your dialog, change formView to use it.

Here is my dilemma with status bars...

I'm trying to run OnTimer routines that update GPS coordinates on a cStatus bar pane
...whats actually happening is i see a flicker of text in the wnd_pane and then it gets wiped away

...the strange thing is that when i click on the menu buttons the GPS text pane is always visible and there is no flicker.

how can i get the main frame to behave the same way so i can constantly see the GPS text ................real time??

i tried implemeting the timer update of the statusbar within the view rather than the main frame... but the result is the same.... what am i missing??

Unload a DLL?

I know this sounds far-fatched... but is there any way to force the OS to unload a DLL without exiting the program itself? I am working with a 3rd party library, which apparently has some global data in it that is initialized when it is loaded. I, however, need to re-initialize this data at a certain point in my program, and would like to do it without having to physically exit the whole program and restart-- the thought came to mind that maybe i could just force an unload/reload on the DLL in some manner.

Thanks for any ideas,

Array of numbers from C++ to VB

Anton A. Loukine2-May-03 10:19

Hi:

I have figured out how to pass data from VB to C++, but I am having troubles with sending arrays back to VB.

Suppose my C++ DLL created an array of integers and I have a pointer to this array that I pass back to the VB application along with the number of elements.

Now, how do I handle it on the VB side?
Do I have to allocate a buffer before I make the call, and let the C++ populate this buffer?
Or can I allocate the buffer in the C++ code?
What if I don't know the size of the buffer beforehand?

If I just have the pointer and the number of elements, what would be a VB equivalent to do something like this:

for( int n = 0; n < nTotal; n++ )
{
dValue = *( ( double * )cPointer );
cPointer += sizeof( double );
}

Thanks a lot.

Use a SAFEARRAY.

Re: Array of numbers from C++ to VB

Anton A. Loukine2-May-03 10:30

I though about using SAFEARRAY, but it seems to add too much of (maybe) unnecessary overhead. Can you think of any other options?

I have a feeling that CopyMemory would have to be involved somehow

Maybe because there is more code to write, the header of a SAFEARRAY contains more information than required. It may not be the case, but I would like to consider more than 1 option.

Also, when a safearray is passed from C++ to VB, what is actually passed (i.e., pointer only, the header + pointer to data)?

CDHtmlDialog in vs .net 2003

Has anyone else seen this:
I have a single HTML dialog that is called by a DLL. When the dialog box is displayed, there's the standard TODO:, OK, and Cancel buttons underneath the conrols I have added/changed. However, when you edit the dialog resource, they are not there. I could not find anything in the .rc, .rc2, or resource.h My assumption is that they are getting added from a library or something. Any ideas?
