I have a web-device that is running Windows CE 3.0 embedded. I've made a small webserver like application that allows me to type in it's IP address and view the webpages that I have set up on it.
I'm using a COM wrapper to wrap the low level C code. I instantiate the COM object with server side JavaScript (because there is no support for ASP), and perform the operations on the machine through the COM object.
Finally... Here's the problem: Whenever I call the functions to interact with the machine, the result I always get is 0 (S_OK). Even though I specify one of the parameters as [out, retval]. How do I call COM methods, that you usually pass a pointer to, from JavaScript and ASP, that do not have pointers?
Any help would be appreciated.
There's a fine line between confidence and arrogance.

Dunno about JavScript, but in ASP you can pass arguments ByRef. Same as in Client side VBScript

C++
BSTR bsOutRetval;
HRESULT hr = myCOMObj->SomeMethod(&bsOutRetval);
....
SysFreeString(bsOutRetval);
VB
Dim sOutRetval As String
sOutRetval = myCOMObj.SomeMethod();
If you don't grab it, I can explain more.

Hi,
How to capture monitor & display it on a Picture control using StretchBlt()
|
|
|
|
|
ALT-PrintScrn works wonderful!!!
Programmatically...I dunno...I imagine you could use GetDeskTopWindow() and use it's device context. However this ain't tried and true it's just a hunch.

CWindowDC wnd(NULL);
You now have a DC that contains the contents of your desktop.

hi,
How is it possible to change the color of a Button
|
|
|
|
|
Subclass teh button then you can handle the WM_CTLCOLORBTN message. In this message you will set the color of the brush that you want the button to use instead of the default color.
|
|
|
|
|
I done that method also...But I didn't get the color
|
|
|
|
|
You need to create a brush as a member object and return it from this function.

Only owner drawn buttons receive this message.

You should check out the WM_GETMINMAXINFO message in MSDN.

Given the window handle of a window in another app, how to get the processID and thread ID related to that Window? E.g. When we SPY++ a window, it'll show the processID and threadID under the window.
Thanks in advence,
Wally

ok let me see if I can articulate my problem. If I don't let me know.
I have a class called clientsocket that Is a derived from CAsyncSocket. I've overridden OnReceive to just put a AfxMessageBox on the screen when it is triggered.
ok heres the problem.
When I create the listening socket and accept the connection from inside a thread the OnReceive never triggers. I can send messages from the server to client but never get the Onreceive when sending something from the client to the server. The part that I can't figure out is that if I cut and paste the exact same code into a method that is called by a button on the main dialog window it works correctly. just not when I put the code in a thread... does this make sense? if not let me know and I can try to elaborate.

How do you know the routine isn't getting called? Have you set a breakpoint in the routine?
If you are just going by the lack of a message box, then maybe it is caused by trying to access windows in another thread and thus failing.
Instead of calling AfxMessageBox from a worker thread, just try ::MessageBox (NULL, "Made it", "Made it", MB_OK);
But these are all guesses.

I thought about that and added a break point put it doesn't break so I assume it never gets in there.
anybody that wants a copy of the code let me know and I can send it to them...its small...about 35k.
|
|
|
|

I just read somewhere that its bad to try to use a CSocket in a workerthread because of a lack of a message pump. could this possibly be my problem...theres nothing in there to handle the OnReceive?
