If you are going to be accessing num[5], you'll need to use:

int num[6];

That has no bearing on your problem however.

why 6 ?
If we say int num[5], it naturally has six elements right? 0,1,2,3,4,5.

so num[5] would point to 6th element. what's wrong here I dont understand. Confused | :confused:

NULL

Arrays in C are 0-based. By declaring int num[5], the largest index value you could access would be num[4].

If you are using ATL, and you have some DispID interface, the way to get arrays back into VB is typically to put them into a VARIANT array.

Typically, the VARIANT is of type VT_ARRAY and wraps a SAFEARRAY.

Hi

I have a doubt in VC++. My doubt is, is it possible to hook any function in any process or in other words can a DLL be injected into any process.

and finally

Is there anyway one can prevent others from injecting DLL into there process address space.

Thanks in advance

"any function" - how can you know a function name from a process on which you don't have control?

If you are talking about windows APIs, there is a nice article at CP try here

Hi there,

Could anyone tell me what would be the requirement to use Microsoft mappoint for real time use. like I pass latitude and longitude upon request to mappoint and I could see the location of the device that sends the lat and long on the map. I do not know what should be the interface between my application that sends the lat and long to mappoint to this.
Appreciates any suggestions.

Restoring Window - Help.

Hi all,

The thing is, lets say you have two windows open with the same name, for example:
- window1
- window1
and both of these windows are minimized, and you want to restore both of them.
The thing is I can do it for one window, but struggling with two of them.
This is what I have done so far:
WindowTitleName = "window1";
hWnd = ::FindWindow(NULL,WindowTitleName);
BringWindowToTop(hWnd);

How can I get the handle for the second window that has the same name??

Please someone help.

Mnay thanx in advance

Do both windows share the same class name?

How would I know that? What differences would exist between two windows that share the same name?

Sorry but I think they do have the same class names.....

Then you cannot use FindWindow() to uniquely identify one over the other.

Did you create the windows (e.g., CreateProcess(), ShellExecuteEx())?

No I didn't create the window, another application calls this dll and I check if the window is minimized and if it is I restore it. The application sends the dll a name that id'd the window name, and the rest of the problem I have already mentioned.

Do you have any advice / site / source?

Thanx for the response

Yes, just have the application send the DLL a window handle instead of a caption.

Hi,
Iam sending data to ComPort and using RS-232 cable Iam trying to receive the data at the other end.
I set the properties also(BaudRate,Stop Bits,Parity etc..)both at sender and receiver.

Sending End:
char dataToSend[100];
dataToSend = "asdfsdf ....";
result = WriteFile(handlePort,dataToSend,99,&length,NULL);

Receiving End:
char dataReceived[100];
result = ReadFile(handlePort,dataReceived,99,&length,NULL);
cout << "Data Received = " << dataReceived<
