1)Try CListCtrl::DeleteItem
2)Try LVN_KEYDOWN Notification after adding notify_reflect
3)Try LVN_INSERTITEM Notification and keep a counter along with the LVN_DELETEITEM were you will decrement it and wen it becomes 8 disable it .

Wow, that is a big take. Jeffery Ritcher's book "Programming Applications with Microsoft Windows" is a must for system (non-GUI) developers. I don't think it has a free web version, though.

Best,

All are written by Jeffrey Richter and all are excellent. Trying to find reasonably priced copies, however, is a different story.

Hi together,

I need some help. I'm having some old VC6 code which works fine:

FILE* pipe = _popen("MyPipe", "r"); 
streambuf* buf = new stdiobuf(pipe);
istream in(buf);

However, I have to get it run in VS2005 where it doesn't compile. For example, the function stdiobuf() doesn't exist any more Mad | :mad:

As far as I understand it: The new template-based stream functions can't handle file descriptors any more.

So, here's my question: How can I get data from a pipe to an istream object? I need it this way, because the rest of the old code works on istreams.

Rose | [Rose]

Thank you very much for your help in advance!

Regards,
Marcus.

Imagine.. in the ATL implementation, we have a collection or an array, ie :

int num[5];
num[0]=100;..... [5]=500;

Now in my client, (i.e VB) , I need to access them like,
(Imagine collection is the property which points to the array I've mentioned above}

msgbox (MyComp.Collection[0])

It should popup 100.

A little bit urgent !

Frown | :(

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:

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?

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

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