Ubuntu Linux

Sat, 09 Jun 2012 09:17:33 -0700

Charlemagne wrote a new blog post in their blog.

My very first encounter with computers was with the Apple II, and a good way to use it was to know BASIC (PCs were called microcomputers then). That was way back in 1982. Later Microsoft was used specifically with DOS. I don't recall the exact dates but later I used MS Windows. All of these were machines used in the institutions I studied and worked in. The very first computer in the house was bought by my brother and it had Win95 and later Win98 was installed. We occasionally installed some other versions (Me and 2000) but it always gravitated to Win98. My dual boot desktop has WinXP in it.

In late 2002, I decided to try Debian GNU/Linux (kernel 2.2.20) mainly because Windows was very expensive, and also because Linux was nice and free. You only pay for the plastic (CD) and delivery. At that time, I had a hard time and I didn't even recommend it to others. You have to read a lot of documentation, but the more important side-effect was that I appreciated the inner workings of a computer. It also demanded that I use text mode more often (console) than GUIs. After a year or so, I backslid to using Windows again although my PC was dual-boot (can be booted with Windows or Linux). With some emails I received from a classmate of mine (UPCM '91), I decided to again dabble in Linux.

Using Google, I searched: "best linux distribution". The results were unequivocal. Ubuntu always popped up. So I went to its website and ordered Live CDs, and I was surprised that they were given for free, including the stamps! I then installed Ubuntu 6.06 (dual boot with WinXP), nicknamed Dapper Drake. It worked perfectly well: everything you can do with Windows, you can do in Ubuntu Linux. And everything is so easy.

The desktop was GNOME, which some say looks like a Mac (I don't know if this is true because I never owned a Mac).

A newer version of the OS becomes available every six months. Try Ubuntu; if you have only 1 PC, do a dual boot (disc has to be partitioned or sliced if only 1 HD is present).

There are many other free OS's out there... it's ultimately your choice.

problem with getprocaddress in service

Wed, 23 Mar 2011 02:27:11 -0700

vv40in posted a new message on the Windows programming forum.

Hello!
For example, i have a little function in dll:
void dll_func(){
char buf[32];
char* p = "qwerty";
strcpy(buf,p);
// or
GetLastError();
}

I call GetProcAddress("dll_func") and call got function.
If it happened in nonservice application, then dll_func works OK.
But if service calls dll_func, then it get access violation in strcpy.
In service debug window I see that [p = "qwerty";] - is unreadable pointer.
The same if dll_func contains only GetLastError() call - it get access violation.
I suspect that dll data segment was loaded incorrectly or did not loaded at all when dll was loaded fom service.
Anybody, could you help me!

I read around a few places to gain some understanding. The Windows Forms Textbox has a BackgroundImage property that you cannot set in the properties windows but will show up in the Intellisense. This property does not appear to draw anything, and anyone who has tried to draw one or make the backcolor Transparent says that once you type text in it will remove the Backimage/Transparency (and you cannot set it to transparent in the Windows Form Designer property box).

That said, every solution out there appears to be creating your own Subclass of Textbox that draws the image properly and is moderate to advanced code.

If you want to do something like that, here's suggestion on where to start:

Writing a new Windows service in assembler

Wed, 23 Dec 2009 16:08:11 -0700

deros68 posted a new message on the Assembly Code Share forum.

I have written some "MSGINA" notification packages in assembler but never written a program designed to be a Windows service.

32BIT XP/W7 is the target OS

W7 & Vista will no longer use the GINA DLL notification packages but
XP/W7/Vista all will use the SCM notification method which is why I need to learn what unique requirements a Windows "service" requires.

1. If it is a service that runs without ending - till shutdown - how do I make the service "sleep" or not consume resources ? while waiting to be notified of the 2 events I want to react to ?

2. I will want to register it to receive "wts_session_logon" and wts_session_unlock" events and then simply write an event log entry.

No desktop - no message boxes - no UI whatsoever.

Simple - right ?

Does anyone have sample ASSEMBLER code that I copy/model after ?

thanks

I see... I never use SetMapMode - I do all world transformations in my code if needed. I have seen some problems caused by non-English Windows (Korean in my case), but these issues were in .NET Framework. If this is for work - you could try calling Microsoft for support, but this call may be awfully expensive.

Also, MSDN specifies that this function is supported starting from Win2K, so if you are running on Win9x or Millenium - this may cause the issue.

when does delete[] actually free memory?

ColacX posted a new message on the Beginner C/C++ forum.

hi there i've got the following code to test on, you can try it on your computer aswell

int a=0;
char* array = new char[1000];
int b=0;
delete[] array;
int c=0;

ive placed breakpoints on all rows and steps my way through during debugmode
in taskmanager in windows i look at how much memory my application is using and after it excecuted row 2 the memoryusage increases but after it excectued row 4 the memoryusage doesnt decrease. its as if delete[] had no effect

however if i increase the size of the array to 1000000 the memoryusage does decrease and its as if delete[] is doing what its supposed to.

i can imagine that therse some sort windows memory usage optimization algorithm lying in the background causing this problem.
and the problem is that there's no way to test for small memory leaks if theres no change in the memoryusage reading.

my question is when does the "small" memory get deleted by the OS? this might be a hard question and possibly i posted this in the wrong category but this is a problem i have when i program in C++
