Till the last day I belived that the global variables gets initialized automatically. But last day while debugging, I found out that the application start from the WinMainCRTStartup() function. And then stepping through that function, I came accross a function like this.
<br />
_initterm( __xc_a, __xc_z );
Then I understood that it is inside this function the global variables get initialized. That means the gloabl variable are explicity been initialized.
Can any one tell me whats this __xc_a and __xc_z variables are? And how the _initterm is doing the initialization?

It looks like __xc_a and __xc_z are arrays of function pointers - pointing to initialization
functions.
_initterm() loops through calling each function in __xc_a ... ?
It's in the runtime source code - see
crt0dat.c for _initterm()
cinitexe.c for __xc_a and __xc_z
crtexe.c for the xxxCRTStartup functions

if you run this code what happens?
<br />
class CMyFont : public CFont<br />
{<br />
DECLARE_DYNAMIC(CMyFont)<br />
<br />
public:<br />
CMyFont(); <br />
virtual ~CMyFont();<br />
};<br />
...<br />
...<br />
IMPLEMENT_DYNAMIC(CMyFont, CFont)<br />
CMyFont::CMyFont()<br />
{<br />
}<br />
CMyFont::~CMyFont()<br />
{<br />
<br />
}<br />
<br />
CMyFont font;<br />
font.CreateFont(...);<br />
GetDlgItem(1)->SetFont(&font);<br />

Friends,
Whenever we double-click a folder, a window gets open showing the contents of that folder.
I want to programtically open the window to show the contents of certain folder. How can i do so ?

Did you see ShellExecute?
ShellExecute(NULL,"open","explorer.exe","C:\\Program Files",NULL,SW_SHOW );
The above statement would open the C:\Program Files folder in the explorer view.
Somethings seem HARD to do, until we know how to do them.

First of all, you fellows really need an ASM forum in this place, so I won't have to ask all of my ASM questions in here. I do tie in most of my ASM code into C++ anyway, but its just disorganized to post it this way. I've been a member for over 3 years now and no ASM board? What's up with that? Other than that, it is a wonderfully great site ...
Anyway, on to my question. I need to :
1] print out the value in the AX register
2] I prefer to do it using int 10h, service 13h
[write string with attributes]
3] I need to be able to use the basic 16 colors
4] I need to be able to print it onto the screen
at any row and column that I wish
5] I can only use BIOS interrupts, so that means
10h for video, not 21h, since DOS will not be
loaded yet.
In summary, I need to display conventional memory size, and that means using int 12h. However the memory size is returned in AX, and I have no idea how to print that. I have googled things to death, and all I can come up with is 100s of sites telling me that it is returned in AX [duh ...] but how in the #$@% do I get to see AX ??!?
If I do not get that, then I get a bunch of hoo-hah about that awful NASM and such.
Apologies for all the griping, please help ...
Any ASM and / or C/C++ programmers feel free to
contact me via Y! messenger @ digitalmythology
or via e-mail @ digitalmythology@yahoo.com ...
Thanks in advance to all ...

The memory is returned in AX, so why not do a mov to move the memory size from AX to a variable of your choice?
pusha
int 12h
mov ax, My_variable
popa
You may be right
I may be crazy

i'm really a beginner here, so hopefully somebody can help me. i'm currently doing a dialog application. i need to add a "box" to show a vector( a graphic image of binary '1' or '0' that looks like square wave) inside it. The vector can taken from a file( that consist just '1' or '0') and i need to draw the vector(square wave where '1' is showing high and '0' is showing low amplitude). For starter, may i know how to create the "box"? Which function do you recommend me to use? Later the i also need to be able to zoom in/out to view the vector in the "box".
Thanks.

Can you be more specific about box?
|
|
|
|

Your description is not really clear... It looks like you need to draw a chart with a square wave into it. Am I right ?
If yes, you can take a look at my article here[^], maybe you can use it for your purpose ? It also support zooming.
If this is not the case, then you'll probably need to create your own custom control that contains the functionalities your are looking for.

actually i need to do a dialog based application for a IC tester(hardware). In this application, it will send some vector(series of '1' and '0' ) to the IC tester(harware) and then after the testing it will return back a result vector(series of '1' and '0' ) to the computer. Therefore, in the dialog, it will hv a button to start the testing. Once the button is pressed, the testing will begin and later in the dialog, it should display the input vector and also the output vector( which looks like a square wave to represent 1 or 0). The data for the vector can be taken from a file saved in text format.
The problem now is that how do i display the vector in my dialog box? Should i create and list box or picture to display the graph in the dialog? Also, are there anybody who knows how to draw a square wave by getting the data from a file( the file contains a series of 1 and 0, and if 1, the wave amplitude is high and if 0 it will show low).
Thanks in advance.

I can't make any more controlls...  no more buttons, listboxes.. no even static text..
If I take something away, "delete one of the objects", Then I can 1 more on... But then it's maxed out again and won't make any more. My program is a big dialog with about 400 objects on it... Is there something mabey that has a max setting.
I need to put on about 12 more objects into my dialog... Anyone got any ideas?

The resource editor does have a limit and you hit it. To add more controls you can always add them dynamically at run time using the Create functions.
|
|

|

Ok.. thanks.. to bad I can't just up the limit... Oh well..
I think I'll just go through all my static text objects and code them in.. That should free up bunches...
Thanks for the info...

Can you explain why you use of 400 objects,please?
