I am working on a assembler and linker (c++) for a specific microprocessor. I am using ELF format ( Executable and linking Format). I have very little documentation for the linker/assembler. I am having problem handling global variables in multiple obj file. i.e. the variable is defined in one file and can be used in other files. While assembler have scope of only one file how will the linker will know, in which file this global symbol is used.
I have searched many sites but found no relevant information. Would you please refer me to some article on ELF assembler\linker relaing to my problem.
Regards!

Does anybody know how to switch from the classical look to the advanced look, i mean for example in the buttons of the CWBButton class, how to disable and enable the ownerdraw using a single button, and the redraw all the buttons, for example a button that says change skin..., you're running the classic style, and when you click in that but, the other buttons are redrawed with the advanced style, all these examples are based on the CWBButton class.

I've read lots of information about JScript, but can't find something about JScript core, I'd like to know
how can I have jscript var list from VC.

Does anybody have an easy way to create the watermark bitmaps used in wizards (top right corner)? For example, I have a an icon, which I would like to respresent in the standard manner. I want to be able to do this at run time, rather than just editing a bitmap file and adding it as a resource. I assume I can just use BitBlt, but whenever I play with that, it never seems to do what I'm expecting!
Any suggestions and ideas welcome.

I think it is very simple to use GDI+ for this case,there are some article about it in CP

GDI+ available only in WinXP, but the standard solution talks about any of Windows systems

no,you can use GDI+ in win2000 too,it only need gdiplus.dll with installshield.
Check this

Hmm, thanx, I read it.. Not sure why I don't have those DLLs (I have Feb 2001 PSDK installed), so I'm just downloading a last version of Platform SDK now (Nov 2001). Also I found you can download the dlls separately from here
They said that win98/NT4 is minimum... but shame on people who are still using Win95, LOL
Thanx, I'll play with it

CPropertySheetEx class has a contructor that takes HBITMAP for watermark images in WIZARD97. Just use it, that's all. Read in MSDN about Wizard97 and CPropertySheetEx

Thanks for the info, but it doesn't help me in this case, I'm creating a 'wizard like' window, and not using property sheets, so I can't make use of the built in functionality.
What I want to do is take a colour icon, and then combine it with a background to make it just appear as a white outline, like the bitmaps shown in the top right corner of a standard wizard.
Thanks

Is there a kind of "open source explorer" (not for net, for files!)
like the Windows-Explorer or old-school filemanager?
I tried customizing the explorer eith shell extensions, but it didn't work! Any suggests?

Hi,
I am a Mechanical Engineering student.I am also very well versed incomputer programming.In fact ,I am encroaching towards Upper Intermediate Level.
After a lot of simulation programs I really want to work with real world models controlled by the computer.This is where I need help.
# I have good knowledge about 8085/8086 architecture.
# I also have sound knowledge of their instruction sets.
# I can create programs communicating through ports.
but I donot know where to begin.
? Should I use a microprocessor or a microcontroller
? How exactly should I program the mP or mC.
I know there are tools for this but the first question is still unanswered
I may be very good in software but not so conversant in hardware and stuff.So I have never connected things to my computer
So can any one of you help me get started?
Regards.
PS: let the developing language be C/C++/asm on PC

What are the size/power/cost/time constraints of the project? Usually the cheapest and fastest to construct approach is to use an ordinary PC (or just the motherboard) as the controller. Custom designed boards should be used only when absolutely necessary, or if you are planning for mass production. A SBC (single board computer) is the intermediate solution between a PC and full custom design. Same principle applies to software, use standard operating systems, compilers, libraries and other tools whenever possible.

Hello,
A few weeks ago, I read an article here on CP that included a class that added runtime resizing and moving of controls by use of the mouse (like the resource editor in VC). I can't find the article now and was wondering if anyone recalls this article and could point me to it.
Thanks!
Todd

Mazy,
Actually, that was not it. But I was able to find the correct one by searching for the base class that the article covered (CRectTracker). I couldn't remember the base class until I read that article.
The acticle I was after is http://www.codeproject.com/miscctrl/controltracker.asp
Thanks for the help as it pointed me in the right direction!

Hello,
I'd like to suggest someone to write an article about enumerating all open TCP/UDP ports with mapping them to the owning applications under Windows XP. Unfortunately, I don't have a time for it but I've written an example on C so you could use my code 
// portsenumxp.cpp (Windows XP)
//
// This example will show how you can enumerate
// all open TCP and UDP ports and map them to
// the owning application. It uses undocumented
// functions from iphlpapi.dll which were found
// by reversing netstat.exe.

hi,
I have been trying to find a source code that will generated a barcode from a membership ID number and also be able to read this barcode to call up the mmembers details from a database, does any body know were i could find something like this.
thanks for any possible info about this.

There are many different standards for barcodes. Do you want EAN-13? There are also many different ways to generate barcodes. One of the simplest would be to download (or make) a barcode font.
Anyway, here is a place to start:
http://www.makebarcode.com/stdorg/orgs.html
They have some general information to help you find the best solution for you.

I would like to request an article that explains how to send a file (binary) over a winsock tcp connection. (MFC)

Kuniva,
Please see the attached sample code of a Winsock client. With a little bit of improvisation and MFC socket programming knowledge you could easily change it to your needs.
/***************************************/
/* This is the sample code for a client that send and receives some data from a server.*/
DownloadFileFromInternet(CString strAddress)
{
char buff[1024];
int s;
struct sockaddr_in a;
struct hostent *h;
WSADATA wsaData;
int SERVER_PORT = 1223;// The server port to which the client will connect.
// This call initializes the Winsock.dll
WSAStartup(0x101, &wsaData);
// Initializing the sockaddr_in datastructer with all zeroes.
memset(&a,0,sizeof(a));
// First assume an Internet dotted form address e.g. 198.168.0.1
a.sin_family = AF_INET;
a.sin_port = htons(SERVER_PORT); // Connect to the server port
a.sin_addr.s_addr = inet_addr("127.0.0.1"); // Connect to the localhost. Replace this address with the IP address of the server.
/////////////////////////////////////////////
// You may use descriptive Internet (e.g. www.microsoft.com) instead of the dotted (e.g. 127.0.0.1) one.
h = gethostbyname("www.microsoft.com"); // change this address to the desired server's address.
if (h != NULL)
{
a.sin_addr.s_addr = ((LPIN_ADDR)h->h_addr)->s_addr;
}
else
{
AfxMessageBox("Cannot resolve hostname\n");
WSACleanup();
return FALSE;
}
// create the socket.
s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (s == 0)
{
AfxMessageBox("Cannot establish connection: ");
WSACleanup(); // Winsock.dll cleanup code
return FALSE;
}
// socket succesfully created, now we may connect to the server
if (connect(s, (struct sockaddr *)&a, sizeof(a)))
{
//Can not establish the connection to the server
WSACleanup();
return FALSE;
}
// Connection established with the server. Start receiving data from the server
int k=0;
k = recv(s, buff, 1024, 0);
if (k<0)
{
// An error occurred while trying to receive data
closesocket(s); // close the opened socket.
WSACleanup(); // clean up Winsock.dll
return FALSE;
}
buff[k] = '\0';
// we will NULL terminate the received data from the server.
// We will send "WA-ALIKUMASALAM" to the server.
k=0;
while (k < int(strlen("WA-ALIKUMASALAM")))
{ // keep sending until all the data is sent.
k = send(s,"WA-ALIKUMASALAM",strlen("WA-ALIKUMASALAM"),0);
}
// We are finished. Now its time to close the socket
closesocket(s);
return TRUE;
