In your project settings, add the file Glaux.lib to your "import" box of the link section.
Hope this helps. Happy programming!

I have written a C program to insert a row in SQL Server 2000 but it seems not to work.
#include<stdio.h>
#include<conio.h>
int main(void)
{
int number;
char fname[80], lname[80];
clrscr();
printf("Enter a number : ");
scanf("%d",&number);
printf("Enter your first name : ");
scanf("%s",fname);
printf("Enter your last name : ");
scanf("%s",lname);
execl sql include sqlca;
execl sql insert into Table1
values(number,",'",fname,"','",lname,"'");
getch();
return 0;
}

Could you explain what it is that does not work?

The error i recieve while compiling
Compiling ..\SOURCE\SQL.C
Error ..\SOURCE\SQL.C 15: Undefined symbol 'execl'
Error ..\SOURCE\SQL.C 15: Statement missing ;

Well I guess there is no such command in the C language!
|
|
|

I have taken the command from SQL The Complete Reference.

It looks like unix command line codes instead of C, but maybe that's just me

Harold (above) is correct, these are Unix commands, so unless you are compiling in a UNIX system they will not be recognised. What exactly does the SQL book say about this?

Dear friends...
I have some clarification on C++ basic
1. "Unsigned variable” this line is accepted in C++ With out specifying any data type like "unsigned int var" or "unsigned short var", how this will allocate memory space?
2. Here is my code ( i am using Visual C++ 6.0)
String mystring ="";
getline (cin, mystring);
cout <<mystring <<="" endl;
this="" getline="" method="" expects="" 2="" "enter"="" button="" actions="" why?
3.="" and="" the="" other="" clarification="" is=""
="" cin="">>mystring;
cout <

1. unsigned int will take the same amount of space as a signed integer; likewise unsigned short.
2. On my system the getline() call requires only one <Enter> key.
3. cin reads into 'mystring' until it sees a space. The remainder of the line is read in by the getline() call which, by default, reads until it sees the line delimiter.
See the string::getline[^] page in MSDN for further information.

1. Because C standard establishes the equivalence between 'unsigned' and 'unsigned int'. See the "ISO/IEC 9899" standard, available as PDF here [^], check out page 100.
2. Because you can get a line only when it is (newline) terminated.
3. That's wrong: the two statements
cin >> mystring;
and
getline(cin, mystring);
are equivalent.
3. Because space is one of the string terminators for the >> operator.

I have a program which generates GUID.Is there a chance that more than one thread spawned at the same time (< 1 millisec) in the same machine to have same GUID?.
Thanks,
Rane

There is no chance, unless GUID generation mechanism is broken, I guess.
Why don't you make a little test?

I don't think so. The GUIDs will be different.

I'm writing a MFC MDI app. which can interactively apply certain processes on an image. I'm trying to have a menu option that will make a copy of the current image so you can get back to a previous image state, or compare different processes on the same image. Of course, this can be done by saving the image to disk with a new name and loading it back, but it would be nicer to just be able to make a temp. copy of it at any stage of processing.
I don't want a new view of the current doc. because then any changes to the doc. would be passed to both views. When I tried it from the doc. side it replaces the current doc. and I haven't gotten it working from the view side either.
Any help would be appreciated.
Thanks,
D

You don't specify how you are holding the image data in your program. However, assuming it is some set of records, all you need to do is create a new set and copy the data from the existing set into it. You can, of course, design a set that keeps track of individual changes but that is a little more complicated.

I'm using the CImage class, part of MFC that comes with Vis. Studio 2008. basically what I'm trying to do is get MFC to make a new document w/o opening a file up - just blank, then I can copy the image to it.

It's some while since I have used MFC, but these are all just C++ classes so you should be able to adapt the base class to your own requirements. You can override the OnNewDocument() member function, or (I think) you can use the CDocument() constructor to create a new one.

Well,
you work with a document and a view. Let's say your document has a CBitmap and some other parameters to hold coordinates, colours and so on.
When you save to disc, you are probably using the serialize.
One way would be...
If you just want to have a copy of your data, without saving to a file, then the best option (if space and amount of data is not an issue) is doing a copy. For instance:
CBitmap_1 --> CBitmap_2
CPoint coordinates --> CPoint coordinates_2
and so on...
Of course, all classes you use must have a copy and assignment operators. If don't you won't be able to do what you want.
Another way would be...
Using the disc to hold a temp copy of your data, you can do it without calling the Save.. or Save as.. I mean, when you call the function you want to have the "Back" action, you make a parallel saving in disc, but the user don't get any prompt to give name or even notice it using the CFile and its set of functions.
For instance, I made a software to connect with a PLC and was able to read the actual values of a Step7 function, but to do that, the actual project in the software and the read function in the PLC must be equal. So I got a copy of the online function and made a translation of the project in the programm to compare them. The user didn't notice anything of that.
Regards.
