What actually is your problem? You want your program to perform different actions depending on presence of some command-line argument? Or rather you're asking about the function which tells if current user has administrative rights?

The first one, to perform different actions depending on command-line arguments.
Thanks.

The command line parameters can be used in the InitInstance() of your application. The command line is stored in m_lpCmdLine which is a char array. If you pass your parameter with a slash (ie. /MYPARM) they will be considered flags. If you don't include the slash the first
parameter will be considered to be the file you want to open. You can turn off that behavior my setting:
cmdIndo.mShellCommand = CCommandLineInfo::FileNew;
but why not just include the slash?
*NOTE you can test your command line parameter in the developer studio!
see the PROJECT - SETTINGS - DEBUG(tab)

How can i store 2 longs in a single variable. Similare to storing 2 shorts in a long with the MAKELONG macro. Can i do this with Long64?
Thanks
|

I don't think that will work because that stores it in a structure. I need it to be in one variable.

use an unsigned __int64, something like:
unsigned __int64 i64 = (unsigned long)longOne * ((unsigned long)-1) + longTwo;
ie.. the high 4 bytes are your first long and the low four are your 2nd long.
-c
All you have to do is tell the people they are being attacked, and denounce the opposition for lack of patriotism and exposing the country to danger.

How do i get the two longs back out of the unsigned__int64?
|
|
|
|
|
longOne = i64 / (unsigned long)-1;
longTwo = i64 - (longOne * (unsigned long)-1);
or something similar

You may use __int64 if you want to play with shifting bits. But why can't you use a structure?

A structure would solve the issue would it not?
#pragma pack(1)
typedef struct two_longs_dont_make_a_right
{
long one;
long erone;
} two_longs;
? Why in 'one' variable?

I need to save an Array of 2 shorts and long to a text file. I just figured it would be easier to save them in one variable that to seperate them with commas or something like that.

Why not use a structure in combination with a union, like so:
typedef struct tagTwoLongs
{
union
{
struct
{
long Long1;
long Long2;
};
__int64 OneVariable;
};
}TwoLongs;
Now you can refer to the two longs separately, via Long1 and Long2, or together, via OneVariable.

Make sure that the pack pragma is 4 or less for the union
technique to work. You might want to ensure this by temporarily
specifying the packing alignment:
<br />
#pragma pack(push,4)<br />
typedef struct tagTwoLongs<br />
{<br />
union<br />
{<br />
struct<br />
{<br />
long Long1;<br />
long Long2;<br />
};<br />
__int64 OneVariable;<br />
};<br />
}TwoLongs;<br />
#pragma pack(pop)
P.S. Is there a way to get a compile time
assertion that sizeof(long)==4?

Good call on the packing. I forgot about that.

Yeah, in winnt.h, there's a macro called C_ASSERT. Here's it's definition, and the comment that describes it:
#define C_ASSERT(e) typedef char __C_ASSERT__[(e)?1:-1]

ooh, nice. thanks. I've been wanting that ability
for a long time. I see they just sorta kludged
one up there. (neg index error.  )
Too bad this wasn't added to the language.

thanks, that works for me.

You mean the Win32 LARGE_INTEGER structure defined in WinNT.h

I only replied to him an idea and a simple definition. I suppose I could have used (and would have used) LARGE_INTEGER as my example, but I didn't think of it at the time.

I need a sample project - how to handle with data (store/edit/delete) in any format - but without any additional actions (registering in ODBC, etc.) I want to have redistributable application, wich are need juct unpack, and have to work with data.
thank tou.

Can I put both of these on the same machine? Any known problems or conflicts?
thanks

There have been a couple people here on CP that seems to be running both concurrently with no problems. I haven't tried it myself though.

Thank you. I just called MS and they said theres no problem....so I shall be brave and give it a try.
Appreciate your help,

Rather yes. I'm using both IDEs for few months and everything works fine. I think that it will be better if you install VS6 before VS7.
greetings

Great! Now if I click on a vS6 dsw, what program will be launched? VS6? Or do I have to first start VS6, then load the VS6 project into it?
Appreciate your help,
