But what I had done was to dial up directly into the DB Server from the PC client. and from either side, I can ping successfully to each other.
SO there is no firewall between the PC client and The DB Server.
Any suggestion?

Thanks a lots.
The problem was caused by some OS modules corrupted in Win 2k.
I changed to another SQL server on a third machine, now I can access via SQL Query Analyzer and my program.

I would like to know how to create an instance of a program run within the window of the calling program (like the start or web tab in the older versions of Kazaa when it would open an instance of Microsoft Word for example to view a document) could someone please help me.

Look into COM and Embedded Document stuff. (I've just exhausted my knowledge on the subject...)

I'm brand new to C++ and I have to figure this out really fast. I'm almost completely lost so I could use all the help I can get. Thanks in advance. This is what I need to do:
Write a program that allows you to add two time durations expressed in hours, minutes and seconds. Your program should prompt the user to enter these fields for both times and the display the result including a day field. Here’s an example of what your output might look like:
First time duration
Enter hours: 12
Enter minutes: 23
Enter seconds: 32
Second time duration
Enter hours: 13
Enter minutes: 26
Enter seconds: 47
Total time is 1 day and 01:50:19.
|
|
|
|
|
double difftime(
time_t timer1,
time_t timer0
);
defined in time.h
|
|
|
|
|
And....?
What is your doubt, exactly?

If you expressed each field as a ratio of that part of a day, you'd have something like:
(12/24) + (23/1440) + (32/86400) =
0.5 + 0.015972 + 0.0003703 = 0.5163425926 (a little more than half a day) Do the same for the second duration yields 0.5602662037. The sum of those is 1.0766087963, which is 1 day, 1 hour, 50 minutes, and 19 seconds.
Or, you could add the fields individually, like:
s3 = s1 + s2
if s3 >= 60
s3 = 0
m1 = m1 + 1
end
m3 = m1 + m2
if m3 >= 60
m3 = 0
h1 = h1 + 1
end
h3 = h1 + h2
if h3 >= 24
h3 = 0
d3 = 1
end
print d3+" days,"+h3+" hours,"+m3+" minutes,"+s3+" seconds"

Hi all!
I have to do an enumerated type but I don't know how is it.
If my variable is "color" and it may have the value red, green, yellow, blue or pink, how would it be written?
Thank you in advance 
|
|
|
|
|
enum enCOLOR
{
enRED,
enGREEN,
enBLUE,
enPINK,
}
main()
{
enum enCOLOR mycolor;
mycolor = enGREEN;
....
switch(mycolor)
{
case enRED:
....
case enGREEN:
...
}
}

Does anyone remember the Win32 APIs to poke version info into an .exe? (The opposite of GetFileVersionInfo())

I dont know why its required, if anyone can change it from outside, then integrity of the versioning is lost. Version no should be changed during the build time only.
|
|
|
|
|
I wouldn't change post-build either;
However, I'm fairly sure that versioninfo is a resource, so you need the UpdateResource call. Note, however, that it is not supported on 9x or ME.
I'm sure there's an article on it hereabouts...

Thanks, Steve! I too am hestitant to change it post-build, and have come up with a pre-build alternative hack to burn the version into the .rc.

However much of a hack it feels, it will inevitably be easier than post-build.

Hi all, I am a total newb when it comes to program, I am currently in the process of writing my 3rd simple program, and I am having a whole bunch of trouble..becuase I am trying to teach myself, and I am lost trying to do this with online tutorials and whatnot
Alright this is my problem i found...I was given a file from a website....(studenttests.dat) It looked like this...
It gives the students name and his 3 tests scores then his average..
Smith Bill 85 75 74
Jones Ann 100 70 80
Walker Thomas 30 90 92
I have to be able to input the file into the program, Be able to calculate a certain students average by giving their name. and the program has to input the first 3 tests scores then average them...For some reason I cannot get the file into the program, I have tried from the A: drive and the C: drive, both to no avail...any help you experts out there could give a rookie like me would be GREAT...this is what I have so far..i know its very simple but like I said...Im a newb, ...this is the coding I have so far...but i am lost
<br />
#include <iostream><br />
#include <string><br />
#include <fstream><br />
#include <iomanip><br />
<br />
using namespace std;<br />
<br />
int main ()<br />
{<br />
<br />
float lastn1,firstn1, t1,t2,t3, lastn2, firstn2, t21,t22,t23,lastn3, firstn3<br />
,t31,t32,t33, avg1,avg2,avg3;<br />
<br />
ifstream inFile;<br />
inFile.open("C:\\studenttests.dat");<br />
inFile >> lastn1 >> firstn1 >> t1 >> t2 >> t3 >> lastn2 >> firstn2 >> t21 >> <br />
t22 >> t23 >> lastn3 >> firstn3 >> t31 >> t32 >> t33;<br />
<br />
<br />
if (! inFile)<br />
{<br />
cout << "Cant find file joe...." << endl;<br />
return 0;<br />
}<br />
<br />
avg1 = (t1+t2+t3)/3;<br />
avg2 = (t21+t22+t23)/3;<br />
avg3 = (t31+t32+t33)/3;<br />
<br />
cout << setprecision(2);<br />
cout << " S T U D E N T G R A D E R E P O R T"; <br />
cout << endl << endl;<br />
cout << "STUDENT TEST TEST TEST FINAL";<br />
cout << endl;<br />
cout << " NAME ONE TWO THREE AVG" << endl;<br />
cout << endl;<br />
cout << setw(3) << avg1;<br />
cout << "lastn1", "firstn1";<br />
cout << avg1, avg2, avg3;<br />
<br />
return 0;<br />
<br />
}<br />
And this is what it SHOULD look like...
S T U D E N T G R A D E R E P O R T
STUDENT TEST TEST TEST FINAL
NAME ONE TWO THREE AVG
BILL SMITH 85 75 74 78.0
ANN JONES 100 70 80 83.3
THOMAS WALKER 30 90 92 70.7
AVERAGE 71.7 78.3 82.0 73.3

This problem looks like a very familiar homework assignment that I was once given in college.
Could you be a little bit more specific than ".. cannot get the file into the program". Are you receiving an error message, etc..
Also you might want to take a closer look at:
<code>
inFile >> lastn1 >> firstn1 >> t1 >> t2 >> t3 >> lastn2 >> firstn2 >> t21 >>
t22 >> t23 >> lastn3 >> firstn3 >> t31 >> t32 >> t33;
</code>
If you're to read in last name, first name and then three test scores why are you trying to read the first and last name into a float?
Hope this information helps!

instead it should be

if (! inFile)
{
cout << "Cant find file joe...." << endl;
return 0;
}
inFile >> lastn1 >> firstn1 >> t1 >> t2 >> t3 >> lastn2 >> firstn2 >> t21 >>
t22 >> t23 >> lastn3 >> firstn3 >> t31 >> t32 >> t33;
why are you reading the name and the last name in float???
read it in string.

i tried to add win32 project to mfc project
all is well till the last thing that would not compile. i get error:
error C2664: 'CreateThread' : cannot convert parameter 3 from 'unsigned long (void *)' to 'unsigned long (__stdcall *)(void *)'
None of the functions with this name in scope match the target type
anybody?
thanks,
cheers

ummmmm calling conventions? name mangling?
read msdn for those subjects

add __stdcall before the thread function.

I have now:
in a header file:
DWORD WINAPI WorkerThread (LPVOID WorkContext);
...
in function definition:
DWORD WINAPI CMcastMFCNoSockDlg::WorkerThread (LPVOID WorkContext)
...
in main win:
HANDLE ThreadHandle;
....
calling function:
ThreadHandle = CreateThread (NULL,0,(__stdcall) WorkerThread,NULL,0,&ThreadId);
it now complains about:
syntax error : '__stdcall'
Please, one more shot.
Thanks,
|

Like this
In the class
static DWORD WINAPI WorkerThread(
LPVOID WorkContext);
Then in the defination:
DWORD WINAPI CMcastMFCNoSockDlg::WorkerThread (LPVOID WorkContext)
Then in your calling function
ThreadHandle = CreateThread (NULL,0,WorkerThread,NULL,0,&ThreadId);

Strange - got your email "
From: vglmco (vladimir.gershman@lmco.com)
this is not a class:
DWORD WINAPI WorkerThread(
LPVOID WorkContext);
does it matter?
I still get an error.
Thanks,
cheers
"
But no post.
Not a class???? In your previous post you say:
in function definition:
DWORD WINAPI CMcastMFCNoSockDlg::WorkerThread (LPVOID WorkContext)
That looks to me like the WorkerThread function belongs to the CMcastMFCNoSockDlg class?
Either:
Declare WorkerThread as a global function out side any class as DWORD WINAPI WorkerThread(LPVOID lpVoid) and also define it outside the class, or declare it inside the class as a static method with the same signature.
