C / C++ / MFC

Are you using MFC? If so, then the MFC database connectivity classes[^] will be useful.

If you're not using MFC, then the ATL database classes[^] may be useful.

Other alternative technologies are ODBC[^], ADO[^] or DAO[^]. They'll all be painful (to some degree) to use with raw C++.

How about reading about these api's from MSDN SQLHandle,SQLAllocHandle, SQLSetEnvAttr, SQLAllocHandle, SQLConnect, SQLAllocHandle, SQLExecDirec.

You need to google first, if you have "It's urgent please" mentioned in your question.

Apparently, you want him to read-up about SQLAllocHandle() thrice? Big Grin | :-D

I wanted him to read this function more than once. So after reading each API go back and read about SQLAllocHandle... Probably the OP may understand it's importance. Smile | :)

Just a typo, copy pasted the API name thrice

On another note, there's no harm in reading an API three times or more or until the point when it starts making some sense. $Shucks | :-\$

How to reduce .avi file size..

30-Mar-09 20:43

Visual C++ may refer to the Microsoft C++ compiler, or even the IDE. You can think of it as C++ on windows. MFC is a c++ framework written around Windows APIs to make life easier. Wikipedia has separete entries for Visual C++[^] and MFC[^]. Give them a read.

That would be a very good start if you are good at object oriented programming, specifically C++. (But legend says that you must start off with Win API and then move forward to MFC, not that it is a rule though)

Good luck with your learning. It must be fun. Smile | :)

How to get ordinal value of function programitically ?

AVI compression looks like a viable option? There are video compression libraries on the internet (some with source code and samples).

Dear All,
I have created a dll in vc and exported some function. How can get ordinal value from function name in vc? I searched on google but could not find the result which I was looking for.

Thanks
Manish

can somebody help me to solve this problem? Pls help me, as soon as possible. This is a numerical method question.

solve the following system:

2x1-x2=1
-xi+2xi+1=0, i=1,2,.....,n-2.
-xn-1+2xn=1.

Using a)thomas method,
b) Jacobi method,
c) SOR scheme (use w=1 (Gauss-Seidel), w=1.1, w=1.2, w=1.3, w=1.4, w=1.5).

Use intial approximation x^(0) e=10^-6. Limit the maximum number of iteration to N=500. Display the output in the following form:

Number of iteration for convergence:?

Solution:
x1=

x2=

.

x20=

Hi

If this is your problem:

   2x1-x2=1     ...................[1]
-xi+2xi+1=0, i=1,2,.....,n-2. .....[2]
-xn-1+2xn=1  ......................[3]

solution:

from [1] you get:

x(2)= 2*x(1)-1
from [3] you get:

x(n-1) = 2*x(n) -1

from [2] you get:

 n= ? : rem n value should be set

 for j=1 to 50
 rem  50 is max iterations set to.

 for i=1 to n-2
  if i=2 then
   x(2)= 2*x(1)-1
  end if

  x(i)= 2*x(i+1)

 next i
  x(n-1) = 2*x(n) -1
next j

Remark: I hope I understood your problem, since the solution
correctness depends on that too.
If your your problem is not stated correctly, that
belongs to you.
I hope that I helped, if you need more let me know.

system() parameter complications

Alright, I'm trying to have my program, which was writting in C++ using Dev-Cpp 4.9.9.2, open a separate program.
I know this can be achieved throw the use of system() but I can't seem to get it to work right, I'm currently using the command line:

system("c:\\Program Files\\Internet Explorer\\iexplorer.exe");

I get the error "'c:\Program' is not recognized as an internal or external command, operable program or batch file."

Re: system() parameter complications

30-Mar-09 20:18

It's just a command line, as passed to CMD, so put double quotes around the path as it contains spaces:
```
system("\"c:\\Program Files\\Internet Explorer\\iexplorer.exe\"");
```
Isn't it iexplore.exe, not iexplorer.exe?

Thanks again Stuart really appreciating all the help you're giving me. That one worked perfect on the first try. I didn't know anything about double quotes until a little bit before i posted this issue. I looked up other examples on google and when I tried it with the double quotes before it told me the same issue. But having just tested it with the line still saying iexplorer instead of iexplore it gave the error again, so it looks like that was my issue.. really need to stop doing this at 2 am..
