Ok, so what's the problem? If g_hDllXtlPes is not NULL , I would expect GetLastError() to return 0. That means no error!

True but I have an error message "Unhandled exception in Appli.exe (XTLPES.DLL): 0xC0000005:Access Violation"...
And I haven't the result I would like to have which is the conversion of a file...

Set a breakpoint on the LoadLibrary() statement and step through each successive statement until the exception occurs. My guess is that you are calling the PESDEMUX_ProcessFile() function incorrectly or with invalid parameters.

Hi !
I'm using the std::vector class. Let's say my vector has 10 elements. I want to reach, with an iterator the fifth.
Here is what I'd like to do :
std::vector::iterator MyIt=MyVector.begin();
MyIt=MyIt+5;
MyResult=(*MyIt);
But it doesn't work. The only way I could make it work is to have a loop which will do five time ++MyIt !
Why can't I just to MyIt=MyIt+5 ? Any suggestions ?
Thanks !
Jerome

std::vector has random access iterators so you should be able to to do MYIt = MyIt + 5;
If you dont want to use a loop, you can use advance, which works for both random access and forward/reverse iterators.
#include < vector >
#include < iostream >
#include < algorithm >
using namespace std;
int main(int argc, char* argv[])
{
vector< int > v;
for (int i = 0;i<10;++i)
v.push_back(i);
vector< int >::iterator it = v.begin();
it = it + 5;
cout << *it << endl;
advance(it, 2);
cout << *it << endl;
return 0;
}

It works here ...
vector<int> MyVector;
for(int i = 0; i < 10; i++)
MyVector.push_back(i +1);
std::vector<int>::iterator MyIt = MyVector.begin();
MyIt=MyIt+5;
int MyResult = (*MyIt);
cout << MyResult << endl;
MyIt = MyIt + 3;
MyResult = (*MyIt);
cout << MyResult << endl;
Result screen:

Looks like it might just be a syntax error. Try changing
std::vector::iterator MyIt=MyVector.begin(); to
std::vector‹int›::iterator MyIt=MyVector.begin();
Notice the ‹int› after vector. Wow I never realized how much of a pain it was to put angle brackets in.

Hi all;
I am having some serious problems with CDialogBar. I cannot initialise the controls found on it. Its the tenth time that i am posting (posted as Krugger) this particular topic but i have not yet gone through it. Can somebody please help me. If you want a copy of the class implementation as well as a screenshot of the application i am developing to better understand, please mail me and i will send it to you.
Thank you for your help

how can i show the contents of "cout" used in C++ in Visual C++ 6 ?
|
|
|
|
|
If you meant that you wants to show some texts with cout with VC++6, here's the simple example.
#include <iostream>
using namespace std;
void main()
{
int iAge = 29;
cout << "Hello.\n" << "My age = " << iAge << endl;
}

Or you can try :
cout.flush()
~RaGE();

HELLO!
PLEASE HELP ME!
I'm new in C/C++ programming.
And i have a problem:
here is the code:
char ch=fgetc(filein);
char s[20]="";
Now what I want is to put in string s the value that is the ord(c).
Example:if c is 'a' then I want put in s value "97".
This part of my code is written in ANSI/C language.
How can I do this?
Thank you very much!
|
|
|
|
|
I assume that ord(c) should return you the ASCII value of char c (maybe I misunderstand you). Therefore,
char c = 'a';
is equivalent to
char c = 97;
Then to get a string like "97", I would recommend using sprintf, as explained in Mike's FAQ on this link.
sprintf ( s, "%d", c );
Hope this helps.
~RaGE();

I am quite a beginner myself, but I think u can use pointers to do this.
Something like:
char *ptrs=NULL;
char s[20]="a, c, d, f, l, m";
ptrs=&s[3];//pointer points le address of s[3]
printf(" %d\n", s[3]);//should print the address
*ptrs=63; //value of pointer is 63
printf(" %d\n", s[3]);//should print 63
I think this is not correct, but might give you ideas.

What is an infinite return value?
Does the file C:\My Files\SensorFile.txt exist? Do you have read permission on the file?

I have a problem that a Dialog shouldn't be left via pressing a key. I have no default button on this dialog, but pressing ENTER results in leaving the dialog with a positive result (OnOK).
Is there a way to prevent the dialog to leave when pressing ENTER without ovverriding the OnOK method?
|
|
|
|
|
What does ur default implementatino of OnOk() event do ?
If its not doing anything you can very well override it and dont call the baseclass OnOK.

Implementation of OnOK() is displaying an error message if the validation of the dialog fails.
So this is not the solution I'm looking for, because I want to prevent the execution of OnOK() and doing the validations.
|
|
|
|
|
if you disable the OnOk call then when will it be ever called and validation will be performed ?

OnOK() is called explicitely in the method which is called by pressing the "Leave" Button.
|
|
|
|
|
aah! got you..
Instead of calling OnOk when leave is pressed, instead let the Leave button call another Event that will do the validation, then implement OnOk normally to disable the enter key.

I agree it's a solution, but I think this is a bad one. Thanks.

Nope its not a bad one, its very much a accepted logic.
