Maybe uneeded ideas but
- if the users would drag the file to your program instead of doubleclicking on it, you would not have the problem of multiple copies. Then the file is made known to your program by a drop-interface.
- if you could make a small program that copies file(s) to a folder you could use winAPI- functions findfirstchangenotification()/FindNextChangeNotification() to watch this folder with another program. Your basic commands then could also be transfered as files to the folder by the small program, and you could check then if the file(s)/commands sent are processed (because the other program moves them to another folder after processing). When not processed within time the other program is not running (or just too slow) but everything is queued..
That's what came in my mind reading your questions...

Actually, the original draft for this program was very similar to that... it was going to be a macro in Visual Basic Script that would run in the AS/400 client window... and the original way it was going to work was that Excel would generate the file (via Visual Basic for Applications) and copy it into a specific directory. In the meantime, the AS/400 VB script program would cycle through checking for the existence of files (they would be named like file1, file2, etc. but there would also be a particular filename the user could save a text file as and drag into the folder and it would look for that too). When it would see a file, it would process it and then move into a "finished" folder and add to a log that it did it and then move back to looking for the next file in sequence and if there wasn't a #2 or #3, etc. it would go up to about five past where it was and then start over at 1.
When I was working on designing the actual scripting language, I quickly realized that the program was blossoming into something that would be unweildy to run in BASIC, so I moved to C++ and a whole world of options opened up. When I started thinking how does a regular application work, I decided I want to try these other methods in addition. (It might still do the directory scan thing too.) Plus, having a stand-alone program frees up Excel and the AS/400 window because currently I do have Excel pushing into the AS/400 but I can't use either system until it is done.
I will start by first just having a FILE/OPEN or right-click on the queue and choose add... but in thinking ahead because changing structure sometimes requires rewriting the whole program, I'd like to have an idea of how to structure from the beginning so that I don't have to rework the program.
Good ideas, though... I will play with what I have seen so far and if I can have six or seven ways of opening the file, all the more useful for anyone who will be using it later. I just want to make it easy to pick up and use.

hello i tried to link this two file:
#include<list.h>
template <class T>class hash{
public:
list<int> *l;
int m,n;//k is the entry and m is number of slots and n is the size of our array
hash(){
l=new list<T>[n];
n=m=0;
}
hash(int n1,int m1){
n=n1;
m=m1;
l=new list<T>[n];
}
int hashfunct(T k){
return k % m;
}
void print_hash (){
for(int i=0;i<n;i++)
while(!l[i].empty()){
cout<<"l["<<i<<"]="<<l[i].front()<<" ";
l[i].pop_front();
cout<<endl;
}
}
list<T>* add_to_hash(T k){
int key=h.hashfunct(k);
l[key].push_front(k);
return l;
}
};
and the main program:
#include<iostream>
#include<stdlib.h>
#include "/home/sajad/src/ds/test/hashfunctions/hash.h "
using namespace std;
int main(){
int n;
int m;
cout<<"please enter n(number of entries):"<<endl;
cin>>n;
cout<<"please enter m(the dividisor number,must be near n):"<<endl;
cin>>m;
int a[n];
for(int i=0;i<n;i++)
a[i]=0;
hash<int>h(n,m);
cout<<"please enter n numbers:"<<endl;
for(int i=0;i<n;i++){
cin>>a[i];
h.add_to_hash(a[i]);
}
cout<<"after hashing:"<<endl;
h.print_hash();
return 0;
}
the address of hash.h is completely true but i face this error:
[sajad@sajad hashfunctions]$ g++ my\ hashing.cpp
my hashing.cpp:4:57: error: /home/sajad/src/ds/test/hashfunctions/hash.h : No such file or directory

Well, the error message is actually very clear:
the path
/home/sajad/src/ds/test/hashfunctions/hash.h
is wrong.
BTW Why don't you use relative paths?

i also used #include "hash.h" but yet this takes error!!!

If the path is wrong then it is wrong (and the preprocessor cannot include the header file).
Go to the folder containing the header file and type pwd (I'm assuming you're developing for a Linux or Unix machine) to see the correct path.

[sajad@sajad hashfunctions]$ pwd
/home/sajad/src/ds/test/hashfunctions
that this is the last location in the file header.

I see an extra space at the end of the string...

oh ... excuse me ,i test it with devcpp and it does not have any error with it!!! 
thanx.

i am looking for for this code.
if you have it, please share.
|
|
|
|

Would you please stop asking for full code ? Please read the posting guidelines and try to start by yourself. Once you are stuck, come back with a specific question.
Besides, your question as it this now doesn't make any sense...

Please ask of google for full code not us.

Yesterday you were asking "can you define polygon?" and now you are asking for that?
I would suggest you to go back to school, and restart the whole mathe contents.
BTW, if you want us to make your homework... you should considering hiring someone and pay his/her salary. Otherwise you are not going to get any other "full code" from people here.
Regards.

Hi,
In my coding i initialized null to CString.Im comoaring NULL character to that string.But it returns wrong value.See my code.
CString ExeMonFile=_T("");
int NoExeMonFile=1;
if(strcmp(ExeMonFile,"")!=0)
NoExeMonFile=0;
By debugging the NoExeMonFile became 0.
Then i found that ExeMonFile is initialized to some other text.How its possible.
I declared ExeMonFile Globally.
Im using VS2008.Whats the betterway to initialize CString .

You dont need to intilalize CString, the constructor of CString will take of this. By default it will set the CString to an empty string.
Anu_Bala wrote: if(strcmp(ExeMonFile,"")!=0)
The best way to check wheather a CString is empty or not is to use the IsEmpty() function of CString.

But in my applcaiton in default it will assign to some "BL001" not only for this CString.
Whatever CString im using in this applcation all are initialized to this "BL001".
Just i converted VC++6.0 to VS2008.
After that only this problem arised.

How did you verify the content in the CString? while debugging or you tried to display the content in some message box?
If the optimisation is no disabled, there is a chance that the debugger show incorrect value while debugging( check project properties->c++->optimization )
|
|
|
|
|
My optimization setting is Disabled (/Od)
While debugging while keeping cursor on this CString variable it shows "BL001"
Actually BL001 is one term stored in char szModelName[10].
But why its get copied in all CString varialbes used in various classes.
Even in some dialog,in edit boxes it displayed to BL001 instead of empty box.

Thats bit strange. Some memory corruption I guess.
Let me ask. Have you called CString::GetBuffer() at some place and didnt call CString::Releasebuffer()?
|
|
|
|
|
When i searched for GetBuffer() in my coding,i get four or five GetBuffer() lines.
But unfortunately there is no ReleaseBuffer().
But where i using GetBuffer(),that CString is not related to above mentioned CString.
Im confused may it cause problem to all CString varialbles?
