I want to build an application with publish/subscribe model for UDP communication for a real time simulation system. I'm new to this communication model and need to know much about the publish/subscribe model. We are using the Client/Server model for the communication. Where can I get some details about this model and what is the middleware I should be using.
Thanks

I bet Google has lots of information.

GetOpenFileName() is Win32 API function which accepts a pointer to a OPENFILENAME structure. In this structure, you have to set up a member lStructSize to sizeof(OPENFILENAME) for Windows XP and above. But for Windows98 it must be OPENFILENAME_SIZE_VERSION_400. When I use an if statement to do it, compiler gives fatal error and stops :
OPENFILENAME ofn;
if(win98()==FALSE)
ofn.lStructSize = sizeof(OPENFILENAME);
else
ofn.lStructSize = OPENFILENAME_SIZE_VERSION_400;
Ofcourse I can make seperate functions for opening files in win98 etc. But what is a better way to do this.
Thank you

What is the error that you get?

This is what Pelles C Compiler displays :
Building MAIN.obj.
C:\Code\Hasher\MAIN.C(34): fatal error: Internal error: get_rule().
*** Error code: 1 ***
Done.
|
|
|
|
|
From the code that you pasted, I'm not able to figure out what the problem is.
The if condition looks perfect.
Is that on line 34 of main.c?
|
|
|
|
|
Yes. Its line # 34 in main.c
When I remove if statement and just set lStructSize to one of the values, the code compiles perfectly.
|
|
|
|
|
It seems that there is nothing unusual.
Give it a try by changing the name of the function "win98". It might confuse the compiler? 
|
|
|
|
|
What does the win98() function do?

I am trying to sort a list using the insertion sort algo, but my application crashes. I think those pointers lost track by using the remove function. Is there a better way to sort except using the sort() (list.sort() function). It does not work too well with it since I am sorting by Departure Time of the object in the list.
Here is the code i wrote:
//Insertion sort to sort runs by departure time in the Res_RunList
int numruns = Res_RunList.size(); //the size of the list
ListOfRuns::iterator Tempitr1; //create itr poniters to navigate thru the list
ListOfRuns::iterator Tempitr2;
ListOfRuns::iterator Tempitr3;
ListOfRuns::iterator Tempitr4;
ListOfRuns::iterator Tempitr5;
ListOfRuns::iterator Tempitr6;
std::list <RDLRun*> TempList;
ListOfRuns::iterator Tempitr7;
Tempitr1 = Res_RunList.begin(); //points to the 1st element
Tempitr2 = Res_RunList.begin();
Tempitr6 = Res_RunList.begin();
for(int low = 1; low < numruns; ++low)
{
++Tempitr2; //points to low position
RDLRun *TempRun = (*Tempitr2); // store the data from low position in TempRun
int u = low -1;
Tempitr3 = Tempitr2;
Tempitr4 = Tempitr3--; //ponits to u position
//compare the time windows
while(u >=0 && ( (*Tempitr4)->GetDepartureTime() > TempRun->GetDepartureTime() ) )
{
Tempitr5 = Tempitr4;
Res_RunList.insert(Tempitr5++, (*Tempitr4));
Res_RunList.remove((*Tempitr5++));//to prevent duplicate
--u;
--Tempitr3;
}//end while loop
if(u > 0 || TempRun->GetDepartureTime() > (*Tempitr1)->GetDepartureTime())
{ Res_RunList.insert(Tempitr4++, TempRun);
Res_RunList.remove((*Tempitr4++));
}
else{
Res_RunList.insert(Tempitr6++, (*Tempitr1));
Res_RunList.remove((*Tempitr6++)); Res_RunList.insert(Tempitr1, TempRun);
}
}//end for loop
Thanks.

I don't see you using sort in your code.
Also, any insertion or deletion in the list renders the iterators invalid.
This can give you unexpected results.
|
|
|
|
|
Do you know of any better way to approach this scenario? Sort those objects in acending order by within a list?
Thanks.
|
|

The best approach is to use TempList.sort(MyCompare<RDLRun*>());
Here MyCompare is a functor used to decide how to sort the list of RDLRun class pointers.

Thanks for the insight. I have create a little functor to work with the sort function but getting an error. there is something that I am not doing right. Thanks for your help.
Functor code:
bool RDLTemporaryResource::SortByTime:public std::binary_function<RDLRun*, RDLRun*, bool>
{
bool operator() (RDLRun* a, RDLRun* b) const
{
if( a->GetDepartureTime() < b->GetDepartureTime() )
return 1;
else return 0;
}
}

1) Write the data to the printer (driver) using code.
2) Write the data to a text file, and use ShellExecute(hWnd, "print", "data.txt", ...) on that text file. This will default to Notepad, but you can specify Winword.exe instead.
3) Use Word Automation.

An exe uses a dll file.
If only code inside function body of the dll file was changed (no functions were added or deleted and function signitures were not changed), but exe itself was not re-compiled, may the dll cause any dangrous (or problem) for the exe file?
the Q related to software auto-updates.
For lite reason, I don't want to update exe when update dll.

As long as the function signatures which are called by the executable are the same there should be no problems. You can even add resources or additional functions without any problems.

Hi,
It is safe to change the internal implementation of the exported functions, as long as you retain the signature. It is also perfectly safe to add more new functions, but you should not remove an existing function that may be used by the executable.

Yes that is safe, also see binary compatibility[^] for more background on the topic.

hello, i am having a problem with this code. I do not know what is wrong. I enter the begbal, the ourdep and the withdraw. But in the end when goes to get the final balance. The answer is always the same as the input of begin bal. Any help would be greatful.
#include <stdio.h>
#define SENTINEL 0
float endbal,
finbal;
int date,
outdep,
withdraw;
int main (void)
{
printf("BANK RECONCILIATION FOR: 10/21/98");
printf("\n\nEnding balance on statement:");
scanf ("%f", & endbal);
printf("Enter Outstanding dep (or %d to quit)>", SENTINEL);
scanf ("%d", & outdep);
while (outdep!= SENTINEL)
{
finbal = finbal + outdep;
printf("Enter outstanding dep (%d to quit)>", SENTINEL);
scanf("%f", & outdep);
}
printf("Outstanding check/withdrawal (or %d to quit)>", SENTINEL);
scanf ("%d", & withdraw);
while (withdraw!=SENTINEL)
{
finbal = finbal - withdraw;
printf("Enter withdrawal (%d to quit)>", SENTINEL);
scanf("%f", & withdraw);
}
finbal = endbal + outdep - withdraw;
printf("Your final balance in your checkbook should be $ %f" , finbal);
return 0;
}

Change
kbury wrote: printf("\n\nEnding balance on statement:");
scanf ("%f", & endbal);
to
printf("\n\nEnding balance on statement:");
scanf ("%f", & finbal);
and then remove the following line

I made the changes and did the execute, this is what came out. still not the right answer. I do not know what else to do with this. I have tried so many things.
BANK RECONCILIATION FOR: 10/21/98
Ending balance on statement:20
Enter outstanding dep (0 to quit)>10
Enter outstanding dep (0 to quit)>10
Enter outstanding dep (0 to quit)>10
Enter outstanding dep (0 to quit)>0
Enter outstanding dep (0 to quit)>0
Outstanding check/withdrawal (or 0 to quit)>10
Enter withdrawal (0 to quit)>10
Enter withdrawal (0 to quit)>0
Your final balance in your checkbook should be $ 2185232384.000000
"c:\cop2000\a5\lcc2\score.exe"
Return code 0
Execution time 12.438 seconds

Well, I didn't notice you made a bad mix of floats and ints.
Try
#define SENTINEL 0
int endbal,
finbal,
date,
outdep,
withdraw;
#include <stdio.h>
int main (void)
{
printf("BANK RECONCILIATION FOR: 10/21/98");
printf("\n\nEnding balance on statement:");
scanf ("%d", & finbal);
printf("Enter Outstanding dep (or %d to quit)>", SENTINEL);
scanf ("%d", & outdep);
while (outdep!= SENTINEL)
{
finbal = finbal + outdep;
printf("Enter outstanding dep (%d to quit)>", SENTINEL);
scanf("%d", & outdep);
}
printf("Outstanding check/withdrawal (or %d to quit)>", SENTINEL);
scanf ("%d", & withdraw);
while (withdraw!=SENTINEL)
{
finbal = finbal - withdraw;
printf("Enter withdrawal (%d to quit)>", SENTINEL);
scanf("%d", & withdraw);
}
printf("Your final balance in your checkbook should be $ %d" , finbal);
return 0;
}
