Alright, well not all is lost. Strcmp does actually seem to provide the correct behavior with the map (you can see that the strings are sorted if you print out using an iterator) and I can fix the...

I understand what you are saying. That being the case, why does this execute successfully without being determined as an invalid comparator?:



struct strCmp {
bool operator()( const char*...

I'm trying to get this running as fast as possible for processing a lot of string data and I have a working version using strcmp() as the predicate. I just want to expand the program to handle tags...

I have a map of C-strings which may have embedded tags in them (as substrings). I'm trying to find which strings have tags in them using strstr as a comparison predicate:



struct substrCmp {...

The problem was indeed the unchecked iterator. Thanks for pointing that out.

Regarding the lack of complete program flow: I went a bit overboard in cutting down the code to what I thought to be...

While loading dlls in my program I'm trying to keep a map of handles around so that I can free them later:

I have a basic dll build with a batch file I call from in the program:



CALL vcvars32.bat
cl.exe -o Script1_d.dll AIScripts.cpp AIScripts.def /ZI /LDd /link /dll
MOVE "Script1_d.dll"...

Thanks for the response, Paul. I took a look at devenv.exe but it seems to be for building with a project file, whereas I want to build directly from the source without using a project/solution.

I'm trying to use cl.exe to build some code from within my application, without much success.

Here I'm trying to get a basic compile going with the following test code:

I have a dll with a .cpp file that looks like this:



#include <Windows.h>
#include <map>

Here is the header and cpp for the AIScene class, where the pointer to the factory resides.

I'm having a heap corruption problem "CRT detected that the application wrote to memory after end of heap buffer".

The problem occurs when I add a pointer to a templated factory class I'm working...

Hi guys. I am trying to adapt some event handling code that maps an event to a function pointer to use two events mapped to the function instead, so that the function can work on the data in the...

Chris F, that's what I have in mind at the moment. What I'm wondering is if there is a way to have my program fill out the map automatically so the user doesn't have to make that function themselves.

In a project I am working on I want to put classes into a dll that will be initialized by an abstract factory and included via composition within objects in the main program. The purpose is to allow...

Looks like the crash was being caused by something unrelated. Sorry about that, if I knew how to delete the thread I would but I can't see any delete options on the edit page.

In the code for a C library I am using the author has defined some void pointers eg. here webCoreC is void*

You seem to be right about the 24bit mode being enabled but I am stumped as to how it happened. I can't find any calls to _control87() or _controlfp() in the source and it's not DirectX.

I put...

double approxLength = gauss_legendre(50,f,NULL,0,1);

Thanks for your replies guys.

Hi guys. I'm losing precision and I'm not sure why.

Length 1000.045104980468700000000000000000

The above output from my program is for two doubles....
