C / C++ / MFC

I recently encountered this ambiguous symbol issue and found a solution. Posting here in this old thread for reference. I had the same issue in a project where I needed to include both <afxmt.h> and <atlsync.h>. They each have a similar set of concurrency classes with the same names -- but for a given class some of the member functions are distinct. In Visual Studio 2022 build 17.4.3 with the latest Windows 10 SDK (and perhaps in older IDEs and SDKs), you can reference classes from both of these headers without ambiguity, so long as you: 1) Include afxmt.h BEFORE including atlsync.h, e.g. `#include ` `#include ` 2) Do NOT specify using namespace ATL 3) To reference a class in atlsync.h, preface the class name with ATL::, e.g. ATL::CEvent or ATL::CSemaphore. If you do not add this ATL:: namespace preface, the class will be referenced from afxmt.h.

just tried it that did it thank you :)

Yes, mine was concise, but your comments still added some good detail.

I had a buffer that was way too small it overlayed data inluding the pointer to the map class thanks

thanks beginning to see there is not a way to do what I want with operator overloading

I understand at this point I am trying to get the =operator overload working I think it’s only referencing the first byte as opposed to 4 bytes Thought if I cast it it would work but didn’t going to try to move it to a int

thanks, I tried that BTW I looked at the value of the iterator in storage and seems it prefixes my data with a int with the value of the entry number Thank you again

Thank you again you know I’m an assembler mail framer by birth when I post any question on IBMMAIN no matter how much research I have done I get screamed at wish IBMMAIN could be more like the codeproject thank. Time for to implement my code or actually yours

For the VC++ side, make sure you have more than just the pre-processor definition. Check out the Project Properties -> General -> Project Defaults -> Character Set setting too. For the VB6 side, I'm pretty sure VB6 uses Unicode to store strings internally (going off of memory). But, that doesn't mean the app is Unicode enabled. The VB runtime will most likely convert the string into whatever code page the system is running. Now, for lower end chars in something like UTF-8 this isn't an issue... BUT... when VC++ says Unicode they mean UTF-16. So there will be a byte alignment issue where the Unicode DLL is treating every two characters as one for your prodId, for instance. I'm not sure of the error you're getting, but if you're looking to interface VB6 with a DLL, you may be better off using Multibyte Character Set (MBCS)[^]. I haven't verified it, but MBCS is probably closer to what VB6 is doing anyway. Jeremy Falcon

it would be polite to let us know if things are working now... Charlie Gilley “They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.” BF, 1759 Has never been more appropriate.

Automation is for automating your daily tasks or industrial stuff that can be done by robots. It is a great addition to the modern world. There are many types of automation like robotic process automation, personal automation, industrial automation, and flexible automation.

I've fixed you program for you, in order to perform correctly the multiplication case. All the other ones are up to you. #include using std::cout; using std::cin; using std::endl; #include #include void showMenu(); int getResponse(); void correctMessage( ); void incorrectMessage( ); void multiplication( ); int main() { int response; //NOTE: each time you finish writing a function and want to test it, //uncomment the case within the switch that calls that function. while ( ( response = getResponse() ) != 5 ) { switch( response ) { case 1: multiplication(); cout<<"\n\n"; break; //case 2: numberGuess(); cout<<"\n\n"; break; //case 3: printSquare(); cout<<"\n\n"; break; //case 4: calculatePayroll(); cout<<"\n\n"; break; default: if ( response < 5) cout << "sorry, not yet implemented\n\n"; break; } } cout<<"\n\nThank you and have a nice day!\n\n"; return 0; } void showMenu() { system("cls"); cout<<"***********************************\n"; cout<<"* Press 1 to do multiplication *\n"; cout<<"* Press 2 to play number guessing *\n"; cout<<"* Press 3 to print a square *\n"; cout<<"* Press 4 to calculate payroll *\n"; cout<<"* Press 5 to Quit *\n"; cout<<"***********************************\n"; cout<<"=====> "; } int getResponse() { int response; showMenu(); cin>> response; while( response < 1 || response > 5) { showMenu(); cin >> response; } return response; } void correctMessage( void ) { cout << "Very good!\n"; } void incorrectMessage( void ) { cout << "No. Please try again.\n"; } void multiplication( void ) { int x, y, response = 0; srand( time( 0 ) ); while ( response != -1 ) { x = rand() % 10; y = rand() % 10; cout << "How much is " << x << " times " << y<< " (-1 to End)? "; cin >> response; while ( response != -1 && response != x * y ) { incorrectMessage(); cin >> response; } if ( response != -1 ) { correctMessage(); } } } "In testa che avete, Signor di Ceprano?" -- Rigoletto

One thing I do notice is at the following line: memcpy(exec, input, sizeof input); If input is changed in any way after calling Reverse then sizeof may not reflect the modified size. Oh, and obviously you have converted it to a string, and not to a sequence of machine code instructions.
