Visual C++ :: How To Debug Win32 Message Loop
Sep 28, 2014You place a breakpoint at one of locations within the message loop. But I want the breakpoint to trigger when I click on the application window, for example. But I can't, it went so fast so long as I switch from VS to the application program, the breakpoint is hitted again, then the application is frozen again. I don't know how to setup a conditional breakpoint.

View 8 Replies View RelatedVisual C++ :: Debug Assertion On ActiveX Create
Oct 10, 2013I have a MFC Com Dll that has a CDialog. In the OnCreate event I create an ActiveX control. The dll is hosted inside an executable of mine. In this scenario everything works fine!
The dll is also called from an external executable and then a Debug Assertion in OCCSITE.cpp occurs when I create the ActiveX control. I suspect that in the executable there is no AfxOleInit. I spend some time with this problem and tried to CoInitialize, OleInitialize, AfxOleInitModule and even AfxOleInit in the dll. But all that does not change a thing. If I understand the mechanics then this is an intended behaviour and should be done in the host exe.
What I observed in the OCCSITE.cpp:
Code:
_AFX_THREAD_STATE* pState = AfxGetThreadState();
if (!pState->m_bNeedTerm && !AfxOleInit())
return hr;
In my executable m_bNeedTerm is 0 and in the external one (where the ActiveX does not work) it is -1. In AfxOleInit this is explained as a special flag to prevent the dll from doing an unnecessary OleInitialize. But as I said even if I call OleInitialize myself I get the Debug Assertion and the ActiveX is not visible.
Is there anything I can do to make the ActiveX control work in the external application? Obviously I cannot Change anything in the application...

Visual C++ :: Multiply Defined Symbols When Linking To DLL
Oct 24, 2013I'm building two DLLs - let's call them DLL_A and DLL_B. DLL_A builds as a standalone entity but DLL_B needs to link to the lib file for DLL_A (i.e. it imports some functionality from DLL_A). While linking DLL_B I see lots of errors taking the following form (bear in mind that port.cpp and port.h are source files in DLL_B:-
DLL_A.lib(DLL_A.dll) : error LNK2005: "public: bool __this call
std::vector<class std::basic_string<char,struct std::char_traits<char>,
class std::allocator<char> >,class std::allocator<class std::basic_string<char,struct std::char_traits<char>,
class std::allocator<char> > > >::empty(void)const " (?empty@?$vector@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@V?$allocator@V
?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@2@@std@@QBE_NXZ)
already defined in port.obj
I'm not sure if I'm reading that correctly but to me, it seems to be saying that some STL components are somehow getting exported from DLL_A (std::vector maybe?? Or std::string??) and that they conflict with similar objects already in port.obj. Sure enough, when I used dumpbin /EXPORTS on DLL_A there did seem to be some evidence that that was true. So my next step was to examine the source code for port.obj. Of course, strictly speaking I should be examining some code from DLL_A but it has hundreds of source modules so I figured that I should start by identifying whatever it is in DLL_B that's throwing up the conflict (since I at least know which module the conflict is in!).
When I examined the source files for port.obj, std::string seems to get used quite often - but fortunately I could only find one occurrence of std::vector.
In port.h it occurs here:-
Code:
class DLL_B_API Port : public boost::noncopyable {
public:
// c'tors + d'tors
int get_connections (std::vector<std::string> &) const;
// rest of class
In port.cpp it occurs here:-
Code:
int Port::get_connections (std::vector<std::string> & c) const {
if (!port_engine.available()) {
c.insert (c.end(), _connections.begin(), _connections.end());
return c.size();
}
return port_engine.get_connections (_port_handle, c);
}
Is there anything in there that would be causing the above linker error? It's entirely possible that I'm looking in the wrong place but I suppose I've got to start somewhere....
I just found a possible clue in one of the header files for DLL_A, where I found this class declaration:-
Code:
namespace PBD {
class DLL_A_API Searchpath : public std::vector<std::string> {
// Whatever...
};
}
Might that be causing std::vector<std::string> to get exported?

Visual C++ :: Debug Occasionally Brings Up Disassembly Rather Than Windows Files?
Jan 15, 2013On fairly rare occasions, when attempting to debug one of my MFC applications on VS 2010, a compilation error is encountered, and instead of bringing up the customary Windows or MFC file with a arrow pointing to the problem, a disassembly appears with an arrow pointing to one of the assembler instructions.
Since Windows assembly language is hardly my forte, I do not know how to interpret the error. Furthermore, the Output usually indicates one or more 'first chance exceptions' but little more, and the Stack output usually quite sparse and often refers cryptically to some ntdll.dll!7c92a82c().
How can I better define the compile error?
Visual C++ :: Reading Character Symbols On Lines Of Text Position By Position?
Mar 4, 2013What I have to do is write a small program in C++ to parse the symbols that are used on 5 different lines of text in each position until position 30 is reached on each line. The goal of the parsing program is to interpret the symbols (characters), if there are any per each position, on the 5 lines of text in order to output the actual data that the group of symbols represents.
My question for is this: Is there anything special from a C++ environment that should go in to something like this outside of using standard stuff like the math associated with the search algorithm that has to happen here? The symbols are located in a file, so I know I have to include "iostream" and a few other headers. But outside of header inclusions and the code necessary to iterate and streamline the search and interpretation process, am I missing anything special that I couldn't otherwise find through simple google searches?
C++ :: Coding And Debug Time Per LOC
Mar 23, 2013I just spent 3 hours writing and debugging 37 lines of code. Is this normal or am I "below average" in coding abilities. I come from a C background and decided to write C++ code that I finally got right as shown below for the specific example:
Code: #include <iostream>
#include <fstream>
#include <string>
#define SPACE_SEARCH 10
using namespace std;
[code].....
I think it was more the learning along the way that consumed atleast 75% of my time for this specific case. But then again, I read that programming always entails learning along the way and so its somehow no excuse for the long time taken in this specific case.
So as a matter of interest, what pace do all of you operate on, on average? i.e. LOC/day, Debugs per day or any other indicator of productivity?

C/C++ :: Debug Log Size Restrictions?
Dec 26, 2012Iam creating one debug log in my c++ application through the below code.
file *log;
log = fopen("C:snmpApplicationlog.txt", "w");
iam writing the statements in to this log by using fprintf(). As the .exe where i have put this mechanism runs continuously,the size of log file is increasing gradually.
1)If there is any way to restrict the Log file size,if the file reaches the mentioned size,the file should be discarded and logging should be done in another file with the same name.
{OR}
2)Put a time interval,once after that interval is elapsed, a new log file should be created.
C/C++ :: Library Has No Exported Symbols?
Jan 10, 2013I built a C++ static library using WatCom IDE. It compiles without error, but running WLIB on it produces the msg:

If I convert the Library to an .exe program, by adding a main(), it executes fine, So there seems to be something I'm missing in the IDE settings for building a .lib.

My current code is:

C/C++ :: Assigning Symbols To Numbers In 2D Array?
Sep 11, 2014I'm working on a program in C++ that is supposed to read in a file, store the content of the file into a 2D array, assign characters to each of the numbers in the array and store in a char array, and print both of these arrays. It's then supposed to go through the initial array and make sure that each number doesn't differ in value from it's neighboring numbers by more than 1, correct these errors by replacing these numbers with the value of the average of their neighbors, assign characters to this corrected array as it did before, and print both arrays.
The character assignments go as follows:
0=blank
1=.
2=,
3=_
4=!
5=+
6=*
7=#
8=$
9=&
I have the code written that opens the file and loads the array, but where to go from there. To me the obvious, although probably not best, way to do the assignments is to go through the array with a for loop and use a series of if statements to check for the value of the number at each index and assign the appropriate symbol.
Here is the code I have so far:
#include <iostream>
#include <fstream>
using namespace std;
int main() {
int size = 100, i, j;
prog >> size;
int **numArray = new int* [size];
