This code worked perfectly fine in Xcode earlier today, but when I got home on visual studio 2012 express it is having an error. It's saying that the local function definitions are illegal and has a red mark under the '{' only?
I'm trying to display a list of MSMQ messages in a list box based on a drop-down list holding the environment.So i've setup the binding and i know that the list loads but nothing shows up in the list? I should be setting like a display member or something but i'm not entirely sure
const String msmqAccelaDev = "FormatName:DIRECT=OS:tcc-intsrvTCCIntegration.MSMQ.Service.Dev/TCCMessagingService.svc";

Is it possible to alter an error message for a particular line if you think it might fail compilation? GNU specific stuff is okay. The reason I want to do it is because I have this code.
Code:
template <size_t S>
struct assertion{}
int main(){
{
volatile assertion<sizeof(config::input)> asrt = assertion<sizeof(config::output)>();
}
}
If the arrays config::input and config:utput are different sizes, I want it to be clear that that's what needs to be fixed. Is there an __attribute somewhere that will allow me to do that?

I am having trouble accessing a one-dimensional vector as a multi-dimensional one.I have a MultiArray template class, and it is accessed using the function operator. It accesses elements through the expression row * m_columns + col. The row and col are the two inputs to the operator while the m_columns is the width/number of columns in the array. There is also a version that accesses the array with one number. Its underlying representation is a one-dimensional vector.The problem is when I try to load a level:
void Map::LoadFromFile(const std::string& filename) {
std::ifstream map_file(filename);
std::cout << m_map.GetHeight() << ", " << m_map.GetWidth() << std::endl;
std::cout << m_map_dimensions.y << ", " << m_map_dimensions.x << std::endl;

I am making a console based database system. Because I have to keep inserting, editing , deleting data blocks from my record file I have decided to use either vectors or list to store the all records. From the file I shall read the entire vector/list and work with it to add , remove or edit record and then again write the entire vector/list to the file again. I figured it would stop all the weird things that happen when directly working with the file. Is it an efficient way ?Or is it totally unnecessary ?Is there a better way?

View 3 Replies View RelatedI'm currently in the middle of designing a program for some project. one part of the program is to send reminding SMS messages to the employees.
I have already subscribed to a SMS provider and they gave me an access to a control panel (aspx). But now I'm wondering how will I be able connect to the SMS server and be able to send messages?
I am new to this area and have the requirement like:
1) A running process wants to send message based on event arrival.
2)the process checks if event is critical
3)if critical then it has to send message immediately ,else send after time t.
4) The process is continuously process the events . so once it knows the event is not critical and has to send message later it has to proceed with its normal operation.. only when time 't" comes it has to come and send message.
I am adding int type into vector called "vi" several times like this.
std::vector<int> vi;
void addFunc(int *a, int cnt) {
vi.erase(vi.begin(), vi.end());
vi.clear();
for(int i=0; i<cnt; i++)
vi.push_back(a[i]);
}
and I call the addfunc N times every sec.
And sometimes it has runtime error on vi.push_back line.

I have written a function that is supposed to write a vector to a specified file. When I build the solution, I get this error:
- Semantic error. Invalid operands to binary expression.
This is the code for the function.
void file_out(vector<task>Task, string myfilename){
//writing vector to file
string file_out = myfilename;
ofstream output_file(file_out);
ostream_iterator<task> output_iterator(output_file, "
");
copy(Task.begin(), Task.end(), output_iterator);
};
The error is unclear but suggests Its received a bad pointer from another heap. It references dbgheap.c line 1322 and assertion failure
I have two string vector functions the first is called from the main function, the second is called from the first.
Their purpose is to receive a string of text and numbers in a semi-specific format, which the main body of the code reads from a text file, and delaminates the data as to return the first variable in the string as the variable name and the second as the variable value. Along the way it filters out a lot of the unwanted whitespace and punctuation.
E.g "{ VariableNameA 123 }" would be returned as "VariableNameA" And "123"
The code works perfectly for most of the lines in the text file but fails on one particular line where the first variable is 25 characters long. Basically it works for anything 22 characters or less. There are never more than 4 elements in the vector and each element is never intended to be longer than 25 characters.
It fails trying to return from the second split function to the first split function.
Is there a limit to the size of each vector element? I'm struggling to find a way round this without having to rewrite the whole thing.
vector<string> split(const string &s, char delim) {
vector<string> elems;
split(s, delim, elems);
return elems;

E.g. I can access elements directly using [] operator like vector and behave like list in terms of memory (means we don't have to shift elements if we want to insert in between like list)....

I have a property sheet view with few property pages. One of this property page contains a HTML representation via a CHtmlView derived class.
Initially, the .html file is correctly rendered. The problem is that sometimes switching between properties pages sometime the html file is not redraw. The behavior appears randomly.
According to Spy++ in such situation some Windows messages are not sent by WebControl (Internet Explorer_Server layer): WM_ERASEBKGRD, WM_PAINT or WM_NCPAINT.
Approaches such Q179421 or Q183161 are not useful. My machine runs IE 10.
The windows hierarchy is: Shell Embedding -> Shell DocObject View -> Internet Explorer_Server.
Any workaround that would determine Internet Explorer_Server layer to send these messages always?
If it is possible, I'd like to know how to intercept messages sent to controls on a dialog. I'm working on a large application with a large number of dialogs, each with a number of controls on the dialog. I need to be able to intercept messages sent to these controls so that I can determine if the controls really need to take action on these messages. I could subclass each control and override the specific event handlers but due to the volume of controls in the application this could take a very long time, will introduce risk if controls are missed, and will increase maintenance costs. What I want to do is create a class which is derived from CDialog and each of the dialogs in the application would then be derived from this new dialog class. The new dialog class would intercept messages sent to any control on the dialog and if the dialog decides that the control should do something then the dialog will pass the message on to the control.
example:
CExistingDialog is derived from CNewDialog is derived from CDialog
CExistingDialog has a number of controls. When the code in CExistingDialog calls CWnd::EnableWindow on one of these controls I want CNewDialog to intercept the message, determine what should be done with the message, and then pass it on to the control.
I'm not very familiar with the messaging framework. I've tried overriding a few of the methods of CNewDialog but none of them ever receive the message to enable the window. I assume this is because the message is sent directly to the child window (the control).
Is there any way to intercept these messages? I don't know much about hooks either but is this a possible option?

Vector based mufti-dimensional arrays
Vectors are a STL container that allow you to store pretty much anything in them. When used correctly they can be very powerful containers.
They provide an added benefit that they will automatically remove the memory they use when they go out of scope. This means that objects stored within a vector do not need to be de-allocated (but pointers to objects do). You can also do some interesting things with dynamic multidimensional arrays with vectors.
For example, if you only allocate the first dimension, then use the .push_back() to add records to the 2nd dimension it's no longer a grid, but an array with a dynamically sized 2nd dimension (much like a street of buildings each with a different amount of floors).
This functionality can be achieved using pointers, but is much harder to do.
