You have shown the code for your main program that calls the DLL but you have not indicated where it has stopped or what the code in the DLL is doing. Try stepping into the DLL code with your debugger to see why it is hanging.
It's time for a new signature.

Check the calling convention of those exported functions.
The default calling convention is __cdecl but some API function requires __stdcall.

Assume the following:
In a computer called COMPUTER there is the following folder:
c:\folder1\folder2
Now, there are 2 shares:
\\COMPUTER\NetFolder2 --> which is c:\folder1\folder2
\\COMPUTER\NetFolder1 --> which is c:\folder1
Now, I can get to through the network to "folder2" in 2 different ways:
\\COMPUTER\NetFolder2
\\COMPUTER\NetFolder1\folder2
Is there a way to check that \\COMPUTER\NetFolder2 is the same as \\COMPUTER\NetFolder1\folder2 ???
Thanks!

Hey, Thanks for your help!
No it doesn't help...
Well, I am happy to say that I just found out that Boost library can do that using boost::filesystem::equivalence() function.
But my main problem still remains...
How to tell that NetFolder1 is NetFolder2's parent?
(it is possible to iterate all the shared directories and create a data structure that will hold that data, but when there are many shared folders, it is almost insane!)
Thanks Again!!!

Hello,
I was wondering if some one can point me to the right direction to implement something similar to page layouts in MS word. I am more interested in the print layout.
Thanks

I want to be able to recognize when some pane of the statusbar is clicked. I need to know this in my View class which is derived from CView.
Any idea?
Thanks

You will probably need to use Subclassing[^] to capture events sent to the statusbar.

Hi,
I'm using the following code in visual studio 2008:
std::vector< double >::iterator location;
location=std::find(vec.begin(),vec.end(),0.);
and I'm getting the error:
error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::_Vector_iterator<_Ty,_Alloc>' (or there is no acceptable conversion)
My header files are as follows (I know all these aren't necessary for this small portion of code, but the rest of my code requires the additional headers):
#include "stdafx.h"
#include <algorithm>
#include <iostream>
#include <vector>
#include <fstream>
#include <string>
#include <ostream>
Does anyone know how to fix this? Is it possibly a visual studio project setting 
Thanks!

A fresh VC++ 2008 console project compiles the following code just fine:
#include <vector>
#include <algorithm>
int main()
{
std::vector<double> vec;
std::vector< double >::iterator location;
location=std::find(vec.begin(),vec.end(),0.);
}
Also, be careful when comparing floating-point numbers[^]

Hi everyone,
I'm using a vector of vectors to mimic a matrix using the following:
vector < vector <long double> > data_matrix;
I then add "rows" using the following:
for (int z=0;z<13;z++)
data_matrix.push_back(vector <long double>());
Next, I load the appropriate values (from an input file) into the vector of vectors (some the values will be zeroes).
What I'd like to do, is to search a particular "column" for zeroes and eliminate them in that column as well as the corresponding entries in the adjacent columns (so in effect, eliminate an entire row). I've figured out how to delete zeros from any given vector in the vector of vectors using:
bool IsEven (double d)
{
return (d) == 0;
}
data_matrix[0].erase(std::remove_if(data_matrix[0].begin(),data_matrix[0].end(),IsEven), data_matrix[0].end());
Does anyone know how to do this
The number of entries in each of the columns are the same.
Thanks!

Can you give us an example of what happens when you, for example, reduce a 3 by 3 matrix like:
1 1 1
0 2 2
3 3 3
Would you expect to end up with the following matrix?
1 1 1
3 3 3
If so you can do it with remove_if on the vector of rows - you remove any row that has a zero element in it. The predicate will have the form:
bool contains_zero( const std::vector<long double> &row )
{
....
}
Cheers,
Ash
PS: If you're using a compiler that supports them you can write the predicate as a lambda rather than as a function.
PPS: Just out of interest you can get rid of the loop:
for (int z=0;<13;z++) data_matrix.push_back(vector <long double>());
Have a look for a constructor for vector that takes a size or consider using std::generate_n to do it all in one fell swoop.

Hi Ash,
Thanks for replying. You're example matrix is what I'd expect. The way my vector of vectors is set up is that each of the vectors actually contains the data from the particular column (instead of row). This is why I seem to be having trouble.
For example (when referring to your sample matrix):
vector[0] would contain 1 0 3
vector[1] would contain 0 2 2
vector[2] would contain 3 3 3
So for example, the code and predicate that I previously posted which used "remove_if" would make vector[0] = 1 3 which would then give:
1 1 1
3 2 2
3 3
but not:
1 1 1
3 3 3
I should have mentioned that key piece of information (that the vectors hold columnar data instead of row date), sorry about that.
Any ideas for this scenario
Thanks,
|

Ouch, it's a bit messier but...
- for each column use std::find to locate any zeros. Record the indices of the rows the zeros are in somewhere, maybe another vector or a perhaps a set. (std::find returns an iterator, you'll have to subtract column.begin() from that to get the index from the iterator).
- for every row there's a zero in, zero every column element in that row.
- for each column use the combination of std::remove_if and std::erase you presented in the question to eliminate the zeros.
Hope that's clear enough - if not feel free to ask what I'm wittering on about,
Ash

Thanks Ash,
Sounds good, I'll give this a try.

I want to change MyApp to some other text.
I can change untitle to any other value but i want to change MyApp

Check out the IDR_MAINFRAME string resource.

Yes IDR_MAINFRAME string variable will work
but I want to change dynamically?

Have you tried calling SetWindowText() from within the frame's ActivateFrame() or OnCreate() method?

SetTitle()[^] is the most common method for changing it dynamically.
It's time for a new signature.

Hi,
It is not working.
SetTitle will change untitled to some value
but MyApp will won't change.

Sorry, I'm very rusty on my MFC, try SetWindowText()[^].

Try that ^.

You can solve the problem inspired from here. It's working 100%.
