Ive made a program with MFC and when i try to run it on another computer its asking for loads of dll files , is there some thing i gotta install to get this to work?

if you want to disturbute ur exe file, then you need to build it under release mode. If your application is using some ActiveX components, then you need to copy them and register it too.

In "Project setting" - General select "Use MFC in Static Library".

its a good idea but it will increase the binary to a huge one, like in MBs you dont want ur customers to download ur file from the net that does a small task but takes ages to download.

The customer will need to download the DLLs anyway. I doubt 98 comes with the VS.NET C RTLs made in 2002.

For MFC you need MFC42.dll, if you've used C as well as C++, you probably need MSVCRT as well.

Hi everyone
I have little problem with determining correct AddressOfEntryPoint in PE headers. When this param is incorrect, then I try execute exe file, Windows says, that isn't Win32 application.
How to programmatically check, which value should be contain AddressOfEntryPoint ? Is it possible to determine correct value based on other parts PE headers e.g. IMAGE_DATA_DIRECTORY ?
snippet of source code will be blessing

AddressOfEntryPoint is a realative value, that means it points to a address in the file.
Have a look at some PE tutorials, they will show you how to calculate the right value.
Don't try it, just do it!

Are you using http 1.1 protocol??? If so why dont you refer RFC2068 on http 1/1 protocol.

i guess you can send data either using post or get method.
I guess get method is pretty straight forward. for post method you (and me) need more info how to do it (reference the rfc doc)
it would go like this.
Make the socket connection with the webserver.
Then depending upon POST or GET you send send the data.
I hope i am getting ur question correctly.

Hello, everyone!
I am looking for a safe and efficient way to use two dimensional arrays, better a library that I can use in C/C++.
Here is the way that I used before, allocate a pointer array, and then allocate memory pointed by each pointer in the array (size of each memory block pointed by each pointer may be vary and I always use an additional one dimensional array to record each of their size). But I find it is hard to manage (for example, release/free memory), because all the space the two dimensional array using is allocated on the heap and not on the stack, and
it is easy to result in memory leak if the management mechanism is not sound. And I want to supply an unified interface to client applications using the library, who uses the memory block as a two dimentional array, for example, A[i][j], and not using it as pointers, for example, *(A + i + j). Maybe to implement that function, I need a wrapper or a middle layer.
What I am looking for is a safe and efficient way to define, allocate space, manipulate and free (free part or all of the two dimensional array). Can anyone help? Are there some source codes or tutorials that I can make a reference?
Thanks in advance,
George

One of the safest ways would be to use standard library components.
std::vector<std::vector< your_type > > storage;
From a performance perspective this will be fine, unless you need to make lots of copies. Situations that involve many copies tend to come up in matrix maths. If that's the case it's worth looking for a library which uses templated operators to remove the overhead of the temporaries involved in such expressions. If that's the case look at boost::blas or blitz ( ? I think)

Thanks, Andrew buddy!
STL vector is useful in C++. But sometimes I need to use the same function in a pure C environment. What can I use in a pure C environment?
Have a nice weekend,

int main(int argc, char *argv[])
{
unsigned i;
// Declaration of the two-dimensional array
// as a pointer to pointer
//
char** array_2D;
const unsigned ROWS = 10;
const unsigned COLUMNS = 10;
// Allocate "main" array
//
array_2D = new char*[ROWS];
// Allocate each member of the "main" array
//
for (i = 0; i < ROWS; ++i)
array_2D[i] = new char[COLUMNS];
// Fill the 6th element with a string and print it
// out
//
strcpy(array_2D[5], "Hey there");
cout << array_2D[5] << endl;
// Deletion is performed in reversed order.
// Pay special attention to the delete[] operator
// which must be used to delete arrays (instead
// of the "simple" delete)
//
for (i = 0; i < ROWS; ++i)
delete[] array_2D[i];
delete[] array_2D;
return 0;

In C programming he should be using malloc and free, not new and delete.

Yes, Nick buddy!
It is a constant rule.

Thanks for reply, Branislav buddy!
Your sample code is helpful. I have another question, how to use "array_2D" looking as a two dimensional array? I mean, in your sample, you use it as one dimentional array, for example, "array_2D[5]". I want to know how to use it looking as a two dimentional array, for example, array_2D [i][j]? Need to add additional wrappers or interface?
Best regards,
George

There are two dimensional array as like array_2D [i][j]. You can use something like this:
int** array_2D;
const unsigned ROWS = 10;
const unsigned COLUMNS = 10;
// initialize rows
array_2D = new int*[ROWS];
// initialize columns
for (int i = 0; i < ROWS; ++i)
array_2D[i] = new int[COLUMNS];
// fill 2d array with 0
for ( int y = 0; y < ROWS; y++ )
for ( int x = 0; x < COLUMNS; x++)
array_2D[x][y] = 0;
// after work try to make the free memory
for (i = 0; i < ROWS; ++i) { delete[] array_2D[i]; }
delete[] array_2D;
