Can I point out that if you really want portability with C++11, we do this and there is nothing your code can do with this as it uses the standard vector library
using namespace std;
#define YMAX 6
#define XMAX 4
// single line to define a 2D array of floats
vector<vector<float>> matrix1(YMAX, vector<float>(XMAX));
// Now you can just set values
matrix1 = 3.6f;
matrix1 = 4.0f;
matrix1 = 8.0f;
// Or read them back
float f = matrix1;
The really cute part is it can be used on any standard type
// single line to define a 2D array of STRINGS
vector<vector<string>> stringmatrix(YMAX, vector<string>(XMAX));
// writing strings in the array
stringmatrix = "hello at 0,0";
stringmatrix = "this one";
stringmatrix = "hello at 5,3";
// Getting string value from the array
string whatdidwesay = stringmatrix;
Increase Baudrate of CSocket and reduce data chunk size while communication.. big data if reduced to small data chunks with sequence added in the data packet may help in faster data transfer across systems.. look in windows provided CSocket for more info
int uwSeq;// sequencing starts from 1 upto 879
int maxSeqCount;// when this reaches 879 reaset to 1
char myData;//Small Chunk
unsigned int uwcrcData;//CRC of uwSeq,myData
send stSmallChunk data packet and validate at other end using CRC recieved seqs.
I am looking for an article about dialing a phone number directly from my database (i.e. as in Call Centre), Via CPP Code. I do not seem to be able to filter the article count down to less than 3700, mostly altogether unrelated. Anyone a Hint or Idea?
It is an MFC42/CPP Desktop Application I want to Auto Dial from, to establish a Voice Connection. I.e.: I want staff to contact selected customers, via de Phone Number we have on our DB. As a Laundrette, we have an issue with customers forgetting they left stuff in. I'm writing an MFC Application for staff to deal with this during quiet times. Automatic dialling helps to prevent mis-dials, and protects our phone bill against misuse.
I am planning to connect Via a "RealTech" Dial up Modem Card, or Equivalent. All my XP Computers have one, or something similar, by a different manufacturer. I also harvested about half a dozen. The Installation software is typically part of WinXP.
The XP Default installation is that specific and unspecified features may not be available. However, I seek only Voice Contact, on an Out Dialling only Connection.
I have also a number of Installation disks for older Real Tech Modems which I bought in the past. I suppose that any and all of them can do a basic Function, Dialling out, and thereafter managing a Voice Based conversation. All Computers we currently have, have also a form of sound processing card.(Very Basic in most cases) I assume that this can be used to get the Voice Aspect realised for a phone connection.
Al I am ultimately interested in is, getting an outgoing Voice Connection.
We have NO requirement at all, to deal with in coming calls.
I Think we are both rumbled by gremlins. My Post was somehow split in two by the CodeProject Server.
Let us Discard One Thread, I Propose This One!
Otherwise: My Reply to This One is:
You must be under pressure, but, I know how that feels. Answered this question before in this thread, However,it is a Desktop Task, in MFC42. I am not looking for a Solution, but for an article(hopefully Old, so that it appreciates the limitations of MFc42) in CodeProject, or elsewhere. Even a Title of a book will do.
(Mental Block I had, not looking for 'Modems' in the first place!), as you know, that's how it goes.
However, it covers, apart from a sprinkling of C or CPP, a Lot of CE, C#, etc, which have their own libraries, etc, and hence are instructive, but not very useful. For Instance, "Phone.Lib" is not a component of MFC42.
All I need to do is the Dialling, and the Channelling of the connection to the Sound System, and hanging up, after ending the call.
I'm going to try for now something called "RasDial.exe" and see how I get on with it. Hopefully I can fool it in not looking for a Phonebook Entry, or stopping it from trying to make an Internet Connection.
I have also bought a £6.00 USB Dialup Modem which comes with a CD. Hopefully the CD contains something useful. I live in hope. Even if it fails, the cost is less than a packet of cigs, and, I still have the Modem.
Hope if all else fails to be able to hang a Head Set and Mike to the 'Phone' Output, and, hope the Modem can do the Dialling via the Line Socket.
May need to set to Pulse, and a switch to isolate the head set, (I know how POTS works) but, for now hope we can make it work without having to resort to this.
Worth Six Pound to try it, though, even if it does not work!
Thanks, and, I'll keep you Posted, but, remember, I'm on my own, and have to resolve many issues, all by myself. If I get an Intractable Problem in One Place, I put it aside, for dealing with, and whilst waiting, tackle something else. That keeps the entire front moving.
No, Richard gave you the link all child windows are automatically disposed.
Your only responsibility is to cleanup any memory allocation, handles etc you specifically created. You do that by intercepting the WM_DESTROY message and cleaning up there. WM_DESTROY is sent just before the window is deleted but while the window is actually still valid.
Typically you create things in the WM_CREATE and you dispose of it in the WM_DESTROY.
