Well, you seem to insist on seducing us with money. Send it to me, but, as I have no Paypall Account, could you email me a few bottles of wine to the value instead? I'll share them with the other contributers on a first call first served basis.

Any way you can do this ?
Nobody asked you to make anything work relating to printers (which is what this thread is about)!

Are you per chance answering the wrong thread ?

Yes, this is a helpfull link, but mainly for initial setup. Printer Selection must be fully transparent to staff. BTW do you know of a way of extracting the Manufacturers Serial Number of the Physical Printer?

Hello,
A few months ago I asked a friend to make me a DLL that I can use in a programming language that I use (BlitzBasic).
This dll made it possible for me to use multiple mices (mouse) on a single PC, and detect them in my game.
The DLL works great and I have the source code. Unfortunatly I am not a C++ expert, I tryed to make the DLL work with TouchScreen Monitors (elotouch.com), but I just can't .
Can someone help me ?
The DLL works great, it detects when a user clicks, it detects multiple touchscreens, but it simply does not detect the X and Y coordinates. They are always 0.
I am sure that this is becouse the touchscreen does not work like a mouse.
Can someone help me with this ? I am making a school project with 3 other friends, and none of us can't seem to fix this.
The friend that made the DLL has moved to another school ... and he can't help us.
I can pay someone about 25$ (this is how much I have on paypal) if he can help.
Thank you very much.
PS: If someone thinks he can help, I will send you the source asap .

Well, That's not how this forum works, and just as well for you. At the current going rate, you just might get one line of code out of your $25.00, but, don't worry, your funds are safe. I just answer this question because you struck a chord of interest in me.

Don't understand that! Does that mean that you have several mousepointers on the screen? Or does it mean that you can have several physical mouses (mice) connected to the one computer, each moving the same single screen pointer.

Well, Join the Club. That always happens! The Crucial Question always is: Do you have the Source Code, Program Notes etc. Yoo have learned now that a 'friend' who donates a binary without those things is actually an Enemy.

The DLL sounds as if it was written in 'BlitzBasic'. why do you think that a CPP Forum can Help you. I Personally have never heard of the language, but maybe, despite it's name, its actually an MFC Library.
Have you 'Googled' for 'BlitzBasic' There is always the possibility that your 'Friend' instead of writing the dll, downloaded it, or downloaded sample code and modified it.

Hello,
Thank you for your response, and sorry if I insulted the forum with my topic .
The DLL is writen in C++, and it was made specialy for BlitzBasic, but you can use it just as well in a C++ application.
The source is not very commented, but it's only one Cpp file, that handles everything. The code is not hard, I understand it, but what I don't understand is how I can make it work with a touch screen monitor.
The DLL works detects all mice (physical) that are plugged in the computer. So you can have a logitech mouse and an a4 tech (or any other .. up to 10 mice) .
In my game, I draw 2 different cursors, on position X and Y of the specific mouse. So you view 2 different cursors, and they move independently.
Below I will give you some links, maybe (if you have time) can help.
Here is a document from ELO touch, on the touch screen monitors :
http://media.elotouch.com/pdfs/manuals/program.pdf
Here is a simple APP that works with multiple mice (just connect 2 mice on your PC and start moving them after you start the app).
http://www.sodevrom.net/sample.zip
Here is the CPP file (I have the SLN for Visual Studio, and if you think you can help, I will link that also).
http://www.sodevrom.net/RawInput.cpp
Thank you very much

Can you Publish the code on this Forum. It'll give us something to go by.

Well, the jury is out on that one! String representation in CPP and Basic are entirely different.

Hi,
Yes, this is the code made by the "unapproachable" friend .
The code is to large to post it in this topic, I uploaded the entire Visual Studio project here :
www.sodevrom.net/proj.zip
Just unzip and run SLN  .
BlitzBasic is a game making software. The ideea is that it can only work with INT and STRINGS, and that's why the DLL automaticaly converts INT and STRINGS passed by my game, in whatever he needs to work.
So this is not a problem the DLL (the source if you compile it) works now perfectly, as I sayed, but it only works with multiple mouse (mice) .
The thing is I need it to work with touchscreen monitor.
Thank you

In the init() function he sets RidInputDevice[0].usUsage = 2, this will only capture mouse messages.
Change RidInputDevice[1] to RidInputDevice[2] at start of file and init RidInputDevice[1] in init() with usUsage = 1 (pointer).
In ProcessInputData() you _may_ need 'if( ... dwType == RIM_TYPEHID )' to catch the messages, you shouldn't, pointers are considered 'mouse like' (mouse and pointer both HID_DEVICE_SYSTEM_MOUSE).
Set a breakpoint in ProcessInputData(), touch the screen, look at the data.
You'll likely need to do more. Read the MSDN doc's about the RAW input API.
...cmk

Hello,
I am trying to make this work for over 1 week now, and no luck.
I made the modifications you sayed + more.
I made the source compile to exe (console) so I can keep track of the data.
I attached a window to the console, and whenever I move the mouse/click in the window, the console prints what is happening.
The problem is that when I connect the touchscreen, and use RIM_TYPEHID , it does nothing.
I set a simpel cout<<"AA"; whenever it gets in the if RIM_TYPEHID branch, but it never does.
Any suggestions ? help ?
I also noticed that the riRawInput.data.mouse.lLastX; (and Y) for the mouse are always values that change to 0, so they are showing the motion of the mouse.
When I touch the touchscreen, the values go up to 5 000.
I don't know what to say ... I just need the touchx/y absolute position (or relative).
I hope someone can help.
Thanx

I managed to make it work.
I didn't have to make ANY Changes (add a new raw device).
The check :
riRawInput.data.mouse.usFlags == MOUSE_MOVE_RELATIVE is for mouse
and the check
riRawInput.data.mouse.usFlags == 3 is for touch screen.
After getting this, you will have to calibrate the device, and all will be perfect :
1. Prompt the user to touch the upper left corner of the video screen.
2. Save the coordinates returned as TOUCH_UL_X and
TOUCH_UL_Y.
3. Prompt the user to touch the lower right corner of the video screen.
4. Save the coordinates returned as TOUCH_LR_X and
TOUCH_LR_Y.
A good way to prompt the user to touch the corners is to draw a
border around the edge of the screen and prompt the user to touch
each point using a target in the respective corner and text centered
on the screen.
5. Calculate the four calibration parameters as follows:
OFFSET_X = TOUCH_UL_X
OFFSET_Y = TOUCH_UL_Y
SCALE_X = VIDEO_MAX_X / (TOUCH_LR_X -
TOUCH_UL_X)
SCALE_Y = VIDEO_MAX_Y / (TOUCH_LR_Y -
TOUCH_UL_Y)
6. Save the four calibration parameters to a nonvolatile storage area, if
available. If none is available, the calibration procedure must be
followed each time the system is powered up.
The floating point calibration procedure is now complete. In your
application program, convert the touch coordinates reported by the
touch system into the equivalent video coordinates with these equations:
VIDEO_X = SCALE_X * (TOUCH_X - OFFSET_X)
VIDEO_Y = SCALE_Y * (TOUCH_Y - OFFSET_Y)

Does ayone who frequents this page use the Digital Mars C++ compiler for Win32 development?
I've recently got a freebie copy of it and had a go at compiling some existing code. So far so good but the Win32 headers it ship with seem to be way behind. I need SDK 6.1 compatibility which is clearly going to be tricky.
Their site doesn't seem to be very up to date, forums are dead for the past few months and most online docs look seriously old.
Is DMC still really a live product? Is it worth me shelling out for the full version on CD? Or has MS giving away express versions of Visual Studio killed off this alternative compiler?
Any ideas as to where else to go for some answers are welcome too.

As stated by the documentation (see, for instance, [^]), you must link with ws2_32.lib library.

here is the following statement,
//////////////////////////////////
list<SOCKET> m_vClientList; // All sockets connected to client
//////////////////////////////////
I have included the #include <list>
the program in question, is an internet chat, one server to many
clients
also a declartion in the header file
/////////////////////
int SendMessagePort(string sMessage);
//////////
has a problem with (string) I know that mfc deals with CString
but in this case it might help with my query.
I gather that I need an ---#include of somesort, do you know what it is.
thanks very much

You've to include <list></list>, <string></string> and add the using namespace std; directive. For instance
#include <list>
#include <string>
using namespace std;
</string></list>

Hi all
please tell me how can i convert Convert CString[] to char[].
CString str[10];
char buff_1[]="";
buff_1= str;
error is "error C2440: '=' : cannot convert from 'CString [10]' to 'char [1]'"
Thanks in advance.
IN A DAY, WHEN YOU DON'T COME ACROSS ANY PROBLEMS - YOU CAN BE SURE THAT YOU ARE TRAVELLING IN A WRONG PATH

|

you should define buff_1 as char*:
char * buff_1;
and then:
buff_1 = (LPCTSTR)str; // for read-only purposes
buff_1 = str.GetBuffer(0); // for read-write, you will need to use ReleaseBuffer() later
Best regards,
Jaime.

They're two quite different entities:
(1) CString str[] is an array of strings.
(2) char buff[] is just 1 string.
hence the conversion does not make sense.

"_$h@nky_" wrote: CString str[10];
I'm guessing thia is not what you think it is. It's an array of 10 CString objects, not an array that holds 10 characters. In any case, try:
const char *buff_1 = str[0];

hai,
i would like to display the coding.
Means, while i m running my C/C++ program the output should be of the program coding which i m execting.....
how can i do it? Help me!
Thanks for understanding!!!

You need to (A) debug a debugger or (B) dissasemble/decompile a dissasembler/decompiler
Then, the program running would be doing nothing other than producing output that contained the program's source-code
I don't understand your question, as it stands. The effort would be pointless - an act of 'because I can'

Thanks for immediate reeply
for example...
my program coding is..
#include<stdio.h>
#include<conio.h>
void main()
{
float n1,n2,ans;
}</conio.h></stdio.h>
And the program output should be....
#include<stdio.h>
#include<conio.h>
void main()
{
float n1,n2,ans;
}
how to achieve it?
thanks in advance
