most simple app for Visual Studio

Windows 10, Visual Studio 2008 and 2012

I want to create a simple app that is nothing more than this:
main()
{
for( int i = 1; i < 10; i++ )
{
GetCursorPos( &position );
Change_Position( &position );
SetCursorPos( &position );
sleep( 1000 );
}
}

The use of Win32 Project brings in hoards of unwanted things. Is there such a thing as a simple Visual Studio project that will meet this concept? Is Win32 Project the simplest that can be created?

Taskbar visibility

December 11, 2015, 2:13 am
$

Hello,

I have an application (A) which can host a MFC application (B) inside. A creates the B process, finds the window handle of B, calls SetParent to make B a child window and MoveWindow to adjust the position of B so it fits inside.

Application A is run in fullscreen which hides the taskbar. However, application B must not be maximized since it has to be shown inside A's window.

When working in the window that belongs to B (for example clicking on the ribbon application button and then in the view) the taskbar becomes visible. It's only when clicking on the portion of the screen that belongs to A that the taskbar hides again.

I couldn't find which function in the Windows API that triggers the taskbar visibility. For example, it doesn't trigger if a mainframe window is maximized and WS_CAPTION is removed during style modification.

I don't want the taskbar to be shown during the lifetime of A. Can the "fullscreen behaviour" be simulated for a child window that doesn't fill the screen? The "fullscreen behaviour" is apparently not inherited by just calling SetParent.

Any advice would be appreciated!

Forum application/program programming project (outsource) -- recruiting coders

December 14, 2015, 12:24 pm
$

The project consists of a monitoring program for forums. The primary operations consists of reading (downloading posts,pages,replies, ect.), writing (uploading posts,pages,replies, ect.),
direct interactive reading/writing (chat,Flickr, Facebook, Instagram, Pinterest, SMS,Tweeter,instant message (IM) ing with users (with the help of word file)), and of
coarse logging and analizing logs with the use of different algorythms.The writings (uploads) is the outcome of the just mentioned analysis,depending on the combination of the occurance of words
(more on the in the detailed spec). The log/analisys is based on different aspect of data like the type of forum,location of (forum,proxy,user),type of user,time,type of sub-item
(post,page,poll, ect.),Internet protocol used,social network,Web page layout,data formats,char sets,end user hardware device (terminal,PC,tablet,cell, ),OS (Window,UNIX/LINUX,MAC, ect.)
The program would have to:
- use of multiple proxies (to maximize network bandwidth)
- use of multiple CPU/memory adresse (central and withing certain higher level proxies)
- multi-thread (withing each CPU)
- account for network failliures/downtime and have to be auto-reentrant/restart (auto fixing damaged/incomplete data)
- use multiple Internet protocols high level protocols (FTP,HTTP,IRC, ect.)
- use multiple Internet protocols low level protocols (TCP,UDP,MDCP,IP, ect.) for multiple Internet protocols schemes (unicast,multicast,broadcast)
- use multiple low level Internet Protocol Format (IPv4, IPv6, ect.)
- use multiple Network Traffic Route (amongst main program and proxies,and proxies and forum sites)
- taking into account for network optimisation network profile of proxies/end forums/sites
- type of Internet connection (cable, DSL, fiber optic, satellite, ect.)
- baudrate of Internet connection
- Web server (forum) software
- proxy software
- Web server (forum) OS
- proxy OS
- physical real distance of proxies/en Web sites
- wire distance of proxies/en Web sites
- programming language used
- ISP/country/state/county policies (which are sovern BTW (so you have to comply to laws or at least circomvent them in an undetectable way) the later (right) more strigent)
- react on CPU signals
The program would react to both remotely and locally instigated events. That is for example the arrival of a new email would trigger the logging,analisys (word file) and reply from remote,
while a predefined timely event (today is 24th of December,time to send "Mery Christmas wishes") would be local instigated.
The long term data stage would me use of databases,directories and files on hardware.
Of coarse the program would have to be made with security in mind. (encryption,backup,circonvention, ect.), and be re-entrant when a sub-program halts du to error.
The program would also represent interlink between forum site,that is for exmaple what is forum A relation to forum B.

The exact low level global and general structure of a forum site is given an another spec (forum_spec_low_level). Other operations may include (but not limited to) sorting (by key) from
(a defined range), adjusting (data formats (differing amongst operating System (OS),dates,location, ect..),time (differing amongst timezones),language, measurement units (US/metric),
URL formats),searching,analysing data,reactime to network/computer/CPU events ect,ect.

That said (the above),this is a COMPLEX program that suits for EXPIRIANCED programmers and is VERY CHALLENGING.
The knowlege of programming language,network protocols,databases,Operating Systems (OS),hardware is a MUST.
A further spec (forum_spec_low_level) gives every detail to interested programmers.

how to dynamically set the CRecordset Fieldtype ?

Hi
the problem i am having is that when i try to get
Code:
short nFields = rs.GetODBCFieldCount();
                        CDBVariant b= new CDBVariant[nFields];
                        for (short index = 0; index < nFields; index++)
                        {
                                rs.GetFieldValue(index, b[index],DEFAULT_FIELD_TYPE);               
                        }
now i want to change the DEFAULT_FIELD_TYPE dynamically
so i fount out that using
CODBCFieldInfo c;
rs.GetODBCFieldInfo(index, c);
SQL_C_CHAR h = c.m_nSQLType; //this is not correct but i need a SQL_C_CHAR to pass in rs.GetFieldValue(,,here);

so how i can dynamically pass the nFieldType becuase if i dont the GetFieldValue get the value in binary which is not correct

the data i am getting is in this form
Quote:
1 jack 23 2015-12-13
2 ryan 23 2015-12-13
3 jhon 23 2015-12-13
so the GetFieldValue (,,nFieldType ) should change but its not changing
i get the first field ok mean i get the 1 correctly but the name is in binary and other 2 values also in binary

nFieldType SQL_C_CHAR table is link below
https://msdn.microsoft.com/en-us/library/5f8k59f9.aspx

if i go manually then
for first row

Code:
CDBVariant id;
CDBVariant name;
CDBVariant age;
CDBVariant date;
 rs.GetFieldValue(short(0), id,      SQL_C_SLONG);
 rs.GetFieldValue(short(1), name, SQL_C_CHAR);
 rs.GetFieldValue(short(2), age,    SQL_C_SLONG);
 rs.GetFieldValue(short(3), date,  SQL_C_TIMESTAMP);
but i want to change rs.GetFieldValue(short(0), id,SQL_C_SLONG); this dynamically

I am making some ids for the tiles of a grid in a game.
And I want to make a unit test module for regression testing.
But the data sometimes differ, I want to say test, when I give the unit test an id
it returns me with some neighbouring tiles.
However, when I change the program, all the ids change/shift up and down,
What are the general techniques to make test data consistent and predictable?

Should I make sure the bottom-up approach is used, so that I test lowest layer first.
And don't worry about it after gurranteeing it is correct.

Preprocessor string (with space characters)

I've just noticed this problem with MSVC8 (I'm not sure if it also affects later versions...)

Suppose I open my project settings and navigate to Configuration Properties->C/C++->Preprocessor. I then add the following pre-processor definition;-

Code:
SOME_STRING="\"Hello World\""
Believe it or not, this stops the program from compiling! If I try to compile any source file in that project I see the following compiler error:-

Code:
c1xx : fatal error C1083: Cannot open source file: 'World"': Invalid argument
It makes no difference whether my pre-processor string ever gets used anywhere. The mere presence of a pre-processor string containing a space character causes the above compiler error. If I remove the space, everything compiles fine.

I'm totally baffled... Does this make sense to anyone here..?

Hi Guys, I have problem width draw two flowcharts. Please help me draw this flowcharts.Thanks!!!!

First:

Code:
for (i = j = n - 1; i >= 0; --i)
        {
                if (arr[i] != 0)
                {
                        if (i != j)
                                arr[j] = arr[i];
                        --j;
                }
        }
        for (i = 0; i <= j; i++)
                arr[i] = 0;

        cout << endl;
        cout << "New array: " << endl;
        for (i = 0; i < n; i++)
        {
                cout << arr[i] << " ";
        }

and second code:
Code:
mult = 1;
        for (int i = 0; i < n; i++)
        {
                for (int j = 0; j < m; j++)
                {
                        if (pp[i][j] < 0)
                                mult *= pp[i][j];
                        else
                                mult = 0;
                }
                if (mult)
                {
                        cout << "Sum: " << mult;

std::map::at() versus std::map::find()

December 28, 2015, 12:15 pm

Using VC8 I'm trying to compile a program originally written for the gcc compiler. At one point it uses std::map::at(). MSVC does support std::map::at() but it wasn't introduced until VC10. So the nearest thing I have available is std::map::find(). This latter function returns an iterator (which I'd need to de-reference). But I can't quite figure out what std::map::at() returns. Does it also return an iterator or does it already de-reference it to return a value?

I want to look at some crash dumps but can't due to mismatched dates between executibles and pdb files.

Apparently there was some data lost at some point and the restore software must have striped a bunch of restored files with the same date.

My issue is I have found some software that would fix possibly an older version of pdb...pdb7.0.

Is there a table that shows what Versions of Visual Studio used which version of PDB?

Anybody have any ideas here?

Your help is really appreciated.

How to close the main application by clicking on the console?

December 28, 2015, 7:47 pm

I spawned a console from the main application as a log window.
But when I clicked on the x of the main app, the application just won't stop execution.
When I clicked on the x of the console, it does stop, but memory leak remains.
I rechecked and discovered the destructor of the main application never got called
when I clicked on the close button of the console window.
how do I make sure I call on that no matter which window I close from?

I open a console like this

Code:
#include "CMyApp.h"
#include <crtdbg.h>

FILE* consoleWin = NULL;
 

INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR, INT )
{
        // check for memory leak
        int flag = _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG);
        flag |= _CRTDBG_LEAK_CHECK_DF;
        _CrtSetDbgFlag(flag);

       
        AllocConsole();
        consoleWin = freopen("CONOUT$", "w", stdout);
       

        CMyApp SimApp;       
       
        if (!SimApp.Create(hInst))
                return false;

        if (!SimApp.Run())
                return false;
       
        fclose(consoleWin);
       
       
        return 0;
}

LRESULT CALLBACK CSimApplication::WinProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
        switch (uMsg)
        {
        case WM_CLOSE:               
        case WM_DESTROY:
                PostQuitMessage(0);
                break;
        case WM_KEYDOWN:
                switch (wParam)
                {
                case VK_F11: // error on F12???
                        PostQuitMessage(0);
                        break;
                }
                break;
        case WM_SIZE:
                // Check to see if we are losing our window...
                if (wParam == SIZE_MAXHIDE || wParam == SIZE_MINIMIZED)
                        CSimApplication::m_pGameApp->SetGameActive(false);
                else
                        CSimApplication::m_pGameApp->SetGameActive(true);
                break;
        case WM_ACTIVATE:
                if (LOWORD(wParam) == WA_INACTIVE)
                        CSimApplication::m_pGameApp->SetGameActive(false);
                else if (LOWORD(wParam) == WA_ACTIVE || LOWORD(wParam) == WA_CLICKACTIVE)
                        CSimApplication::m_pGameApp->SetGameActive(true);
                break;
        case WM_ENTERSIZEMOVE:
                CSimApplication::m_pGameApp->SetGameActive(false);
                break;
        case WM_EXITSIZEMOVE:
                CSimApplication::m_pGameApp->SetGameActive(true);
                break;
        default:
                return DefWindowProc(hwnd, uMsg, wParam, lParam);
        }
        return 0;
}
After that, there is a log singleton to hold onto the log messages.
Thanks

List iterator is not incrementable

On the line
Code:
for (std::list<MSG_Object*>::iterator i = m_delayedMessages.begin(); i != m_delayedMessages.end(); ++i)
{
The i variable has become 0xcdcdcdcdcd, It doesn't happen immediately, it accumulates to about 18 messages in the start, and gradually delivered everything until there were 4 messages left. I look it up in the web which says it is an uninitialized variable of some sort. I didn't write this code, so I am not sure why that happens.
It seems to me that i has been initialized on this line, why the error still pops up?

The error happens also in the original program, I think it was written for VS9 or something, now I am using
VS2013 community.

Hotkeys in C++ app suddenly stop working

Hi. We have a problem with our software that we’re struggling to fix. The app is a MFC C++ media player for Windows, the FTW Transcriber: http://www.theftwtranscriber.com/

Program users can use hotkeys to play files, including stop, rewind and forward functions. However, users who upgrade to Windows 10 sometimes experience problems with the hotkeys. They work for a while and then suddenly stop, and we don’t know why. Restarting the PC or reinstalling the software makes the hotkeys work for a while, but then they stop again.

While the hotkeys are working, F1 plays the file, as it should. After they stop working, F1 opens help. In other words, it appears that Windows 10 is stealing the keyboard input from our program. But it's strange that everything works fine at first but then stops for no obvious reason.

Most of the DEFAULT hotkeys are "F" keys, but the software allows them to be remapped to other keys, but they still don't work even after remapping. Any ideas why?!

Please note our question is not why the hotkeys don’t work – the question is why they DO work, and then STOP working.

Thanks!
