Is it posible to draw on two monitors, perfect synchronously ? I had taked from here[^] an good example of how can I handle two monitors, but if I want to draw something on them, the drawing is no synchronously ... could you guide me in order to do that ?
Thank you.

|
|
|
|
Even with two threads running it is impossible to guarantee exact synchronous actions.
|
|
|
|
|
And how would you synchronize the hardware refresh period? I would drop this idea.
|
|
|
|

I didn't put this problem, my goal is to draw the same image, on two monitors, in the same time, at leat to begin to draw the same image in the same time. Any idea will be welcomed.

Hi,
I am developing a MFC application on Windows 8.1 using VS-2005.
Requirement is to customize Folder Explorer for a specific purpose. I want to create own pidl for folder and its contents.
When I will open a particular folder, application's should inherit Win-8 Windows explorer.
I want to set customized icon for folder on top left corner(On Win-8) and at the root of address bar.
I am using GetBindToObject, GetUIObjectOf, CreateViewObject, GetIconLocation and Extract method in ShellFolderImpl class. Please give me some sample source code or idea to do that. I have already studied URL - [http://msdn.microsoft.com/en-us/library/windows/desktop/cc144093%28v=vs.85%29.aspx ] but it is not working.
This method is in ShellFolderImpl class
BindToObject, CreateViewObject, etc functions are working correctly.......
Icon index and Icon is loaded correctly. bcz I saved created icon from Extract method.
But emplty icon is placed at specified place on folder as given in above image.
1. IExtractIcon interface is called from GetUIObjectOf method correctly.
2. GetIconLocation method gives correct output Index for Icon.
3. Extract function gives correct output for hIcon.
But problem is that Icon assigned to displayed was not correctly displayed at AddressBar and Caption Bar(Top-left corner).
Currently, Icon is displayed on AddressBar and Caption Bar(Top-left corner) was empty file icon.
when I set :
HRESULT ExtIcon::ExtractImpl(UINT nIconIndex, HICON* phiconLarge, HICON* phiconSmall)
{
phiconLarge = NULL;
phiconSmall= NULL;
}
I got folder icon on the AddressBar and Caption Bar.

Dear all:
I implement a application, when I get a touch data from WM_INPUT and touch count more than previous, it will play sound, My code show as below:
void CTouchSoundTrayDlg::OnRawInput(UINT nInputCode, HRAWINPUT hRawInput)
{
UINT data_size = 0;
BOOL bGot = FALSE;
GetRawInputData(hRawInput, RID_INPUT, NULL, &data_size, sizeof(RAWINPUTHEADER));
vector<BYTE> data;
data.resize (data_size);
if(GetRawInputData (hRawInput, RID_INPUT, &data [0], &data_size, sizeof(RAWINPUTHEADER))!=data_size)
{
}
RAWINPUT* raw = (RAWINPUT*)(&data [0]);
if (raw->header.dwType == RIM_TYPEHID)
{
RID_DEVICE_INFO device_info;
UINT info_size = sizeof(RIDI_DEVICEINFO);
GetRawInputDeviceInfo ( raw->header.hDevice, RIDI_DEVICEINFO, (LPVOID)&device_info,&info_size);
if(device_info.hid.dwVendorId = VENDER_ID)
{
g_CurFrameTime = GetTickCount64();
if(g_CurFrameTime - g_PreFrameTime > 30)
{
g_PreUsedSize = 0;
g_CurUsedSize = 0;
}
g_PreFrameTime = g_CurFrameTime;
DigitizerData* result = (DigitizerData*)(raw->data.hid.bRawData);
g_CurUsedSize = result->active_touch_count;
if(g_CurUsedSize <= 5)
{
if(g_PreUsedSize < g_CurUsedSize)
{
PlaySound(m_WavPath, NULL, SND_FILENAME|SND_ASYNC );
}
bGot = TRUE;
}
if(bGot)
{
g_PreUsedSize = g_CurUsedSize;
}
}
}
Default();
}
My question is
when I touch, it will play sound, and the using memory in task manager will be add, When play music is finish, the using memory is still, will not free
,why?
I try to disable the playSound api in my code, and the using memory is stable.
Thank your help, Victor

|

I would assume that data structures are initialized to play the sound, and then the data structures are kept for the next sound to play.
The difficult we do right away...
...the impossible takes slightly longer.

Hi,
I am trying to rewrite an old VC++ wrapper class around MS Word Automation - it used to use *.tli and *.tlh files, but now MS recommends just using the *.h files which get generated. So, that is another level of complexity.
So, I got so far, now I am wondering what to do next.
Here are some code snips, the real code obviously has error correction etc., so here is what I have so far;
IDispatch *pWordInst;
CApplication *pWordApp;
CDocument0 *pDoc;
IUnknown *pUnknown;
HRESULT res = CoInitialize(NULL);
CLSID clsid;
HRESULT hr = CLSIDFromProgID(L"Word.Application", &clsid);
hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch, (void **)&pWordInst);
pUnknown = NULL;
REFIID iid2 = __uuidof(IUnknown);
hr = pWordInst->QueryInterface(iid2, (void **)&pUnknown);
So, now I need to get the Application and Document objects (assuming that this code creates a new document as it used to).
I am guessing I need a getApplication() but what MS class do I use for that?
Once I have the Application, then I can get the Document, presumably with a get_Documents() or get_ActiveDocument()?.
After that I guess it will run like my older version used to.
Any help and advice would be great.
Many Thanks,
Bryan.

I've always done it like:
_Application app;
Documents docs;
_Document doc;
if (app.CreateDispatch("Word.Application") == TRUE)
{
docs = app.GetDocuments();
doc = docs.Open(COleVariant(strFileName), ...);
docs.Close(vtFalse, vtOptional, vtOptional);
app.Quit(vtOptional, vtOptional, vtOptional);
}Not sure if that helps you or not.

We were given a task to use lists and iterators. We were supposed to make them from scratch. I'm done with that. The problems that I'm having are as following:
1. I'm not able to access the list made of Course datatype which is present in each Student instance. Does this mean I need to make an iterator for that course list inside the student class?
2. Similarly since I don't have direct access to The course list so I added the course into the Student list through the student objects not through the iterator. How can I do it through the iterator?
3. Printing of a particular student and his courses is not happening as my iterator made for student only prints out the students, not the courses present in their courselist. How to do that?

IMO, You should insert into a list, not in to an iterator.
The iterator is (only) used for traversing the list; have a look at what STL does, the container is std::vector and its iterator is std::vector::iterator.
Ok, to answer the questions:
1. Yes, there should be a method (private) inside the Student class to iterator over the course.
2. the printCourse method should iterator over the courseList list.
3. the studentList should not have a "printData"; just iterate over over the Student and call printCourse for each student in the list.
...
YMMV
Good luck.
Max.
I'd rather be phishing!

I have a console application which calculates using formulas based on the inputs it is receiving every cycle in a particular frequency and gives dynamic output values based on its input variables and constants and so on. In short its a real time application.
This application was initially developed in Visual Studio 6.0 as c++ console application. Recently we converted it to Visual Studio 2008.
It was working fine in VS 6.0. But after conversion, some of the values shows -1.#J which seems like infinite values.
When I observed, it seems like certain calculations may result in divide by 0 or complex values like square root of a negative number and these values should show the value as -1.#J.
But I wonder how there was no such values in VS6.0 whereas VS2008 shows these junk values.
Please suggest me some ways of preventing it.

Firstly, please indent your code properly and use <pre> tags around it so that it is readable, like:
for(J = Esim->COMPBEG; J <= Esim->COMPEND; J++)
{
Esim->SCOMP[J][OV] = Esim->SCOMP[J][OV]/SYCOMP;
Esim->NXDER[J][FN] = (Fl*Esim->SCOMP[J][IL]+Fv*Esim->SCOMP[J][IV] -(Fv)*Esim->NXS[J][FN]
-(Fl)*Esim->NXS[J][FN])/(10 + MAXI(Fp-(*Vapor),100.0)
*Esim->STPSIZEH/10000);
Esim->NXS[J][FN] = EULER( N, K, TYPE, DER, MAX, MIN, FLAG);
SXCOMP = SXCOMP + Esim->NXS[J][FN];
}
Secondly, please indicate exactly where the error occurs, and show the values of the inputs at the time.

You don't want to do that, you want to avoid device by zero period. If you don't know why, go back to school.

One possible reason of many is that in the original (vc++ 6) structured exception handling was enabled and now it isn't. This would mean that divide by 0 exceptions were being thrown but not being caught (possibly). Now they are just crashing the program.
Unhandled divide by zero is bad so don't worry about why it did/did not. Just fix the problem now. Structured exception handling is a very good way of doing that.

Hello there,
I am using CDHtmlDialog in my MFC application to create a UI with HTML, CSS & JavaScript.
In my project there's one dialog created from CDHtmlDialog and a corresponding HTML file for that dialog.
Now during run time i want to change the contents of the HTML file.
Not just the HTML part, i want to change the CSS & JavaScript too.
So basically what am trying to do is, change the entire content of the default HTML file.
Is this possible? If yes, how can i do that?
Thanks in advance!

I have a static control area, it is about 4 lines height.
if I only have one string to display, How can I make it horizontal and vertical center?
Thanks

For the horizontal center, use SS_CENTER, there is not vertical center for CStatic ( or Cedit), you will have to do it manually.
I'd rather be phishing!
