I guess i'll just have to do it in stdafx.cpp and stdafx.h., thanx 
|
|

|

Well, you can do it either way, but doing it in a class is definately better, and no harder.

I've placed the struct on stdafx.cpp then the extern part on stdafx.h. But 'undeclared identifier' error still occurs
|
|
|
|
|
oh.. undeclared identifier is no longer the error. The error now is at the stdafx.h. I guess I've placed it in the wrong area. Where am I exactly allowed to place the externs? Sorry for the disturbance

Hi, CPians!
Problem: I gonna be in charge of my local 'POLICE' to write an application which is able to recognise speech(human voice) and handwriting of my native language and local peoples. 
Please, Help me in:
I have not any idea of the required process.(Speech recognition,image processing,... )
-Do I accept it or not?<br />
-How many days, Months, or years!! it might take?<br />
-Where can I find any links or helps on this topic?
Thank you so much in advanced.
Help me please. All in front of me is darkness now, I need a light of information and knowledge.
Any, any help would be appreciated.

Great....

I think we both know the answer. Lets review the facts:
1. You don't know how to do the job
2. Products that do this cost a lot of money ( therefore are not trivial )
3. The police have guns.

days ? LOL

Google, I guess, but I sure wouldn't take this job. I've taken jobs where I had no idea how to do something, but they were SPECIFIC image processing tasks, an area I am broadly familiar with, and I'd found papers describing different approaches to the problem, so it was a calculated risk. What you're suggesting to do sounds more like madness.

Thank you Mr.Christian Graus.
But Some notes:
-First version will need just to be able to compare two voices saying the same sentence.
-Some years ago I was asked to write my first application which had to convert some data from their old format(in a DOS app.) to new data and insert them into SQL Server. I was a begginer in C++ (now think about VC++ ) but I accepted it(another maddness  ) and it was all success
Will this situation not tobe the same?

Well! you are right.
look at my first resault of a google
Handwriting recognition has always been tough problem. It takes years to come to a commercially valuable result in this area - years of research, ...
Why don't think about my university projects, instead

No, because the other problem is well documented and commonly done. There were a lot more sources of information available to you, and it was the sort of stuff that a computer does easily, it was not a complex coding task.
Amazon appears to have numerous books on speech recognition, most of which come with toolkits. They are all pretty expensive, but I'd buy a couple and read them before committing to a job like this.

Thank you.
I modified last message!
Excuseme, I know it's stupid but, I think thhis sentence is wrong, isn't it?(Will this situation not tobe the same?) could you please tell me the true one? (I'm not english!)

I call projects like this research projects. 
First, if you have never done and speech recognition, do as Christian suggested and go buy a book.
Better yet (BFO attack), go see if you can buy something off the shelf and integrate it. I doubt your local police department has the resources to fund a project like this - sounds like to me they have no idea what they are even requesting.
A little story... I used to work for a telephony company that had a voice activated product feature - thus, we needed some semblance of speech recognition. One of the developers working on the project was Chinese. No matter how hard she tried, she could not get the VR to respond to her accent. This is just one of the technical hurdles you will need to overcome. You might be able to do it with an existing product. Develop your own? Unlikely.
chg (my opinion only).
Oh, handwriting is just as difficult. One other oh - I would bid this project time and materials only. Too much risk for a fixed price.

Hi.
I have an application, (MFC application using VC++ 6.0), runing in all the windows PC OS, (from Windows 98 to Windows XP), and now, I want to run that program in a Palm using Windows CE, (3.0 or 5.0).
The question is: can I migrate that program to windows ce keeping the main development in Visual C++?.
I.E -> I'm using many MFC arrays like CByteArray, CWordArray, CObjetArray, etc.
I'm using serialization.
And many things of MFC., (Dialogs Class and Windows Class, etc)
All this will work in Windows CE 3.0 or 5.0??
Or should I make an all new application using .NET??
Thank you in advance.
Demian.

Demian - usually, it's best to start on Windows CE and go the other way. I've just spent the last 2 years of my life on a Windows CE project. It is still going strong..... It's pure MFC with activeX, dialogs, etc. My experience is that *most*, not all of the desktop will run on Windows CE.
Question 1: Usually, Windows CE devices have much, much smaller screen real-estate. How might this impact your application?
OS Version: At a minimum, 4.2 (MS calls it .net) or just go to 5.0.
As I said above, most will run in CE, but the compiler will let you know what is missing. Serialization has it's limitations. Also watch out for unicode issues.
New app - that all depends... I'd need to know more about what your desktop app does....
Let me know.

Thank you very much Gilley.
But, one more thing. For continue working with VC++ 6.0 and building new applications for Windows CE, should I use Microsoft® eMbedded Visual Tools 3.0 (or later) isn't?
That's what I must to add to my Visual Studio. Or what else?
Thank you.
Demian.

Heh, heh - not laughing at you, just remembering much angst trying to figure out how to do this. The general answer to your question depends on what you want to do philosophically. In any event, you will need to install Embedded Visual C++, a completely separate environment from VS. Version 3.0 is very old, I use 4.0. Don't forget that you will need an SDK. Follow up with any questions...
Options:
- you can use the same code base, pulling it from version control. If you do this, then the
embedded VC++ and VC++ areas need not be the same.
- if you want combined projects / don't use version control, then you tend to toss everything
into the same folder. Since the VS project already exists, you simply create an EVC++ project
in the same location (VS workspace files are .dsw, EVC++ are .vcw), then add the source files
to it.
WARNING! I've only done this with an activeX control project, so try this on a small project first and make backups.
Let me know if I can answer any other questions....

Hello All, I have an application that runs without error on my own system. Even in release mode  . However, when i run the application on other systems, my app reports to me that it was undable to aquire a crypt context (CryptAcquireContext) due to an invalid param.
This code is called in a simple C worker thread. Any Ideas?
<br />
UINT stringHash(byte* message, char* hash){<br />
DWORD hashLen = 16;<br />
<br />
HCRYPTPROV hCryptProv;<br />
HCRYPTHASH hHash;<br />
<br />
<br />
ZeroMemory(&hCryptProv, sizeof(hCryptProv));<br />
ZeroMemory(&hHash,sizeof(hHash));<br />
<br />
BYTE hashedBytes[16];<br />
<br />
<br />
if (!CryptAcquireContext(&hCryptProv, NULL, MS_ENHANCED_PROV, PROV_RSA_FULL, 0)){<br />
CryptReleaseContext(hCryptProv,0);<br />
return GetLastError();<br />
}<br />
<br />
...<br />

You are trying to acquire the handle to key container "Microsoft Enhanced
Cryptographic Provider " with the parameter MS_ENHANCED_PROV . The 9x
system may not be having this key container with it. So try to get handle to
some other key container. Or use NULL to get the handle to the default key
container.
If you don't like defaults !! try MS_DEF_PROV which is there with all window
flavors i guess...

Good afternoon,
in MFC'S wincore.cpp line 882......where is the P come from? looks like should be pMap->LookupPermanent(m_hWnd)) or pMap->LookupTemporary(m_hWnd)), but they were both error out in watch window....
CObject* p;
ASSERT((p = pMap->LookupPermanent(m_hWnd)) != NULL ||
(p = pMap->LookupTemporary(m_hWnd)) != NULL);
ASSERT((CWnd*)p == this); // must be us
I got assertin failed on last line, but I don't really understand why is it happening, the last part form my app is going to CDialog::OnOK();
"Many ASSERTs can occur when objects are created in the context of one module or thread state, and used or destructed in another. "......what is this really mean?
|

Firstly, in release mode, your ASSERT part will not be executed. Thus, LookupPermanent and LookupTemporary will not be called. Would it affect your program? If so, use VERIFY.
valerie99 wrote:
CObject* p;
ASSERT((p = pMap->LookupPermanent(m_hWnd)) != NULL ||
(p = pMap->LookupTemporary(m_hWnd)) != NULL);
If LookupPermanent returns non-null and LookupTemporary returns null, the assertion will not occur. In this case, the next ASSERT will fail.

Thank you, Weiye...
"If LookupPermanent returns non-null and LookupTemporary returns null, the assertion will not occur", I just checked, this is absolutely right, but why is "the next ASSERT will fail. "
what happened is just like you said, but I don't understand why is it happening, when the hash table on LookupTemporary is empty....P will not point to the same address as this?
this is part of MFC's code, my applitaion that using this code is like this:
UINT ThreadFalling(LPVOID pParam)
{
CUsocDlg* pDlg=(CUsocDlg*) pParam;
pDlg->IsThreadRunning=true;
pDlg->Process();
return 0;
}
