What did you think you were going to get? That's what a binary file is.

Open it in any hex reader (or visual studio -- do file->open and select "Open As" = binary).

I hope you are getting some junk value... in file_array for non text files..
if so, its obvious... because you are trying to view char value which is not char...
But for text files the data are in the form of char

Is there a GetRedraw function or message?

I frequently use SetRedraw(FALSE) -> do drawing stuff -> SetRedraw(TRUE), but I sometimes have an outer drawing loop that does this, which calls, as part of the drawing, something else that also turns off/on redrawing, thus overriding the 'outer' loop's redraw flag. I have wondered if anyone knows of any way of determining the current value of the redraw flag for a window?

hello everyone,
I need to assign my App to some protocol like this:
I am on a website that contains <A HREF="someprotocol://someaddr">
it will load the program and pass this as the command line

This is just a guess, but try merging the following into your registry:

[HKEY_CLASSES_ROOT\someprotocol\shell\open\command]
@="\"C:\\Program Files\\somefolder\\someprog.exe\" %1"

You're not so far from the truth
here's result maybe someone needed:
bool SetMoniker()
{

CString url = _T("your protocol");
CString def = _T("URL:someproto"); //can change after URL:

TCHAR app_path[_MAX_PATH+1]=_T("\0");
GetModuleFileName(NULL,app_path,_MAX_PATH);

CString icon(app_path);
icon += _T(",0");
CString command(app_path);
command = _T("\"") + command + _T("\"");
command += _T(" \"%1\"");

HKEY key;
if (ERROR_SUCCESS == RegCreateKeyEx(HKEY_CLASSES_ROOT,_T("someproto"),0,0,REG_OPTION_NON_VOLATILE,KEY_WRITE,0,&key,0))
{
RegSetValueEx(key,_T("URL Protocol"),0,REG_SZ,(BYTE*)url.GetString(),(DWORD)( url.GetLength()*sizeof (TCHAR)) );
RegSetValueEx(key,NULL,0,REG_SZ,(BYTE*)def.GetString(),(DWORD)( def.GetLength()*sizeof (TCHAR)) );
HKEY icon_key;
if( ERROR_SUCCESS == RegCreateKeyEx(key,_T("DefaultIcon"),0,0,REG_OPTION_NON_VOLATILE,KEY_WRITE,0,&icon_key,0))
{
RegSetValueEx(icon_key,NULL,0,REG_SZ,(BYTE*)icon.GetString(),(DWORD)( icon.GetLength()*sizeof (TCHAR)) );
RegCloseKey(icon_key);
}

HKEY com;
if( ERROR_SUCCESS == RegCreateKeyEx(key,_T("shell\\open\\command"),0,0,REG_OPTION_NON_VOLATILE,KEY_WRITE,0,&com,0))
{
RegSetValueEx(com,NULL,0,REG_SZ,(BYTE*)command.GetString(),(DWORD)( command.GetLength()*sizeof (TCHAR)));
RegCloseKey(com);
}

RegCloseKey(key);
return true;

return false;

Hello i'm using a neverending loop to read informations from the COM but the problem is that the reading process blocks my aplication. Not to listen to the COM all the time is not an option. What should I do to use the aplication in this time?

Re: Blocking

Can you put the reading process in a thread?

Why don't you put this loop inside a thread function to read the COM port>?if you do so you can keep on reading the COM port in the thread and leave your main application's thread working.

Create a worker thread and put your

<br />
do<br />
{<br />
//your COM reading code<br />
}while;<br />

loop inside the Thread function.

Re: Blocking

simple... Follow these steps :
you have a function. ReadCOM(). You dont want this to block your application.

declare these in your header may be COMPROG.h

<br />
//COMPROG.h<br />
static UINT MyThread(LPVOID lp);<br />
void ReadCOM();<br />

in the implementation,

COMPROG.cpp<br />
AfxBeginThread(MyThread,this);// Your call to start the thread.<br />

Your Thread:

<br />
UINT MyThread(LPVOID lp)<br />
{<br />
 CCOMPROG* obj = (CCOMPROG*)lp; //To access the  ReadCOM function, or you can pass any function, with using the void pointer.<br />
 obj->ReadCOM(); <br />
}<br />

Your Fcuntion:

<br />
void ReadCom()<br />
{<br />
 do<br />
  {<br />
   //Your Code to read COM<br />
  }while(x==true);//your condition<br />
}<br />

Thanks a lot I folowed your code but ended up with the folowing error message : error C4716: 'CMina_sView::MyThread' : must return a value; i tryed to insert a return 0 or return TRUE but that wasn't much of a help as I got the same result: program blocked. so??!?

Re: Blocking

Eytukan25-Jul-06 1:28

it has a return type of UINT
so do this, I missed it Frown | :(

return(0); Now it should work. Otherwise you tell me. we'll kill it.

also that , when you put your "readCOM()" function inside the class,

implement it with your class(CCOMPROG) refernce like void CCOMPROG::readCOM()

I'm afraid someone will have to get killed. Smile | :)

) Let me tell you how i modified your code:
1) I use an OnListenComm() function that is as the name tells us: a function auto-defined by VC++ that handles the code when you click on listencom button.
2)The modifications:

static UINT MyThread(LPVOID lp);
afx_msg void OnListenCom1();

AfxBeginThread(MyThread,this);// Where should i put this???????

UINT CMina_sView::MyThread(LPVOID lp)
{
CMina_sView* obj = (CMina_sView*)lp; //To access the ReadCOM function, or you can pass any function, with using the void pointer.
obj->OnListenCom1();
return 0;
}

Re: Blocking

Eytukan25-Jul-06 3:44

It depends on when you want to start the thread. For example, you have CButton , If you wanna start listening to COM on the click of it, put the AfxBeginThread inside the OnClick Event of the CButton. You can do that anywhere.
