Flow is not passing in a worker thread

12-Oct-07 0:57

1. take each unsigned short from the array.

2. take 2 var byte1 and byte2.

3. from each byte observe each of its nibbles.

4. if any nibble is greater than 9 then that element is your victim.

5. simple ,problem solved! Laugh | :laugh:

6. any more doubts? Confused | :confused:

I have made a sdi application, in that i have made a worker thread(in main application class) in that i have used some api's. Now my problem is in some case a api is not passing the flow of control. In this case after 10 seconds i want to display a message and break the thread. I tried to use timer through SetTimer method but it was not applicaple because WM_TIMER message is not present.Now, how to solve this problem? Can anybody help me in this.

Thanks in advance

Hey,

You can use void sleep( long millis ) instead of using timer

do you mean that, your control flow is not coming out of your api?
if that is so, then,
as you said, timer is not working,
you can initiate another thread and do your termination there after 10 seconds.
any more clarifications?

can you explain me this through an example. I am not getting where to start a thread and how to apply your procedure

chandu00411-Oct-07 21:59

11-Oct-07 21:59

say your thread 1 is like this.

thread1<br />
{<br />
....<br />
....<br />
....<br />
....<br />
api1();<br />
....<br />
....<br />
....<br />
}

if you feel that some times your control is not coming out of api1. right?
so, take a global variable,
say flag=0;
before api1, make flag=1;
and after api1 make it 0;
take another thread, say,

thread2()<br />
{<br />
  int counter=0;<br />
  while(1)<br />
<br />
<br />
  {<br />
   Sleep(1000);//1 second<br />
   if(flag==1)<br />
   {<br />
     counter++;<br />
     if(counter>10)<br />
         terminate thread 1.<br />
   }<br />
   if (flag==0)<br />
   {<br />
     counter=0;<br />
   }<br />
 }<br />
}<br />
<br />
}<br />
}

start it just after your main thread creation.

your given code is working fine but now the problem is i am starting various number of same threads together(for example if i have to find html code of 20 websites same thread will be run together for 20 websites and i am synchronising them using critical section). so if i end my 1st thread in 2nd thread all processing will stop at once and i will not get output of left sites....So how to deal with it.

yah, got your problem.
then you must change your architecture, in such a way, that, the timeout monitor thread is not common for all the threads.
so implement as follows.
thread1()//this thread may be having somany instances
{
create thread2();//which monitors the thread 1 for the timeout value.
-------
------
--------
flag=1;
api1;
flag=0;
--------
}
thread2()
{
you try to frame this logic.
}
here, for each thread1, a child thread(thread2) is created, which monitors its parent's(thread1's) timeout, and kills it if it is not responding in a specified timeout, and also terminates itself.

How to support 128 dpi and 192 dpi as well?

Hi,
I'm developing an application that displays for 96 dpi perfectly fine.
But it doesn't get automatically adjusted on an 480 x 640 TFT LCD.
There must be an easy way of including an API that can convert my current program to
support the high dpi without much effort.
I would appreciate if someone can provide a helping hand.

Additional info:
I have extracted some lines of code below from the stdafx.h :

#if defined(WIN32_PLATFORM_PSPC) || defined(WIN32_PLATFORM_WFSP)
#ifndef _DEVICE_RESOLUTION_AWARE
#define _DEVICE_RESOLUTION_AWARE
#endif
#endif

#ifdef _DEVICE_RESOLUTION_AWARE
#include "DeviceResolutionAware.h"
#endif

Whats the Problem?

As a side note, Windows is completely broken and incapable to cope with higher resolution. (fixed-size icons, fixed-size system-font, font rendering works only for 96dpi etc)

Maybe you simply experience the brokenness of Windows here?
Complain to Microsoft and tell them to fix that in Vista2
(and while you're at it, also tell them to drop the DRM forcing people to stay with XP or even W2K)

The image I wish to display on Pocket PC LCD screen, appears in the middle of the screen.
And to be exact it takes up only half of the Pocket PC LCD screen width.

Have you used "Include file to project..."?? Just putting the #include header.h may not be enough.

ummmm.... The only thing that immediately comes to mind is perhaps you haven't included the .cpp or .h files (or whatever types of files you're using) in your project.

Make sure you've included the files and then you shouldn't have any other problems otherwise give me the exact error message and I'll see what I can do.

Good luck and cheers mate,

Michael

Hi,

Thanks For very Quick reply.As u told me to include .h or .cpp files that i have already done it.

And still i am getting that error. And also when i see its (function's)definition than it points to that project also.

I am using the function SetHook(....) in my existing project and this function is in the new added project. And error gives like below......

1>d:\testing_and_download\testing\testrtmp_working\testrtmp\rtmpdesk.cpp(665) : error C3861: 'SetHook': identifier not found

I am using this function in the RTMPDesk.cpp file in that i have included new project's .h file.

And what is the issue of this .lib file??? As i have got reply

Plz reply me.

Thanking u.

Ashish

SetHook( ) is member function or global function.????/

Hi hiru,

In my workspace i have project TestRTMP exist ok.

And i have included another project in the solution VNCHooks. IN this new project I have .cpp file VNCHooks.cpp file in that SetHook() function is available (it is global there is no any class available in this file) . it is declared in the VNCHooks.h file.

And in my Project dependancy window (and in tab of depends on..) i have only one projrct(my orignal) there is new added project available.

Thanks.

The second project will need to be a library. You'll need to reference the appropriate header file in the new project and link against its .lib file. google will help
