So I created a timer that executes GetExitCodeThread(GetCurrentThread(),&TEC).
How can I retrieve the error code stored in TEC.
Am I calling the GetExitCodeThread in an appropriate position or have I misplaced the function.

Call the function from the main thread and not from within the thread.
Pass the handle of the thread that CreateThread returned as the first parameter.
The exit code returned is just a number that you can either print to the screen, show in a message box or compare using an if statement.

What are the differences between _beginthread and CreateThread?
|
|
|
|
|
They are implemented by different libraries.
CreateThread is the Windows user mode API for creating threads.
_beginthread is a C-runtime implementation.
_beginthread internally calls CreateThread.
Both functions return the handle to the newly created thread.
So you can use either one.

Since this is a Win32 app their is no easy way to check like in a Console app.
But I did a nice little workaround, launching a timer that checks for the thread error.
The thread doesn't close, but it seems to freeze.
Returning ERROR_NO_MORE_ITEMS (0x103) during that period.
Then it completes successfully returning 0x0 for ERROR_SUCCESS.

Do you know a way to lookup up what the cause of ERROR_NO_MORE_ITEMS is?
|
|
|
|
|
Is this returned by GetExitCodeThread?
|
|
|
|

No! Like I said before, because it's GUI app.
Created a timer event that monitors how the process is doing.
Those URLs I posted are currently causing the thread to freeze after the receiving loop finishes.
During that the timer checks the thread error state, receiving ERROR_NO_MORE_ITEMS.
After 3-4 minutes have elapsed the thread finishes, the timer event returns thread has exited successfully.
Do you think increasing thread priority would do the trick. Or would it hurt my application?
I tried looking up ERROR_NO_MORE_ITEMS for details, but was unsuccessful however the only thing I managed to dig up was the Windows Error Codes.

i got a C code for FIR from the nuhertz filter software, am not sure if am using it correctly. i implemented it as shown below and also did a manual calculation using coeffiecients and the answers do not match at all.instead of reducing the amplitude, its the other way round. am not sure if anyone has used this before
int setic ;
float initvar;
for (int i = 0;i<=146; i++)
{
for(int z = 0;z<=8;z++)
{
if (z == 0)
{
setic = 1;
initvar = raw_data[i][1];
}
else
{
setic = 2;
}
results2[i][1] = DigFil_fir(raw_data[i][1],initvar,setic) ;
}
}
float DigFil_fir(float invar,float initval, int setic)
{
float sumnum; int i;
static float delay[9] = {0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0};
static float znum[9] = {
6.205e-02,9.553e-02,.1241,.1433,.1501,.1433,.1241,9.553e-02,6.205e-02
};
if (setic==1){
for (i=0;i<=8;i++) delay[i] = 1.0*initval;
return initval;
}
else{
sumnum=0.0;
for (i=0;i<=7;i++){
delay[i] = delay[i+1];
sumnum += delay[i]*znum[i];
}
delay[8] = invar;
sumnum += delay[8]*znum[8];
return sumnum;
}
}

Hi,
The variable 'initvar' is declared within the 'if' code, therefore it would not be available to pass to the function 'DigFil_fir'. This code should not compile, unless you have another 'initvar' declared, if so this is your problem.
Hope this helps, 
Ali

 If you want people to help you with your code and you paste it in a message for them to check, I think you should make sure that it is the code you are testing ..... putting your original post right might be nice too, if you want more help .....
Just sayin ......

The thing that jumps out at me is the index range for the first for loop 1 to 146? With C? 0 to 145 would sound more idiomatically correct?
But it's very difficult to tell without a little more code...

So have you stepped through the code using the debugger to see what the values are?

Hi,
I have created a dialog based application in visual studio 2010 and I have added a CSplitButton Control to my dialog through resource editor, also I have made a menu in resource editorwith the ID of IDR_MENU_BUTTON_FILE and a sud menu after all, my code looks like the following code:
BOOL CMyDialogDlg::OnInitDialog()
{
CSplitButton* pCtrlSpiltBtn = (CSplitButton*)this->GetDlgItem(IDC_SPLITBUTTON1);
pCtrlSpiltBtn ->SetDropDownMenu(IDR_MENU_BUTTON_FILE, 0);
}
however the pCtrlSpiltBtn get initialized correctly and every thing is OK. but
pCtrlSpiltBtn ->SetDropDownMenu(IDR_MENU_BUTTON_FILE, 0);
fails when I trace the case I found that this line call the following methods of MFC classes.
void CSplitButton::SetDropDownMenu(UINT nMenuId, UINT nSubMenuId)
{
Cleanup();
m_nMenuId = nMenuId;
m_nSubMenuId = nSubMenuId;
}
void CSplitButton::SetDropDownMenu(CMenu* pMenu)
{
Cleanup();
m_pMenu = pMenu;
}
void CSplitButton::Cleanup()
{
if (m_pMenu)
{
delete m_pMenu;
}
m_pMenu = NULL;
m_nMenuId = (UINT)-1;
m_nSubMenuId = (UINT)-1;
}
and the m_pMenu pointer is always initialized and while the line
delete m_pMenu;
get executed all the application ruining fails.
Please help me solve the case, what should I do?

A separate margin? Separate from what?

There is a 3rd lib only accept char* filename e.g.
3rdlib_func_name(char* file_name) . Every things get wrong when I provide a filename in Chinese or Japanese.
Is there any way to make this lib open UNICODE filename? The program is running on Windows.
Thanks for your reply.

Only by changing its source code. You will have to go to the suppliers of the library to get it changed if you do not have the source.
It's time for a new signature.

I think so.
In theory, char* cant only be used to point to a UTF8 UNICODE string, however, you cannot give a UTF8 filename to fopen or some other file functions. But if I transfer this UNICODE filename to char* using CP_ACP, some of the characters cannot be changed.

Exactly right, which is why all software suppliers should be providing full Unicode support. I think you need to talk to the supplier of the library and get them to change it. You may also note that _wfopen is the Unicode version of the file open function, so there is no problem with Unicode file names.
