How could I judge it, it assume that I have a path like C:\My folder\Myfile\, how to judge if this folder can be written? Note, path may be on a read-only CD or from network with no write privilege, is there a API to complete this function?
I tried CreateFile, while it fail with the error code ERROR_ACCESS_DENIED it is have no write privilege, what I want to know is that if there are other methods to do so?
3ks and best regards.
One day a pretty girl asked me:"Do u think you are handsome?" "I don't think so!".She gave a slap in my face:"Why lying?"...

How about the GetFileAttributes()[^] API?

GetFileAttributes?? I don't think it can work properly. Here I have a path, GetFileAttributes can only get its attribute, how could i know if i can write in the folder. Even the folder is read-only, I can create file in it, right?

Oh yeah, sorry
It seems like checking all the possibilities (security, writable device, etc) would be alot
more work than just checking the return from CreateFile().
Maybe there's an easier API - I don't know what it is.

HI,
I would like to send a scroll message to Other app(like explorer.exe, IE, notepad.exe....) Using Code like this:::SendMessage(hwnd,WM_VSCROLL,SB_LINEDOWN,0);
It succeed in these APP, but when i try to send the message to MS WORD and OPERA, it failed.
Is this a MDI's reason, How can i solve this?
thanks.

worker thread did not survive the release version - MFC
in the debug version it did not clash and ran smooth, and completed the cyclesequence function
but it clashed badly in the release version. cyclesequence function was never completed
sry i am very bad in threading. i have search all over but cannot find the solution
ok here's how my program goes
when the user presses a button called "RUN" , i begin my thread
void COpc_serialDlg::OnRun() <br />
{ <br />
m_th_sequence = AfxBeginThread(th_start_sequence, (LPVOID)this );<br />
m_run.EnableWindow(FALSE);<br />
<br />
}<br />
my thread begins by obtaining information from editboxes and starts a function called CycleSequence
<br />
UINT COpc_serialDlg::th_start_sequence(LPVOID lpvParam)<br />
{<br />
COpc_serialDlg *th_start_receiving = (COpc_serialDlg*)lpvParam;
int times = 0;<br />
CString startstring = "";<br />
CString repeatstring = "";<br />
CString endstring = "";<br />
times = th_start_receiving->GetDlgItemInt(IDC_REPEAT_TIMES1);<br />
th_start_receiving->GetDlgItemText(IDC_STARTKEY1 , *startstring);<br />
th_start_receiving->GetDlgItemText(IDC_REPEAT1 , *repeatstring);<br />
th_start_receiving->GetDlgItemText(IDC_ENDKEY1 , *endstring);<br />
th_start_receiving->CycleSequence(times, *startstring, *repeatstring, *endstring);<br />
th_start_receiving->PrintRedDebugMsg( "Cycle thread exiting");<br />
th_start_receiving->m_run.EnableWindow(TRUE);<br />
<br />
return 0;<br />
}<br />
here's how CycleSequence function looks like
int COpc_serialDlg::CycleSequence(int times, CString startstring, CString repeatstring, CString endstring)<br />
{<br />
<br />
CString temp_string = "";<br />
int i = 0;<br />
int Stroke_Count = GetNumberOfStrokes( startstring);<br />
CString local_repeatstring = "";<br />
CString local_repeatstring2 = "";<br />
<br />
<br />
<br />
for( i = 0 ; i < Stroke_Count ; i++)<br />
{<br />
<br />
local_repeatstring = startstring;<br />
<br />
<br />
m_serial.Write(Read_Out_Int(local_repeatstring),1,0,0,10);
startstring = Remove_Out_Int(startstring);<br />
<br />
SetTimer( 999 , 15000 , NULL);<br />
WaitForSingleObject(m_idle_event , INFINITE);
<br />
}<br />
<br />
Stroke_Count = GetNumberOfStrokes( repeatstring);<br />
for( i = 0 ; i < times ; i++)<br />
{<br />
local_repeatstring = repeatstring;<br />
for( int j = 0 ; j < Stroke_Count ; j++)<br />
{<br />
local_repeatstring2 = local_repeatstring;<br />
ResetEvent(m_idle_event);
<br />
<br />
PrintRedDebugMsg( "Waiting done");<br />
m_serial.Write(Read_Out_Int(local_repeatstring2),1,0,0,10);
local_repeatstring = Remove_Out_Int(local_repeatstring);<br />
<br />
SetTimer( 999 , 15000 , NULL);<br />
WaitForSingleObject(m_idle_event , INFINITE);
<br />
}<br />
}<br />
<br />
Stroke_Count = GetNumberOfStrokes( endstring);<br />
<br />
<br />
<br />
for( i = 0 ; i < Stroke_Count ; i++)<br />
{<br />
<br />
local_repeatstring = endstring;<br />
<br />
<br />
m_serial.Write(Read_Out_Int(local_repeatstring),1,0,0,10);
startstring = Remove_Out_Int(startstring);<br />
<br />
SetTimer( 999 , 15000 , NULL);<br />
WaitForSingleObject(m_idle_event , INFINITE);
<br />
}<br />
PrintRedDebugMsg( "End of cycle reached");<br />
return 0;<br />
}
there are also other functions in CycleSequence like m_serial.Write , Remove_Out_Int and Read_Out_Int and GetNumberOfStrokes
i did not include them here because i dont think they are causing the problem.
i believe the problem is the way i initalize stuff in cyclesequence and the way i do my loops
using:
- winxp
- VC++ 6.0
- MFC

Function UINT COpc_serialDlg::th_start_sequence(LPVOID lpvParam) must be static

Not necessary. Its very difficult from seeing this code, to find out the problem.
You can put down message boxes in code and narrow down the rpblem code.
Additionally , refer this article by Joseph M. NewComer Joseph M. NewComer[^].

Well, this is a definite no-no from worker threads.
Never touch the GUI from a worker thread, it may cause a deadlock.
Read Joe Newcomer's article on the subject to get a better understanding of how to do worker threads here[^].

Just opened the readme to VseDebug it says it works with
Visual studio.net 2002 2003 Anyone know if you can build it With Visual Express 2005

The following code on a linux gcc compiler gave me an error message:
error - SO C++ forbids declaration of "vector" with no type
apparently,
vector <double> dd; is okay because double is a known type
How can I make g++ recognize t_vertice as a valid type?
Or how can I switch off the ISO compatibilty on the g++ compiler?

Can modify your code with ignore html tags option ? So that it can be readable, understandable.

I've never worked on linux.
But, just a suggestion. Can you try, moving this typedef outside the class ?

no go, still same error message
|
|

I've never used gcc but searching on the error message it seems the likely culprit is
"vector" is not defined, usually because of a missing header or a namespace problem.
If you have the right header(s) included, maybe "std::vector" will work.
std::vector <t_vertice> puntos;
or
using std::vector;
...
vector <t_vertice> puntos;

AttachThreadInput() and set window by SetFocus().
sample:
<br />
BOOL SetWindowActive(HWND hActivedApp)<br />
{<br />
HWND hWnd = NULL;<br />
hWnd = GetForegroundWindow();<br />
DWORD FormThreadID = GetCurrentThreadId();<br />
DWORD CWndThreadID = GetWindowThreadProcessId(hWnd, NULL);<br />
if(FormThreadID != CWndThreadID )<br />
{<br />
AttachThreadInput(CWndThreadID, FormThreadID, true);<br />
}<br />
<br />
if( ::IsWindow(hActivedApp) )<br />
{<br />
SetFocus(hActivedApp);<br />
return TRUE;<br />
}<br />
<br />
if(FormThreadID != CWndThreadID )<br />
{<br />
AttachThreadInput(CWndThreadID, FormThreadID, false); <br />
}<br />
return FALSE;<br />
}<br />

Do I call this function on the oninitdialog function or other events?
thanks for the code....

any time except in hook proc.
