I called FindFirstFile with the search mask "*.m3u" and it finds a file with extension ".mp3~" (i.e. with a tilda at the end)
Is this a bug in FindFirstFile, or am I doing something wrong?

No I don't think so,Could you show me your coding for that here !!!

WIN32_FIND_DATA findFileData;
HANDLE hSearch;
wxString strMask, strHit, strDiff;
strMask = "F:\\mp3\\Downloaded\\AC DC\\*.mp3";
hSearch = ::FindFirstFile(strMask, &findFileData);
while (hSearch != INVALID_HANDLE_VALUE)
{
strHit = findFileData.cFileName;
}
::FindClose(hSearch);
this will return a hit for any file with extension .mp3~ in said directory

|

It's the string class from the wxWidgets library
|
|
|
|
|
try to debug the it what exactly extension it has taken
i run this on my pc with CString its working fine
|

It doesn't make any difference what string class you use. The bug is in FindFirstFile.

Please I'd like to know the syntax in using WM_GETTEXT(), for use in retreiving text from an edit box. Where should this syntax be used?
|
|
|
|
|
it you know the ID of the Edit Box use
GetDlgItemText api

Many (actually most) Windows API calls that operate on windows work by sending the target window a message. WM_GETTEXT is the message sent to retrieve a window's text. Both these code fragments will get the edit control's text:
char szText [TEXTLEN];
HWND hWndEdit = window handle of edit control;
::GetWindowText (hWndEdit, szText, TEXTLEN - 1);
char szText [TEXTLEN];
HWND hWndEdit = window handle of edit control;
::SendMessage (hWndEdit, WM_GETTEXT,
(WPARAM) TEXTLEN - 1,
(LPARAM) szText);

Hi guys,
i am new to multithreading in MFC. I have gone through many of the examples posted on CodeProject, but i am still not satisfied.
What i want to know is that, suppose i have my window, and i want to create a thread which, say, takes care of all the keyboard inputs, another thread which takes care of all the mouse inputs.
So far whatever examples and tutorials i have gone through first create a new window using a thread and then control all the operations. I want my parent window to have a thread to do all those stuff.
Can anyone help me out.
 Thanx in advance!

With MFC, all GUI interactions must take place on the UI thread; this is inherent to the MFC architecture. You can, however, have separate worker threads that do the actual work associated with keyboard and mouse actions. The UI thread detects a keyboard and/or mouse action and starts a worker thread. The worker thread does its thing, and the posts messages back to the UI thread as necessary.

This statement sounds like you want to make a general change in how Windows applications work. I think you would be better off learning how to use the Windows input model, rather than trying to subvert it.

Hi thanx for replying,;)
Is it necessary to do my stuff in a worker thread?
Actually i am a little nervous in creating a worker thread. i always have one confusion, how will i assign any job to a function which is not a member of my class. I mean, how will this function
UINT threadproc(void* para)
be able to access the members of my class when it is not a member of my class.
Can you please elaborate on this point.
Thanx in advance.

That depends on what you need to do. If the process takes a lot of time, you don't want to block the user interface while the process runs. That sort of thing is something you can put in a worker thread.

I always use something like the following:
class Stuff {
static UINT ThreadStart(LPVOID parameter);
UINT Thread();
};
UINT Stuff::ThreadStart(LPVOID parameter)
{
Stuff *_this = (Stuff *)parameter;
return _this->Thread();
}
UINT Stuff::Thread()
{
}
AfxBeginThread(ThreadStart,(LPVOID)this);The static member function matches the prototype required by AfxBeginThread(). You use the parameter to pass a pointer to an instance of your class. In my example, I passed the this pointer, which means I'm starting the thread from another member function of the class. The function that does the actual work of the thread is called Thread(), and since it is a member function, it can access other members of the Stuff class.

Hi.
The easist way is use
AfxBeginThread (threadproc,hwnd,threadpriority)
threadproc : threadfunction with form
UINT threadproc(void* para)
{
//here do any thing
return true
}
hwnd:this is the para parameter on threadproc function
threadpriority:may be
1-THREAD_PRIORITY_NORMAL
2-THREAD_PRIORITY_LOWEST
.
AfxBeginThread return CWinThread object this object can be use to suspend and kill the thread
u can use many thread with the above story
If this not help u contact me on faroq_tam2004@yahoo.com
to get sample MFC program describe MFC MThreading
bye.
On Earth nothing impossible,
while your mind running.

How would one retreive data input from the keyboard into a dialog box, which the compiler would process at run-time? I thought that making an instance of the class object which contains the data would be enough; but this doesn't cut it. See the following code:
<br />
void unbound(double *unbd, int nSize)<br />
{<br />
enum{nSize = 100};<br />
double A[nSize],B[nSize],k0[nSize],k1[nSize],s[nSize],expi[nSize],a[nSize],b[nSize];<br />
<br />
void bessk0(double *x,double *k0,int nSize);<br />
void bessk1(double *x,double *k1, int nSize);<br />
void ei(double *x, double *expi, int nSize);<br />
<br />
double x=0;<br />
<br />
s[0] = 1;<br />
a[0] = x*sqrt(s[0]);<br />
b[0] = 2*sqrt(s[0]);<br />
<br />
bessk0(a,k0,nSize);<br />
bessk1(a,k1,nSize);<br />
ei(b,expi,nSize);<br />
<br />
A[0] = k0[0]/(x*sqrt(s[0])*k1[0]);<br />
B[0] = (1-exp(-2*sqrt(s[0])))/(2*sqrt(s[0]));<br />
<br />
unbd[0]=0.5*(A[0]-B[0]-expi[0]);<br />
<br />
for (int t=1;t<nSize;t++)<br />
{<br />
CKuchukDlg MyClass; <br />
x = 2;
<br />
s[t] = 2*t*PI;<br />
a[t] = x*sqrt(s[t]);<br />
b[t] = 2*sqrt(s[t]);<br />
<br />
bessk0(a,k0,nSize);<br />
bessk1(a,k1,nSize);<br />
ei(b,expi,nSize);<br />
<br />
A[t] = k0[t]/(x*sqrt(s[t])*k1[t]);<br />
B[t] = (1-exp(-2*sqrt(s[t])))/(2*sqrt(s[t]));<br />
<br />
unbd[t]=0.5*(A[t]-B[t]-expi[t]);<br />
}<br />
}
When line **** read x=MyClass.m_dWellRad;the compiler didn't process the variable m_dWellRad at run-time, but simply used x = 0(initialization). When I used x=2, it used the latter variable.
How then can I make the compiler use the value input from keyboard into my dialog box at run-time?

The statement
CKuchukDlg MyClass; isn't sufficient by itself to display the dialog. You need to do something like this:
CKuchukDlg MyClass;
MyClass.DoModal(); That will display the dialog.

return 0;<br />
}
Visual Studio compiler gives an error like;
cannot convert parameter 1 from 'ArrayType [7]' to 'int []'
How can I solve this?
Thanks in advance.

tis abt getting keyboard eventz in a dialog box having many windows in it!!!!!how do i get the keyboard events to come to my dialogbox even when i am in some other window of that dialogbox???any ideas??

You will need to look at application wide hooking. That is, every time someone hit a key it gets preprocessed by your hook. A good place to start looking for this information is articles on custom menues, which offten need to hook the application inorder to change the appearance of all menues in the application. There are also, more than one article in the MSDN library on hooking (most are for subclassing though).
Keywords: hook, hooking, subclass, subclassing, application, system.
