 What do you mean ? You mean command line arguments ? If yes, then simply open the command prompt and add them after the executable name. If that's not what you are looking for, then you should explain more in details.

|
|
Also, from within the Visual Studio IDE, you can go to the project properties in the "Debugging" section
and put your commandline arguments in the "Command Arguments" setting.

Is there a particular reason to do that ? If your program is not running on a multicore, then this will probably slow down the procedure, as you will incur the cost of thread switching and you'll need to protect some part of it for multi-threaded access (which will also slow down).

Some people think multi-threading would make it run faster ...

Yeah, but some people might be wrong 
|
|
|
|
|
make this multithread is leading into headache, because you'll have to synchronize your threads, so that each thread don't count the same file twice...
synchronized them is certainly going to make your multithread solution slower than a single threaded one...
|
|
|
|
|
yes that is the question that how can i assign the equal task to each thread.
|
|
|
|
|
IMO, using multiple threads to access a physical drive will make things worse.
Imagine the battle between the threads to get the control of the drive, there is only one moveable head on a disk.
|
|

|
|
After enumerating the files i want to process on files, in windows there is thread based switching, so if i have multiple thread my work will be fast. what do you think about this.

Of course DlgDirList returns number of folder or files when you use of it on the listbox.

Did you try to use your debugger to locate the problem more precisely ? Did you check the callstack and inspect the different variables around the crash occurence ?
With so little information, there's not much we can do...

Hi Cedric Moonen,
InitThunk((TMFP) &CExtBox::HookProc, this);
m_hHook = SetWindowsHookEx(WH_CBT, (HOOKPROC) GetThunk(), NULL,GetCurrentThreadId());
ASSERT(m_hHook);
nRes = MessageBoxIndirect(&mp);
if(m_hHook)
UnhookWindowsHookEx(m_hHook);
This is the code part i am using and it was crashing when it calls MessageBoxIndirect().
This code was running from a long time now in fresh version of release this is giving problem. If i use MessageBox( ) then it is working but the function that i am calling is used in somany places so i cannot avoid it.
It is giving the following Application error

Check Listing the Files in a Directory[^] and add the string to list box.

Set the LBS_MULTIPLESEL Style for List Box

ok.. thanks.. i got that..
now another thing that i need to do is to merge the files. say in the listbox there are 5 files. no i need to merge this file and save the merged file in another file name. what needs to be done for this?
how can i save the file names in different variable?
|

These are very basics, you refer msdn if you are using MFC, CListBox, CFile, CString member functions can be made use.
Chandrasekharanp wrote: say in the listbox there are 5 files
refer CListBox:: ( GetSelCount, GetSelItems, GetText)
Chandrasekharanp wrote: no i need to merge this file and save the merged file in another file name. what needs to be done for this?
Refer reading and writing to file using CFile.
Chandrasekharanp wrote: how can i save the file names in different variable?
from my previous reply the FindFirstFile API fills the WIN32_FIND_DATA it has cFileName member and use CString.
I expect you are not askig for Code for copy paste.

|

no. i don't expect that from u.. at times it happens that u go bonkers...at such situations u send these queries...
anyways thanks yaar.

will certainly ask u if there is something needed..

if i have to send the selected items to another listbox what functionality should be used?
|
|
|
|
|
If you got how to get the selected items from List box and how to add list box items then mix these functionality.
|
|
|
|
|
Guess i got a problem here...
i am sending u the code.. please help me in this.
say i have 10 items in the listbox. not if i i click the 4 to the 8th item in the listbox, the first 5 items are displaying the listbox.
<br />
CArray<int,int> aryListBoxSel;<br />
int nCount = m_listbox.GetSelCount();<br />
aryListBoxSel.SetSize(nCount);<br />
m_listbox.GetSelItems(nCount, aryListBoxSel.GetData());<br />
<br />
for(int i=0;i<m_listbox.getselitems(ncount,arylistboxsel.getdata());i++)><br />
{<br />
CString str,str2;<br />
int n;<br />
n=m_listbox.GetTextLen(i);<br />
m_listbox.GetText(i,str.GetBuffer(n));<br />
m_list.AddString(str);<br />
}<br />
<br />
what is the reason for that?<br />
<br />
<br />
</m_listbox.getselitems(ncount,arylistboxsel.getdata());i++)></int,int>
