I am curious as to why you would go to the trouble of starting threads when all it needs is to call SetTimer in OnInitDialog and have a WM_TIMER handler that calls KillTimer and EndDialog when the timer event fires.

hai broom, may be you are right.
but i want to know weather timer is different in performance to the thread.
AFAIK timer is also a sort of a thread.
in the example which i have given, he can even customise his second thread, such that, it kills the dialog, after uploading is completed.
iam not sure weather it can be achieved through timer.
thanks.
Suggestion to the members:
prefix your main thread subject with [SOLVED] if it is solved.

Timer performance is the same regardless of whether it is called from the primary thread or a secondary thread. A timer is NOT a thread-type object - it has no executable context. It is an object that is queued by the OS and released / signalled by the OS when the period has expired.

If a simple modeless dialog is used by the main thread to indicate download in progress, the main program can then destroy the box when download is complete. This is how most progress dialogs are implemented.

Which is complete overkill, given that two additional threads were suggested.  Using SetTimer() is the simplest and most practical solution.

like this:
1.When No.1 process reading a.txt, No.2 process read a.txt simultaneity, both read as usual.
2.When No.1 process reading a.txt, No.2 process write a.txt, No.2 process wait No.1 process read complete then write.
3.When No.1 process writting a.txt, No.2 process read a.txt, No.2 process wait No.1 process write complete then read.
4.When No.1 process writting a.txt, No.2 process write a.txt, No.2 process wait No.1 process write complete then write.
How use _locking(CRT functions) or LockFile, UnlockFile(Window API) finish above. it puzzled me someday. If somebody know, please tell me.Thanks very much.

use some global flags(may be two or three),
which indicate the state of the other thread.
say for example,
int process1flag=0,process2flag=0;
and make the flag 1 if it is writing and make it 2 if it is reading.
after write or read operations, reset them to 0.
observe the same in the other process and take the decission depending on the flags.

He is talking about different process not different thread.

You should use some synchronization with the help of Mutex.
Check CreateMutex(), WaitForSingleObject() and ReleaseMutex(). You can find many samples in CP that uses mutex.

Hi all,
i am Encoding media files using WMSDK.As given in SDK Help i am using IWMEncoder interface for encoding. as part of that example
<br />
hr = pEncoder->Start();<br />
<br />
printf("When encoding stops, press a key to close the console window.");<br />
<br />
if ( SUCCEEDED( hr ) )<br />
{<br />
while(!kbhit())<br />
_asm nop;<br />
<br />
hr = pEncoder->Stop();<br />
}<br />
i don't wants to use kbhit() and wants to complete hole file encoing process automatically.
For that we have functions put_Autostop() and get_Autostop() but there are not working properly.
So if anybody has an idea about that give plz.

when i do write the following:
m_pRecordset->Open("CREATE TABLE MY10151109(ID INT,Hex_Fangwei TEXT,Hex_FuYang TEXT,Hex_QingXie TEXT)",
theApp.m_pConnection.GetInterfacePtr(),
adOpenDynamic,
adLockOptimistic,
adCmdText);
it runs OK;
but when i do it like this:
CString mstr;
mstr.Format("CREATE TABLE '%s'(ID INT,Hex_Fangwei TEXT,Hex_FuYang TEXT,Hex_QingXie TEXT)",TB_Name);
m_pRecordset->Open(mstr.AllocSysString（），
theApp.m_pConnection.GetInterfacePtr(),
adOpenDynamic,
adLockOptimistic,
adCmdText);
appear runtime error
who could tell me why , and what should i do?

try putting mstr there and see
i.e. remove .AllocSysString().
AFAIK it should work.

but,when WorkThread() is running,I'm worried about func() have been finished result in "struct SInfo SOCKINFO" be released.That's WorkThread() must be obtain a correct "struct SInfo SOCKINFO"?

You can: 1) create a different context menu at design time and bring up the one you need, or 2) create one context menu at design time and modify it at runtime, or 3) create the whole menu at runtime.

你可以为每一种邮件添加一个资源菜单，根据不同的item，load相应的resource ID
POINT point;<br />
UINT uFlags;<br />
<br />
GetCursorPos(&point);<br />
<br />
m_ctrlTree.ScreenToClient(&point);<br />
<br />
HTREEITEM hItem = m_ctrlTree.HitTest(point,&uFlags);<br />
<br />
if(hItem)<br />
{<br />
hTreeCurrent = hItem;<br />
ClientToScreen(&point);<br />
<br />
VERIFY(menu.LoadMenu(IDR_TREERCLK));<br />
pPopUp = menu.GetSubMenu(0);<br />
}

I have a dialog template with some control on it.
When I will press a button on this dialog, I want to clone this parent dialog and modied some of its control and display this clone dialog as a modal or modeless. At that point I have two dialog one is the original and another is the clone version with some modification.
I will appreciate your help.
Thank you.

Can't you just create another dialog template with the modified controls on it?

My first dialog is resource based. I want to clone it after it is instantiated.
Are you suggested, to get the dialog template of the existing dialog and create indirectly anothe dialog. How I can get the controls and their current status of the first dialog.
Do you have any more idea? Is it possible to implement a copy constructor?
Thank you for your suggestion.
