Thanks for sharing with me all of these. 
However since I am new to PIC programming, it is better to move with some emulators. Honestly I cannot spend a lot at this moment for these stuff. 
I appreciate your help all the time...

Hi,
I have a Dialog based application, to transfer a file I am using a thread (say T1).
If I need to abort the T1 I need to press cancel button, for abort process I am using a memeber variable (bStopPushThread ) as a flag. If I set it ture it comes out of T1.
But my application getting hang. Code on Abort button click is below:
if(g_hThreadHandlePush)
{
m_bStopPushThread = true;
WaitForSingleObject(g_hThreadHandlePush,INFINITE);
CloseHandle(g_hThreadHandlePush);
}
But It I dont use WaitForSingleObject(), it wirk fine, T1 treminates.
I can check using debug..
If I use WaitForSingleObject as pointer come on this statement application hangs and I even cant check the T1.
Please suggest me solition.

Could you also post the code of the thread in which the m_bStopPushThread variable is accessed ?
|

|

Are you completely sure g_hThreadHandlePush is the handle of the thread that checks the flag?

You probably have code looking like this in your thread:
while( !m_bStopPushThread )
{
}
Chances are that the m_bStopPushThread has been optimized into a register in your thread controlling loop which means that the thread won't see the value change.
This happens if the variable is not written to inside the loop.
Building a debug version disguises this behaviour since optimizations usually are turned off.
The remedy is to declare the variable m_bStopPushThread as volatile, which will tell the compiler to read its value from the variables memory address every time and not to hold its value in a register.

If I had to guess, as someone already stated, g_hThreadHandlePush may not be the actual thread handle that you're expecting. To follow up on that, I hate to see people wait on something for an INFINITE time span. I know some disagree, but imagine if someone works on your code years later when you're not around and removes (for example) the m_bStopPushThread variable... they would end up with a freeze and it would be very hard to pinpoint where the freeze is occurring (debugging in multithreaded applications gets complex). I think you're better off setting a reasonable timeout, then alerting as to what occurred (using trace statements, message box, whatever).

Hi,
I am using CRichEditCtrl. I need to add percentage in a loop at end of text.
Every time I need to call GetWindowText() and append text and again SetWindowText(), but due to this I am getting flickring.
How can I add only a single line og text in CRichEditCtrl so that I can avoid flickring.
|
|
|
|
|
|
|
Don't know how much it would flicker, but try using CRichEditCtrl::SetSel[^] and CRichEditCtrl::ReplaceSel[^] to change only the part of the text you want. You might try combining it with CWnd::SetRedraw[^] and CWnd::RedrawWindow[^] to have it redraw itself only once after the text has been changed.

I am new to the MS TR1 2008 implementation of regex.
My application used to use a regex provided by a third party sofware house (Tropic Sofware East) - but I decided to move to MS TR1 version (from all the reports I read - I am beginning to regret that decision).
Has any one else experienced problems with matching reg-expressions that are case sensitive? Here is an example:
...
fOption |= std::tr1::regex::icase; // Ensure case-insensitive.
...
try
{
a_pRegex->assign( a_pszString, fOption );
}
...
// later
std::string str = ( LPCTSTR )szString;
if( regex_match( str.begin(), str.end(), *m_pRegex ) )
{
// Yippie .. a match
...
}
It's not important about the variable names that get passed around in the code (as the snippet is obviously heavily edited. It nevertheless does not perform a match - even on a simple 'HELLO' and 'H[a-z]+O') - if anyone has any pointers as to where I am going wrong - I'd appreciate the help.
Regards.
James

I've not ever used that library, but what about:
H[A-Z]+O

As I read the question, the OP isn't looking for an uppercase regex; he wants case-insensitive matching.

Hi.
Yes, that works, the problem seems to lie in that the chars between the brackets [] do not get processed in a case-insensitive way.
I believe the following describes the problem:
www.comeaucomputing.com/iso/lwg-active.html#523
It is still flagged as an open issue - if this is actually the case then this is madness. The least I expect from a regex, is to be able to perform a case-insensitive comparison on a given range of characters.

So then how about:

Hi.
Thanks very much - thats what I did in the end. I know the example I gave was trival and the real expression is significally more complicated; so I wanted the fastest regex I could get. The process operates on potentially many miliions of lines of data and I wanted to keep the process as 'inexpensive' as possible.
Neverthless - thanks a lot for your time and effort pondering this.
Many thanks.
James.

Obvious dumb debug thing I'd do - dump the arguments you're actually using immediately before the regex_match() call. You use a_pRegex in one place and m_pRegex in another, so I, for one, don't know what is actually going to be used...

I want to build a parameters string, but keep each parameter on it's own line for easy editing and reading.
The variable is a CString, and I want to make 1 giant string out of it. Just looking for the proper way to do this.
lp_Parameters = "/iu " +
"IIS-WebServerRole;" +
"IIS-WebServer;" +
"IIS-CommonHttpFeatures;" +
"IIS-StaticContent;" +
"IIS-DefaultDocument;" +
"IIS-DirectoryBrowsing;" +
"IIS-HttpErrors";
|

get rid of the + operator.
so
CString string("/iu "
"IIS-WebServerRole;"
"IIS-WebServer;"
"IIS-CommonHttpFeatures;"
"IIS-StaticContent;"
"IIS-DefaultDocument;"
"IIS-DirectoryBrowsing;"
"IIS-HttpErrors");

Adding strings together and CString.Format() do give the same results. However, for some uses, like if the string is periodically edited, adding strings is easier to change / expand / delete things without having to go back and fix the formatting control string too. Especially when mixing constant strings and variables to create a MessageBox string.
