You can also try making sure not to remove items and then add them back, or to add and then remove items.

Could you explain a little bit more. In my case i don't remove anything i just and or update items every 100ms...
Here is my code (may be it can help)
OnTimer()
{
GetTreeCtrl().SetRedraw(FALSE);
while (something to add or update)
{
//Add Trace item in the ListCtrl/Treeview
AddOrUpdate (SetItem or InsertItem)
}
//Allow to draw all modified lines in the ListCtrl
GetTreeCtrl().SetRedraw(TRUE);
}
|

Maybe you should call SetRedraw(TRUE) only when there is a change in the tree.
Something like this:
OnTimer()
{
BOOL bChanged = FALSE;
GetTreeCtrl().SetRedraw(FALSE);
while (something to add or update)
{
bChanged = TRUE;
//Add Trace item in the ListCtrl/Treeview
AddOrUpdate (SetItem or InsertItem)
}
//Allow to draw all modified lines in the ListCtrl
GetTreeCtrl().SetRedraw(bChanged);
}

Unfortunatelly... I really think it comes from InsertItem/SetItem itself... it seems it erase the item and redraw item... and that for every items it's a christmas tree. 
|
|
|
|
|
At one time I was creating and deleting tree items in a tree and it flickered. Are you doing anything similar? Maybe you are changing node names or similarly visible attributes.
|
|
|
|
|
Yes I change visible attribute but i do not erase anything. The blinking is quite special because even if my timer is 100ms the blinking period is not 100ms... it is almost 500ms... very strange, most of time treeview items remains and are not blinking even if item name changed! and others time it seems to erase item and redraw it => so blinking effect...

myTreeView.BeginUpdate();
// do my refresh stuff
myTreeView.EndUpdate();

Hi,
I have several applications that have to use a set of same constant values.
Those constant values are defined in several CPP files in the
following way:
const char* name = "text";
I want to compile those CPP files to some software component
(maybe lib or dll) in order to use it in runtime in my application.
I considered to build those CPP files to DLL and then to load it explicitly
(by LoadLibrary() and GetProcAddress()).
The problem is that this way requires redefinition of all the constants defined in
CPP files in my executable and I would like to avoid the redefinition.
Is there any other way to compile those CPP files to software component in a way that my
applications will load it in the run time and there will be no need to redefine the constants
and no need to compile or link my applications each time the CPP files are changed?
Thanks in advance,
Avi

A solution with configuration files is not good ? It is just a suggestion, maybe it's not adapted to your problem.

If you use GetProcAddress you don't need to include files. You just need to typedef the prototypes of the functions that you need to load.

Suppose in WSAAsyncSelect model.
Peer A send "1234" to peer B. Just when "12" is arrived at Peer B, the network is disconnected. Will peer B be notified with FD_READ and receive "12"? What is the case if the receiving buffer is just full after receiving "12"?

I think yes peer B be notified with FD_READ and receive "12"

Damn!! It has been unable to delete for 10 minutes!
Yes I deleted my posts. I close my IE, and re-start an IE instance, ... my posts get back!  Is this because of the redundancy server of CP ?

but then whole application gets closed.
How to do it efficiently?
Instead of that call AfxGetApp()->CloseAllDocuments();

Hi All,
I have succeeded in compiling a massive project, originally from vc6 to VS .Net 2005.
Now, while linking I am having loads of linker errors with the above code.
LNK20019 and LNK2001. Giving error msg that some symbol is not found. Actually, the library with the symbol has been already compiled as dll.
I looked into the documentation. The errors may be caused by
1. use of Inline functions (2019, also sometimes 2001)
2. use of C Runtime LIbraries (2001)
I dont know how to solve this problem. Can anybody tell me what should I do to remove these errors ?
I know all the missing symbols are there and the libraries are my own, so I can also change the code of the libraries.
this is the buildlog of one of the projects in the solution.
I also attach the implementation of a small class which is referenced and the symbol (destructor of that class) is not found and results in the error.
I hope this helps you guys to guide me.

Hi,
I have to work on a lightweight dial up application for connecting to our company servers. Is there any link which talks about this kind of applications? What does it mean by RAS dialing capability?

Thank you.. I will go through it. How to start working with dial up connection projects? Is dialup networking and dial up connection projects are one and the same? Can anybody shows me a link to study on the topic?
