go via the tree item not the text itself:

use TVIS_BOLD and set the tree item to this attribute
(I can't remember how though but you can look it up.)

good luck.

First of all use GetSelectedItem() which will return u the selected item and then create the TVITEM struct specifying the mask value as TVIF_TEXT, and hItem as the selected item and state as TVIS_BOLD.

This will bold selected item's text even at the runtime. Wink | ;)

Use a timer (see the "OnTimer" event) and use CTime::GetCurrentTime.

It sounds like you are wanting to create a scheduled task. If so, check out the ITaskScheduler and related interfaces.

Hi,

I have created a compiled help file outside our app. Now I would like to call this chm file by the press of a button (test project) or via a menu.

How can you do this?
Do you need to include this in your project or can you specify the path? (I prefer option 2).

tnx 4 your help!

Sorry. I meant \n. I tried \n and \r and they did not work.

I am trying to display some text on the screen and need to show it in a window that sizes itself to the text but I will need to limit the width to the screen width so I may need newlines in the text.

how to determine if class created before

I have a generic class named CMainHandler. I want to be sure if it was created before. From debugger window i see its value is 0xcccccccc but i can do something like this:

if(m_mh != 0xcccccccc)
delete m_mh;
else
m_mh = new CMainHandler(MODEUDP);

m_mh is CMainHandler instance

Thanks in advance

I dont think it's good idea...Y dont u initiaze it to NULL very first?

In the constructor of the class that uses this class, set it to NULL. So you can check if the value exist or not...

No. In many cases when you compile with debugging and run in a debugger, something will change uninitialized variables to be a obvious bogus constand. In your case it is 0xcccccccc. My debuger uses 0xaaaaaaaa! So already your program is not portable to my debugger.

When you are running optimized code outside of the debugger, those variables are not initialized at all, instead they take on whatever value was in that memory location before! C++ trusts you to know what you are doing. If you don't initialize a variable in optimized code, the optimizer assumes you know by some other means when that variable is initialized, so it doesn't waste a cycle setting that variable.

A pointer is allowed to be 0 (NULL), a hardware location defined by the designers of the hardware, or something the compiler provides out of your control. You can compare against the first two because they never change. The last one should always be treated as if it will change all the time.

Note that what's said earlier.

Its good practice when you delete an object you set it to NULL also.

eg.

SomeObject obj = new SomeObject();<br />
<br />
//...<br />
<br />
delete obj;<br />
obj = NULL;

if you check on NULL before using it, it will at least be NULL and not 0Xcccccccc.

Go to the class wizard and say Add Class. At that particular time, instead of accepting the system generated class, click on the Change button and specify the class header file and the implementation file.
