for (unsigned int i=0; i < m_nThreads-1; i++ )
thd_handle[i] = CreateThread(NULL, GenerateThread, &i, 0, NULL);
The problem is that you are taking the address of i and passing it to the thread function. However, by the time the thread function is able to start, i has likely changed and is probably invalid.
Since all you need is the actual value, just pass i (by casting it to LPVOID), and then in the thread function just pass param to CreateResult by casting it to a DWORD.
(I also don't understand why you keep subtracting one from your thread count. Why not just use the correct number to begin with?)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hi All,
I wonder how can I make a combobox without using MFC. Can someone give me a clue about that.
Thanks a lot
|
|
|
|
|
HWND hCombo = ::CreateWindow( _T("ComboBox"), _T("Some Name") , WS_VISIBLE|WS_CHILD|CBS_DROPDOWNLIST, 0,0, 300, 300, hParent, 0, hInstance,0 );
Where hParent is the parent window handle and hInstance is the instance handle of the application/module.

Hi,
I have a CTreeCtrl in an application. When I click on an item, I want to do a particuliar action. To do that, I have to know the number of the item in the tree: first, second, third an so on.
How can I retreive that information ?
Thanks,
Claude

Are tree controls supposed to be viewed that way. What happens to items 2..N when item 1 is expanded? Does item 2 become item 3, etc?
I would opt for using SetItemData() for each item/node in the tree.

Number in the tree....how are you counting? Breadth first? Depth first?
And why do you need that - are you sure there's no other way of achieveing your objective?

Yes, maybe not with those exact methods, but you can edit/format it.

[assumptions]You're using EM_STREAMIN to get text into a rich-edit control[/assumptions]
I don't see how that's going to work - the text isn't in the rich-edit control yet, so won't be accessible through the control.
I suspect the only way to do it is to tell the control that you're giving it RTF and annotate the text with RTF markup - here's the RTF spec[^]

Exactly what I was thinking
I am trying to display a Storage Dump From the Rich Edit
So...... On the left hand side I would have 0000010 the 16 bytes newline
000020
I would like to high light the storage location So...
In the call back function I would probably mark it up with XXXXXX
Once the text is in the Rich Edit Object. I would do A FindText to give me the index of
the current XXXXXX Setsel give it the attributes I want
Then ReplaceSel with the right Storage location number
thankx
Again

hi,
i am creating some CStatic based controls on a dialog with a regular MFC DLL. (MFC statically linked)
so ,main application calls some functitons in DLL, Like: Create ,Resize ,Move
and DLL creates control on main app's dialog and manages control as main app needs
my problem is:
with this method , tooltips , TAB , CTRL + combinations do not work
could you help me to solve this problem, Please
thanks in anvance

Do let me know the exact purpose for using static control.
Because the functionality that you require can be done using CStatic, however it is easier to use some other control like CButton and then customize it to use in whatever way you want.
CButton already has Tab and tooltip enabled.
Also to enable tab you need to first set the property tabstop to TRUE(this is FALSE by default for static controls) Then you need to write code to show the focus on the static control.
See the following URL to show tool tip on static control:

thank you for your reply
but the problem is not that ,i knew that and tried but it does not work because,i am creating the control from a dll , i think this is related with the message loop, but i could not find a solution to this
this is a relevant link and this was not work also

Hi there.
I want to create jpg file programmatically.
Lets say I have some text "Hello", Now I want to create a jpg file that contains this text.
Thanks

So have you bothered to study the JPG file format?

Not yet. I was mainly looking for some sample code that can do the trick.
Can you please provide some pointers to do the same?

Have you searched the internet and CP? Usually, nobody feels like offering any help to people who are not willing to help themselves. Not to mention you're asking for "the code" to do something that's extremely trivial. Like I said, in my other reply to you, there are two steps to it. Go ahead, give it a try and come back with a specific question if at all.

Two steps:
1. Draw your text to a bitmap.
2. Compress it to JPEG.

I want to do this programatically.
I think you have suggested using some tool may be mspaint.
If you are talking about through the cose itself, then please provide more details in raegrd to the sugegsted steps. Thanks.

I knew you wanted to do it programmatically. Have a look at Drawing lines, shapes, or text on bitmaps[^] and then you'll be left with compressing a bitmap to JPEG. A search must bring up an example, if you ask me.

Have a look at the jpeglib[^] stuff.
IMO, it's not an easy task if you want to do it completely manual.
Like other said, create an in-memory bitmap and save-as jpg with a known API like CImage or something similar.
