problem is that. you are sending the Ctrl ID in the message Field and trying to get in WM_COMMAND message!
better way of sending it is
PostMessage(hwndTagEditorDlg,WM_COMMAND,IDC_HIDDEN_BTN,0); and capturing that in WM_COMMAND wParam Parameter

A small clarification Alok:
you've omitted the notification code for the button which probably should be BN_CLICKED. The WPARAM parameter for the WM_COMMAND message contains both the control ID and the notification code. The code for simulating a user click on the IDC_HIDDEN_BTN should look like this:
::PostMessage( hwndTagEditorDlg, WM_COMMAND, MAKELONG( IDC_HIDDEN_BTN, BN_CLICKED ), NULL );

offcourse.. you can also use SendDlgItemMessage!

Very true, but that call chain will eventually call ::SendMessage() which is synchronous. Perhaps the idea was to have an asynchronous implementation.

you can make SendMessage Sync call Async by using ReplyMessage Api!

Umm, not exactly...
It may be that we're talking about different levels of abstraction, but the call to ::SendMessage() always block until the message is "handled".
In a single threaded situation a call to ::SendMessage() would be similar to a function call, the message will never appear in the message queue. In this situation ::ReplyMessage() has no effect since it wouldnät make any sense.
When a thread sends a message to another thread with a call to ::SendMessage(), the sending thread will block until the receiving thread has handled the message. In this situation you may call ::ReplyMessage() to release the blocked thread before returning from the message handler in the receiving thread.
MSDN says: If the message was not sent through SendMessage or if the message was sent by the same thread, ReplyMessage has no effect.

what should i write suppose i want to pass the extra parameter in sendmessage, like passing the selected index of the listview control.

pass it in lParam parameter

Hi all,
I have created a thread and would like to know when the thread is called, is that the only time that the code within the thread would be executed? Or could one call the thread again to execute the code within the thread again. Hope this makes sense ...
void TestProc(void *par)
{
printf("Just testing some stuff\n");
}
...
int valTest = 1;
HANDLE handleTest;
handleTest = (HANDLE) _beginthread( TestProc,0,&valTest);
WaitForSingleObject(handleTest,INFINITE);
...
Many thanx in advance

Hi
i am not understanding exactly how the bit fields implemented
if i create the following structure
struct word
{
unsigned int bit1 : 1;
unsigned int bit2 : 1;
unsigned int word3 : 16;
}
internaly how many bytes will be saved and is the 1 means 1 bit ?

Ayman Mashal wrote: is the 1 means 1 bit ?
yes.
so totally, your struct uses 1+1+16=18 bits, but as the lower piece of memory you can address is the byte, you will use 3 bytes (as 2 bytes - 16 bits - are too few).
so, from usins 3 unsigned ints (which are commonly, on 32 bits machines, 32 bits wide), you're saving 12-3 = 9 bytes !
|

Acutally, since the OP has declared his bitfields as int xxx : 1, it will use 4 bytes (only three will contain valid values).
If you save to a file, or even in memory, it will still consume 4 bytes.

 the :1 notation means 1 bit, no byte

Obviously it means one bit. But by declaring it as
int mybitvar : 1
it will still consume 4 bytes when stored.
Maybe I don't understand why you think my reply was in error?

Hi,
I'm trying to create simple MDI program with splitter with two panes, the first should be TreeView (or any other ctrlview for that matter) the second one I'd like to be the FrameWnd client window, where the child windows will be present. How do I do that? (I saw the examples but all of them use all panes for views).
I guess the same result can be achieved using resizeable docked dialogbar,
but it's more complicated to implement.
thanks,
Guy.

hi,
How to select a item in a tree control if i know path of that particular item.

yuvachandra wrote: i know path of that particular item
Whats does this mean ? Is it text displayed ?
You need to traverse tree control items inorder to go to particlular node and select it.
|
|
|
|
|
i have a path D:\New\NewFolder.Now i have to select the item which contains the text NewFolder.How can i do it.

I am assuming D: is root Node and you first have to find New Under it using GetChildItem and GetNextItem and comparing the text with New, after you find Text New, GetChildItem and GetNextItem to Find NewFolder, using TreeHandle you got from search use SelectItem select that item

Hello all,
As per my previous post i m trying to pass two parameters to my thread one is CString n one is integer.
For that i have made a structure
which constitute of two variable CString and int resp..
in a function i m making structure object like this
test *obj;
obj = new test;
n giving its variable values like this
obj->item = 10;
obj->str = "nItem";
n after that starting thread like this
Ping = AfxBeginThread(PingThread,obj);
my thread LPVOID paramter recieves its value
inside my thread i m able to retrieve only first value either its a CString or an integer
cstrHost = *(static_cast<cstring*>(pParam));
int_val = *(static_cast<int*>(pParam));
trying to retrieve 2nd int value is giving a garbage value
can anybody guide me in this....
