A common problem in release (vs. debug) builds is the use of uninitialized variables (which contain garbage in release mode and zero in debug mode). Check your code for these. If the problem persists, you'll need to post a code snippet (not your entire app!) in order to get more help.

What exactly are you updating? UpdateWindow() updates the client area of the specified window (or control) by sending a WM_PAINT message to it. Is that what you are expecting?

Yes.. I think that I am expecting.
I have static control that keep track of num of files in the loop like 1 2 3 4 5 ..
in debug mode, you can see the num of files: increasing as the loop goes on even you open other windows. If it is not running in debug mode, the increasment still as soon as i touch other windows. It looks like the program is freezed but busy working.
Isn't ::UpdateWindow(m_hWnd) solution to this? What am I doing wrong?
Thanks

Not hardly.

You need to create two CStatic variables, one for each control. Make sure the DoDataExchange() method is correct:
void CMyDialog::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_STATIC1, m_static1);
DDX_Control(pDX, IDC_STATIC2, m_static2);
}Now when you need to update them, simply call SetWindowText() like:
int nCounter = 1;
CString strCounter;
strCounter.Format("%d", nCounter);
m_static1.SetWindowText(strCounter);

Yes David.
That's what I have.
It gets updated.. But it is just doesn't show it anymore as soon as after I touch or click or focus on other windows.
The dialog looks like it got frozen. It no longer update any controls on dialog. All the dialog controls become alive or awake again when it gets out from the loop.
I thought inorder to prevent from dialog to get looks frozen, I have to call ::UpdateWindow(m_hWnd) to update or redraw the whole dialog including every controls that I have on dialog.

That indicates that you're doing the work in the main UI thread. The UI is not going to be responsive as a result. You can use SetWindowText() to update the control immediately if that's the only problem you have, otherwise move the loop to a worker thread.

Thanks
I had changed to worker thread.
it is working.
thanks.

thanks for your answers.
What I meant is:If there is a simple way like in Visual Basic where you right click at the properties of the button and you can change the back color the color you want.
Is there some thing like this in visual studio C++?
thanks again

Not in the dialog designer, but you can handle the WM_CTLCOLOR message and set the background colour there.

Hi hektor kashuri,
I suggestion that you derived CButton and use WM_DRAWITEM
|
|
|
|
|
As others have pointed out, there's no VB-like "background color" property you can set. Instead, you'll need to paint the button yourself. See this[^] article.

hi there,
i need to send the decimal number "2" as a parameter to a function, but the method passes this parameter as a (u_char *). how can i stop this number from being converted to its ascii value of 50 when passing it through the parameter.
i can't send the ascii value of "2", as this is defined as STX in ascii table.

"2" is not a number but a C-Style null terminated string (actually, an array of two chars : { '2', '\0' }.
idineen wrote: how can i stop this number from being converted to its ascii value of 50 when passing it through the parameter.
can you show us a piece of the code by which you call the function, and how the function uses this parameter too ??
i'm quite sure you don't use it properly.

the code below is used to put a snmp object id into a pdu packet along with 3 parameters. the third parameter is used by the program to identify that the paramter is interrupted as a integer. the 4th parameter "test" is the number that i want to pass, this parameter is of type "(u_char *)" and the last is the length of the string.
snmp_pdu_add_variable(pdu, oid, oid_length, ASN_INTEGER , test, strlen(test));//
thanks
ian

Hi Idineen:
Do you have access to the source code of snmp_pdu_add_variable?
It could be that all variables are passed in as u_char*, then because of ASN_INTEGER, that function has code to convert it to an integer from the string value in test.
|
|
|
|
|
Try this:
int test = 2;
snmp_pdu_add_variable(pdu, oid, oid_length, ASN_INTEGER, reinterpret_cast<u_char*>(&test), sizeof(test));

> Should i set async read/close on the newly created socket?
The newly created socket will inherit the event mask from the server socket. It depends on the implementation of the async socket class that you use, set the events you are interested in the server socket instance and from there you create more sockets in your 'accept' handler (which will then use the same event mask).
Do not try to read data in the 'accept' handler. Have a 'read' handler which will tell you when there is (more) data available.
