But it doesn't seem to work!! Does the following piece of code look alright ? Thanks

while (WaitForMultipleObjects(5, proHandle, TRUE, 1000) == WAIT_TIMEOUT);
{
for(i = 0; i <5; i++)
{
if(!GetExitCodeProcess(proHandle[i], &status[i]))
cerr << "GetExitCodeProccess Fail" << endl;

if(status[i] != STILL_ACTIVE )
runningProcess--;

}

printf(" %d ", runningProcess);

}

No. You have a spurious semicolon after the while condition.

After running the SQL query, we got rewsults the ADO recordset object. How can we retrieve the total number of records present in recordset object.

By searching the forums maybe? This was answered just a couple of days ago...
Anyway, the record count (rs.Count) usually isn't valid until EOF has been seen,
count reports the current number of seen records.

If you are using static or keyset cursor then the recordset count
you get from the property 'RecordCount" is valid
else you need to go from record to record manually
and then use the property.

The NMLISTVIEW struct is in your process space, the other app can't see it. Use one of the APIs designed for this purpose, mouse_event or SendInput.

Listbox w/ CEdit embeded

I have a list box which I would like to include a CEdit control to alow easy editing of fields.

So far I have embeded(composition) a CEdit control in the CListBox class and have created it in PreSubclassWindow and made it invisible. When you double click on the item the CEdit becomes visible...and when you click else where its hidden... Easy...

However I need to capture WM_SETFOCUS && WM_KILLFOCUS && WM_KEYDOWN (Return key) of the CEdit control inorder to know when to copy the contents from the CEdit control to the list item currently indexed.

I have tried:
OnCommand
WndProc
OnParentNotify

I'm doing something wrong or this is not how this is accomplished...I thought I could subclass the CEdit control with a custom WndProc, but this would require a static or global function and I won't be able to call the GetText/SetText functions of my listbox...(It's actually a custom control i've designed from scratch, not a windows LISTBOX). Big Grin | :-D

Anyways...how would I go abouts acommplishing what I want...???

Thanx

Cheers Smile | :)

Use CListCtrl not CListBox, CListCtrl supports in place-editing: LVM_EDITLABEL style

VOTD: " Yet it was the Lord 's will to crush him and cause him to suffer, and though the Lord makes his life a guilt offering, he will see his offspring and prolong his days, and the will of the Lord will prosper in his hand. 11 After the suffering of his soul, he will see the light of life and be satisfied ; by his knowledge my righteous servant will justify many, and he will bear their iniquities." - Isa 53:10-11 (NIV)

When ruuning my exe, i am getting a 'syntax error in my SQL statemnt'.
Here is the code form where the error is coming??

void CMgen1View::LoadListbox()
{

CMgen1Doc* pDoc = GetDocument();
CListBox* pLB = (CListBox*) GetDlgItem(IDC_LIST1);

CMgen1Set sect(&pDoc->m_database);

sect.m_strFilter = "InstructorID = '366'";

sect.Open(NULL,
_T( "Select * from Section WHERE sect.m_strFilter" ));

pLB->ResetContent();

while(!sect.IsEOF()) {
CString str;

str.Format(_T("%d %d"),sect.m_CourseID , sect.m_SectionNo);

pLB->AddString(str);

}
}

The problem is in your sql statement

"Select * from Section WHERE sect.m_strFilter"

The SQL server doesn't know what sect.m_strFilter means.

Try Select * from Section WHERE InstructorID = '366'

Replace

sect.Open(NULL,
_T( "Select * from Section WHERE sect.m_strFilter" ));

With

sect.Open(NULL,
_T(CString("Select * from Section WHERE ") + sect.m_strFilter ));

I am studying OpenGL and all the sample code I found so far are writen using Win32 API. I tried to integrate openGL code to a MFC SDI application, but I am having trouble with OnSize. My code doesn't behave the same as the samples of Win32 API. Anybody can give me any hint? Or some sample code to refer to?

Thank you very much in advance!

Thank you all very much. I found a sample, and I got one running in the dialog framework, which is good enough for the time being.

Again, many thanks!
