tmpProcess = new Process();
tmpProcess.WaitForInputIdle();
tmpProcess.StartInfo.FileName="f:\\mirc59t";
try{
tmpProcess.Start();
while(! tmpProcess.Responding)System.Windows.Forms.Application.DoEvents();
}catch{}

tmpProcess.WaitForInputIdle();
IntPtr hWnd=tmpProcess.MainWindowHandle;
Srm=new send_recive_messages(hWnd);
/*/////////////////////////////////////////////////////

//////////////////////////////////////////////////////////
HWND h=::FindWindowEx(hwnd,0,szBuffer1,szBuffer);

h variable recive zero that's why remaining code could not run.

it should not recive zero because the process main window

Maybe calling GetLastError() after FindWindowEx() might shed some light on things?

FindWindowEx needs the caption/class of the child window. You're passing caption/class of main window.

Can't you just use GetDlgItem? You know the IDs of child windows, don't you?

Hey Guys

I have a CView dirived class i am using as my main view in an MDI application and i have a CWnd derived class which is a control i am writing how do i get the control to be drawn inside the CView Class i have tried BeginPaint and Print with no luck. At the moment i create the control in the create part of the CView and then check for a safe handle in the paint of teh cview before calling BeginPaint of the control which doesn't work.

Cheers Peter

If you have created you CWnd derived control as a chile window of the CView, then as long as its visible and withoin the CView's client area then it should appear. Make sure when creating the control that the WS_CHILD and WS_VISIBLE style have been set.

For example, in one of my apps, I create a list of controls like this:

m_Log.Create("Log window", WS_CHILD | WS_VISIBLE | SS_SUNKEN | SS_CENTERIMAGE | SS_NOTIFY| WS_CLIPSIBLINGS, CRect(10, 10, 100, 100), this, IDC_EDIT1) ;
m_WhizWheel.Create("Wheel", WS_CHILD | WS_VISIBLE | SS_BITMAP | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 20, 20), this, IDC_WHIZ_WHEEL) ;
m_WhizWheel.SetBitmap(m_WheelBitmap[m_BitmapIndex]) ;
m_TrayProgress.Create(WS_CHILD | WS_VISIBLE | PBS_SMOOTH | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(10, 10, 15, 100), this, IDC_TRAY_PROGRESS) ;
m_SampleProgress[0].Create(WS_CHILD | WS_VISIBLE | PBS_SMOOTH | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(20, 10, 25, 100), this, IDC_SAMPLE_PROGRESS1) ;
m_SampleProgress[1].Create(WS_CHILD | WS_VISIBLE | PBS_SMOOTH | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(20, 10, 25, 100), this, IDC_SAMPLE_PROGRESS2) ;
m_SampleProgress[2].Create(WS_CHILD | WS_VISIBLE | PBS_SMOOTH | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(20, 10, 25, 100), this, IDC_SAMPLE_PROGRESS3) ;
m_SampleProgress[3].Create(WS_CHILD | WS_VISIBLE | PBS_SMOOTH | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(20, 10, 25, 100), this, IDC_SAMPLE_PROGRESS4) ;

m_ValveStatus.Create("?", WS_CHILD | WS_VISIBLE | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 15, 15), this, IDC_VALVE_LED) ;
m_DadStatus.Create("?", WS_CHILD | WS_VISIBLE | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 15, 15), this, IDC_DAD_LED) ;
m_LampStatus.Create("?", WS_CHILD | WS_VISIBLE | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 15, 15), this, IDC_LAMP_LED) ;
m_DeviceStatus[0].Create("?", WS_CHILD | WS_VISIBLE | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 15, 15), this, IDC_DEVICE1_LED) ;
m_DeviceStatus[1].Create("?", WS_CHILD | WS_VISIBLE | SS_NOTIFY | WS_CLIPSIBLINGS, CRect(0, 0, 15, 15), this, IDC_DEVICE2_LED) ;

I then later on use MoveWindow() on each of the controls to place them exactly where I want them to be.

Try GetSystemMetrics or SystemParametersInfo with SPI_GETNONCLIENTMETRICS.

STL: get range where...

Hi,

I'm trying to "plug together" some STL, but I don't get along with it:

I have a sorted array of int's,
I want to find the index range where the values fall in a certain range

in: int * array, size (sorted)
minval, maxval

out: minidx, maxidx, so that minval <= array[minidx..maxid] <= maxval

Any STL gurus around?

TIA
Peter

Searching in a CListCtrl

I am currently using the method CListCtrl::FindItem() to search in the first column of a CListCtrl. Is it possible to search through another column than the first one?

I also committed the crime of posting a programming question in the Lounge.

AFAIK, your only option is iterating over all items and checking each with GetItemText.

progress bar from CView

Hi,

Can someone tell me how to access the progress bar in status bar from CView.

for example, the following code is not showing any activity in the progress bar Cry | :((

CMainFrame* cfm = (CMainFrame*)AfxGetMainWnd();
cfm->StatusBarMessage("Link Verification going on...");
for( int i=0; i<800; i++ )
{
Sleep(10);
cfm->m_ctrlProgress.SetPos(i);
}

StatusBar Message is shown, but not the activity in the progress bar.

thanx in advance...

Use Invalidate/UpdateWindow to refresh the progress bar. Your loop doesn't service message queue, windows do not repaint themselves.

{

pTI->hwnd = m_hWnd;
//
-->??? pTI->uId = ???????????????????????????;
pTI->lpszText = LPSTR_TEXTCALLBACK;
pTI->rect = rect;
return pTI->uId;

return CFlextable::OnToolHitTest(point, pTI);

Thank you for any help!

Hi
just implement it in your app's view-class. Just add a line in the OnInitialUpdate:

CMyView::OnInitialUpdate()<br />
{<br />
  SetWindowText("This is my child window title!");<br />
  CBaseClassView::OnInitialUpdate();<br />
}

Hope this helps!
