Cheers for the reply.
I tried that but i dont want to have to store this value anywhere and i cant guarantee a file open dialog being used before displaying my folder open dialog (which is the thing i want to point to the same location).
Any other ideas?

Okay.
Your original question was not very clear. Do you want to get the full path of the file that a user had selected via CFileDialog? Do you want to set the directory where CFileDialog first starts out?

I want to get the directory that a CFileDialog choses as its initial directory if the lpstrInitialDir of the OPENFILENAME structure is left empty.
There is an algorithm it uses to choose this directory (as explained in the OPENFILENAME documentation) but i want to be able to call a function (on something) to get me this directory without having to replicate this algorithm myself.
So i dont want to do either of what you suggested.
Cheers for your help.
Andy.

It is random. I have seen it initialize to the document directory. Other times it initializes to the system drive, C.

Are there products that contain gauge and dial widgets for use with Visual C++? I have use xDesigner (Linux) and the gauge, needle, scale, range widgets are handy to use.

There are a number of these libraries around for Windows. I think National Instruments is one company that does this. You will also find code here and on Codeguru for individual controls like guage etc. A Google search should help you find the main players in this space.

I have this situation:
I have a CDialog and in it some ctrl's. I Enumerate all the ctrl's in it to let another window take over (a CTabCtrl derived class) the ctrl's for itself - working as a delegate for the "real" other window (called Wr here) - the dialog. This I do in order to let pages of the tab-ctrl work with the ctrl-sets to mimic that the dialog is embedded into the tab. So on tab shown I go SetWindowPos(...) on all the child's etc.
I use ::SetParent(hWndNewParent, hWndChild) for taking over the ownership - all works just fine!
Now my problem: How do I STILL let the messages from all kinds of ctrls go to the Wr (dialogs in this case and later on CView's)? Say I press a btn. on tab 0 - now the BN_CLICKED generated as a result of this press go to hWndNewParent (the CTabCtrl derived) and I want to route it to the Wr. This wish is because we already have all msg-handlers installed in lots of Wr's and would like to have'm stay their - otherwise it's mixed into a CTabCtrl derived and - well; no good!
My sugestion is still to catch "all interesting" messages on the new object and then go in the direction of (pseudo): pTabDlg->PostMessage(msg)...
So in other words my CTabCtrl derived class is a delegate only. Can I do that? I can use any help I can possible get – thanks in advance!

Hi, I have a custom CTreeCtrl, the problem is that the HScrollbar is not more working correctly, because the rect of the item insert in the tree is different than the rect that i use paint. So i tried to implement my own HScrollfunction, i know the item length, and can set the Scrollbar with SetScrollInfo, that works perfectly i can also calculate the offset to scroll. I use the customdraw function to scroll the screen with setWindowOrg(xOffset,yOffset). As next i can catch nearly all mouse events and also set an offset, i have only one problem with the TVS_HASBUTTONS that is not working correctly (The offset i calculate has no influence), any idea why? Or is there another way to scroll, a custom treectrl? Is it not possible just to change the item length somehow? So the windows standard behavier of the treectrl would do the scrolling for me?
I would be happy for any help or ideas...

Make the output text of that console app into a disk file instead of printing to the command window, and then read the contents of the file into a memory buffer and parse that buffer for your needs...
But how to do this in your program? here's a solution:
Dynamically generate a .BAT batch file in your program, the contents of this batch file is like this:
consoleApp.exe >> c:\output.txt
Here, consoleApp.exe is the filename of that console app you want to capture its output, and then launch this batch file via CreateProcess win32 API. After the end of console app, what its outputs are placed into the output.txt file...
Hope this helps.

I have a function written to switch views. I have created a menu item that has two sub menu. when the application is run the default dailog comes up. when i try to switch to the other view it is not working.
here is the code for switching the view.
void CMainFrame::SelectView(int viewID)
{
// CFrameWnd* pMainWnd = (CFrameWnd*)AfxGetMainWnd();
CView* pOldActiveView = GetActiveView(); // Get current view
// Get pointer to new view if it exists
// if it doesn't the pointer will be null
CView* pNewActiveView = (CView*) GetDlgItem(viewID);
// CView* pNewActiveView = static_cast<cview*>(GetDlgItem(viewID));
// If this is 1st time around for the new view,
// the new view won't exist, so we must create it
if (pNewActiveView == NULL)
{
switch(viewID)
{
case PEOPLEVIEW: // Create a People view
pNewActiveView = (CFormView*)new CPeople;
//pNewActiveView = (CView*)new CPeople;
break;
case RELATIONVIEW: // Create a Relationship view
pNewActiveView = (CView*)new CRelation;
//pNewActiveView = (CView*)new CRelation;
break;
default:
AfxMessageBox("Invalid View ID");
return;
}
// Switching the views
// Obtain the current view context to apply to the new view
CCreateContext context;
context.m_pCurrentDoc = pOldActiveView->GetDocument();
pNewActiveView->Create(NULL, NULL, 0L, CFrameWnd::rectDefault,this, viewID, &context); // the program exits with an error at this point. please help me solve this
pNewActiveView->OnInitialUpdate();
}
// Check whether there are any orders
SetActiveView(pNewActiveView); // Activate the new view
pOldActiveView->ShowWindow(SW_HIDE); // Hide the old view
pNewActiveView->ShowWindow(SW_SHOW); // Show the new view
pOldActiveView->SetDlgCtrlID(m_CurrentViewID); // Set the old view ID
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
m_CurrentViewID = viewID; // Save the new view ID
RecalcLayout();
}

I believe you need to at least specify WS_CHILD for the style, probably WS_VISIBLE as well so you can see it.

This is how I do it.
I have two functions, one to create/add a new view to my app and the other to swap the views
void AddView(CWnd* pMainWnd, CView* pView, UINT nID)
{
CDocument* pCurrentDoc = ((CFrameWnd*) pMainWnd)->GetActiveDocument();
CCreateContext newContext;
newContext.m_pNewViewClass = NULL;
newContext.m_pNewDocTemplate = NULL;
newContext.m_pLastView = NULL;
newContext.m_pCurrentFrame = NULL;
newContext.m_pCurrentDoc = pCurrentDoc;
CRect rect(0,0,0,0);
char szTemp[64];
sprintf(szTemp, "ViewList%x", nID);
pView->Create(NULL, NULL,
(AFX_WS_DEFAULT_VIEW & ~WS_VISIBLE),
// views are created with the style of AFX_WS_DEFAULT_VIEW
// In MFC 4.0, this is (WS_BORDER | WS_VISIBLE | WS_CHILD)
rect, pMainWnd,
nID, &newContext);
pView->SendMessage(WM_INITIALUPDATE, 0, 0);
}
CView* SwitchView(CFrameWnd* pFrame, CView* pNewView)
{
CView* pActiveView = pFrame->GetActiveView();
UINT temp = ::GetWindowLong(pActiveView->m_hWnd, GWL_ID);
::SetWindowLong(pNewView->m_hWnd, GWL_ID, temp);
if(pActiveView == pNewView)
return pActiveView;
// Resize new view to fit the frame - bug fix MB 14/03/02
CRect rect;
pFrame->GetClientRect(&rect);
pNewView->MoveWindow(&rect);
pActiveView->ShowWindow(SW_HIDE);
pFrame->RecalcLayout();
pFrame->SetActiveView(pNewView);
pNewView->ShowWindow(SW_SHOW);
pNewView->Invalidate();
return pActiveView;
}
// Each view needs an ID
#define VIEWS_CALLLIST_VIEW AFX_IDW_PANE_FIRST
#define VIEWS_TRANSFER_VIEW AFX_IDW_PANE_FIRST + 1
// In the WinApp derived class, create the views
void CReceptionApp::SetupViews()
{
// Get the primary view
CView* pActiveView = ((CFrameWnd*) m_pMainWnd)->GetActiveView();
m_pReceptionView = (CReceptionView*) pActiveView;
// Create the second view
m_pTransferView = new CTransferView;
AddView(m_pMainWnd, m_pTransferView, VIEWS_TRANSFER_VIEW);
}
// Switch the view - I usually call this in the CMainFrame class
SwitchView(this, GetApp()->GetTransferView());

Hi,
Whenever a pointer is not allocated, something like this,
CClass *myObj;
It is pointing to some address like 0xccddff.
I know that the address is junk. Why it is always like 0xccdeff or 0xdeffcc?? Why it is not like 0x102033??
So, before allocation of memory it is pointing to some place, which is junk. But, where is that junk area? or which is the area used where the not allocated pointer points to?
Best Regards,
A.Ilamparithi
