Using Visual C++ 6.0 MFC in SDI application
I have a window that displays a drawing and also displays a modeless dialog window. When a user clicks on a button in the modeless dialog, I want to display a different drawing along with the modeless dialog window again. But I don't understand how to update the drawing immediately. I have a routine that gets called when the user clicks on the button, but if I simply use Invalidate(0), or UpdateWindow(), the new drawing isn't displayed until I do something on the drawing. So I'm assuming that the Invalidate(0) or UpdateWindow() are updating the modeless dialog window and not my drawing window. But I don't understand how to tell it to update my drawing window.
Thanks!

Well, assuming you dialog is child of the drawing window, whenever the button is clicked on the dialog you may call the updating functions on dialog's parent, for instance:
CMyDialog::OnBtnClick()
{
CWnd * pParentWnd = GetParent();
if (pParentWnd)
{
pParentWnd->Invalidate(FALSE);
pParentWnd->UpdateWindow();
}
}

I'm using the famous XListCtrl class in my app and currently have checkboxes as one of the subitems to indicate a state (Disabled/Enabled).
What I am currently doing is changing the background colour of a list item when Disabled is set - this works.
What I would like to be able to do is change the colour of the currently selected line (default is blue) to Red.
This is a side effect I am experiencing as when I set the disabled state of the current item in the list, the colour of the selected item is still blue based upon selection.
Any advice?
Thanks.

I have an Application that I have made a Set class called HPDset that is based from CRecordSet to connect to an ODBC database and am trying to make it work in the mainfrm class of my application. It works fine in the view class but when I add the pointer definition i get a bunch of wierd errors. It also says HPDset is undefined, but I have included the header file in mainfrm.h.
class CMainFrame : public CFOPMDIFrameWnd
{
DECLARE_DYNAMIC(CMainFrame)
public:
CMainFrame();
public:
HPDset* m_pSet;
CStringArray m_UndoString;
CStringArray m_RedoString;

If that's the case, and the code you've shown is from mainfrm.h, then it
should compile. Is namespace, spelling, and capitalization all correct?
#pragma once
#include "HPDset.h"
class CMainFrame : public CFOPMDIFrameWnd
{
DECLARE_DYNAMIC(CMainFrame)
public:
CMainFrame();
public:
HPDset* m_pSet;
CStringArray m_UndoString;
CStringArray m_RedoString;

That's an odd place for a CRecordset-based object to be.

Yes thats what I thought as well, but the other programmer that is working on this is seeting up a dynamic memory that reads in to this class. Its not recognizing my pointer as being defined.

okay what I want to do is be able to open a serial port and then set and clear the str and rts whenever I want to.
For example:
open com port
do stuff
set dtr
send data
wait so long
clear dtr
Hear is what I have tried that I thought should work:
int result = EscapeCommFunction(_hCom,SETDTR);
WriteFileEx(_hCom,"\xFF",1,test,0);
Sleep(4);
result = EscapeCommFunction(_hCom,CLRDTR);
this was unsuccessful though the EscapeCommFunction returned successful (1).
Since that didn't work I tried this
BuildCommDCB("dtr = on", &dcb);
SetCommState(_hCom, &dcb);
WriteFileEx(_hCom,"\xFF",1,test,0);
Sleep(4);
BuildCommDCB("dtr = off", &dcb);
SetCommState(_hCom, &dcb);
which was equally as unsuccessful.
What am I doing wrong?

this is going to sound so stupid. But it works now I had the OScope on the wrong pin.

One thing to note: your call to Sleep(4) will not sleep for exactly 4 milliseconds. It will probably sleep on the order of 10-20 milliseconds, depending upon the thread quantum (the thread-switching time).

I need to have my makefile select one file type(.mesh) in a data folder and then send it to a converttool.exe (in a different directory)
Does anyone know the commands I must use?
I tried searching around but couldn't find an answer. Thanks in advance.
This is what I am working with now and nothing seems to be happening (just some of the makefile)...
<br />
DATA := data<br />
OGRETOOLS := $(OGRE_HOME)/OgreCommandLineTools<br />
MESHFILES := $(foreach dir,$(DATA),$(notdir $(wildcard $(dir)
|

try this, might be because OgreXmlConverter.exe doesnot take mutiple file names in the command line
content: $(MESHFILES)
$(MESHFILES):
$(OGRETOOLS)/OgreXmlConverter.exe $@
i know gmake supports wildcard target, i don't remember the syntax, then replace the line below,
$(MESHFILES):<br />
$(OGRETOOLS)/OgreXmlConverter.exe $@
with
*.mesh:<br />
$(OGRETOOLS)/OgreXmlConverter.exe $@

I have an old MFC application that I am trying to modify. In the new code I am opening an xml file using the MSXML DOM. When I make function calls to the xml dom document I want to be able to use my help just like all the old stuff by just putting the cursor in front of the function and pressing F1 (call me old fashioned). The problem is when I do this on the xml dom functions my MSDN library does not seem to have the documentation installed and therefore the help pops up but it doesnt find my function. Does anyone know what I need to install to get this xml dom stuff in my help documentation and where to get it?
Note: I am using Microsoft Visual C++ 6.0

I have no idea but you can find the documentation you need online on MSDN. Unless you are using ATL generated classes then I do not believe there is any because the generated classes are just pass through to the COM interfaces.

Yeah the COM thing, thats what I was afraid of. I know the documentation is online but like I said I'm old fashioned and just like tp press F1 to immediately see the help for the function I am using as opposed to searching and trying to find the right instance of the function for c++\mfc

Hi,
I'm using Extended MAPI to read and create calendar events in outlook, and as far as it goes, it's working nicely. However, I can only read and write events in the default calendar, but need to be able to access any calendar the user has access to. Here's a brief code snippet showing how I access the calendar (error checking etc removed)...
m_pMAPILogonEx(NULL, NULL, NULL, MAPI_EXTENDED | MAPI_LOGON_UI | MAPI_NEW_SESSION, &pSession);
pSession->GetMsgStoresTable(0, &pStoreTable);
SPropTagArray sptaEid = {1, {PR_ENTRYID}};
SRestriction res;
SPropValue spv;
res.rt = RES_PROPERTY;
res.res.resProperty.relop = RELOP_EQ;
res.res.resProperty.ulPropTag = PR_DEFAULT_STORE;
res.res.resProperty.lpProp = &spv;
spv.ulPropTag = PR_DEFAULT_STORE;
spv.Value.b = TRUE;
SYSTEMTIME st;
pHrQueryAllRows( pStoreTable, &sptaEid, &res, NULL, 1, &pRows );
LPSBinary pEntryId = &pRows->aRow[0].lpProps[0].Value.bin;
pSession->OpenMsgStore(0, pEntryId->cb, (LPENTRYID)pEntryId->lpb, NULL, MAPI_BEST_ACCESS, &pStore);
SBinary eidInbox;
pStore->GetReceiveFolder(NULL, 0, &eidInbox.cb, (LPENTRYID*)&eidInbox.lpb, NULL);
pStore->OpenEntry(eidInbox.cb, (LPENTRYID)eidInbox.lpb, NULL, MAPI_BEST_ACCESS, &ulObjType, (LPUNKNOWN*)&pMailbox);
pHrGetOneProp(pMailbox, PR_IPM_APPOINTMENT_ENTRYID, &pCalendarEid);
The key here is that PR_IPM_APPOINTMENT_ENTRYID gives me the entry id for the default Outlook calendar. But Outlook allows me to create other calendars, and I can see them using OutlookSpy (They appear to be at the same level as the default calendar). I want to access these other calendars, but can't seem to get the entry id in order to open them. I thought I might be able to step through all the entries in the receive folder, and look for entries with PR_CONTAINER_CLASS == "IPM.Appointment", but I get an error if I try to access property PR_CONTAINER_CLASS. Another code snippet...
IMAPITable *pReceiveFolderTable = NULL;
pMailbox->GetContentsTable(MAPI_UNICODE, &pReceiveFolderTable);
SizedSPropTagArray( 2, receiveFolderTableColumns ) = { 2, {PR_ENTRYID, PR_CONTAINER_CLASS} };
hResult = pReceiveFolderTable->SetColumns((LPSPropTagArray)&receiveFolderTableColumns, 0);
SRowSet *pReceiveFolderRows = NULL;
SRow *pReceiveFolderRow = NULL;
hResult = pReceiveFolderTable->QueryRows( 100, &pReceiveFolderRows );
while( ( hResult == S_OK ) && pReceiveFolderRows && pReceiveFolderRows->cRows > 0 )
{
for( ULONG i = 0; i < pReceiveFolderRows->cRows; i++ )
{
if( PROP_TYPE( pReceiveFolderRow->lpProps[1].ulPropTag ) != PT_ERROR )
{
Write something to log file. Never gets here, as ulPropTag is always PT_ERROR
}
}
}
Does anyone know how I can access these other calendars, or have any suggestions of where I could go for help?
And as if that wasn't enough, I have a second question...
When creating an Outlook appointment, I'd like to supply an email address (or a list of addresses) and have Outlook send an email notification to those addresses. Does anyone know which properties I need to set? And do I need to separately tell Outlook to send the notification, or can it figure that out if set the appropriate properties in the appointment? So far, I've set the named property 0x823b to an email address, and experimented in OutlookSpy with various other fields, but with no success.
Any help or pointers greatly appreciated,
Regards,
Terry Smyth (Got this far, but still a MAPI novice!)

Hi everybody!
I developped an application by using c++ windows forms (msdn).
I am trying to save picture in pgm format from the picturebox of my application. I tried to modify and use the C# code provided by this link http://www.codeproject.com/KB/cs/Managed_PGM.aspx
But my application always generate a couple errors that I couldn't fix.
Thank you in advance for your help.

Can anyone help me to get the co-ordinates of a button in a dialog. I have tried with GetWindowRect and GetClientRect. Both are giving the window position only. I need the co-ordinates of a button control in a window. More interestingly, I can get the co-ordinates using the above methods for Picture control and Static control. Please advice.
Many thanks in advance.

Hello alan,
Thank you very much for your reply. Can you please tell me how to get the screen coordinates of the button.
Many thanks in advance.

For example:
RECT rect;
GetDlgItem (IDC_BUTTON1)->GetWindowRect (&rect);
ScreenToClient (&rect);

Dear Alan,
Thank you very much for your reply. I have the code below as per your guidance. But when I place the mouse over the button the Messagebox is not displayed, instead it is appearing when I place the mouse on the to area of the dialog window, but my control is placed on the bottom of the dialog window. Please advice.
void CdfdgDlg::OnMouseMove(UINT nFlags, CPoint point)
{
GetDlgItem (IDC_BUTTON9)->GetWindowRect (&rect);
ScreenToClient (&rect);
ClientToScreen(&point);
if (rect.PtInRect(point))
{
MessageBox(L"Correct");
}
CDialog::OnMouseMove(nFlags, point);
}

|

|

The line, ClientToScreen(&point); is incorrect. I think this point is already in client coordinates, so remove this line.

Hello Alan,
I tried like the below. Strangely, when placing mouse over the button changes the bitmap and when I move the mouse over the dialog the button is painted again and again. If I place the mouse over other non-bitmap button and place again over the bitmapbutton didn't change the image. That is the event is triggered for the first time only.
ON_WM_MOUSEMOVE()
ON_MESSAGE(WM_MOUSELEAVE,OnMouseLeave)
LONG CdfdgDlg::OnMouseLeave(WPARAM , LPARAM)
{
POINT point;
GetCursorPos(&point);
ScreenToClient(&point);
GetDlgItem (IDC_BUTTON4)->GetWindowRect (&rect);
ScreenToClient (&rect);
if (rect.PtInRect(point))
{
bool val=m_button4.LoadBitmaps(IDB_BITMAP4,0,IDB_BITMAP4,0);
m_button4.Invalidate();
m_button4.UpdateWindow();
}
return 0;
}
void CdfdgDlg::OnMouseMove(UINT nFlags, CPoint point)
{
TRACKMOUSEEVENT trackmouseevent;
trackmouseevent.cbSize = sizeof(trackmouseevent);
trackmouseevent.dwFlags = TME_LEAVE;
trackmouseevent.hwndTrack = GetSafeHwnd();
trackmouseevent.dwHoverTime = HOVER_DEFAULT;
_TrackMouseEvent(&trackmouseevent);
GetDlgItem (IDC_BUTTON4)->GetWindowRect (&rect);
ScreenToClient (&rect);
if ((!rect.PtInRect(point)) )
{
mouse=true;
bool val=m_button4.LoadBitmaps(IDB_BITMAP2,0,IDB_BITMAP2,0);
m_button4.Invalidate();
m_button4.UpdateWindow();
}
CDialog::OnMouseMove(nFlags, point);
}
