Hi

I am creating SDI MFC sample App. I followed the steps given in "http://www.codeproject.com/dialog/mdisdiapps.asp". I have not yet added any of my code.

I am getting these 2 errors while compiling:
Test_SDI\MainFrm.cpp(55) :error C2065: 'CBRS_GRIPPER' : undeclared identifier
Test_SDI\MainFrm.cpp(55) :error C2660: 'CreateEx' : function does not take 3 parameters

Any suggestions?

Thanks,
Harsha

This style comes from afxres.h, which is included automatically if you used MFC's AppWizard.

What does your project's stdafx.h file look like?

Hi it looks like this:

Look at your post and see. Notice the #include directives are not showing up. I can see them if I view the HTML source, but that's unnecessary if the post was corrected.

Hi David,

I will correct it, but then do you think that I should include afxres.h explicitly in StdAfx.h file?

Thank you.

No. It has already been included by afxwin.h.

hi all,

I set a COledateTime object:

// DateRec
COleDateTime oleDateRec;
oleDateRec.SetDateTime(anno,
mese,
giorno,
pMonitor->ore,
pMonitor->minuti,
pMonitor->secondi);

with current datetime Ex.(2006,6,20,16,50,23)

When i save oleDateRec.m_dt in a db table field with this insruction:

// Comando SQL
sSqlCommand.Format(_T("INSERT INTO STOPS_MONITOR (StopCode,DateRec,PlantCode,RoomCode,GroupCode,MachCode,CyclePos,OrderCode,StyleCode,StSize,StColor,StLot,Shift)")
_T(" VALUES(%ld,%f,'%s','%s','%s',%ld,%ld,'%s','%s','%s','%s','%s',%d)"),
lStopCode,
---> oleDateRec.m_dt,
sAffiliationPlant,
sAffiliationRoom,
sAffiliationGroup,
DbTfr.addr,
pMonitor->step,
sOrderCode,
sStyleCode,
sStSize,
sStColor,
sStLot,
atoi(tmp_Turno));

in the table STOPS_MONITOR in the field DateRec I see this: 2006, 6, 22

the day is change from 20 to 22!!!! Frown | :(

(

Database is a MSSQL Server
the field DateRec is a datetime type. lenght 8

Any idea??

thanks in advanced!! Big Grin | :-D

Too many plans make the health badly!!

Have you tested the SQL Statement in your DB environment? Does it work?

Win32 Project & ClrButton

Hi again
Excuse me for asking what I am sure is a dum question, but here goes:

I have a Win32 "Typical Hello World" project VC6.0(written by others), which I am adapting to what I want to do. In my application I wish to have coloured buttons. I have previously made use of a ClrButton class in dialog boxes (which I believe I obtained from Code Guru).

If I simply include the files CClrButton.cpp & .h in my Win32 app, I come up with errors:
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex

Can someone point me in the right direction to working out how to do this. I havnt really got a grasp of the differences in creating a dialog and a win32 app - is there a tutorial that I can look at?

Sorry for asking what I am sure are simple questions, but if you dont ask...

Cheers
Mike

Of course, tons of them. However they may not result in you understanding things any more than the sample you worked with did. Don't get fooled into believing one can "learn C++ in 21 days". For starter books on Win32 development try Petzold and Richter. There are others as well but I liked both of them.

The linking errors have to do with the libraries you are linking with. Go to your Project->Settings dialog in the C/C++ tab and select the Code Generation category. You will have a combo box with choices like "DLL Singlethreaded", "DLL Multithreaded", "Singlethreaded", "Multithreaded", etc. Try selecting the Multithreaded version. If that works, look at the code and figure out why it is creating a thread ... GUI components rarely need them.

If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

CRichEditCtrl set text color

hi all,
i need to set the entire rich edit text to white....
i know there is a SetBackgroundColor method and to set the text i need to do SetDefaultCharFormat
but this doesn't work for me....

here is what i do:

CHARFORMAT2 cf;
m_edtMsg.GetDefaultCharFormat(cf);
cf.cbSize = sizeof(CHARFORMAT2);
cf.dwMask = CFM_COLOR;
cf.crTextColor  = RGB(255,255,255);
m_edtMsg.SetDefaultCharFormat(cf);

when i start typing on the rich edit, i see the color hasn't been changed???

any help?

thanks in advanced

Actually you should put cf.cbSize = sizeof(CHARFORMAT2) before GetDefaultCharFormat, but it is even unneded in case of MFC.

May be you should also unset the CFE_AUTOCOLOR:

cf.dwEffects ^= ~CFE_AUTOCOLOR;

I think you do not need to use GetDefaultCharFormat. Maybe this will work for you:

CHARFORMAT2 cf = { 0 };
cf.dwMask = CFM_COLOR;
cf.crTextColor = RGB(0, 0, 255); // blue
m_edtMsg.SetDefaultCharFormat(cf);

Hope it helps.

excellent ! works like a charm! (i placed ZeroMemory instead of the CHARFORMAT2 cf = { 0 }; )

an other question if i may... i am interested on paiting the scroll bar myself of the rich edit

which message should i catch (when ever the scroll bar is shown ) to call the drawing of the scroll bar?

thanks again for all the help

As I know, the scroll events for rich-edit control are EN_HSCROLL and EN_VSCROLL. In order to allow these notifications, you have to set a mask in dialog’s OnInitDialog:

m_edtMsg.SetEventMask(m_edtMsg.GetEventMask() | ENM_SCROLL);

In addition the scroll bars should be enabled in the Properties panel.

If you want to change the colours of scroll bar, I think you can try the WM_CTLCOLOR or WM_CTLCOLORSCROLLBAR notifications.

If you create your own scroll-bars (for instance, derived from CScrollBar) and put them near the edit control, then the scroll notifications will be WM_HSCROLL and WM_VSCROLL .

When I display the properties of a file using Explorer,
there is often a "Summary" tab, containing information
such as Title, Subject ...

How can I read and write those properties with VC++

Thanks for any help.
