Check the return value from LoadString()

Hi,
LoadString return value is fine, it' the TB_ADDSTRING part that is confusing me!
|

From the docs:If hinst is set to NULL, idString points to a character array with one or more null-terminated strings. The last string in the array must be terminated with two null characters. Neither of your examples is right - you pass a single null-terminated string - but by sheer luck the first example is working because after your literals there happen to be two nulls.
In your second example, init your TCHAR array to all zeros before the LoadString() calls and it will work

Hi there,
We've been using VSS for a while, but the database is getting rather large and VSS is only recommended for 500 MG !
Can anyone recommand a good alternative? One that does atomic commits, has a decent gui, and has a feature to share files between projects (like in VSS).
Thanks

CVS - with the WinCVS GUI and WinMerge as the GUI diff'ing tool.

How about Subversion? it's based on CVS...
Does CVS / Subversion support sharing of files between projects? Couldn't find that in Subversion...
Cheers,

We have switched to perforce. It supports atomic commits branching and file sharing (via a branch).
It is a server/client system and is very fast.

I'm going to patent thought. I have yet to see any prior art.

I was able to test Ben Bryant's simple XML parser in a small independent project setting. But when I put in an existing larger project I get the following link errors:
Linking...
nafxcw.lib(afxmem.obj) : error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in LIBCMT.lib(new.obj)
nafxcw.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in libcpmt.lib(delop.obj)
Release/project_firm.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.
I tried undefining _ATL_MIN_CRT in preprocessor setting and other things I read on this and MS site but nothing works.
The project was compiled with multithreading, using MFC static library and VC++ 6.
Any idea? I would love to be able to use the XML Parser.

Taking a guess, some of your projects are compiled for the multithreading library, and some are not. I would make sure all of the projects and object libraries are set consistently, and rebuild everything.

Actually I built everything with multithread option and MFC static lib.
Nick Pirocanac's report points out this MSDN article
It says,
RESOLUTION
To resolve this issue, explicitly import the template class for CStringT and CSimpleStringT in the precompiled header (stdafx.h) file, as follows: template class __declspec(dllimport) CStringT<tchar, strtraitmfc<tchar,="" chtraitscrt<tchar=""> > >;
template class __declspec(dllimport) CSimpleStringT<tchar>;
I did this but it would not compile. It complains about these '<'.
From Nick Pirocanac's posting, it seems that there are different definitions of CString in more than one library.
But thanks for trying to help.

I am responding to an DTN_DROPDOWN message from a CDateTimeCtrl in order to set the day states for the Month Calendar Control that appears when you click the dropdown button. I am using the following code to set the day states, where pCalCtrl is a pointer to the Calender Control that I obtained using CDateTimeCtrl::GetMonthCalCtrl():
pCalCtrl->SetDayState(nMonths,pStates);
The problem is that I get the following line asserts from the SetDayState Function:
ASSERT(GetStyle()&MCS_DAYSTATE);
Why is this happening and how can I resolve it?
Thanks

The control does not have the MCS_DAYSTATE style, therefore setting the day states makes no sense.

How can I set the MCS_DAYSTATE flag, i have tried but i have had no luck?
|
|
|
|

void CMyDialog::OnClick( UINT uId, LPNMHDR, LRESULT * )
{
CDateTimeCtrl *pDateTimeCtrl;
CMonthCalCtrl *pMonthCalCtrl;
pDateTimeCtrl = (CDateTimeCtrl *) GetDlgItem(uId);
pMonthCalCtrl = pDateTimeCtrl->GetMonthCalCtrl();
pMonthCalCtrl->ModifyStyle(0, MCS_DAYSTATE);
...
}

The Modify style returned true, but it did not work as the line still asserted.
Can anyone find the code that creates the CMonthCalCtrl object when the dropdown button is clicked, because then I will create my own instance of CMonthCalCtrl, it is just I cannot find the code to mimic its behaviour?
Thanks

The code I provided was from a working project that does just that, except that it adds the MCS_NOTODAY style. Remember that GetMonthCalCtrl() will only return a pointer to the month calendar control while the control actually exists--that is, while it has been dropped-down by the user. Once it has been dismissed (e.g., selecting a date), the control does not actually exist.

I know that, I am using the following code in an OnDtnDropdown() message handler for my own wrapper of the CTimeDateCtrl object that is an object in my own custom Toolbar:
CMonthCalCtrl* pCtrl = (CMonthCalCtrl*) GetMonthCalCtrl();<br />
ASSERT(pCtrl != NULL);<br />
pCtrl->ModifyStyle(0, MCS_DAYSTATE);<br />
SYSTEMTIME timeFrom;<br />
SYSTEMTIME timeUntil;<br />
int nCount = pCtrl->GetMonthRange(&timeFrom, &timeUntil, GMR_DAYSTATE);<br />
LPMONTHDAYSTATE pDayState;<br />
pDayState = new MONTHDAYSTATE[nCount];<br />
memset(pDayState, 0, sizeof(MONTHDAYSTATE) * nCount);<br />
int nIndex = (timeFrom.wDay == 1) ? 0 : 1;<br />
pDayState[nIndex] |= BIT4;<br />
pDayState[nIndex] |= BIT19;<br />
pDayState[nIndex] |= BIT25; <br />
pCtrl->SetDayState(nCount, pDayState);<br />
delete [] pDayState;
However when I call pCtrl->SetDayState(), it is there that the problem occurs and it directs me to the line that asserts that i previously mentioned.
The ModifyStyle function used in the third line seems to have no effect, as I checked the return value from pCtrl->GetStyle() before and after the call to ModifyStyle and the result was the same.
By the code to create the CMonthCalCtrl I meant the code that is prewritten in the source code provided with Visual C++, not the code the user writes.
Thanks

Thanks, I haven't got time to try that tonight but I will look at it tomorrow

I have tried to destroy the control using pMonthCalCtrl->DestroyWindow() in response to the user clicking the dropdown button, however, I get an access violation when i run it, how do you destroy the MonthCalCtrl?
Thanks

Did you ever fix this problem? I am having the same problem in getting bold dates up. If you managed to destroy and recreate the window and get the dates bold I would love to know how.
Hope your still reading.
Thanks

No, I looked absolutely everywhere and tried just about everything but I eventually gave up as I couldn't find a solution anywhere. If I do have any success I will let you know, and could you do the same if you find a solution.
Thanks

I will let you know if I solve it as well.

Well I worked around it so that I can use it the way I want!
Basically I added an invisible Month Calendar control which I then set to the same space as the DateTimePickers rect in the DropDown handler. I also set a flag for bMonthShowing.
In the OnPaint method I use the bMonthShowing flag to let me know to reposition the windows
m_pMonth->SetWindowPos(&wndNoTopMost, 0, 0, 1, 1, SWP_NOMOVE | SWP_SHOWWINDOW);
m_ctlMonth.SetWindowPos(&wndTopMost, 0, 0, 1, 1, SWP_NOMOVE | SWP_SHOWWINDOW);
In the CloseUp handler I set the MonthCalendar invisible.
For the month calendar I handle the GetDayStates to set which days I want bold.
In the OnSelect for the month calendar I do the following:
COleDateTime t;
SYSTEMTIME tt;
BOOL ret = m_ctlMonth.GetCurSel(&tt);
t.SetDate(tt.wYear, tt.wMonth, tt.wDay);
m_ctlDatePicker.SetTime(t);
(If I did the GetCurSel directly into a COleDateTime it comes back with an invalid status  )
And everything works! <edit> All right I missed one or two (or more) things. oops
What a kludge!
If you want I can send you the whole dialog project. Let me know.

I just checked the result of pMonthCalCtrl->GetStyle() before and after the use of the ModifyStyle function and the result is the same. (The ModifyStyle seems to be affecting the wrong style?)
Thanks for all your help so far
