Create some resource DLL's (dll that contains only resources without a code) for different languages. Type in CYourApp::InitInstance :

hI=LoadLibrary(....)
AfxSetResourceHandle(hI);

unfortunately switching of language on the fly without application reboot is difficult task since you must recreate all objects (menus, toolbars, dialogs and so on)

I can't offer anything more cleverly as something like that example:

//Destroy <br />
for(int i = 0; i < m_arrToolbars.GetSize(); i++) <br />
{ <br />
pToolbar = (CToolBar*)m_arrToolbars[i]; <br />
pToolbar->DestroyWindow(); <br />
delete pToolbar; <br />
}: <br />
<br />
... <br />
<br />
//Create <br />
//Let's suppose you have array with all pointers to CTollbars<br />
for(i = 0; i < m_arrToolbarIDs.GetSize(); i++) <br />
{ <br />
UINT nID = (UINT)m_arrToolbarIDs[i]; <br />
// create new <br />
pToolbar = new CToolBar(); <br />
if (!pToolbar->CreateEx(m_pMainFrame, TBSTYLE_FLAT, WS_CHILD | <br />
CBRS_TOP | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC, <br />
CRect(1,1,1,1), AFX_IDW_TOOLBAR + nID) || <br />
!pToolbar->LoadToolBar(nID)) <br />
{ <br />
TRACE(_T("Failed to create view's toolbar from Resource %d\n"), nID); <br />
delete pToolbar; <br />
continue; // fail to create this toolbar but try others <br />
} <br />
ASSERT(::IsWindow(pToolbar->GetSafeHwnd())); <br />
<br />
// set toolbar title <br />
CString csTitle; <br />
csTitle.LoadString(m_arrToolbarTitleIDs[i]); <br />
pToolbar->SetWindowText(csTitle); <br />
<br />
// cache the pointer tho the new created toolbar <br />
m_arrToolbars.Add(pToolbar); <br />
}

But it's a very little part of changing interface - only for toolbars. Similarly you should execute such operation for all objects including all dialogs. However why you should make the complications to yourself? It is easier to reboot application Smile | :)

Trouble with Serial programming in NT

I need to address the Serial (COM1) port on NT kernel based systems (NT4 and Win2k). I read the articles in the system section, but they don't seem to cover what I'm looking for.

As I want to address some hardware I made myself, I need to have full control. I.E: I must be able to put DTR on high or low at will. The articles here assume baut-rate based comminucations are the way to go.

I'd rather not use the DDK, I don't even have it.

Suggestions? Ideas?

I'm thinking about using the MSCOMM32 ActiveX control, but I'm not too happy with it. I've been looking into ::CreateFile. I can open the com port without trouble, but there isn't functionality for directly reading and writing to the port.

Please help me out,

thanks in advance and kind regards,

Griffith

After you've opened the port with ::CreateFile you can use ::WriteFile to write to the port. Use ::SetCommState to control the DTR/RTS lines, the baud rate and parity settings via the DCB structure.

If a train station is where the train stops, what's a workstation...?

Trouble with CListView

Anonymous26-Sep-02 2:44

I having trouble get any items to show in my CListView, I first tried this, from examples I found:

<br />
LV_ITEM lvi;<br />
lvi.mask = LVIF_TEXT | LVIF_IMAGE | LVIF_PARAM; <br />
lvi.iItem = index; <br />
lvi.iSubItem = 0; <br />
lvi.iImage = 0;<br />
lvi.pszText = LPSTR_TEXTCALLBACK; <br />
lvi.lParam = (LPARAM) pItem;<br />
<br />
if (GetListCtrl().InsertItem(&lvi) == -1)<br />
	return FALSE;<br />

where pItem is a struct holding info about each item, e.g. all the text for each column(i'm using report view).and I message maped ON_NOTIFY_REFLECT(LVN_GETDISPINFO, OnGetDispInfo) and had this code to set all the column text:

<br />
void CTest::OnGetDispInfo(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
	LV_DISPINFO* pDispInfo = (LV_DISPINFO*) pNMHDR;<br />
    if (pDispInfo->item.mask & LVIF_TEXT) {<br />
        ITEMINFO* pItem = (ITEMINFO*) pDispInfo->item.lParam;<br />
        switch (pDispInfo->item.iSubItem) {<br />
        case 0: // Date<br />
            ::lstrcpy(pDispInfo->item.pszText, pItem->date);<br />
            break;<br />
        case 1: // Title<br />
 	::lstrcpy(pDispInfo->item.pszText, pItem->name);<br />
            break;<br />
	case 2: // Size<br />
		::lstrcpy(pDispInfo->item.pszText, pItem->size);<br />
            break;<br />
        }<br />
    }<br />
  *pResult = 0;<br />
}<br />

Which was pretty much from an example as well, which should set thetext for each column, my problem is nothing shows up the scrollbar apears so items are getting added but no text shows. I then tried just using GetListCtrl().InsertItem(index, "") and then use GetListCtrl().SetItemText(index, subIndex, "sometext") to set each coloumn but still the scrollbar showed but no text.

Has anyone had this problem, or can give me any help, maybe i'm doing something obviously wrong, thanks for any help.

oh sorry about the loss of format.

luke. - hope that all made sense Smile | :)

hmm it said i didnt fill out some fields, but they all are... hope it works this time

creating a C Exception derived class

I cant find the implementation of say CMemoryException so I can pattern my class after it. THe .cpp files that came up in search of the MFC src folder didnt seem to have this class definition as far as I could see...

Thanks,

How do you open an inl file? Doesnt open in Vstudio...

afx.h has the class definition, definitely useful. Now i need to find the body of the class...maybe its in the inl?

Geez - did you parachuted from VB recently?

Just drag'n'drop the file or use File|Open.

Try to use Find in Files. Search in mfc\include and use CMemoryException:: (with two semicolons) as search string.

In the OnInitInstance method of your application,

replace

m_pMainWnd->ShowWindow(m_nCmdShow);

by

m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);

VC++ 7 compiler issue

I developed a COM project in VC++ 6.0 and it runs successfully. But now when i try to compile it on VC++ 7.0, the compiler is giving me strange error. Where ever there is a statement like a=22 or name = "abc", the error is reported that the symbol "=" is ambiguous. Can any one tell me whats the problem

Re: VC++ 7 compiler issue

Sas280826-Sep-02 2:57

i think it means that "=" has 2 functions in vc7. i only use vc6 so cant test it, but ambiguous means "two meanings" so my theory is that "=" can do 2 things and the compiler isnt sure what you want it to do...i wouls suggest looking it up in msdn if you have it, or if not, its at www.msdn.microsoft.com and get to the msdn libray from there to look it up.
Hope this helps,
Sas

try to typecast the value you want to assign. Sometimes a number can be of several types (int/long/...) and all those are overloaded. So you have to explicit tell the compiler which conversion to use.
e.g. if your variable a has an overloaded operator= which takes a right hand
type of int and another which takes a long, then you would have to write either a=(int)22; or a=(long)22;
Sure, it won't complain about ints and longs (internal conversion), but other types may need explicit type conversion (strings e.g. can be of many different types: unicode, utf8, chars, BSTR, ...)

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
