Since the structure is declared in someother file, and used as extern in other files or function, the memory is still allocated to the structure, if the function is making a copy of the structure into its stack then its a different thing, but the original structure has been memory preallocated.

hi everyone,
I know, I already asked about that topic, but I still can't get it to work.
the problem was that i want the dialog opened by SHBrowseForFolder() to get opened on a specified folder.
here is the code i wrote :
void CFileRenamerDlg::OnBrowseFolder()
{
CoInitialize(NULL);
char folderBuf[MAX_PATH];
LPITEMIDLIST pidl = NULL;
BROWSEINFO bi;
bi.hwndOwner = this->GetSafeHwnd();
bi.pidlRoot = pidl;
bi.pszDisplayName = folderBuf;
bi.lpszTitle = _T("Select the folder where your files are located in...");
bi.ulFlags = BIF_NEWDIALOGSTYLE | BIF_RETURNONLYFSDIRS | BIF_SHAREABLE;
bi.lpfn = NULL;
pidl = SHBrowseForFolder(&bi);
if (pidl != NULL) {
SHGetPathFromIDList(pidl, folderBuf);
m_Directory.SetWindowText(folderBuf);
m_strFolder = folderBuf;
}
}
for your information, m_strFolder is declared as a CString.
this compiles fine, but always starts on the desktop. if I uncomment what is commented, the compiler (VC7.1) complains about the A2W() macro (actually, not directly the macro, but the "variables" used within).
did anybody already encountered this ?
can anyone suggest a better way (if any) to get SHBrowseForFolder() to get opened on a specified folder ?
thanks in advance.

Try the newer improved CA2W macro. Actually I think you need CT2W macro. The correct shortest usage:
::SHParseDisplayName(CT2W(m_strFolder), . . .
Then try the rest of the code again. I hope this helps.

|

thanks for you answer. however, I have to add some more details.
actually, my A2W() was a mistake when I posted the message. I actually used T2W(), but not CT2W() because SHParseDisplayName() waits for a LPWSTR.
hum, not i'm checking the msdn and it tells me a LPCWSTR, but intellisense was telling LPWSTR. which to believe, and how to solve that ?
|
|
|
|
|
Since SHParseDisplayName requires LPCWSTR, the proposed solution should work:
::SHParseDisplayName(CT2W(m_strFolder), . . .);
|
|
|
|
|
yup, I think so (but i have no compiler for the moment, so I'll give you feedback tomorrow when I test it at home.
By the way, why does intellisense tell me SHParseDisplayName() wants a LPWSTR then ?

I cannot explain this. In my case it tells me that the first parameter is of PCWSTR type.

Because that is the way the function is defined. 
|
|
|
|
|
did you read the other posts of the thread ?
boths ways are how the function is defined ! the problem is one is the doc online, and the other is what i'm using in my code.

super_ttd wrote: boths ways are how the function is defined
My point is as far as the compiler knows, at the point of the call there is only 1 definition.
Are you sure you didn't see LPCWSTR with intellisense? Same thing as PCWSTR.
I can't find any old reference (in header files) to SHParseDisplayName() taking anything but
a const WCHAR * as the first argument. The L part of the macro is a holdover from Win16 days.

hello Viorel,
then i tried your sample, and it does compile.
but the behavior is not the one expected. 
actually, it does open the "browse for folder" dialogBox, but the folder in m_strFolder is drawn as the root folder.
what i wanted to have is still have the desktop folder as the root (exactly as if pidl was set to NULL), but with m_strFolder folder selected (the tree expanded to that folder).
another weird thing is that SHParseDisplayName() is available only since WindowsXP. wasn't it possible to have such a behavior on Windows 2000 ?! 
thanks for your contribution...  see you

Hello Comunity,
i use this funktion to show items in an CListCtrl with diferent colors, and i need to know
which item number is to be drawn.
I try to cast pNMHDR to
LPNMLVCUSTOMDRAW pLVCD = (LPNMLVCUSTOMDRAW)pNMHDR;
but i need to know the itemnumber who is to drawn...
any one have some sugestions for me?
thaks
break;

If no other solution, I think you can store the item number as a private data:
lvItem.mask = ... | LVIF_PARAM;
. . .
lvItem.lParam = (LPARAM)i;
pMatrixListResults->InsertItem(&lvItem);
Later obtain this number from the NMCUSTOMDRAW structure:
LPNMLVCUSTOMDRAW pLVCD = (LPNMLVCUSTOMDRAW)pNMHDR;
int number = (int)pLVCD->nmcd.lItemlParam;
I hope this works.

Hello,
yes, your idea works perfect, this is what i use now!
Thank you!

Why don't you use OnDrawItem?
|

Hello Capallini,
i never use this method, maybe i should try this.. 
regards
break;
|
|
|
|
|
LPNMLVCUSTOMDRAW pLVCD = (LPNMLVCUSTOMDRAW)pNMHDR;
int nItem = (int) pLVCD->nmcd.dwItemSpec;

ups,
yes, you right, i use this before in my previous project, thanks... :->

I doubt if this is possible. I don't think you could disable specific items in a CComboBox.

you have to subclass the CComboBox for same.. subclassing is the key to this type of effect

Hi all,
I have an application written in Visual C++6.0 which uses a Rich Edit Control to display user chat. I want to implement text highlighting as in MS Word for this rich edit control so that I can highlight messages from particular players.
I am using CHARFORMAT structure for formatting text. Can someone help me implementing this?
I tried using CHARFORMAT2 which has text BackColor property but it didnt help.
Thanking in anticipation

CHARFORMAT2 cf;
memset(&cf, 0, sizeof(CHARFORMAT2));
cf.cbSize = sizeof(CHARFORMAT2);
cf.dwMask = CFM_BOLD;
cf.dwEffects = CFE_BOLD;
COLORREF clr =RGB(255, 10, 15) ;
cf.dwMask =CFM_COLOR;
//cf.dwEffects = CFE_AUTOCOLOR; // Bold
cf.crTextColor = clr;
