Hi,

The ::SHGetSpecialFolderPath() function is available as part of Internet Explorer 4.0. I would like to emulate this function, on systems with an earlier version of Internet Explorer. Typically, I need my software to run on plain vanilla Windows NT 4.0.

I would like to know if it's possible to emulate this function using ::SHGetSpecialFolderLocation() which is available on my target platform?

The problem is :

::SHGetSpecialFolderLocation(CSIDL_APPDATA) returns an ITEMIDLIST that contains something like "Document and Settings" on my XP box, instead of something more like I would expect, something like "C:\Document and Settings\UserName\Application Data".

Should I revert to using an environment variable? Is there a better solution?

Thanks for your help.

Use SHGetSpecialFolderPath () instead of SHGetSpecialFolderLocation(). The former retrieves the path as characters where as, the latter retrieves the path as PIDL.

SHGetSpecialFolderPath() is not available on my target platform...

Do you have the following registry key?

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

If so, wouldn't a wrapper around SHGetS... that always returned a proper path, regardless of IE4 being present or not (w/o IE4, using the above mentioned registry key)?

I've got the specified registry key, but it does not contain an entry for the corresponding CSIDL_APPDATA...

Is there another way?

Thanks

I uses SHBrowseForFolder on workstations so I need to call SHGetPathFromIDList (way down in the code...). Is that one available to you?

namespace {
	int CALLBACK BrowseCallbackProc(HWND hwnd, UINT uMsg, LPARAM /*lParam*/, LPARAM lpData) {
		if(uMsg == BFFM_INITIALIZED) {
			if(lpData) {
				SendMessage(hwnd, BFFM_SETSELECTION, 1, lpData);
			}
		}
		return 0;
	}

}//ns

extern "C"  int  PickDir(const HWND  hwnd, const char* pszSource, char* pszNew/*, const char* caption*/){
	TCHAR	display_name[_MAX_PATH] = _T("");

	if(pszSource) strcpy(display_name, pszSource); 
	
	HLOCAL	hl(0);
	BROWSEINFO bi;
	memset(&bi, 0x00, sizeof(bi));
	bi.hwndOwner = hwnd;
	bi.pszDisplayName = display_name;
	bi.lpszTitle = /*caption? caption :*/ _T("Välj bibliotek");
	bi.ulFlags = BIF_BROWSEINCLUDEFILES + BIF_EDITBOX + BIF_RETURNONLYFSDIRS + BIF_NEWDIALOGSTYLE + BIF_UAHINT;
	if(pszSource && *pszSource) {
		bi.lpfn = BrowseCallbackProc;
		bi.lParam = (LPARAM)(hl = LocalAlloc(LPTR, strlen(pszSource) + 1));
		CopyMemory(hl, pszSource, strlen(pszSource) + 1);
	}
	
	LPITEMIDLIST pidl(SHBrowseForFolder(&bi));

	if(hl) {
		LocalFree(hl);
	}
	if(pidl) {
		if(SHGetPathFromIDList(pidl, display_name)) {
			strcpy(pszNew, display_name);
			return TRUE;
		}
	}
	return FALSE;
}

Difficult to understand PrintPreview without Doc/View

Yes, it seems that this function is available...
Besides, it returns the correct result.

Now, the question is, why did my code do wrong, because I could not get the correct result. For instance, your suggestion shown below works like a charm:

hResult = ::SHGetPathFromIDListW(pIDL, lpszPath);
if (FAILED(hResult))
    break;

Whereas, the code I was using does not :

IShellFolder* pIShellFolder = 0;
hResult = ::SHGetDesktopFolder(&pIShellFolder);
if (FAILED(hResult))
    break;

STRRET strInfo;
strInfo.uType = STRRET_OFFSET;
hResult = pIShellFolder->GetDisplayNameOf(pIDL, SHGDN_NORMAL, &strInfo);
if (FAILED(hResult)) {
    pIShellFolder->Release();
    break;
}

hResult = ::StrRetToBuf(&strInfo, pIDL, lpszPath, MAX_PATH);
if (FAILED(hResult))
    break;

Has anybody any hints ?

Cheers.
Maxime.

Dear Sir,

Up to now i have not realised to preview all i print(using non Doc/view system). Now I resume to learn again this .

After reading KOAY KAY HOE article and examples, i thing that what is previewing is only controls or dialog.

But what to do if I click on the button and need to preview this text " HELLO THE WORLD" for example.

I learn my self

SELECT * FROM - Tablename which has spaces

Hi,

In my vc++ application I am using Access as the database(connected using DAO). The database and tables are created during runtime.

I name the table depending upon the name the user enters. Now the problem is that if he enters a name with spaces, an errors occurs because of the SELECT sql
Say the name is : tara m

SELECT * FROM tara m

causes an error 'Syntax error in FROM clause'

But the table gets created with the correct name.
I tried putting the table name bet ' ', but it says "wrong formating in querry"

Would you be knowing the right way of doing this. Or I must ask the user to type the name without spaces?

Thanks.

I'm no SQL expert, but I think you can enclose the table name with square brackets.

SELECT * FROM [tara m]

(Still not sure why you're creating a table for each name though...)

You might post this question in the SQL forum.

Thank you. I shall check out the square brackets.

Well, the program is such that certain set of 'budget' data should be in one table. And when the user creates another 'budget' a new table with the new budget name has to be created. So if the user wants to delete the old 'budget' all I have to do is delete the table with that name. Makes life easy for me!
