I think you are opening a source file(s) without a project. In visual studio you must create a project and add files to it to be able to compile. To create project use File->New->Project.

How to convert Float array to char

12-Mar-06 10:26

I would like to write values to a file, and now the member of Class A is

const valueType *getValues(int start) const
{ evaluate(); return (const valueType *)(values + start); }

I tried to use CString/_gcvt to convert it to string/charm=, but failed.
Anyone can help me how to realize it?
thanks

Hi,

I think sprintf will do the trick for your Question. I didnt try it.

#include <stdio.h>
#include <string.h>

char *DoubletoStr(char *s, double dd);

int main(void)
{
double values2[] = {34709.22, 3746.55, 23456};
char value[32];
int i;

DoubletoStr(value,values2[i]));
return 0;
}

char *DoubletoStr(char *s, double dd)
{
char *endp;

sprintf(s,"%f",dd);
for(endp = s+strlen(s); endp!=s;endp--)
{
if(*(endp-1) != '0'&& *(endp-1) != '.')
{
*endp = '\0';
break;
}
}
return s;
}

Good Luck.

Helping others satisfies you...

not sure I understood the problem. if you have an array and you want to simply DUMP it to a file, you don't need to do any convertions. the data (in the memory) is already stored in bytes (and bytes are the same, memory wise, as chars). just use the sizeof(float) * the number of elements, and cast that array to a char* variable.

If you want to convert the data to a text data, you'll need to format it. either use CString, of sprintf

Hope this helps.

yes. develop your DLL to use the other DLL the same way you would if you were write an EXE to use the other DLL

Modify text bug in a CRichEditCtrl

HPitro12-Mar-06 7:05

12-Mar-06 7:05

I try to edit xml UTF-8 documents using a CRichEditCtrl. If I set the text without the magic code for UTF-8 it's all ok, but I cannot see UTF-8 characters from cyrillic codes correctly. Ok, using the magic code in front of the text the characters are shown correctly. The control removes the magic code itself.

But: If I use the magic code, the character at 0x1FFB and each 0xFFFE further is destroyed. I've checked that with SetWindowText() and GetWindowText(). The size is set using LimitText().

I've checked that with "RICHEDIT", "RICHEDIT20" and the RichText-ActiveX-Control. With VC 6.0 and VC 8.0. Always the same behaviour.

Anyone told me this bug had the RICHTX32.OCX before Windows 2000 SP4 too (belongs to insert or delete characters from the control). But it's now solved.
I cannot use the ocx. It seems the bug is in CRichEditCtrl(2).?

Thanks for any help.

P.S. The program itself doesn't use UNICODE.

You have to create an installer package. There are many programs out there for doing this, I use InnoSetup[^].

Right click on listview item display context menu

12-Mar-06 5:42

Hi
I have a listview control, created with single selection, the list contains the names of printers, port names etc. When I right click an item how can I display the context menu that is displayed when you right click a printer object in Printers and Faxes ? i.e the user sees the same menu to be able to delete/rename printer, click the properties item etc.

I'm using Visual C++ 6.0 on Windows XP, and know how to obtain a handle and open the printer in question and use the PrinterProperties call, but I want to display the menu as you can in Printers and Faxes.

Thanks in advance

I have not written any code yet to process the right click, all I want to do is what Printers and faxes does i.e displays menu with Open, Printing Preferences..., Properties etc, remember my list control with only contain a text item, which is the name of the printer. Therefore I can obtain server name etc and use OpenPrinter to obtain a handle etc.

if you want to view Context_menu in the right click

CMenu menu;
menu.LoadMenu(IDR_MAINFRAME);
CMenu *pContextMenu=menu.GetSubMenu(0);
BOOL o=pContextMenu->InsertMenu(0, MF_BYPOSITION | MF_STRING | MF_DISABLED, 0, "StL OBJECT");
pContextMenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_LEFTBUTTON|TPM_RIGHTBUTTON,point.x,point.y,AfxGetMainWnd());

/*{
CPoint point;
GetCursorPos(&point);
}*/

this section BOOL o=pContextMenu->InsertMenu(0, MF_BYPOSITION | MF_STRING | MF_DISABLED, 0, _T("or anything"));
I reply to question and this is here it can to delete

Browse network neighborhood

Hello,
I am to do something as simple as browse the network neighborhood and return the path selected... After a bunch of research the only thing I found that really fits my needs is an article by Paul DiLascia.

http://msdn.microsoft.com/msdnmag/issues/05/06/CAtWork/

Anyway, I am trying to modify his code to only display the network neighborhood and nothing else... He provides 2 functions for filtering out items. I have been playing around with this for hours and I can't seem to figure it out. Can anyone help me out? I only want to display the network neighborhood.

// Used for custom filtering. You must override to specify filter flags.
HRESULT CFolderDialog::OnGetEnumFlags(
	IShellFolder* psf,		// this folder's IShellFolder
	LPCITEMIDLIST pidlFolder,	// folder's PIDL
	DWORD *pgrfFlags)		// [out] return flags you want to allow
{
	BFTRACE(_T("CFolderDialog::OnGetEnumFlags(%p): %s\n"),
		psf, GetPathName(pidlFolder));

	return S_OK;
}


// Used for custom filtering. You must override to filter items.
HRESULT CFolderDialog::OnShouldShow(
	IShellFolder* psf,		// This folder's IShellFolder
	LPCITEMIDLIST pidlFolder,	// PIDL for folder containing item
	LPCITEMIDLIST pidlItem)		// PIDL for item
{
	BFTRACE(_T("CFolderDialog::OnShouldShow(%p): %s: %s\n"), psf,
		GetDisplayNameOf(psf, pidlFolder, SHGDN_NORMAL),
		GetDisplayNameOf(psf, pidlItem, SHGDN_NORMAL));

	return S_OK;
}

Actually I have to override these functions.. Here is the following but I am still unsure on how to filter...

//////////////////
// Get flags for custom filtering: Only enumerate folders. This is only
// called when custom filtering is used.
//
HRESULT CMyFolderDialog::OnGetEnumFlags(IShellFolder* psf, LPCITEMIDLIST pidlFolder,
	DWORD *pgrfFlags)
{
	BFTRACE(_T("CMyFolderDialog::OnGetEnumFlags\n"));
	
	*pgrfFlags = SHCONTF_FOLDERS; // show only folders
	
	return S_OK;
}

//////////////////
// Determine whether to display item: doesn't actually do anything, just
// illustrates the function in action through TRACE diagnostics.
//
HRESULT CMyFolderDialog::OnShouldShow(IShellFolder* psf,
	LPCITEMIDLIST pidlFolder,
	LPCITEMIDLIST pidlItem)
{
	BFTRACE(_T("CMyFolderDialog::OnShouldShow(%p): %s: %s"),
		psf, GetPathName(pidlFolder), GetDisplayNameOf(psf, pidlItem, SHGDN_NORMAL));

	SFGAOF attrs;
	psf->GetAttributesOf(1, &pidlItem, &attrs);
	BOOL bShow = attrs & (SFGAO_FILESYSTEM | SFGAO_HASSUBFOLDER);
	
	BFTRACE(_T(" [attrs: %08x]: %s\n"), attrs, bShow ? _T("Yes") : _T("No"));
	

	return bShow ? S_OK : S_FALSE;
}

Use SHGetSpecialFolderLocation() with the CSIDL_NETWORK flag to get the PIDL of the Network root folder, then pass this PIDL to SHBrowseForFolder() as the pidlRoot member of the BROWSEINFO structure. This will force the "Browse For Folder" tree to be rooted at the root network folder.
