CListCtrl - FindItem - finding sub-items

Like2Byte20-Dec-06 6:56

Hi,

I've a list control I need to add some functionality to. Currently, this list stores two fields - a string field and a long.

Whenever the original programmers went searching for a single item in the list, to update that list, they searched for the string - the 0th element column - whereby FindItem returns the index val (row) of the item.

I need add a column when the app is init'd. Fine, ok. I have now a string, a long and another long(my new column).

I need to be able to search for that new column such that column 0 and column 2 return as a unique indexed item.

Base Question: How do I search for a sub-item in a CListCtrl?

Thanks, in advance.

I think you may have to iterate over the subitems and try to match/search them yourself. I do not know of a built-in way to search by sub-item.

Peace!

Program is all hosed up...need OOP/MFC help

I'd really appreciate it if someone could look at these header files and give me some idea how to fix them. Basically what I have is a tic-tac-toe program in MFC. I have a main window, which is class CGameWin (inherits from CFrameWnd) and a dialog box class called CGameKeyBindingDialog (inherits from CDialog). Previously I did almost everything in CGameWin, and everything worked out fine. Then CGameWin got bloated with functions that were related to game mechanics rather than graphics or window handling, so I decided to create the class GameOperations. It does everything for the game not related to graphics or window handling. That's when everything got hosed up. Here are the class related errors I'm getting:

game_interface.h #includes game_operations.h

and

game_operations.h #includes game_interface.h

looks like you need to remove that circular dependency: either move declarations around or use forward declarations (like you do with "class CGameWin;"), to get rid of the need to do that circular include.

#include <afxwin.h>
#include "game_operations.h"
#include <defenitions.h>

Problem with D3DFont Aliasing [modified]

Dustin Henry20-Dec-06 6:37

20-Dec-06 6:37

I am having a problem getting my D3DFonts to display antialiased. No matter what font I try to use, although some are better than others, it comes out all jagged around the edged like is is not being antialiased properly or at all.

Font creation code:

if (FAILED(D3DXCreateFont(m_pDirect3D->GetDevice(),	//D3D Device
			iSize,				//Font height
			0,				//Font width
			iWeight,			//Font Weight
			0,				//MipLevels
			bItalic,			//Italic
			DEFAULT_CHARSET,		//CharSet
			OUT_DEFAULT_PRECIS,		//OutputPrecision
			ANTIALIASED_QUALITY,	        //Quality
			DEFAULT_PITCH|FF_DONTCARE,      //PitchAndFamily
			stFace,				//pFacename,
			&font.m_d3dFont)))		//ppFont)
{
	return -1;
}

Font Display Code:

m_pDirect3D->GetFontSprite()->Begin(D3DXSPRITE_ALPHABLEND);
m_vFonts[state.m_nFont].m_d3dFont->DrawText(m_pDirect3D->GetFontSprite(), 
state.m_stText, 
-1, 
&rPos, 
state.m_dwTextJustify | DT_WORDBREAK, 
D3DCOLOR_RGBA(red,green,blue,iOpacity));
m_pDirect3D->GetFontSprite()->End();

I have tried drawing both with a Direct3D sprite and by setting the first parameter to NULL.

Any help is always appreciated.

Thanks,
Dustin

Hi.

you might check the MSDN documentation for ReadDirectoryChangesW and co. APIs.
There are also some nice articles on CodeProject discussing this:
- CDirectoryChangeWatcher [^]
- Spying a file system[^]

If your application is going to be manipulating directories as well (creating, deleting, renaming items), be sure to use the SHChangeNotify(...) function to notify the shell, if necessary.

MFC CEdit scrollbar question

FredrickNorge20-Dec-06 4:57

FredrickNorge

20-Dec-06 4:57

I constantly add more data into a CEdit, i also activated the scroll bar for this window.

When the text exceeds the CEdit text area limit, the scroll bar is activated so i can scroll the text up and down which is good.

Though instead of that i have to scroll downwards to see the new text added, is there a CEdit function which tells the scroll bar to always stay at max, or point downwards? So i have to scroll upwards instead to see the old text.

Thanks

Re: MFC CEdit scrollbar question

Robert Kuster20-Dec-06 5:37

Robert Kuster

20-Dec-06 5:37

Hi Fredrick,

I think there is no direct way. Though you could call something like this

CEdit myEdit;
CString csContent = _T("");
myEdit.GetWindowText( csContent );
myEdit.SetSel( csContent.GetLength(),
               csContent.GetLength(), 
               TRUE /* scroll to the selected text */ );

.. every time you add new text to your edit control.

Kind Regards,
Robert Kuster

Hi Robert

How do i focus it to the correct idc? i get an assert:

{ ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, EM_SETSEL, nStartChar, nEndChar);
if (!bNoScroll)

this is the code i have:

void CAutoUpdaterDlg::OnUpdateScreen()
{
char LocalBuffer[10];
itter++;

sprintf(LocalBuffer, "%d", itter);

CEdit * p = static_cast<cedit *="">(GetDlgItem(IDC_Window));
// static message for now
if(!FilesInProgress)
{
strcat(WindowBuffer, LocalBuffer);
strcat(WindowBuffer, ": ");
}
else
strcat(WindowBuffer, "");

strcat(WindowBuffer, DynamicBuffer);
int Size = strlen(WindowBuffer);

p->SetMargins(5,5);
p->SetWindowText(Convert_A_To_DA(WindowBuffer));

CProgressCtrl * progress = static_cast<cprogressctrl *="">(GetDlgItem(IDC_PROGRESS));

progress->SetRange(0,MaxRange);Progress++;
progress->SetPos(Progress);

int MemSize = strlen(DynamicBuffer);
for(int i = 0; i<= MemSize+1; i++)
{
DynamicBuffer[i] = 0x00;
}
CEdit myEdit;
CString csContent = _T(Convert_A_To_DA(WindowBuffer));
myEdit.GetWindowText( csContent );
myEdit.SetSel( csContent.GetLength(),
csContent.GetLength(),
TRUE /* scroll to the selected text */ );

UpdateWindow(); FilesInProgress = false;
}

Dear Sirs,
I am using CBitmapPicture Class implement by Chris Maunder.
After inserting bitmap image in the project as ressource and
after creating a m_picture variable, I want to load picture not using ID Ressource but using is name.

for instance, Bitmap picture is in directory c:\gestion, in name is miki.bmp.
i write m_picture.SetBitmap("c:\\gestion\\miki.bmp");

This cannot work, but if I use ID ressource it works.

what to write ?

It must work, the mistake is in the Class definition.

How to register DLL in APP path

I have a DLL in my VB application which is used by two other applications. So, i want to put the DLL in Application path and register it in Application path itself. The "DllRegisterServer" or "regsvr32" will register the DLL in System32 even if the DLL is put in Application path. Can someone please help me.Thanks in advance.

If you just want your DLL to be in a common place that other apps can find it then you
can use SHGetFolderPath() with CSIDL value of CSIDL_PROGRAM_FILES_COMMON or CSIDL_PROGRAM_FILES.

This is a more modern approach then using the path environment variable.

I forgot to mention, if you use a subfolder of "Program Files" like is typically used in
installations then your apps can use GetEnvironmentVariable()/SetEnvironmentVariable() to
set their own process PATH environment variables if necessary (to point to your common DLL
folder).

Linkage between App windows and Processes

I'm wondering if anyone knows of a reasonable way to jump from an Application Hwnd to an associated processID or vice cersa. I've found much information on enumerating either running applications (EnumWindows) or active processes (PSAPI EnumProcesses, for instance), but I can't see any way to get from a processID I'm interested in to its main window handle or from an application Hwnd to its processID (and from there to its loaded modules). Hopefully I've missed aomething obvious. Suggestions appreciated.
