Hi,

I am trying to make a custom treeview in C++ to display the shell's namespace.
It works great for all folders except physical drives and remote or network folders. I can't get the correct icons for these folders. I am using the following code snippet to load the icons for the specified folder: (Only need to obtain the icon index)

//Retrieve the icon closed for the folder

if(SHGetFileInfo((LPCSTR)lpItemIDList1,0,&fileInfo,sizeof(SHFILEINFO),SHGFI_PIDL|SHGFI_SMALLICON|SHGFI_SYSICONINDEX)==NULL)
{
lpMalloc->Free(lpItemIDList1);
lpEnumIDList->Release();

if(lpSubFolder)
{
lpSubFolder->Release();
}

return FALSE;
}

lpTreeNode->ImageIndex=fileInfo.iIcon;

//Retrieve the icon opened for the folder

if(SHGetFileInfo((LPCSTR)lpItemIDList1,0,&fileInfo,sizeof(SHFILEINFO),SHGFI_OPENICON|SHGFI_PIDL|SHGFI_SMALLICON|SHGFI_SYSICONINDEX)==NULL)
{
lpMalloc->Free(lpItemIDList1);
lpEnumIDList->Release();

if(lpSubFolder)
{
lpSubFolder->Release();
}

return FALSE;
}

lpTreeNode->SelectedIndex=fileInfo.iIcon;

The pointer lpItemIDList1 points to a piddle that contains the absolute location of the specified folder. (Relative to the root aka desktop folder)
I am only trying to display folders.

Thanks Smile | :)

Are you using MFC? Then go though the class CStdioFile, which gives easy functions to read and write text files.

hi all plz help me
i make a SDI application i dont add any code to it
now i add OncreateClient function in the mainframe class and add code as

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
// TODO: Add your specialized code here and/or call the base class
CSplitterWnd m_wndsplitter;

return m_wndsplitter.Create(this,2,2,CSize(10,10),pContext,WS_CHILD|WS_VISIBLE|WS_HSCROLL|WS_VSCROLL|SPLS_DYNAMIC_SPLIT,AFX_IDW_PANE_FIRST);
//return CFrameWnd::OnCreateClient(lpcs, pContext);
}
but when i run this no split window is opened

i try by adding an item split in the IDR_MAINFRAME menu but when i run program this split in menu is disabled
but i want to enable it and when i click it a splitter appear to split the window

What's that return written in the mid of your code.
Have you derived classes from CView ?

Listen Ashish.
What I told you yesterday was that you would need to derive classes from CView and then use CreateStatic(.....)
For example I am providing a snippet of code for splitting a window in shape of

////////////////////////////////
-------------||-----------------
------1-View-||--------2 View--
-------------||-----------------
-------------||-------------------
=================================
3 View

/////////////////////////////////

m_wndSplitter1.CreateStatic(this,2,1);
m_wndSplitter1.CreateView(1,0,RUNTIME_CLASS(COneView),CSize(200,200),pContext);
m_wndSplitter2.CreateStatic(&m_wndSplitter1,1,2);
m_wndSplitter2.CreateView(0,0,RUNTIME_CLASS(CTreeDeriv),CSize(200,200),pContext);
m_wndSplitter2.CreateView(0,1,RUNTIME_CLASS(CTwoView),CSize(200,400),pContext);
return TRUE;

///////////////////////////////////
here COneView and CTwoView were the classes that were derived from CView.

Somethings seem HARD to do, until we know how to do them.

My Code is runing. You can try.

If one of view is CFormView, you check setting Dialog of FormView, Style is Child.

I have seen how to create ActiveX from Dialog frame as

but it not a pop-up SDI window like .exe.

How to create it?

Finding the Ordinal of an imported function

capricious_0013-Jul-06 22:36

3-Jul-06 22:36

Hi guys,

I was wondering how someone would find the Ordinal of an imported function? I am using an API hook function which is below:

PVOID HookImportedFunction(const char *Dll, const char *FuncName, int Ordinal, void *Function)
{
    DWORD oldProtect;
	void *PrevValue=0;

    DWORD image_base = (DWORD)GetModuleHandle(NULL);
    IMAGE_DOS_HEADER *idh = (IMAGE_DOS_HEADER *)image_base;
    IMAGE_FILE_HEADER *ifh = (IMAGE_FILE_HEADER *)(image_base +
        idh->e_lfanew + sizeof(DWORD));
    IMAGE_OPTIONAL_HEADER *ioh = (IMAGE_OPTIONAL_HEADER *)((DWORD)(ifh) +
        sizeof(IMAGE_FILE_HEADER));
    IMAGE_IMPORT_DESCRIPTOR *iid = (IMAGE_IMPORT_DESCRIPTOR *)(image_base +
        ioh->DataDirectory[IMAGE_DIRECTORY_ENTRY_IMPORT].VirtualAddress);

    VirtualProtect((LPVOID)(image_base +
        ioh->DataDirectory[IMAGE_DIRECTORY_ENTRY_IAT].VirtualAddress),
        ioh->DataDirectory[IMAGE_DIRECTORY_ENTRY_IAT].Size, PAGE_READWRITE,
        &oldProtect);

    while(iid->Name)
    {
        if(stricmp(Dll, (char *)(image_base + iid->Name)) == 0)
        {
            //trace_printf("Found descriptor: %s\n", dhook->name);
            IMAGE_THUNK_DATA * pThunk = (IMAGE_THUNK_DATA *)
                ((DWORD)iid->OriginalFirstThunk + image_base);
            IMAGE_THUNK_DATA * pThunk2 = (IMAGE_THUNK_DATA *)
                ((DWORD)iid->FirstThunk + image_base);
            while(pThunk->u1.AddressOfData)
            {
                char * name = 0;
                int ordinal;
                // Imported by ordinal only:
                if(pThunk->u1.Ordinal & 0x80000000)
                    ordinal = pThunk->u1.Ordinal & 0xffff;
                else    // Imported by name, with ordinal hint
                {
                    IMAGE_IMPORT_BY_NAME * pname = (IMAGE_IMPORT_BY_NAME *)
                        ((DWORD)pThunk->u1.AddressOfData + image_base);
                    ordinal = pname->Hint;
                    name = (char *)pname->Name;
                }

                if(name != 0 && FuncName && strcmp(name, FuncName) == 0)
                {
                    //trace_printf("Found entry name: %s\n", ehook->name);
					PrevValue = (void*)pThunk2->u1.Function;
#if _MFC_VER == 0x0600
                    pThunk2->u1.Function = (DWORD*)Function;
#else
                    pThunk2->u1.Function = (DWORD)Function;
#endif
                }
                else if(ordinal == Ordinal)
                {
                    //trace_printf("Found entry ordinal: %s\n", ehook->name);
					PrevValue = (void*)pThunk2->u1.Function;
#if _MFC_VER == 0x0600
                    pThunk2->u1.Function = (DWORD*)Function;
#else
                    pThunk2->u1.Function = (DWORD)Function;
#endif
                }

				pThunk++;
                pThunk2++;
            }
		}
        iid++;
    }
	return PrevValue;
}

However I do not know how to get the Ordinal of a windows API function, say CreateFile or WriteProcessMemory. I know an ordinal of the function MessageBoxA is 476, but I cant find the ordinals of these functions.

Would anyone know how you would find the ordinals?

Thanks,

Robbie

Maybe the following sample function will give you some ideas?

It returns the ordinal number having the handle of the DLL (from LoadLibrary) and the address of the exported function (from GetProcAddress):

WORD getFunctionOrdinal( HMODULE hModule, FARPROC pFunction)
{
	if( hModule == 000 || pFunction == 000) return 0;

	// address of the module's export section

	ULONG export_dir_size;
	PIMAGE_EXPORT_DIRECTORY pExportDir =
		(PIMAGE_EXPORT_DIRECTORY)ImageDirectoryEntryToData(
		hModule,
		TRUE,
		IMAGE_DIRECTORY_ENTRY_EXPORT,
		&export_dir_size
		);

	// does this module have export section?
	if( pExportDir == 000) 
	{
		return 0;
	}

	LPCSTR const charAddress = (LPCSTR)hModule;

	// name of the DLL
	//LPCSTR const pDllName = charAddress + pExportDir->Name;
	// starting ordinal value. By default is 1, but is not required to be so
	WORD const base = (WORD)pExportDir->Base; // (NOTE. It is DWORD)
	// array function pointers
	PDWORD const pFunctions = (PDWORD)(charAddress + pExportDir->AddressOfFunctions);
	// array of function names
	//PDWORD const pFuncNames = (PDWORD)(charAddress + pExportDir->AddressOfNames);
	// array of ordinals
	PWORD const pOrdinals = (PWORD)(charAddress + pExportDir->AddressOfNameOrdinals);
	// number of entries
	DWORD const numberOfFunctions = pExportDir->NumberOfFunctions;
	DWORD const numberOfNames = pExportDir->NumberOfNames; // and numbers of ordinals

	for( DWORD i = 0; i < numberOfFunctions; ++i) 
	{
		FARPROC const fp = (FARPROC)(charAddress + pFunctions[i]);
		if( fp == pFunction) 
		{
			return (WORD)(i + base);
		}
	}

	return 0; // not found
}

I hope this helps.

Problems with LaserJet driver

First of all, excuse my poor English.

I have a program that fails initializing with error 0xC0000005 only if the default printer is a LaserJet Color 2605. If I select a DeskJet as default printer, there is no problem.

The program was made with VC++ 6.0 and was checked with many printers and/or platforms. Problems appeared when I bought my new LaserJet.

Thans,
