关于内存申请的问题

[WJN92]

在第二次执行的时候WM_KEYDOWN,即case WM_KEYDOWN结束在触发的时候,TCHAR *TempStr = new TCHAR[ 100 ] 就出错了,为什么呢?

HRESULT InsertText( TCHAR **Str,DWORD Location,TCHAR Text )
{
	if( Str != NULL )
	{
		TCHAR *TempStr = new TCHAR[ 100 ];

		delete [] *Str;
		*Str = TempStr;
	}

	return S_OK;
}
/************************************************************************************/

				case WM_KEYDOWN:
				{
					InsertText( &pTextBox->StrSource,pTextBox->CursorLocation,wParam);
					InsertText( &pTextBox->StrSource,pTextBox->CursorLocation,wParam);
					InsertText( &pTextBox->StrSource,pTextBox->CursorLocation,wParam);
					
					RECT rc = {0,0,pTextBox->Text->LabelDes.Size.x,pTextBox->Text->LabelDes.Size.y};

					pTextBox->Text->TextTexture->Release();
					
					Str2Texture( pTextBox->StrSource,_tcslen( pTextBox->StrSource ), &rc,&pTextBox->Text->TextTexture,pTextBox->Text->FontHeight,pTextBox->Text->FontWidth,DT_WORDBREAK,0,0,&pTextBox->Text->Rows,&pTextBox->Text->TextLocationArray);

					pTextBox->pCtrlClass->SetPic( pTextBox->Text->TextTexture,pTextBox->Text->idLabel );
				}
			}

(*Str) = TempStr

你不是：delete [] *Str;了么？
==============
HRESULT InsertText( TCHAR **Str,DWORD Location,TCHAR Text )
{
if( Str != NULL )
{
TCHAR *TempStr = new TCHAR[ 100 ];

*Str = NULL;
*Str = TempStr;
}

return S_OK;
}
