you can use ShellExecute function:
ShellExecute(hwnd,"open","C:\file_path",NULL,NULL,0)
the last three arguments specify working directory , parameters ...etc.

You can use WinExec("toto.exe",SW_SHOW);

I'm having troubles modifing the rclBounds in the ENHMETAHEADER structure. I would like to do this in memory and once done use the CopyEnhMetaFile to save it to disk.

This function seems simple enough, and does everything the SDK documentation indicates is necessary to change the selection state of an item in a list view control. After observing that it wasn't working, I added the assert in the last line of the function and sure enough, the assert fires. This makes no sense whatsoever.... Help please!
void
ListViewHelper_t::DeselectItem(int32 index)
{
LVITEM item_info;
item_info.iSubItem = 0;
item_info.mask = LVIF_STATE;
item_info.state = 0;
item_info.stateMask = LVIS_SELECTED;
item_info.iItem = index;
SendMessage( (HWND)HelperWindowHandle(), LVM_SETITEMSTATE, index, (LPARAM)&item_info );
assert( !IsItemSelected(index) );
}
bool
ListViewHelper_t::IsItemSelected(int32 index) const
{
return ( (SendMessage( (HWND)HelperWindowHandle(), LVM_GETITEMSTATE, index, LVIS_SELECTED ) & LVIS_SELECTED) == LVIS_SELECTED );
}

Rule #1 of list and tree ctrl structs: always init them to zero. The mask member is supposed to make that unnecessary, however I've seen the controls misbehave when the supposedly unused members weren't 0.
LVITEM item_info <font color=red>= {0}</font>;Give that a try.

I'd like to save a list of files into a certain directory. I used Spy++ and saw that apps use SysTreeView32. Ok, but searching for it in .NET I found nothing. Then I searched for it on Google and found that it's actually a combination of CTreeView and CTreeCtrl. Yet even with that, I don't know how to add all the directories in the system.

Can anyone Help
I am having problems adding a filter to my STL List the problem is in the function
AddFilter.
The char string FilterName is not being added correctly in the statement mfilter.push_back(FilterName);
by replacing the variable FilterName for literals there is no problem.
When debuging the previus is always the current FilterName it appears the reference the same location.
The code below shows what i have implemented please take a look and let me know where I mest up.
Any Help would be appreciated
Thanks

Are you storing raw pointers in the list? It looks like you're storing pointers instead of full copies of the strings. This would explain your problem and also explain why using statically declared strings works.
I suggest you store a string class in your list. Preferably one that is reference counted, if you're doing things like sorting the list (VC++ _bstr_t class is ref counted).
E.g.
std::list<String> mfilter

Thanks I will look for info on the _bstr_t class, this is what I want to acheive.
I have declared the list :-
typedef list<char*> FILTERLIST;
I simply require a list capable of allowing addition and deletion of strings no sorting is required. The dialog box allows the user add and remove strings from the list. The strings in the list then used with the strstr()  function one I had problems using cstring with strstr() and other variables such as static char buf[MAX_LINE_LENGTH];
// test filter option
if(prefs.filter && nFilters > 0)
{
bool found = FALSE;
int Loop = 0;
while(Loop < nFilters && found == FALSE)
{
char tmp[MAX_FILTER_LENGTH];
FilterIterator = mfilter.begin();
advance(FilterIterator, Loop);
strcpy(tmp, *FilterIterator);
if(FALSE != strstr(buf, tmp))
found = TRUE;
Loop++;
}
// display message if filter not found
if(found == FALSE)
update = AddLine( i, buf );
}
else
{
// display message
update = AddLine( i, buf );
}

In my MFC dialog program, I have a dialog box with a CRichEditCtrl on it using the dialog editor. I want to dynamically create a CRichEditCtrl just like that, but it's not looking quite right:
static (using dialog editor): http://igx89.digitalrice.com/good.jpg[^]
static code:
CONTROL "",IDC_EDIT1,"RichEdit20A",ES_MULTILINE | ES_AUTOVSCROLL | <br />
ES_READONLY | NOT WS_VISIBLE | WS_BORDER | WS_VSCROLL | <br />
WS_TABSTOP,7,18,303,238<br />
dynamic: http://igx89.digitalrice.com/bad.jpg[^]
Dynamic code:
ChatList->Create(ES_MULTILINE | ES_READONLY | WS_VISIBLE | WS_BORDER | WS_VSCROLL | WS_TABSTOP,rect,this,WM_USER+600);<br />
What am I doing wrong? I tried using GetStyle() to get the style directly from the static control and put it in the dynamic, but then the control didn't have a border!

I want to replace it by one of my own 
|
|
|
|
|
The simplest way to do this is to disable the built-in scrollbar on the list box, and then place your own adjacent to the list box. I'm not sure if even using ownerdraw you could actually replace the built-in scrollbar.

I've thought that too, but if i do, i'll have to map the mouse and key events by my own, i only want to replace the classic scroolbar by one of my own, withou mapping the events, is there another way?
|
|
|
|

Not that I know of (and I looked hard). I ran into this very problem on an application that used a touch screen. It turns out the builtin scrollbar didn't resize in a way that was appropriate for the touch screen, so I ended up building my own. I could have used the so-called 'flat scrollbars' provided by some versions of Internet Explorer, but they're not a good idea (they're no longer supported under IE6+).

At the moment I'm trying to create my own automation plugin for Photoshop. My specs: Windows 2000, Photoshop 7.0, Photoshop SDK v6.0.
The docs for the SDK are below average, especially for the info on the Action File Format, located in the doc "Photoshop File Formats.pdf" p70. I;m trying to understand the Alias structure that is placed into every photoshop action file. It makes mention of handle, FSSpec, and a windows full path. Being on a windows based pc i suspected the alias data within the action file would simply be a full path string to be read in but unfortunately the path is surrounded with rubish data that i suspect is Macintosh information.
My question is when i read in the alias structure from an action file how exactly do I parse it to create an alias property within a newly created descriptor? Or, simply what is the FSSpec format so that i can make sense of the surround rubish.
Thanks for any tips.

Hello,
I'm using a CTreeCtrl, which is processing the notify message TVN_GETINFOTIP to display an InfoTip. The tip displays a multiline description of the item in the tree, and that is working just fine. However, the InfoTip goes away on its own after a few seconds, which is often not long enough for the user to read its entire contents.
Is there a way I can increase the duration of the InfoTip, so it stays displayed longer, or until the user moves the mouse away?
Would it be a better idea for me to use a ToolTip control instead?
thanks
srs

I use Zafir Anjum's TitleTip[^] class to provide an infinitely displayed tooltip in my TakeStock[^] app. I use it to display a stock quote tooltip when the window is too narrow to display the entire quote.

If I recall correctly, there was a special type of "message box" that contained a static control, a single edit control and two push butten - OK and Cancel. This box could be used to get a single text string from the user - basically it was a "convience", thus saving the programmer from having to create a whole dialog box just to get a single text string from the user. Does anybody remember what it was called and what the MFC or API call was to access this box? I searched both the forums on this website as well as MSDN documentation and turned up nothing.
Thanks
