Nope it was a post a few days ago I think, about using ShellExecute() to execute an application, but within a dialog. I believe the answer was it couldn't be done Smile | :)

As others said on the other occasion you asked this question, as you have the source code for both applications, why not just merge the two together, so that the window in the second application is created as a child window of the dialog in the first?

No. That's not the problem. I've done it. I merged the two source codes. After that only I got two windows running separate. What to do?

What the suggestion meant was that you need to make the window for your second application a child window of the dialog in your first application, so that when you run the application, the second window runs inside this dialog. To do this you will also need to make the second window modeless and captionless. You will need to change some of your source code for this - simply merging the source won't help.

Change your design. One application cannot run inside of another in the fashion that you describe. One solution would be to change your second application to be an ActiveX control instead.

Tree view Question

Hi All!

I want on a tree control (under Win32 SDK) to retrieve item text by using NM_CLICK notification.
The problem i have is when I use NM_CLICK I retrieve NULL at HTREEITEM handle (I checked with NM_DBLCLK and i retrieved a handle).
would it be good idea to use TVHITTESTINFO with TreeView_HitTest?

The code is:

...
case NM_CLICK
{
char str[32];
int ret = 0;
TV_ITEM item;
HTREEITEM hItem = NULL;

// Get next selected item
// When i use NM_DBLCLK hItem is not NULL<-------
hItem = (HTREEITEM)TreeView_GetNextItem(hTree, hItem, TVGN_CARET);
if (hItem == NULL)
ret = 0;

item.mask = TVIF_TEXT;
item.cchTextMax= 32;
item.pszText= str;
item.hItem = hItem;

if (!TreeView_GetItem(hTree, &item))
ret = -1;
}

Thanks

There's no item associated with the NM_CLICK notification.

NM_CLICK (treeview):
"Notifies the parent window of a tree-view control
that the user has clicked the left mouse button within
the control"

What are you trying to do? Which item do you expect
to get when the user clicks the control?

Hi all,

In my application I need to open "My Network Places" in tree control. My system is on LAN and there is one share folder on server say "ShareFol". This ShareFol is password protected.
I open this share folder by Start->run->"type ShareFol here" and it ask for user name and password.
I am able to open My Network Places in my tree control and also able to get the name of ShareFol. I need to expand this folder in tree and before expanding it should ask for user name and password in the same window that I get when I open it through Start->run->"type ShareFol".
I tried it by using ShellExecute() method but when I give correct user name and password it opens ShareFol in to new window but not expand in tree.

Please give me some useful suggestions.

Thanks

Use DeviceIoControl() with the FSCTL_SET_COMPRESSION control code (documentation here).

After using CreateDirectory(), pass the directory name (and path) to CreateFile(), which will open the directory, returning a HANDLE which can be used with DeviceIoControl(). The documentation for CreateFile() can be found here.

Hi,
i try this in Windows XP Professional SP2, i have a admin rights!

Here a sample from my code:

if(FALSE == (bTrue = DeviceIoControl(
	(HANDLE) hFile,			// handle to file or directory
	FSCTL_SET_COMPRESSION,		// dwIoControlCode
	(LPVOID)COMPRESSION_FORMAT_DEFAULT,// input buffer
	sizeof(USHORT),			// size of input buffer
	NULL,				// lpOutBuffer
	0,				// nOutBufferSize
	(LPDWORD) lpBytesReturned,	// number of bytes returned
	NULL				// OVERLAPPED structure
	)))
{
	dwError = GetLastError();
}

Hi,
thank you very much for your time to help me, here is a code how i open a folder:

HANDLE hFile = NULL;
DWORD dwErr = NULL;
if(INVALID_HANDLE_VALUE == (hFile = CreateFile(
						  myfolder, // path to folder!!
						  GENERIC_READ, 
						  FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE,
						  NULL,
						  OPEN_EXISTING,
						  FILE_FLAG_BACKUP_SEMANTICS,
						  NULL)))
{
	dwErr = GetLastError();
}

and i have a valid handle, but can't access to folder!!
Next thing that make me confuse is that i can write files to folder after creation,
but can't use DeviceIoControl() --> become Errorvalue 5(access denied)!!
Just for testing i use fopen() to try to write to the new created folder and this is ok!

with best regards
termal
