No, because you have not told new how many MyClass objects to create. Since you do not know this information at the time of creation, perhaps a vector of MyClass objects would work.

Following code should be helpfull;

//... First - allocate class pointer array
MyClass **pArr = new MyClass* [dwClassCount];

//... Second - allocate class objects
for(i=0;i<dwClassCount;i++) pArr[i] = new MyClass;

//... Do the job

//... Release class objects
for(i=0;i<dwClassCount;i++) delete pArr[i];

//... Release class pointer array
delete pArr;

Merging two icons(transparent BitBlt)

I am trying to merge two icons by drawing one image transparently on another, merging the masks and creting a new icon based on the new bitmap and mask.

The code looks like this:

// Get bitmaps for both icons
GetIconInfo(hFirstIcon, &FirstInfo);
GetIconInfo(hSecondIcon, &SecondInfo);
.
// Prepare mem DCs
dcFirstIcon.CreateCompatibleDC(NULL);
dcSecondMask.CreateCompatibleDC(NULL);
dcSecondIcon.CretaeCompatibleDC(NULL);
dcSecondMask.CreateCompatibleDC(NULL);
.
// Select the Icon bitmaps into the appropriate dcs
dcFirstIcon.SelectObject(FirstInfo.hbmColor);
dcFirstMask.SelectObject(FirstInfo.hbmMask);
dcSecondIcon.SelectObject(SecondInfo.hbmColor);
dcSecondMask.SelectObject(SecondInfo.hbmMask);
.
// transparent BitBlt of one image on another (result in dcFirstIcon)
dcFirstIcon.BitBlt(0, 0, IconSize, IconSize, &dcSecondIcon, 0, 0, SRCINVERT);
dcFirstIcon.BitBlt(0, 0, IconSize, IconSize, &dcSecondMask, 0, 0, SRCAND);
dcFirstIcon.BitBlt(0, 0, IconSize, IconSize, &dcSecondIcon, 0, 0, SRCINVERT);
.
// Prepare the megred mask
...
.
// Create the new icon based on the updated bitmap and mask
FirstInfo.fIcon = true;
hMergedIcon = CreateIconIndirect(&FirstInfo);

The result is fine, but on certain icons it kills the icon shadow and makes the shadow solid black and ugly. I tried to use TransparentBlt which in those problematic icons leaves the shadow untouched but this function erases the bits where the second icon should show up and make them white.

I guess it is related somehow to XP style icons or to Alpha channel, but am not familiar with those issues and will appreciate some advice here.

It looks like you've conflicting libraries in Release build. Compare Debug settings with Release ones.

Found a similar thread[^]. It says that this can happen when you mix up the static/dll usage of MFC libraries and CRT libs. Have a look at the thread. Might be useful.

Hi!
I've created a GUI. This GUI application has one Button. In the click event of this Button, I've run another application. The second application is running as an individual window. What to do if I've to run it inside the GUI application?

I feel it like a repost.

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?

Re: I feel it like a repost.

Perspx24-Aug-08 23:39

24-Aug-08 23:39

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?

expanding tree 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
