They appear to be. I mean, the values will remain the same if i click in the same spot, and they'll change (in what seems to be correct) if i click in a different spot.
Out of all the elements, only 3 of them end up getting a 'matching colour' when they're clicked on. The code that I've cut and pasted into these messages all looks right though doesn't it?
Maybe I'll just re-do the template bitmap or something... I don't really know what else to do.

I've just submitted an article about this. You can check out the demo files/source code at:
http://www.bj-consulting.com/tln/pte_demo.zip[^]
I didn't go the bitmap route though. It is a really nifty way of determining which element was clicked on, but if you later decided you wanted to include the dicovery date of the element (or any other text) then you would have to edit your bitmap by adding text in 117 different places and when you scaled your window the text would start to look all pixellated and illegible.
The code to draw the entire table is only 14 lines and it is scalable as you change the window size. It also highlights all of the elements in the chemical group you have selected with a red border. Right clicking an element adds it to the listbox, double clicking opens a dialog box with the chemical details. Thew controls are also resizable.
Oh - it includes an MS-Access database with the elemnt info - you'll need to create an ODBC mapping to the DB - just name the datasource PeriodicTableApp

Thanks.
I did decide on the bitmap 'route' though. Mainly because the bitmap will only have to display the element symbol (ie. H, C, etc..) and atomic number, and I only ever require to use the element symbol. I know that even in future versions of my interface, there will be no further information required...
Although I'm still having problems getting the colours to match up. It only works right for 3/92 elements (93-110 were removed because they won't ever be used for this)...

Hi all,
Got a couple of easy question for the experts. 
My first question is how do i remove the "x" box to close a modal dialog?
My second question is i want to know when using CFileDialog, is there a way to have the default file name to be incremented or have a number added to the end of it if it already exists?
If someone could show me how to do this, i would really appreciate it.

You can uncheck the System Menu option to remove the Maximize, Minimize, and close buttons. But if you want to have Max/Min buttons, then what you can probably do is to grey out the close button. For that you, just add this to the end of your InitDialog( )
VERIFY( pSysMenu->DeleteMenu( SC_CLOSE, MF_BYCOMMAND ) );
CFileDialog doesn't have any options like that. You will have implement it in your own way.

Hi,
A very simple problem yet I didn't find the solution. How can I make some buttons of the toolbar to remain pressed after the first click and came back up at the second click? Like the B (bold), I (italic) and U (underline) in Outlook, Word, etc.
Thanks

Implement the UPDATE_COMMAND_UI handler for the button, and then use pCmdUI->SetCheck ( 1 ) for keeping the button pressed, and with parameter 0 for releasing it.

how do i detect when user kills the application using end process tab in task manager.I tried using wm_queryendsession and terminateprocess but neither seems to be work?
|
|

Hi,
Just try out this.
TerminateProcess is called when one try to kill process using task manager. By default, it is not possible to kill a process that is running under a security context different than the one of the process who issued the call to TerminateProcess.
So mark ur application as service or system process. Then u may get notification if sombody tries to kill ur appln through Task Manager.

Hi,
I have a slight problem with a tree control. I cannot manage to insert items again after having deleting the whole thing.
I tried this :
<br />
HTREEITEM hMyItem = m_TreeCtrl.InsertItem( "my item" );<br />
HTREEITEM hMyChildItem = m_TreeCtrl.InsertItem( "my child item", hMyItem );<br />
<br />
m_TreeCtrl.DeleteAllItems();<br />
<br />
m_TreeCtrl.DeleteItem( TVI_ROOT );<br />
<br />
hMyItem = m_TreeCtrl.InsertItem( "my item" );<br />
hMyChildItem = m_TreeCtrl.InsertItem( "my child item", hMyItem );<br />
Instead of having "my item" as the new root in my tree, I have a blank space and no child displayed. Also, the insert functions succeed as they return a value for the items. Any ideas ?
Thanks,
Vincent

not tested but do not believe it is system problem
(1 and 2 are the same)
don't you have any own TVN_DELETEITEM handler or WM_PAINT?
is it called in one fn like displayed?
(what when you will not insert children? when you will not delete?)
t!

|

No to everything : no special handler, no subclasssing, nothing fancy, not called in any special function, just from a button's OnClick function.
When I don't delete, my new items are appended to the previous ones, ie
<br />
|-myItem<br />
|- myChildItem<br />
<br />
becomes<br />
|-myItem<br />
| |- myChildItem<br />
|<br />
|-myItem<br />
|- myChildItem<br />
<br />
as expected if you delete nothing and append to TVI_ROOT.<br />
|
|

|

can't be problem any unpair disable/enable-draw?
t!
|
|
|
|
|
<br />
void CMyDialog::OnBnClickedButton1()<br />
{<br />
m_ctrlTree.InsertItem( "toto" );<br />
m_ctrlTree.DeleteAllItems();<br />
m_ctrlTree.InsertItem( "tata" );<br />
}<br />
Here is the code, cannot be simpler ... Maybe you could try it quickly, insert a tree, associate with a variable, insert a button, copy paste my code in the event handler and see what the tree looks like.
BTW, thanks for your time

Hi,
I have tested code as below and it works fine
HTREEITEM hMyItem = m_myTree.InsertItem( "my item" );
HTREEITEM hMyChildItem = m_myTree.InsertItem( "my child item", hMyItem );
// 1. I delete the items I just inserted
//--
m_myTree.DeleteAllItems();
// OR 2. (according to the MSDN that should do the same)
//--
m_myTree.DeleteItem( TVI_ROOT );
hMyItem = m_myTree.InsertItem( "my item" );
hMyChildItem = m_myTree.InsertItem( "my child item", hMyItem );
Have u checked required properties of CTreeCtrl.
I don't see any problem in your code.

Just made a test ...
works with Visual Studio 6 on another machine. Does not work on my machine with Visual Studio 2003 ! Same procedure, new MFC app with the wizards, insert a new tab control in the dialog, add a simple button, implement the event handler of the button to do: InsertItem; DeleteAllItems; InsertItem;
Glups. Does anybody have the same problem or does this just come from the piece of s**t behind my keyboard ?

How to stop other Process use ReadProcessMemory to Inject into my Process?don't use APIHOOK?
|
|
|
|
|
The only way is hooking the ReadProcessMemory system-widely and checking if a process wants to read from your process.
You could also patch the ReadProcessMemory function (patch on assembler level to immediately return), but I wouldn't do it. Patching can lead to serious problems. This would require that you need to overwrite the Windows kernels of the users, and I don't think that most users like it if their kernel is patched...
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)
|
|
|
|
|
I've not tried this so it's simply a guess. ReadProcessMemory() requires that the memory being read be accessible for read access. Otherwise, the function fails. That implies that your process could somehow "lock" its heap memory.

Hello all,
I am using context menu (with TrackPopupMenu()).
When I use it with an usual window, all is OK.
If I use it in a "real" fullscreen window, it appears only now and then.
I used SetForeGround(motherWindow) before,
and postmessage (WM_NULL, ...) after
and I still get a variable behavior.
here is the code:
SetForegroundWindow(myHwnd);
int result = TrackPopupMenuEx(myMenu,TPM_RETURNCMD|TPM_TOPALIGN|TPM_LEFTALIGN|TPM_RIGHTBUTTON , pt.x, pt.y, myHwnd, NULL);
PostMessage(myHwnd, WM_NULL, 0, 0);
I also use fileDialog the same way (with setforeground and postmessage), which does not appear when called . I managed to get focused on it, but it takes my window out of fullscreen mode.
fullscreen window is a DX or openGL render space.
Hope someone will be able to help me ?
Thanks in advance
