I am having trouble with the behaviour of popup windows. I have a graphing program the displays 4 graphs. I want to select a graph and have it display in a new dialog, that can be moved around or minmized (much like Matlab plots)
How can I make these dialogs stop covering the main dialog and go to the back?? (they cover up the main program even if not active)
When they are minimised they do not enter the task bar but rather float above it. Is it possible to make them enter the task bar in WinNT??
I am using a new class CPopChart to start a new chart dialog from my original dialog with
class CDialog : OnPopChart() {
CPopChart pchart;
pChart.Create(IDD_POPUP,pWnd);
};

I don't know if you can make them enter the task bar, to do that they need their own WndProc. But to send them to the back use ::SetWindowPos(&wndBackMost, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);

Thanks but what I want is to send my new dialogs behind the main program/dialog , SetWindowPos() only sends them behind the other new dialogs but not the main one.

are your popup dialogs modeless?
if so is the problem you face this :- when you click on the parent window, your popups still stay on top.
Is that your problem?

Yep
Do you know a way around this??

Use GetDesktopWindow and set the desktop as the parent window of your modeless dialogs. Now you'll be able to put those popups behind your main app and you'll also be able to minimize them to the task bar

This is a facet abt modeless dialogs that a lot of people are confused about.

I've been getting into the std lib recently.
Have just been trying out map and multimap containers, and while the code compiles I get loads of warnings such as C4786. Seems to be compaining the class name is too long. Anyone experienced this, or how best to clean up code that produces this error?
I'm doing a drill down on a database using a tree control so I want to remember a simple key to locate a node I may or may not have inserted yet?
class CNodeLookup : public map<CString, HTREEITEM>
{
public:
CNodeLookup()
{
}
virtual ~CNodeLookup()
{
}
};
Thanks in advance, 
Giles

It's a known issue with VC, you just pragma the warning and it will go away ( it's not actually a problem )

I have a Warnings.h which I use to tell VC++ to STFU
example:
#pragma warning(disable:4786) // identifier was truncated to '255' characters in the browser information

if you want to get real good error messages while stl - coding go for the "stl - message - decryptor" from BD Soft
it handles all these warnings and makes the stl - related error messages much more readable..
(the article is posted on codeproject too)
the installation of this tool was a little bit a pain in the behind.. but now i think it is worth it.. i like it and would never code stl without it again..
hope this could help a little bit

Hey!
Let's say through the ClassWizard I have a variable
attached to a CEdit control. When I type a small
number (like 0.00000001), the number changes to
"1e-008" automatically, which isn't what I want.
How do I go about changing this default behavior?

Sounds like you bound a data variable (like a double, or float) instead of a control class (like CEdit), and letting MFC do the value-to-text & text-to-value conversions for you.
Bind a CEdit to the edit control, and handle the display/conversion yourself.
Or, you could write your own DDX routine to format the value as you like. Look up "TN026" in MSDN for more information.
Peace!

Here's the scenerio
I have created a app using appwiz(VC++6) and have selected the doc/view arch. Now what i'd like to have is custom app wide properties in the CMainFrame class which are modified via dialogs. The dialog is constructed as a member of CMainFrame. I can transfer data from the dialog to CMainFrame no probs, but how can i do the same for my custom CView class. CView has it's own custom members used for drawing, but part of the drawing process requires info stored in CMainFrame. You swap data between CView and CDocumnet with the GetDocument() is there anyway to get the data(custom member) from CMainFrame. I managed to used globals, but doesn't this defeat the purpose OOP? I would like a more OOD<smiles> To do this would i have to construct CView and CDocument in CMainFrame rather than settle for the appwiz default of dynamic creation using CDocTemplate() and such...?
pardon my lack of clarity
TIA

You can do this in your CView derived class.
((CMainFrame*)AfxGetMainWnd())->m_yourCustomMemberVariable;

I tried the folowing, however got a compile error
'variable' is not a member of 'CWnd'
Doesn't the following return a pointer to generic CFrameWnd rather than derived?
Any suggestion...?

Did you try (CMainFrame*)AfxGetMainWnd()->variable; ?
Jignesh

I used a cast, included the header but still came up with m_Variable is not a member of CWnd.
I even tried instantiating a new CMainFrame obj(however could do it, cuz CMainFrame has protected constructor) but then it would be a differ instance right...? which would mean incorrect data.
Is is even possible to use a object that isn't constructed as a data member from that class...? If that even makes sense...<smiles>
I can use AfxGetMainWnd() but only to call CMainFrame's native functions like resize, but the methods and members i've added in my custom class don't appear in the auto-popup...
Being that the CView,CDocument and CFrameWnd object are created dynamically at runtime via the AddDocTemplate funtion in derived app InitInstance() is there any way i can get hold of pointer to any of these objects using RTTI..?

I think you'll just need an extra set of brackets...
int viMySetting = ((CMainFrame *)AfxGetMainWnd())->m_iMySetting;
Hope this helps.

Try'd it and i finally got passed the compiler warning and had the popup assitance window show my custom members...
That worked so hopefully will the final result...haven't tested that yet...to excited, but soon
Thanx alot

Does anybody know how to get the number of arguments from a variable length function parameter list? I can't seem to find any documentation anywhere about how to get then number or arguments, without the number of args being a parameter itself.
|
|
|
|
|
You can't. The number (and type) of arguments has to be deduced from one of the non-variable arguments supplied, like, for instance, printf does with its first format argument.
