I've some toolbars in the same frame; if I try to dock all of them in the same border (i.e. TOP), i would like that they appear on the same line (as when you open Word) instead that having one line for any Toolbar.... the user can drag and move them in the same line, so I think that it should be possible....
|

|
|
|

I think that it should be possible even without a CRebar (it doesn't allow floating ControlBars)...
I tryed also using the CBRS_FLOAT_MULTI style but it seems not to work...
When it starts bars are positioned in this way:
[BAR1]
[BAR2]
[BAR3]
What I want is thatm the first time the program is run, the bars appear in this order:
[BAR1][BAR2][BAR3]
If the user move them and I save the status, the next time they will appear correct...

Ok, here's another one about game programming. Should I stick with Visual C++ 6.0 for game design or upgrade to Visual C++ on Visual Studio .NET? Is there something new to Visual Studio .NET that would help in game programming or everything's fine with Visual Studio 6.0 and .NET is just for, well, .NET programming? Thx!

I'd imagine you'll probably want to stick with Visual C++ and avoid the additional overhead of using managed code via. the .NET framework, or calling unmanaged code from managed.
If it isn't broken, why try and fix it 
I see .NET primarily for rapid development of enterprise distributed systems, not really a games thing

I would use Use Intel's compiler. It's supposed to be quite a bit better than MSVC++ when it comes to compiling floating point code. Plus, it drops right into MSVC++ 6/.NET. It's object code compatible with MSVC++ and it supports partial template specialization.

VS.NET doesn't really provide any advantages over VS6 for writing games, apart from improved standards compliance. Nothing new has been added to support game development.

Hello,
I am using MS Flex Grid, an ActiveX control in one of my dialog boxes in my dialog based application. The OCX file for the ActiveX control is MSFLXGRD.OCX. The program works fine on my computer but doesn't work on other computers and terminates right before it gets to the dialog box with flex grid on it.
Please guide me as to how I should include the OCX file in the program so that it would work on any machine.
From the earlier posts it was mentioned that I could update the registry manually .. or include it in the setup file for the .ocx file. Unfortunately I don't have much experience with win registry. Could anyone please tell me how do I register the OCX file manually in registry ... and how do I go about including it in my setup program. I am making a setup program using Installshield for VC++ 6.0.
If you know I will also appreciate if you could direct me to some website where I can find info about adding OCX files into the registry manually and using the setup program and doing it automatically.
Thanks!
Sincerely,
Anjum.

Ok First I ll explain how it can be done Manually.
Just copy the Ocx file in the system or any directory.Then go to that directory via Command prompt.Then type the command
c:>Regsvr32 MSFlxgrid.OCX
Then ur ocx file will get registerd in the system...Its simple..
If ur using Visula install shield then Put this Ocx file and make them selfRegisted in option. Thats all
cheers,
Super

Hi!,
I need to implement a drag and drop feature to the application I'm working on, but my employer wants it to be non OLE as OLE would... blah blah... I explored the way of receiving files using WM_DROPFILES, but how about sending them without OLE? Yes, I have RTFM and the Clipboard section of CodeProject.com
Thanks in advance
|

There used to be an old "trick" before OLE was
widespread to achieve this..you basically need to fake
the WM_DROPFILES message yourself, using the following method:
(sorry, but any code I might have had to do this would
have been lost a long time ago
In your WM_MOUSEMOVE handler (or however you are doing
the dragging bit), make a routine that checks to see if
the window underneath the mouse has the WS_EX_ACCEPTFILES extended style set.
i.e.
<br />
POINT pt;<br />
HWND hwnd, hwndTop;<br />
<br />
pt.x = screen_mouse_x<br />
pt.y = screen_mouse_y<br />
<br />
hwnd = WindowFromPoint(pt);<br />
<br />
<br />
if(GetWindowLong(hwndTop, GWL_EXSTYLE) & WS_EX_ACCEPTFILES))<br />
return TRUE;<br />
else<br />
return FALSE;<br />
get the idea..? It's a good idea to only do this when the current window under the mouse has changed - no need to keep doing this same logic over-and-over..
Now you know if the window under the mouse accepts files - so, you can change your mouse-cursor to reflect this. When your release the mouse, reset the cursor, and send a fake
WM_DROPFILES to the top-level window:
You need to use two undocumented APIs to do this. These
APIs are called DragInitBlock and DragAppendFile, which you
use to create a structure used to pass to the WM_DROPFILES
call. I did a quick search on the net, and came up with this:
http://www.tec.puv.fi/~kimmos/News/031
Seems to be a pretty good example for how to do it, so I'd
take a look there..

I added a new indicator panel to the status bar. I wanted to update it with the UI Update handler so I put the stuff in the message map and the afx_msg in the .h file of the mainframe. This created the panel but didnt update it with the SetText I did in the UI handler. I then put the exact same stuff into the view class instead and viola, the new panel gets updated etc.
Why does it work when handled in the view but not in the frame? I used pCmdUI_>SetText("new") in both handlers and it only worked when handled in the view.
Thanks,
ns
(I also found out about SetPaneText but thats not at issue here)

Hello,
I'm currently using VC++ 6.0's wizard function OnDblclk(NMHDR* pNMHDR, LRESULT* pResult), but how do I detect here if the ALT key is being held down? I cannot seem to find the right spot in my MDSN search to get this information. Thanks!

Thanks for the tip. I could not find the ALK key in the virtual key typedefs, but I did find VkKeyScanEx() through the MSDN links. That function seems to have a way to read the ALT key state.

it's called VK_MENU (not VK_ALT)

I use this class in an app to format strings.
But, when I exit the app in debug mode, I see the strings that I formatted as memory leaks. What should I do to remove these memory leaks?
now the code looks like this:
void function()
{
std::strstream ostr;
ostr << "This is a test" << std::ends;
// i use the ostr
// i assumed that the cleanup would happen when function quits
// but when i quit the app, I can see the "This is a test" in object dump
}

Don't use strstream it is outdated now. use stringstream

I have created a regular dll which export the function
__declspec(dllexport) BOOL Extract(PCLTextList *pList);
A create and pass to the dll the pList pointer from a Dialog Based application . When I call delete PList from this app an ASSERTION FAILED Error appears at this function:
_CrtIsValidHeapPointer
Does anyone know why?
Plese help if you can
Thanks

Correct me if i am wrong:
someone creates a list object , sends it to your dll and you fail to delete that object.
If that so, then check whether your run-time library and the caller run-time library are the same.
For example, if your run-time library is Multithread Dll (/MD) and the caller run-time library is Multithread (/Mt).
Check what happens when the caller's project and your project have the same run-time library.

Uh, oh - this works only if both the .dll and the .exe use the same DLL-Version of the CRT. It will fail if they are linked against the static version.
The reason is the following: The CRT contains a heap manager, which implements operators new and delete. If you link the CRT statically to a module (.exe or .dll) the heap manager is also linked to your module, meaning that each module contains its own heap manager. It is not possible to allocate memory from one heap manager and delete it with another one - they don't know of each other and the memory just looks invalid to them. And this is what happens in your project.
However, if both, the .dll and the .exe are linked to the same DLL-Version of CRT, they share the same heap manager (because the CRT DLL is loaded only once into the process' address space). Then all ressources (memory, open file handles, etc.) are interchangeable between the modules.
To avoid this messy details it is common and good practise to destroy resources always in the same module they have been allocated. Then the used CRT version does not matter and you are always on the safe side
