Here is my situation, I am using GetDiskFreeSpaceEx to grab drive information from mulitple servers across the network. When for some reason or another that the server is down/unavailable, it can take GetDiskFreeSpaceEx up to 60-180 seconds to "TimeOut". Does anyone know how to change the time out value or how I should go about implementing some timeout code?
Environment VC6
Platform writing for: NT4, W2K, XP
Thanks in advance.

Hi guys,
is there anybody who has examples of W2K power management/power options?? I would like to know how to implement functions like "stand by", "hiberate", etc. Thanks in advance.

I remember that there is a Windows API to immplement your wanted function.I am sorry that I had forgot the function name ,maybe "ShutdownWindows",you can search it in MSDN.microsoft.com

Hi,
I created an instance of my CFrameWnd-derived class with:
CRuntimeClass* pRuntimeClass=RUNTIME_CLASS(CMainWindow);
CObject* pObject=pRuntimeClass->CreateObject();
ASSERT(pObject->IsKindOf(RUNTIME_CLASS(CMainWindow)));
CMainWindow* mainWindow=(CMainWindow*)pObject;
How can I destroy this object at the end of my application?
delete mainWindow does obviously not work. Is there maybe a function similar to CreateObject() which destroys it?
Thank you
|

Thank you for your reply.
I also thought that the window would automatically get destroyed, but in debug mode it tells me that it detected memory leaks (the CFrameWnd and its toolbar)
|
|
|
|

IMO the automatic memory leak detection detects more than is there.

In debug mode I checked if the destructor is called, and it is not called.

Greetings,
I am embedding a .pdf file in my executable by using a custom resource ("PDF"). At runtime, I can extract this using the usual LoadResource() stuff and saving as a temp file and then running ShellExecute() on that file. This works, but leaves a temp file around. Not tidy.
What would be nice is being able to do something like:
ShellExecute(..., "res://program.exe/PDF/mypdffile.pdf", ...)
Unfortunately, this doesn't seem to work (at least not on Win2000 using IE6). I get a message from IE saying the page couldn't be loaded.
Doing something like:
ShellExecute(..., "res://program.exe/myhtmfile.htm", ...)
works as expected. Which would tend to prove that I've got the basic motions working OK.
I saw a blurb on MSDN saying that the res: protocol didn't work properly for non-HTML resources, but the implication was that this was a bug in IE4.
Any ideas on what I am doing wrong?
Thanks!

I have an MDI app whose title is specified as the string resource AFX_IDS_APP_TITLE (eg: "MyApp"). I want to generate the app's title dynamically, based whether the app is running in "Lite" or "Professional" mode.
The following advice from MSDN appears to not work. The app still uses "MyApp" inspite of the following code in CMyApp's constructor.
free ((void*) m_pszAppName);
if (isLiteEdition())
m_pszAppName = _tcsdup (_T("MyApp - Lite"));
else
m_pszAppName = _tcsdup (_T("MyApp - Pro"));
Any clues would be appreciated. Thanks,

works fine for me. make sure nothing else is setting that string later on...

Please stand by

Ugh - I just realized it does work fine - sort of. Message boxes generated by the app correctly use the Lite/Pro name.
Unfortunately, there's an IDR_MAINFRAME string resource (set to "MyApp") that's clobbering the mainframe's title. I can't simply SetWindowText() the custom title because my MDI frame windows use the FWS_ADDTOTITLE style which causes the window title to change to "MyApp - Doc name". Deleting the IDR_MAINFRAME resource causes document titles to be prefixed by an empty string (i.e. "- Doc name").
There must be a way to make my app use my custom title as a prefix...

Doesn't SetWindowText set the caption ?

Yes, but the caption changes because my MDI frame windows use the FWS_ADDTOTITLE style. The MSDN advice does in fact work (see my reply to Chris L's note) but every time I open a doc (or switch views), the mainframe's caption gets reset to "MyApp - Doc name".
I'd like it to use "My App Pro - Doc name" or "My App Lite - Doc name" instead.

Maybe you could trap the WM_SETTEXT for you main frame?

No, that would cause an infinite loop when I try to set the window text myself. A cheesy solution to the problem is to create a timer and reset the window text in every WM_TIMER message. Such a hack...

So just set a flag first time in so that you know not to start recursing.

What if another WM_SETTEXT arrives before mine is sent? (The app is multi threaded). No wait, that *might* work, since a message is fully processed before the next one is popped off the queue. Hmmm, now you've got me thinking.
But I must admit, this seems more of a hack than the yucky timer thang.

If it's a question of UI threads vs. worker threads, it's a non-issue - only the UI thread will ever be in there. So the only question is if you have >1 UI thread, but even then, I'm pretty sure you get 1 message queue per thread...

You think? I feel the totally opposite way. The thought of un-necessarily updating the window caption every second (or whatever) instead of once, when it is actually being set, seems really ugly.

I would only update it if necessary. I feel this is less hackish because it's more obvious. Overriding a low level handler like WM_SETTEXT seems more subtle and imho can have more side effects.
But all this may be moot. A friend @ work just informed me that he moved my original code to CMainFrame::OnCreate() which appears to have fixed the problem.  I'll let you know if this works!

You need to give us more information. The code you are doing looks fine, but it all depends on
when you are "calling" it.
If it is before the framework loads the resource string, then you are too early.
If it is after CMainFrame calls its SetWindowText, then you are too late...

Hey Folks,
I have a customer who has one of our applications crashing on his PC, but unfortuantely, I'm unable to replicate here. I managed to get my hands on his DR.WATSON .log which gives plenty of information, but how I do make head/tails of what exactly crashed in my program? I'm able to verify that it is our FTS.EXE that is crashing on his PC, but am I able to pin point it any futher as to maybe a function/line of where the problem occurs?
Any tips you can send would be greatly appreciated... HO HO HO...
Mike.

First thing to do: make a release build with debug symbols enabled. Then run it in your debugger and set a breakpoint at address 009f3d68 (significant call) and then step through the next few bytes. Then you know exactly where in your source it crashes. It might not reveal the reason but the location.
Make sure your app relocates to 0x009d0000 by setting the relocation address in the linker settings. (Or just calculate the offset: your app's loadaddress + (0x009f3d68-0x009d0000) = breakpoint)
Also note the NULL return address on the stack. Your stack is gone at this point.
I don't think this is a serious possesion, and the evil most likely comes from your hand. Colin J Davies, The Lounge

Hi --
I have a simple question about dynamic memory and vectors:
Consider the vector class:
class vector
{
private:
int rows ;
double *vec ;
public:
vector(void) { rows=0 ; vec=0; } // default constructor
vector(int rows) // constructor
{
vec = new double[rows] ;
}
~vector(void) {} ; // destructor
} ;
when i use the class in MAIN() like:
vector* A ;
A = new vector(15) ;
I get an error. It's giving a "null reference error" and saying that the object has not been instantiated..
I don't get what I'm doing wrong?
Thanks
KBL
