how to allot a big memory?

11-Nov-01 21:48

TCHAR szPath[MAX_PATH];
 
  SHGetSpecialFolderPath ( CSIDL_FAVORITES, szPath, MAX_PATH, FALSE );

This requires the Active Desktop shell. On 95 and NT 4, use SHGetSpecialFolderLocation() instead.

In my machine(win2000,mem 128)
when I use the sentence to allot memory,it show error in run!

unsigned char *pTemp = new unsigned char[600000];

but when I user
unsigned char *pTemp = new unsigned char[400000];
it is right in run!

why?
can you tell me how to allot a big memory ,like 1000000 char!
thanks in advance!

You shouldn't have any problems with allocating 600kb of memory. What kind of error are you getting?

Using comctl v6 manifest on XP

Michael Dunn11-Nov-01 18:19

11-Nov-01 18:19

I'm having a heckuva time with XP themes. I have two apps, one a shell extension DLL and one a standalone EXE, and neither one is getting themed properly on the release build of XP, but they work fine on beta 2 (which is all I have to test with). On both I've put an XML manifest in the resources, as described in MSDN. Dropping a .manifest file in the same directory as the binary has no effect.
I'm stumped... has anyone had this same problem (and more importantly, fixed it)?

Did you put InitCommonControls(), or something like that, in the standard initialization?

I did, and #defined ISOLATION_AWARE_ENABLED as well... although would InitCommonControls() have any effect in a shell extension? I'd think Explorer would do that itself. ah well... I'll double-check my code to make sure.

I went back and added InitCommonControls() before my calls to DoModal(), but the dialogs still don't get themed. Mad | :mad:

I'm just puzzled why it partially works on beta 2, because I must've been doing something right.
Ah well, can you think of anything else?

// Standard initialization
InitCommonControls();
// If you are not using these features and wish to reduce the size

I put it there I am using VC6 SP4 on Windows XP Home Edition.
Are you using MFC?
Is the manifest a type "24" resource?
(Yeah I know stupid questions but I had to ask)
Other than that I am pretty much stumped.

No MFC, it's all ATL and WTL. The manifest is type 24, with ID 2 (MANIFEST_RESOURCE_ID).
Thanks for the ideas, Matt. I guess XP users will have to go without the cuuuuuute round buttons. Wink | ;)

It's 1 for EXEs, 2 for DLLs. Smile | :)

Hmm... Try 1 once. Other than that I am lost. You can just tell the users that the new theme is evil.

1/ SHBrowseForFolder

2/ check Want Return/Multiline for the edit box

thanks for that, got the browsing working pretty quick, but i was asking how to make it do something when the user hits enter in the CEdit, not so its multiline, sorry for the confusion, again thanks in advance Smile | :)

Then you still want to catch the return key, you want to override OnChange for the edit and check if the return key is down.

Using MFC with a Console Application

13-Nov-01 0:14

oh i get ya, but after looking through the msdn i'm still having trouble checking weather they press enter or not, any good articles here on cp or other around, done a quick search and couldn't find any,

thanks.

Hi All,

I've been splitting one of my MFC apps into two parts recently (Service & Visual). I've written the Service as a NT Console type application but wanted to use such things as CStrings & also the COleDispatch object.

To do this I've included afxwin.h, afxext.h, and afxdisp.h.

My question is: is there any reason I shouldn't be doing this or should I be looking at using something such as the CNTService class on this site? (Hopefully there is no reason as otherwise I'll have to rewrite my code OMG | :OMG:

)

Richard.

If you are using Visual C++ 6.0, you can create a console application that supports MFC. I would create a test application and see the differences between yours and the new.

Hope this helps.

Finding the TEMP directory?

This is a followup to a previous question, but how do I use the shell namespace functions to find out the currently mapped temp directory? I can't seem to find it in MSDN anywhere...

Thanks,
