Few weeks ago, I' ve found a very interesting fractal program ( trial version can be downloaded from http://www.ultrafractal.com/uf305.exe ). And I was wondering if somebody could tell me, how to insert a similar Dialog bar ??

boottime screen output (eg. checkdisk)

I've been reading docs for months now, and I still don't have a clue how to do it or where to get indeep information. Confused | :confused:

I'm looking for a guide howto output messages/text to screen at XP boottime for a win32 console application I wrote. The goal is to tell the user about the progress/status of the tool. I'm talking about the console-like blueisch screen that checkdisk and some 3th party defraggers use when doing stuff at boottime. Eek! | :eek:

Furthermore - since I'm guessing it'll have to be a service application - where do I start it? (from the registry, as a regular autostarting service or what?)

Anyone who can help me on this quest of knowledge could have a good chance of becomming a godlike person in my eyes Wink | ;)

... in other words: I would be more than thankfull for any info I get here! Rose | [Rose]

Here's a start: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager, string value BootExecute holds the command line to run.

Thank's, but I allready tried that... it didn't do a thing, as if the app was just skipped or ignored. Guess the real question is: how do I "talk" (get a screen handle) to that blue screen?

Does this make sense?

Turtle Hand23-Dec-04 5:37

I'm trying to track down a memory leak. It was suggested that fxA() leaks. So I set a breakpoint before execution enters that function and after. When execution stops at the 1st breakpoint, I check memory for the process in Task Manager. F10, and when execution stops at the 2nd breakpoint, I again check memory. Memory is the same! This tells me that fxA() is NOT leaking.

Per Microsoft suppport, fxA() is the 4th biggest leak in the application. Are they wrong, or is this method of checking if a function leaks flawed?

This method of checking leaks is flawed. Memory is allocated in blocks of 4 or 8K. You may have allocated memory that is small enough that an entire new block was not required so you would see no apparent difference in the process' memory usage.

This makes sense, a CStringArray and CArray are passed in by reference and filled in fxA(). This means fxA() uses memory and doesn't release it upon exit.

That doesn't make this function leak memory though, because it's the calling function's responsibility to release the memory of the CStringArray and CArray when those objects are out of scope.

how was fxA() suggested that it leaked ?

does fxA() allocate memory ( with new or malloc ) ?

is it the task of fxA() to also free that allocated memory ? or is it passed on to the caller or somebody else ?

if you use things like _malloc_dbg or DEBUG_NEW in visual studio, you will be able to really see where the leaked memory is really allocated.

compiler versions

Hi, sorry if this is a really dump question...
How do i check what version the compiler is?
I want to destinguish between Visual Studio .net 2002 and Visual Studio .net 2003 at compile time...
e.g.

<br />
#ifdef VS_NET_2002<br />
  do this<br />
#elif VS_NET_2003<br />
  do something slightly different<br />
#else<br />
  #error compiler not supported<br />
#endif  <br />

Thanks for any help!

Test the _MSC_VER symbol. For VC 7 it's 1300, for VC 7.1 it's 1310.

I don't know of a full list (should be findable with Google) but the value always matches the compiler version (version 1 being the first C compiler). So in VC 6, with compiler version 12.00, _MSC_VER is 1200.

Environment Variables - Scope

23-Dec-04 4:29

I have just interfaced with my first Corba Server, but the only way I can run my client application is via a batch file as lots of Environment variables need to be set up and they are setup via a batch file whitch then run my program.

So for debugging you lose the Visual Studio IDE.

Are they any way that my program can call this batch file or implement what the batch file does (adds a path to the path variable path and defines these environment variables)

I know I could define all these variable into the system (via My Computer, but they are about 50)

ANy comments please,

Merry Christas,

Can you not "attach to the process" and debug that way?

In .net 2003 -- go to the debug menu, select "Processes..." and hit the "Attach..." button.

CListView - limited number of items

Hi Gurus,

My CListView-based control doesn't display items more than 200. Why? I've got no error while calling CListCtrl::InsertItem().

Moreover, CListCtrl-based control in the same application but on different dialog box works without above problem.

I can't realize why. Please, help.

Sincerely Yours,
RadioShark

Problem with convertion unicode string to ansi string(CString)

Hi All,
I am using .Net 2002 environment in windows 2000 OS. I am try to convert unicode(Japanese) string to CString. I can convert the unicode string to ansi string(CString) when i set the locale(japanese) in regional options. That was showed like come ascii chars(,"&#êÜ&#). If i set the locale to english, then the ascii chars showed as ??? marks. But the need is the unicode convert into some ascii chars like from japanse locale. I tried to set the locale using setlocale() method. But there is no effect. I wrote the code is
setlocale(0,"Japanese");
The default locale is not set. I want to set the default locale dynamically. If anyone have the solution about this problem, please let me know.

Hi DavidCrow,
The setlocale returns Japanese_Japan.932, that means its taken Japanese locale. I want to remind you that if set the default locale then its working fine(Japanese locale set).

Thanks and Regards,

How to create a wrapper for CLucene in MFC

23-Dec-04 0:59

hello,
when i started making a wrapper for clucene in MFC, i made the frontend of searching files and directory using the system namespace.
using namespace System;
using namespace System::Collections;
using namespace System::IO;

but then when passing the "path" arguments to functions defined in clucene there is a mismatch of type.path in clucene is of type char[] and the directory specified in my frontend is of type System::String * __gc.

is there nething that i am doing in a wrong manner.or is there some other way to create a wrapper for clucene in MFC.

i may be wrong in my "coding" as i have started this coding buisness very recently.please correct me.ne help will be deeply appreciated..
thanking you all...

Extern Message on my dialog, what's the event?

Lvca23-Dec-04 0:47

Hi,
On my application ( eVc++ 4.0 - PocketPC2003 ) I use a Dialog that cuts the task bar and fits the screen the code to do that is:

void FitIt(HWND Form)
{
CWnd* TaskBarWnd = CWnd::FindWindow(_T("HHTaskBar"), _T(""));
if (TaskBarWnd) TaskBarWnd->ShowWindow(SW_HIDE);
SHFullScreen(Form, SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON );
#define MENU_HEIGHT 26
CRect rect;
GetWindowRect(Form,&rect);
rect.top -= MENU_HEIGHT;
MoveWindow(Form,rect.left, rect.top,rect.Width(), rect.Height(), TRUE);
}
(I call this function in the end of the OnInitDialog())

The problem is: when an extern Message appears(such as the one that advises me that I'm connecting or disconnecting to the pc) , when this Message disappears the Dialog is redrawn
"over" the other, but starting from the point under the first
taskbar, with the result that all the form seems to be moved down and I get double "mytaskbar".
I'm asking: what event exactly happens when an extern Message comes over my dialog? where can I write the code to build again my dialog when a Message appears?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
