Your error message simply means that Windows can't find the program (getmac.exe), neither in "C:\Documents and Settings\Administrator" nor in the PATH.

So, where did you put that program?

Good morning.

What source code do you want?

The CP project http://www.codeproject.com/tools/MacIdChanger.asp[^]?

or the source code for http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/getmac-o.asp[^]

If its the CP project (MacIdChanger), why can't you download it?
If you want the source code for the getmac-program, I don't know if MS has published it or not. I suggest a Google search.

Kakan.

41 (you thought i'd say 42, so 41 is random).

... want another - 53.

Feel free to ask me whenever you want another one.
... or you can do what the other Chris said - use srand()/rand().

Or, you can do what most encryption engines do:
- accumulate a blob of random input data:
- current time
- current mouse position
- pixel color at mouse position
- process id, thread id
- mac address
- ...
- create a hash of the blob e.g. using SHA

SHA1 is 20 bytes long so you could use the resulting hash to get 20 random numbers by taking hash[i] % 100, where 0 < i < 20.

Hi there.
I would be greatful if someone have abit of sample code for me. I'm sure this isn't a difficult problem to someone that uses ADO/C++ on a regular basis.
I want to put a Checkbox column into a C++'s CDataGrid object (dialog based program). Do bear in mind, it's VC 6.0 and not .NET I'm using here.

Thanks..

Ctrl + Tab => next Page

WernerP5-Dec-05 10:15

5-Dec-05 10:15

Hi,

I have an MFC tab control which holds a couple of dialogs. On the first page there is a dialog which has a CListCtrl. I would like to implement

Ctrl + Tab => next page
Shift + Ctrl + Tab => prev page.

I thought this was simple - I would just override a WM_CHAR or WM_KEYDOWN or something similar. But the MFC handlers for these messages do not react to holding down/releasing Tab. They also don't give info, whether a combination of control keys like shift and ctrl are pressed together with tab.

Will I have to override PreTranslateMessage and set/unset a flag for the shift resp control keys when they are pressed/released? Or is there a more elegant solution?

Or is that kind of behavior already part of the tab control's standard implementation, and I just don't realize?

Thanks in advance
regards Werner

Property Page Tab titles

code dope5-Dec-05 9:22

I'm having real problems getting titles onto the tabs of a multi page Property Sheet.

I'm creating several pages dynamically in the Prop Sheet's constructor which are the names of all the ini files in a folder, as below:

However, the titles do not appear on the tabs and the only way I can get them on is to hard code them, instead of the line which assigns the title e.g pPage->m_psp.pszTitle = "Page Title";

Iv'e tried casting the strFound variable to (LPCTSTR) but stil no joy although this shouldn't be necessary.

Kind of defeats the idea of doing stuff dynamically!

Any help would be really appreciated - I've been round and round in circles on this!

Many thanks.

[I]if( GetCurrentDirectory( 256, (LPSTR) szCurrentDir ) != 0)
{
strFile.Format("%s%s", szCurrentDir, "\\system\\*.ini");
CFileFind finder;
BOOL bResult = finder.FindFile( strFile, 0 );

// get any ini file names...
while( bResult )
{
bResult = finder.FindNextFile();
// we don't want folders...
if( finder.IsDots( ) )
continue;

// get the file name...
CString strFound(finder.GetFileName());
// remove the extension...
strFound.Delete( strFound.GetLength()-4, 4);
// create a new property page...
CDiaryPage* pPage = new CDiaryPage( strFound );
// set its attributes...
pPage->m_psp.dwFlags = PSP_USECALLBACK | PSP_USETITLE | PSP_HASHELP;
// and give it its title...
[U]pPage->m_psp.pszTitle = strFound;[/U]

// then add it to the sheet...
AddPage( pPage );
}
finder.Close();
}[/I]

code dope.

What about PathRemoveExtension()?

I'm not sure about the actual problem you're having, however. What happens if you use CPropertyPage::Construct()?

From the property sheet class use

TCITEM TCItem = {0};
TCItem.mask = TCIF_TEXT;
TCItem.pszText = "Tab Text";
GetTabControl()->SetItem(PageIndex, &TCItem);

error C2228: left of '.ShowWindow' must have class/struct/union type

newbie53455-Dec-05 9:14

Hello -
This may be a very dumb question, but I've struggled with it a long time. I have two text boxes and I'm trying to control their visibility and enabled/disabled state, but no matter what I do I keep getting this or something like it with different commands:

VestExample error C2228: left of '.ShowWindow' must have class/struct/union type

Here is some of the code:

In header file (Dialogue Data):
int m_partnum; // text box
int m_degrees; // text box

In .cpp file:
DDX_Text(pDX, IDC_PARTNUM, m_partnum);
DDX_Text(pDX, IDC_DEGREES, m_degrees);

Lines causing error:
m_partnum.ShowWindow(SW_HIDE);
m_partnum.ShowWindow(SW_SHOW);
m_degrees.EnableWindow(true);

I have various buttons that respond just fine to these commands (defined in class wizard) and the text boxes are defined in the class wizard too. Thanks in advance for any help.

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