You can always use OnScroll and call the Invalidate and UpdateWindow to force the redraw of the screen.

Hi All,
Im using a application in which im loading the Spin Control at run time. This spin control will
change its value on every click of the up/down button. But number of times it can change its value
is 65536 which is defined in CSpinControl which is defined in the CSpinButtonCtrl class(SetRange32
function). I want to increase this range of spin control beyond 65536. If anyone kno about this plz
let me kno.
I tried to increase the no of elements in the list, but its giving me the performance problem.
The speed of the spin control scrolling is getting slowed down. If anyone can help me in this regard,
plz reply me ASAP.

Looking at UDM_SETRANGE32, you can set the min and max to 32 bit values which are a lot larger than 65536.
If you are talking about how big a jump it does when you click on a button, look at the UDM_SETACCEL message.
Worst come to the worst - shrink the values, and multiply them within your own software. There's no reason why you can't do...
UINT nMyValue = 100 * m_UDCtrl.GetPos ();

Hi Iain,
Can u be more elaborate on hw to set max and min to 32 bit values. M not getting as UDM_SETRANGE32 is system #defined.....

Errr...
What's wrong with:
m_MySpinner.SetRange32 (0, 1234556);
int nLower, nUpper;
m_MySpinner.GetRange32 (nLower, nUpper);
ASSERT(nUpper == 1234556);

I have already tried this...its not working.
Is this code working properly in ur case??

Hi all,
I want to make a self extractor application for my setup code. But i am not getting the path as where to start from.
Can anybody please tell me how to start with it...
Thanks in advance

If you want to make JUST a self extractor... why don't you use the Winzip self extractor tool? Is the easiest one I know, wizard steps, just make a folder with all the things you want to have in the places you want to have them and pack it up. Unpacking will use the path from where you create the selfextractor if you don't give any other command.

For building setups, I use NSIS.
You can not possibly get better than those (free!) tools without just recreating them.
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Use IExpress. It is easy and comes with each and every Windows. and you don't need to download anything else.
just time iexpress in Run menu and it will appear.
It also provide the facility that Run the selected file on starup.

hello,everybody!
Now I want to generate a wmv file through wm asf writer,I got IWMHeaderInfo from WM Asf Writer filter,then revoked SetAttribute to set aspect ratio like follow:
DWORD AspectX;<br />
DWORD AspectY;<br />
if ( m_settings.GetAspectRatio() == IOutputSettings::Aspect_16_9 )<br />
{<br />
AspectX = 16;<br />
AspectY = 9;<br />
}<br />
else<br />
{<br />
AspectX = 4;<br />
AspectY = 3;<br />
}<br />
<br />
hr = pWi->SetAttribute(0,L"AspectRatioX",WMT_TYPE_DWORD,(BYTE*)&AspectX,sizeof(DWORD));<br />
hr = pWi->SetAttribute(0,L"AspectRatioY",WMT_TYPE_DWORD,(BYTE*)&AspectY,sizeof(DWORD));
But at last it did't work,when I playbacked my wmv file,it still was rendered with 16:9.
So I change another method,I got IWMStreamConfig2 and revoked the AddDataUnitExtension like this:
DWORD dwValue = 0x0193;<br />
hr = pConfig2->AddDataUnitExtension(WM_SampleExtensionGUID_PixelAspectRatio,2,(BYTE*)&dwValue,sizeof(DWORD));
At last,it also didn't work.
I am almost crazy,does anybody know it?
Thank you very much!

Hello everyone,
I have a number of strings in an array,
"FILE1", "FILE2", "FILE3", ... , "FILEN"
I want to add the common prefix to all the string, like
(for example, the common prefix is "FOO")
"FOOFILE1", "FOOFILE2", "FOOFILE3", ... , "FOOFILEN".
Are there any smarter ways to use a macro to define all of them altogether?
thanks in advance,
George

Never heard about itarations (i.e. why do you need macros, do you want strings initialised at compile-time?)?

Thanks CPallini,
Using other techniques are also ok if it could save my typing time,
My situation is, I have some legacy code, which is an array -- very long, and all the file names are constant values. And to save my time of typing, I want to find some smarter ways to add prefix to all file names in the aray.
Any good ideas?
regards,
George

What kind of string you are dealing with (e.g. CString or whatever...)?
Maybe posting a little code snippet will help.

A TCHAR array. Any ideas?

George

I don't know details of the code you're dealing with (since you did post no snippet) hence I can't help: maybe there are smart ways to do what you need, but, unfortunately  I'm not a fortune teller.

Thanks CPallini,
Here is some pseudo code, it is appreciated if you could share some ideas. Let me know if you need any further information.
<br />
#define PREFIX "FOO"<br />
<br />
int main()<br />
{<br />
TCHAR array_before [5][256] = {_T("FILE1"), _T("FILE2"), _T("FILE3"), _T("FILE4"), _T("FILE5")};<br />
<br />
<br />
<br />
}<br />
<br />
<br />
regards,<br />

The best way was already suggested by toxcct [^].
BTW why don't you make a search-and-replace with your current editor?
On the other hand, since strings obey a regular pattern, you have the option to keep code compact, building such pattern at runtime.

Hi CPallini,
His (her) code does not compile. How to do a search and replace? I want to add prefix... nothing to replace.

George

IMPOSSIBLE.

With search-and-replace tool of your favourite IDE (e.g. Visual Studio) or editor (e.g. notepad++).
George_George wrote: I want to add prefix... nothing to replace.
Yeah, but with the support of (a bit of) imagination:
_T("FILEX") becomes _T("FOOFILEX")
if you search for _T("FILE and replace it with _T("FOOFILE

Hi CPallini,
Could you try the code please? I am using Visual Studio 2005. The code can not compile. If there is any programming error in the code, please feel free to let me know.
<br />
#define PREFIX(x) _T("FOO##x");<br />
<br />
<br />
int main()<br />
{<br />
<br />
const TCHAR* SecondArray [2] = {PREFIX(_T("FILE1")), PREFIX(_T("FILE2"))};<br />
<br />
TCHAR* p = NULL;<br />
p = SecondArray [0];<br />
p = SecondArray [1];<br />
<br />
<br />
return 0;<br />
}<br />

Anyway, the following one compiles:
#define PREFIX(x) _T("FOO") _T(#x)
int main()
{
const TCHAR* SecondArray [2] = {PREFIX(FILE1), PREFIX(FILE2)};
const TCHAR* p = NULL;
p = SecondArray [0];
p = SecondArray [1];
}
Be careful: copy exactly as it stands

Sure? I mean, nesting macros? Is that version-dependent?
No, it is not:
"...the formal parameter is immediately replaced by the unexpanded actual argument. Macro expansion is not performed on the argument prior to replacement."
Looks like your macro will expand to nonsense...;P
_T("FOO") _T(FILE1)
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Hi jhwurmbach,
I do not quite understand your points. The code works in my Visual Studio 2005 environment. Could you show some pseudo code to express your ideas please?
