I need to look up "real names" for GUID's (Interface name, CoClass name, TypeLib etc.)
I know that the info is available in the registry, and that VC6 debugger does it nicely.

is there anything I can reuse? Or do I have to venture on my own?

it's pretty easy, but don't know any API for that

you have to only open registry at the right place.
If you look to HKCR\CLSID\
you'll see a bunch of GUIDs in text form for objects, you have to open registry key
HKCR\CLSID\{GUID} and get the default value to retrieve the name of the object

for interfaces the same
HKCR\Interface\{IID}

suprisingly for Typelibs it's little different
HKCR\TypeLib\{LIBID}\1.0 (or another version number)

you can check it directly in regedit.

Hope it helps

Adding your name as author to an exe's properties

When you right click an exe file you get the company's name, I'm wondering how you create this information? I would assume there's a setting in VC++ and studio.NET that compiles this information into the file but I'm not sure where to find this setting.

Obseve everything, remember more...

In resources tab, click Insert > Version and fill out the version info for your app. That'll get compiled in the exe and Windows will be able to associate your exe file with a company etc. when viewing properties or in small text beneath the icon in explorer Smile | :)

Hi,

take a look to your ResourceView in VC++.
You will find the resources of your project and also a version-resource (VS_VERSION_INFO). If not, add a version-info to your project.

Regards
Frank

I have an application on a CD. I want to copy protect it(do not want the user to copy it form the disk)Is there any secure software available.

All sugestions are welcome and its urgent!!

Thanx in advance.

There's nothing available, that's really working. Only thing which works for 100% is not to giving the CD away, sorry.

Problem is, that if the operating system can read it (as it must to access it) someone else can do it as well.

You can do some sort of protection to check if the right CD used, but if your software is good, then next day or after next day will be some cracks available to overcome that problem.

Only solution I found working is support. You'll support only registered and paying Wink | ;-)

customers, giving them a feeling that it's better to buy it than just copy it.

Check out www.securom.com, it'll give you a little while at least before the hackers get in. Doubt its free though. Personally I prefer silent copy protection methods, such as those in Championship Manager 4 and Unreal Tournament, where (in CM4) if a copied disk is inserted it allows you to play the game, but every game you play is fixed so you lose. This way will at least keep those people who buy one copy and share it amongst friends at bay from researching a hack because they aren't aware its the copy protection doing its job Smile | :)

Greetings All,
Is there an API call to find a string within another ?
How about with wildcard Chars
How about with wildcard char[] (i.e a wildcard that represents any number of chars) ?
Cheers

API no, library yes, _tcsstr, strstr.
The wildcard stuff is a different issue. One way to do this is with regexp, although something that handles only ? and * is simpler.

try this function. It should work

int Compare(const char* mask, const char* s)
{
const char* cp=0;
const char* mp=0;

for (; *s&&*mask!='*'; mask++,s++)
if (*mask!=*s&&*mask!='?') return 0;
for (;;)
{
if (!*s)
{
while (*mask=='*')
mask++;
return !*mask;
}
if (*mask=='*')
{
if (!*++mask)
return 1;
mp=mask;
cp=s+1;
continue;
}
if (*mask==*s||*mask=='?')
{
mask++, s++;
continue;
}
mask=mp;
s=cp++;
}
}

There are commercially available generic USB drivers that can adjust to virtually any protocol, and support all relevant OS versions.

I am not aware of a free / cheap solution, or one provided with the OS.

reverse_iterator

I have an STL list, and I want to move on it from back to front. I am trying to use the reverse_iterator, but I am getting a compilation error. Here is my code:

typedef std::list<RECT> RectList;
RectList myList;	// The list is created and initialised elsewhere
 
for ( RectList::reverse_iterator ri = myList.rbegin();
		ri != RectList.rend(); ++ri )
{
	*ri = *(ri + 1);
}

I get the following errors in the last line:

error C2784: 'class std::reverse_iterator<_RI,_Ty,_Rt,_Pt,_D> __cdecl std::operator +(_D,const class std::reverse_iterator<_RI,_Ty,_Rt,_Pt,_D> &)' : could not deduce template argument for '' from 'class std::reverse_bidirectional_iterator<class std::list<struct tagRECT,class std::allocator<struct tagRECT> >::iterator,struct tagRECT,struct tagRECT &,struct tagRECT *,int>'

error C2676: binary '+' : 'class std::reverse_bidirectional_iterator<class std::list<struct tagRECT,class std::allocator<struct tagRECT> >::iterator,struct tagRECT,struct tagRECT &,struct tagRECT *,int>' does not define this operator or a conversion to a type acceptable to the predefined operator

You can only increment or decrement iterators, not add a numeric offset to them.

But he can dereference them and use operators on the referenced object.
Provided that the operators are defined for the object.
Was it that what he tried: *r+1 ?

His code is doing this:

<br />
*ri = *(ri + 1);<br />

i.e. he is trying to add one to the iterator, *then* dereferencing it.

Thanks for your reply. But why can't I add to the iterator? According to MSDN[^], the reverse iterator contains operator+. What I don't know is what this operator takes as input.

Anyway, I changed my code to this and it compiled:

for ( RectList::reverse_iterator ri = myList.rbegin(), ri2 = myList.rbegin();
		ri2 != myList.rend(); ++ri )
	*ri = *(++ri2);

Thank you for your help.

You get an error here, because you can not use '+' with an iterator.
If you want to assign the value of the next object to the current one, I would do:

{
  RectList::reverse_iterator next = ri++;
  *ri = *next;
}

If you want to access an iterator that is more than one step away, you can use std::advance() to step the iterator many steps.

If you intended to add a value to the value referenced by ri, you need to write:

*ri = *ri + value;

Your code does the opposite of what I wanted. I would change it to:

   RectList::reverse_iterator next = ri;
   *ri = *(++next);
}

Thanks anyway.

Control on a ScrollView that doesn't scroll. How to achieve this?

steven1115-Sep-03 19:24

15-Sep-03 19:24

Hi,
how can I achieve this behaviour? I have an SDI-Application with CScrollView-derived View-class and I want to show the user a CStatic-derived control which shows a statistic. But this statistic should be permanent at the same place even if the user scrolls.
I prepared the control to be a Child from my CMainframe-class but then it gets overdrawn by the View. Then I wrote blah->Invalidate() in the OnDraw of the View to get the control to be drawn AFTER the View. But now I have the problem that there are "visual copies" (silly expression but I hope you understand what I mean...) of the control when I scroll...
has anybody an idea how to solve this problem?
(sorry for my English, I'm German...)
