Damn - I hate not being able to crush a bug

I'm having the same problem. Are you inheriting from CObject and passing an instance to your View(s) via UpdateAllViews( , , instance )?
|
|
|
|
|
I have derived from the interface(IPimSrcContactNew),but the system did not invoke this API(IPimSrcContactNew::Create)?
Please help me. Thanks.

You need to do more than just inherit from it - it has to be a proper COM object.

Could you tell me in detail. thanks.

Not really - there's more to COM than I can tell you - you're going to have to learn about the technology underpinning your task.
Look for some COM/ATL tutorials like this one[^].

list<int> l1,l2;
...
find(l1.begin(), l2.end(), 1)</int>
This code compiles, so I think it is better to use following symantic:
find(l1, IndexBegin, count, 1);
It is more consistent, isn't it?

Iterators are a great way to traverse a list.
This makes the find algorithm to be used with any sort of container that implements iterators.
This way STL is able to have one single find algorithm that works with several different containers.

No. Who says you have to have a container? Who says you have identifiable indices and counts? What about when you want to iterate from end to beginning of a container rather than beginning to end?
Using iterators allows you to do some very neat things with iterator adaptors[^] and still be able to use standard algorithms.

Itearators are (roughly speaking) a generalization of indexes, just like, for instance, a vector is a generalization of a standard array. If you find useful vectors then, one day, you'll probably find useful iterators too.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

While navigating (with the wtl 8 tabbed browser sample) I often get script
errors on different pages and the scripts are not executed (the same problem
does not appear in standard internet explorer)
Tryed this solution:
http://kbalertz.com/261003/Handle-Script-Errors-WebBrowser-Control.aspx
but the Exec method of IOLECommand interface seems to get never executed
(note that Disable Script Debugging option is set as required)
also tryed this other solution:
http://support.microsoft.com/kb/317024
that seems to disable the errors in very few cases but the script are never executed.
Hope someone knows the point.
Thanks as usual.

I program an appwizard for VC6 recently,and want to create a project( using the appwizard) which has the follwoing name of a project's configuations,for example,
project's configuations:
default: new:
win32 Debug ===> Checked
win32 Release ===> Free
thanks!

I want to write an AppWizard for vc6,but I don't know how to get a project's active configuration.
(I am newbie in ATL)
could someone give me a hand?
void CWinDriverAppWiz::CustomizeProject(IBuildProject* pProject)
...
IApplication *pApp;
CComBSTR projname;
CComPtr<idispatch> iDisp=NULL;
...
pApp->get_ActiveConfiguration(&iDisp);
CComQIPtr<igenericproject,&iid_igenericproject> pActiveConf(iDisp);
iDisp=NULL;
pActiveConf->get_Name(&projname);
}

This worked for me with an add-in I wrote (note - m_piApplication, declared with type CComPtr<IApplication> is the IApplication pointer:
CComPtr<IDispatch> actCfgDisp;
if (FAILED(m_piApplication->get_ActiveConfiguration(&actCfgDisp)) || !actCfgDisp) return E_FAIL;
CComQIPtr<IConfiguration> activeConfiguration(actCfgDisp);
if (!activeConfiguration) return E_FAIL;
CComBSTR configurationName;
CString configuration;
if (SUCCEEDED(activeConfiguration->get_Name(&configurationName)))
{
}

I don't know how to initialize "m_piApplication"(IApplication* m_piApplication) by pProject(IBuildProject* pProject).
The problem puzzles me so long time1
|

You can't get m_piApplication from an IBuildProject.
Instead, you need to remember it from when VisualStudio calls the OnConnection method of your add-in object (that's the one that implements IDSAddIn).
I found this article[^] very useful when implementing my add-in.

Why the code not work?
I think it's expected that the output should be 4, but it asserts.
#include <iostream>
#include <vector>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
vector<int> v(10);
for (int i=0; i<10; ++i)
{
v[i] = i;
}
vector<int>::iterator it = v.begin();
it += 3;
vector<int>::iterator it0 = it + 1;
v.erase(it);
cout << *it0 <<endl;
cin.get();
return 0;
}

What is the assertion code, because i have tried your source and the result is: "5". And it should be "5" because v.erase(it); removes the element pointed to by it, so after this operation our fourth element is "5".
|
|
|
|
|
In the cout statement.
Compiled in VC9 SP1.

I have tried your code in VC6 and it works fine there, but in VC9 it asserts. So why this happens? The answer is "because of The STL implementation in VC8 and VC9". The new STL implementation includes additional checks, this line is from vector file, which comes with VC9
#if _HAS_ITERATOR_DEBUGGING
if (this->_Mycont == 0
|| _Myptr < ((_Myvec *)this->_Mycont)->_Myfirst
|| ((_Myvec *)this->_Mycont)->_Mylast <= _Myptr)
{
_DEBUG_ERROR("vector iterator not dereferencable");
_SCL_SECURE_OUT_OF_RANGE;
}
#else
After you call erase(it); the "it" iterator and all iterators pointing elements after the erased element will be invalidated, so you have to change your code if you don't want your iterators to become invalid. Here is one possible solution, it works fine on VC9:
...............
int main()
{
vector<int> v(10);
for (int i=0; i<10; ++i)
{
v[i] = i;
}
vector<int>::iterator it = v.begin();
it += 3;
it = v.erase(it);
vector<int>::iterator it0 = it + 1;
cout << *it0 <<endl;
cin.get();
return 0;
}
</int></int></int>
The result must be: 5.

The v.erase(it); line invalidates it0. vector iterators are invalidated when an element is added to or removed from a vector.

To re-iterate what I said - you program is erronous - it has no meaning under the semantics of C++ as defined by the C++ standard. Erasing a vector element with v.erase(it); means that you cannot rely on it0 to reference a sensible value.

OK, I realise I'm way behind the curve here, having spent my professional life maintaining MFC + FORTRAN apps, but now I'm trying to make use of some STL because it looks helpful.
Suppose I have the following:
struct Info
{
Point3D JunctionPt;
Point3D EndPtOne;
Point3D EndPtTwo;
double LengthOne;
double LengthTwo;
double DistToRef;
};
map<LONG, Info> m_PtsInfo;
I use a map because each JunctionPt is associated with a unique ID. Also, my loop for adding the info may come across each JunctionPt numerous times, thus I can use m_PtsInfo.count(ID) to see if I have added any of the info already.
Once my map is populated, what I really want is it sorted by DistToRef, but I'm not sure how best to achieve this. I didn't think using DistToRef as the key was a great idea...
Should I copy my Info from the <map> to a <set> with the appropriate comparison defined? Then sort the set? Or is there some other cunning STL trick I've missed to achieve what I want?
Cheers!

The purpose of map is that of a key/value pair.
The key is stored internally for fast access.
So if you want it sorted, there is no point in using a map.
You could probably use a pair.
