I have been trying to build my first DLL but keep getting the following error and have no idea what it means. The Help not very useful either.

Have you verified that no references to this file exist in the project's .dsp file?

One of the library files seems to have referenced this file. I have removed it as I dont seem to ned it at present.
However I now get the error when the DLL is loaded:-
no 'initialize' entry found in the TEST_DLL
I have been trying to write a DLL for the CSL scripting

The documentation is a bit light for this sharewear product.

I would welcome some help on this problem (Win32, MFC)...
I wish to ensure some text processing code always executes in the English locale. I have bracketed the code with setlocale() calls as follows:
:
// Native locale code
:
_tsetlocale(LC_ALL, _T("English"));
:
// text processing code, sprintf()s etc.
:
_tsetlocale(LC_ALL, _T("C"));
:
// Native locale code
:
Debugging through this code always shows the setlocale() calls succeeding (returning the selected locale string). However, the first time through, sprintf() floats are incorrectly output in the Native locale format, while the subsequent iterations through this code correctly produce English formatted numbers.
The text processing code exists in a static library written in plain C, while the surrounding code shown above is a C++ DLL linking to the static library.
Any ideas what might be causing this problem and how to solve it?

Look up MSDN on setlocale - you will need to pass in something other than "Enlgish". On Windows, it is usually something screwy like Windows_English_CP1252 or whatever. I can never remember the exact strings.
You can also call setlocale with the empty string as a locale, and it will load whatever locale is your system default.

Hi !
I've a C++ question regarding the copy constructor.
Here is my example :
Let's say I've a class which contains a list of pointer on Polygons, called PolygonList.
In the copy constructor of my class PolygonList, I want to fully duplicate the polygons which are stored, so that each PolygonList classes have their own polygon list.
class PolygonList
{
public:
...
std::list< Polygon*> m_PolygonList;
...
};
The problem is that the Polygon class is a base class :
class Polygon
{
...
};
class Rectangle : public Polygon
{
...
};
class Triangle : public Polygon
{
...
};
etc...
In the copy constructor of the class PolygonList, how can I make sure to instanciate a new object of the good derived class, as I only have pointers on the base class and don't know (and don't want to know) about which dervied class of Polygon exists ?
I hope I made myself clear and that you'll be able to help me !
Thanks !

I'm writing an application that read data from a Access 2000 database using ADO.
When I read a string field and I save it into a _variant_t variable I can see the right value, but that I want to pass this value to a CString variable and then I get always the first letter of the original value.
I have write:
<br />
CStrin Data;<br />
<br />
Data = (char*)(_bstr_t)Rs->GetFields()->GetItem("string_field")->value;<br />
<br />
When I debug the program I can see that Data holds only the first character of the string.
What I doing wrong?.
Thank you.

How are you looking at the data? In the Watch window, you might need to use the su symbol. Also, look at Data.m_pchData[1], Data.m_pchData[2], Data.m_pchData[3], etc to verify that the CString object contains.

Hi!
Yes I'm looking in the Watch window and I expand the Data, (Data is the CString variable) three, (clicking in the + simbol) and I only see m_pchData, (without subindex and there are not others members), with the value in Ascii of the first character in the string, example: I have de the string "188510015B" and I get "1", so in Data._pchData I see 49.
What is the su symbol?.
Thank you.

Like I indicated, you need to look at Data._pchData[0], Data._pchData[1], Data._pchData[2], Data._pchData[3], etc.

It's for viewing Unicode text. By default, the s symbol is used.

Hi All
I am using CHtmlView to view some static HTML pages. The problem is these pages are not on the local disk, ie we download these pages from our central server into a Temp Location on the local machine, but obviously any resources will also exists in the central storage. So I was hoping to somehow trap the call to get the resource ie http://www.website.co.uk/image.gif or as it is more likely to be MYTAG:///Pictures/image.gif to route to my own download function and update the tag, just like IE does with TempInternet Files.
We are already intercepting hyperlink clicks using the OnBeforeNavigate2 method.
I may be using the wrong Control.
Cheers
Jay.

Hi,
I have a server app that uses CreateNamedPipe using a NULL DACL so that everyone has permission to read/write to it.
I then have a client that uses CreateFile to read and write to the pipe. In XP this works on remote machines no problem, the server can be running on one machine and the client on another and the CreateFile returns a valid handle.
On 98 CreateFile returns access denied, which eludes me because the pipe is created with a NULL DACL.
Can anybody shed some light on the issue.
Thanks

Hi,
I did not know about the existence of MSXML. Is it a seperate download?

Why, Xerces[^] of course! Fast, free and open source! And it leaves MSXML in in the dust.

In my tree list when I right-click on my item it is not selected. I have to left click first which selects it. Then I must right-click on it to get the right item. How must right clicking select an item as though it is left clicking?

Hi,
I need to do some calculations but firstly, i need to extract values from the database and store it inside the array.
double para3[12] = {90.1, 75.2, 60.3, 91.2, 74.5, 61.2, 89.9, 74.8, 59.8, 91.4, 76.2, 60.6};
The above is method i use is hardcoding the values that i need inside the array but because i might need to add on more values to it, i can easily retrieve from the database instead of hard-coding.
Hope u can help me.. Thanks a million

Read up on the CDatabase and CRecordset classes. They allow for easy access to many data sources, including, but not limited to, databases.
