VC++ 6.0 verson. yes you are right about the copy constructor. I (the vector has the problem) have a problem with the CString(s) that make up CDriver data. This is my first project using the STL. I'm tring to do everything by the book "C++ from the Gound Up", H. Schildt.
In debug mode I check the loading of the CStrings and sometimes it will load correct (itself) and other times it only loads partially. The vector will only load oned CString using the push_back() method; even when I see in debug that the CString IS LOADED but the vector ignores the passing of the CSting the second time.
Any ideas?

Does this fragment work OK?
std::vector<CString> temp;
temp.push_back(CString("ABC\n"));
temp.push_back(CString("DEF\n"));
temp.push_back(CString("GHI\n"));
std::vector<CString>::iterator it;
for(it = temp.begin(); it != temp.end(); ++it)
{
ATLTRACE((LPCTSTR)(*it));
}
Should print ABC,DEF,GHI on successive lines....

Yes and no. I don't know what "ATLTRACE()" is; but if I change it to:
std::vector<CString> temp;
temp.push_back(CString("ABC\n"));
temp.push_back(CString("DEF\n"));
temp.push_back(CString("GHI\n"));
std::vector<CString>::iterator it;
for(it = temp.begin(); it != temp.end(); ++it)
{
cout << ((LPCTSTR)(*it));
}
This works!!!

Then the vector<CString> stuff is fine.
ATLTRACE, by the way, is like cerr << stuff but outputs to a debug window. It assumes you're using ATL, which generally, if you're using ATL explicitly, or WTL, you will be doing, and it also assumes you're running a debug version, with something like VS.NET or DebugWin catching the output.

If ur dll is an automation compliant IDispatch implimented dll u can do the following:
Press Ctrl+W, goto class wizard --->Automation tab. Then click "Add Class" button. It will popup a file browse dialog. select the dll from there. Wizard will generate a class for ur COM CoClass.
1) Create an object fo that class class.
2) Call CreateDispatch method on that by passing the PROGID of ur class.
use the class object as a c++ class to make calls to its methods.

I have no problem compiling "normal" Win32 apps in either Release mode or Debug mode. However, whenever I compile a WTL app it compiles successfully in Release mode, but when I try to compile it in WTL mode I get the following two errors at link time:
Demo.obj : error LNK2001: unresolved external symbol "void __cdecl operator delete[](void *)" (??_V@YAXPAX@Z)
Demo.obj : error LNK2001: unresolved external symbol "void * __cdecl operator new[](unsigned int)" (??_U@YAPAXI@Z)
This happens with every WTL project I try.
What's wrong ?

Hello!
I am new in ATL programming. I am trying to write a program where I need to pass a class pointer to one of the method inside the library. Class is written by me and the purpose is to store some data in a linked list. I am always getting next error:
c:\documents and settings\...\dblib.h(30): error MIDL2025 : syntax error : expecting a type specification near "class"
Some code:
this is an IDL file:
[id(3),helpstring("method LoadOptions")] HRESULT LoadOptions([out] class OptionList *op);
this file/line is generated by the compiler.
that how it looks in .h file:
[id(3), helpstring("method LoadOptions")] HRESULT LoadOptions([out] OptionList *op);
(Error in this line)
I have no idea how to correct the error. As I understood, the problem that I can pass only simple data type to the ATL method. Class is not so simple... 
I read next article:
http://www.codeproject.com/atl/udtdemo.asp
Did not helped me a lot... I can not find any other information.
Any help appreciated.
Thank you!

Give the method definition as follows -
[id(3),helpstring("method LoadOptions")] HRESULT LoadOptions([out] DWORD *op);
Before passing in the class pointer, typecast it to DWORD* and inside the method typecast it back to the class pointer.

Waiting fo the reply.

Hi
Is ATL window programming widely used? Or MFC is still the first choice in window programming, then followed by the new WTL?
thx
|
|

|

I would be shocked if there is anything but a very small group of people doing large scale application development with just ATL. Application with WTL is much more common, but I would still say rare when compared to MFC.

I'm going to patent thought. I have yet to see any prior art.

In the UK we do occasionally see job ads which specify experience with WTL. In fact I once had an application rejected because I said I didn't know WTL. As I could satisfy 10 out of the 11 requirements I didn't think WTL would be taken as a deciding factor. But then this was at the bottom of the downturn when employers were even fussier than they are now.

Hello...
I like to support custom text printing in my application (without an edit control)...
The wtl examples that i found at codeproject only support text printing with edit controls...
I implemented the CPrintJobInfo class but unfortunely when it draw the text to the dc (in the PrintPage method) it only print the first drawing operation...
For example .:
bool CMainFrame::PrintPage(UINT nPage, HDC hDC)
{
CDCHandle dc = hDC;
CString text = _T("A Test");
dc.TextOut(0,0,text,text.GetLength()); // This text is only visible on page
dc.TextOut(0,20,text,text.GetLength());
dc.TextOut(0,40,text,text.GetLength());
return true;
}
I hope anybody can help me  ...

Ehmmm... I have found the bug or better my own mistake... 
I forget the different resolutions between the screen and printer dc...
The distance between the 3 strings was to small to see them completly... 
For example.:
dc.TextOut(0,0,text,text.GetLength());
dc.TextOut(0,400,text,text.GetLength());
dc.TextOut(0,800,text,text.GetLength());
woks...

Hi,
sorry if this has been asked before, but i read the two articles on COM Addins for Outlook 2000/2003:
http://www.codeproject.com/com/outlookaddin.asp[^]
http://www.codeproject.com/atl/outlook2k3addin.asp[^]
and have to implement an Addin for Outlook 2003.
Seemingly, i have not been able to create the Addin properly, as i experienced the following problem:
When it comes to importing the Office & Outlook typelibraries i face the problem of not knowing which DLLs are appropriate.
You know, the articles use Outlook 2000 DLLs, even the one on Outlook 2003...
<br />
#import "C:\Program Files\Microsoft Office\Office\mso9.dll" \<br />
rename_namespace("Office") named_guids <br />
using namespace Office;<br />
<br />
#import "C:\Program Files\Microsoft Office\Office\MSOUTL9.olb" <br />
rename_namespace("Outlook"), raw_interfaces_only, named_guids <br />
using namespace Outlook;<br />
I manage to find the second file, the appropriate *.olb file, but not the also needed MSOXXX.dll file of my Office installation, as the dll is renamed in Office 2003.
I tried several DLLs in the directory, but none has worked as i get a failure when i build the project (in MS Visual C++ 6.0).
Any ideas?
Regards,
Harry

Use the following files
#import "E:\\Program Files\\Common Files\\Microsoft Shared\\OFFICE11\\mso.dll" \
rename_namespace("Office") named_guids
using namespace Office;
#import "E:\\Program Files\\Microsoft Office\\OFFICE11\\msoutl.olb" \
rename_namespace("Outlook"), raw_interfaces_only, named_guids
using namespace Outlook;

I have build an activeX controller in ATL VC++ that uses a window and shows camera captured frames, it works well in VisualC environment.
In Visual Basic 6, however, When I tried to integrate the control into a project, it was loaded ok but when I tried to save or run the project, I got a system Error
&H80004005 (-2147467259).
When I tried the same under .net environment, this problem didn't appear.
DO you have any idea what can be the problem or how can I debug it ?
Thanks
