Woops, now i have another problem 
You see the thing i'm trying to compile is a DLL. A layered service provider to be exact (not that i think it matters much). But to compile it i always used the makefile, because when i made a workspace for it in VC it would compile, but it just wouldnt work right. So now i have my class with all the static functions and variables in the DLL project. But now when i try to compile with the makefile it gives me another linker error. An unresolved external for a public function from my class. I don't know much (or anything) about makefiles, just that they give options to the compiler and linker or something so i can't really understand why it doesnt work. My guess would be that when i compile it in VC it has other options set or something, so it will compile but the result will be a DLL that doesnt work right. Here is the makefile:
!include <win32.mak>
!IFNDEF NODEBUG
.cpp.obj:
$(cc) $(cdebug) $(cflags) $(cvarsdll) -DSTRICT -YX\
/D "DEBUG_TRACING"\
/D "TRACING" /Od /D "_DEBUG" $<
!else
.cpp.obj:
$(cc) $(cdebug) $(cflags) $(cvarsdll) -DSTRICT -YX -DNODEBUG $<
!endif
CPP_FILES= dbuffmgr.cpp\
doverlap.cpp\
dasyncw.cpp\
dworker.cpp\
dcatalog.cpp\
dcatitem.cpp\
dllmain.cpp\
dprovide.cpp\
dsocket.cpp\
spi.cpp\
trace.cpp\
dthook.cpp
OBJS= $(CPP_FILES:.cpp=.obj)
all: lsp.dll inst_lsp.exe
lsp.dll: $(OBJS)
$(link) $(linkdebug) $(dlllflags) \
-map \
-export:WSPStartup \
-out:$*.dll $(OBJS) $(guilibsdll) ws2_32.lib
inst_lsp.obj: inst_lsp.cpp
$(cc) $(cdebug) $(cflags) $(cvars) inst_lsp.cpp
inst_lsp.exe: inst_lsp.obj
$(link) $(linkdebug) $(conlflags) -out:$*.exe inst_lsp.obj\
rpcrt4.lib $(conlibs) ws2_32.lib sporder.lib
clean:
-del *.obj
-del *.dll
-del *.pch
-del *.exp
-del lsp.lib
It creates two things basically, an .exe and a .dll. It also exports the WSPStartup function so windows can access it. But as i said i get an unresolved external linker error on the static public function of my class since i added my class.
P.S.: I try to call this function from some global function in the DLL like:
CMyStaticClass::MyFunction(someparameters);

hi,
i need a control to show a message near the system tray. It should be in win32 (no MFC please). My app runs in the system tray, and needs to show a message (like 'you've got mail').
please point me to any good source code. i cant find any.

Go check the MSDN section called 'Using ToolTip controls'. ToolTips are small messages displayed to the user. Their general use is to pop up when you hover the mouse over an icon. However, even the 'Click here to stay current with automatic updates' tooltip bound to the Windows Update System tray icon is just a standard tooltip, with some extra styles applied.
The article is a good place to start. Unfortunately I cannot provide you with a ready code.
Here is a link to it: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/tooltip/usingtooltips.asp[^].

I don't understand why "copyLine(ifstream& fins, ofstream& fout)"?
Why copyLine function has to be passed by reference. The first
code is presented in textbook as an example, however, it doesn't
explain why copyLine must pass by reference. The second is rewritten
by me in attempting to use another apporach.(the apporach that does
not need to pass by reference) But the second one got an unresolved
fatal link error.
It is not that I don't like passing by reference, it is just that I don't
understand why they are passing by reference. Do streams always
have to be passed by reference?

Passing by reference ensures that the stream objects aren't copied. When dealing with streams this is extremely important. You can think of the iostream library as very smart wrappers for handles.
The constructor initialises the handle, and the destructor frees it.
If you copy a stream you get a copy of the handle, but you will end up trying to free the handle twice, once at the end of the local block and once at program shutdown.
As a rule of thumb:
For input only paramters
1/ pass by const reference (objects or anything expensive to copy)
2/ pass by value (primitive types)
For output or input/output parameters
1/ pass by reference
If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts you aim;
Yours is the Earth and everything that's in it.

In 6.0 "#using" is not a valid command. I want to do this:
#using <msimg32.lib> but it won't let me. How do you say that in 6.0?
LOSTTWARE.com
|
|
|
|
|
#pragma comment( lib, "msimg32.lib" )
This embeds a command to the linker in the object file generated by the compiler for this source file. MFC uses comment pragmas to force linking to the appropriate MFC runtime library files depending on your definitions.
The #using directive is for importing a managed library for use in managed C++ code.

Hi there,
I am using pattern brush to fill a rectangle. The Pattern is displayed perfectly but when I print it, the pattern becomes so small that any one could hardly figure it out. This is because higher the printer resolution, higher the density of pattern per inch. So I need a way to change or decrease the printer Resolution or the DPIs at run time. Can anyone help me out?

Hi,
has anyone an idea who to loop through all Outlook Folder (the default Folders and the folders who has someone created) and
save the data for example in a text file.
To save it in file is not the problem;
but how can I "automatically" loop through all outlook Folders ?
You know, I´m using C++ and the wrapper classes from the outlook typ libraries.
Thanks a lot !

In the Outlook object model folders and subfolders can be accessed through:
Outlook::MAPIFolder - represents a folder or a subfolder under which messages exist
Outlook::_Folders - represents a collection of such MAPIFolders.
You can get the toplevel collection of Folders from the Namespace object like:
<br />
<br />
CComPtr< Outlook::_NameSpace > spNamespace; <br />
spNamespace = spApp->GetNamespace(OLESTR("MAPI")); <br />
ATLASSERT(spNamespace!=NULL);<br />
<br />
<br />
CComPtr< Outlook::MAPIFolder > spFolder;<br />
CComPtr< Outlook::_Folders > spFolders;<br />
<br />
HRESULT hr = spNamespace->get_Folders(&spFolders);<br />
if(FAILED(hr))<br />
return hr;<br />
<br />
long nb_items = -1;<br />
spFolders->get_Count(&nb_items);<br />
<br />
<br />
for(int l=1;l<=nb_items;l++)<br />
{<br />
spFolder = spFolders->Item(CComVariant(l)); <br />
ATLASSERT(spFolder);<br />
<br />
CComBSTR bstrFolderName;<br />
hr = spFolder->get_Name(&bstrFolderName);<br />
if(FAILED(hr))<br />
break;<br />
<br />
ATLTRACE(bstrFolderName);<br />
_FoldersPtr subFolders;<br />
hr = spFolder->get_Folders(&subFolders);<br />
hr = EnumerateSubFolders(subFolders);<br />
<br />
}<br />
<br />
for instance to get to my Outlook Inbox, I have to drill down the object model such:
Personal Folders
|Inbox
|Outbox
|Calender
|Drafts
|other folders
Other .pst file
|Chapter1
|Chapter2
IMAP account
|Inbox
etc etc.

Well, You will have to distribute crystl32.ocx on the user's PC and need to register that OCX as well. You can see this file name while importing crystal reports control in your project. So Just check it out.

Thanks for ur help. i already added crystal report ocx control crystl32.ocx in package & deployment. what problem i facing is while installing my application in my client machine. this control registration is failed. database is mysql. database connection thru ODBC. i package & deployment project i add this activeX in system folder. there is any files needed for this. if you have any idea tell to me.
thanks in advance

Try Registering the component manually using 'regsvr32' command.
The Syntax:
'regsvr32 <full path="" of="" the="" ocx="">'
After issuing the command, check out the error message if any and do it accordingly.

The crystal components depend on MANY dlls. Depending on what features you are using in your reports, different dlls are used. I strongly suggest you read the programmers manual. There is a section on dependencies.

Or run your VC6.0 tools - depends to check your DLL dependencies.

Hello, Sir:
Now i have a trouble with how to get CD-ROM(DVD-ROM) informations in windows platform.

I have a little about that, I just hear that the informations can be get by ATA command, but i don't know how to get the informations on windows platform. Can you give me some advice? I need your help. Thanks

try GetVolumeInformation() function.
|
|
|
|

Thanks sir.
But i have a look about GetVolumeInformation() function in MSDN. I know this function maybe can get a cd media information, but i wish get the cd-rom hareware information, includeing the vendor, model name, firmware version, and so on. I am not means to get a media information in CD-ROM drive.
I know that this cd-rom hareware information can be get by ATA/ATAPI command. I want to know obtrusively, Are you know that? Thanks you reply.
