I suggest using vector or, if in MFC, CArray. Both use the heap, instead of stack, and maintain the count.
Option 2 is to simply use:
char* pStr = new char[255];
But make sure you delete it when you got out of scope (or use a smart pointer class.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

this is certainly a stupid question for the ones of you who know the answer, but the fact is that i never went into multi-projects workspaces (under VC++ 6) / solutions (under VC++ .NET 2003).
there are 2 main cases where i want to do so :
1) one project is the main application UI, the other ones would be DLL project (needed by the GUI)
2) One project is the application, the other project would be a unit test project.
i don't know how to proceed neither one nor other case.
my simple question is : how are set/used the dependencies (say, for VS2003), so that i don't have to copy the classes files (headers && implementations) from one project to the others ?
thanks to all of you who can provide a useful information.
[edit]
I'll go in a simpler question if no one knows :
how do you design a solution which has several projects in it, where one need to use some classes defined in another project of the solution (without copying the files between the projects folder ; only by dependencies) ??

I am not sure if this is the answer. Try to use 'reference'. In vs2003, use
Project/Properties, then at 'References' in "Common Properties", using "Add new reference" also set the path to the other projects. In the new window, select the correponding project you need, then it is done.

Hi writing a VC++ 6.0 application and I need to obtain the status of a printer and PRINTER_INFO_2 structure does not work, so I'm looking for some example code that uses SNMP MIB I know it is possible to query the printer to obtain this info but how in C++ using SNMP ?
Any info/inks etc would be appreciated

What is it that you are looking for that is not in that structure?

Hi David, thanks for the quick reply, my application always retruns in the status dword 0 ... even when the printer is offline, or the printer has the top cover open, or a tray open it always returns 0.

Hello.
How can I find out what files on my computer are being modified? And not by scanning every file. Something like task manager maybe...
Thanx.

Thanx. But that is an executable. I was searching for some source code, or even some main directions so that I can build my own '.cpp'. I only need the path of the files in the form of a string.

It helps to be as specific as possible. That article goes on to say what is required. Creating device drivers is no trivial task.

How about using the CDirectoryChangeWatcher class that is on codeproject ?
|
|
|

That would not work unless something about the file was changed.

I am writing a MDI database app using a splitter window (upper pane = parent table) (lower pane= child table) and am unsure as to the responsibilities of each class. I have it working but am always trying to better myself.
I have a database object (CDatabase)
I have a recordset object (CRecordset)
I have a document object (CDocument)
I have several views (CFormView)
I have a CSplitterWnd hosting the CFormViews
I realize the document holds the data. So here are my questions
I have seen an example where the document holds a member variable of both the Recordset and the Database and am currently adopting this scenario.
But which class is responsible for actually creating the recordset or does it matter? I currently have the document creating the database and each formview class responsible for creating the recordset of its pane. My document holds a member pointer of the recordsets created in the view
Is it appropriate to use the UpdateAllViews from the CDocument class to invoke the OnUpdate of each view? Then overide the OnUpdate in the view class to run a requery and other housekeeping procedures. Normally I associate the UpdateAllViews with some sort of visual activity in the Views but with a database it's all about requerying and housekeeping.
Thanks

It depends.
IMHO, it would be much better to hold your CDatabase and CRecordset objects together in the CDocument-derived class of yours because they are essentially serving the same purpose - to link your views to data. However, if recordset objects are subject to heavy dynamic user-invoked changes, I'd normally prefer to associate them with views.
That's what I think, although it's so much more a matter of preference than of being right or wrong...
