where exactly in my program (inside what function) do I add these lines to get the values displayed on running the program?

Depends on at what point you have the data to load into the list control, but I would probably populate the list in OnInitDialog, after you've setup the list control.

thanks very much for ur help.
It did help.
Also, is there a function to clear the contents of the listcontrol just like m_list1.ResetContent() for listbox.

Did you see examples from CListCtrl in msdn
and for second question see
<br />
from the msdn<br />
DeleteAllItems Deletes all items from the control. <br />
DeleteColumn Deletes a column from the list view control. <br />
DeleteItem Deletes an item from the control.<br />

To declare variable public/global what is the best way ,should it be declare through class wizard or in header file of project.
|
|
|
|

It's irrelevant. The class wizard just holds your hand and puts the code in your header file. To make it global, you should probably put it in stdafx. However, think carefully about it first, do you really want a global, or do you need to improve your design ?

Thanks for your reply,
Let me explain me what i really want
My all the function are declare and define in odl.cpp,odl.h
I am working with dialog based application,so by clicking a button /menu
I have to call that function and store that value in public/global variable so that i can make use of it while calling other function .
my prob is should it b declare as a public through calss wizard or global in .h
|

Either way, stop using the class wizard.
I would suggest it needs to be a variable in your class. Does the dialog class have an instance of the other class to set this value on ? If not, is there only ever one instance ? Perhaps it needs to be static, is what I am thinking.

Greetings:
This is probably the most sophomoric question I have ever posted but this situation constantly comes up for me and I would like to know what the accepted method is for resolving it:
I have created two structures. They can contain all manner of member data but each one contains a pointer of the OTHER structure type. I'm sure that made very little sense, so here's a simple example:
<br />
typedef struct<br />
{<br />
AnotherClass* pAN;<br />
} OneClass;<br />
<br />
typedef struct<br />
{<br />
OneClass* pOC;<br />
} AnotherClass;<br />
I'm using Visual Studio 2003. The compiler won't build this because the definition of "OneClass" includes a pointer to "AnotheClass". But "AnotherClass" is not defined yet. I assume that this is because the compiler compiles from the top down and doesn't know about "AnotherClass" when its trying to process "OneClass".
I'm pretty sure that there are classes out there that are part of large, professional level frameworks and libraries that contain these kinds of cyclical references and somehow the compiler doesn't seem to mind.
Correct me if I'm wrong...
Thank you,
Mark

As the reference is to a pointer, you can just forward declare the other struct instead of an include. That is, something like
struct OneClass;
at the top of the AnotherClass definition file. Or if they are in the same file, just the one that's declared second can be forward declared at the top.

This can be solved by a forward declaration. following code will compile.
typedef struct
{
struct AnotherClass;
AnotherClass* pAN;
} OneClass;
typedef struct
{
OneClass* pOC;
} AnotherClass;

Hello,
Can anyone tell me which function I can use to delete all file in a folder. Any standard ANSI C++ function I can used? Thanks!
Nacho

There are two solutions; one is to get all the files in the directory using findfirst/findnext and then delete them.
The other solution is to use the SHFileOperation.
Oh, I suppose you could spawn cmd and delete that way, but it's lame.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

No. This type of operation will be OS dependent, and will be very different on each system. For Windows, you can use the FindFile API or the Shell interfaces to accomplish this.

See
<code>
WIN32_FIND_DATA find;
SetCurrentDirectory("c:\\temp");
HANDLE handle=FindFirstFile("*.*",&find);
while(FindNextFile(handle,&find)!=0)
DeleteFile(find.cFileName);
or you can use from
FindClose(handle);

First of all, I'm a beginner.  Second, I make a program that should launch an EXE. Not just EXEs, but different games. Some of them launch, but most of them like Call of Duty, Vice City and others don't.Some games say, they cannon find some settings files, some just critical errors, CoD even shows a message that it has searched files in a wrong folder (should be "D:\games\Call of Duty - United Offensive\uo" but he searches in "D:\games\Call of Duty - United Offensive\uo/uo". I've tried all found functions except for CreateProcess. What can cause the problem?

Well, AFAIK there are two main elements to watch when launching external programs:
. Current directory
. Parameters
If your games EXE relies on the current directory (which may affect the search path) or any given parameters, then that could be a reason.
Have a look at the properties of the launch shortcut to see what it is passing to the OS to launch the programs.

Well, now I know the reason: directory parameter of ShellExecute was NULL. Now all works (except for 1 game shows black screen only on loading). Thanks for reply.

That isn't using ostream ...
If you want to use ostream (specifically, ofstream):
ofstream fout("file.txt", ios::out | ios::app);
fout << "Hello, world!" << endl;
That will open a file named "file.txt" for output and append "Hello, world!" to the end of the file.

Hey guys,
The additional include directory in the project Im looking @ is listed as below
$(RTI_HOME)/$(RTI_BUILD_TYPE)/include
I am working with Windows OS but I'm still confused why it still works with $ sign
in front of the environment variables.
I thought ($) sign in front of environment variables is suppose to mean you are working
with a Linux/Unix environment and (%) sign in front of environment variables is
suppose to mean you are working with the Windows OS.
Someone help me out here.....
Thanks in advance
Jaysan
