Hi,
I wish to be able to delete a specifed section of my *.ini file. I have been adding things to it, but how do I delete things? I have been using the following code without the SetRegKey() function to create my .ini:
AfxGetApp()->WriteProfileString("Section", "Part", data);
I wish to delete the "Section". Code to the "Part" would also be appreaciated.
Thanks,

I have been using this to help me with ini files. http://www.codeproject.com/cpp/cinifile.asp
You could see how he does it then impliment that, or switch over and use this. It is fairly straight forward and clean. Hope this helps.

Excellent!
I wish I had known about that class sooner!

That class is indeed wonderful, but I'm just curious: Why isn't there a way to delete an INI section or entry by API calls? I've tried to search through MSDN and studied all(I think) INI-file-related API's, no lucky, i really can't beleive that.

You are always limited by Win32 API (actually, in this case it's inherited from Win16), and if Micros~1 didn't think of something you'd want to do, there us usually no documented way to do it.
Easy as pie (unless you try a GDI Pie...).

AfxGetApp()->WriteProfileString("Section", "Part", NULL) should delete "Part" from "Section".
AfxGetApp()->WriteProfileString("Section", NULL, NULL) should delete all of "Section".
See the documentation for ::WritePrivateProfileString and look at the source code for CWinApp::WriteProfileString. The documentation for CWinApp::WritePrivateProfile string apparently fails to mention that you can use it to delete entire sections from the INI file.

Before every function definitions, I have gotten into the habit of prefacing each with COMMENTS on what's being accomplished in that function (such as which parameters are input, output, and what changes were made to that function, when, and for what reason, etc.).
However (useful as it is), it has become something of a labor for which I would like to formulate a way in which I could do something that would automate the process of inserting a "template like" generic header, which I could then modify with only the specifics for that particular function.
IOW, my rough idea is to insert a macro (or something like that) before each function definition, and when the program is compiled, to have the macro expand into this generic template layout which I would then simply fill in with the relevant information (etc.).
Any idea on the best approach?
Thanks!!

Amazing that someone would promulgate this.
This sort of commenting has been discredited as very hard to maintain, and therefore more likely to be misleading than informative. Bad idea.

I don't see the problem, the guy asked for a way to add comments via macros, and a solution was given; whether the solution is good or bad, is another story, but the principles are there and it's up to the user to modify the script to generate his own good format for him.
Suggest another format!

I am not promulgating anything. I am the one asking for ideas.
Like everything good and beneficial, discipline is required if it's to remain that way.
I cannot count the amount of times I've had to spend hours playing detective to applications nobody seemed to remember what all have been done to it (not even the author who wrote it).
Tell me at such times you couldn't use all the help you can get (especially at 2 in the morning when your phone rings because some user on the other side of the world has just experienced a crash or some other anomally while using the application).
Nevertheless, I see your point, because of what good would documentation be if it's out of date and misleading, WHICH IS WHERE DISCIPLINE WILL HAVE COME IN.
Discipline is never easy. It requires (for a lot of people) training, consistence, and (for some) enforcement.
I like to think I'm helping out the next person whose phone might get ring at 2 in the morning, so he/she would know what to do and wouldn't have to call me (which in a way is helping myself).

I am not at my home computer, so I cannot research this up myself. What is the best/easiest way to search a directory and return the file name of every dll? Is it CFileFind()? Thanks for your help.

See MSDN:
FindNextFile
It has the sample code you want.

Would someone please look this over tell me if I got it right. I am not at my computer so I have no compiler to check it. Thank you.
CFileFind finder;<br />
static const TCHAR szFileToFind[] = _T("*.dll");<br />
Cstring Plugins[100];<br />
int tag = 0;<br />
bool bResult = finder.FindFile(szFileToFind);<br />
<br />
while (bResult)<br />
{<br />
finder.FindNextFile();<br />
Plugins[tag] == (LPCTSTR) finder.GetFileName();<br />
tag++;<br />
<br />
bResult = finder.FindFile(szFileToFind);<br />
<br />
}<br />
finder.Close();<br />

How do I get the rect of a subitem in a report-style CListCtrl? I'm wanting to paint icons in the subitems, but in order to paint icons there, I need to know where to put it  Basically, I just need a GetItemRect function for subitems.
Thanks!

Hi guys,
I've a declared bunch of global variables in
CMyClass
{
}
and I want to access them in CMyOtherClass. How do I do that?
Can I use extern? how about static? The compiler still warns me that I've "undeclared identifier" in CMyOtherClass when use those two keywords.
Help?

Then only in the .H file I should've declared the global variables, is that right?
Thanks.

I was thinking that you meant member variable because you said they were in CMyClass. If they are global variables, then they should be declared in 'MyClass.cpp' and extern in 'MyOtherClass.cpp'.

Let me answer my own question: FYI::
Put the global variables in the .h files and include the .h. and it'll be visiable to any class which includes .h.

You want to insert text at the bottom of the richedit control?
CHARRANGE cr;
cr.cpMax = LONG_MAX;
cr.cpMin = LONG_MAX;
richedit.SetSel( cr );
richedit.ReplaceSel( (LPCSTR)string );
richedit.SendMessage( SB_BOTTOM, NULL, NULL );
