Re: CreateDirectory w/ permissions

1-Dec-04 12:12

How does one create a directory using CreateDirectory() with permissions of the parent directory ?

This is knowing that the parent directory can be access by all users who login to the system (computer).

Thanks in advance

MSDN says for CreateDirectory()

If lpSecurityAttributes is NULL, the directory gets a default security descriptor. The ACLs in the default security descriptor for a directory are inherited from its parent directory.

So if you pass NULL in for the lpSecurityAttributes parameter, does that work? What permissions does the created directory have when you create it, if they aren't those of the parent?

Set tab order of controls in VC++ 7

After migrating to the new Visual Studio .NET 2003 IDE from Visual Studio 6, I am having a hard time finding the "set tab order" thing. The documentation claims this is under the view menu, but I can't see it.

Anyone tried to set the tab order for a CFormView in an MFC app in the .NET IDE? Is this just another one of those things that no longer works in the new IDE, that used to work in the previous?

Thanks

Yes... it's NOT under the View menu. Look under the Format menu. Format->Tab Order

Hello !

When i add "Microsoft FlexGrid control, version 6.0" to my dialog, it open a message box with a error text line below :
The ActiveX control cannot be instantiated.
And:
The ActiveX control "Microsoft FlexGrid control, version 6.0" could not be instantiated because it requires a design time lincese.

What can i do ?

I used Visual C++ 6.0

Please help me.

Thank you.

Try this: http://support.microsoft.com/default.aspx?scid=kb;en-us;194751. I realize it isn't referring to VC6, but it's the same control, and the same issue. If it isn't licensed for one, it wouldn't be licensed for the other.

Hello,
I have written a C++ program. I have compiled,built and executed the program. It works fine. I want to be able to send the output on the screen to a printer. How can I nclude this option. Can I use MFC? In other words how do I display my program on a page that contains the options for print view, print,save etc.

Thank You

Have you considered:

FILE *pOutput = fopen("LPT1:", "w");
fprintf(pOutput , ...);
fclose(pOutput);

First off I have seen you post this at least 4 times. Yet, everyone who responds seems to be thinking like a rocket scientest. For anyone who reads this, all he wants to do is provide printing options for his program. i.e. File ... Print. It's a simple concept.

From what I've read over the last week or so, he has a console application that does a bunch of stuff and displays it on the screen in the console. All that he wants to do is print what's in the console. So anyone that knows a simple way of printing from the console, post it, so we don't have to continue reading the same post.

Brimid, I told you before, go to the printing section of this site and read some of the articles. I'll even point a few out to you in a few mins. I don't know what to tell you about using MFC, because its not something you can just jump right into and understand. It takes time. But I'll go find a few articles for you to look at anyway.

Here's some links.

http://www.codeproject.com/printing/printing_wo_docview.asp[^]

This is an article showing some generic printing functions. It's what I used to learn how to print. It uses MFC however. If your program isn't real big I might be able to help you out.

http://www.codeproject.com/printing/printingtricksandtips.asp[^]

There's some good tips in this article.

http://www.codeproject.com/printing/printmechanism.asp[^]

This article might help, haven't really looked at it much though.

Again all of these use MFC and if your program isn't too big, maybe I can help you out with it.

CArray RemoveAt Questions

#include <fstream>

int main(int, char*)
{
   ofstream Printer ("lpt1:");
   Printer << "Test" << endl;
   return 0;
}

Works if the printer is connected to your parallel port, not sure about USB printers.

Hi all,

I got a really weird problem when I tried to use RemoveAt() function to remove elements from a CArray.

I have two parallel arrays called carrURL (a CString array) and carrHit (an int array). What I want to do is:

If an element in carrURL has duplicated elements, then add its corresponding values from carrHit together and then remove these duplicated elements from carrURL. If an element is unique in the array, just keep it and go next.

For example: suppose carrURL[0], carrURL[4], carrURL [100] are the same string, add the values of carrHit[4], carrHit[100] to carrURL[0] and remove carrURL[4] and carrURL[100] (also remove carrHit[4] and carrHit[100]).

The code is below:

for (int nIndex = 0; nIndex < carrURL.GetSize(); nIndex++){
for (int ncItem = nIndex + 1; ncItem < carrURL.GetSize(); ncItem++){
if (carrURL[ncItem].Compare(carrURL[nIndex]) == 0){
carrHit[nIndex] += carrHit[ncItem];
carrHit.RemoveAt(ncItem);
carrURL.RemoveAt(ncItem);
}
}
carrHit.FreeExtra(); // free extra memory
carrURL.FreeExtra(); // free extra memory
}

However, the result is not what I supposed. It shows something like that:

carrURL carrHit
a 500 -- good
b 333 -- good
c 450 -- weird!
c 61 -- weird!
d 11 -- good
e 10 -- good
c 1 -- weird!

I can't understand why there are still some duplicated values which can not be found out after running a proper loop.

Any suggestions?

Thanks a lot!

Each time you call RemoveAt() the size of the array reduces by 1. GetSize() may therefore not give you the result you expect!

A better way would be to replace the elements to be removed with "special" values (like empty strings and -1, for example), then remove those elements in a 2nd loop.

try removing items from the end of the array instead of the start.
