I have been scouring the web, msdn, and the help files trying to figure out how to do this, and have gotten nowhere except a web of abstract articles on Active Directories, and I'm not really sure A.D. is what I need to use to do this.
 Can someone please point me in the right direction?
Thanks in advance for any help you can give.

Extra Details, just in case they're relevant:
I'm using DAO to access a database on another computer on the network, which fails if the local machine does not already have an open connection to the server computer. I'm looking to check for the connection before opening the DAO object, and create the connection if it's not connected.
I have serviceable, though not pretty, methods for checking the connection, but have no idea how to create it.)

To simplify the process, this is the code snippet to open a DB that uses the default system database (usr/pass db).
#include <afxdao.h>
CDaoDatabase* daoDB = new CDaoDatabase();
try {
daoDB->Open("\\\\Main\\E-Drive\\DB\\Operational.mdb", false, true);
} catch (CDaoException * daoE) {
return false;
} catch (Exception* e) {
return false;
};
if (!daoDB->IsOpen()) {
return false;
};
Thanks again,

So what exception is thrown, or what error do you receive?

The daoDB->ReportError() method reports:
The Microsoft Jet database engine cannot open the file '\\Main\E-Drive\DB\Operational.mdb'.
It is already opened exclusively by another user, or you need permission to view its data. If, however, I open My Computer and type '\\Main\E-Drive\DB\' (or any valid path on \\Main) in the address bar, it prompts me to enter my user/pass, and then displays the contents of the drive/folder.
After doing that, if I run the program again, I will no longer receive the error message and the DAO engine can access the file without issue.
(It also works if I map a network drive to some share on \\Main .)
My problem is that I can't seem to find a way to programatically connect to \\Main so that the share can be accessed.

Would is be acceptable to call NetUseAdd() first to map a drive letter to \\Main\\E-Drive, and then use that drive letter in the call to Open()?

I don't know how none of my searches turned that up, but thank you. I pulled up NetUseAdd in the help file, and the first thing (ok, second thing) it says is that you don't have to actually map the drive - you can use it to just authenticate with the server for future transactions. This should be perfect!
Thanks, Mr. Crow - what a great help!

Hello,
I am using an user defined List Control in my application. (CXListCtrl provided by Mr. Hans in Code Project).
If any other window (whose size is less than the size of Control size) is placed and removed that area is not repainted. When I checked OnPaint () of the implemeentation of control is left for default by calling Default () function. I tried to replace Invalidate () before that but it goes for indefinite loop as Invalidate () also invokes OnDraw function.
I tested by invoking a notepad making the size of it less than the size of List control, place it on top the control and switch back to my application. I find the area of notepad being blank. Placing some TRACE Message I found that OnDraw () function of the control is called when i do that test. But since Default () function is called it is not painting that area.
Can any one suggest me what can be done to avoid the repainting problem?
I am developing an MFC SDI application in .NET environment on Windows XP.
Thanks for your Time

Hi I am building a client/server application based on TCP/IP. The Server is running and client can connect to it. Now I want to show a Folder Dialog on client that lists the contents of Server. The client needs to select a folder on Server.
Anyone with suggestions? code examples?
thanks

Imho, the appropriate way to do this is for your server to support a request that lists the contents of a folder under its control (much like an FTP server, a nice sample of which can be found here[^]). The client app will make requests off the server as and when it needs to expand a folder in the tree control displayed to the user.

Hi Friends
Do u have any idea for comparing two bitmaps images . Any code in c /c ++ ?
thanx in advance 
|
|
|
|
|
What do you want to do ? Can't you simply check if each pixels are equal in both images ?
|
|
|
|
|
Cedric I think that this isnt a good way but possible that he check for each pixel in bitmaps in a loop(only a for)
but usually width and height aren't equal
so 1-first create a bitmap in screen that width and height are same(800x800) and draw bitmap in this screen also for bitmap2
then in one loop read pixels from bitmap1 and bitmap2
Is it possible?
|
|
|
|
|
I don't think the problem is defined well enough for any kind of reply. Do the bitmaps have noise? Like, for example, the ones that come from a live camera? Or are they synthetic (computer generated)?
What does the comparison try to obtain? The diferences? In which form? In the form of a diferential image? Or in the form of a list of diferene regions and their bounding boxes, for example? Or does the comparison result in a flag that says something like "image 1 = room empty", and "image 2 = intruder detected!!"?

The basic concept is simple - prevent any new windows from being created. Things get a little complex when you have to differentiate between intentional creation of a new browser window by a user, and malicious ones. Even moreso if you start doing things like examining the HTML document for onload Javascript events, or rewriting the HTML script itself.
For a start, take a look at the WebBroswer Control documentation in/on MSDN, especially the DWebBrowserEvents2 interface and the BeforeNavigate2 and NewWindow2events.
Peace!

Hi again i have a strange question to ask i'am not sure if it is applicable but if there is a way to do it here is right place to find out.
i'm working on the implementation of a spam filter and i'm trying to implement a function that extracts the fonts color and the background color from an html file.
What i'm trying to do is check if the font color and the background color are similar (invisible text, common in spam emails) i get the bgcolor and font color in hexadecimal format and i was wondering if there is a class to compare the colors. i found something similar but for c#.net is
System.Drawing.Color cfg = System.Drawing.ColorTranslator.FromHtml(foreColor);
if (cbg.R <= cfg.R + 15 ||cbg.R >= cfg.R - 15)
{
if (cbg.R <= cfg.R + 15 ||cbg.R >= cfg.R - 15)
{
if (cbg.R <= cfg.R + 15 ||cbg.R >= cfg.R - 15)
{
return fsi;
}
}
}
Any ideas
Thanks in advance

You mean in a string ? Or how is this value stored ?
Anyway, you can simply compare the strings or the values to check if they are the same or not.

Thanks for the reply cedric Moonen
i store the the colors which are in this form #CC0000, #EA0000, #5E5EFF
the problem is that i can't just compare if they are the same because most of the times they use simmilar colors for the bg and fonts but not identical for example white bg and very light yellow for the fonts still unreadable but it won't match if i compare the colors
