Hi,
I have a simple program that uses WIN32_FIND_DATA with the usual GetFirstFile() GetNextFile() etc.
What I need to be able to do is find out if the directories I pass through are Indexed or not.
I cannot see an Indexed Attribute in WIN32_FIND_DATA, so that it obviously not the place to look.
Also, is there some way to programmatically set a Directory as Indexed?
Visual Studio 2008, Vista 64 Bit.
Thanks for any advice,

Now assuming that the target system is using NTFS, the Indexing service is running and that the folder you are interrogating is included in the list of items the service will index THEN the file attribute FILE_ATTRIBUTE_NOT_CONTENT_INDEXED[^] is your best bet.
Check Win32_ServerFeature in WMI for ID
71 Indexing Service
Then look at ISearchCrawlScopeManager[^] at ways to query the indexing service.
Hope this helps.Alan

Hi Alan,
looks like there is a bit more to this Indexing Service than just getting an attribute bit...
It seems to me that the FILE_ATTRIBUTE_NOT_CONTENT_INDEXED is saying that the associated file is to be excluded from Indexing, so is not too useful for my purposes.
I have been looking at the OLE DB Provider and its interaction with the Indexing Service, but this "simple" project is not going to be as easy as I had hoped.
So I will leave this one on the back-burner for now.
Thanks,
Bryan.

Wouldn't the lack of the FILE_ATTRIBUTE_NOT_CONTENT_INDEXED bit being set indicate this it is being indexed?"One man's wage rise is another man's price increase." - Harold Wilson

| True. IF, and it is a big one, you have the index service installed, running and the folder was in the list. Alan

The problem I have is essentially very simple.
I need to have multiple CDialog thread in my application that do not lock the primary UI thread. Their purpose will be to display specific data in each one.
My problem is that although I have been able to achieve this for one of the dialogs by
public:
CSimulator thSim;
...
thSim.CreateThread();
but any attempt I make to repeat this approach does not give me the dialog although no errors are generated at compile or runtime.
I have also tried using the
OnInitDialog() of my main dialog but this just results in the main dialog having the child dialog pasted over it. Not pretty.
Ultimately I am planning to use an SDI for the main interface with CDialog's for the children. This would allow the child dialogs to be arranged across multiple montiors independantly of the main UI.
Whilst MFC is quite an old thing to be using I have to be sure the application will run on ANY Windows platform without having to worry too much about dependancies (i.e. from XP to Windows 7). Also the target machines are tightly controlled so adding .Net to them is a no go before anyone suggests it.
So does anyone have any suggestions how best to create and manage multiple CDialog's?
Many thanksAlan

If I am understanding this correctly, your difficulty is that you are attempting to use modal dialogs. What you want is to use modeless dialogs. These are still based on CDialog but have some differences in what you need to do in some overridden methods and how you start them up. You do not need a seperate thread to run them, they are just fine on your main UI thread. I have talked about them before in this post. I haven't double checked if I have everything in there that you need, but there is at least a good part of it. This should give you some direction. If necessary I could try to fill more stuff in, but I have to head out to a baby naming this afternoon and have a six hour drive tomorrow, so I'm leaving it at this for now.
Good luckPlease do not read this signature.

| Thank you for the suggestions. Modeless sounds like it could be what I need to do. I will experiment with your suggestions. Alan

Thank you for the suggestions and Modeless certainly works to a point.
Sorry if I am being a newbie but I have spent most of my time deep behind the UI so this is all a bit of a novelty.
The problem I have now is that when I spawn the modeless dialogs, overlapping them causes painting issues. i.e. each dialog becomes contaminted with whatever was infront of it when it takes focus.
Oddly this is does not happen on Windows 7 which is my development platform.
Now I am assuming this is because I am not handling the change in focus correctly, which I am looking into, but any suggestions?
I have to be able to spawn between 2 and 255 of my modeless dialogs (yes I know it is a lot) and be sure that they all repaint correctly.Alan

Hiya,
I need to send images to a server and want to use Base64 encoding.
Is there currently a library that will do this for me?
Thanks,

Hello,
I've got a question about variable argument list: Is there a possibility/what would be the best way to call a function with variable arguments, but the number and the type of the arguments is not know at compile time?
You could imagine the problem as follows ( printf is used here for simplicity):
You have an input txt file with the string and a variable number of parameters on each line:
e.g.
"id=%d, name=%s, age=%d" 1 "marci" 100
" a totally different string %d %d %c %x" 1 2 'Y' 10
" there is no rule, this string can be %s" "anything"
You have to use these inputs in the code as parameters for the printf function.
(e.g. for the first line printf("id=%d, name=%s, age=%d",1,"marci",100);
Thank you in advance,
yakabmarci
P.S. The resp. function is available as both as func(n,...) and func(n,va_list p)

i'd put the parameters into an array of strings. or, if you can derive all of your parameters from a common base type, put them into an array of CBaseType*s. then pass the array - it's cleaner than dealing with the varargs stuff.

i want to connect my application to all servers on LAN using TCP sockets.
UINT CD1MessageDlg::ScanLAN(LPVOID pParam)
{
unsigned int tf0, tf1, tf2, tf3;
CString tip = "";
CD1MessageDlg *t;
t=(CD1MessageDlg*)pParam;
BOOL x = 1;
for (tf0 = 192; tf0 <= 192; tf0++)
{
for (tf1 = 168; tf1 <= 168; tf1++)
{
for (tf2 = 109; tf2 <= 117; tf2++)
{
for (tf3 = 1; tf3 <= 255; tf3++)
{
tip.Format("%u.%u.%u.%u", tf0, tf1, tf2, tf3);
t->m_sConnectSocket.Connect(tip, 50000);
}
tf3 = 0;
}
tf2 = 109;
}
tf1 = 168;
}
return 0;
}
one more ques. can i reuse the same socket again and again for finding server as i'm doing in my this code.Future Lies in Present.

you probably can - but if you fail to connect your socket will 'block' for the timeout, so you may want to use a socket pool
furthermore,

loops are redundant, and in

you're not specifying a port - so what do you hope to connect to ?

this code is for only testing purpose. i will modify my function to take ip address range from user.

my mistake - I had forgotten the Connect() parameters - I was thinking you were specifying the timeout ..
in which case, as I said, if you get a connect fail, you'll have to wait for the timeout for the socket to become available again I think ...

Consider the possibility to use "multicast" http://en.wikipedia.org/wiki/IP_multicast[^].
Check with your network administrator if this is possible in you environment, before spreading a potentially huge number of independent identical flows, or you may risk to sit down your network.

Hello all!
I am currently not the best programmer out there but am learning every day! I am faced with a small problem though, I know what my goals are and want to start focusing on them but im stuck choosing a compiler.
I want to do embedded arm development and move into linux arm based development and driver/gui development but at the same time I gotta face the fact that 90% of the market is windows based so I will need to be able to write windows programs to communicate with my devices. My questions is should I dive into gcc with a full linux distro and do all my development on that and then use say Visual Studio to write all my windows based client software?
Another option is to use windows exclusively and say minGW with Code::Blocks or even setup a GCC toolchain (one for windows and one for arm using Cygwin) and using wxWidgets and QT/SDL based code for portability.
The main issues is I am still a beginner and should I go all out with the environment or choose one compiler to stick with for now? Im worried that changing compilers (especially from a VS MFC setup to GCC) will be a large setback so why not start out on the end road eh?
Thanks!

You are worrying too much. Both VC++ and GCC are pretty stndard compliant these days and you won't have too much troubles switching from one to another.

Hi Member
I found keyboard hook example from codeproject.
Click here
[]
And follow these step
1.Copy KeyHook.h, KeyHook.dll, Keyhook.lib into your project directory, add KeyHook.lib into your workspace by "Project - Add to Project - Files", and include KeyHook.h where needed.
2.Call InstallKeyHook to install the hook.
3.Call AddKeyEntry to register key entries which consist of information on what kinds of keyboard events should be captured and whom should be notified.
4.Call GetKeyEventResult to retrieve information of the captured key events after your application window receives the notification messages, with values of the wParam and lParam unaltered.
5.Call UninstallKeyHook to release resources as soon as you've finished using the hook.
But Nothing happen.
I just want to get key when Key is press on application(
application may be notepad,word or internet explorer).please help me
