Hi,
I have an application that uses the cluster-api (clusapi.dll) on Windows Server 2003. When I run my application under the Administrator account the call to the method OpenCluster works fine, but the problem is that not all users of my application are in fact administrators and when I call GetLastError after the call fails it says: Access is denied
I realize that someone belonging to the Users group are not allowed to make that call, but I can't find in MSDN (or anywhere else) why this is the case and I'd like to check if anyone knows a way around this.
This code always returns NULL since hCluster is NULL after the call to OpenCluster:
HCLUSTER hCluster;
hCluster = OpenCluster( NULL );
if( hCluster == NULL )
{
return NULL;
}
I'm more used to C# coding, but I have written a dll in C++ containing all the cluster functionality I need (and then using that dll in my C# project via p/Invoke).
Any ideas around this would be appreciated.
Thanks!

If you did find a way to circumvent security and Microsoft found out, they would likely fix the security hole and then the work around would no longer work anyway. It would be safer to just follow guidelines.

I guess you're right lm - thanks for your reply. So this is obviously done by design from MS. Well, do you know if there is a way to find out if an NT Service is part of a cluster group? That's what I really need to find out.

No, I have no experience with that scenario. Have you looked at the clustering API documentation[^]?

Yes I have, but no luck yet 
Well, thanks anyway!

Sure, it sort of makes sense since the point of clustering/balancing is that you should not have to know which specific machine something is running on. If I were in your shoes, I would want to make sure there is an actual need for what you are trying to do. It seems contradictory.

Hi, I have only recently got back to VC++ programming and I was only a rookie when I used to program in it but now I need to create an application that can list all the devices attached to the system like "devcon.exe" does. I only just started coding it and I'm now facing a linker error that I just can't resolve! The path to my SETUPAPI.h file exists in the "Directories" under options. And I'm only calling the "SetupDiGetClassDevsEx" function. The program compiles fine but gives the following error while linking:
DeviceMDlg.obj : error LNK2001: unresolved external symbol __imp__SetupDiGetClassDevsExA@24
Debug/DeviceM.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
DeviceM.exe - 2 error(s), 0 warning(s)
Please help! I'm losing my mind!
Thanks and sorry if it's a really stupid question
*** What do you mean add SetupAPI.lib to the linker files list?? Paths of both header and lib file are listed under the "Include files" and "Library files" options. Also SetupAPI.h and .lib are present in the default path ~/VC98/Include and ~/VC98/Lib. I didn't add any external library. Any ideas??

You should add SetupAPI.lib to the linker input files list.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I'm sorry if I didn't specify it earlier but please look at the extra detail I've added to the end. Is there anything else I need to do too?

I've also noticed something now. MSDN shows that SetupDiGetClassDevsEx accepts 7 parameters but I guess VC++6.0 uses an older version as the SetupAPI.h header file in the default path(~/VC98/include) accepts only 6 parameters. So I tried to use the header and lib files available with Windows DDK which has SetupDiGetClassDevsEx with 7 params. But the two seem incompatible as now it shows me 37 errors at compile time, all in the header SetupAPI.h. Any help about how to handle this?

You should explicitely add SetupAPI.lib to the list of the linker input files (I suppose it is in Project Menu->Settings, Link tab, Category->General->Object/library)

How to load and display an image in C++? 
|
|
|
|

#include "AtlImage.h"
cImage m;
m.Load(_T("C:\\1.jpg"));
m.BitBlt(0,0,640,480);
Of one Essence is the human race
thus has Creation put the base
One Limb impacted is sufficient

Do you pay for each keystroke?

More information would have been very useful. What type of image is this (bmp, jpg, ...) ? How do you need to display this image ?

I need to display a grayscale image as i m working on eigenfaces for face recognition

Great, but what about the questions I actually asked ? 
|
|
|
|

It depends below.
1) what type is that image
2) what is the display device
3) what platform or os do you use
4) what do you plan to use library for image processing
fro example,
1') windows 24 colored bitmap
2') windows crt screen
3') win32 platform
4') use simply win32 GDI api
You can write codes with above condition. It is very ordinary image processing but coding is a bit messy. MSDN tells you some sample codes kindly.
And also
4'') you can buy some image processing library
Paying usually makes you easier to write codes.
