Copying the PKCS#11 wrapper dll to the client machine in a signed applet

Hello,
I'm implementing in a signed Java Applet using the IAIK PKCS#11 Wrapper and the PKCS#11 module of my hardware token to communicate with it.
I have to copy the pkcs11wrapper.dll to the client machine. All things works perfectly under Windows XP but when the client have Windows Vista as OS, it's not possible to copy the needed dll.
Thank You for any help

How to link a wrapper DLL to the target DLL

I appreciate your help!
Question:
In my project, I need to deal with a hybrid programming of C++ and Labview. The C++ part has been encoded into a DLL, which aims to do a complex mathematics. The main function in the DLL has the following form:
                          float RateEqCalculate(class CLaserPulse *Pulse, class CMaterial *Material, class CThresh *ThreshPara, class CRateResults &r);
The four arguments are all of the class type. The first three arguments are used to input parameters to the function and the last one is used to record the process of computation. For example: class CLaserPulse is composed by several numerics and two functions as the following form:
class CLaserPulse
public:
float fDuration;
float fWave;
float fNA;
float fRefrIndex;                                    // Refractive Index
float fAbsCoeff;                                     // Absorption coefficient [1/m]
CLaserPulse();
virtual ~CLaserPulse();
virtual double Shape(double dTime);       // gives Temporal Shape
float SpotDiameter();                          // Calculate Spotdiameter
As in labview "class" cannot be accepted as an argument of the "Library Function Node" directly, a wrapper DLL is required to translate the "class" to the type labview can understand. The following link is a good illustration of this process. http://labviewwiki.org/DLL/shared_library Given the argument class CLaserPulse has been converted into the wrapper DLL by the method from the link, how can I later link this wrapper DLL to the target DLL. My understanding is like this:
                                                                                            Target DLL
                                                                               float RateEqCalculate(
  class CLaserPulse  ->   wrapper DLL       .........linking.........        class CLaserPulse,
  class CMaterial      ->   wrapper DLL       .........linking.........       class CMaterial,
  class CThresh        ->   wrapper DLL       .........linking.........        class CThresh ,
  class CRateResults  ->   wrapper DLL     .........linking.........        class CRateResults );
Am I right? Four wrapper DLL to four class type arguments?
Many thanks!!!

Hello Rolf and Christian:
Thank you for your suggestions! I'm now working on it. I appreciate your continuous help!!
I'll briefly summarize my question here:
In the original DLL, which is compiled by VC++ 6.0 and named RateEquation.dll, three class types (CLaserPulse, CMaterial& CThresh) are inclueded to do parameter exchanges; one class type is designed to save the calculation results(CRateResults);one main function to do the calculation and save the results as following form:
float RateEqCalculate(class CLaserPulse*, class CMaterial*, class CThresh*, class CRateResults &r);
My question now is the initialization of the struct type and the communication between this type with labview.
I'll take class CMaterial as an example to show how I made it into wrapper DLL.Original class CMaterial is defined as following:
class CMaterial
public:
float AbsorberGap;
float BandGap;
float CollTime;
float ElDensity; float RefractiveIndex;
float AbsorptionCoeff;
float MoleculeMass;
float Density;
float HeatCapacity;
float HeatConductivity;  float TAmbient;
CMaterial();
virtual ~CMaterial();
  In a wrapper dll it's like this:
WrapperDll.h
extern "C" { /*using a C compiler*/            //Using a C compiler to write the wrapper DLL
#endif
struct RATEEQUATION_API CMaterial{
  //Electronical properties
  float AbsorberGap;
  float BandGap;
  float CollTime;
  float ElDensity;
  //Optical properties
  float RefractiveIndex;
  float AbsorptionCoeff;
  //Other properties
  float MoleculeMass;
  float Density;
  float HeatCapacity;
  float HeatConductivity;
  float TAmbient;
typedef struct CMaterial CMaterial;                                             /* make the class opaque to the wrapper*/
RATEEQUATION_API CMaterial* creat_CMaterial(void);
RATEEQUATION_API void destroy_CMaterial(CMaterial* LV_ref);
#ifdef __cplusplus
#endif
WrapperDll.cpp
RATEEQUATION_API CMaterial* creat_CMaterial(void)
       return new CMaterial();
RATEEQUATION_API void destroy_CMaterial(CMaterial* LV_ref)
       delete LV_ref;
In function creat_CMaterial(), one can see the constructor of class CMaterial is called. As struct type CMaterial has the same memory layout as class type CMaterial, so it’s safe and possible to return a class CMaterial* to struct CMaterial* and it’s initialized by the default values in the class constructor. Now I’m confused by how one communicates between labview and struct CMaterial. For example, if I would like to change the parameter _CMaterial-> BandGap=6.5eV to 8eV. How to make it? My feeling is I need a cluster type from Labview as an input in the function creat_CMaterial:
                          CMaterial* creat_CMaterial(cluster_LV*)
Many thanks!

Copying client machine files into the Server BY Using APPLET

Hi there,
I created an applet which is DRAG and DROP enabled. In this applet content page i am dropping some file and trying to copy the same files in to the server. But when i am trying to save the files my code is saving the files in clients machine.
I thought we are embedding the applet in a browser and the applet is running in clients machine, so for the applet SERVER is the local machine and if we create any files then they will be created in SERVER machine.
But here the files are going to be saved in clients machine.
I SIGNED THE APPLET TO ACCESS THE CLIENT MACHINE FILES TO DRAG AND DROP INTO MY APPLET. THAT IS NOT A PROBLEM , BUT COPYING THE FILES FROM CLIENT MACHINE TO SERVER HAS BECOME A BIG PROBLEM
please any body can help in this regards?
THANKS IN ADVANCE.
batta

I cannot see how you will copy files From the Applet to the Server.
The only method I know to transfer data from a Java-Applet-Client to a Server and back is with the named method "HTTP-Tunneling".
This means your, your applet made a connection e.q with a Java-Servlet wich resides on a Web-Server.
This Servlet than can write to the Server-Filesystem and respond to the Applet.
May be you can reach a Server with PHP, but I have not yet experience with this (I did not found anything about Servlet-Response to the Applet).

How to obtain the Java environment in the already loaded dll

Hi all!
I try to implement a client GUI in Java. I load the static (c++) dll from the Java code, this work fine. But, I want to call also from the loaded dll to the client GUI, make a two-directional communication. How can I obtain the valid environment pointer in the c++ code?
Can you please help me?
Thanks very much
JAttila

There is a method that returns the environment.
But, I want to call also from the loaded dll to the client GUI,In response to what? If a thread then you have to also register the thread.

"The application or DLL C:/WINDOWS/System32/mssip32.dll....

-- is not a valid windows image. Please check against your installation and diskette.
I got this message after I had updated my itunes. Help please

+" 'mssip32.dll' is not and executable file and no registration helper is registered for this file type "+
Okay. somewhat experimental advice here, but I think it might be worth swapping your mssip32.dll for a new copy.
First, head into C:\Windows\System32\, find your current mssip32.dll, and rename it mssip32.dllOLD
Download a fresh copy of missip32.dll from here:
DLLDump.com: mssip32.dll Version: 5.131.2600.0
Move the new mssip32.dll into the system32 folder. (Where the old one lived.)
Now restart the PC and try another iTunes launch. Do you still get the Bad Image error (with a fresh mssip32.dll in place), or is it launching properly now?

Not using the most recent checked in version of the web app DLL in Release build

Hi folks
Got some peculiar behaviour - I have three build configurations set up within VS2K13 for Debug, Release and DebugOnLive.
There are some basic XML transformations to update emails, db-settings etc - all very simple and working.
Needed to do a DebugOnLive build to test an emergency fix and everything built fine. Tested on the pilot site, saw the fix was working and proceeded to rebuild for Release.
Everything seemed great except the web-app DLL with the fix in that was used for the release build was not the latest version even though the pilot build had used the latest version. I had to recheck in the DLL to get it to use the updated version!
Is this behaviour 'by design' - it seems peculiar you would have to re-check in to change the build if all you are doing is swapping some settings? You are fixed - all you are doing is building for a different configuration or am I misunderstanding?
mmacneill123 (MCP)

Hi Mmacneill123,
Thanks for your reply.
You said that “the issue is that I have already checked in the changes…”, and you said “if I check in before
EVERY build, everything works fine!” too.
You’re using the default build process template in your build definition? You configured these 3 configurations in your build definition to build your solution 3 times?
If you remove that DebugForLive configuration, only configure Debug and Release in your solution and build definition to perform build, everything will works fine?
After you changed the configuration from “DebugForLive” to Release, please check in on your solution first, then queue build definition to build your solution. After you changed the configuration each time, please check-in on your solution first,
then perform build.

Pages for iPad is not recognizing the password I assigned to a document. I included a hint, and I know I am entering the password that goes with the hint. Is there anything I can do to access my doc?

Pages for iPad is not recognizing the password I assigned to a document. I included a hint, and I know I am entering the password associated with the hint. Is there anything I can do to access my document? i quite the Pages app and restarted it. Now I guess I'll reset the iPad and see if that helps. Thanks!

Interesting that one does not need the password to delete using Finder.
The Pages password protects the contents of the document. If there were a Finder password, it would protect what you might think of as the "file wrapper" ... the stuff around the file content.
Glad it's not vital. I have to say I only pasword protect those Pages documents that are, in fact, vital.
Best of luck.

Thanks for your reply. basically this error occurs with in same location as well as branch location. i have check event log in AD but not got any specific error. AD health status is ok. AD to AD synchronization also working well. All the client machine running
on windows 7 64 bit and few of them are windows 8.
Please suggest. if you need any event log for analysis i can send you.
Thanks
I recommend you examine the event logs upon an affected client machine. Specifically, look for the surrounding events on that machine (both System, and Application logs), for the hours previous and the hour after.
The time period may vary according to your environment (e.g. what is expected/normal for your environment, your configured GP refresh cycle-time).
e.g., are there network drops, or power drops, or system crashes, restarts at the similar time.
if it's a laptop, is it wireless? Was there a transition from wireless to wired operation?
Is there VPN in use?
If you are able to compare with another machine (I would encourage that), to understand what "normal" looks like in the logs, so that you have some kind of baseline data for comparison.
Other checks, maybe confirm that the machines are updating as required (have the relevant WindowsUpdates etc), and consider if some security/protection/firewall software might be interfering with normal Windows operations.
Also the potential for malware or virus, which can disturb many basic services (ensure a scan is performed and returns clean).
If you have the opportunity for an affected user to contact you urgently when the symptom occurs, check that the gpt.ini file is accessible from their PC.
e.g.: \\example.net\sysvol\example.net\Policies\{31B2F340-016D-11D2-945F-00C04FB
984F9}\gpt.ini
This file is hosted within the replicated SYSVOL share on your DC's, so check that it is accessible.
You might also validate the particular GPO this refers to, and check each of your DC's holds the correct copy of the files for that GPO GUID.
If you open that GPO, and perform a minor change to it (e.g. add a comment), then click Apply, OK, this should cause the GPO contents to replicate an updated version (be cautious, depending upon the nature of that GPO !!!)

Reading Large data files from client machine ( urgent)

Hi,
I want to know the best way for reading large data at about 75MB file from client machine and insert to the database.
Can anybody provide sample code for it.
Loading the file should be done at client machine and inserting into the database should be done at server side.
How should i load the file?
How should i transfer this file or data to server ?
How should i insert into the database ?
Thanks in advance.
regards
Kalyan

Like I said before you should be using your application server to serve files >from the server off the filesystem. The database should not store files this big >and should instead just have a reference to this file. I think u have not understood the problem corectly.
I will make it clear.
The requirement is as follows.
This is a j2ee based application.
Application server is oracle application server.
Database is oracle9i
it is thick client (swing based application)
User enters datasource like c:\turkey.data
This turkey.data file contains data

like wise we may have more than 3 lacs rows in it.
We need to read this file and transfer this to the application server. Which are EJBS.
There we read this file each row in file is one row in the database for a table.
Like wise we need to insert 3 lacs records in the database.
We can use Jdbc to insert the data which is not a problem.
Only problem is how to transfer this data to server.
I can do it in one way. This is only a example
I can read all the data in StringBuffer and pass to server.
There again i get the data from StringBuffer and insert into database using jdbc.
This way if u do it. It is performance issue and takes long time to insert into the database.It even may give MemoryOutofBond exception.
just iam looking for the better way of doing this which may get good performace issue.
Hope u have understood the problem.

Trouble connecting to RDP from single client machine.

I have a Server 2012 machine running remote desktop services. Users at our branch offices connect to it over the corporate VPN.
It has been running for over a year now with no significant issues, until this past Tuesday.
I have exactly one client machine that immediately disconnects upon connecting to the machine. This does not generate very helpful error codes - On the server side, just a generic 4005 - The Windows logon process has unexpectedly terminated.
All other client machines can connect to the server without issue, including other client machines in that branch office. Furthermore, attempting to simply remote desktop into another 2012 server produces the same results on this machine, while remote
desktop to another windows 7 client machine seems to work just fine.
I have seen some similar problems mentioned, but they typically involve a server that consistently fails with all clients, whereas I have a single client machine that suddenly cannot RDP to Server 2012 machines. Any ideas?

Hi,
Thank you for posting in Windows Server Forum.
Have you check with other user account on that client machine?
Does ping response successfully to the server?
Firstly please try to run sfc /scannow, check performance for that system, check event viewer whether can find any particular error\event id. For more information you can refer below article.
Fix “The Windows Logon Process has Unexpectedly Terminated”
Hope it helps!
Thanks.

Problem downloading webutil DLLs to the client

Hi all,
when a PC has never used the application it will be missing the DLLs for use with webutil
(d2kwut60.dll, jacob.dll, JNIsharedstubs.dll)
our initial screen uses WebUtil and so these 3 files are downloaded as expected
now we start another form (our main form remains open)
then he tries to download again
but that only works for jacob.dll, the other 2 DLLs give this error: WUC-19 : .. cannot write to ... <name of DLL>
...DLL is not downloaded
What he says is true, we can not delete this DLL with windows explorer, file is locked by java
c:\Documents and Settings\MEAAI33\ webutil.WP0606.waak11.properties
contains the following:
# WebUtil File Properties
# Fri April 27 2012 2:37:19 p.m. EDT
syslib.jacob.dll = 1.10
only solution is to manually add remaining 2 DLLs in this file, which really is not an option as we have over 500 PCs
how to fix this ?

Hello,
The <FORMS_HOME>/server/webutil.cfg is located on the Application Server, so that you have nothing to download manually on the clients.
FYI, here is what I have in mine (Forms 10.1.2.0):
# Change size and version if necessary, like when upgrading the library.
# Normally this would not be required since most of these libraries come with
# install itself.
install.syslib.0.7.1=jacob.dll|94208|1.0|true
install.syslib.0.9.1=JNIsharedstubs.dll|65582|1.0|true
install.syslib.0.9.2=d2kwut60.dll|192512|1.0|true
