Using NI controls in a DLL running from a non-MFC application

Hello,
I am developing a DLL library for use with a non-MFC third party application. The DLL I am currently working on displays a MFC dialog, and works fine from the third party app, as long as I don't add any NI Measurement Studio controls. When I add in a CNiGraph control, the dialog window can't be created.
Does anyone have any suggestoins about this?
Thanks,
-Robert

Hello Robert,
The setup that you have here sounds perfectly valid and should have no errors. The firts thing to check is that you have enabled support for ActiveX in your MFC DLL. When you run the new project wizard one of the options is to enable ActiveX this adds some initialization code to enable the ActiveX container.
You can test this by adding any other ActiveX control to your dll and give it a try. If you get the same error then most likely the ActiveX container is not properly initilized.
Let me know how this goes.

Despite my best efforts, I am unable to remove iTunes 11.1.4 from my PC, this being made necessary because the original installation had a flaw and did not load properly. Effor to use the control panel, deleting dll. files, etc. all failed. iTune out??

Despite my best efforts, I am unable to remove iTunes 11.1.4 from my PC, this being made necessary because the original installation had a flaw and did not load properly. Effor to use the control panel, deleting dll. files, etc. all failed. And, of course, on startup, a window opens with the error and tells me find QTMovie.dll and delete it because this may be the source of the hangup. Also, in trying to delete iTunes, I get the additional message that I must get approval from the System Administrator to take this action. I am the System Administrator.
Any ideas would be welcomed.
Thank you.

Using CW UserInterface Control in non MFC application.

Is it possible to use CW++ controls in non MFC application ?
I need to display a graph in a dialog based application that does not
use MFC (written with all windows procedures).
Dimitri

Dmitri,
This is not directly supported in CW++. CNiGraph derives from CNiControl,
which derives from MFC's CWnd.
The controls are ActiveX controls, however, so it should be possible to use
it in a non-MFC application just as you would any other application. The
downside to this is that you will have to use the automation data types such
as SAFEARRAY and VARIANT instead of the C++ data types such as CNiVector.

Retrieve data from a non-peoplesoft application using HTTP Get

I need to retrieve data from a non-peoplesoft application. They want us to submit a HTTP GET request to their URL with a series of parameters. I am thinking about using HTTP Targert connector to accomplish this. Does anyone have sample peoplecode?
Currently we are on 8.51.10 Tools...
If there is any better way .. please let me know ..

I have used HTTP Get to get XML file from a government sanction list by hitting URL http://www.treasury.gov/ofac/downloads/sdn.xml
There is a delivered PS program that does that for vendor sanctions. I had to get the online setup correctly by creating a new custom Node with HTTP Target Connector. The program name is BSP_IMPORT. The below code is responsible for the calling the node and retrieving the data. Play around with the code below see if you can get it to meet your needs.
BSP_IMPORT_AET.BANKNODE.Value is just the custom external code that I created.
PMT_FLAT_FILE_INBOUND message is just a none rowset based message to use the web service call.
Local TR:FileUtilities:FTP &oFTPUtil = create TR:FileUtilities:FTP();
+/* HTTP */+
+/*******************************************************************************/+
Local Message &msgHTTP;
Local Message &msgResult;
+&msgHTTP = CreateMessage(Message.PMT_FLAT_FILE_INBOUND);+
+&oFTPUtil.PopulateFTPGetIBInfo(&msgHTTP, BSP_IMPORT_AET.BANKNODE.Value);+
+&msgResult = %IntBroker.ConnectorRequest(&msgHTTP);+
+/* check to see if the file is wrapped */+
+&strAllLines = &msgResult.GenXMLString();+
+&strAllLines = Substitute(&strAllLines, Char(26), " "); /* Added this line to remove invalid characters */+

Re: [iPlanet-JATO] from a non jato application to jato application

Without getting into the details, the session id is passed around in a
cookie, but once you leave your JATO app "sandbox", you no longer have
access to the same session. This is not a JATO limitation, but a J2EE
spec constraint. The war file creates a Servlet Context. Other servlet
contexts have separate session sandboxes. If you deployed all your apps
within the same war file, your sessions would be mutually accessible.
or
You could do something like use a Session EJB and pass its reference
between apps I suppose.
Also, see JATO Tip #0011 for forwarding to a "non-JATO" target.
Hopefully, my reply will open up a conversation for more solutions,
ideas, if what I have proposed is insufficient.

Invoking SOLMAN WS from a NON-SAP application

Hello All,
Has any one accessed the SAP SolMan web services from a non-sap application ? For my project, I need to talk to solman through its exposed operations as defined in the WSDL file
http://mycompany.com:8003/sap/bc/srt/rfc/sap/ict_service_desk_api?wsdl
When I invoke this WS through eclipse, after taking in the UID & PWD, it is returning appropriate values for:
RequestSystemGuid
RequestGuid
Getpossiblevalues
It fails for all other operations. For e.g. ListUnclosedIncidents returns and error called :
ErrorCode (unsignedByte): 13
Similary for the operation 'ReadCompleteIncident'
What is it that needs to be done to surmount this error ? Any pointers, suggestions ?
Thanks
Karthik

Hi, did you accomplish to solve your problem using the list unclosed incidents operation?

Open Apex page from a non-apex application

Hello,
I'm calling an Apex page from another (non Apex) application. The way it works is that you click on a map and a browser window is opened with a Apex data entry form. This way you can edit information about the object you clicked on in the map.
I got this working but what I'm trying to avoid is that you have to enter your logon credentials every time. I can't provide a session ID in the URL from the other application.
Is this possible at all?
Rene

Hi Scott,
I tried following your example here:
http://apex.oracle.com/pls/otn/f?p=9947:1
Page 1 and 2 are normal, but rather empty, pages. Page 3 is the public page with the redirect proces.
First login (demo/demo_12) and notice the session ID.
Then try to redirect to page 2 through page 3
http://apex.oracle.com/pls/otn/f?p=9947:3::2
You get the login page again with a new Session ID.
Once you logon you get redirected to page 2 and have joined the previous session.
Is this the expected behaviour of your example? I was trying to get rid of the login screen the second time. Maybe I'm doing something wrong?
thanks Rene

Submit a webdynpro IView from a non-Portal application

Hi,
i have create a WebDynpro application. This application shows in a table a list of '. This reports are IView for Bex Web Application in a SAP portal. For navigation to this BW IView the WebDynpro application must be also embedded in a WD iView.
The problem is:
This WD IView will be requested by a non-sap/portal application with dynamic parameters and also with the POST method.
In the WD application i have implemented the parameter request with following code:
int i = 1;
String name = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("var_name_" + i);
If the non-portal application submit the WD application directly -> the parameters are available.
But when the non-portal application submit the WD IView, then the Parameters are 'null'.
Thank you for quick response
Anne

Hi,
yes I'm use the statement to submit the iView:
<form action="http://server:50000/irj/servlet/prt/portal/prteventname/Navigate/prtroot/pcd!3aportal_content!2fevery_user!2fgeneral!2fdefaultDesktop!2fframeworkPages!2fframeworkpage!2fcom.sap.portal.innerpage!2fcom.sap.portal.contentarea?NavigationTarget=ROLES%3A%2F%2Fportal_content%2Fcom.kwl.kwl-01.KWL-01%2Fcom.kwl.kwl-01-iviews.KWL-01-Iviews%2Fcom.kwl.WEB_DP%2Fcom.kwl.IW_GISBW&DynamicParameter="
method="post">
var_name_1<input name="var_name_1" type="text" value="ZHAMFSB"><br>
var_value_ext_1<input name="var_value_ext_1" type="text" value="129191"><br>
var_name_2<input name="var_name_2" type="text" value="ZHAMFSB"><br>
var_value_ext_2<input name="var_value_ext_2" type="text" value="129761">
<input type="submit" value=" Senden ">
In this case the DynamicParameter will be send by GET.
But i want use the POST Method.
I get the parameters in both cases not in my WD application.
What is the problem?
Thank you
Anne

I have programmed a visual basic application using activex controls. WHen I run this application through internet, it appears a message box indicating that the measurement studio is a demo, but I have the correct license. What can I do?

I run the application in a computer without measurement studio because my application is stored in a web server and I access to the application downloading it from a web page of that server.

Have you included the lpk file with your control? I've attached the tool you'll need and here is a nice link that goes thru it step by step.
Hope this helps

COM Exception while using CWGraph controls

Hi,
I am trying to use activeX controls(AxInterop.CWUIControlsLib.dll, AxInterop.CW3DGraphLib.dll) provided by NI in my sample application (wriiten in C#) but I am receiving COM exceptions after the activeX controls gets instantiated.
Has anyone encountered such a problem before. Any help will be highly appreciated

I am trying to migrate a vb6.0 project which is using a CWGraph control to C# application. The installation of the vb6.0 application also adds cw3dgrph.ocx ,cw3dgrph.ocx and cwanalysis.ocx controls in System32 folder and I am referencing the same control in the C# application and trying to access the CWGraph control (C# itself creates the wrapper for this ActiveX controls:AxInterop.CW3DGraphLib,AxInterop.CWUIControlsLib,etc).
When I enable the CLRExceptions from the Debug menu in Visual studio and run the code , an unhandled exception of type COMException occurs without any description about th exception(it displays Unknown Error). everything runs fine if I disable the CLRException from debug menu.

How to use gApp.MenuItemExecute("BatchEdit") then programmatically Run Sequence

I am attempting to use the Acrobat 9 SDK - IAC API from a VB.NET application to select and run a batch sequence.
It is running on Windows XP SP3 with Acrobat 9.1.
So far my code :-
Dim gApp As Acrobat.CAcroApp
If Not gApp.MenuItemExecute("BatchEdit") Then
If Not gApp.MenuItemExecute("BatchEdit") Then
MsgBox("Batch Sequences menu was not found.")
End
This successfully displays the Batch Sequence dialog.
How do I now select the desired sequence and then Run Sequence and execute the resulting dialog?

Thanks for your prompt reply.
If I can't run sequences can I instead run other meni items?
Can I run MenuItemExecute on other menus and then control the resulting dialog e.g. Optimize Scanned PDF or PDF Optimizer or Reduce File Size.
If I can't control these dialogs, what is the point of the MenuItemExecute command?

How to I burn to a DVD my project edited on my new imac
If you are still within your 15 day return period. Call Apple they will sent out iDVD at no charge. (There are no realistic substitutes.)
Nicely explain that you may return the computer without iDVD. You MUST speak to a senior advisor to get a free copy. The first tier people cannot do it.
408-996-1010
800-692-7753
If that doesn't work you can purchase iLife 11 (includes iDVD) on disk.
IDVD is a wonderful piece of software and well worth the low cost of $40.
