Open a dialog from a Sitecore uiUpload Pipeline process - dialog

I'm currently trying to show a SheerResponse.YesNoCancel() dialog within the Save uiUpload pipeline process from Sitecore. The problem appears when I do that call and it throws a NullException. I thought it was weird so I started copying the code from Sitecore's DLL and adding it to my solution. After that, I found that if the property OutputEnable is false it returns a ClientCommand that is NULL and when it tries to add a control to it, the Exception appears. So Fixing that I was able to finish the execution of that method. Anyway I still can't show the dialog. So the question is: Can I show a Dialog from a Sitecore uiUpload pipeline?

Have you tried using Sitecore.Context.ClientPage.ClientResponse.YesNoCancel(), i did something similar to what you are trying to do, but i used Alert(), worked fine for me.
Update: Actually inside uiUpload pipeline you can't call this method, however what you can do is use HttpContext.Current.Response.Write("<html><head><script type=\"text/Javascript\">[Your Java Script</script></head></html>"), you will need to abort the pipeline after this args.AbortPipeline();, not sure if this will help your case or not

No you cannot. From http://sdn.sitecore.net/Articles/Media/Prevent%20Files%20from%20Uploading.aspx:
The uiUpload pipeline is run not as part of the Sheer event, but as part of the form loading process in response to a post back. This is because the uploaded files are only available during the "real" post back, and not during a Sheer UI event. In this sense, the uiUpload pipeline has not been designed to provide UI.
That page was written for v5.1 and 5.2, but I'm pretty sure it still applies. The page claims that you can emit javascript to the page like Ahmed suggested, but it didn't work when I tried it.

Blue Prism: Object not found when ran using Control Center, but runs without issue through Process Studio

During my process there is a drop-down html element that I have spied and set correctly. I run through the Object and Process studio without any issues. Once the same process is ran through the Control Room the element throws and error that it cannot be found.
I have tried multiple different configurations without any luck and the element is still found without issue when ran manually. I even checked by signing into the VM having it error and on the second retry had the VM up; at this stage the element was found without issue. It seems to only be when the bot is running and the screen is not up. No other elements give this issue and the next step is the same dropdown, but for a stop time not start.
Any help would be appreciated!
I have added pics of the STARTSPIED - START and ENDSPIED - END spied configs,the Navigation Stage, and the process correctly running in the Object Studio OB Studio correct.
Thank you!
For the person who down-voted this item...Configs here are my two days of config changes and research that I tried on my own before asking for help. This is my 5th automation that I have put into deployment without help, so thank you for down-voting someone trying to get help where they are stuck.
Your problem is most likely connected with the fact that processes run in the control room are executed much faster than in studio and your webpage might not be loaded on time (that would explain why it works after retry).
Best practice approach would be to add a dynamic wait stage after attach and use “Parent Document Loaded” option on the element you want to interact with. It will wait for the page to be loaded and then check exist for the element. I would also suggest splitting your action into two, first to set start date and second for end date.

Why am I getting a DDE error when opening a file in Explorer that associated with our application?

Our legacy MDI desktop application uses the /dde switch in the association. When opening a file associated with it, and the application has not yet started up, Explorer pops up the following error:
There was a problem sending the command to the program.
The registry looks something like this:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document]
#="App File"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\DefaultIcon]
#="d:\\Program Files (x86)\\MyApp\\version\\app.exe,1"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\open]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\open\command]
#="\"C:\\Program Files\\App\\app.exe\" /dde"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\open\ddeexec]
#="[open(\"%1\")]"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\print]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\print\command]
#="C:\\Program Files\\App\\app.exe /dde"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\print\ddeexec]
#="[print(\"%1\")]"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\printto]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\printto\command]
#="C:\\Program Files\\App\\app.exe /dde"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\App.Document\shell\printto\ddeexec]
#="[printto(\"%1\",\"%2\",\"%3\",\"%4\")]"
Just to be clear, I just took these entries from the registry. I'm not well versed in what they do, but I can hazard a guess that they link the verbs to actions by way of the DDE interface.
Note that if the application has already started up, the document opens up fine in that instance. This is only an issue if the application hasn't started up and must execute a new instance of the application.
So, what is happening is that the associated file is opened through Explorer by double clicking on it, and the associated application is executed. Explorer would then pop up that message and our application would do nothing. Double clicking on the file a second time would then open the document.
We've had this issue previously, but we just decided to ignore it for a few years as no one really knew what it was and we had other priorities at the time. Our workaround was to tell the user to change the /dde to "%1". Yeah, lame, but it worked well enough. One issue with doing that though, was that it would execute a new instance of the application, regardless if the application was already running or not.
Anyways, this issue is now starting to become an actual problem and needs to be fixed. One of our developers is saying that the DDE system is antiquated and we should try writing a COM component that will redirect to our application like Visual Studio does as debugging this issue could take a while. I've not verified that yet, nor researched how much effort that would be. However, either may be resource intensive, either on the debugging or the research side, so I'm trying to do some preliminary research to see what I can dig up and determine which is the better approach.
Stepping in the code, I was able to determine that it gets to a ::SetWindowPlacement() call and stepping over that will cause the error message box to pop up (if Explorer hasn't timed out first). As it is a WINAPI, I cannot step into that function to see what it is doing.
The application is written mostly in VC/VC++ using MFC/API and other libraries.
So my question is, does anyone know why this is happening and how it can be fixed?
Edit
Some additional information:
I was able to intercept all of the SendMessage()/PostMessage()/DispatchMessage() function calls non-destructively, which will log all of the messages. This was achieved by using MS Detours 3.0.
What I am seeing is that there are 4 SendMessage calls with a WM_COPYDATA message which appears to be coming out of shell32.dll. However, it doesn't appear to be the messages that are at fault though.
Putting a __debugbreak() when it detects the WM_COPYDATA message results in no error until a few steps beyond. How far depends on if I step or if I put a breakpoint and run the code to somewhere beyond where I thought I was getting the error. Using DebugBreak() seems to slow down the debugger to the point where I can't step without the error showing up.
What I can't understand is that there doesn't appear to be any rhyme or reason as to what is triggering the error message to pop up. I doesn't appear to be a timeout as the timeout appears to be long until I start stepping in the code, and sometimes no messages are being Sent/Posted by the code. So there's no WM_DDE_ACK (or any message for that matter) being sent back to the Explorer window that has initiated this. This is very frustrating.
To further complicate things, if I use the intrinsic __debugbreak() call and I have a breakpoint somewhere else in the code, it sometimes can stop at that breakpoint rather than stopping at the __debugbreak(). And sometimes, when I run the code immediately when I get control of the debugger, it will sometimes result in a second break, as if it hit another __debugbreak(). What's that all about? Inconsistent debugging is certainly making this issue even harder to track down. >:(
This DDE stuff is still the in use for MDI interfaces. So if one EXE opens different files.
If you can launch you application multiple times and this is OK, for the customer, switching the entries in the registry to the normal place holders from the SDI is OK too.
Usually this message is shown from the explorer, if the EXE doesn't get ready in a specific time to accept the DDE commands.
So the main question for you is: What is changed or so slow in the application that the DDE messages are not retrieved.
On case would be if it takes a real long time until the message loop starts. A running message loop for the main window is required for DDE support.
SetWindowPos istself will not be the problem, but it might cause hundreds of messages (WM_SIZE, ...) to be fired to your application, and every handler in your application here might be the problem.
Just place a little timer inside the application in front of the SetWindowPos and check how long it takes to return...
Check how long the app takes, until InitInstance is exited with TRUE. After InitInstance exits CWinApp::Run starts and the message loop starts.
I've run into the same problem.
My solution was to add the ../ddeexec/* section in the registry on application startup and then remove them on application exit.
Not a very nice solution but it is easy to do, and it works.

getDocument() from a XSPDocument is null randomly

In a production application that I have developed sometimes I get an error saying .getDocument() is null. I have added checks in my code that traps an error if this happens. And the strange thing is that the XSPDocument seams to be OK.
Any other ideas how to debug the cause of this?
========================================================
Edit
The lower parts of the application is a simple database, create an assignment it gets status new
change the status to ongoing thru a button. Add information in text, date and numberfields, no Richtext, no attachments.
The user can switch to another xpage to send this document is an pdf attachment in an email.
The user can save the document as a draft
When they are done the click on an approve button and this button will set the status to approved. Save the document and send it as an pdf to an email adress
The problem ocurrs both on the Save button and on the approve button.
.getDocument from the xsp document is null the xspdocument.getNoteID return an ID
I can do replaceitemvalue on the xsp document.
It never happens on new documents only existing what I have seen
It feels like the comment from David that the backend doc is dropped/recycled
we experienced the same getDocument() problem recently. Finally we found a root cause: two different XPages were loaded simultaneously via iFrames. One of those XPages produced run-time error randomly, in 25% of cases. A sort of conflict in JSF model in context of single session.
solution: viewState="nostate"
not sure if it helps in your case, but this option resolved a lot of problems in our applications. It was introduced in 8.5.3. And it should be especially useful for so called XAgents.
Hard to give a hint without knowing more about everything else, but I remember having seen this as well. Just a few ideas:
Is XSPDocument.getNoteID() pointing to a valid Document if this happens?
Is it maybe pointing to a different doc than what you expected?
Could there be some kind of dynamic change of datasources going on?
Maybe some kind of timeout so that the server all of a sudden forgot who you are (in rare cases this happens to me)?
Lothar/edcom
It would be helpful to have a few more details. I assume that the document has previously been saved and it's not a new note?
You're not trying to put the actual document object inside a scoped variable are you? That would be bad as that would be pretty toxic. Without knowing more I would think this could be the case. The backend document has been garbage collected.

How to write text values in masked field?

i need some help related to masked field in web form. Syntax of phone field is (___)___-_____, if i execute this code in ruby shell
browser.text_field(:id => 'txtphone').set '7893457889'
... nothing has been added in the phone field.
then i find this solution in one blog, someone said first unmask this field using this code.
browser.text_field(:id,'txtphone').fire_event("unmask")
then write the above code again.
browser.text_field(:id => 'txtphone').set '7893457889'
but still nothing has happened. kindly help me out...am i doing right or still there is a mistake.
If you could provide some sample of the page HTML it will be easier to give you an answer more likely to work.
Given what you have provided us to work from, we have to go with the normal way that such masked input fields typically work and go from there. Usually pages with this kind of thing are calling a javascript function which is triggered by a specific event. Most often this is an event such as onchange but it may be something like keypress or any other even that happens when a normal user types or pasts text into the cell.
You likely need to experiment with using the '.fire_event' method to fire the proper javascript event, or if that fails entirely making a direct call to execute the proper script
When doing this do not confuse the name of a script such as 'applymask' or somesuch with the javascript event which causes that script to be invoked.
The answers to this question How to find out which JavaScript events fired? include some good information on how to use firebug or the chrome developer tools to figure out what events are being fired when you interact with an object on the browser screen.
Update: instead of responding here to indicate if this answer was of any use the OP reposted their question here Masked Text Box issue and by digging around on the vendor's demo site (since that time he actually had posted some of the HTML when we asked for it) I was able to find a solution using watir-webdriver that worked for him.

Information Management Policy in SharePoint

An obscure puzzle, but it's driving me absolutely nuts:
I'm creating a custom Information Management Policy in MOSS. I've implemented IPolicyFeature, and my policy feature happily registers itself by configuring a new SPItemEventReceiver. All new items in my library fire the events as they should, and it all works fine.
IPolicyFeature also has a method ProcessListItem, which is supposed to retroactively apply the policy to items that were already in the library (at least, it's supposed to do that for as long as it keeps returning true). Except it doesn't. It only applies the policy to the first item in the library, and I have absolutely no idea why.
It doesn't seem to be throwing an exception, and it really does return true from processing that first item, and I can't think what else to look at. Anyone?
Edit: Cory's answer, below, set me on the right track. Something else was indeed failing -- I didn't find out what, since my windbg-fu isn't what it should be, but I suspect it was something like "modifying a collection while it's being iterated over". My code was modifying the SPListItem that's passed into ProcessListItem, and then calling SystemUpdate on it; as soon as I changed the code so that it created its own variable (pointing at the exact same SPListItem) and used that, the problem went away...
There's only a couple of things I can think of to try. First, are you developing on the box where you might be able to use Visual Studio to debug? So just stepping through it.
Assuming that's not the case - what I'd do is fire up WinDBG and attach it to the process just before I registered the policy. Turn on first chance exceptions so that it breaks whenever they occur. you can do that by issuing the command "sxe clr" once it is broken in. Here's a little more info about WinDBG:
http://blogs.msdn.com/tess/archive/2008/06/05/setting-net-breakpoints-in-windbg-for-applications-that-crash-on-startup.aspx
What I'd do is then watch for First Chance exceptions to be thrown, and do a !PrintException to see what is going on. My guess is that there is an exception being thrown somewhere that is causing the app to stop processing the other items.
What does the logic look like for your ProcessListItem? Have you tried just doing a return true to make sure it works?
Some nice ideas there, thanks. The Visual Studio debugger wasn't showing an exception (and I've wrapped everything in try/catch blocks just in case), but I hadn't thought of trying Windbg...
