How to use ReportViewer.PrintDialog() - ssrs-2008

I am trying to use ReportViewer1.PrintDialog() instead of ReportViewer1.Refreshreport()
I mean to take my report to printer, instead of viewing it.
But when I run the code, it generates error.
The error is
Operation is not valid due to the current state of the object.
Please advise what is the problem?
Thanks
Furqan

It might be because the report is already in the process of rendering when you call PrintDialog(). You have to wait for the rendering to complete in order to avoid this error. You can use the RenderComplete method to detect when the report is done rendering and it is safe to call PrintDialog().

Does ever calling `check()` on a capability panic?

According to the docs there is no reference of check panicking in any situation, but I would like to know if there is any edge case where this method could panic rather than returning false.
AFAICS, there are currently two cases where check() may fail:
The path leads to a cycle (see https://github.com/onflow/cadence/issues/2264)
Not sure: The code/type of the stored value is broken and cannot be loaded
Please feel free to open an issue in the Cadence repository if you think this should be changed, and especially why. Thanks!

Sudden too many errors: methods are undefined

My DES model was working well till I've added a new function (just like many others added before) and the model gave me all these error messages:
I wonder what do these messages mean and what made all of them appear suddenly. I was running the model just before it without any errors. Is there a way I could get my model back? :)
Thank you.
Edit 1:
Here is the newly created function: Newly created function
Given that I've ignored it, and made all the callings of it as comments, then the errors were still appearing. I've closed this model version and opened a backup then created the same function and the whole scenario happened again with the same 94 errors.
Is there something I need to change in the function itself?
The function checks the number of agents in certain parts of the model to stop delay blocks accordingly. That's done by adding variables that increment on exiting of agents and get the difference between them.
Typically this is caused by a syntax error in the new function that you created. See if you ignore this and then compile if it gets fixed.
Most of the time the compiler is smart enough to show you the error, but often if you replace a { with [ or you leave out a { the compiler get very confused and gives you 100s of errors.
If yous still cant find the issue maybe paste the code of your new function in the question.

Download stops due to missing data matlab

I am using websave function of MATLAB to download data from a website. The data is arranged by date. I have put the date in a loop to run the code for a certain period of time. However, on some dates, there is no data available. For those dates, the program halts and give 'internal error'.
I want to know how can I download data without interruptions even if there is missing data on some dates avoiding this internal error.
First of all, that sounds like a very poorly designed API if you're getting internal errors for an empty query result. Maybe there is a better way to make the call that you need? If you show some more code maybe we can help you.
That being said, you can use the try/catch construct to surround the call to websave, that way if it throws an error, it will not interrupt the flow of your program.
for k = date_range
try
websave(filename, url);
catch
% There was some error
disp('Skipping this one!')
end
end

Errordlg for any given Matlab error

I have a question about inner Matlab error management. Right now I have quite a large program with a lot of variables and functions that cumulated over my code writting and I'm 100 percent sure that I did not catch all the bugs and mistakes in the program and I don't want it to crash completely when is used by layman user. So, is there a way to display errordlg message and for example restart the program when there will be any given error directly by Matlab (for example when I forgot to declare a global variable etc.)?
Thanks for answers, Peter
Crashes are good, because they force users to report bugs.
If you don't want to go that route, Matlab provides try-catch: wrap your code in a try-catch block. If there is an error, you'll find yourself in the catch block where you can have Matlab send you an email with the error message, and restart the program if necessary.
You can use try/catch statements to respond to errors in your program. There's more information here.

Why my custom activity never returns?

I'm a newbie to WF and rather lost. Here's what I have so far:
I've created a workflow service app (xamlx), added needed variables
I've created a custom NativeActivity where I'm calling CreateBookmark from within Execute, which is between the Receive & Send activity for the service. (Ultimately this will actually do something besides creating the bookmark).
The bookmark gets created just fine, but after stepping out of the Execute method, nothing happens for one minute until the service times out, giving me that message "The request channel timed out while waiting for a reply after 00:00:59.9699970. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout." (I tried posting an image of the xamlx, but as a newbie it won't let me; suffice it to say I'm getting from my Receive, into my custom native activity, but never getting as far as the SendReply).
I assume I'm missing something rather fundatmental, but I can't see what. I've originally tried using NativeActivity<T> to return what I want, but that behaves the same.
Found out what I was doing wrong: needed to use overload of CreateBookmark that has BookmarkOptions parameter and set it to BookmarkOptions.NonBlocking.
Strangely, I did not find one example anywhere that mentioned this.
