At this moment I get Marshal error 1336 "The access control list (ACL) structure is invalid." with the CreateNamedPipe function. All of the other functions seem to be completing sucesfully and are returning proper handles.[code]

C# - Add A Service To The Type Descriptor Context Of A Property Grid In .Net?
Apr 13, 2010I have an app that allows the user to choose an image, at design time, either as a straight image, or from an image list.
All cool so far, except that this is not happening from the visual studio property browser, its happening from a property grid that is a part of a type editor.
My problem is, both the image picker (actually resource picker), and the imagelist type converter rely on some design-time services to get the job done. In the case of imagelist, its the IReferenceService and in the case of the resource picker its a service called _DTE.
In the first instance of an edit from the visual studio property browser, I could get a reference to these services but (1) how can I add them to the type descriptor context of my property grid?
It would be better, for future proofing, if I could just copy a reference to all of the services in the type descriptor context. (2) Where does the property browser get these services from in the first place?
ETA: I still don't know how to do it, but I now know it is possible.
(1) Sub-class control and add a property whose type is an array of buttons.
(2) Add it to a form.
(3) Select the new control on the design service and edit the new property in the property browser.
(4) The collection editor dialog pops-up
(5) Add a button
(6) Edit image and image list - the type editor and type converter, respectively, behave as they should.
ETA2: Ok, I'm getting warm. It looks like you do it through the Site property of the property grid. I can create a new site, and pass it the type descriptor context I have a reference to and then it should have all the service. I'll give it a go ...

Substring Size - "Index And Length Must Refer To A Location Within The String. Parameter Name: Length"
Jul 21, 2010If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

Asp.net - Html To PDF And Security?
Dec 15, 2010We have a web app that is using forms security.One of the options includes the ability to print an html page to PDF. We're currently evaluating different products like PdfMetamorphosis, but I believe all of them will have this issue.The client makes a request for the pdf by clicking a link button. The code for the button instantiates the PDF builder and passes it a url to convert. However, the URL is behind our forms authentication. Which means that the resulting PDF is nothing but a login page.
Unfortunately, we need the user information in order to verify acccess to the printed page (among other reasons). Which means I can't just allow access to everyone to that folder.So I need one of three possible solutions.
1) I need a way to give the PdfMetamorphosis component the authorization ticket to pass on in it's request.
2) I need an html to pdf component that will do this.
3) Something else?
I don't think the first one is possible and I haven't been able to find a html to pdf component that takes this into consideration.
