  • Calling COM Library From XBAP

    - by Benny
    I am trying to call an old COM library from my XBAP and continue to receive the following exception: System.AccessViolationException was unhandled Message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I have tried adding the HKLM value for RunUnrestricted to no avail. I don't get anything else but this error when calling the library. Any ideas? (This library even works from a pure ASP.NET app)

  • Accessing underlying managed object through a COM interface

    - by mfeingold
    I have a third party assembly with a public abstract class implementing a certain COM interface. Something to the effect of [ComVisible(true)] public abstract class SomeClass: ISomeInterface { .... public void Method1() {...} } The actual object is an internal object extending the SomeClass and is instantiated by the third party code Is there a way to access public methods of this class if all I have is the CCW to the ISomeInterface?

    - by Tao
    I have a Delphi COM Add-in for Outlook (2000-2007) and am trying to find a way to register an event when an MailItem in Outlook is marked as read. I want to add an additional property to the item as/just after it is marked as read. Does anyone have any idea how to do this using the Outlook Object Model? I am also using Add-In-Express components to help get to additional properties events.

  • Registering a COM control during installation

    - by Curtis
    One of our applications needs to register a COM control during installation. If a newer version of that control is already registered, we don't want to overwrite it with the older. What are the Windows MSI install conditions I would user to control this? Or is there some other 'best-practice' method I'm not aware of? Thanks

  • Native.* assemblyIdentity with Registration-free com

    - by moogs
    I set Isolated=true to some COM library that I need to use registration free. Visual studio now created Native.* manifest files for each of my assemblies: Why "Native"? Can I change this? Can someone point me to info I can read? (googling native / assembly / manifest is yield a lot of non-related info ) Is there a way I can embed these manifest files into the assembly DLL? Thanks!

  • WCF wrapper COM object

    - by LarryR
    I have a third party COM component (they don't offer a .Net assy), that has the additional feature that it only works under x86 compile. I am trying to wrap this in a WCF service, but if I select x86, the service won't start (System.BadImageFormatException). Any workarounds for this ? Thanks Larry

  • COM(C++) Programming Tutorials

    - by Deep-B
    Hey guys, I was wondering if there're any good sites that deal with learning C++/COM from the ground up? Looking for something like a crash course (two weeks, and not being hypothetical here). Assume knowledge in standard C/C++, or at least not a complete dummy.

  • Copy protection and licensing tools.

    - by Skittles
    I'm new to stackoverflow.com after hearing about it from Jon Skeet on DotNetRocks.This seems like the perfect place to ask this question. I am in the middle of trying to find a 3rd party Copy protection and licensing tool. The company that I work with have 4 products that need to be protected. We want to supply a Trail license (with extensions). A single user license and a floating license (where the client purchases a number to run over a network). We also want to be able to supply both the Single and Floating license as a subscription license. I have trialled DeployLX and although it seems to give everything that we need, and they are quick to answer emails, their documentation is truly awful with NO examples of how to achieve results. Has anyone any experience with DeployLX and if so, would you recommend it? Could you point me in the direction to find some real help on it? Finally, would anyone have any recommendations of a 3rd party licensing tool to use for very quick development. Thank you so much,

  • Copy Selective Data from Database to Invoice, Based on Certain Criteria

    - by Scott
    For starters, here is an example of a microsoft excel database I am working with: Month/Address/Name/Description/Amount January/123 Street/Fred/Painting/100 January/456 Avenue/Scott/Flooring/400 January/789 Road/Scott/Plumbing/100 February/123 Street/Fred/Flooring/600 February/246 Lane/Fred/Electrical/300 March/789 Road/Scott/Drywall/150 What I want to be able to do is selectively copy info from this databse to invoices (also excel). The invoice has three columns: Address/Description/Amount. I want to be able to automatically fill the invoices in as the database is filled in (either automatically, or if I have to actually manually run the macro to do it, that might be fine). Each name (Scott, Fred, etc.) will have their own set of 12 invoices for the year. So, e.g., I want to be able to produce a January invoice for all work done for Scott in January, showing the address, the description and the amount, line by line. So every time work on Scott's address(es) is done, the database is filled in, and i want it to "send" that information to the invoice on the next available line, filling in only the Address/Description/Amount columns from the database. Fred's invoice should fill in as any work is done on Fred's addresses. And once the month changes, the next invoice should start filling in. So first I need to filter the data by the month and the name (and there is actually one more column to filter by, but let's keep this example simpler). Then I need to list the remaining data on the invoice, but only certain cells from the rows that are now left. Help anyone?

  • Open an excel file using COM and save it as .xml file

    - by chupinette
    Hi. Im trying the following code: <?php $workbook = "D:\b2\\test.XLS"; $sheet = "Sheet1"; #Instantiate the spreadsheet component. $ex = new COM("Excel.sheet") or Die ("Did not connect"); #Get the application name and version print "Application name:{$ex->Application->value}<BR>" ; print "Loaded version: {$ex->Application->version}<BR>"; #Open the workbook that we want to use. $wkb = $ex->application->Workbooks->Open($workbook) or Die ("Did not open"); #Create a copy of the workbook, so the original workbook will be preserved. $ex->Application->ActiveWorkbook->SaveAs("D:\b2\Ourtest.xml"); #$ex->Application->Visible = 1; #Uncomment to make Excel visible. #Optionally, save the modified workbook $ex->Application->ActiveWorkbook->SaveAs("D:\Ourtest.xml"); #Close all workbooks without questioning $ex->application->ActiveWorkbook->Close("False"); unset ($ex); ?> This actually works and creates the Ourtest.xml file. But im getting characters like: ÐÏࡱá þÿ þÿÿÿ I have tried with SaveAs("D:\Ourtest.pdf") and it says the file has been corrupted or incorrectly decoded. Can anyone help me please?Thanks

  • Wysiwyg with image copy/paste

    - by jW
    First, I understand that an image cannot be "copied" from a local machine into a website. I understand that it must be uploaded. I am a web programmer, and am familiar with common web wysiwyg tools such as TinyMCE and FCKEditor. My question is if there exists a program or web module or something of the sort that works will perform an automatic upload of images for a wysiwyg. I have a client that is constantly complaining about not being able to copy/paste documents with images from MS Word into a wysiwyg to create content on their website. I have looked into TX Text Control (http://labs.textcontrol.com/) and was looking into a possibly flash wysiwyg that could upload the file automatically behind the scenes. I don't know if this exists, and google did not much help me in my search, so I thought I would ask other coders. I am open to any sort of server technology, or browser requirements. I am looking for some browser based tool instead of an application tool such as Dreamweaver or otherwise. If no good solution to the problem exists, I am willing to accept that at this point. Note: This was a request from a client, and to me it seemed rather unreasonable. I decided to gather community advice instead of just tell the client 'No' and the options here have been extremely helpful and informative in presenting possible solutions.

  • Fork or copy a users browser session in IE

    - by jmoeller
    Is it possible to fork a users session (or do something similar) in a Internet Explorer plugin? I want to process the page the user is on when they click a button in the toolbar. To avoid interrupting the users browsing, I'd like to "copy" everything so I can parse and process the page in the background. The processing can involve things such as loading the content of the result links on a Google search, if that's where the button was clicked. So - what I basically want is to imitate "Ctrl+N" but hide the window from the user, so they won't be interrupted. As you can see, if you fill out and submit the form on http://www.snee.com/xml/crud/posttest.html and press "Ctrl+N", everything posted will still appear in the new window, but it won't post the data twice. I was thinking of somehow copying the IWebBrowser2, but: I'm not sure if that's possible (I haven't been able to find any information on MSDN) I don't know if it copies the sessions as well. Creating a new instance of the IWebBrowser2 and simply navigating to the current URL isn't a valid solution as POST-variables of course doesn't get carried over.
