View 10 RepliesI have a .NET application that interops with a VB6 COM DLL. After installing the application on a Vista machine, I try to execute the code that consumes that COM component and I get an error attempting to read or write protected memory. The system's DEP is set to only essential programs and services, but apparently that automatically applies to .NET applications. When I tried to exclude the application from DEP, it said that DEP must be on for this program (could not be turned off). I had to use the bcedit.exe program to manually turn DEP off system wide and then reboot. After that, the application ran without a hitch, but this is not the route we want to go for our users. Are there any solutions/recommendations for this? It seems as though DEP has been more of a headache than not.
View 5 RepliesI'll like to know something about the option "Register for COM interop" into the project Compile screen from a project.
Is this check box do the same job as RegAsm.exe?
I'm asking this because since I've enabled this option the compilation of my project take 30-45 seconds instead for 2-3 seconds. And I've really need the .tlb file.
If the RegAsm program do the same job, then I will only rebuild my .tlb when needed instead of every compile.
I have an application I am converting over from vb6 to vb.net 2.0/3.5. Using Subsonic 2.2 and the vb.net Interop Toolkit 2005. Cannot seem to get the .net form using subsonic to work inside the interop environment.It keeps saying it cannot find the subsonic service provider in the app.config. But I know it is there. Has anyone used these two toolkits together successfully? Will subsonic even work inside the interop environment in that way?
View 1 RepliesI am working on a class that generates a report in Excel (any version).I need to perform a bit of ad-hoc labelling on a chart, for which I have created a textbox (i.e. Excel drawing object).I've managed to get as far as creating the textbox and setting it's text using Shape.TextFrame.Characters.Text. Ideally, I'd like to set the font characteristics as well, but I can't see how to do this. I can't seem to find much info about this anywhere, so hopefully someone's dealt with this before and can give me a few pointers.

View 1 RepliesI have a VB.net 2005 app using the Microsoft.Office.Interop.Excel.dll version 11, deployed on a number of XP machines with Office 2003 installed. On one and only one machine I get the following error:Error -2147467261 Attempted to read or write protected memory. This is often an indication that other memory is corrupt.The line which triggers the error is:

This should save an Excel file in a folder on the desktop. I can save a file from Excel in that folder, and create a new Excel file in it from the right-click option. The app is working correctly on the development machine and at least 8 other XP boxes on site.All Office and dotNet 2 updates have been applied.Office and dotNet have been uninstalled and reinstalled to no effect.

My Problem: I am using Matlab COM Automation Server to call and execute matlab .m files from a VB.Net plugin for a CAD program called Rhino 3D. The code works flawlessly when set up as a simple Windows Application in Visual Studio, but when I insert it (and make the requisite reference) into my .Net plugin and test it in the CAD program I get the following error: "Could not load file or assembly 'Interop.MLApp, Version 1.0.0.0, culture=neutral, PublicKeyToken=null' or one of its dependencies. the system cannot find the file specified."
What I've Tried: I am baffled as to why this occurs, but I was able to contact the CAD program's technical support staff and they suggested that it has something to do with their DotNet SDK having trouble with references that are located far outside the CAD program directory. They didn't have any solutions so I tried playing around with copylocal and this made no difference. I tried using other COM libraries and the Open Office automation server works fine, although uses url's instead of requiring a reference. I also tested Excel, which does require a reference, and it returned the error: "retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154." This may or may not be related to the issue with the Matlab COM reference, but I thought was worthwhile to share. Perhaps is there another way to reference Interop.MLApp?

View 12 Repliesi have a MDI Parent. As you know a MDI parent can have scroll bars. I want to make customized scroll bars. Meaning instead of windows default scroll bars i want just to images / buttons (arrows (up/down)) that when clicked will scroll up and down, and then others for left and right...
How do i do this? I dont want windows default scroll bars to appear.. i know can disable them but then is there a property / method to scroll in a direction, let my code do the work.... i would also then want it so as you scroll my custom scroll buttons wont go away, as you scroll they should stay in the same spot.. i think i can do that by a panel and docking, so that isnt important.
