  • Can a program that controls IE detect if a HTTP 30x code is encountered?

    - by hillu
    I am trying to control an InternetExplorer.Application via the COM interface, using Perl, Win32::OLE, and information from MSDN. My goal is to get as good an idea as possible about what IE is doing. (Related to this question.) IE uses events to notify my program when it has finished various stages of processing a certain URL (NavigateComplete2, DownloadComplete DocumentComplete). It can also tell my program about various errors it encounters (NavigateError2). I consider that part of my problem solved well enough. I would also like to be able to reliably detect if IE is redirected by the server. Primarily, I'm concerned about HTTP 30x status codes. Is there a way to do this, either with COM automation or via another route?

  • Calling a running C# application from VBA

    - by Robert
    I have some VBA code that needs to talk to a running c# application. For what it's worth, the c# application runs as a service, and exposes an interface via .net remoting. I posted a question regarding a specific problem I'm having already (http://stackoverflow.com/questions/2556163/from-vb6-to-net-via-com-and-remoting-what-a-mess) but I think I may have my structure all wrong... So I'm taking a step back - what's the best way to go about doing this? One thing that's worth taking into account is that I want to call into the running application - not just call a precompiled DLL...

  • Virtualized Screen Resolution

    - by Jim R
    I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04. The problem is that I would like to use a larger size display that is configured by default. Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080. This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation. The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file. I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily. Is what I want to do possible? If so, how do I accomplish it?

  • How can I connect integrated webcam with virtualbox

    - by Mike Stumpf
    I am trying to use a Windows XP VM for VirtualBox on my Windows 8.1 laptop. I have tried the usual attaching USB device but I get an error saying "USB device is busy with previous request". My webcam is not active in any applications and this happens after a clean reboot of the host, the guest, and VirtualBox.

  • C#/Resharper 5 structural search, detect and warn if any non-virtual public methods on classes with

    - by chillitom
    Hi All, I'm using LinFu's dynamic proxy to add some advice to some classes. The problem is that the proxied objects can only intercept virtual methods and will return the return type's default value for non-virtual methods. I can tell whether a class is proxied or not based whether the class or any of it's method has an interception attribute, e.g. [Transaction] Is it possible to write a ReSharper 5 structural search that would warn if any non-virtual public methods are defined on a class with an interception attribute. E.g. Ok public class InterceptedClass { [Transaction] public virtual void TransactionalMethod() { ... } public virtual void AnotherMethod() { ... } } Bad public class InterceptedClass { [Transaction] public virtual void TransactionalMethod() { ... } public void AnotherMethod() // non-virtual method will not be called by proxy { ... } } Many Thanks.

  • WPF application which calls an API, which needs a message pump

    - by Griffin
    I have a WPF application that calls an API to operate a device (a scanner). This API is COM based, and internally has a hidden window that the scanner sends messsages too. The intent of the API is to turn those windows messages into COM events. The problem is that the WPF application doesn't have a message pump, and therefore none of the messages are being delivered to the hidden window. Therefore none of the events are fired and it looks like the scanner is not responding. How should I create a message loop in the WPF application that will be able to dispatch messages to the invisible window?

  • VMWare Workstation Linux Host performance tuning

    - by Hoghweed
    I need to improve my linux hosted vmware workstation for using multiple virtual machines at the same time. I feel very stupid I lost a great blog post link which I found last month (and I'm not able to find it again..) so I try to ask here if anyone can help me: This is my host (laptop): 16GB DDR3 Ram HDD Hybrid 750GB 7200 (8GB SSD Cache) Mint 15 x64 Kernel 3.9.7 swappiness set to 10 The above are the important things about the host. So, My need is the ability to run 2 or 3 VMs at the same time. The lack of performance is about the disk, The last time from that blog post I lost, I setup /tmp to be mounted ad a memory partition and in my previous installation that was good, now I'm not able to find a good solution to tweak the things. I think with 16GB o RAM there will be no problems to run multiple VMs, but whe they start to swap or use the /tmp things going bad (guest cursor going too fast after a freeze, guest freeze and so on) Anyone can help me to fit a good host tweak and configuration to get better performance? Thanks in advance

  • Media Foundation: another way to call IMFActivate::ShutdownObject?

    - by KenC
    Hi, Here is a question about IMFActivate::ActivateObject and IMFActivate::ShutdownObject in Media Foundation. According to MSDN, the component that calls ActivateObject is responsible for calling ShutdownObject. But there are two examples not following this rule: http://msdn.microsoft.com/en-us/library/dd388503%28VS.85%29.aspx and http://msdn.microsoft.com/en-us/library/dd317912%28VS.85%29.aspx In these two examples, they call ActivateObject and then release IMFActivate interface without calling ShutdownObject method. This is going to lead to memory leaking, right? Or there is another way to release the resource occupied by the object? (Can I use IMFMediaSource::Shutdown to release the object instead of using IMFActivate::ShutdownObject) Thanks in advance.

  • What is the best VM for developing WPF apps from within OS X?

    - by MarqueIV
    All of my machines are Macs (Mac Pro, MacBook Pro, MacBook Air and Mac Mini (and Apple TV 2.0 too! :) ) but for my day-job, I develop .NET/WPF applications. Normally I just boot into Boot Camp and develop that way, which of course works great, but there are times when I need to simultaneously get to things on my Mac-side of the equation, so I've bought both VMware 3.1 and Parallels 6. Both work, however, even on my Mac Pro where I paid to upgrade to the better video cards (the NVidia 8600s I think vs. the stock ATI cards) the WPF performance bites!! Now this confuses me since both boast that they support not only hardware-accelerated OpenGL 2.1, but also hardware-accelerated DirectX 9 (VMware even allegedly supports DirectX 10!) via their respective virtual drivers and both can run 3D games just fine, even in a window. But even the simple act of resizing a WPF window that has a tiled background results in some HIDEOUS repainting and resizing behaviors. It's damn near closer to what you'd expect over RDP let alone a software-only renderer (forget accelerated hardware completely!) So... can anyone please tell me WTF WPF is doing differently? More importantly, how can I speed up the WPF performance? Should I switch to VirtualBox that also has support for DirectX? Or am I just gonna have to 'byte' the bullet (sorry... had to. So I like puns! Thank Jon Stewart!) and continue using Boot Camp?

  • Can a CLSID be different for the same program installed on two different machines?

    - by uberjumper
    I am using comtypes to generate wrappers for a certain com library. I am having certain issues with a few things, that are not being generated properly. I can get around this by doing the missing work, manually. However can i depend on the fact that CLSID's will not change? Lets say: I install a program with the com library Foo 1.0, now i install the exact same version of that program on another PC, will the CLSID's of the interfaces change? This might be a terribly dumb question.

  • Ubuntu VM "read only file system" fix?

    - by David
    I was going to install VMWare tools on an Ubuntu server Virtual Machine, but I ran into the issue of not being able to create a cdrom directory in the /mnt directory. I then tested to see if it was just a permissions issue, but I couldn't even create a folder in the home directory. It continues to state that it is a read only file system. I know a little about Linux, and I'm not comfortable with it yet. Any advice would be much appreciated.

  • COMException Problem

    Wondering if anyone could help with my problem.

I am wondering if it's anything to do with the threads? But I wouldn't know how to solve it if it was. The complete exception thrown is: The object invoked has disconnected from its clients.

  • Windows and file system abstraction - how much does it matter where something comes from?

    - by deceze
    I have come across the following phenomenon and would like to know how leaky Windows' file system abstraction is or if there's something else involved. I partitioned the hard disk of my MacBook Pro and installed Windows 7 (64 bit). The Bootcamp driver package includes file system drivers (right term?) that enable Windows to access the Mac OS HFS+ partition. AFAIK it's a read-only access, but it works. Now, I have some disk images of stuff I usually install, so I grabbed a copy of Daemon Tools to mount them. When I mount an image saved on the HFS+ partition, about two out of three installers on these disks (usually InstallShield) crash with all sorts of weird errors. Most are just gibberish that lead to all sorts of non-solutions on Google, one was "This application is not the right type for your computer, check if you need 32 or 64 bit versions." When moving the image files to another Windows 7 computer on the network and mounting them from the network share, they work fine. My question now is, why do applications behave differently depending on whether the read-only image file, which should be abstracted away through the read-only virtual Daemon Tools drive, is located on a read-only HFS+ partition or on a Windows network share? And I'll just roll this into the question as well since I was wondering: Does the file system of a network share matter? Does the client system need to understand the file system of the share host or is that abstracted away in SMB?

  • How to Use .NET Assembly from Legacy SQL Server 2000 DTS

    - by shyneman
    Hi All, I have a .NET assembly that needs to be called from a DTS package. There are two options I am considering to get this to work: 1) write a COM-callable wrapper for the .NET assembly and have the VBScript create the COM object to use 2) write a .NET command-line exe that uses that .NET assembly and have the VBScript execute that exe Can anybody comment on the pros/cons of either approach and which is the better way of doing this? If there are other solutions, I'd love to hear them too. Thanks a lot for any input.

  • How to clone a HDD and then use the clone with VMware (so that Windows works!)?

    - by Ahmad
    I have a system on which Windows 7 is installed, and I am trying to make a clone of its HDD image, which I then want to use in my main PC with VMware, so that I can boot Windows 7 off the cloned HDD. I used Ultimate Boot CD v5.1.1 with the system whose HDD I wanted to clone, and I cloned it using EaseUs Disk Copy, which comes with Ultimate Boot CD. The source HDD was 250 GB in size which had 3 partitions, while the USB HDD I attached to the system, which was supposed to be the destination/clone HDD, was 320 GB in size. I chose to create an exact replica, and so 250 GB worth of data (partitions, etc.) was copied exactly, and the rest of the space was un-allocated. I now connected this USB HDD to my main PC, fired up VMware Workstation 8 and defined a new Virtual Machine, and chose to boot off the USB HDD. Result is that when Windows is booting (from the cloned HDD inside VMware), I get the blue screen error before I reach the login screen. How can I change my methodology so that Windows even boots from the clone? I can change any tools I use, etc.

  • Tools required for a Web Development Project..

    - by RBA
    Hi, I wanted to design a project in linux which could contain programming languages(C, perl, PHP, HTML, XML etc) basically a web based project. Why i have chosen to build on Linux is because it is Open Source, and lot many things can be automated through scripting languages, which in windows i don't know. So, i have installed linux on a virtual machine(Host-Windows 2007 & Guest Linux CentOS), CentOS(command line interface). Since i am a beginner, so I want to know what all tools can be used to facilitate and ease my development process. Some which i know are listed below, and request you to please share your experience on this. 1) Using Putty so that can access the Linux machine from anywhere within the network. 2) Since i want to develop on Linux, but want to use windows as developing platform. So have downloaded Eclipse Editor (C/PHP) on windows. But want to know how can i access linux files from here?? 3) Installed Samba, and still trying to figure out how can i access linux files remotely on Windows. 4) Please share your experience, as how can i ease my development process. and what all tools i can use..?? Please let me know if you need any other clarification..

  • Windows VirtualBox failed to attach USB device to Linux Guest

    - by joltmode
    I have Windows 7 64bit Host system, and I am using VirtualBox 4.1.18 (r78361). I have an Arch Linux Guest OS. I have installed VirtualBox Extension Pack (to enable USB2 support) and added my USB device filter to VM. I have also installed the Guest Additions provided by Arch: virtualbox-archlinux-additions (but I have no idea whether it's actually needed for my environment). I can see my USB device from VirtualBox Devices menu. Whenever I am trying to access it, I end up with: Failed to attach the USB device Kingston DT 100 G2 [0100] to the virtual machine Archlinux.

  • Is Hyper-V server suitable as a desktop testbench?

    - by Thomas.Winsnes
    At the moment we are running a test bench with several desktop computers, that are reimaged every time we need to test on a different operation system. Also because different versions of our software is tested on each image, we have to install our software every time we want to test it. The problem we have had with going with a virtualization technology is that our software is depending on directx/opengl and 3D acceleration, and this has not been something that virtual machines have excelled at. With the release of SP1 for Windows 7 and Server 2008 R2 Hyper-V has gotten better 3D acceleration support, so we are looking into virtualizing our testbench using this. Our test scenario would most likely be something close to this: 1. Remote into the hyper-V server and load the test VM needed for the current tests 2. Remote into the VM and install the new version of the software 3. Run the tests It would be nice, but not essential, if our support team could remote into the VMs to match the users OS+software combination when doing support. Does anyone have any experience with this kind of settup with hyper-v?

For a start, we plan to build and start the following VMs - all with Windows Server 2008 R2 x64: Active Directory server MS SQL Server 2008 R2 Automated Build Server SharePoint 2010 Server for hosting our public Web site and our internal Intranet for a few people. The load on this server is going to be quite insignificant. 2xSharePoint 2007 development server 2xSharePoint 2010 development server Beyond that we will need to build several SharePoint farms for testing purposes. These VMs will only be started when needed. The specs of the new rig is: Dell R610 rack server 2xIntel XEON E5620 48GB RAM 6x146GB SAS drives Dell H700 RAID controller We believe the new server is going to make our VMs perform a lot better than our existing setup (2xIntel XEON, 16GB RAM, 2x500 GB SATA in RAID 1). But we are not sure about the RAID level for the new rig. Should we go for having the the 6x146GB SAS drives in a RAID 10 configuration or a RAID 5 configuration? RAID 10 seems to offer better write performance and lower risk of a RAID failure. But it comes at a cost of less drive space. Do we need RAID 10 or would RAID 5 also be a good choice for us?
