• Visual C++ Finding currently visible desktop

  Hi there, how can I find the currently visible desktop By calling EnumWindowStations and EnumDesktops I get a list of all available desktops. But is there a way to figure out which one of them is currently visible I've tried to find the visible desktop by comparing the desktop handle, returned by the OpenDesktop function, to the desktop handle received by calling OpenInputDesktop. The result is that the default desktop is always the one currently receiving user input. But by using the default desktop my window always shows up at the desktop of the first user logged on to the system after reboot. No matter if this desktop is currently visible or not! What am I doing wrong Or what is the right way to search for the currently vi ...Show All

• Visual Basic Generating a Unique String

• .NET Development Registy entries

  I have a VB.Net application ('05) that is useful on the OpenWith list. While I know it's possible to write code that will 'officially' associate my application with particular extensions, I have avoided that because I always found it annoying to have a new application presume to take over my file associations. All I really want to do is have my application show up on the list, so the user can select it as desired. The problem I am having currently is that my application shows up on the list and correctly opens the file when selected; however, the OpenWith list does not display either my icon, or, more importantly, the name of my program. I can manually correct the latter by going into the Registry and adding Data to the appropriate prog ...Show All

• Internet Explorer Development Native XMLHttpRequest permission problem accessing local files

  There's a permission problem when access local files by the native XMLHttpRequest introduced in IE7. Here's a testcase. Just set up a 1.html with whatever in it, then run it. It fails on IE7 but works fine on other browsers such as Gecko-based Firefox, WebKit-based Safari. Anyway, this works fine too by using the ActiveX XMLHttpRequest. <script> var url = "1.html"; // local file http = new XMLHttpRequest(); http.open("GET", url, false); alert((http.status==200 || http.status==0) http.responseText : "HttpGet Error Status: " + http.status); </script> ...Show All

• Visual Studio Express Editions reflection - createInstance on an object which doesn't have parameterless constructor.

  Hi, I am using reflection to all the class in a dll and their methods. While invoking some of the methods, my call to Activator.CreatorInstance fails since the class didn't have a parameterless constructor. Is it possible to find the constructors (with the parameters) and then create the object with those parameters Ignatius From the sounds of it you’ve already got an instance of the Type... if that is the case you can simply call GetConstructors() on that type to receive a list of the public constructors. After you’ve got that list you can then call GetParameters() on each one to get a list of their respective parameters so that you can more easily determine which one you want to ...Show All

• Visual Studio Team System Granular Security on Public WIQ

    Yet another security granularity post. It seems that via the project security options that if the privilege of "edit project information" is turned off that this prevents the members of that group from creating public WIQ. That seems to make sense. That is project level information. Is there any security mechanism to granularly turn the ability of a specific group with "edit project information" set to false to allow them to have privilege to provide public WIQ I can't imagine what the action id would be other than a generic_write but is there an object other than the PROJECT objectClass I have poked and can't seem to find what object I might could even register or is registered in the authentication repository for that f ...Show All

• Visual Studio Self-contained Embedding

  Is it possible to make a self-contained embedding as AClass->BClass->AClass At present there are quite severe restrictions on the domain models that we support.  Every class can only be embedded once; and every class that can have a shape on the toolbox must be embedded in the root class.  The consequence of this is that the shape you propose is not supported.  These restrictions will be relaxed in our V1 release.

• Visual Basic Checking MS-office service pack levels

  I have a vb.net app which does a number of checks on a user computer and reports these back to the help desk. I would like to determine the best way of finding the service pack level for the installed version of Microsoft Office. Using vb.net. Any pointers would be most appreciated. Each Office application also has a COM/Interop library that comes with the application(ie you must have the office app installed for your application to work on the clients machine). You must first reference this library at the project level(Project - Add Reference - COM - Microsoft Excel 11.0....) and then inside your class use an imports statement like: Imports Excel = Microsoft.Office.Interop.Excel ...Show All

• Smart Device Development Question on COM

  Hi All, I am trying to write a COM component that inherits from another class. Essentially, my COM component is a plug-in that enables another application to control a device. I am in a bit of a dilemma now. My component will expose a particular interface to all other applications including the main device-controller application. I would like CoCreateInstance(...) to create an instance of the device when it is called. However, this instance should also inherit the functionality of a GenericDevice object. The implementation of some of the Generic Device functions is in the main controlling application. Hence, when I am writing my component I am also making a link to the lib file of the controlling application. My problem i ...Show All

• Visual Studio Team System Add reference to a separate team project

  We're building several libraries that we're going to use in many of our upcoming projects. One of them needs to use a library that is in a separate team project. What's the best way of doing this What I'd like is to be able to add a reference from the team foundation server's copy (because that'll be the checked-in release copy), and any time someone checks in a new version and builds a release DLL, it'll update that project. Is that possible Any other ideas Thanks, Johann MacDonagh We ended up solving this by standardizing the location of our local copies of team projects and adding references to DLLs built in the Release folder of projects. So although the "Path" to external reference DLLs i ...Show All
