• Visual C++ Impersonate user (seteuid/setegid for Windows)

  Basically, I'm new to these forums, so I apologize if I am posting this to the wrong place. I am currently porting over code that was written for Linux that utilized the seteuid and setegid functions.  These functions allow a high privileged user (root) to impersonate a user/group when trying to run certain system-level functions. Basically is there something like these functions that exist in Visual C++    I'd like to be able to call functions, like requesting to delete a file, while impersonating a user.  I'd like to do this without having to run the process as that user.  This way, I could perform the same function over and over using different user profiles, if needed. Please let me know if this makes sense ...Show All

• Software Development for Windows Vista Per Pixel Alpha subthemed controls

  New to Vista themes is visual styles that have perpixel alpha values. In my various incarnations of apps testing theming in Vista, I've started with a button on a Windows Form, subtheming it to a StartMiddle button, which works as expeted (the start menu image appears in the middle of the button area, the edges of the button image fade with the background, and the rest of the button area is invisible). I then created a glass pane (no frame, useing DwmBlurBehind), and then drew the TaskbarComposited::Taskbar background on top of the window, which then emulates exactly the feel of the taskbar itself, with it's blurry glass effect, with the taskbar image partially transparent. I also had a button subthemed to StartMiddle, and it appeared exac ...Show All

• Software Development for Windows Vista Xaml only UIElement and the Ruleset Editor

  Hi, Does anyone know if it is possible to create a ruleset for a xaml only ui element (i.e. it has no code behind) I can serialize and render the xaml but would like to apply some simple rules to the element content (e.g. a value in a field has been supplied) If anyone knows the answer or can point me in the right direction I'd be grateful. Trev Trev, This appears to be a WPF question, since you're talking about UI, and fields being completed on the UI. Although WF and WPF both use XAML serialization, they interpret the XAML differently. I suggest that you ask your question on a WPF forum. Dave ...Show All

  Hello.  I have a dataset that I filled with data and I want to write it to an xml file.  I know how to use the dataset.writexml() command and it does not output the data exactly like I need.  The xml output contains the xml declaration information and the dataset name as the root node.  I do not need these.  I found out how to remove the xml declaration with the following code: Dim xws As Xml.XmlWriterSettings = New Xml.XmlWriterSettings() xws.ConformanceLevel = Xml.ConformanceLevel.Fragment xws.Encoding = System.Text.Encoding.Default xws.Indent = True xws.IndentChars = " " xws.OmitXmlDeclaration = True Dim xw As Xml.XmlWriter = Xml.XmlWriter.Create( "c:\aa.xml" , xws) ds.WriteXml(xw) ...Show All

• SQL Server Updating Database User SID in SQL 2005

  Hi all We're currently undertaking the development of our first SQL Server 2005 database and we've stumbled across a problem with our method of deployment from Development through System Test, UAT and, finally, to Production. Under SQL Server 2000 we would build a new database in Development and assign permissions to a specific database user which was linked to an appropriate Windows Login - the whole build process was scripted. We would then hand the mdf and ldf files over to the Operations team who would attach the database to the System Test server, create a new Windows Login (appropriate for the environment), then run a script which would update the SID stored against the database user to the SID of the appropriate login. e.g ...Show All

• Visual Studio Express Editions Form Selection

  I have a small project that I am working on, On do a SQL search for phone numbers. My actuall question is: When I get my result from the search I want to have a form window popup or popup tab(prefered) depending if the result is either a CELL, Cell Modem, Deskphone, Office phone etc. If this is possible(which I beleave that it is) how would I accomplish such an easy task Simply look at the data being returned and based upon the value of this, determine which form/tab to display. This example takes the initial value from a textbox content instead of a SQL search but ultimately depending upon the content loads and form and selects a tab You should get the general idea and simply bolt you sql search result at the top.
