• Software Development for Windows Vista Using LUA/UAP in custom applicatons

    Hi, The December CTP of Vista has a modified version of UAP/LUA. There's a shield icon (windows colors) next to any setting that requires aleveated status (brings up the verification dialog instead of an earlier dialog that asked for admin password). Also, for other tasks such as opening a file, modifying registry, modifying the drive, etc the dialog pops up asking the user to verify the action. The question being, if I have several settings in my application that I'd like to be either Admin specfic or just out of concern I don't want the user to click on that unknowingly (i.e. might pose a danger to the system/security, etc). What should I be doing are there APIs in the platform SDK/Windows SDK for Vista that allow me to b ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How can I eliminate the automatic generation of the arm subfolders and arm entries

  The editor generates automatically two subfolders ../data/missions/arm and .../data tgl/arm and fills those folders with entries. Those entries are not helpful after finished game development. How can the automatic generation of these folders and entries be eliminated There's no single line that you can really remove to do this as it's engineered into the ARM stuff. If you didn't want to remove any of the code you could always add an action to the build script (Like an Exec task) that went in and deleted those directories. It might be simpiler to do. I think it leads to a good suggestions of having a way to turn that off. Are they being generated even though there are no files ...Show All

• Visual Basic Send text to an application's console screen?

  cmd.exe provides a very useful feature; if I have a program I want to run, and I know that I will want to type in 1, then 2, then 3 to answer the application's prompts, I can simply copy-and paste the following into a cmd window: application.exe 1 2 3 My GUI has to invoke a certain command-line application, and the command-line application needs to get certain input typed in...(but I don't want the user to type in the input, I want to somehow send this from VB, or really C# or C++ or anything else anyone can come up with). Any suggestions I would check out pipes. Maybe you can pipe the input to the command-line in from VB or from a pre-saved text file. http://www.microsoft.com/resources/documentatio ...Show All

• Microsoft ISV Community Center Forums Summing up hours on form based on parameter query

  Hi there - im finalising my new activity system but i have one issue. on an activity form i have certain fields for information purposes that are non editable - they are 'hours worked with client' , 'hours worked this month' and 'hours worked for the day'. The first 2 fields are populated automatically by opening recordsets on form load or companyname exit and summing up the hours based on the relevant query where the criteria ensures that the query is already populated. However for the 'hours worked for the day' field the query is a parameter query (qrytodayhours) where activitydate = Forms![frmactivity]![activitydate] and i was then hoping to enter the following code to sum up the hours using a recordset on the on exit of the acti ...Show All

• Smart Device Development Resize length of label (to fit text in it)

  Is there a way to resize the length of a label so that all text within it will fit I'd like to resize the label on the fly to match the text within it. Thanks again! try adding an event handler for textchanged either 1. In your form. 2. extend the label control and handle textchanged then add this private void label_TextChanged(object sender, EventArgs e) { Graphics g = CreateGraphics(); label1.Width = (int)g.MeasureString(label1.Text, label1.Font).Width + 3; // Use this.Width, this.Font and this.Text if you are extending the Label control to make your own user control } I add 3 to the width as just an extra buffer space so the last char doesn't get cut off.. You can play with it and make it ...Show All

• .NET Development AppDomain.Unload doesn't unload all assemblies

  Hi! I'm creating a small service app that on a timed interval checks a database for program updates. I would, of course, like this app to take as little memory as possible. Since a loaded assembly can't be unloaded until the AppDomain is unloaded, I decided to create a second AppDomain and load a service-class, that exists in a separate assembly, in it, that checks the database. However, AppDomain.Unload doesn't free the memory/assemblies that the service class/assmebly required. When the service app is loaded, it requires about 9Mb of memory, which is good. When the service class is executing it peaks at 29Mb. But when I call AppDomain.Unload, it only goes down to 21Mb. I would expect it to go down to something near 9Mb, wouldn' ...Show All

• Visual Studio 2008 (Pre-release) Message Security with X509 certificate - Unexpected Locating of certificate

  I have implemented an example with message security and certificate authentication. For this reason I created certificates testsvc.crt and testclient.crt , which should identify the service and the client respectively. In my test example the client and service should run on one machine. To make this example working I imported certificates in the store as shown bellow: CurrentUser Personal Store: testclient.crt CurrentUser Trusted People Store: testsvc.crt LocalMachine PersonalStore: testsvc.crt LocalMachine Trusted People Store: testclient.crt Unfortunately with this configuration the service is not able to authenticate client, although the client’s certificate is in the LocalMachine Truste ...Show All

• Visual Studio 2008 (Pre-release) How do I go about adding this kind behavior?

  I need to provide some custom context around method calls on my service. By "custom context" I mean that I need to set something up before a method executes and destroy it when the method is done. This context is purely for the server has no ties to the message data at all. What type of WCF extensibility approach should I use for this I'm aware of behavior extensions, IExtensibleObject, IServiceBehavior, etc., but I'm having a problem figuring out exactly which approach to use to achieve these exact "before method/after method" notifications that I need. Thanks, Drew In case anyone's interested, I've also documented a way to add context beyond the lifetime of operation call and i ...Show All
