• Windows Forms Client changes to app.config after click-once publish and delivery.

  I have a VS 2005 Win Forms Application that is being developed for a client. Once system tested, I want to hand over the application to the client with some instructions for installation and setup in their environment, i.e. they need to specify connection strings, web service url's, timeout periods, etc in the app.config. There are many settings here that they could potentially change (10-15). However, when I use click-once to publish the application, how does my client change the settings within the app.config It seems to me that once published, these values are locked.. even if I change them in the app.config before installation ...Show All

• Visual Basic Real Time Data Monitoring

  Hi All: I am writing a project to analyze data from a device in real time. The idea is to pick up the signal from a sensor through serial port in 20Hz and to do some calculation on the data received, and plot out the result on the form. I use a background worker to read data from the serial port and do the calculation within a Do Loop. There is no problem on this. My problem is that when I try to use GDI+ to plot the results on the form, data are not refreshed instantly on the form. I use a Collection of Single to store the data for plotting. Questions are: 1. Can Vb2005 do the job Or VC2005 is better 2. Is there a control ...Show All

• SQL Server I need a second opinion on SQL 2005 syntax

  I am not that experienced in SQL 2005 and I'm trying to debug a stored proc (written by a far more experienced programmer which is why I'm appending here.) At the top of the proc is the statement ' DECLARE @BillActualRoom bit'. If I understand correctly this is a local variable. Later in the code we have the statement 'SELECT @BillActualRoom = 0 FROM BillingOptions WHERE CenterID = @CenterID' where @CenterID is an input parameter. The table BillingOptions does have a field called 'BillActualRoom' and it is a bit. My question is this: Does this SQL statement make any sense at all (My gut reaction is no but I ...Show All

  Hi everyone, Anybody knows if Microsoft sells directly the graphical User Interface (3D colorful buttons, frams, etc) as activex or dll I searched on Microsoft website, but rendered a result that many 3rd parties have this as products.

• Windows Forms ClickOnce On-Line Appliation not Getting Latest Fixes When Publishing

  I have a ClickOnce application that I have successfully deployed. Now I have made some bug fixes to that original application and have published to the same directory as previously. But when someone accesses the application through the "Run" button they are running a version without the bug fixes. When I debug the application locally the fixes are present and working. Why wouldn't publishing the application get the latest fixes to the clients I have fixed the above issue by making sure that checkbox is checked. I am now able to successfully publish but now I am getting an error when the application is starti ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. rendering to texture is clipped to clientsize inwindowed mode?

  I posted this already in the W32 Graphics discussion section, but since I am pretty hard pressed with the problem I am also posting it here: I wrote a small application using managed DX9 in an application running in windowed mode. The clientsize of the window is 800x600. In this application text (and sprites) are rendered to a 1024x512 pixel texture. The viewport settings seem to be correct after the SetRenderTarget call (1024x512), and I activated no clipping whatsoever, but the text and sprites drawn to the texture still are clipped to the size of the client area of the windows form and I cannot find any refer ...Show All

• Visual Studio Cross Project builds

  We have a solution that contains both c# and c++/cli projects.  When building using msbuild, we are directed to use devenv /build to execute a build from command line.  In the Feb CTP Professional version, I got this to work fine.  I just updated to the latest Visual Studio 2005 Standard Beta 2 (April) and with the same commands I get errors like: "The application for project 'c:\...\code\Parser.csproj' is not installed.

  I have a class called Playlist . Playlist exposes an ObservableCollection called Entries and also exposes a DependencyProperty called CurrentEntry . Now I would like to build a control called PlaylistView that will display the entries in the Playlist and highlight the CurrentEntry . My idea was to build a control based on ItemsControl and have a public property of type Playlist . When the Playlist property is set, the ItemsControl s' ItemsSource would be bound to the Playlist . Entries collection. But whenever the value of Playlist . CurrentEntry changes I need to update update the items styles accordingly. What's the best way to do t ...Show All

• Visual Basic Displaying at Pixel Level in VB 2005

  I want to generate a graphic in a picture box control where the color of each pixel is determined by particular values calculated for each pixel. These values are manipulated in such a way that I come up with three values (each in the range 0-155) and I want to use these for the RGB values of the color of the associated pixel. My question is: In VB 2005 how do I set a particular pixel to a color with a given set of RGB values In VB 6 I used to use the PSET function but it is not available in VB 2005. Thanks. ...Show All
