• Platform configuration for projects in VS 2010

  - by Thomas Wanner

  I have a third-party project type in Visual Studio which for some reason only supports the .NET Platform configuration for the build, for all other (standard C#) projects in the solution I only have AnyCPU. Unfortunately, ever since upgrading to VS 2010 it produces following error when built : Error 39 The OutputPath property is not set for project 'ReferencedBusinessProject.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='.NET'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets 483 10 CustomTypeProject It's pretty much descriptive in what is missing but I haven't found any way to fix it so far. Do you have any idea how this can be resolved or what can be the problem ?

• What VS Projecttype for Model and Database?

  - by Tim

  Hello folks, i've just started a new asp.net project which could increase fastly(a small erp-system for our company). So i thought it would be a good idea to split at least the model from the view/controller(the asp.net project). Because it could be that i need to access some classes and the database from a windows app in future, i dicided to put the Model into its own Project. What Visual Studio 2005 Professional Projecttype is most suitable for this requirement and why? SqlServerProject (DB is MS Sql Server 2005 EP) Class Library Web Service Application Database project no separate Project/other(keep in mind VS 2005 has no ASP.NET MVC-Project) Thanks

• VB.Net 2008 Chrome or Firefox control

  - by AndyD273

  I'm trying to figure out a way to have multiple sessions at the same website at the same time. I've been using the SHDocVw.InternetExplorer control in Visual Studio 2008 to open a web browser and log in, but at times we need to use a separate login. I haven't found a way to do this using just internet explorer (it just uses the credentials of the first login), so I figure if I can find a similar control for another brower that allows DOM level access then I can just use that. If anyone knows of anything I can try that would be very helpful.

• How do I fix "error 1004, 0, Unable to find property" in an Entity Framework 4 WinForms application?

  - by Ivan

  I've designed an EF4 model (quite complex inheritance, lots of small tables incl. multiple self-referencing), generated (table-per-type) a database and inserted some basic data manually. It works fine in an ASP.Net Dynamic Data Entities web application with full automatic scaffolding. But when in a WinForms application using the same model (I share it as a part of a class library) I construct a query and bind a combo box to it (the way it's shown here), I get an InnerException {"Internal .NET Framework Data Provider error 1004, 0, Unable to find property... I've found a question about the same problem here (incl. a sample to reproduce the error) but no answer. I use final Visual Studio 2010, no beta.

• ASP.NET 4 UpdatePanel and IIS7 Problem

  - by rwponu

  I have an ASP.NET 4 webpage that contains an update panel which just allows me to add a few items to a drop down list without reloading the entire page. The page works fine on the Visual Studio 2010 ASP.NET Development Server, performs the Async call and the page is properly laid out. However, when I deploy the page to IIS7, the Async call no longer works (the page is completely reloaded) and the layout of some items on the page is incorrect. I used Fiddler to look at what's happening and it looks like there are 404's when the page tries to access ScriptResource.axd, with everything else working correctly. I think that has to do with the Javascript required for the call but I'm not sure how to fix it. Any suggestions?

• .Net Designer assemblies, C++\C# error

  - by greggorob64

  I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

• How to use a different assembly name for different configurations?

  - by Mark Ingram

  In Visual Studio 2008 (and others) when creating a .NET or silverlight application if you look at your project properties, it seems like you can only have one assembly name - across all configurations. I would like to compile my application as: MyAppDebug - in debug mode and just MyApp - in release mode Does anyone know if this is possible? Edit: It seems some people are questioning the reasoning behind the question, so I'll explain a little further: I'm working on a Silverlight application which gets automatically uploaded to our test site when I to a "build solution". The trouble is, the test team are now testing the online version, whilst I work on a new one. So, I want to have a url like .\MyApp.html for the regular version that the QA team will test and then .\MyApp.html?version=debug for the current version that I'm working on.

• ClickOnce disallow publishing of Debug builds

  - by LnDCobra

  Is there anyway to disallow publishing Debug builds when publishing ClickOnce aplications using Visual Studio 2008? I know this was asked before, but i can't figure out how from the answer. THe Accepted answer for previous question was: One thing you can do is add a condition to the .csproj or .vbproj file that MSBuild will check when doing a build. The condition would check if a publish is occurring and check if the build is a debug build, then do something like run an external tool or otherwise interrupt the build process or cause it to fail. Could anyone elaborate on that answer or tell me where/or how I can add this condition. [Original Question][1] [1]: http://One thing you can do is add a condition to the .csproj or .vbproj file that MSBuild will check when doing a build.

• Symbols taking very, very long time to load when hosting ASP.NET app in IIS

  - by joshcomley

  Hi, I'm hosting my project using IIS, running from Visual Studio. Whenever I recompile, on the first run it takes several minutes (on a not awful machine) to load all the symbols. Please see http://joshz.com/so/symbols.html for a list of the symbols that are loaded. At the bottom there is a ThreadAbortException, I'm not sure if this is playing a role. Any advice would be greatly appreciated; it's slowing my day down enormously! As a note: the project has never run quickly since I joined the company and started working with it.

• Suggestions for VS+Resharper keyboard shortcuts on a Mac

  - by John Miller

  I just upgraded to a Macbook Pro as my development machine but still primarily develop .Net applications with Visual Studio and Resharper (via VMWare Fusion). By far, the biggest obstacle I'm running into is getting used to the keyboard layout change (ex. not being able to do ALT-Insert). Do any of you Windows-on-Mac veterans have any suggestions on how to ease the pain of transitioning (without moving to an external keyboard)? Are you changing mappings via VMWare's keyboard preferences? Or are you using something like AutoHotkey? Any other windows development tips for a Mac newb?

• I Clean Solution'd my Winform App and now it's broken...

  - by Refracted Paladin

  I have a Winform App that uses a 3rd Party Library of Controls, DevExpress. I also created a bunch of Controls myself, extending those controls. Everything has been working fine when all of a sudden I opened VS today and on the Design Page all my extended controls were missing. I then tried rebuilding to no avail. Then I tried Cleaning and Rebuilding and made it even worse. Now I have tons(520) of erros stating things like -- Error 179 The name 'datBirthDate' does not exist in the current context D:\Documents\Visual Studio 2008\Projects\MatrixReloaded\MatrixReloaded\Controls\Member\ucGeneral.cs 339 17 MatrixReloaded also if I try to open a form or user control in Design Mode I first get this -- could not find type, "MyType" please make sure that the assembly that contains this type is referenced and then, if I click Ignore and Continue I get this for all Forms and Contros when I try and look at them in Design Mode -- Exception of type System.OutOfMemoryException was thrown Help!?!? When I googled I came across mostly references to VS 2003...I am on 2008 sp1.

• How do you add folder level documentation to C# assemblies?

  - by Elijah

  Me: I'm a relative new-comer to the .NET platform. Problem In Java, you can add package level documentation to your project by creating a package-info.java or package.html file and storing in the package folder. How do I add equivalent documentation to my project in C# using Visual Studio 2010? Background I like to write documentation describing my motivations in the package/folder level context of the source code projects that I am working on. I have become very accustomed to this workflow in a variety of languages (specifically Java) and I believe that it is a good way to document my project.

• Create a ActiveX with a MFC existing application

  - by Jesús Galindo

  Hello! I'm trying to convert my MFC application, a simple "PaintBrush" app that draws lines and rectangles (it's only a little test from another bigger application), to a ActiveX Control that a could embed into a Windows Forms Application (with Visual C#). I didn't found any tutorial for do this, and now, I'm not sure that this it's possible. I know how create an ActiveX Control recently created but not how convert an existing application. Have anybody know how I can do this? Thanks!

• How to place text on top of image in ReportViewer

  - by Christoffer

  I feel very silly asking this, since it seems like it just should work, but I cannot make it work and cannot find anything in the documentation about this. The problem: I'm developing an application in Visual Studio 2010 that is utilizing ReportViewer, rendering the report locally. In the report designer, I place a textbox on top of an image. This looks fine in the designer, but when rendering the report, the textbox is rendered below the image. Now, before you suggest it, I have tried placing a textbox on top of a rectangle (or other control) with the BackgroundImage property set. This works. But: I cannot find a way to rescale the background image to fit the control. Setting a different dpi for the background image does nothing. Simply rescaling the image to a different resolution is not an option, since I eventually want to print the report. Does anybody have a solution to this?

• How do i render a web cam filter instead of video file in directshow?

  - by Mr Bell

  How do i render a web cam filter instead of video file? I am looking at the vmr9compositor example included in the directshow sdk. It renders a video file. I would like to stream in the feed from the webcam. It SEEMS like this should be possible, but I dont have much of a grasp on directshow. It uses this method call currently: hr = g_graph->RenderFile( pFileName, NULL ); Looking at the playcap example in the sdk which can display the web cam feed in a window, I see that it uses hr = g_pCapture->RenderStream (&PIN_CATEGORY_PREVIEW, &MEDIATYPE_Video, pSrcFilter, NULL, NULL)); to display the web cam stream. pSrcFilter is an IBaseFilter. How can I can swap the video file in the vmr app with the web cam feed? Windows XP, Visual Studio 2008 C++

• Clean way to display/hide a bunch of buttons based on a ComboBox selection

  - by John at CashCommons

  I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid. Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing. Is there a way to do this? Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons. Thanks in advance as always!

• What is a good method to use with multithreading to simulate this?

  - by user1504257

  I am writing a program in c++ in visual studio to be able to handle a line at a park. I have all of my customers in a line at the park and I want to be able to service them using multithreading with openmp. When I put the pragma and such in, I have multiple threads servicing the same customer at the same time for each and every customer I create, not what I want. I want for example, if I had two threads and four customers, that thread one to do customer one while thread 2 does customer 2. Then I would like thread 1 to do customer 3 and thread 2 customer 4 at the same time. I don't know if its possible or if there is a better way, but I need to use openmp. Thanks for your input.

• Is there a efficient way to do multiple test cases in c?

  - by Ahmed Abdelaal

  I use MS Visual Studio and I am new to C++, so I am just wondering if there is an faster more efficient way to do multiple test cases instead of keep clicking CTRL+F5 and re-opening the console many times. Like for example if I have this code #include <iostream> using namespace std; void main () { int x; cout<<"Enter a number"<<endl; cin>>x; cout<<x*2<<endl; } Is there a way I could try different values of x at once and getting the results together? Thanks

• Linking to a C library compiled as C++

  - by Jacob

  I'm in linker paradise now. I have a C library which only compiles in Visual C++ (it probably works in gcc) if: I compile it as C++ code Define __cplusplus which results in all the declarations being enclosed in extern "C" { } So, by doing this I have a static library called, say, bsbs.lib Now, I have a C++ project called Tester which would like to call function barbar in declared in bsbs.h. All goes fine, until I try to link to bsbs.lib where I get the all-too-familiar: Tester.obj : error LNK2001: unresolved external symbol _foofoo And it always seems to be foofoo which cannot be resolved regardless of which function I call in Tester (barbar or anything else).

• Can a single solution hold projects from multiple repositories?

  - by cyclotis04

  I've begun setting up SVN repositories to store my code, and am wondering if a single Visual Studio solution can have projects from multiple repositories. I have a shared library with different helper functions, generic custom controls, etc, that are used by multiple projects, and hosted in its own repository. Then I have my project repository, which contains all of the program-specific code such as forms, etc. I know I could copy the shared library into the program's repository, then copy them back when I make changes, but I'd much rather keep them in different repositories so I can hit "Commit" and the general library commits to it's repository, and the program code commits to it. I'm currently using AnkhSVN, but if it's possible with other tools, I'll look into it. Preemptive clarification for all the "just use one repository" answers: The shared library is hosted in an online repository, viewable by anyone, but the program code is proprietary and resides on our office servers, so they need different repositories.

• Styling Windows Phone Silverlight Applications

  - by Tim Murphy

  If you have not developed with styles in Silverlight/XAML then it can be challenging and resources can be sparse depending on how deep you get.  One thing that you need to understand is what level you can apply styles and how much they can cascade.  What I am finding is that this doesn’t go to the level that we are used to in HTML and CSS. While styles can be defined at a page level if you want to share styles throughout your application they should be defined in the App.xaml file.  This is of course analogous to placing a style in your HTML file versus an external CSS file.  This is the type of style I will concentrate on in this post. The first thing to look it how styles associate to elements.  TargetType defines the object type that your style will apply to.  In the example below the style is targeting the TextBlock object type. <Style x:Key="TextBlockSmallGray" TargetType="TextBlock"> Next we use a Setter which allows you to apply values for specific attributes of the target object type.  The setters can be a simple value or complex.  The first example here is simply applying a color to the background property of the target. <Setter Property="Background" Value="White"/> The second setter example here is for the same property, but we are applying a the definition of a LinearGradientBrush. <Setter Property="Background"> <Setter.Value> <LinearGradientBrush> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset="1" Color="White"/> </LinearGradientBrush> </Setter.Value> </Setter> The last thing I want to cover here is that you can leverage the system styles and then override or extend them.  The BasedOn attribute of the Style tag allows this sort of inheritance.  In the example below I am going to start with the PhoneTextTitleStyle and then override properties as needed. <Style x:Key="TextBlockTitle" BasedOn="{StaticResource PhoneTextTitle1Style}" TargetType="TextBlock"> So now that we have our styles defined applying it is fairly straight forward.  Add the style name as a static resource to the style property of the element in your page and off you go. <Grid x:Name="LayoutRoot" Style="{StaticResource PageGridStyle}"> So this is one step in creating consistency in your application’s look.  In future posts I will dig a little deeper. del.icio.us Tags: windows phone 7,mobile development,windows phone 7 development,.NET,software development,design,UX
