Add reference DLL issue in Visual Studio - visual-studio

I am using VSTS 2008. I have two projects (both are written in C#) in one solution file. Project 1 depends on the output (DLL2) of project 2. So, in project 1, I am using "References --> Add Reference --> Browse", then find and select the DLL2 generated by project 2.
My question is, I am not sure whether using such method to add reference will result in some my local computer specific file path dependencies? In more details, suppose both of projects are located in folder d:\testprojectsolution (d:\testprojectsolution\project1 and d:\testprojectsolution\project2), I want to make sure that if I copy the whole solution folder d:\testprojectsolution (with the same structures of project1/project2) to other people under different location (e.g. c:\my documents\sampleprpjects\projects), they could build successfully (not dependent on any specific file path on my local machine, for example, no need to find files under d:\testprojectsolution\project2 or something).
If my approach to add reference dependencies could result in some specific file path dependencies, please let me know how to solve this issue. :-)
thanks in advance,
George

Instead of adding the reference using Browse, add it using Projects tab. It'll automatically consider the project dependency (and thus build order) and other stuff.

Where to put content, in Installer project (WiX) or in code project

So I see two solutions to my current problem, but I was wondering what the pros and cons are, or if there is a defacto best practices approach.
So my current project has a number of configuration files, help files, and other external content. I need this content local to run and debug the application. Currently we duplicate this content in a standard windows installer project. This clearly is a bad idea. We are moving to a new setup that uses the WiX installer, and I'm currently setting the project up next to the code project and trying to figure the best way to share resources. I see two solutions.
One is that I can put all the resources in the WiX project and then add them as links in the code project. This way I know what I'm debugging is installer.
The other option would be to leave the content in the code project and path into it in the installer using the reference variables.
Right now it seems 6 one way, half dozen the other. Any persuasive arguments for either method?
Assuming that these configuration and help files are going to be installed in the same directory as the executables then definitely put them in the code project, mark them as Content, and add a reference to the code project to the installer project. If you're using WiX 3.5 the files will be automatically included in the installer along with the executables, which makes writing simple installers much easier.
For earlier versions of WiX or more complex deployment scenarios (where the content files could be going into different directories) you would still put them in the code project but then you'd use File elements with a relative path or reference variable in the Source attribute to include the the content files from the code project directory.
I don't believe that putting the content files in the WiX installer project directory instead of the code project directory will do anything to ensure that the version you use to debug will be the same as the version installed. That can only be ensured by thinking through the process of how your application finds these content files and making sure the right versions are found.
So going back to the simple case where the content is in the code project and marked as Content, and it will be installed and loaded from the same directory as the executables, then it is only a matter of setting "Copy to Output Directory" to "Copy always" or "Copy if newer" and then you can be sure the versions used in debugging and the version installed will match.

How manage references in SVN/Visual Studio?

For a long time looking for a way to manage references, I haven't found any ideal way.
The main problems are:
1-) Should I include all projects that I use in same Solution and reference the Project? Or reference just the dll file?
2-) If I should reference dll file, the best way is to create a ReferencedAssemblies inside each project or a main folder at svn root?
3-) Its ok paste and reference dll´s inside bin folder of my project?
4-) Its ok add and commit dll´s inside bin folder of my project? This way when a new devoloper checkout the project, it will compile perfect, but isn´t default behavior of visual studio, all source controls ignore bin and obj by default, just adding .refresh files(for web-site project)
Someone can help me?
1) If you include projects in your solution that are already checked in somewhere else, you can change the SVN binding for that project at the solution level in Visual Studio. (File > Source Control > Change Source Control). You would change it to point to wherever it's located in your SVN repo.
2) If you have a lot of developers on different machines all wanting to use the same libraries, it's probably easier to have a common place for all your third-party libraries/assemblies. There's no point in having them copied all over the place in your SVN repository.
3) No, it's not usually ok to do this. I would avoid it (unless somebody has a valid reason for it).
4) Never commit your bin folders. The default behavior is such for a reason. The .refresh files are byproducts of the old Web Site projects and they are fine.
1) In the typical scenario yes, you should reference all projects that you own. But you should make a decision according to frequency of changes made to referenced projects. For example if you have an open source library it is better to include it as an assembly, cos you probably will not change this code frequently.
2) Typical approach is to create separate single directory at SVN root and place assemblies there in different sub-folders according to assemblies type. Here is how my current folder looks like:
3) No, it is better to reference assemblies from some other from bin folder. All referenced assemblies will be copied to the bin while building process. Also note that the purpose of *.refresh files in the bin folder is to prevent you from having to copy new versions yourself.
4) No, you should never commit your bin folder cos you can rely on *.refresh files for WebSites and just forget about this problem for other project types.
1) I'd argue it depends upon your particular situation, especially since Visual Studio is pretty flexible on what projects are included in solutions. (It's not tied to a directory structure.)
We have a couple applications that have one solution with a number of projects contained within (for each 'piece').
2, 3, 4) For referencing and including files within a project, why not just use the functionality built into Visual Studio? Adding references in this way adds the items to your csproj (vbproj) files.
(Based on my research, if you're not referencing a project that's part of the solution, put the DLLs in a directory everyone on the team can access and use that when adding the reference. In the project file it ends up looking like this:
<Reference Include="Elmah">
<HintPath>\\pathInformation\shared assemblies\ELMAH 1.1 32-bit\Elmah.dll</HintPath>
</Reference>
)
This also means that you don't have to commit DLLs; if anything changes the project file will be updated accordingly.
(I'll admit, I'm unsure about that last point. I've seen a lot of people check in external libraries, like ELMAH. I generally follow those who tell you to ignore the bin directory entirely.)

Visual Studio 2008: How do I include project output as an embedded resource in another project?

I have two projects in one Visual Studio 2008 solution. I'd like to use the primary output from one of the projects as an embedded resource in the other, but for the life of me I can't find any way to accomplish this.
If I simply add the output file as a resource, then it doesn't seem to change when its source project is rebuilt. I even have the project dependencies/build order set up properly and this does not seem to help.
Anyone have any hints for me?
Thanks!
the best option is to "reference" the other project as if it were a class library.
that way you make sure the whole references tree is copied to your output dir.
When you add an existing file to a project, Visual Studio copies the file into the project's directory.
Any subsequent changes to the original file are ignored.
There are two workarounds:
Add a post-build action to the first project that copies its output file to the second project, and edit the dependencies so that the first project is always built first.
Add the output file to the second project as a link (Click the down arrow next to the Add button in the open dialog).
This will reference the file from its original location without making any copies.
Set the output directory of the project that generates the resource to point to the resource directory in the project that uses it.
If that's not possible for some reason, use a post-build command (also available in the project settings) to copy the file there.

Place all output dlls in common directory from Visual Studio

I have a couple of different solutions, in which some projects may depend on output from projects in other solutions. To manage this, I've been copying dll files from the /bin/ folder in each project to a shared library location after build, and then copy/reference them from there to the dependent project.
However, as the library solution gets larger, this tends to become unmaintainable. Too much of my time is being spent traversing solution directories in Windows Explorer looking for /bin/ folders, and trying to figure out which one, or which ones, of the dll files from each one I need.
Is there any way to give Visual Studio a hint that I want all projects in a solution to have the same output directory? For example, a /bin/ folder directly under the solution folder, where all projects put their output.
If possible, I'd like to achieve this without hard-coded post-build events that copy the files, since that will fail if a project output changes file name, or adds another file. I'd rather like to change the location of the actual output directory - the location of $(OutDir), if you will.
I know you said you don't want to use post build events, but your reason as to why not intrigued me. It sounds like you might be hard coding the name of the .dll in your post build event. That can easily be avoided.
xcopy "$(TargetDir)*" "c:\common\" /Y
The * would just cause everything in your bin/Debug/ folder to get copied to your common folder. You could also just copy dlls if you want. Or, if you use $(TargetPath), you'll copy just the 1 dll that is the result of the project, and not any other related dependencies.
UPDATE
The way we do it is each projects entire bin folder is copied to a subfolder. Suppose you have 2 projects, WebUtil and HtmlParser, where WebUtil depends on HtmlParser. For both projects, use xcopy "$(TargetDir)*" "c:\common\$(ProjectName)" /Y. This will create c:\common\WebUtil\ and c:\common\HtmlParser. In WebUtil, add a reference to c:\common\HtmlParser\HtmlParser.dll. There will now be 2 copies of HtmlParser.dll in c:\common.
c:\common\HtmlParser\HtmlParser.dll // the most recent build.
c:\common\WebUtil\HtmlParser // what was the most recent build when WebUtil was built
This has all kinds of advantages. If you change the API of HtmlParser, WebUtil will continue to work, since it will have the older HtmlParser.dll until you try to rebuild WebUtil (at which point you'll get build errors because of the changed API).
Now, if a 3rd project got in the mix that depended on WebUtil, and you're using some part of WebUtil that exposes classes in HtmlParser, then you'll need to add a reference to both projects from your new project. When you add a reference to HtmlParser.dll, use the one in c:\common\WebUtil. You do this because you're only including it as a necessary requirement of WebUtil. Now you'll always have the version of HtmlParser.dll that matches your current version of WebUtil.dll.
I hope that makes sense. It can definitely be a tricky thing to manage. Just wait till you have to start pulling down all your dependencies using svn:externals =P
You can set the output directory in each project properties.
Right click on the project, select Properties
For C#, it is one of the Build property page, under Output, Output directory.
In VB.Net projects, it is on the Compile tab, in the textbox at the top.

In Visual Studio how to give relative path of a .lib file in project properties

I am building a project using Visual Studio. The project has a dependency on a lib file generated by another project. This project is there is the parent directory of the actual project I am building.
To be more clear,
I have a "ParentDir" which has two subDirectories Project1 and Project2 under it.
Now Project1 depends on lib generated by Project2.
In the properties of Project1, I am trying to give a relative path using
$(SolutionDir)/../ParentDir/Project2/Debug
But this does not seem to work.
Can you tell me where i am going wrong, or suggest the correct way of achieving this.
Add the dependant project to your solution and set it as a dependency of the other project using project properties. Then it just magically works ;).
A solution is just a file that describes a set of related (interconnected) projects and the relation between them, so this is the correct way of doing it.
Your current dir is your $(ProjectDir), that is where .vcproj file is.
So, just write ../Project2/Debug, that will do.
Even better, write ../Project2/$(ConfigurationName) for all configurations
thus you will be always linking to the correct version of that lib.
I think Visual Studio does not expand the relative path properly when the ".." is placed somewhere in the middle of the path string. It only knows how to expand ..{sub-path}.
