I'm working with a C# and Linq to SQL Winforms app and needed to integrate backup and restores through the program. I used SMO and got it working pretty smoothly. The issue, however, is that the app is deployed using ClickOnce, which I like very much - but since I had to include the dll's the download size jumped from 3mb => 15mb. I know they've only got to download it once, but it also sucks for me as Visual Studio 2010 seems to upload the dll's every time and that takes a while on AT&T broadband (eh).
So, anyone have any suggestion on how I can work out an effective backup/restore solution without using SMO objects?
You can just fire plain ol'sql at the box via ado commands
You can use stored procedures to do backup and restore in lieu of SMO. There are a number of samples available on the web, including this one.

Additional info: I thought it might be helpful to say that my forms and classes are in the same solution as the already updated forms.
In our company we have this project which 3 people are working on it. One works on the database part, me and another colleague of mine are working on making the UI ready and relating it to database which is MS SQL Server 2012 and we are programming in C# in VS 2012.
The problem is that I made this one form ready, but the server version is ahead of me. That is, if I check in the whole program, I will damage the project as some forms has changed and the version I have is older. I tried right clicking and checking in only the forms and classes which I, myself made and I have their latest version. They check in without any error or anything, but the problem is, when my colleagues or myself(after deleting my source project) try to get latest version, my forms or classes doesn't show up.
We also tried to check in the whole program but only accept those pending changes which are made by me, still no success.
The problem is, we are kinda afraid to play with the server version as a lot of effort has gone into it.
Any help will be really appreciated as I'm stuck with this problem and the manager won't give me more parts of the program to make until we can come up with some way to deal with this.
You haven't mentioned merging at all but I think this is the answer to your question.
When you work on an older version of the code (because your local code is older, or maybe the whole branch of the code is older), you need to merge the code into the newer version. When you merge, any potential conflicts are detected and you can resolve all of them manually. There's obviously tools to help you - one is built into Visual Studio but you can replace it with an external tool which may work better for you. Either way, you need to decide how to merge the code. You have a few options:
take the whole code from the source (old code in this case),
take the whole code from the target (new code in this case),
merge the changes and take bits from each version based on your knowledge of the changes and how the code should look like.
As for why the forms don't show up, you probably didn't check in the changes to the project file so the new files are not part of the project as it exists in Team Services.
I'm writing a small console tool in C# that needs to know the revision number of an SVN working copy directory to process other data with this number. I already have support for SVN 1.4 to 1.6 by directly reading the entries file in all .svn directories. But SVN 1.7 has changed that to use a single .svn directory with an SQLite database in it.
What's the best method to determine the revision number of a working directory?
I've just tried to use SharpSVN, but it's largely undocumented and I can't figure out how to use it. It's also very huge with 5 MB and potentially several DLLs.
I can't find a simple SVN command line client that is freely downloadable. Also, last time I've seen one, it was huge and consisted of numerous files which is not exactly portable. (It would be great if my tool would only come as a single .exe file.)
Another option would be to use an SQLite library (available as a single separate DLL) and dig into the database myself. I've already done basic research on this but I'm not sure how to detect uncommitted modifications.
TortoiseSVN, which is likely already installed on the machines that will be using my tool, can't be used because it contains everything in a single GUI application, no DLLs that I could reuse.
If you don't want SharpSVN and work with Working Copy, then in 99% host may have SVN CLI-tools.
Check callability of svnversion and call it svnversion <PATH-TO-WC>, intercept output
I use Tortoise SVN's command line tool called 'SubWCRev' for this purpose (http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-subwcrev.html). It allows to determine latest revisions, commit date and more... The drawback of this solution is that this tool work with files, so you will need to define template file and parse tool's output file. This works good for me though.
I am writing a c# winform desktop application that is in contact with a MYSQL database. Of course I cannot leave the database credentials out in the open hard-coded into the application, so where can I store this information so that a nosey customer will have an extremely tough time locating it?
I understand that if someone is very determined to find this information they will most likely do just that, but I want to be able to hide these credentials from the average Joe, leaving me with some peace of mind at the end of the day.
If your answer is to encrypt the credentials, and hard code the encrypted values into the program, please explain which encryption methods to use. Furthermore, where would I store the necessary decryption/encryption keys?
I very much look forward to some interesting responses.
Thank you,

Store it in App.Config File.
Check out above tutorial.
You can also check this good article by Microsoft which teach you how to encrypt and retrieve.

if you have installed Microsoft Enterprise Library, you can easily encrypt/decrypt using its tool as mentioned in this link

Also, after the installation, open the project in studio and right click on the web.config or app.config and you will see the option for the configuration though Enterprise Library. This option is available in Visual Studio 2005 but I cannot see this in Visual Studio 2008 yet. Not sure whether its not compatible with 2008 or I have to follow some installation sequences. I will let you guys know if I come across with any solutions.
This is the link which explains how to work with encryption within studio http://www.pnpguidance.net/Post/EnterpriseLibrary3VisualStudioIntegratedConfigurationEditor.aspx . Read, read & read...
Keep in mind that once you open the .config file you have luxuary of ecrypting each pieces/blocks seperately. Thats the beatuy of it.
For your information I am using Enterprise Library 3.1 which is the latest version and has tonnes of tools that makes your life a breeze. You can download this library at http://msdn2.microsoft.com/en-us/library/aa480453.aspx. Also, look forward for 4.0 at http://www.codeplex.com/entlib
Bottom line you can search google along these lines and I am sure it will give you the whole process.
Hello I recently deleted what I thought was an unused folder which happened to have the solution and code for a windows application I am maintaining.
I have published the app multiple times with ClickOnce and have access to the application manifest, deploy, etc. Is there a way for me to use the published application to get back my solution?
Thanks
If you don't currently use source control, I would highly recommend using one. I'm not aware of a way to get back all the solution files without source control, but you can get back the code using .NET Reflector. There is a file disassembler add-in which allows you to dump the code straight out of Reflector.
not possible. you can't recover the solution and original code from the compiled and deployed version.
if you have not used that machine or hard drive since you deleted it, you may be able to recover the files but it's a long shot and may be expensive.
you need to invest some time in learning source control. git, mercurial, subversion... they're all free and easy to use in windows. having your code in source control would prevent this problem - delete it all you want, just do a checkout from source control again.
Just go get the project back from Subversion.
Basically all you can do at this point is feed the assemblies to a program like reflector and reverse engineer it back. Welcome to sucksville.
If you don't have your stuff in some type of repository already I'd highly recommend fixing that first thing in the morning. With free tools like subversion available, nevermind things like TFS or even VSS there just isnt a good excuse.
Just a quick question:
I'm in the finalizing state of my current C# project, and I'd like to send a version out to people that has 90% of the features initially requested, but it'll be a version of the software that will do all they need - they need the software as soon as possible, basically.
Therefore I'm going to be using the online install option in VS2008 that will use updating to add the final few features, as well as additional things, later. What I'm wondering is the following:
The program will come packaged with a .mdf file. When I create a new version of the program however, I don't want to change all of the data that has been added to the database already. My question is how do I go about doing this?
Thanks!
How are you planning to distribute the update? An installer will have flags indicating when a file should be replaced. (Date, version etc)
One-Click installation has the ability to check for changes on program startup.
