It screws up because controls are not registered on a per-application basis. Controls are registered using the COM GUIDs in the controls and the registration is stand-alone. The controls can be used in any application anywhere.
If you have multiple copies of the same control, the control is only registered ONCE since each copy has the same GUIDs and CLSIDs. The filepath to the control is also part of the registration. So, if you have an application that uses the same controls as another application and your installer, when uninstalled, removes the registration details when it removes the controls, the registration data is destroyed for the control no matter how many copies of it are on the machine.
The problem comes down to how your installer is built. The Setup project that comes in Visual Studio is a barebones installer that doesn't have a ton of features in it and can do some pretty stupid things. If you trust it implicitly, without knowing how it's doing things or why, problems like your will come up.
I highly recommend studying Windows Installer technology (specifically Shared Components and reference counting) and using a 3rd party packaging solution, like InstallShield, InnoSetup, Advanced Installer or WiX if you want to avoid situations like this in the future.

If figured as much but we have been uninstalling and re-installing VB.Net apps for years.
Currently the program the started this is still having problems.
Each time I start the IDE for this VS 2010 or re-open this solution has most of it's depencies refrences are not found.
Errors
Unable to find source file N:\accnt\code\program... for
scrrun.dll, mscomct2.ocx, Interop.Scripting.dll, Interop.MSCOMctl2.dll, Interop.Excel.dll, Excel9.OLB, AxInterop.MSComctl2.dll. (in Solutuions
If I refresh dependencies then errors go away until the next start re-opening of this solution even if I save the solution.
This does not happen on the VB2008 projects even for those using the same components/references.
How do I fix this?

Try Save and Close your project, then go out to the project folder and delete the *.SUO files. You'll have to enable viewing hidden files in Explorer to see it. Then reopen your project and see what happens.

Thanks. Now I know where that stuff is. It took care of it. Thanks

In researching this it seems that the problem even exists with the 3rd party installers unless a lot of work is done first.
So if a lot of work must be done why not just do it with the VS.Net Deploy and Setup project, etc. instead of learning another component.
But it is not clear where to look for the proper documentation to know what to do.
We if have a vb.project that has 30 screens with code behind and another 40 or so modules it is a bit tough to know what to do.
Is the solution in the references or the setup dependencies, etc.?
I've seen discussions of have different dlls which is unclear how to do it with the vb components and ocx modules, etc. both for MS VS stuff and also other SDKs, etc that we are using. I don't think that renaming DLLs will work.
So where to begin? What is the best practises for setup and deployment?
This has been causing us nightmares and we are ready to bit the bullet if we knew where the bullet was.

The reason you're in this position is because you don't understand how Windows Installer works. So you're going to have to learn this no matter what.

Because you have no choice. The Deployment and Setup project no longer exists in Visual Studio 11 and it's capabilities are very limited to begin with. You have to use a 3rd party tool, such as InstallShield LE, or InnoSetup, or AdvancedInstaller, ...
Either way, you're looking at a bunch of work to DO IT CORRECTLY IN THE FIRST PLACE!

The number of forms you have in your application has no bearing on the installer at all. The complicated part comes in when you start referencing external components and libraries. You have to KNOW what you're referencing, how they works and what their installation requirements are.
Coming up with an installer is not just a "OK my app is done now throw an installer together" process. Installers are another program you write SIDE-BY-SIDE with your application so that the installer knows what your app is using and how to correctly install every file, in every component, in every feature, what merge modules are, why they exist and how to use them, ...

No, it won't.

You're writing application in the dark. You have no idea how the components in your app fit together nor how external libraries work, how they are registered or why, and how your installer has to handle these things. If you don't know these things, you can't just throw files anywhere you like and expect everything to work fine.

Dave, you have said a lot about how we are doing in wrong, etc. but nothing about were we can get the documenation on how to do it right which is what was asked.

"Use a zip file and change the extension"
That does not help you? That is quite a common way nowadays.
Ever tried it the other way round, with say a .docx? Do that! Rename a Word document to a zip file, and unzip it!

That's no way to introduce yourself. You got the same type of brain that I have, and you probably run on water and sunlight like the rest of us.
Use a database (like SQL CE or SQLite), encrypt the contents and rename the extension to ".dat". Use a folder, zip it and rename the zipfile to ".dat". Use an Xml file, and store the other files in Base64-encoding, and rename it to ".dat".
Let's start simple; can you post the code here to write the line "Hello world" to a file? If not, that's where to start

If you want to do it through your own code, use a FileStream to read the files into memory and another to write them to the same file. FileStreams read the raw bytes of the files. You'll want to put some sort of delimiter between the files so you can separate them later. To add your delimiter to the file, create a string and then use System.Text.Encoding.Ascii.GetBytes(YourStringVariable). That will give you a byte array with which to write with the filestream's write method.
Hope that wasn't too confusing!

PS: If you want to compress your files, there are lots of examples for compressing files in .NET, just search google for "compression vb.net"

I have a question about how to do the following and the pros and cons about doing either.
I have a class that I want to be able to log some activities, such as "function has been called". I could define an event call CurrentInfo(byval infoType as Integer,byval message as String), and then let the logger subscribe to the event and do whatever, or I can pass a logger to the class and whenever I wanted to log something I will call "logger.log(infoType, message)"
Which appoarch is better?
Thanks

instantmaker wrote: Which appoarch is better?
That depends on your definition of "better". I'm using an ILogger, sometimes writing to console, sometimes to the eventlog, and a null-implementation of the ILogger (doesn't log anything). The logger-object is static, so it doesn't need to be passed as a parameter to each and every method.
Might not be the "best" approach, but works for me

Thanks for the answer. I know it's relative and is different from one to the other scenarios. I found that, as you said, if I don't need a logger from time to time I will have to pass a null logger to the class. Yet event can be hooked up dynamically as needed.....I really want to know is there a big PLUS to use logger instead of using events. Thanks

instantmaker wrote: I will have to pass a null logger to the class
You don't have to, you could also test whether the user has a boolean checked to control if the app logs or not. The null-logger a common pattern because it's convenient.
instantmaker wrote: I really want to know is there a big PLUS to use logger instead of using events.
Requires less code. How would you do it with events? Raising an event for everything that you might want to log? Can you post an example?

I was woundering if anyone knows any codes for a Rehash and Resign Program? It might have.... 2 buttons or 3 if it will have rehash and resign as one button then rehash as a button and resign as a button.
it should have atleast 5 textboxes ....
|

|

You seem to want to modify a saved game then re-hash it?
No, you're not going to get any help with that here. I think the reasons are quite obvious.

Thanks Anyways Figured i would still give it a try to ask about it on here.
I've Figured it out after a few hours plus using my Visual Basic Guides as help but the code words on First use then Gives me an Error .... so i set the Program to Restart so as to NOT get the error but if anyone can help with THAT it would be GREAT  Thanks anyone who can help if you need that part of the Code just ask and ill give.
Im NOT going to Delete that part of Code to NOT get the errors....

OK. What guides are you talking about??

Still not a clue what you're talking about.
Member 8768189 wrote: so i set the Program to Restart
Since there's no property or method to "restart" an application, we STILL don't have a clue what you're talking about.
Member 8768189 wrote: so as to NOT get the error
You never said WHAT error you got, not what the code looked like, so, uhhhh, yeah, more of the same "we don't have a clue what your talking about"...
Member 8768189 wrote: Im NOT going to Delete that part of Code to NOT get the errors....
WHAT code?? That does WHAT?? Again, you haven't provided us the smallest of clues to figure out what you're talking about...
