Re: How do I use try and catch

What I do is catch the error and write it to a custom eventlog.

I created a class that takes a string value(error.ToString()) and the type(error, warning, info).

Then in my catch I call the class with the parameters to write the eventlogentry and then just display a pretty message to the user.

You can do the same principle, except for a class that writes the an custom eventlog create a class that writes to a txt file.

Have a look at log4net[^]. It should cover (almost) anything you need regarding any kind of logging.

office 2003 interop application without office 2003 installed

Hi All,
Can anyone please tell me if there's a way to use a .net application that
makes use of office 2003 interop assemblies on a server machine that does not
have office 2003 installed. The applcation creates .ppt files and there's no need
to actually view them on the server, so we don't need office 2003. On the other hand
the com components that the interop assemblies interface to are missing on the server.
Is there a manual way to copy the office com components and register them on the server?

Thanks very much

Even if it could be possible to find out which dlls are required to instantiate and operate the objects you want to use, I doubt that the office EULA will cover that.

Second one, on the properties of your installer theres an option removePreviousVersions. Just set that to true

I have the exact same problem. You can't use the installer within visual studio as it does not allow for multiple installation simultaniously.

So I started looking at external installers. Nice one to try is nullsoft installer, its freeware, you can be even include stuff like the runtime enviroment. You will just need to learn a bit about scripting so that you can manipulate the installer scripts as to what install when. They have alot of documentation and examples, so run through them, might even be able to mod one of the examples.

Add the merge module of MSDE with your application. The merge module for module for MSDE is available with SQL Server in one of its subdirectory but exactly which one, i am not sure. But i think its extension is .msm . You can add that merge module to you application. So when your application installs, it will also be installed along with it.

Installer custom action

27-Jul-06 20:47

Hi. I need help. When you assign the CustomActionData you do the following.

/textValueA=[EDITA1] /textValueB=[EDITA2]

The problem being that when the user enteres a two word value in EDITA1 it soesn't take the whole string as the value, it takes the first word as the value and uses the space between the firts and second word as the delim.

Is there some way that I can change the delim between
/textValueA=[EDITA1]?/textValueB=[EDITA2]

Thanks in advance

Glad you found out how to encapsulate these arguments. Smile | :)

You have to be careful, though, if you want to give a path as an argument.
Something like

/instPath="[TARGETDIR]"

will give you a very strange error message (I think I remember something about the last " being escaped by the last backslash in the path or something similar).
You have to use

/instPath="[TARGETDIR]\"

instead.

Thanks, will keep in mind, currently it's only getting the client details, Company name etc..

I know if you use the installer helper class, you can reference the installation path with

path = Context.Parameters["assemblypath"]

Problem is that it returns the whole installation path including the executable. eg

C:\Program Files\Test\Test1.exe

what I want is just the

C:\Program Files\Test\

Any Ideas???

Thanx

Well that's simple: Just use Path.GetDirectoryName() to get only the directory.

Take a look at the NSIS project[^]. Its an easy-to-learn and in my opinion very useful open source system for creation of Windows installers. Among many others the web site provides a code example for Installing the Microsoft .NET Framework[^].
