Hi,
I have a question about deployment project in C#. When we compile our project in c#. It generates two files one is perhaps setup and other is some thing called bootstrapper file. Now i want to know which of these two files is to be given to the user. I want the installer to install .Net and SQL Express if it is not installed on his machine already.

Thanks in advance...

Firts one I'm not sure.

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[^].

I have a main form that is set to auto scroll so that when lower screen resoloutions are used, scroll bars are provided. The controls are not getting set back to position 0,0 but are displaying where ever the last scroll bar displayed the previouse control. Any way to get the controls to reset to display back at 0,0 and the bottom scroll bar to reset back to the left and the right one back to the top?

Initializing dictionary with a struct? help pls

Hi guys what is wrong with this line? lookupObject is a struct. I just want to initialize the dictionary with the struct as value.

public static Dictionary<string, lookupojbect=""> dicTextLookup = new Dictionary<string, lookupojbect="">();

this is the error: "Error 1 Inconsistent accessibility: field type 'System.Collections.Generic.Dictionary<string,lookupojbect>' is less accessible than field 'dicTextLookup' C:\IL\TranslationController.cs 44"

Thanks

Could you repost that snippet, but check the "Ignore HTML tags in this message" checkbox when posting? We can't see your full code otherwise.

Is dicTextLookup non-public? Are you exposing the field as public? This error typically occurs if you're trying to expose some private/protected/internal thing as public. For instance

private class MyFoo {}

public class MyBar()
{
    public MyFoo instance; // Error: inconsistent visibility: MyFoo is private, yet we're trying to expose the field as public
}
