there's a "RemovePreviousVersions" property that you can set to TRUE to take care of that for you.

Hi Russell,
I'm pretty sure the answer you need is in the post from Jimmanuel.
One other thing to keep in mind is, when the user runs the newer installer, with the higher numbered installer version, different product code, and RemovePreviousVersions property set to True, the older version is removed then the new one installed.
If the installer is adding Registry entries or other changes beyond just files, they might get undone. There are properties to control some of these things as well.
Good luck!

That's not the effect I'm seeing here.
I have removepreviousversions set to true I have updated the version number and the product code and I still have 2 entries in add/remove programs

I'm not sure why that would be. I'll give you all the details I can remember from my recent struggle with this issue.
We're using VS 2005 to build the apps and services, written in C# targeting .NET 2.0. The installers are also created with VS 2005. The version scheme I'm using for the product is currently 2.0.4.*. When I have a new build to test, I change the version of the installer from 2.0.400n to 2.0.400n+1. (Unfortunately the installer version is limited to x.x.xxxx rather than the same scheme allowed for the programs.) After I change the installer version number, VS asks me if I want to change the ProductCode. I choose "Yes" keeping my eye on it to make sure it changes. (Always has.)
As discussed earlier, RemovePreviousVersion is set to True. Two other things that I know are involved, which you might want to check, are these. Do not change the UpgradeCode, although it seems like a logical thing to do. Second, the value of DetectNewerInstalledVersion, should be set to True.
(From my mixed-up way of thinking, ProductCode and UpgradeCode should be switched around.)
When the n+1 installer runs, it removes the older files and directories installed by the n installer. It also removes all Registry settings, which is an issue I need to deal with in the future, and it removes its previous entry in the Remove Programs list. The n+1 installer then creates new directories, puts files in them, and adds a few things to the Registry.
Prior to making .msi installers, we were using installers produced by Setup Factory (Version 7.) These .exe installers would simply overwrite existing files on the hard drive with newer ones from its cache of compressed files. I think it's based on the time stamp of the file rather than any version info that may be in the file. I know others have suggested some other alternatives as well.
Hope that helps.

I guess you wanted the ASP.NET forum ?
To do this for the whole page, you need to wrap the page in a control, such as a placeholder, so you can set the properties in the style of that control and all it contains. Same as HTML works.

1. Learn to read, as you are posting it in the wrong forum. Try ASP.NET one instead.
2. Not very hard. But it depends on whether you are using WebControls or HtmlControls, so refer to solution #1 and seek the answer there (with a bit more specific information).

I am creating a serializer for a class that has an array of type Base, but with objects that are actually of type SubClass1, SubClass2, etc. So, that the serializer knows about these subclasses, I load the dll that contains them, extract them into an array and pass them into the XmlSerializer constructor like so:
s = new XmlSerializer( m_ObjToSerialize.GetType(), extraTypes );
Note that the m_ObjToSerialize type is defined in that same dll.
When the constructor is called, it throws the exception:
Unable to generate a temporary class (result=1).
error CS1704: An assembly with the same simple name 'AssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null has already been imported. Try removing one of the references or sign them to enable side-by-side.
As far as I can figure, when the constructor tries to create the temporary class, it loads the dll again . . . why? When I do the same operation with a different dll (with the object and types coming from the same dll), it works. Anybody have any idea what could be causing the difference?

Try signing that assembly and see what happens.
|
|
|
|
|
Actually, I'm embarrassed, but the issue was that I was staticly AND dynamically linking the dll. I would have thought that would have caused a problem right away, but it didn't show up until I created the serializer. All fixed now!
Thank you very much for your help.

The generic ADO.NET classes connect to any ODBC data source.

Right, ODBC if you have a driver. Or a .net connector for it...

It seems IBM has one too, but I didn't want to log into their site.

Is it at all possible to programatically modify the app.config file? I've jumped through all the hoops to add/remove proerties, but when I call the Configuration.Save function, I get this exception:
The configuration file has been changed by another program.
(C:\\Test Apps\\bin\\Debug\\ConsoleApp.EXE.config)
How do I get around that?

Have you looked at this article on reading/writing to App.config[^]? Apparently you can modify it programmatically.
Then again, this MSDN forum post[^] suggests you might have to manually merge some stuff if you've changed the schema.

I forgot I had a library called Nini (it's on sourceforge) that lets me do this with little/no pain.
This whole thing is retarded. One of the most difficult things you could want to do is to go outside of Microsoft's comfortable little world and try something different. .Net sucks.

I think what it comes down to is having something that's tool-generated be modified outside of the tool. Anyways, glad you found a solution.

Not sure, I have done that before modifying the web.config. You sure you dont have that file open in a viewer?

Yeah, it's .Net being retarded. I found a solution involving the Nini library.

Hi,
I have a compiled class library/dll (written in C#) and I need to get a property of an object inside it from another project. Unfortunately, the DLL structure (namespaces and type names) is virtually guarenteed to change AFTER my app has been deployed. So I've been trying to use reflection to get to the object required (having read some settings data like namespaces and type names from a db). At the moment I'm tripping up on the use of System.Reflection.Assembly - it works fine when I reflect on the current project, but when I try to read the DLL I have problems - any help would be appreciated! (Pseudo)Code follows:
public void Main()
{
Console.WriteLine(Foo("MyClassLibrary.DLL", "Person", "Name"));
}
public string Foo(string NameOfAssembly, string TypeName, string PropertyName)
{
Assembly assembly = Assembly.Load(NameOfAssembly);
foreach (Type t in a.GetTypes())
{
if (string.Equals(TypeName, t.Name))
{
type = Type.GetType(TypeName, true);
}
}
object currentObject = GetObject();
PropertyInfo propinfo = currentObject.GetType().GetProperty(PropertyName);
return propinfo.GetValue(currentObject, null).ToString();
}
[Note: We are using our own in-house tools for data access, so the above code has some database stuff removed, and for simplicity try-catch blocks are also removed]
Does anybody have any help they can offer on reflecting on a DLL?
Thanks,
Chris
[Update: Corrected a typo]

Never mind - seems that Assembly.LoadFrom(NameOfAssembly) will do the trick here
Note to self: Check intellisense more carefully!

That's a very bad idea, but DLL versioning should help.

Agreed, but its not my DLL that I'm using. Try as I might the guy writing it won't agree to keep the interface consistant, or even tell me when he makes breaking changes, or comment the code, or ........

Does anyone know if it's possible to get the Win32 handle to the serial port
used under the hood in System.IO.SerialPort?
The reason I want it is so I'd be able to make changes the DCB struct. I
want to set the fRtsControl to RTS_CONTROL_TOGGLE so the RTS signal will be
reset automatically when the TX buffer is empty.
The other option would be to wait for a "tx buffer empty" event to be
signalled after a call to Write. Something like this:
port.RtsEnable = true;
port.Write(buffer, 0, byteCount);
WaitForTxBufferToBeEmpty(port);
this.port.RtsEnable = false;
...but how do I implement WaitForTxBufferToBeEmpty?
