This has already been done for you, take a look at the Form.Owner property.

I have no idea what I just said. But my intentions were sincere.

Hi Everyone,

Some of the .net dlls inh our application has to be shared with some client applications... So we are installing them in GAC , after strong naming them... However we are facing an issue. whenever we are changing the dlls installed in GAC, (We are not version number and snk), we have to rebuild all the application that use this file even id there is not apparent interface change... What are we doing wrong....

Regards
Sabarish

To share a dll, you do not have to install it into the GAC. Have you tried just copying the dll and referencing it in the other application?

As far as referencing assemblies in the GAC, you can click on a reference in your project (whether a reference to a GAC assembly or a non-GAC'd assembly) and specify whether the app requires a specific version.

Does that help?

Hi Judah,

The first otpion does not suite with the client, they do not want any of our dlls where their application is installed.... our will be in 1 folder and theris in another...

The second option we had tried, but the issue is that we have toi change in about 50 project Frown | :(

Well, if it solves your problem, perhaps that is the best bet.

References to strong-named assemblies are bound to that specific version number. There's no other way because there could be multiple versions of the assembly in the GAC.
However, you can redirect the assembly bindings using a publisher policy[^].

Are you doing anything other than scrolling the data? Are you placing data from the grid into other controls to edit them?

Either way, I'd suggest this article here[^] as a good reference.

Problem with using enum in C# interface

Hi,

I'm writing a COM interop interface in C# (VS2005) to be used in VC++, and got into problem of proper exporting enum-s in such interface.

When i previously used C++ for writing COM interfaces, i would just declare the enum within IDL file, and then within the library section also declare it, that way way making my enum accessible when TLB file is imported using #import in C++;

Now in C# if i declare: public enum MyEnymType {val1, val2,...}, then such object when imported into C++ project is declared as: enum MyEnymType {MyEnymType_val1, MyEnymType_val2,...} instead of enum MyEnymType {val1, val2,...}

Is there a way to make C# embed my enum type into the object in such a way that it exports original enum declaration during import instead of such an ugly Type_Value thing?

Thank you,
Vitaly

I don't know enough C++ to give a definite answer, but this is what I think:

I think that each enum value has to be a unique identifier in C++, while in C# they only have to be unique within the enum. That would account for the need of prepending each value with the name of the enum.

This is true, C++ doesn't allow the same enum variables within different enum declarations, but if i'm sure that i have unique variables within my enum, shouldn't there be a way to override for C# compiler to use original names instead for variables within enum? 'Cos this is what i'm looking for, if it is possible....

Just because you're sure that the enums will be unique in your class doesn't guarantee that it will be unique against another class. Here the compiler is trying to protect you from yourself (even though you don't want it to).

And my answer is no. In it's infinite wisdom, MS has decided that you thinking you know best is a bad thing. Hence, my answer above.

Possibly if you use a custom modified version of the mono compiler. Otherwise no.

Deleting nodes recursivily

Gareth H3-Jan-07 23:55

3-Jan-07 23:55

What im trying to do is work my way down a tree style graph and delete each node (not to be confused with a .NET TreeView).

E.g: a user clicks on the top node, and deletes it, from that it should delete every node that is related to that top node. I can delete the nodes that are directly related to the top node, eg the children of that node, but i cant seem to figure out how to delete the children of the children, eg at level 3 onwards.

At the moment, my code gets the selected node, and looks in a dataset and goes through the dataset looking for any rows that match, and then deletes that child node.

Any ideas how i would go about doing this?

Regards,
Gareth.

One way to do this would be to recurse to the bottom nodes and then delete from the bottom up. The pseudo logic would look like this:

function LoopItem(Node parentNode)
{
  for each Node childNode in parentNode
  {
    LoopItem(childNode)
    childNode.Delete
  }
  parentNode.Delete
}

All you would need to do then, is to call LoopItem with the parent node.

Cheers, it seems the key to why my code wasnt working was i was deleting the node then looping, instead of looping and then deleting.

Gareth.
