When i import all those function in my application i am able to call functions that are exported using c calling convention but not able to call functions that are exported using c++ calling convention.
any help is greatly appreciated..

I have a scenario similar to the following:
Assume a single assembly (SomeAssembly.dll) contains the following types:
1. Class B inherits from class A
2. Class A implements properties Moe, Larry and Curly, all of type ArrayList.
3. Class B implements a public interface containing all of the public members of both classes A and B.
The problem:
I export the type library for SomeAssembly.dll using
Regasm.exe SomeAssembly.dll /tlb:SomeAssembly.tlb /codebase
When I view the generated type library, I see that while properties Moe and Larry appear as "Moe" and "Larry" (their proper case is preserved), property Curly is exported as "curly" (all lower case). So far, I haven't been able to find an explanation for this behavior, and while the CCW works just fine, the name change is a little disconcerting for my client.
The only similar article I was able to find referenced a known issue whereby if there was another "curly" property that was written to the type library first, all following same-named properties would bear the lowercase name, but there is only one "Curly" property in my assembly.
Any ideas? Failing a solution, is there any attribute decoration I might use to force the proper case in the generated type library?
Thanks.

Hello
just looking for some advice really on how i should go about a project. Any help would be appreciated.
I have an application written in C# which accesses a mysql DB, it basically a reporting system keeps track of who is in work on what day etc. Has some options to print reports etc.
What i need to do is write a small app that can be installed on a seperate computer but uses the methods from the other application. Basically i just want this app to be use the print options on the other application and check whether the other app is currently running (there is a table in the database that has a flag when people are using the DB).
From what i can gather the .Net remoting is the best way to go about this?
Anyone know any smaple apps or good articles on the subject area, or any experinces on this kind of app ?
thanks in advance

What is the general consensus on this idea?
According to the series of videos I have been following on MS about designing class libraries, you really should not throw exceptions in property setters. But, if you don't then how are you to signal the user that you have set a value that is not correct?
For example I have a property that takes a Guid value. Inside the property I want to make sure that the value supplied is a correct Guid (ie: formatting, length, etc...) and I am using regex for that, but if I determine an incorrect value what should be the way I signal the user?

If you don't want to throw an exception, then you have to set a flag or make your whole object go into an indeterminate state. I'd be in favour of throwing an exception, but leaving the object in a 'clean' state, so it can still be used if that's what the client wants.

That's what I am doing now. Just wondering if there is a more preferred method.
I am always looking for better ways of doing things.
Thanks.

I guess the idea behind the suggestion is that users of your class won't be expecting a simple property assignment to throw an exception.
If it's your own codebase, I guess it's fine then. Or, you can always change it to a method.

I am having a bit of a time trying to figure out which assemblies my application would like in order to run.
Actually, I am getting a CLR Debugging Services exception when I try to start the app. I know this happens when I am missing a referenced assembly. So I check the References -all of the DLL's listed there are contained in the GAC or in the application directory. The app of course runs perfectly on my development machine.
So I guess I have two questions.
1. Is there a way to capture in a log file which assembly the app died trying to load? The default "there was an error" message is just about useless.
2. I have looked in the .NET Config - Applications and checked the "Assembly Dependencies" listed under my app when I add it. There are several assemblies that are listed as being required multiple times (i.e. several versions???). I have no idea why this is happening. On my Dev. machine, these are listed only once with one single version. On the other "clean" machine (no VS, etc.) the dependencies show up multiple times - same executable.
How do I actually figure out what is happening here? Any insight on this would be greatly apprecitated.
thanks

This might help.
So might this.
And, if those don't help, try Reflector.

Hi,
My name is Liran, Im working on a project that the server is written in java technology (APACHE TOMCAT) and we considering now to turn the client to windows application instead of web. Our main option is to choose .net c# as our client technology and the connection to the server will be by web services on the server side (the webservices is written in java).
I already made a prototype to check it and it worked really good.
Im trying to get some information about the risks that i need to take into consideration if i choose this option. so if someone already dealt with it ill really appriciate your help.
Best regards,
Liran

Dear all,
The function System.Windows.Forms.Control.GetChildAtPoint(Point pt)
find control reference to the Control's Client Rectangle.
However, I am looking for a Control that is out of screen.
i.e. out of the Client Rectangle, but within the Display Rectangle.
Is there any method for me to get that Control by a Coordinate point?
Many Thanks.

Are you looking to get a control that sits on a different Form?

It is on the same form.
The control hierarchy is like this:
Form
|-Groupbox A
|---TextBox A
|
|-Groupbox B
|---TextBox B
However, the size of the Form can only show the Groupbox A. I have to scroll down in order to show another groupbox.
Now I have the coordinate of Groupbox B and TextBox B, can I get the control TextBox B by its coordinate point when the screen is still showing GroupBox A???
Many Thanks!!

You'll just have to try it. There is a chance that it might not work because it's not visible, and therefore, not being drawn.

Dont install it, just download it and install only the Library and you will have the documentation without using the vs.

i got a problem about WMI.
i want use wmi to config my network adapter, such as ip address, subnet mask, etc. and i found some methods of Win32_NetworkAdapterConfiguration class can do this, but they are all enable method, for example, EnableDNS ,it can enable DNS setting and specify dns search order.
THE PROBLEM is how can i DISABLE DNS search, namely , obtain DNS server automatically.
|
|
|
|
|
Call EnableDHCP. It sets the adapter to get all of its settings, including DNS stuff, from the DHCP server.

Is it possible to make a project use the 1.1 framework instead of 2.0?
Since most people have 1.1 installed by now, but nearly noone has 2.0 I would still like to develop for 1.1 but use VS2005.
