How do I create a DLL with C# I have searched google and codeproject, but they both find articles that just say "DLL" once in the article(that is what i cearch engine does).
Thanks for any and all help!

In the project property either use class library or use the class library template while opening a new project.

Create a Class Library project. This will create a .NET Framework Assembly though. C#, or any other Managed language, can't make a .DLL that exports library functions like C++ can. The .NET Framework doesn't support C-style exports.

So how do I use the files I create, any references, and thanks that will help a lot.
|
|
|
|
|
You Can use them by adding a reference to your DLL.
Thanks and Regards

Yes, the project will create a .dll file when being referenced.

There are two ways that your class library can be used:
1) The 'safest' way is to create your class library project/solution, write your code, compile it as a dll, then copy that into the /obj directory of any project that will use it. Then add reference, browse to the obj directory and add a using statement for your library namespace.
2) You add the class library project to the solution that will consume your project. This is only best if this is the only solution that would use that class library. In this method you would do an Add Reference, click the Project tab, then select your class library project and add it.
It is highly suggested that you modify your AssemblyInfo.cs file and make the version number something like "1.0.0". This way you control the version number of your dll with each release. Otherwise you create a new copy of your dll even if it is a minor implementation change.

In my database I have my primary key automatically assigned (it's a PO number). In my app if I cancel a new row insert then add a new row....it will keep reassigning a new pkey. However when I update the datasource it gives it hte proper p-key.....how can I get the cm to show the right key all the time?
Thanks

I can implement MC++ interfaces in many other C# projects but not in my addin project, the error is: COM interop can not find a type library for the C++ interface project.
Anyone knows why this happend?

and a poor question: how can I do this?---"compile with: /clr".
|
|
|
|
|
Is the C++ code native? Are you using MC++ (.NET Framework 1.1) or C++/CLI (.NET Framework 2.0)?
|
|
|
|
|
MC++ like this:
__gc __interface IA
{
}

Hello,
I'm trying to int.Parse a percentage value. Using the NumberStyles parameter I can parse a currency value with currency sign and commas and everything, but there's no enumeration item for percentages. Looking into NumberFormatInfo, I can see that the percentage sign can vary between cultures.
Does anyone know of the good way to parse a percentage string? I don't want to just remove the sign at the end (that seems dirty  )
Thanks!

I am working on this project, when I add items to a drop down list using a list item it wont into the event handler on selectedindexchanged. However, use the other definition for the dropdown to add in items via a string, it actually goes into the event handler on selected index changed, for example when I do this:
<br />
ListItem item = new ListItem("One","1");<br />
DropDownList1 = new DropDownList();<br />
DropDownList1.Items.Add(item);<br />
<br />
it will add it in, but when I select something different it wont go into the event handler, but when I do this:
<br />
<br />
DropDownList1 = new DropDownList();<br />
DropDownList1.Items.Add("One");<br />
it will go into the event handler. I dont understand why this is.

Make sure "AutoPostBack" is set to "true" and the "SelectedIndexChange" event is actually pointing to your event handler before testing your application. Sometimes when you move or modify your control, it resets everything back to its default settings. Also, unless you are creating a DropDownList dynamically, don't initialize it. This action will also reset it back to its original default settings.

Hi George, thanks for replying to me. I did all of that already, they are dynamic, I don't understand why it wont work. Have you tried it both ways, I dont know if it's teh IDE or what. Im using .NET 2003 though.
|
|
|
|
|
Anyways, I was able to work around it, I had to basically re-engineer everything I did, and use the second definition using strings instead of ListItems in the DropDownList. Thanks for everything.
Sincerely,

Hello

Thanks,

Hi gjsantana,
According to my knowledge what you will have to do, you will make a new Directory Sercher Object and send a different group name in connection string e.g.
private DirectorySearcher DS = new DirectorySearcher
("LDAP://cn=users,dc=servername,dc=domainname,dc=com");
Where it says "users", change it to your desired group.
I hope it helps

I've written a gui app that instantiates objects at runtime, each in its own thread. I've added an eventhandler for each like this:
ADXVoice1.IncomingCall += new ADXVoiceLib._IADXVoiceEvents_IncomingCallEventHandler(OnIncomingCall);
Everything works fine there. But now I've changed this app to be a service. I've got about a million lines that write to the event log (for now) to make sure that I'm actually getting through all the code correctly and everything seems to be going ok. Except the event NEVER FIRES!!
through googling, I've read some stuff about events not firing because services don't have message pumps. Is there any way for me to 'make' a message pump so that these objects will get their events?
thanks in advance!!!

well how else can I get my objects to receive events. Will you ask 'those programmers' this for me?
BTW, I tried the application.run thingy and it still didn't seem to work.

The Application.Run() call did work. The problem was that I was calling it in the main thread. Each object I create in its own thread, so once i put it in there, it works great!! thanks

Hi, I am getting a strange error periodically while working on a Win Form. This error occurs irregularly for strange reason.
Following :
One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.
The type 'myProjectName.myDataSet' has no field named 'DataSetName'.
Hide Edit
at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.Error(IDesignerSerializationManager manager, String exceptionText, String helpLink)
at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAssignStatement(IDesignerSerializationManager manager, CodeAssignStatement statement)
at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement(IDesignerSerializationManager manager, CodeStatement statement)
Now When I click Edit link, I see following code in MainForm.designer.cs
// myDataSet
//
this.myDataSet.DataSetName = "myDataSet";
this.myDataSet.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;
Now, When I delete these mentioned lines, I get back the form regular again. And I dont know how the mentioned code generated by designer after a while which is causing the error. Can u give me any idea please !
