Remember that VB6 (or older) != VB.NET...er, <> VB.NET!  Completely different runtime.
GetDllClassObject has to be a natively exported function, just like DllRegisterServer, DllUnregisterServer, etc. This isn't possible with the managed compilers, though if you wrote your own compiler you could inject implementations or relocate calls to a bootstrap DLL (this is actually how VB6 and many other executables work - the entry point is actually a redirect to another library that calls back into the PE/COFF executable).

I need to show a drawing surface that is the same size as the default printer page but which is a user control. Then I need to scale it for better viewing. What would be the best approach to take on this one? I am a little bit stymied.
Thanks

Does anyone know how to get the commandline parameters of an externally created process?
The Process class gives you the StartInfo property which includes "Arguments". This works great if I want to start my own process. However, I've found that it never contains the arguments used to start an external process that my program didn't start. It's always empty.
In C, there's a Win32 call for GetCommandLine() which would work great... except it only works for the calling process, not an external one.
SysInternals' "Process Explorer" does this without any trouble for any process so I know it can be done. Any help? I don't care if it's C/C++, VB, VB.NET, or C#.
Thanks

Did you ever figure this out ?
|
|
|
|

Yeah, I ultimately did in C++. I wrote a wrapper in ATL COM so I could easily use it in a C# project I was working on at the time. Unfortunately the hard drive it existed on was lost when the project was shelved a couple years back. I MAY have a backup still on another drive at the office. I can dig that up for you if you really need it, but it will need to wait until Monday. If you can't, then look into examining the PEB (process environment block). I think it had something to do with NtQueryInformationProcess but I'm not sure. You can get the processID of the process you want to query with the .NET classes, then jump into the lower level API calls to get the rest.
Hmmm, maybe there's an actual article in there for CP. I hadn't thought about that before.

It's very tough to get a ready made customizable Grid. What you need to do is, play around with your logic.
I wrote an article on DataGrid formattings. This will help you to customize your figures(numbers) in desided fasion. apart from this please check this link, which contain lot of tips and sample tutorials which will guide you to reach your place.DataGrid Gal

This is a great Windows Forms FAQ and has a few examples of datagrid formatting:

Hi,
I remember that there's an object stream writer in Java which makes it easy to save objects into files. What class is this in C#?

You can use the BinaryWriter, or, for a higher level solution, BinaryFormatter with the [Serializable] attribute on the class.

How i can handle request from client and repond to client in Microsoft IIS 5.0 or more? What do i need? Or some information? Thanks

That's a very generic question. A "request" can mean anything, a web serivce, web page, authentication, ...
You'll have to be MUCH more specific about what you want to do before anyone can help you.

It's like program a windows service that can get the request from user like "username","password" and this service will get some information from internet and send to that user.

You don't need a service for that, just a normal ASP.NET project will work. Still, your requirements are very vague...

Examples of what? You haven't said anything about your app is supposed to do what-so-ever. The only thing you've made clear is that you want to return some data via a web browser. Every web site on the planet does that. At this point, I would suggest picking up a book on ASP.NET/VB.NET and learning the basics of ASP.NET development.

I'm planing a project to administrat a Windows Server.
The project is splited into 3 parts.
User Interface: a Windows application where the Users set all their properties to the Windows Server
Server Manager: a Windows service which manages a database with all setting
Server Admin: to execute the commands given by the Server Manager
the Server Manager has a database with permissions for each user or usergroup, it manages the communcation with the User Interface and the Server Admin.
the Server Admin is needed to execute all command, because some Windows Services, espezialy for the pre-COM-time dont work with .NET and need changes to be put into configuration files.
i.e. Apache
all application communicate over .NET Remoting (binary, not over HTTP)
Now it is nesseccary that the User behind the User Interface has only access to methods and objects, which are for him.
i.e. a user User1 has the right to add a VHost Alias into his part of the Apache-Configaration
where as the Admin has the right to read and write all setting incl. the settings of the user.
so the user has no right to see the ApacheConfigarationClass, only the ApacheVHostConfigartionClass
i thought of a mechanismn to control the right to create an object....
a next problem is to distinguish between 10 or more user logged in...
sorry i'm a newbee in remoting *g*

i'm trying to get a directx form to display as a child form in an mdi. i can't get it to run however. my reasoning behind this is so that i can have a configuration form and a directx windows up at the same time. then when i adjust the vales in the config window it updates the cooresponding values for the directx scene. i just can't get the directx form to keep rendering itself. here's some snippets, i hope you can help me.
when the MDI form loads...
RJSS.frmMain frm1 = new RJSS.frmMain();<br />
frm1.MdiParent = this;<br />
frm1.Show();<br />
<br />
RJSS.frmDD frm2 = new RJSS.frmDD();<br />
frm2.MdiParent = this;<br />
frm2.Show();<br />
declarations in the directx form...
private DD.Device ddDevice;<br />
private O2.SpriteManager sm;<br />
private Open.HighResolutionTimer hrt;<br />
when the directx form loads...
DD.PresentParameters pres = new DD.PresentParameters();<br />
pres.Windowed = true; <br />
pres.SwapEffect = DD.SwapEffect.Discard;<br />
<br />
this.ddDevice = new DD.Device(0, DD.DeviceType.Hardware, this, DD.CreateFlags.SoftwareVertexProcessing, pres);<br />
<br />
this.hrt = new Open.HighResolutionTimer();<br />
this.sm = new O2.SpriteManager();<br />
this is what won't process. if i try to call this function the program just crashes out stating An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll
protected void Render()<br />
{<br />
this.sm.Update(this.hrt.ElapsedTime);<br />
<br />
this.ddDevice.Clear(DD.ClearFlags.Target, Color.Black, 1.0f, 0);<br />
this.ddDevice.BeginScene();<br />
<br />
this.sm.Draw(this.ddDevice);<br />
<br />
this.ddDevice.EndScene();<br />
this.ddDevice.Present();<br />
}<br />
any help is greatly appreciated.
thanks,
Rob Tomson

In vb6 I used a the Heiricial grid control to display data. I have also used it in a few c# projects, but I do not like having to include the extra files in to the installation. Is there a way to use the standard datagrid to do this? The HGrid is easy to use as far as editing a record etc, and I would need the same things from a regular datagrid.
Thanks for your help

I have a windows form, whenever i click the button the app will start calculating. i need to schedule this app run everyday by using windows schedule task tool. The problem is when the app runs, the windows form opened but how i automatic fire button_click event so that the app can be run without my interaction. since sometimes user will need to run this app not at schedule time so i need to keep this button.
I am not sure anybody understand my situation but any suggestion is welcome.
