Getting a custom components' parent 2sky29-Jan-04 4:55 2sky 29-Jan-04 4:55  Can anyone help me with this one, I'm all out of ideas I have a custom Component deriving from Component. This component also implements the IListSource interface. The most important method I have to implement for this is GetList(); In the GetList method I need to obtain the parents type where my component is placed on. In this case a standard form derived from System.Windows.Forms.Form. I tried to do the following: IDesignerHost host = Site.Container as System.ComponentModel.Design.IDesignerHost; With the host I have now, I can get the RootComponent, BUT, and now comes the problem, the RootComponent is at that time the baseclass of the actual parent object. So I get System.Windows.Forms.Form instead of my derived parent class' type. I've discovered that this is because the designerhost is at that moment still in the loading state. The problem is that the GetList() is called before the loading state finishes and by the time the host is fully loaded, it it already too late, GetList isn't called again. Can anyone help me with this ?

Just want to ask, is this topic covered by another article in Code Project? I think I came across one - but I didn't read it beacuse I already wrote mine. If there isn't I will send the package to Code Project web master to have it posted here. And no, been working on different stuff. So, as for mdac (question you asked over email), I don't have the answer for ya.

I included a COM reference for Excel Object and used the Excel Application object to read from a spreadsheet. I am assuming this is an unmanaged code. Doesn't .Net have some class similar to this which can allow me to access any cell inside an Excel Sheet? Praveen DrawImage blurs when resizing image Michael Menne28-Jan-04 10:18 Michael Menne 28-Jan-04 10:18  Hello there, I'm quite new to the .NET Framework. At the moment I'm trying to draw an image, actually it's working quite nice. Nevertheless when I draw the image bigger than it normally is, it gets blurred a lot. I guess thats some kind af antialiasing. So does anyone know how to disable this effect? I'm using this code for drawing: g.DrawImage( m_bmpTileSet, rcDest, rcSrc, GraphicsUnit.Pixel ); Thanks, Menne Setting HWND handle to a .NET Windows form MrBean27-Jan-04 22:04 MrBean 27-Jan-04 22:04  I'm developing a .NET based DLL (in VB.NET) which exposes a COM class for an old system which only supports COM/ActiveX. So I'm basicly calling my new .NET COM class from an old VB6 based application. One of the methods in my .NET based COM class takes a HWND handle (long) which is used as the parent handle for a form which my DLL creates and displays. But how do I set the parent handle to my .NET Windows form ? The form is displayed with the Show method (modeless). Re: Setting HWND handle to a .NET Windows form Serge Lobko-Lobanovsky27-Jan-04 22:35 Serge Lobko-Lobanovsky 27-Jan-04 22:35  let me ask why do you need to pass a HWND? i am not sure if it is possible. Regards, Serge (Logic Software) Re: Setting HWND handle to a .NET Windows form MrBean27-Jan-04 22:39 MrBean 27-Jan-04 22:39  Because the old system that will use my .NET component and form, only supports a win32 HWND... Re: Setting HWND handle to a .NET Windows form Serge Lobko-Lobanovsky27-Jan-04 23:10 Serge Lobko-Lobanovsky 27-Jan-04 23:10  i mean, why do u need a parent HWND, for what purpose? Regards, Serge (Logic Software) Re: Setting HWND handle to a .NET Windows form MrBean27-Jan-04 23:45 MrBean 27-Jan-04 23:45  My .NET form need the HWND handle because it's an child form within another application.

Re: Setting HWND handle to a .NET Windows form Duncan Edwards Jones28-Jan-04 5:23 Duncan Edwards Jones 28-Jan-04 5:23  Then you will need the SetParent API call...and pass it the handle you get as per the earlier post.

Both this... m_MyForm = new MyForm SetParent(m_MyForm.Handle.ToInt32, m_ParentHandle) m_MyForm.Show() ...and... m_MyForm = new MyForm m_MyForm.Show() SetParent(m_MyForm.Handle.ToInt32, m_ParentHandle) ...doesn't work... something else I need to call or set ?

Regards, Serge (Logic Software) Re: Setting HWND handle to a .NET Windows form MrBean28-Jan-04 3:15 MrBean 28-Jan-04 3:15  So in short (regardless if it's a MDI child or not)... I can't ;( I think I have given enough info... but can can try to write it different I'm making a .NET DLL which contains a single Windows Form. This form is used by an VB6 based application thru COM. The VB6-based application then use my DLL/form by calling a few standard methods and setting the form size, parent handle and such. It's the application way of supporting plug-ins. The plug-ins are shown as kind of controls on a form but not as a MDI form or ActiveX control - it's a kind of embedded form. This works today but only with VB6 DLLs (COM) and VB6 forms. So I basicly need to make a plug-in for the application but this time in .NET...
