One more query,

I used set MyProcessor = CreateObject("Processor.myProcessor")
MyProcessor.SetValue

but it is giving another error "ActiveX can't create the object 'Processor.myProcessor'"

It seems like The dll is not registered as ActiveX Object.
What I did was in the project properties -> Build -> Output, I checked the option register for COM interop
and in Project properties -> Application -> Assembly Information -> Make assemble visible is too checked.

What else i have to do to register this dll.

Please note regsvr32 wont work as it is saying could not find the entry point.

Please advise

With Regards,

Hi!

Deep under the "Visual Studio" part of the documentation there is a chapter named "Exposing .NET Framework Components to COM" (under ".NET Framework Development...", ".NET Framework Advanced Development", "Interoperability", "Interoperating with Unmanaged Code"). You will find your options there, under "Registering Assemblies with COM". Or google that for the MSDN location of the piece.

The tool you use (corresponds to regsvr32) is regasm. The other settings you have made should cover the rest of what is needed. Additionally, you can use the ClassInterface, ProgId and Guid attributes on your class if you want to override the defaults (look them up in the docs). As long as you only call your component via late binding (using COM, that is), you needn't worry about versioning (script engines are by definition late bound).

Hope this helped.

in VB version it is not a COM dll

I am pretty sure that it is, otherwise VBScript can not use it.

A COM dll is also commonly known as an ActiveX dll. (This statement may not be totally accurate in every aspect, but for your purpose they are interchangeable.)

Despite everything, the person most likely to be fooling you next is yourself.

You are correct it is an ActiveX dll. But how can I make use of the same functionality in C#.Net dlls. In the previous mail I mentioned some ways I used and also It is going with a installable and the files will be installed to C:\Program Files\MyPath\ and not to System32 as VB version did. Is that a problem?

Thanks Buddies. It worked fine. I went in the same way I said. creating the dll as COM interop and as a visible assembly and it worked fine without using CreatObject too.

1. Get a snapshot of the screen using Graphics.CopyFromScreen()
2. Find the coordinates of the RichTextBox on the screen using PointToScreen()
3. Copy the corresponding portion of the screen snapshot onto your bitmap.

Panel1.Dock = DockStyle.None ' If Panel Dockstyle is in Fill mode
Panel1.Width = 5000 ' Original Size without scrollbar
Panel1.Height = 5000 ' Original Size without scrollbar

Dim bmp As New Bitmap(Me.Panel1.Width, Me.Panel1.Height)
Me.Panel1.DrawToBitmap(bmp, New Rectangle(0, 0, Me.Panel1.Width, Me.Panel1.Height))
'Me.Panel1.DrawToBitmap(bmp, Panel1.ClientRectangle)
bmp.Save("C:\panel.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

Panel1.Dock = DockStyle.Fill

**Note:** Its working fine

I have no idea for printing but I think it will be useful to you

I want to export my tree view data into different format like -
- PDF
- tiff
- Word
- Html
- Excel
using C#..
If anyone know anything it will be appreciable ..
Thanks in advance.. Roll eyes | :rolleyes:

Are you sure you know what you really want here? tiff is an image format, how would you show a tree view in pdf/word/excel? In html you would probably want a mixture of text and images.

I think you need to redefine what you are trying to achieve.

hey Bob,
I have a tree control and the data which displayed in that tree control I need to Export into "Pdf, tiff, Html, Word and Excel"...
I think this will clear my question to you...

Ashfield22-May-08 2:04

Well, there is no simple answer. All of these formats require significant coding which you will need to research individually. Writing to MS applications is relatively simple, writing to HTML is just a case of putting the applicable tags around your data etc.

I think Google is about to become your new best friend Smile | :)

You can do this using reporting services. But you will need to get the data from database using query representing your tree view.

Thanks

Exactly HOW are you meant to export as tiff... ?

Ok, I understand you CAN draw the text onto the image... But you won't be able to IMPORT it without some Text Recognition Software...

http://en.wikipedia.org/wiki/TIFF[^]

"Tagged Image File Format (abbreviated TIFF) is a file format for storing images, including photographs and line art."
