Using Aspjpeg in C#.Net 3.5 app

[mm2000]

Hi,

Is it possible to use Persits Aspjpeg in C#.Net 3.5? If so, could you please reply with C# code that can use this component?

I used the following code and when I try to load the page I got the error message 'Compiler Error Message: CS0246: The type or namespace name 'ASPJPEGLib' could not be found (are you missing a using directive or an assembly reference?)'.

My Code:

protected void Generate_From_Component()
{

string ImagePath = '../Images/test.jpg';

ASPJPEGLib.IASPJpeg Jpeg = new ASPJPEGLib.ASPJpeg();

...........................
}

Thanks!!

PS: I also tried adding the 'using ASPJPEGLib;' in code behind file at the top and got the namespace reference error message (same as above).

Any help will be appreciated!!

Since aspjpeg is a COM object, you'll need to use a InterOp. I have not tested it but it may work.


You should really consider using ASP.NET component rather than accessing a COM object w/ .NET.

Thanks for the reply Bruce. Few questions on that:

// Since aspjpeg is a COM object, you'll need to use a InterOp. I have not tested it but it may work.

I am not sure what you mean by 'InterOp'? Do you mean change <@Page aspcompat='true' %>. That did not seem to work either.


// You should really consider using ASP.NET component rather than accessing a COM object w/ .NET.

I would also prefer to use .Net component instead of COM object. Which one would you recommend (and is it offered by DASP)? I primarily want to resize uploaded images and found aspjpeg (offered by DASP) to be the best option.

Any help (and maybe code) in using a .NET component to resize image would be greatly appreciated.

Thanks a lot!! http://community.discountasp.net/emoticons/smile.gif

The nearest match I found is in this URL:

but it gives the namespace error message.

I also added aspjpeg.dll to /Bin directory but still get the namespace error message.

InterOp is sort of like a wrapper class for COM object.


For ASP.NET, you can handle graphic resizing by using native .NET classes. See following articles
