Good because FileWebRequest is not appropriate in this context anyway. Use WebRequest.

I used FileWebRequest and WebRequest. But i want to get images from WebBrowser. I want to get image from the session that user is working with. Images are dynamic for users.

I'm creating a website and an application for that. I want to my users use website in a windows app. I created an invisible webbrowser and i send login data from it. When i want to download user's image and other images from site, my site can't recognize user. I want to use images in webbrowser in picturebox or download them with session of webbrowser and then show them.

What's the point of this? You can't simply just display the WebBrowser? Can they access the site without your application? If so, why would they use your app?

If they are offline how do you intend to authenticate and access the webpage to get the images Roll eyes | :rolleyes:

I think you're confused and should stop and think a bit.

1） c# WebClient Object, you can download the image by it.
2) of course, you can copy the image to Clipboard by webBrowser, it's not very good way.

IHTMLDocument2 doc = (IHTMLDocument2)ie.Document.DomDocument;
IHTMLControlRange imgRange;
HTMLBody body = (HTMLBody)doc.body;

Bitmap bmp = null;

foreach (IHTMLImgElement img in doc.images)
{
if (img.src.IndexOf("someinfo") > 0)
{
imgRange = (IHTMLControlRange)body.createControlRange();
imgRange.add((IHTMLControlElement)img);
imgRange.execCommand("Copy", false, null);
bmp = (Bitmap)Clipboard.GetDataObject().GetData(DataFormats.Bitmap);
}
}

if (null != bmp)
{

//deal with the Image
}

I have a multi line text box, wordwrap set to true. No matter what character sequences I place at the end of each line using a hex text editor to build a text file, the text still streams when I loaded the .txt file into the text box. I have tried all combinations of trailing x'0D' x'0A'
Any ideas?
Thanks,

Why are you using a hex editor? Notepad, WordPad or Word will all produce correctly formatted text files with newline sequences in the proper place.

I'm not sure what you mean by this statement, can you explain?

i don't understand your mean clearly.
1)
you should use 'streamwriter' to save to file, 'streamReader' to read from file
, use(Utf-8) Encode.
2)
may be you should consider to change to right ''Hex，Octal，Binary。。。。“ before show to 'multi line text box',
after you read form file.

Access a COM dll without registering it?

DiscoJimmy11-Sep-09 4:38

I have a C# application which uses a COM dll that was registered when some third party software was installed. So when I added a reference to it in visual studio, it naturally created an Interop.dll, and that's what I have a reference to.

My problem is that I wanted to send the program to a friend and he doesn't have that 3rd party software on his machine.

What's the best way to deal with this? I tried adding a reference to the dll file itself instead of using the COM tab, and that seemed to work, but it looks like it involves the path to that file on MY machine, which probably won't work on his side either. Copy Local is set to TRUE, but that seems to just copy in the Interop dll. I've had experience with a setup installer packaging the needed files and registering them for you, but i'd like to avoid an installer. we'll be doing rapid dev-test cycles and it's nice to be able to just 'drop-install' the files on his machine.

Anyone able to guide me on this?

If you send him the com dll just get him to open a cmd prompt and run regsvr32 <path_to_com_dll>.

Yeah, was hoping to avoid that, but it's my fallback plan.

Is that regsrvr32 file part of the visual studio SDK, or the windows SDK? And is it freely available? because i imagine i'll have to get him that as well.

Neither, its part of Windows.

Im not confirm that the regsvr32 is perfect for a dll registration which is developed by using C#.net..RegAsm command can be consider... Smile | :)

Its a COM dll, not a .NET assembly.

RegAsm allows com clients to call .NET dll's. The OP was asking about accessing a COM dll from .NET
