the easy way to do this is to add an instance variable of the WebBrowser class and let it execute a page containing the JavaScript. See the sample code for WebBrowser.ObjectForScripting on MSDN:
WebBrowser.ObjectForScripting
This method works fine as long as you can host the WebBrowser control inside a form in your application. Regarding the packaging of your plugins, personally I like the widget concept (as I have to deal with it on a daily basis for a project I am working on). A widget is basically a ZIP file with a certain structure and a manifest file. The manifest file (called config.xml if you follow the w3c standards) points to the main HTML file to execute.
Let me know if you need more help or want more thoughts regarding this.
Cheers,
Marcelo

Hi,
ok many thanks, but is it possible not to work with the WebBrowser-Object? Maybe with HTMLDocument or an other System like WebKit or else? And is it maybe possible to start events from a object in the HTML from my code? I mean, if i click a button in my Application, i want that the HTML-Page is running a specified js-function.
|

|
|
Another idea!...
is it possible to embed the javascript-files, classes and so on into my own project? i mean, that they use my classes and functions and i can use their functions, classes, objects and so on?

i'm trying to open an existing excel worksheet. my code is:
Microsoft.Office.Interop.Excel.Application excelApp;
Microsoft.Office.Interop.Excel.Workbook excelWorkbook;
Microsoft.Office.Interop.Excel.Worksheet ExlWrkSheet;
private object Opt = Type.Missing
excelApp = new ApplicationClass();
excelWorkbook = excelApp.Workbooks.Open("..//..//Data.xls", Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt, Opt);
on the last line i get an exception that he cannot find the file.
i placed the file in the project directory.
i tried also "Data.exl" path when the file is placed in the debug directory, it didn't helped.
what am i doing wrong ?

Since you have relative path, based on the path, you have to place the excel file two folders above the location where your program starts. You could try using an absolute path first to see that it works and then change the path to relative.
|
|
|
|
|
i tried it with path "c:\\Data.exl" and it works.
for some reason he doesn't recognize relative path.
|
|
|
|
|
Actually what I wrote previously is not quite correct since the relative path is evaluated by Excel so it depends where the excel starts from. Sorry about that.
What you could do is that you use absolute paths in the parameter you pass to the Excel, but if you want the path to be relative from your application point of view, you can use for example Assembly.GetExecutingAssembly and get the location of your application from there. After that you would modify the path the way you want.

It does recognize relative paths and they are relative to the "current directory". The problem is you cannot reliably control, nor assume, what the current directory is. Just launching the .EXE from a folder does not make that folder the current directory. It could be anything. So, knowing that, best practice is to always use fully qualified path names to the files you're working with. Also, the forward slash character, "/", is reserved for command line switches, even though it does work for paths, this can cause you problems that are hard to trace down in future projects. Back slashes, "\", are reserved for path specifications.

Hi,
in C# string literals a backslash is an escape character, causing the next character to be interpreted in a special way, and a double backslash results in a single one. You never should use double forward slashes though.

Hello,
I am trying to send to Babylon a word and to preform a copyall there.
I have used the following code taken from sendkeys article in this site:
int windowHandle = Win32.FindWindow(null, "Babylon");
Win32.SetForegroundWindow(windowHandle);
Win32.SetActiveWindow(windowHandle);
System.Windows.Forms.SendKeys.Send(_word);
System.Windows.Forms.SendKeys.SendWait("{ENTER}");
System.Windows.Forms.SendKeys.SendWait("{TAB}");
System.Windows.Forms.SendKeys.SendWait("^A");
System.Windows.Forms.SendKeys.Send("^C");
Now the SetForegroundWindow doesn't work on Babylon(It workes on every other thing I try to use on).
Also after TABBING the ctrl+a and ctrl+c doesn't work....
could someone help me somehow?

Hi All!  I have posted a fe questions, read many tutorials, and doco's, have been on MSDN and Google, and have found absolutely zero support for the task I am trying to accomplish. I am simply trying to find every URL that is found in a plain text file, but it seems almost impossible to do since every sample I have tried, including my own code, does not work. It either brings up too many errors, or just never finds anything. Or both sometimes. Does anybody know of any reliable sources that could simply explain how one would go about finding all URL's inside a text file and saving those URL's to a new file each on a separate line, wether it is using Regex or something else? Any help would be appreciated. Thanks
Regards,
jay.

Hi
As far as I know you can use regular expressions to find different patterns in a text. I think you should find one or more suitable regex patterns for the task you want to accomplish.
May be you should take a look at
some regex libraries[^]

thank you for the link i will check it out now
j.t.

Regular expressions are hard to write and very powerful once you get it to work.
Start with some simple pattern so that you get a result, like finding every occurance of the string "http://" in the text. Then you can refine the pattern to find exactly what you want.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
You can also try using Expresso[^] and see if that helps at all.
Why is common sense not common?

Thanks everyone for your answers i checked out the regex libs and quickly ran away from there lol... but then i checked out expresso, looks really cool it's still downloading, i can't wait to use it! thanks everyone  Here's an idea... If our brains consisted of computer chips, wouldn't it be cool if all we had to do to learn something new was to insert a tiny memory chip into our ears which stores all the learning material on it? Then if we needed to recall information, we can just use our minds to search thru directories and subdirectories to find the file in our mind that has our info? lol

hello everyone..
Good evening.. )

<br />
float fltZoomF = 1;<br />

gPanel2Graphics.Clip = new Region(Panel1.ClientRectangle);
gPanel2Graphics.ScaleTransform(fltZoomF, 1F);
</pre><br />
<br />
if i run my application the sine wave fits correctly to the screen size,<br />
but if i try to zoom by increaseing the fltZoomF value to 2..<br />
<br />
how much pixel or percentage it ll going to increase the width of the graph..<br />
<br />
im using horizontal scrollbar to scroll, how do i proceed to increase the ScrollBar maximum value while the fltZoomF is changed to 2.<br />

I want to remove the Control Box of a child Form ( you see it below the MDIForm control box) Control box is the minimize, maximize close bouton on top right corner.
Look at this ScreenShot[^]">
|
|
|
|
|
AFAIK, you can't remove it. It's the TitleBar of the MDIChild form when the child is maximized.
|
|
|
|
|
Thanks Dave,
Can we merge the title bar of parent and child, so that only one title bar is visible?
Regards,
Karmendra

No, it's not supported by the standard MDI library in .NET. I don't know of a library that does this.
