This may come as a surprise, however a Word document is not a text file; it is a complex file that, to all intents and purposes, contains text, but also graphics and images, formatting, page layout information, table of contents, headers and footers, foot notes, possibly revision information, and lots more. You can't concatenate two of those, only a very Word-savvy user can, and he would have to make some tough choices while doing so.

When you say merged, what do you mean? Do you just want the documents appended to each other? What I would do, if I were you, would be to use word automation to open abc.doc and then the other two files; use select all and copy from the other two documents, and move to end and paste in abc.doc.

hi
Can u please tell me the real life example for the begin init and end init utilization in datatable and in which situation it should be used.
Thanks

If you want to change multiple properties of the DataView object but don’t want the changes to affect the data visible through the DataView until you’ve changed all of the desired properties, you can use the BeginInit and EndInit methods.
For example, say you have a DataView bound to a particular DataTable and you’ve also set the DataView object’s RowFilter property so that only a small fraction of the rows are visible through the DataView. You’re displaying the contents of the DataView on a Windows form using a DataGrid, and based on input from the user you want to change the settings of the DataView object’s Table and RowFilter properties. In this situation, you should enclose the code that changes the DataView object’s properties within calls to the DataView object’s BeginInit and EndInit property to prevent the DataGrid from momentarily displaying all rows from the new DataTable.

I have a piece of code that reads an Arabic http link and copies the html body text to a text file. While debugging, I can see that the arabic text is being read correctly (I see arabic characters) but the output file contains weird characters. Can someone point out to me what I am doing wrong here? Here is relevant part of the code:
public string GetWebText()
{
byte[] data;
mshtml.HTMLDocumentClass ms;
string strHTML;
mshtml.IHTMLDocument2 objMyDoc;
string innerText;
TextWriter tw;
FileInfo fi;
int count = 0;
Encoding curEncoding = Encoding.GetEncoding(1256);
string htmlEncodingString = null;
CookiedWebClient wc = new CookiedWebClient();
fileName = path + curLangStr +".txt";
FileStream ostrm = new FileStream(fileName, FileMode.Create, FileAccess.Write);
tw = new StreamWriter(ostrm, curEncoding);
int j = 0;
try
{
data = wc.DownloadData("http://www.alarabonline.org");
ms = new mshtml.HTMLDocumentClass();
strHTML = curEncoding.GetString(data);
objMyDoc = (mshtml.IHTMLDocument2)ms;
objMyDoc.write(strHTML);
innerText = objMyDoc.body.innerText;
tw.Write(innerText);
}
}
catch (Exception e)
{
Console.WriteLine("Exception message: " + e.Message +" url["+j+"] : "+urlArray[j]);
}
finally
{
tw.Close();
wc.Dispose();
}
return "";
}

I'm not seeing things well here, you really should show formatted code, using PRE tags. However it seems
Meneedhelp wrote: objMyDoc.write(strHTML);
is not taking any encoding into account.
|
|
|
|
|
I am not sure I understand.
objMyDoc is mshtml.IHTMLDocument2 object which I am using to extract the body of the HTML text. This text is saved in the string "innerText". It appears correctly to this point. But when I write this text to a .txt file, the text file contains garbled characters.

I'm not sure what you are attempting with CookiedWebClient and HTMLDocumentClass. I would suggest you try replacing
data = wc.DownloadData("http://www.alarabonline.org");
ms = new mshtml.HTMLDocumentClass();
strHTML = curEncoding.GetString(data);
objMyDoc = (mshtml.IHTMLDocument2)ms;
objMyDoc.write(strHTML);
innerText = objMyDoc.body.innerText;
tw.Write(innerText);
by
data = wc.DownloadData("http://www.alarabonline.org");
strHTML = curEncoding.GetString(data);
tw.Write(strHTML);
to see how that works out. I expect it will handle Arabic text well.
I am puzzled by you casting an HTMLDocumentClass to IHTMLDocument2; and by the compiler accepting your objMyDoc.write(strHTML) statement, as write expects an array of BSTR, not a string.
I would suggest you try and solve your functional requirement based on System.Windows.Form.HtmlDocument

And how exactly did you 'see' those characters?
In other words you used something to view that file. What did you use? And how did you validate that that method would display the characters correctly in the first place?

I opened up the txt file which I am writing into.
The method displays characters correctly for Spanish, Italian, Hindi and Thai when I replace the http link and the encoding.

From my WinForm application I have a need to call javascript function from a WebBroswer control using something like this:
webBrowser1.Document.InvokeScript("show_line",...);
The show_line function is in javascript and looks like this:
function show_line(points)
{
for(var i=0;i<points.length;i++)
{
}
}
In other words, the parameter points is an array. My questions is how to pass an array of double from C# to javascript using
webBrowser1.Document.InvokeScript("show_line", points);
Thanks!

I'm trying to figure out how to set up the inside vertical & inside horizontal line to be setup as hairline weight.
That's what I have for now to setup the line for inside vertical and inside horizontal.
cellRange = oSheet.get_Range(oSheet.Cells[excelRow + 2, excelColumn + 3], oSheet.Cells[excelRow + 6, excelColumn + 7]);
cellRange.Borders[Excel.XlBordersIndex.xlInsideVertical].LineStyle = Excel.XlLineStyle.xlContinuous;
cellRange.Borders[Excel.XlBordersIndex.xlInsideHorizontal].LineStyle = Excel.XlLineStyle.xlContinuous;
Question is how do I set up the line weight to be hairline?

Try Excel.XlLineStyle.xlSlantDashDot;
For a list of supported styles, see here[^].
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

The line weight is kinda of too thick. I prefer hairline esp for printing.
|
|
|
|

now that I've got it!
I inserted a new statment line (see 2nd line)
cellRange = oSheet.get_Range(oSheet.Cells[excelRow + 2, excelColumn + 3], oSheet.Cells[excelRow + 6, excelColumn + 7]);
cellRange.Borders.Weight = Excel.XlBorderWeight.xlHairline;
cellRange.Borders[Excel.XlBordersIndex.xlInsideVertical].LineStyle = Excel.XlLineStyle.xlContinuous;
cellRange.Borders[Excel.XlBordersIndex.xlInsideHorizontal].LineStyle = Excel.XlLineStyle.xlContinuous;

Ok. Thanks for posting the solution.

through my application i want to open the *.cs file in vs2005 and set the cursor to the specified line.
in my application i search a specified text in the given cs file and show the filename and the line no,so i want to allow the user to goto the location of that file opened in vs2005.

There is already Find functionality in Visual Studio. I don't understand what you are trying to gain or accomplish outside of VS. In any case you would need to use automation and to my knowledge it is not available for execution outside of VS. It sounds like you need to create a Visual Studio Addin rather than an external application.

Interactively, in Visual Studio:
- use menu Edit/GoTo... (or CTRL/G) and type the line number
- when you have an error message in the output pane, double-click it
Programmatically, I don't think there is a way.
[ADDED]
i.e. I am unaware of an API that would support this. You could always try a little automation stuff. I'm not going to elaborate on it, IMO it isn't worth it; however Google knows all about it.

i found a way to open the cs file and navigate to the line i need , it can be done using switches in vs2005.
but there is a limitation , means when the ide is open when you open a file it won't navigate,it can only navigate to the line when the ide is starting up, so need to know if there is any one who knows a solution.
i don't want to open separate ide s for each file.
