In my application, I want to add a header and footer to a word document and download it. So I used to create HTML content and convert that content to a word document and download it. It is working on my local PC. When I hosted my application, images of the downloaded word document has not appeared.
I think images are saved in the server. when I download the document from the client-side machine, the images can't find the path. I used StreamWriter to convert HTML content to Word.
Please provide me a solution for how to bind an image with the absolute path with a permanent way to a word document through HTML or any other way to convert HTML content to word.
1st way I tried;
string renderHeaderImageLogo1 = Server.MapPath("~/Resources/ImageLogo/letter_header.jpg");
string renderFooterImageLogo1 = Server.MapPath("~/Resources/ImageLogo/letter_footer.jpg");
byte[] imageArrayHeader = System.IO.File.ReadAllBytes(renderHeaderImageLogo1);
byte[] imageArrayFooter = System.IO.File.ReadAllBytes(renderFooterImageLogo1);
string renderHeaderImageLogo = Convert.ToBase64String(imageArrayHeader);
string renderFooterImageLogo = Convert.ToBase64String(imageArrayFooter);
string headerImagePath = string.Empty;
string footerImagePath = string.Empty;
headerImagePath = "<div style=" + '"' + "text-align:" + headerImageAlignLocation + '"' + '"' + ">" + "<img src=" + "\"data:image/png;base64," + renderHeaderImageLogo + '"' + "/>" + "</div>";
footerImagePath = "<div style=" + '"' + "text-align:" + footerImageAlignLocation + '"' + '"' + ">" + "<img src=" + "\"data:image/png;base64," + renderFooterImageLogo + '"' + "/>" + "</div>";
2nd way i tried:
string renderHeaderImageLogo = Server.MapPath("~/Resources/ImageLogo/letter_header.jpg");
string renderFooterImageLogo = Server.MapPath("~/Resources/ImageLogo/letter_footer.jpg");
string headerImagePath = string.Empty;
string footerImagePath = string.Empty;
headerImagePath = "<div style=" + '"' + "text-align:" + headerImageAlignLocation + '"' + '"' + ">" + "<img src=" + '"' + renderHeaderImageLogo + '"' + "/>" + "</div>";
footerImagePath = "<div style=" + '"' + "text-align:" + footerImageAlignLocation + '"' + '"' + ">" + "<img src=" + '"' + renderFooterImageLogo + '"' + "/>" + "</div>";
3rd way I tried. This is not working for me. because I hosted my application as HTTPS
<img src="http://www.website.com/path/to/image.jpg" width="233" height="54" style="width:233pt;height:54pt;" />
This is the way I used to convert HTML content to word. content is the HTML content.
var npath = pathNew + (templateTitle.Replace(" ", "_")) + " (" + emp + "-" + empCallingName + ")" + ".doc";
try
{
using (StreamWriter writetext = new StreamWriter(npath))
{
writetext.WriteLine(content.ToString());
writetext.Close();
}
}
catch (Exception ex)
{
Log.Error(ex);
throw ex;
}

I am trying to get a snippet of HTML between to comments.
I will need to parse the HTML between the start/end later.
I am actually reading from an html file but for test purposes I mocked the following up:
string emailFeedTxtStart = "<!--FEED FOR RECEIPT GOES HERE-->";
string emailFeedTxtEnd = "<!--FEED FOR RECEIPT ENDS HERE-->";
string html =
emailFeedTxtStart + Environment.NewLine +
#"<td align=""center"">" + Environment.NewLine +
#"<table style=""table-layout:fixed;width:380px"" border=""0"" cellspacing=""0"" cellpadding=""0"">" + Environment.NewLine +
"<tbody>" + Environment.NewLine +
"<tr>" + Environment.NewLine +
"<td>" + Environment.NewLine +
"</td>" + Environment.NewLine +
"</tr>" + Environment.NewLine +
"</tbody>" + Environment.NewLine +
"</table>" + Environment.NewLine +
"</td>" + Environment.NewLine +
emailFeedTxtEnd;
string patternstart = Regex.Escape(emailFeedTxtStart);
string patternend = Regex.Escape(emailFeedTxtEnd);
string regexexpr = patternstart + #"(.*?)" + patternend;
//string regexexpr = #"(?<=" + patternstart + ")(.*?)(?=" + patternend + ")";
MatchCollection matches = Regex.Matches(#html, #regexexpr);
matches returned is 0.
(note there is a lot more HTML between the ).
Any help would be greatly appreciated.
What are you going to parse the HTML with after? Because there's probably a way you can just do away with actually manipulating the HTML string beforehand. Here's a solution anyway:
string afterFirst = html.Substring(Regex.Match(html, emailFeedTxtStart).Index + emailFeedTxtStart.Length);
string between = afterFirst.Substring(0, Regex.Match(afterFirst, emailFeedTxtEnd).Index);
private void ConvertHTMLtoDOCX(string txtcode)
{
System.Text.StringBuilder strBody = new System.Text.StringBuilder("");
strBody.Append("<html " + "xmlns:o='urn:schemas-microsoft-com:office:office' " + "xmlns:w='urn:schemas-microsoft-com:office:word'" + "xmlns='http://www.w3.org/TR/REC-html40'>" + "<head><title>Time</title>");
//The setting specifies document's view after it is downloaded as Print
//instead of the default Web Layout
strBody.Append("<!--[if gte mso 9]>" + "<xml>" + "<w:WordDocument>" + "<w:View>Print</w:View>" + "<w:DoNotOptimizeForBrowser/>" + "</w:WordDocument>" + "</xml>" + "<![endif]-->");
strBody.Append("<style>" + "<!-- /* Style Definitions */" + "#page Section1" + " {size:8.5in 11.0in; " + " margin:1.0in 1.25in 1.0in 1.25in ; " + " mso-header-margin:.5in; " + " mso-footer-margin:.5in; mso-paper-source:0;}" + " div.Section1" + " {page:Section1;}" + "-->" + "</style></head>");
strBody.Append("<body lang=EN-US style='tab-interval:.5in'>" + "<div class=Section1>" + Html_editor.Content + "</div></body></html>");
//Force this content to be downloaded
//as a Word document with the name of your choice
string FullFilePath = #"C:\Users\ravikant\Desktop\AR GitHub\07-05-2014\FinalTestARGithub\LetterTemplate\"+ txtcode+ ".docx";
FileInfo file = new FileInfo(FullFilePath);
if (file.Exists)
{
ClientScript.RegisterStartupScript(this.GetType(), "disExp", "<script>alert('File Already Exists');</script>");
}
else
{
Response.AppendHeader("Content-Type", "application/vnd.openxmlformats-officedocument.wordprocessingml.document");
Response.AppendHeader("Content-disposition", "inline; filename="+txtcode+".docx");
Response.Write(strBody);
}
}
Here is the code using the CONTENT-TYPE for .DOCX "application/vnd.openxmlformats-officedocument.wordprocessingml.document", the Content is corrupt while opening the file.
Try this to find out what is going on with the file.
I've done this with native word .docx, but not .docx generated in this manner, so it may or may not work.
Make a copy of the saved file, change its extention from .docx to .zip.
Try and open that. We are trying to find a file document.xml, which is normally in the "word" folder.
Open that in a text editor an see if anything is jumping out as wrong or try putting it through an XML validator. VisualStudio should be good enough to show any malformating.
Online XML Validator that might help: http://www.xmlvalidation.com/
The following lines are also suspect:
strBody.Append("<!--[if gte mso 9]>" + "<xml>" + "<w:WordDocument>" + "<w:View>Print</w:View>" + "<w:DoNotOptimizeForBrowser/>" + "</w:WordDocument>" + "</xml>" + "<![endif]-->");
As I'm unsure how word will handle IE conditional comments. Comment out or remove this line and see what happens.
strBody.Append("<style>" + "<!-- /* Style Definitions */" + "#page Section1" + " {size:8.5in 11.0in; " + " margin:1.0in 1.25in 1.0in 1.25in ; " + " mso-header-margin:.5in; " + " mso-footer-margin:.5in; mso-paper-source:0;}" + " div.Section1" + " {page:Section1;}" + "-->" + "</style></head>");
Due to the nested comments. <!-- /* */-->. Perhaps try changing it to: strBody.Append("</head>"); and see if that works.
I am trying to set the innerhtml of an html select tag but I cannot set this feature;therefor,I need to use the outerhtml feature.This way,not only is my code HARDCODE ,but also it is preposterous.I have already read 'InnerHTML IE 8 doesn't work properly? Resetting form',it did not help though.
I would really appreciate it if you tell me how to set the innerhtml feature of an html select tag.
My C# code:
public void SetDefaultValue(string ControlID, string ControlValue)
{
System.Windows.Forms.HtmlDocument doc = webBrowser1.Document;
HtmlElement HTMLControl = doc.GetElementById(ControlID);
string ListResult;
string ListInnerHTML = "";
ListInnerHTML += "<OPTION value = " + LstString + ">" + LstString + "</OPTION>";
ListResult = "<SELECT id = " + '"' + HTMLControl.Id + '"' + " type = " + '"' + HTMLControl.GetAttribute("type") + '"' + " title = " + '"' +
HTMLControl.GetAttribute("title") + '"' + " name = " + '"' + HTMLControl.Name + '"' + " value = " + '"' + HTMLControl.GetAttribute("value") +
'"' + " size = \"" + HTMLControl.GetAttribute("size") + '"' + HTMLControl.GetAttribute("multiple").ToString() + "\">" + ListInnerHTML + "</SELECT>";
HTMLControl.OuterHtml = ListResult;
}
or
string _lsthtml = _htmlel.OuterHtml;
string[] _parts = ControlValue.Split(new char[] { ',' });
string _lstinner = "";
foreach (string _lst in _parts)
_lstinner += "<option value=" + _lst + ">" + _lst + "</option>";
_lsthtml = _lsthtml.Insert(_lsthtml.IndexOf(">") + 1, _lstinner);
_htmlel.OuterHtml = _lsthtml;
This code works but I need something efficient and clean.
The ReturnControlType function returns the type of an html tag.
This is an official Internet Explorer bug:
BUG: Internet Explorer Fails to Set the innerHTML Property of the Select Object.
One workaround
You may try adding one of the following meta tags in your document's head:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
or
<meta http-equiv="X-UA-Compatible" content="IE=10" />
You should also properly format the option tag's value attribute (enclose LstString in '):
ListInnerHTML += "<OPTION value='" + LstString + "'>" + LstString + "</OPTION>";
A more reliable solution
As the fixes above might be a workaround for your code, I would suggest to use a more reliable approach. Consider adding a reference to Microsoft.mshtml to your project and modifying your method like this:
// add this to the top of the file containing your class
using mshtml;
public void SetDefaultValue(string ControlID, string ControlValue)
{
System.Windows.Forms.HtmlDocument doc = webBrowser1.Document;
IHTMLDocument2 document = doc.DomDocument as IHTMLDocument2;
var sel = doc.GetElementById(ControlID);
HTMLSelectElement domSelect = (HTMLSelectElement)sel.DomElement;
domSelect.options.length = 0;
HTMLOptionElement option;
// here you can dynamically add the options to the select element
for (int i = 0; i < 10; i++)
{
option = (HTMLOptionElement)document.createElement("option");
option.text = String.Format("text{0}", i);
option.value = String.Format("value{0}", i);
domSelect.options.add(option, 0);
}
}
I really don't know why innerHTML is not working for you.
If it just dosen't you could try an alternative:

demo
In this thread it is sugested you use the items collection of a control

I've been trying to find a regex pattern to replace all youtube URLs in a string with the iframe embed code (C#). Obviously the video ID has to extracted. Here is the url patterns that should match:
http://www.youtube.com/watch?v=bSiDLCf5u3s
https://www.youtube.com/watch?v=bSiDLCf5u3s
http://youtu.be/bSiDLCf5u3s
www.youtube.com/watch?v=bSiDLCf5u3s
youtu.be/bSiDLCf5u3s
http://www.youtube.com/watch?feature=player_embedded&v=bSiDLCf5u3s
www.youtube.com/watch?feature=player_embedded&v=bSiDLCf5u3s
all possible urls should be replaced with:
<iframe title='YouTube video player' width='480' height='390' src='http://www.youtube.com/embed/VIDEO_ID_EXTRACTED' frameborder='0' allowfullscreen='1'></iframe>
Can someone please point me to a right direction.
Thank you in advance
Here is the regex:
(?:https?:\/\/)?(?:www\.)?(?:(?:(?:youtube.com\/watch\?[^?]*v=|youtu.be\/)([\w\-]+))(?:[^\s?]+)?)
Should match all the links you posted and extracts the video ID as $1. And with the following code you replace the links with the <iframe/>:
const string input = "http://www.youtube.com/watch?v=bSiDLCf5u3s " +
"https://www.youtube.com/watch?v=bSiDLCf5u3s " +
"http://youtu.be/bSiDLCf5u3s " +
"www.youtube.com/watch?v=bSiDLCf5u3s " +
"youtu.be/bSiDLCf5u3s " +
"http://www.youtube.com/watch?feature=player_embedded&v=bSiDLCf5u3s " +
"www.youtube.com/watch?feature=player_embedded&v=bSiDLCf5u3s " +
"http://www.youtube.com/watch?v=_-QpUDvTdNY";
const string pattern = #"(?:https?:\/\/)?(?:www\.)?(?:(?:(?:youtube.com\/watch\?[^?]*v=|youtu.be\/)([\w\-]+))(?:[^\s?]+)?)";
const string replacement = "<iframe title='YouTube video player' width='480' height='390' src='http://www.youtube.com/embed/$1' frameborder='0' allowfullscreen='1'></iframe>";
var rgx = new Regex(pattern);
var result = rgx.Replace(input, replacement);
// result ==
// <iframe title='YouTube video player' width='480' height='390' src='https://www.youtube.com/embed/bSiDLCf5u3s' frameborder='0' allowfullscreen='1'></iframe>
// ...
//You can try this:
string strRegex = #"(?<EMBED>(<iframe|<object).*?src=[""'](?<SRC>(http:|https:)?//(www.)?[youtube\.com|youtu.be][^""']+).*?(</iframe>|</object>))";
Regex myRegex = new Regex(strRegex, RegexOptions.Singleline);
string strTargetString = #"<div align=""center""><iframe height=""315"" src=""//www.youtube.com/embed/NiCZAnmjYZ8"" frameborder=""0"" width=""560"" allowfullscreen=""true""></iframe></div> " + "\n" + #"<div align=""center""><iframe height=""315"" src=""//youtube.com/embed/NiCZAnmjYZ81"" frameborder=""0"" width=""570"" allowfullscreen=""""></iframe></div> " + "\n" + #"<div align=""center""><iframe height=""315"" src=""http://www.youtube.com/embed/NiCZAnmjYZ82"" frameborder=""0"" width=""560"" allowfullscreen=""""></iframe></div> " + "\n" + #"<div align=""center""><iframe height=""315"" src=""https://youtube.com/embed/NiCZAnmjYZ83"" frameborder=""0"" width=""560"" allowfullscreen=""""></iframe></div> " + "\n" + #"<div align=""center""><iframe height=""315"" src=""https://youtu.be/embed/NiCZAnmjYZ83"" frameborder=""0"" width=""560"" allowfullscreen=""""></iframe></div> " + "\n" + #"<div align=""center""><iframe height=""315"" src=""http://youtu.be/embed/NiCZAnmjYZ83"" frameborder=""0"" width=""560"" allowfullscreen=""""></iframe></div> " + "\n" + #"<a href=""https://youtu.be/embed/NiCZAnmjYZ83"">Youtube<a>" + "\n" + #"<div style=""text-align:center""><object width=""100%"" height=""100%"" id=""PlayerAS039128cb43804eb7894cba4e8b0220fc"" classid=""clsid:D27CDB6E-AE6D-11cf-96B8-444553540000""><param name=""movie"" value=""http://youtu.be/embed/NiCZAnmjYZ83""></param><param name=""allowFullScreen"" value=""true""></param><param name=""allowscriptaccess"" value=""always""></param><param value=""#000000"" name=""bgcolor""></param><param name=""wmode"" value=""opaque""></param><embed height=""100%"" width=""100%"" quality=""high"" bgcolor=""#000000"" flashvars="""" wmode=""opaque"" allowfullscreen=""true"" allowscriptaccess=""always"" name=""039128cb43804eb7894cba4e8b0220fc"" id=""039128cb43804eb7894cba4e8b0220fc"" style="""" src=""http://youtu.be/embed/NiCZAnmjYZ83"" type=""application/x-shockwave-flash""/></embed></object></div>" + "\n";

I'm trying to update a file via the GitHub API.
I've got everything setup, and in the end the actual file is updated, which is a good thing.
However, let's say I've got these 2 files in my repo
FileToBeUpdated.txt
README.md
And then I run my program
The FileToBeUpdated.txt is updated, like it should, however the README.md is deleted.
This is the code with the 5 steps to update the file:
private static void Main()
{
string shaForLatestCommit = GetSHAForLatestCommit();
string shaBaseTree = GetShaBaseTree(shaForLatestCommit);
string shaNewTree = CreateTree(shaBaseTree);
string shaNewCommit = CreateCommit(shaForLatestCommit, shaNewTree);
SetHeadPointer(shaNewCommit);
}
private static void SetHeadPointer(string shaNewCommit)
{
WebClient webClient = GetMeAFreshWebClient();
string contents = "{" +
"\"sha\":" + "\"" + shaNewCommit + "\", " +
// "\"force\":" + "\"true\"" +
"}";
// TODO validate ?
string downloadString = webClient.UploadString(Constants.Start + Constants.PathToRepo + "refs/heads/master", "PATCH", contents);
}
private static string CreateCommit(string latestCommit, string shaNewTree)
{
WebClient webClient = GetMeAFreshWebClient();
string contents = "{" +
"\"parents\" :[ \"" + latestCommit + "\" ], " +
"\"tree\":" + "\"" + shaNewTree + "\", " +
"\"message\":" + "\"test\", " +
"\"author\": { \"name\": \""+ Constants.Username +"\", \"email\": \""+ Constants.Email+"\",\"date\": \"" + DateTime.UtcNow.ToString("s", CultureInfo.InvariantCulture) + "\"}" +
"}";
string downloadString = webClient.UploadString(Constants.Start + Constants.PathToRepo + "commits", contents);
var foo = JsonConvert.DeserializeObject<CommitRootObject>(downloadString);
return foo.sha;
}
private static string CreateTree(string shaBaseTree)
{
WebClient webClient = GetMeAFreshWebClient();
string contents = "{" +
"\"tree\" :" +
"[ {" +
"\"base_tree\": " + "\"" + shaBaseTree + "\"" + "," +
"\"path\": " + "\"" + Constants.FileToChange + "\"" + " ," +
"\"content\":" + "\"" + DateTime.Now.ToLongTimeString() + "\"" +
"} ]" +
"}";
string downloadString = webClient.UploadString(Constants.Start + Constants.PathToRepo + "trees", contents);
var foo = JsonConvert.DeserializeObject<TreeRootObject>(downloadString);
return foo.sha;
}
private static string GetShaBaseTree(string latestCommit)
{
WebClient webClient = GetMeAFreshWebClient();
string downloadString = webClient.DownloadString(Constants.Start + Constants.PathToRepo + "commits/" + latestCommit);
var foo = JsonConvert.DeserializeObject<CommitRootObject>(downloadString);
return foo.tree.sha;
}
private static string GetSHAForLatestCommit()
{
WebClient webClient = GetMeAFreshWebClient();
string downloadString = webClient.DownloadString(Constants.Start + Constants.PathToRepo + "refs/heads/master");
var foo = JsonConvert.DeserializeObject<HeadRootObject>(downloadString);
return foo.#object.sha;
}
private static WebClient GetMeAFreshWebClient()
{
var webClient = new WebClient();
webClient.Headers.Add(string.Format("Authorization: token {0}", Constants.OAuthToken));
return webClient;
}
Which part am I missing? Am I using the wrong tree to start from?
It seems that in the function CreateTree I should set the base_tree at the root level, not at the level of each tree I create.
So in the function CreateTree the contents become this:
string contents = "{" +
"\"base_tree\": " + "\"" + shaBaseTree + "\"" + "," + // IT'S THIS LINE!
"\"tree\" :" +
"[ {" +
"\"path\": " + "\"" + Constants.FileToChange + "\"" + " ," +
"\"content\":" + "\"" + DateTime.Now.ToLongTimeString() + "\"" +
"} ]" +
"}";
