An error has occurred opening extern DTD (w3.org, xhtml1-transitional.dtd). 503 Server Unavailable

- by Cheeso

I'm trying to do xpath queries over an xhtml document. The document looks like this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> .... </head> <body> ... </body> </html> Because the document includes various char entities (  and so on), I need to use the DTD, in order to load it with an XmlReader. So my code looks like this: var reader = XmlReader.Create(sr, new XmlReaderSettings { ProhibitDtd = false }); But when I run this, it returns An error has occurred while opening external DTD 'http://www.w3.org/TR/xhtml1-transitional.dtd': The remote server returned an error: (503) Server Unavailable. Now, I know why I am getting the 503 error. W3C explained it very clearly. But I still want to validate the document. How can I validate with the DTD, and get the entity definitions, without hitting the w3.org website? related: - java.io.IOException: Server returned HTTP response code: 503

LaTeX indentation (formatting) in Emacs

- by nkuyu

Hi, what is the correct way to do indentation of a LaTeX document in Emacs (AucTex)? For example when I have a list: \begin{itemize} \item orem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam enim urna, mattis eu aliquet eget, condimentum id nibh. In hac habitasse platea dictumst. \item orem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam enim urna, mattis eu aliquet eget, condimentum id nibh. In hac habitasse platea dictumst. \end{document} and would like to ended up with: \begin{itemize} \item orem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam enim urna, mattis eu aliquet eget, condimentum id nibh. In hac habitasse platea dictumst. \item orem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam enim urna, mattis eu aliquet eget, condimentum id nibh. In hac habitasse platea dictumst. \end{document} I tried indent-region but it doesn't do anything and the LaTeX-fill-* produces weird results like: \item orem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam enim urna, mattis eu aliquet eget, condimentum id nibh. In hac habitasse platea dictumst. \item orem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam enim urna, mattis eu aliquet eget, condimentum id nibh. In hac habitasse platea dictumst. \end{document} Thanks!

Not able to use 7-Zip to compress stdin and output with stdout?

I get the error "Not implemented". I want to compress a file using 7-Zip via stdin then take the data via stdout and do more conversions with my application. In the man page it shows this example: % echo foo | 7z a dummy -tgzip -si -so /dev/null I am using Windows and C#.

How to replace openSSL calls with C# code?

- by fonix232

Hey there again! Today I ran into a problem when I was making a new theme creator for chrome. As you may know, Chrome uses a "new" file format, called CRX, to manage it's plugins and themes. It is a basic zip file, but a bit modified: "Cr24" + derkey + signature + zipFile And here comes the problem. There are only two CRX creators, written in Ruby or Python. I don't know neither language too much (had some basic experience in Python though, but mostly with PyS60), so I would like to ask you to help me convert this python app to a C# code that doesn't depend on external programs. Also, here is the source of crxmake.py: #!/usr/bin/python # Cribbed from http://github.com/Constellation/crxmake/blob/master/lib/crxmake.rb # and http://src.chromium.org/viewvc/chrome/trunk/src/chrome/tools/extensions/chromium_extension.py?revision=14872&content-type=text/plain&pathrev=14872 # from: http://grack.com/blog/2009/11/09/packing-chrome-extensions-in-python/ import sys from array import * from subprocess import * import os import tempfile def main(argv): arg0,dir,key,output = argv # zip up the directory input = dir + ".zip" if not os.path.exists(input): os.system("cd %(dir)s; zip -r ../%(input)s . -x '.svn/*'" % locals()) else: print "'%s' already exists using it" % input # Sign the zip file with the private key in PEM format signature = Popen(["openssl", "sha1", "-sign", key, input], stdout=PIPE).stdout.read(); # Convert the PEM key to DER (and extract the public form) for inclusion in the CRX header derkey = Popen(["openssl", "rsa", "-pubout", "-inform", "PEM", "-outform", "DER", "-in", key], stdout=PIPE).stdout.read(); out=open(output, "wb"); out.write("Cr24") # Extension file magic number header = array("l"); header.append(2); # Version 2 header.append(len(derkey)); header.append(len(signature)); header.tofile(out); out.write(derkey) out.write(signature) out.write(open(input).read()) os.unlink(input) print "Done." if __name__ == '__main__': main(sys.argv) Please could you help me?

iText PDFReader Extremely Slow To Open

- by Wbmstrmjb

I have some code that combines a few pages of acro forms (with acrofields in tact) and then at the end writes some JS to the entire document. It is the PdfReader in the function adding the JS that is taking extremely long to instantiate (about 12 seconds for a 1MB file). Here is the code (pretty simple): public static byte[] AddJavascript(byte[] document, string js) { PdfReader reader = new PdfReader(new RandomAccessFileOrArray(document), null); MemoryStream msOutput = new MemoryStream(); PdfStamper stamper = new PdfStamper(reader, msOutput); PdfWriter writer = stamper.Writer; writer.AddJavaScript(js); stamper.Close(); reader.Close(); byte[] withJS = msOutput.GetBuffer(); return withJS; } I have benchmarked the above and the line that is slow is the first one. I have tried reading it from a file instead of memory and tried using a MemoryStream instead of the RandomAccessFileOrArray. Nothing makes it any faster. If I add JS to a single page document, it is very fast. So my thought is that the code that combines the pages is somehow making the PDF slow to read for the PdfReader. Here is the combine code: public static byte[] CombineFiles(List<byte[]> sourceFiles) { MemoryStream output = new MemoryStream(); PdfCopyFields copier = new PdfCopyFields(output); try { output.Position = 0; foreach (var fileBytes in sourceFiles) { PdfReader fileReader = new PdfReader(fileBytes); copier.AddDocument(fileReader); } } catch (Exception exception) { //throw } finally { copier.Close(); } byte[] concat = output.GetBuffer(); return concat; } I am using PdfCopyFields because I need to preserve the form fields and so cannot use the PdfCopy or PdfSmartCopy. This combine code is very fast (few ms) and produces working documents. The AddJS code above is called after it and the PdfReader open is the slow piece. Any ideas?

jquery newbie: combine validate with hidding submit button.

- by Jeffb

I'm new a jQuery. I have gotten validate to work with my form (MVC 1.0 / C#) with this: <script type="text/javascript"> if (document.forms.length > 0) { document.forms[0].id = "PageForm"; document.forms[0].name = "PageForm"; } $(document).ready(function() { $("#PageForm").validate({ rules: { SigP: { required: true } }, messages: { SigP: "<font color='red'><b>A Sig Value is required. </b></font>" } }); }); </script> I also want to hide the Submit button to prevent twitchy mouse syndrome from causing duplicate entry before the controller completes and redirects (I'm using an GPR pattern). The following works for this purpose: <script type="text/javascript"> // // prevent double-click on submit // jQuery('input[type=submit]').click(function() { if (jQuery.data(this, 'clicked')) { return false; } else { jQuery.data(this, 'clicked', true); return true; } }); </script> However, I can't get the two to work together. Specifically, if validate fails after the Submit button is clicked (which happens given how the form works), then I can't get the form submitted again unless I do a browser refresh that resets the 'clicked' property. How can I rewrite the second method above to not set the clicked property unless the form validates? Thx.

Extracting images from a PDF

- by sagar

My Query I want to extract only images from a PDF document, using Objective-C in an iPhone Application. My Efforts I have gone through the info on this link, which has details regarding different operators on PDF documents. I also studied this document from Apple about PDF parsing with Quartz. I also went through the entire PDF reference document from the Adobe site. According to that document, for each image there are the following operators: q Q BI EI I have created a table to get the image: myTable = CGPDFOperatorTableCreate(); CGPDFOperatorTableSetCallback(myTable, "q", arrayCallback2); CGPDFOperatorTableSetCallback(myTable, "TJ", arrayCallback); CGPDFOperatorTableSetCallback(myTable, "Tj", stringCallback); I use this method to get the image: void arrayCallback2(CGPDFScannerRef inScanner, void *userInfo) { // THIS DOESN'T WORK // CGPDFStreamRef stream; // represents a sequence of bytes // if (CGPDFDictionaryGetStream (d, "BI", &stream)){ // CGPDFDataFormat t=CGPDFDataFormatJPEG2000; // CFDataRef data = CGPDFStreamCopyData (stream, &t); // } } This method is called for the operator "q", but I don't know how to extract an image from it. What should be the solution for extracting the images from the PDF documents? Thanks in advance for your kind help.

Setting System.Drawing.Color through .NET COM Interop

- by Maxim

I am trying to use Aspose.Words library through COM Interop. There is one critical problem: I cannot set color. It is supposed to work by assigning to DocumentBuilder.Font.Color, but when I try to do it I get OLE error 0x80131509. My problem is pretty much like this one: http://bit.ly/cuvWfc update: Code Sample: from win32com.client import Dispatch Doc = Dispatch("Aspose.Words.Document") Builder = Dispatch("Aspose.Words.DocumentBuilder") Builder.Document = Doc print Builder.Font.Size print Builder.Font.Color Result: 12.0 Traceback (most recent call last): File "aaa.py", line 6, in <module> print Builder.Font.Color File "D:\Python26\lib\site-packages\win32com\client\dynamic.py", line 501, in __getattr__ ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1) pywintypes.com_error: (-2146233079, 'OLE error 0x80131509', None, None) Using something like Font.Color = 0xff0000 fails with same error message While this code works ok: using Aspose.Words; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Document doc = new Document(); DocumentBuilder builder = new DocumentBuilder(doc); builder.Font.Color = System.Drawing.Color.Blue; builder.Write("aaa"); doc.Save("c:\\1.doc"); } } } So it looks like COM Interop problem.

Why do properties require explicit typing during compilation?

- by ctpenrose

Compilation using property syntax requires the type of the receiver to be known at compile time. I may not understand something, but this seems like a broken or incomplete compiler implementation considering that Objective-C is a dynamic language. The property "comment" is defined with: @property (nonatomic, retain) NSString *comment; and synthesized with: @synthesize comment; "document" is an instance of one of several classes which conform to: @protocol DocumentComment <NSObject> @property (nonatomic, retain) NSString *comment; @end and is simply declared as: id document; When using the following property syntax: stringObject = document.comment; the following error is generated by gcc: error: request for member 'comment' in something not a structure or union However, the following equivalent receiver-method syntax, compiles without warning or error and works fine, as expected, at run-time: stringObject = [document comment]; I don't understand why properties require the type of the receiver to be known at compile time. Is there something I am missing? I simply use the latter syntax to avoid the error in situations where the receiving object has a dynamic type. Properties seem half-baked.

Texture2D problem

- by Anders Karlsson

I have a problem that is driving me crazy, I want to write a number of texts on the screen using Texture2D however I only seem to be able to write the first one. If I individually write one of the labels it works but not if I write all of them, only the first label is displayed. Let me show some code: -(void)drawText:(NSString*)theString AtX:(float)X Y:(float)Y withFont:(UIFont*)aFont { // set color glColor4f(1, 0, 0, 1.0); // Enable modes needed for drawing glEnableClientState(GL_TEXTURE_COORD_ARRAY); Texture2D* textTexture = [[Texture2D alloc] initWithString:theString dimensions:viewSize // 320x480 alignment:UITextAlignmentLeft font:aFont]; glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); [textTexture drawInRect:CGRectMake(X,Y,1,1)]; glDisableClientState(GL_TEXTURE_COORD_ARRAY); [textTexture release]; } When I call this drawText once it seems to display the text properly, but if I call it a second time nothing seems to be displayed. Somebody has an idea what it could be? The states like GL_BLEND and GL_TEXTURE_2D have been enabled in the view setup function. In the Texture2D the dimensions are 512x512 as I pass the whole screen to function. If I don't pass that the text gets enlarged and fuzzy. I am a bit uncertain about that parameter. TIA for any help.

ASP Classic, SQL 2008, XML Output, and DSN vs DSN-Less Produces Chinese Letters

- by RoLYroLLs

I've been having a problem for the past month and can't seem to figure out what is wrong. Here's the setup and a little background. Background: I have a web-host who was running my website on Windows Server 2003 and SQL Server 2000. One of my webpages returned a result set from a stored procedure from the SQL server as xml. Below is the code: Stored Procedure: select top 10 1 as tag , null as parent , column1 as [item!1!column1!element] , column2 as [item!1!column2!element] from table1 for XML EXPLICIT ASP Page: index.asp Call OpenConn Set cmd = Server.CreateObject("ADODB.Command") With cmd .ActiveConnection = dbc .CommandText = "name of proc" .CommandType = adCmdStoredProc .Parameters.Append .CreateParameter("@RetVal", adInteger, adParamReturnValue, 4) .Parameters.Append .CreateParameter("@Level", adInteger, adParamInput, 4, Level) End With Set rsItems = Server.CreateObject("ADODB.Recordset") With rsItems .CursorLocation = adUseClient .CursorType = adOpenStatic .LockType = adLockBatchOptimistic Set .Source = cmd .Open Set .ActiveConnection = Nothing End With If NOT rsItems.BOF AND NOT rsItems.EOF Then OutputXMLQueryResults rsItems,"items" End If Set rsItems = Nothing Set cmd = Nothing Call CloseConn Sub OpenConn() strConn = "Provider=SQLOLEDB;Data Source=[hidden];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" Set dbc = Server.CreateObject("ADODB.Connection") dbc.open strConn End Sub Sub CloseConn() If IsObject(dbc) Then If dbc.State = adStateOpen Then dbc.Close End If Set dbc = Nothing End If End Sub Sub OutputXMLQueryResults(RS,RootElementName) Response.Clear Response.ContentType = "text/xml" Response.Codepage = 65001 Response.Charset = "utf-8" Response.Write "" Response.Write "" While Not RS.EOF Response.Write RS(0).Value RS.MoveNext WEnd Response.Write "" Response.End End Sub Present: All was working great, until my host upgraded to Windows Server 2008 and SQL Server 2008. All of the sudden I was getting results like this: From Browser: From View Source: However, I found that if I use a DSN connection strConn = "DSN=[my DSN Name];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" it works perfectly fine! My current host is not going to support DSN any longer, but that's out of scope for this issue. Someone told me to use an ADO.Stream object instead of a Recordset object, but I'm unsure how to implement that. Question: Has anyone run into this and found a way to fix it? What about that ADO.Stream object, can someone help me with a sample that would fit my code?

Unit tests for deep cloning

- by Will Dean

Let's say I have a complex .NET class, with lots of arrays and other class object members. I need to be able to generate a deep clone of this object - so I write a Clone() method, and implement it with a simple BinaryFormatter serialize/deserialize - or perhaps I do the deep clone using some other technique which is more error prone and I'd like to make sure is tested. OK, so now (ok, I should have done it first) I'd like write tests which cover the cloning. All the members of the class are private, and my architecture is so good (!) that I haven't needed to write hundreds of public properties or other accessors. The class isn't IComparable or IEquatable, because that's not needed by the application. My unit tests are in a separate assembly to the production code. What approaches do people take to testing that the cloned object is a good copy? Do you write (or rewrite once you discover the need for the clone) all your unit tests for the class so that they can be invoked with either a 'virgin' object or with a clone of it? How would you test if part of the cloning wasn't deep enough - as this is just the kind of problem which can give hideous-to-find bugs later?

FancyBox Callback Keydown

- by headShrinker

I have been working on this code, and I can't seem to figure it out. Fancybox's callbacks don't seem to work at all. I have the keyboard bound to the pagination for this gallery. But I want to unbind the keyboard from the table when fancybox opens. When fancybox opens nothing changes.... What to do?? $(document).ready(function() { $('a.active').click(function() { var url = $(this).attr('href'); $('#ajaxTable').load(url+'/1'); return false; }); $("a.fancy").fancybox({ callbackOnStart: function() { $('a#gleft a#gright').unbind("keydown"); }, 'frameWidth': 570, 'frameHeight': 470 }) $(document).keydown(function(event) { if(event.keyCode == 37 ) { var url = $('a#gleft').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } else if(event.keyCode == 39 ) { var url = $('a#gright').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } }); });

Append a dynamically changing watermark to a PDF in SharePoint

- by ccomet

This is primarily a question of possibilities more than instructions. I'm a programming consultant working on a WSS project site system for my client. We have a document library in which files are uploaded to go through a complex approval process. With multiple stages in this process, we have an extra field which dictates what the current status of the document is. Now, my client has become enamored with the idea of PDF watermarking. He wants the document (which is already a PDF) to be affixed with a watermark corresponding to the current status, such that with each stage of the approval process the watermark will change. One method, the traditional method for PDF watermarking, of accomplishing this is to have one "clean" copy of the document somewhere hidden on the site, and create a new PDF from it that has the watermark at each stage of the approval process. Since the filename will never change, this new PDF can be uploaded continually to a public library, always overwriting the old version and simulating a "dynamically changing watermark". However, in the various stages there will also be people uploading clean copies with corrections and suggestions, nevermind the complex nature of juggling around two libraries and the fact we double the number of files stored. My client and I agree that this is not a practical path to choose. What we would like to do is be able to "modify" the watermark in a PDF, so that we only have to keep one copy of the file. Unfortunately, from what I've seen, in most cases when you make something like a watermark, which in its nature is supposed to be "unmodifyable", you won't be able to edit it later. So, is it possible to have a part of a PDF which cannot be changed by anyone who downloads the file, but can be changed as part of a workflow or other object model process? Thanks in advance!

jquery: prepopulating autocomplete fields

- by David Tildon

I'm using the tokenizing autocomplete plugin for jquery ( http://loopj.com/2009/04/25/jquery-plugin-tokenizing-autocomplete-text-entry ). I mostly use Ruby, and I'm really unfamiliar with javascript, though. My basic setup looks like this, and works fine for a new, blank form: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search" }); }); The problem comes when I try to prepopulate it, like for an edit page. I'm trying to do something like this (where the "#tag_ids_field" text box contains the JSON when the page is loaded - that way is just cleaner on the application side of things). $(document).ready(function () { var tags = $("#tag_ids_field").html(); $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: tags }); }); However, when the page loads I see that it's just filled with hundreds of entries that read 'undefined'. I get this even if I take the JSON output that Rails provides and try sticking it right in the .js file: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: "[{\"id\":\"44\",\"name\":\"omnis sit impedit et numquam voluptas enim\"},{\"id\":\"515\",\"name\":\"deserunt odit id doloremque reiciendis aliquid qui vel\"},{\"id\":\"943\",\"name\":\"exercitationem numquam possimus quasi iste nisi illum\"}]" }); }); That's obviously not a solution, I just tried it out of frustration and I get the same behavior. My two questions: One, why are my text boxes being filled with "undefined" tags when I try to prepopulate, and how can I get them to prepopulate successfully? Two, I'm planning on having many autocomplete fields like this on the same page (for when several records are edited at once - they all query the same place). How can I make each autocomplete field take it's prepopulated values from it's own textbox? Something like (applying these settings to all input boxes with a certain class, not just the one of a particular id): $(document).ready(function () { $(".tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: (the contents of that particular ".tag_ids_field" input box) }); });

count on LINQ union

- by brechtvhb

I'm having this link statement: List<UserGroup> domains = UserRepository.Instance.UserIsAdminOf(currentUser.User_ID); query = (from doc in _db.Repository<Document>() join uug in _db.Repository<User_UserGroup>() on doc.DocumentFrom equals uug.User_ID where domains.Contains(uug.UserGroup) select doc) .Union(from doc in _db.Repository<Document>() join uug in _db.Repository<User_UserGroup>() on doc.DocumentTo equals uug.User_ID where domains.Contains(uug.UserGroup) select doc); Running this statement doesn't cause any problems. But when I want to count the resultset the query suddenly runs quite slow. totalRecords = query.Count(); The result of this query is : SELECT COUNT([t5].[DocumentID]) FROM ( SELECT [t4].[DocumentID], [t4].[DocumentFrom], [t4].[DocumentTo] FROM ( SELECT [t0].[DocumentID], [t0].[DocumentFrom], [t0].[DocumentTo FROM [dbo].[Document] AS [t0] INNER JOIN [dbo].[User_UserGroup] AS [t1] ON [t0].[DocumentFrom] = [t1].[User_ID] WHERE ([t1].[UserGroupID] = 2) OR ([t1].[UserGroupID] = 3) OR ([t1].[UserGroupID] = 6) UNION SELECT [t2].[DocumentID], [t2].[DocumentFrom], [t2].[DocumentTo] FROM [dbo].[Document] AS [t2] INNER JOIN [dbo].[User_UserGroup] AS [t3] ON [t2].[DocumentTo] = [t3].[User_ID] WHERE ([t3].[UserGroupID] = 2) OR ([t3].[UserGroupID] = 3) OR ([t3].[UserGroupID] = 6) ) AS [t4] ) AS [t5] Can anyone help me to improve the speed of the count query?

Firefox drags div like it was an image, javascript event handlers possibly to blame

- by user281434

Hi, I'm using this HTML,CSS and Javascript code (in one document together if you want to test it out): <style type="text/css"> #slider_container { width: 200px; height: 30px; background-color: red; display:block; } #slider { width: 20px; height: 30px; background-color: blue; display:block; position:absolute; left:0; } </style> <script type="text/javascript" src="../../js/libs/jquery-1.4.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#slider").mousedown(function() { $(document).mousemove(function(evnt) { $("#test").html("sliding"); }).mouseup(function() { $("#test").html("not sliding"); $(document).unbind("mousemove mouseup"); });}); }); </script> <div id="test">a</div> <div id="slider_container"> <div id="slider"></div> </div> Everything (surprisingly) works fine in IE, but firefox seems to totally clusterf*ck when this javascript is used. The first "slide" is okay, you drag, it says "sliding", you drop, it says "not sliding". On the second "slide" (or mousedown if you will), firefox suddenly thinks the div is an image or link and wants to drag it around. Screenshot of the dragging: http://i.imgur.com/nPJxZ.jpg Obviously the blue div half-positioned in the red div is the one being dragged. Windows does not capture the cursor when you take a screenshot, but it's a stop sign. Is there someway to prevent this default behaviour?

Right Click Context Menu Script for iFrame

- by Ramiz Uddin

The context of the problem is related to an application which is based on single-page Ajax application which consists of three different panels (iframes). The layout of the page is as follows: _________________________________________________ | | | Frame A | FRAME C |__________________| | | | Frame B | | | | | | | | | | | | | | | The problem is with the context menu (right-click menu) in Frame C. The position of the context menu is not perfectly positioned with the mouse click. Particularly, if you drag and increase the size of the Frame C window. Code snippet: var rightedge = parent.frames["FrameC"].frameElement.clientWidth-event.clientX; var bottomedge = parent.frames["FrameC"].frameElement.clientHeight-event.clientY; if (rightedge < document.getElementById('Menu').offsetWidth) menuCoorX = parent.frames["FrameC"].frameElement.scrollLeft + event.clientX - document.getElementById('Menu').offsetWidth; else menuCoorX = parent.frames["FrameC"].frameElement.scrollLeft + event.clientX; if (bottomedge < document.getElementById('Menu').offsetHeight) menuCoorY = parent.frames["FrameC"].frameElement.scrollTop + event.clientY - document.getElementById('Menu').offsetHeight; else menuCoorY = parent.frames["FrameC"].frameElement.scrollTop + event.clientY; Currently, we need it to work only for IE (7 and 8). Please, help! Thanks.

Replace image in word doc using OpenXML

- by fearofawhackplanet

Following on from my last question here OpenXML looks like it probably does exactly what I want, but the documentation is terrible. An hour of googling hasn't got me any closer to figuring out what I need to do. I have a word document. I want to add an image to that word document (using word) in such a way that I can then open the document in OpenXML and replace that image. Should be simple enough, yes? I'm assuming I should be able to give my image 'placeholder' an id of some sort and then use GetPartById to locate the image and replace it. Would this be the correct method? What is this Id? How do you add it using Word? Every example I can find which does anything remotely similar starts by building the whole word document from scratch in ML, which really isn't a lot of use. EDIT: it occured to me that it would be easier to just replace the image in the media folder with the new image, but again can't find any indication of how to do this.

I'm submitting the form created by Formtastic inside a modal box using ajax: <% semantic_form_remote_for @contact_form, :url => '/request/contact' do |f| %> I have a validation plugin verifying the fields on the form: $(document).ready(function() { $("#new_contact_form").ketchup(); }); The problem is that semantic_form_remote_for generates an onSubmit ajax request that the jQuery validation plugins won't prevent, since it's not a normal form submission. One question on stackoverflow suggests using :condition on the remote form declaration to fire a javascript function, but I can't do that since I'm not using a function, but rather relying on a jQuery handler. I also tried putting ketchup within a submit event handler: $(document).ready(function() { $("#new_contact_form").submit(function() { $('#new_contact_form').ketchup(); }); }); No luck. Form still submits. I also tried using the beforeSend option of jQuery.ajax: $(document).ready(function() { jQuery.ajax( { beforeSend: function(){ $('#new_contact_form').ketchup(); } }); }); Validation fires off, but form is still submitted. I switched to jQuery Validation plugin just to see if it was due to some limitation in Ketchup. It turns out that Validation has a submitHandler option: $(document).ready(function() { $('#new_contact_form').validate({ submitHandler: function(form) { jQuery.ajax({ data:jQuery.param(jQuery('#new_contact_form').serializeArray()), dataType:'script', type:'post', url:'/request/contact' }); return false; } }); }); This works when I use a regular semantic_form_for instead of semantic_form_remote_for, but alas, I would rather use Ketchup. Is Ketchup just woefully lacking? Am I forced to use jQuery Validation?

Accessing an iFrame's dom from a Firefox Extension

- by luisgo

Hi all, I've spent a long time trying different things to get this to work but nothing does and documentation is not helping much. I'm trying to populate a form inside an iframe that I dynamically inject into a page. To inject that iframe I do: myObject.iframe = document.createElement("iframe"); myObject.iframe.setAttribute("src", data.url); myObject.iframe.setAttribute("id","extension-iframe"); myObject.window.document.getElementById('publisher').appendChild(myObject.iframe); myObject.iframe.addEventListener("load", function(){ myObject.populate(data); }, false); which works fine and DOES trigger the populate() method. My problem is getting the document or window objects for that iframe. I've tried all of the following: myObject.iframe.window myObject.iframe.document myObject.iframe.content but these are all undefined. I also tried passing the event object to that iframe's load event listener and then doing: event.originalTarget But that didn't work either. I am reading the following documentation: https://developer.mozilla.org/En/Working%5Fwith%5Fwindows%5Fin%5Fchrome%5Fcode https://developer.mozilla.org/en/Code%5Fsnippets/Interaction%5Fbetween%5Fprivileged%5Fand%5Fnon-privileged%5Fpages But either I'm not understanding it or it's just not properly explained. Can anyone shed some light? Thanks!

(solved) jQuery click and drag/scroll window: jagged movement

- by Josh

Edit: derp, using pageX/Y instead of clientX/Y -- apparently scrollBy expects input with that offset rather than the other. Jaggy movement gone. I am getting jagged movement when doing small scroll increments using the following bindings. Can anyone point me in the right direction for how to smooth this out? FYI, its intermittent. It seems like, if I click and hold for a second, then drag at a decent speed there are no problems. Edit: What the hell? I get this output on debug... obvious jog backwards and forwards. This will happen in succession and seems to have no correlation with the mouse, other than the mouse is moving. x 398 : 403 y 374 : 377 x 403 : 399 y 377 : 374 x 399 : 404 y 374 : 377 Josh sococo.client.panMap = function(e){ e.preventDefault(); var movex = sococo.client.currX - e.pageX ; var movey = sococo.client.currY - e.pageY; console.log( sococo.client.currX +" : " + e.pageX ); window.scrollBy(movex,movey); sococo.client.currY = e.pageY; sococo.client.currX = e.pageX; } $(document).mousedown( function(e){ e.preventDefault(); sococo.client.currX = e.pageX; sococo.client.currY = e.pageY; $(document).bind( "mousemove", sococo.client.panMap ); }); $(document).mouseup( function(e){ e.preventDefault(); $(document).unbind( "mousemove", sococo.client.panMap ); });

UpdatePanel Javascript Error on Adding Clientside Listbox items After postback

- by DBMaster

Hi, I have a Dynamic list control of Metabuilder.Webcontrol inside UpdatePanel,I am adding removing Items using Javascript from the list control. It works fine Inside UpdatePanel. I have another control Gridview along with checkbox's which require postback to get populated. Once It gets populated successfully inside update without postback. I checked few rows and wanted to add them into List Control using Javascript. It says "object doesn't support this property or method" function addItmList(idv,valItem) { var list =document.getElementById('ctl00_ContentPlaceHolder1_MyList'); //var generatedName = "newItem" + ( list.options.length + 1 ); list.Add(idv,valItem); } function checkitemvalues() { var gvET = document.getElementById("ctl00_ContentPlaceHolder1_grd"); var target = document.getElementById('ctl00_ContentPlaceHolder1_lstIControl'); var newOption = window.document.createElement('OPTION'); var rCount = gvET.rows.length; var rowIdx = 0; var tcount = 1; for (rowIdx; rowIdx<=rCount-1; rowIdx++) { var rowElement = gvET.rows[rowIdx]; var chkBox = rowElement.cells[0].firstChild; var cod = rowElement.cells[1].innerText; var desc = rowElement.cells[2].innerText; if (chkBox.checked == true){ addItmList(rowElement.cells[1].innerText,rowElement.cells[2].innerText); } } } Code Behind ScriptManager.RegisterClientScriptBlock( Me.Page, Me.GetType(), MyList.ClientID, "" & vbCr & vbLf & "window.mylistid='" + MyList.ClientID + "';" & vbCr & vbLf & "", True ) Remember my code works fine. It cannot maintain the state of List Control thats why It says Object reqiured. Can any one help me out. After Update Panel Why My javascript doesnt add Items into ListBox. Thanks In advance
