I'm trying to find any code working in the ASP.NET project that would be able to read, change the font, save the DOC file. Does anyone know any code to modify a DOC file format ?
You need a 3rd party control for that, like Aspose.Words. Without a control you would need to use server-side Office automation which is highly not recommended.

I am working for an office-add-in for PowerPoint. I need to assign some unique identifier to my files, so that files can be identified in any dot net application. I did similar work for Word using custom properties. But for PowerPoint there is no way to read/ write custom property using office.js.
The only way I found using tags:
https://learn.microsoft.com/en-us/office/dev/add-ins/powerpoint/tagging-presentations-slides-shapes
but when I add tags to the presentation, I am not able to see those tags in presentation directly, I am able to read/ write through code only. Also I am not getting a way to read these tags from dot net application.
Any help will be great.
I am storing my files to azure blob. And reading files in my dot net core application to identify whether it has been saved from an office-add in or not. I am using syncfusion library in dot net core application to work with files.
Try this:
Open a PPT file and add a few tags "wwwww", "yyyyy", "zzzzz".
Close and save the file.
Add ".zip" onto the end of the filename.
Use any unzipper program to unzip the file.
Search the folder of unzipped files for "wwwww", "yyyyy", "zzzzz".
This should tell you where/how tags are stored in the OOXML.
Your .NET app should be able to use the OOXML SDK to read the tags of a PPT file.
At present, Syncfusion Presentation library do not have support to read and edit the tags of PowerPoint elements. Please track the status of this feature from below link,
https://www.syncfusion.com/feedback/1800/create-and-edit-tags-for-powerpoint-elements
However, kindly try the below suggested workaround solutions to achieve your requirement,
Using Shape.Name property:
Add a shape with unique name while generating a document from Office-Addin. You can use Shape.Name property for this.
In .NET Core application, identify the corresponding shape by using Shape.ShapeName property of Syncfusion Presentation library and decide whether its generated by Office-Addin or not. You can refer below UG documentation for more details,
https://help.syncfusion.com/file-formats/presentation/working-with-shapes#specifying-shape-properties
Using custom meta-data on Presentation:
PowerPoint Javascript API documentation states that, when we apply the tags for Presentation object it’s maintained as a custom property of PowerPoint document.
Screenshot
If so, you can able to iterate the custom property of PowerPoint document using Presentation.CustomDocumentProperties API of Syncfusion Presentation library. You can refer below UG documentation for more details,

I am making a GUI in which based on user login a certain number of buttons are supposed to be enabled and the rest disabled. I have to do this with the help of a config file.
Can anyone please share any examples or references if they know.
Thank you :)
You can write a Qt application that parses an xml file by validating it against a predefined xsd file.
The xml file had layout, grid, button text, and other various information for the user.
The goal of this was the end user could create his/her own xml file to custom configure their buttons.
What you need:
Define a data structure that will match your objective
Validate and test XML
Create a widget with whatever kind of layout you want. If you're doing buttons, you probably want to use a QGrid
Load the XML and configure your layout.
Is there any way to apply CSS styles to an SSRS rdl file ?
Note: it's not necessary to BIDS, my main goal is to edit the rdl file regardless of the used tool.
Thanks
From what I read, an RDL file is written in XML so yes, you can use XSLT to turn it into HTML, to which you can apply CSS.
Well sort of. You can do what Mario suggested but you can't really do that to the RDL as is. You need to CALL IT from a service to HTML and then apply a CSS to that. The RDL File contains definitions but not the report data. So if you changed it for markup you would still have to connect to a database and read the RDL language. As far as I know RDL is a propertiary SSRS langauge that needs a converter to tell it how to display. This is generally the service at http:// (servername)/ReportServer which has the information built in that can translate it. You could not alter this file directly without A LOT of work to transform it as it would then need to know a connection string, how the data was presented.
To do what you want I would think you could do this:
Deploy a report
Call a form to be populated in HTML like:
<form id="ssrsform" action="http://(servername)/ReportServer/Pages/ReportViewer.aspx(Path)&rs:Command=Render" method="post" target="_self" >
.....(options and settings)....
</form>
Apply a CSS form to the HTML file directly that is calling the webserivce.
IMHO changing a proprietary language file like RDL before it transmits to HTML would be hard as you need to account for the data you get as well as just the connection string.
I'm really stuck. I'm working on an integration project where I'm creating a html fragment using ASP.NET. This fragment will be included as part of another site. The html fragment is created using a simple ASP.NET page with a minimal code behind file.
Te site that will include this html fragment is running PHP. The developer there is complaining that my code is sending the byte order mark as part of the html fragment and this is making his life difficult.
I'm using Visual Studio 2010 for development. I've saved the relevant aspx and aspx.cs files as UTF-8 without signature. However, this doesn't seem to have made a difference and now I'm pretty much out of ideas. The rest of the site is set to use UTF-8 as standard (defined in web.config).
Where should I be looking to alter the BOM behaviour for my aspx file?
If you save the file in Visual Studio I believe it will keep adding the BOM. You need to use a different editor to remove the marker such as NotePad++.
Actually in the advanced save as dialog in Visual Studio there is also an option to save UTF-8 without signature. Have you tried this?
It's confirmed in this question.
You can also use plain old NotePad to save with a different encoding.
Save As...Encoding DropDown.
Can someone point me to some code/tutorial on how to upload pdf files and store them, then moreover how to use a pdf reader to display the file as read only in an asp.net application.
Is there a PDF reader already in the visual studio toolbox?
The approach I would use in this situation is to upload the PDF as you would any other file, then use a tool like GhostScript to convert the PDF pages into image files that you can show in ASP .Net.
Here's a tutorial doing that in C# http://www.codeproject.com/KB/cs/GhostScriptUseWithCSharp.aspx
Adobe provides (on acrobat.com) a free service which provides you with the ability to upload pdf (and also other types like doc...) and then embed a nice flash interface for displaying the files on your page.
It's pretty helpful as you can store some 5 gigs of files here.
But if you want to let the users upload their own files then this won't help you.
PDF is a final format file, ie its is read-only for the most part and can be embedded into the page via the <object> tag, except if you mean downloadable by the user.
Displaying PDF is generally done by rasterising to an image format for display (ie as an image on the page or via a richer interface (with zooming etc) through flash/silverlight etc.
You can use [GhostScript][1] to interpret PDF files and convert them to an image.
[1]: http://www.GhostScript .com
Uploading a PDF is just like any other file. Use the ASP.NET file uploader control:
http://www.codeproject.com/KB/aspnet/fileupload.aspx
In order to view the PDF in an ASP.NET application, you could either depend on Acrobat being there or use a PDF Viewer control.
The company I work for, Atalasoft, sells a PDF Reader add-on to our web viewer controls. You can learn more here: http://www.atalasoft.com/products/dotimage/pdf-reader
