I'm working on a project that I'm trying to export data from textboxes in asp.net website project to a powerpoint file. I writing ofcourse in C#.The whole concept is to use the data the a user inserts to the text boxes and they are sent after clicking a OK button directly to a powerpoint file. I'm using OFFICE 2007 so I'm using powerpoint 2007 for this.A similar concept that I'm already using in the website project is doing the same thing but exporting to a WORD format file. I bumped against this following site a software to perform this and it's called: SoftArtisans. There website is http://www.softartisans.com/ .
Now, if somebody has a clue or a tutorial how I can do this, Export to a powerpoint file I'll be very thankful. I am also using Microsoft SQL Server 2008 R2 to save the data in the database, so if maybe someone knows how to export the data from the textboxes from the website TO the database and then TO the powerpoint file

I have designed a report in RDLC. I am using Visual Studio 2008 and C#. Below is my code to export the report in excel. It always export the report to xls format which is Excel 2003. Excel 2003 has limited rows upto 65000. When i get rows more than 65000 for example 90000 then the export fails. Excel 2007 has power to handle more than 1000000 rows. I want to export the RDLC report to Excel 2007 to overcome the issue. how by modifying the following code i can export the report to Excel 2007.
byte[] bytes = null; bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings); Response.Buffer = true; Response.Clear(); Response.ContentType = mimeType; Response.AddHeader("content-disposition", "attachment; filename=Rendered Services." + extension); Response.BinaryWrite(bytes); Response.Flush();
I have a web application (ASP.NET 3.5) that allows the users to upload their own excel sheet. This sheet contains information about items that needs to be inserted to SQL Server 2005.
I already have this functionality, however, it's very slow (it takes almost 20 minutes to finish the request). I need a better way to handle this problem.
The sheet contains information about an item. These properties will be inserted into multiple tables for example (Books, Authors, Titles ... etc ...).
What I'm currently doing is the following:
The user uploads the file. The application opens the file. Read each row and update the database accordingly.
When i export the data table to excel 2003 i get the output in a very fast manner and when i want to use the same in excel 2007 debugging gets stopped and nothing happens.... It does not show any errror on it to. When i slowly debugged i find that in saveas() it takes longer time and it seems like execution gets stopped in this process.
Its like in new window it shows loading for more than 10 min and after some time the particular window gets closed and nothing happens can anyone tell me what can be wrong.When the same code works great when i export to 2003.
The code Export data from GridView to Excel is working fine but in our office network all machines have MS Office2007 so when user click to export data and save the file it is always saving in the old format and when user wants to open that excel file then a popup asks the compatibility of version to open yes or no. So to open the file user everytime click Yes.
I just want to export data from GridView to Excel in MS Office 2007 version, so that when user click to open then it directly open the file without asking any question.
Following is the code which I used in my projects's web pages:
Therefore I cannot try any other code. I just want minor ammendment's in this code to accomplish this task.
I'm working on a web app and need to stream various files. I can do pdfs, images, and older Office documents. However, when I try to do with 2007 documents, it breaks. Here is my code:
Response.Buffer = true; Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); switch (FileExtension.ToLower()) { case "pdf": Response.ContentType = "application/pdf"; break; case "doc": Response.ContentType = "application/msword"; break; case "docx": Response.ContentType = "application/vnd.ms-word.document.12"; break; case "xls": Response.ContentType = "application/vnd.ms-excel"; break; case "xlsx": Response.ContentType = "application/vnd.ms-excel.12"; break; default: Response.ContentType = "image/jpeg"; break; } Response.BinaryWrite(buffer);
The error that I get is:
An invalid character was found in text content. Error processing resource 'http://DomainName/GetFile.aspx.
We have an ASP.net site where we need to generate PowerPoint slides of the data. The slides will need to include charts and tables. I have come across Aspose.Slides online which seems a good option. What are your experiences with Aspose.Slides? Are there any other options we can pursue?
I need idea of new implementation. I have a client application which will interact with my application. My application needs to count how many slides are available in the powerpoint presentation file and it needs to provide it to the end user. And also user can ask this application to provide only first two slides or 3 and 4th slides to retrieve from the PPT file. How do I approach this. If any one has answer and source code please provide it.
Im am generating a ppt-file using this tutorial here Step 4 describes how to swap out the image placeholder.
Is there any way to resize the placeholder so it can keep the dimensions?
Edit:
users can upload images of them selves. The images are stored on the server. I am generating a ppt-file with one user per slide. And for every slide there will be an image, if any. I can of course get the dimensions of every image, but how do I replace the placeholder with an image of another dimension than the placeholder?
I'm generating a PowerPoint file using this as reference. A user can search other users based on many criterias. Information based on the user is saved in the PowerPoint file. But I can't save all PowerPoint files on the server.So, the user needs to right click a link, choose "Save As...", and save the file locally.
Nothing should be saved on the server. I have been Googling, but I'm not sure what to look for.I seems I am a bad googler. I removed "powerpoint" from my search string, and there are a lot of hits.
is there any way to open a powerpoint file and read the text in it to a string. i've imported the msoft.officeinterop namespace but i only get options for word. any help is greatly appreciated. i'm using vb.net
As you can see I overwrite the placeholder with "Test User", and it works like a charm.I need to add an image (as a placeholder) to this pptx-file. When I do that (and run the code again) I get a corrupted pptx-file?
Error message: PowerPoint removed unreadable content in output.pptx. You should review this presentation to determine whether any content was unexpectedly changed or removed.
Edit: If I try the original code (which is slightly modified since I dont have Adventureworks), I get some other kind of error message:
This file may have become corrupt or damaged for the following reasons: Third-party XML editors sometimes create files that are not compatible with Microsoft Office XML specifications.
The file has been purposely corrupted with the intent to harm your computer or your data. Be cautious when opening a file from an unknown source.
PowerPoint can attempt to recover data from the file, but some presentation data, such as shapes, text,and formatting, may be lost.
Do one of the following:If you want to recover data from the file, click Yes.If you do not want to recoverdata from the file, click No.
I want to include some pie charts present in my power point file. Can any one tell me how to do that? or atleast help in creating pie charts on my web page.
