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.
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 am using the code below which I have found on one of the forums to download a file in remote server. it seems it is working. However, the downloaded file is corrupted and I cannot unzip.
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
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.
In my asp.net application. I am making one pdf template then bind the data with that template then save it on one folder. then pop the pdf file from that saved directory. Now all are fine. The problem is when i host the application sometimes i am getting message as the file is damaged or corrupted with message box. But when i get this error the i am going to refresh the page i will get the pdf file with data. Why It is not coming very first time. Why it is getting when we click on the refresh of browser.
i have an image and an imagebutton, they are inside a listview and get their imageurl from databinding, i would like to know, if maybe the databinding value is empty, instead of showing a big red x, is there anyway to maybe make it link to a default image when the value is empty instead?
I'm having a problem with a web app I'm managing. Users starting receiving the following error occasionally:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
The problem is that it's not a cluster - it's a single Windows 2003 server. After digging around, it appears that adding a machineKey section and some extra attributes to the Pages directive in my web.config resolves this error:
After changing these two things in my web.config, the error goes away, but now I have a new problem - Instead of an error that my viewstate is invalid, the app just "Forgets" who my user is, and sends them back to the login page. Now, the users are browsing through the application, and then they're unexpectedly sent to the login page, even after they've already been logged in for a few minutes. While I can't force this to happen, it usually happens within visiting 10-12 different pages, so pretty frequently.
I'd love a resolution to this - does anybody know what else might be causing the viewstate error on a single server, or what I can do to ensure that it's validated properly?
I have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?
I have a situation where my session variables seem to get corrupted. I Page_Load I am calling 2 subs. Each of them fills a GridView with data from a table. I am saving the content of each Data.DataTable into Session Variables:
After I call the 1st sub and I debug the session variable "mySqlDataTable1" contains all the data from the table. After I call the 2nd sub and I debug the session variable "mySqlDataTable1" has been changed and contains a mix of data from the 2 tables.
I have written the following code to download a file from sharepoint. The downloded file works fine in only some machines. For others, it says that the file is corrupted. The issue is for MS Office and image files, however the PDF is not having any issues. We have identified the issue of corruption as due to the addition of a hexadecimal number at the top of the file contents. When it is removed, the file gets opened correctly. The hexadecimal character has been traced out to be representing the file size in bytes. Why this is happening only in some machines and how can we fix it?
Is there a way I could dynamically add a Image1 to the while loop in the below code (contained within the div) By this I mean actually adding an asp image to the div? via the code. At the moment as I see it the code looks for an asp image but Ive seen no way you can "add" it to my dynamic content:
using (OdbcCommand cmd = new OdbcCommand("SELECT Wallpostings FROM WallPosting WHERE UserID=" + userId + " ORDER BY idWallPosting DESC", cn)) { using (OdbcDataReader reader = cmd.ExecuteReader()) { var divHtml = new System.Text.StringBuilder(); while (reader.Read())...........
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm"); request.Method = WebRequestMethods.Ftp.UploadFile; // This example assumes the FTP site uses anonymous logon. request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com"); // Copy the contents of the file to the request stream. StreamReader sourceStream = new StreamReader("testfile.txt"); byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); sourceStream.Close(); request.ContentLength = fileContents.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(fileContents, 0, fileContents.Length); requestStream.Close(); FtpWebResponse response = (FtpWebResponse)request.GetResponse();
For uploading images and songs to the server. But the file is getting corrupted on upload. Normal upload is getting error due to security reason and access issues.
Had to dwell on to ftp. But in this case, file is getting corrupted.
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
