Code behind file changing

Posted By:      Posted Date: September 26, 2010    Points: 0   Category :ASP.Net

I have a code behind file which has only a few placeholders and literal. The gridview control and others are added in real time according to program conditions. I noticed that once in a while th eprogram stopped working because the .aspx file is changed  and some of the place holders disappeared - Why? (the bolded lines disappeared once in a while)

How do I run php code with an html file by changing the web.config file?


I have a windows server and would like to add php code to my .html files. I know this is possible with linux servers with .htaccess files but how do I do it with a windows server? I called my hosting provider and they said I need to forget about .htaccess and look into the web.config file. What I want is for my server to read html files and execute any php code it finds. I can't find the code I need to add to the web.config file.

I am quite new to all this.  I switched my server to a windows server with IIS 7 a few months ago. But I find asp.net way too difficult for this beginner. I can't switch back to a linux server since my business partner is creating pages with ASP.net

I just want to execute php code inside of html files.  Any help is greatly appreciated, thank you.

Code Name WinFS: Revolutionary File Storage System Lets Users Search and Manage Files Based on Conte


One of the monumental problems organizations face today is aggregating information that's stored in disparate formats. Knowledge workers have long wanted to be able to search for content independent of format. The next version of the Windows operating system, code-named "Longhorn," boasts a new storage subsystem that makes that task easier. That subsystem, code-named "WinFS," allows the user to perform searches based on the metadata of the stored item, regardless of what type of file it is or which application created it. This article covers the basic architecture of WinFS and explains how to use the WinFS managed API.

How to change this code to allow more file uploads

I have a page currently setup to upload 1 image at a time, it uploaded the image, then creates a thumbnail for that image in the same directory. Client needs / wants to be able to upload a few more images at the same time. So i would like to see if i can use the existing code that works, but setup to upload a few more images and process them all to create the thumbnails. I currently have a page that allows them to upload 5 images at a time and that works fine, but its just simple uploading the images, nothing else is happening at that moment. Here is the code i am working with: protected void UploadBtn_Click(Object sender, EventArgs e) { String pth = Server.MapPath("~/gallery/homebirth/images/"); String UploadedFile = MyFile.PostedFile.FileName; int ExtractPos = UploadedFile.LastIndexOf("/") + 1; //to retrieve only Filename from the complete path String UploadedFileName = UploadedFile.Substring(ExtractPos, UploadedFile.Length - ExtractPos); // Display information about posted file. Div is invisible by default FileName.InnerHtml = UploadedFileName; MyContentType.InnerHtml = MyFile.PostedFile.ContentType; ContentLength.InnerHtml = MyFile.PostedFile.ContentLength.ToString(); //div is made visible FileDetails.Visible = true; // Save up

Sharing a file handler between managed and unmanaged code?

This is related to Interops, and sharing a file handler between a WPF UI and a native C++ DLL. I'm working on an application using MVVM as a guide. I want to use WPF for the UI, however it is a complex scientific application, which requires performance, and I am using C++ along with some GPU based code for all the modeling/processing. This is a Windows based app, no real network comm involved. I come across a challenge in terms of storing data. The data is multi-dimensional, and can be projected in many ways, while each projection can be processed/filtered in many ways too. I end up with a tree of data, with the raw data at the root and many branches. XML seems like an ideal way to store the information about this dataset, but as far as the raw data, it is not so convenient. I read about base64 encoding and the various binary-XML techniques, but see a major issue: the size of the converted data (150% of the raw) which in my case is huge (raw data is easily 200MBs+, and the multitude of projections can make it several 100's of MBs easily). There is the option of saving several files, but then it may become a nightmare for a user to 'transfer' files properly, so a one-file system seems best. I basically need to have the XML-like structure accessible to the UI, while the raw data needs to be accessed by the unmanaged code. So I was thinking I could concat

Custom SharePoint Timer Job doesn't run after changing code and restart timer services.

Hi We are facing an issue that our custom SharePonit Timer Job doesn't run after a changing the code. First, we developed and deployed a timer job. It worked fine for a few days, then we detected a memory leak and killed the OWSTIMER.EXE. (Maybe we should uninstall the timer job and restart the timer services nicely). We fixed the problem, redeployed the fix as a feature (assemblies are re-GACed ...) to our small SharePoint farm (one web server, one services server), restarted the SharePonit Timer Services. Now we can see the time job in Timer Job Definition in Central Admin but the job never runs (Since it doesn't run, the timer job status page doesn't have any info about it). We tried the same process in a dev environment with SharePoint signle box installation. The timer job just works fine. I did some search on Internet and followed some instruction to clear the cache from "C:\ProgramData\Microsoft\SharePoint\Config\1d50d73c-9bf1-4444-85a9-910ed050d1bf" by 1. Remove all the xml2. Clear the cache.ini with "1".3. restart the timer services. It still doesn't fix the problem.Please advise what else I can do. I even rename the timer job and redeploy it. It doesn't help. I checked the even log and SharePoing log and couldn't see anything wrong. Our OS is W2K8.         public override void FeatureActivated(SPFeatureReceiverProperties properties)        {

In my sitemap the title of the page is everytime same. but I want tpo change it at runtime. I am using multiple sitemaps and My sitemap is not the default one. its name is rootSitemap.
