Mar 1, 2011
I am doing a project, In that i have to store some content in excel file and should have to save as sample.xls. If the file is already Exists, then have to store sample1.xls and again if it is exists, then sample2.xls...like that.... How in c# code.
Actually, I have developed an Website. In that, one page contains a message text field, If a user typed some text & clicked save button, that content should be store in excel file and save in different name with sequence series..
I have a full working web site that i ported to a new hosting company. In some pages i have links to PDF on the server (they do exist!) On the old server no problem. On the new one when user clicks on the link : error 404 file does not exist.. Should i look in the web.config ? i don't know where to start
ok i have a file link not in the vs 2010 project .basically i have a list page in which i want to show the files, one file each for different organization. how can i make a link to that xml file which exists outside the project
I have two websites. One site contains nothing but image files. This is a sub-domain of the main website. The main website allows the user to search a database of information and displays that information. I create a grid with a link to the file. In my row_databound function, I want to check to see if that file exists on my other website. If it doesn't I remove the link, otherwise I leaves a link to that file. how to verify that the LINK actually goes to a file that exists?
2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.
We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.
according below thread I change file name when users upload from file upload control:
[URL]
below is my code that I changed if(this.fuppdf.HasFile) { string path = Server.MapPath(".") + "../image/House/article/pdf";
[Code]....
if file name be duplicate it add 1 at the first of file name but here it doesn't work I mean when I upload file i.e catalog.pdf ("catalog is the text in txttitle) it saves in the host with this name catalog.pdf
but when again I want upload catalog.pdf in host it overwrite last (catalog.pdf) but I want if there was catalog.pdf file it saves with this name 1catalog.pdf in host
I want to create C# code that checks a hyperlink in a repeater and checks if the file exists. If not, the hyperlink is not visible. The path and document ar pulled from a sqldatasource:
I receive data in .csv format. I have a some records on a table, so what I need to do is to check if the data I receive exist on the table of records that I need to match against.
If the record exist, then an email/sms should be sent to notify me that the records has been matched and then that record should be flaged that it has been tested so that I don't test it again as the incoming data are saved.
When I update a js file in my asp.net project, I refresh the browser and the change shows up as expected. If I change a css file or an .aspx file, the change does not show in the browser. Not when I clear the browser's cache, not when I restart IIS (iisrestart). What could this possibly be?
How to check if a file exists on different domain?
If File.Exists("http://i1.asp.net/common/header/logo.png?cdn_id=01112010_2") Then Return String.Format("<img src={0} alt='' />", "http://i1.asp.net/common/header/logo.png?cdn_id=01112010_2" Else Return String.Empty 'always ends here [:(] End If
I have a ASP.Net website with links to files stored on a file server. These files are modified constantly and so the links will not always be valid, this includes changes to permissions, files being moved or deleted, etc. I implemented a method in the code-behind to check the validity of these links as they are constructed, if it fails the code will add CSS to change the color of link:
Check URL
/// <summary> /// Check if a URL exists. Method by http://www.vcskicks.com/check-website.php /// </summary> /// <param name="url">URL to validate</param> /// <returns>True if the URL was resolved, false otherwise</returns>
[Code]....
My problem is that not all the invalid links are getting the style added to them. The strange thing is that when I step through the method in debug mode using one of the bad links that was not colored, the method will return false and color the link as expected. There's a lot more involved then what I present above, but I searched the entire aspx code-behind for any other locations where the link url is being set and couldn't find any. I don't know if there's some post processing going on that somehow clears any styles that were applied to some of the links. The fact that some links are colored while others are not is very confusing to me. Has anyone else encountered similar behavior before?
I am taking backup for mdb file from source location to destination location.While using file.copy() function,how to check whether the folder is already exists or not.If exists means how to replace new one for existing one.Send C# code for replace new one for existing one.
I have a .net aspx project done with VS 2008 using the .Net 2.xxxx framework. This ASPX application is deployed on and 4 different 2003 Server boxes. 3 are running in total beautifully. In the 4th box is my issue. I do a FILE.EXISTS conditional test looking for case file pdf's. These case numbers are structured as such 2012-C-0421,001,0008.PDF
Please note the comma's used in the path. 3 of the 4 servers in court houses recognize the path to the pdf WITH the commas in them perfectly and the FILE.EXISTS works 100%. On the fourth box (same config we THINK) the exact same FILE.EXISTS does not return a hit even though we see the document sitting in the folder via explorer. IF we remove the commas and make it 2012-C-0421001008.pdf all is fine and document is indeed discovered with the EXISTS.
WHY on this one server does the original ducument path not function. We can not ask the court houses to change the way they store their documents so I need to make this work like the other 3. Again... same version..same .net framework... same OS (2003 server)
In my c# class I wrote I have a photo property that returns the photo source if the image exists (nothing or default image otherwise). In my code I use:
public string Photo { get { string source = "~/images/recipes/" + id + ".jpg"; if (File.Exists(source)) return "~/images/recipes/" + id + ".jpg";.......
If I get the FileInfo() information for this image I see that I tries to find this image in the following directory: C:Program Files (x86)Common FilesMicrosoft SharedDevServer10.0~images ecipes Of course the image is not located in that directory and File.Exists is returning me the wrong value.how can I fix this?
I have a large web application that uses File.Exists() in a global file utility class flawlessy for several years now. I just built a new ASMX web service that calls that same method in our file utility class, and it returns False for the same exact file paths that are being passed in the web application. The paths are absolute system file paths, and they match on both the web service and the web app.I am confused... Why might this happen? The method I am talking about is only a few lines of code. A couple of lines simply validate the file id parameter being sent into the method. The last remaining line is this:
[Code]....
The previous line of code calls another method that uses a String.Format to insert the file id into the file path. That's it.
