Web Forms :: Append Incrementing Index Number To Uploaded Filenames?
Oct 30, 2010
Essentially, if the file already exists, I want to append an index number to the end of the filename, incrementing upwards from 1. The following almost works, but adds numbers on as it increments upwards:
I'm serving up PDFs from a SQL db and presenting them in the browser. I'm trying to figure out a way to embed a number in the PDF dynamically so that the recordID for that PDFs SQL record is available to me when the user submits the XML form data. The user hits the submit button on the form and the form submits its XML data to my submission page. If there is some way of changing the submission URL on the fly then I could do a query string to pass my self the recordID. I'm not generating the PDF in code, its being created by hand and then uploaded to my site.EditUser is given a link someServer.com/pdfLink.aspx?formID=5 they go there and that pages pulls a PDF from the DB and displays it. This pulls up acrobat in browser full size so my aspx page isn't in control of submitting the completed form, Acrobat is. The user fills out the form and hits the submit button in the form. This submit button was set up at form design time to point to another page someSite.com/pdfSubmit.aspx The submit button posts the XML data to that page and I can process it. I need the recordID in the query string for the someSite.com/pdfSubmit.aspx page. To do this I would need to modify the PDF to either add the recordID and query string to the submit button's submit URL, or embed it in the PDF else ware. The big question is how do I modify the PDF just before I display it via someServer.com/pdfLink.aspx?formID=5 to do either of these two options.
On my products page I have a small thumbnail and a description that is pulled from the database, since there is space restraints, how do I allow a max amount of characters, and if the description is longer append ... to the end? I'm using a data repeater and data binding for the content inside it.
I have a dropdown binded with database value Eg : A001, A002, A003 etc. When ever i use to select the first value A001 , it is not going for postback. After selecting the second index value A002 n then selecting the first value A001 , i use to post back. And i dnt want to use appent data bound here.

I am trying access the row index on this GridView, but the e.CommandArgument gives me a value of an empty string "" , so the the error handler kicks in. What do you think I am missing.
I have a table that contains about 8000 records and I need to be able to select any given sequence of 250 subsequent rows by a specific row index of teh table...
how I can go about that easily using a dataview without building a secondary table and just pushing the records I need into it?
I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.
Usually I just lurk around and try to figure things out, but I'm stuck on this one.
Here's what I'm trying to do:
I'm using jcarousel to display thumbnails for an image gallery. When you click an image to display the large one below, I want the carousel to jump to that image instead of resetting back to the beginning. This is can be done in jcarousel by setting a "start" parameter. What I need is something that tells jcarousel what the current image is (what was just clicked).
Here's what I was thinking:
The thumbnail code is generated using a list. I thought if I could get the index number of each list item to a variable, that would get me what I needed for jcarousel.
The above code exports gridview1 data to excel, but the requirement is export data with row no as first column in Excel. I tried to add row number in dataset that binding to gridview, when we sort data in gridview, row number are not in correct order.
Here upon loading the page there will be 4 panels having their own timer controls (having interval 1000) for incrementing a variable "a". But the problem is that, as I have used static variable that's why all the timer's are sharing the variable "a" and creating a problem like each panel's label showing a value incremented by 4 after every second. Can any body solve this problem..
I'm having some evils trying to get my GridView control to behave. I have the below code, which successfully displays all the files in the directory. However I require two changes, both of which I am struggling with:
a) Currently the URL you get when clicking on the URL field is [URL] (ie my home directory with the filename). What I require is that the 'Display Text' be the filename only, and the URL be my desired text followed by the filename eg: [URL]
b) I want only to see the files that start with a certain prefix eg "Pay". I can do that with something like: string[] filelist = Directory.GetFiles((@"C:MFData","Pay*.*"); but this doesn't like to bind to my Gridview!
const string DocumentFolderPhysicalPath = (@"C:MFData"); const string DocumentFolderUrl = (@"C:MFData"); [URL]; ; // now it is hardcoded but you could retreive it automatically HyperLinkField hyperLinkField = new HyperLinkField(); hyperLinkField.DataTextField = "Name"; hyperLinkField.DataNavigateUrlFields = new string[] { "Name" }; //Would like this to work! //HyperLinkField hyperLinkField2 = new HyperLinkField(); //hyperLinkField2.DataTextField = "Destination"; //hyperLinkField2.DataNavigateUrlFields = new string[] { (@"C:MFData") + "Name" }; GridView1.DataSource = GetDocuments(DocumentFolderPhysicalPath); GridView1.Columns.Add(hyperLinkField); GridView1.DataBind();
private System.IO.FileInfo[] GetDocuments(string physicalPath) { System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(physicalPath); if (directory.Exists) { return directory.GetFiles(); } else { throw new System.IO.DirectoryNotFoundException(physicalPath); } }
I'm trying to read all filenames from a specified (server- not client) folder, and insert all the filenames into a javascript Array. It should behave like the Directory.GetFiles method in ASP.NET C#. I created a new array, and I just need the loop method (Javascript or jQuery) to iterate in the specific folder, and insert all the filenames into the array.
I'm trying to optimize my ASP.NET thumbnailing script, so it doesn't resize all the images all the time, and one part of the problem is choosing the hash function for the thumbnail naming/checking procedure.Is crc32 up to the task - I'm asking cause the input data is small(only relative path, size and date)?
remember my previous post about how to use 4 timers controls for incrementing 4 individual variables. I have fixed it below is the code for doing that. But there is again a problem,I want to increment the variable "hh" by 10 at button "btnbid"'s click event (remember it'll(hh) increment by 1 at each timers tick event but when a button is pressed it'll increment by 10). When I'm trying to this it's not incrementing can any body tell me why this is happening is there any way to fix it.
I've got a piece of code that is driving me crazy. No matter what I try, I can't get the javascript var to increment. BTW, I am using the jquery library. <script type="text/javascript"> function formValidate() { var counter = 0; $.get("/Validation/ValidateNameFields", { inputString: $('#FirstName').val(), controlName: 'FirstName', messagePrefix: 'First Name' }, function(data) { if (data != "") { eval(data);counter++; } }); alert(counter) } </script>
The eval(data); works just like its suppose to (it sets text to a label). The counter is always zero.
in my aspx page user is creating a request and when the request is created a request_id is generated automatically in databse..i want to retreive tht particular request_id and display it on the same web page.
here is my code-
protected void Button1_Click(object sender, EventArgs e) { String selection = DropDownList1.Text.ToString(); String status = "inactive"; try { ConnectionStringSettings set = ConfigurationManager.ConnectionStrings["WATERMARKING"]; String cns = set.ConnectionString; SqlConnection cnn = new SqlConnection(cns); cnn.Open(); String query = "Insert into REQUESTS (USERNAME,REQUEST_TYPE,STATUS) values ('" + uName + "','" + selection + "','" + status + "')"; SqlCommand cmd = new SqlCommand(query, cnn); cmd.ExecuteNonQuery(); //Response.Write("Request created Successfully "); //MessageBox.Show("request created successfully"); Label4.Visible.Equals(true); Label4.Text="request created successfully"; Label5.Text = "Your Request ID is"; Label6.Text = "ID required to Check the Request Status"; } catch (Exception err) { //Response.Write("error generated while raising request"+err); Label4.Visible.Equals(true); Label4.Text = "request creation error"+err; } }
here wen a value is getting inserted in REQUESTS table a column named REQUEST_ID gets populated and i want to display that value on the web page
any stored proceudre in which incrementing of integers, floating point nums alphabets and alpha numeric value incrmenting take place based on the datatype entered.
