I'm using a log file to document info while getting and processing info from a form
1. if not post back, open the log file, build page, send form. 2. get submit back from form, possible post back if errors, possible writes to log file, if no errors definitely writes to log file, and send confirm page. 3. postback from confirm page can either be going back to form or finalizing, and send acknowledge page, then done.
so I need to keep the logfile object between direct postbacks to the form, or posting back to orignal form page after gettting a postback from a confirm page.
this type of file setup works fine, it creates a single log file per day:
[Code]....
then successive writes are like this:
[Code]....
when the form submit comes back from the original send/submit, lf from above is 'nothing'
saw the post about 9 ways to maintain state, not sure at all which would be most appropriate to keep the lf object accessible between possible postbacks and submits to the form.
I have function called getdoctor () in asmx file I wannna call this webmethod from javascript and get the result into flat text i.e i wanna get the name doctor name not in neither in xml or json
When I hit the enter key, when the input box has focus - the form submits. If I add another input box it doesn't submit. How can I avoid the auto submit when there's only one input box?
I have a form with a number of validators. When I click my Submit button the validators fire and I can see my error messages, however the Form still submits and calls my onclick event. Does anyone know what's causing that? The form shouldn't submit with errors.
it's a simple question and yet i couldn't figure how this works.I created an aspx page without any master page.Put one text box on the form.then use Internet Explorer 8 and visit that page.typed something and hit ENTER on the keyboard. The form submits (judging by that page being refreshed). I didn't even put any buttons on the form. Just the textbox. What triggers the postback?I further added one < asp:Button > next to the textbox and wired the button to see if it's been clicked.
i repeat the same thing, typed something in the textbox and hit ENTER on the keyboard. The form submitted but the button wasn't click. What's happening? How the postback is triggered if it's not from the button? This is happening in Mozila Firefox too except that when i added a button on the page, the button will be hit when ENTER on the keyboard is pressed.Can anyone shed some light as to why the button i added didn't respond to the ENTER on the keyboard in IE8?
I am using the SQL Membership provider to handle authentication. On one particular page the main function is the registration of an asset. You have to log in first. No problem. I also have required field validators on this registration form that work nicely. The problem is, if you log in, go to that page, then click the 'logout' button, it seems to submit the form (bypassing all my validation in the process)! I know I can't be the first person to come across this, so I'm guessing I've set something up wrong somewhere.
My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
I am trying to implement an ajax form inside of a jquery ui dialog.
I have a view with a button that opens the modal dialog form, makes an ajax call to an action that loads a partial view into the dialog. The partial view consists of a form created via Ajax.begin form. When I post the form I close the modal and update a div on my main page. This all works fine.
The problem is, the next time I open the modal and submit the form the http POST for the form is called twice. The third time I open/submit the form is submitted 3 times and so on...
It seems as if the submit button/form is bound multiple times and I cant figure out how to fix this.
Here is my code...
first the jquery call to load the ajax form partial view and create the modal...
i have flat files in some direcotry. each flat file contains around 60,000 rows of data. earlier we were using excel sheets to upload data. but now the challenge is it is taking more time to upload data into DB tables. which is the best way to upload such a huge data into db tables. can we use SSIS for uploading data. if so, how can we achieve that.
retrieving data from sql server 2000 database which has four tables. 3 of them has 256 datafields. And I need to retrieve all columns from all table for last 3years. All tables are related through a coman primary key.
I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.
VB.NET Code: Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged    For Each li As ListItem In lbLogs.Items      If li.Selected Then        Using sw As New StreamReader(li.Value)          txtLog.Text = sw.ReadToEnd           sw.Close()        End Using      End If    Next  End Sub
I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.
I have a flat file with text that has a special character like this: "RIBA® Generic Strip Labeling." so the registerd symbol is coming as square when i am simply reading the file in c#. is there a way to read the symbol as is and print on screen? i am working in on a console application. Also other german characters, not all but a few are showing as squares as well.
I am working on an SSIS package that needs to read a flat file and load the data into a SQL table. The problem is, the flat file name changes because it incorporates a date similar to this:
fileName_2010-04-12.txt
I found this site that shows how to set up a dynamic flat file connection:
[URL]
I understand the principle, but what I'm struggling with is using it in my data flow task. I need to configure the column mappings. In the PROPERTIES of the flat file connection, under expressions, I set up a ConnectionString with the following:
@[User::DataLoadDir] + @[User::priceFileName]
where [User::DataLoadDir] is the path where the file resides and [User::priceFileName] is a variable that should have the name of the specific file I want to read.
However, when I try to set the column mappings in the flat file connection, it's pulling the column headings for a different file in the same directory.
I have to get input from user in flat file format.then convert it to xml. Then, i have to store the entries into a datatable in the database. say 1,2,3 a,b,c be the user entries. it shall be stored into a table with 2 columns.how to do this?
i have an aspx page that loads and displays a text file in a broswer window and it used to work, I made no changes to it and now testing shows additional content appended below the file.
Here is the text file:
testing...
Here is what is displayed:
[Code]....
The additional output looks like the aspx page itself, which has only a close button incase the file load fails.
This is what I have right now for a file residing on the same server and it works.
Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter objStreamWriter = File.CreateText(FILENAME) dr = myCommand.ExecuteReader() While dr.Read() objStreamWriter.WriteLine("{0}|{1}|{2:yyyy-MM-dd}|{3:yyyy-MM-dd}", dr(0), dr(1), dr(2), dr(3)) End While objStreamWriter.Close()
I was planning on FTPing the file to another server once done but is there a way to do it on a remote server? i.e create a text file on a remote server and write to it? Did not find any instances of that usage. How to use ServerXMLHTTP to replace Server.MapPath in this instance?
i have a fileupload control which i use to upload file to the server. after the upload is successful i enable a hyperlink with the name of the uploaded file.
i want the user to be able to view this file in the browser after the file has been uploaded.
i did try assigning the navigateurl for the hyperlink = HttpContext.Current.Request.MapPath(".") + "\folder1\" + fileName;
which dint work. all uploaded files are being stored in a folder inside my solution directory on the server.
Is there a pre-existing library to extract plain text form Open XML file formats (e.g. docx, pptx, and xlsx) files?
I require this to populate a lucene.net index.
I've found this example which extracts text from docx and it seems to work okay. But before building my own solution based on this I was wondering if there's something already available for the other file formats?
I am trying to export images from my SQL server to SSIS's Flat file destination but keep getting the same error: Error 0xc0208030: Data Flow Task: The data type for "input column "image_full" (105)" is DT_IMAGE, which is not supported. Use DT_TEXT or DT_NTEXT instead and convert the data from, or to, DT_IMAGE using the data conversion component. (SQL Server Import and Export Wizard) The data type is IMAGE in SQL DB. I would like to export the image and save the same in local folder. Is their any way to perform this task using SSIS flat file destination? What is the best and easiest way to do this? What format should I be exporting to?
