I have a Portable Bridge Notation formatted-file that I have to work with. I have already a few simple examples working by using indexing and substrings extracting what I need and I suppose for this PBN business it would suite me well since it isn't run too often. If I one the other hand would run that code like all the time (thinking of working with vCards) then I am worried about memory usage under high workload because of the high amout of temporary string variables created from all substrings and splits.
There are two other options available that I know of. Regex and StringReader / TextReader and I wanted some general opinion on what to use.
Intended usage is to extract to objects and serialize to json so that I can more easily work with or persist this information. Hell if it's fast enough I might even do it on the fly.
I've used the substring feature before, but I am struggling with this one since I only want the page names which are on the right hand side, I basically want to chop of everything else (folder paths).. all I want to end up with is default.aspx, gallery.aspx and demo.aspx
I have a datalist that is populated via and SqlDataSource. Code is VB
I am trying to extract two Values from the Item Templete and add them together. Then I want to add a new Label to the item template with the sum of the two added values.
I am able to to this using a GridView but no success with the datalist
i am using the below code for extracting paragraph for matching string.
[code]...
i am getting correct result,but i am getting breakable words in starting and ending paragraphs like "...ing regions uses the and Boolean connector to specify the region so narr..."
The above code generated Option Strict On disallows implicit conversions from 'String' to 'Integer' error under the Item("Address") I don't know what i did wrong...
The task is: given a web application that returns a table with pagination, do a software that "reads and parses it" since there is nothing like a webservice that provides the raw data. It's like a "spider" or a "crawler" application to steal data that is not meant to be accessed programmatically.
Now the thing: the application is made with standart aspx webform engine, so nothing like standard URLs or posts, but the dreadful postback engine crowded with javascript and non accessible html. The pagination links call the infamous javascript:__doPostBack(param, param) so I think it wouldn't even work if I try even to simulate clicks on those links.
There are also inputs to filter the results and they are also part of the postback mechanism, so I can't simulate a regular post to get the results.
I was forced to do something like this in the past, but it was on a standard-like website with parameters in the querystring like pagesize and pagenumber so I was able to sort it out.
Anyone has a vague idea if this is doable, or if I should tell to my boss to quit asking me to do this retarded stuff?
EDIT: maybe I was a bit unclear about what I have to achieve. I have to parse, extract and convert that data in another format - let's say excel - and not just read it. And this stuff must be automated without user input. I don't think Selenium would cut it.
EDIT: I just blogged about this situation. If anyone is interested can check my post at [URL] and comment about that.
i'm currently doing a shopping website. The customer will have to selected the item they want to buy and it will appear in the detail view when they click add in the grid view. I need the info inside the detail view to be insert into a database call Orderlist.
i've try using INSERT INTO OrderList (ProductName, Price,) VALUES (@ProductName, @Price) but it don't seems to work.
Was it because i can't insert it like this as it is detailview? This method can work if is Textbox instead of detailview.
i have a gridview of 8 columns.I need to extract the data row by row from the the first(Message) and the last(phone_no) column and to be inserted into my sql table named massMessage.I have the codes here. Apparently im able to only extract the phone_no. My message wasnt inserted.
protected void btnSave_Click(object sender, EventArgs e) { foreach (GridViewRow gvr in GridView2.Rows) //loop through GridView
Im writing a bit of code that will extract the contents of a gridview to excel. I have all the parts working except for one. In my page_load i fetch the data from the database and then have the user select some options which filters the data and then the gridview gets populated. The problem im having is that the Response call doesnt seem to get the data from the gridview if i enclose the database fetch command within if not page.ispostback in the page_load
I have some test pages where i just fetched the data from the database bound it in a gridview in the Page_load. then on a button click export the data in the gridview to excel. Works fine if i DONT enclose the fetch command within not page.ispostback but outputs an empty excel file if i do.
Now i have to use not page.ispostback in the actual webpages because the users have to make selections which will filter the original dataset. How do i get this to work?
The page is also implementing AJAX if that helps. Here's an example of what i have:
I have a dataGrid with ButtonColumns in my asp page and I would like to do the following to:
When a row is clicked, I want to be able to:
1 - Hide all rows and display only the clicked row dynamically/on the fly.
trying to loop thru the datagrid and display only the Row index passed by the OnITemComman - but unsure of how to do it.
2 - Extract the row values (all cells in the row) to use as parameters in a query.
Used many ways of many examples but i always get a blank value. Managed to get the button text in the class but i need the full row values not just the cell clicked.
I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)
i have a database with several paths looking like the one below

What i aim to do is load the images into a gallery control (if one exist)the users viewing the images should be able to do either of the following:
-Double click on an image to see it bigger or some large predefined size.(thats the viewing part of it) -Select those images the want and then extract it as a single PDF file to any location on the user machine. -print all selected images. -Remove all selected images from the gallery as well as the image path from the database.
I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I've noticed that VS2008 removes the "none" option in the properties -> connection dropdownlist after you have modified a LinqToSql class where the "none" option was previously specified.So if i create a LinqToSql class, drag some db tables in, then set the connection to "none" in the properties window, save, then make a change to the db tables i've dragged into the class, i can't get it to go back to "none" again.I've noticed this behavior sporadically, not all the time. Havent isolated when it happens yet.The none option is required if you want to save your connection string in the web.config, and not in the designer.cs class or the .dbml file.
This may be something simple, but I am completely new to ASP.NET. I have been reading some tutorials based on W3Schools, and I have copied one of the files and tried to play with it by changing an element with a value to storing that same value in the attribute. Here is the edited XML (my.xml):
Is there a reliable way to extract text from PDF? The first thought that comes to mind is that PDF may have multiple columns and the extraction mechanism needs to know the logical structure somehow. I understand that some PDF docs are "tagged" but I'd need to support pretty much any PDF document.
public void ZipExtract(Stream inputStream, string outputDirectory) { using (ZipFile zip = ZipFile.Read(inputStream)) { Directory.CreateDirectory(outputDirectory); zip.ExtractSelectedEntries("name=*.jpg,*.jpeg,*.png,*.gif,*.bmp", " ", outputDirectory, ExtractExistingFileAction.OverwriteSilently);
[Code]....
I try to read zip archive from stream and extract files. Got the following exception in the line "using (ZipFile zip = ZipFile.Read(inputStream))" : ZipEntry::ReadDirEntry(): Bad signature (0xC618F879) at position 0x0000EE19. how to handle this exception?
I found an application that interacts with one of googles APIs that sends requests to the API and returns results to the web page. The owner of this app has made it publicly available and even though it is hosted on his server, it acts directly with the api from anyones browser. The source code in page source is available but since I dont know javascript, it is meaningless to me.
I would like to create an app that calls this web app and have it send requests to the API, and have the results parsed to a database. Would this be possible?
I have very little ASP experience and since trying to work through accessing the API itself is complicated since it involves using oAuth protocol and I am having a hard time with this with not much sample code available.
If this is possible, how can I get access to the results from this web app?
