  • Determine when and which character is added or deleted in a Text Box.

    - by Alon
    I have a simple text box in a WPF application. I need to know when a character was added/deleted in the text box, which character and where it was added or deleted. I thought to use the TextBox.KeyDown event, but it has some problems: I can't know where the character was added or deleted. I have no idea how to determite which character was added (from the KeyEventArgs). Any ideas? I don't care to use a completely different solution from what I thought. In addition, I've just started this project so I don't care to use Windows Forms instead of WPF if your solution requires it. Thank you.

  • How to modify the Title Bar text for SQL Server Management Studio?

    - by DaveDev
    Sometimes I keep multiple instances of SQL Server Management Studio 2005 open. I might have the dev database open in one, and the production database open in another. These appear in the Windows task bar with the text "Microsoft SQL Serve...", which means it's impossible to differentiate between them unless I open the window and scroll the Object Explorer up to see what server the window is actually connected to. Is ther any way that I can get the window to display the server name first, and then the name of the application? Like "Dev-DB.database_name - Microsoft SQL Serve..." or whatever?

  • How can we store password other than plain text?

    - by Eric
    I've found numerous posts on stackoverflow on how to store user passwords. However, I need to know what is the best way to store a password that my application needs to communicate with another application via the web? Currently, our web app needs to transmit data to a remote website. To upload the data, our web app reads the password from a text file and creates the header with payloads and submits via https. This password in plain text on the file system is the issue. Is there any way to store the password more securely? Thanks!

  • text watermark on website? how to do it?

    - by Tim
    I am a C++/C# developer and never spent time working on web pages. I would like to put text (randomly and diagonally perhaps) in large letters across the background of some pages. I want to be able to read the foreground text and also be able to read the "watermark". I understand that is probably more of a function of color selection. I have been unsuccessful in my attempts to do what I want. I would imagine this to be very simple for someone with the web design tools or html knowledge. Any links or sample code? Thanks

  • Android: How to set the contents of a Edit text from a Button click?

    - by primal
    Hi, I am a rookie to android. I am thinking of implementing a simple calculator in android to get a hold of the basics in android. I want to display a keypad with numbers and mathematical operations and when the user presses the keys the corresponding number is displayed in edit text. I tried using gettext() and updating the contents of edit text but it shows just the contents of pressed button. Also how do I read the contents of button so as to do mathematical operations in code? Any help would be much appreciated. regards, Primal

  • Read and write .NET Objects in SQL Database without serialization.

    - by Mohit
    Hello, I have a small query. I need to create a Caching Service of my own that will write and read .NET Objects to and from the Database. Now, I have achieved that with the help of Binary Serialization. But the Problem is I need to deliberately marked my objects as [Serializable], which makes me think that what if someone will try to add an object which is not marked as [Serializable]. Thus, I need to find a way to read and write Objects to Database without Serialization. I have one thought too.. As we all know Session can store any object in it. Now, we can make sessions to be stored in the DB, outproc. What mechanism it uses to store these objects without serializing or deserializing. Any help will be highly appreciated. Thanks. M.B

  • How can I make text in a UILabel non-centered?

    - by Sheehan Alam
    I have a UILabel: descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 30, 130, 150)]; [descriptionLabel setFont:[Utils getSystemFontWithSize:14]]; [descriptionLabel setBackgroundColor:[UIColor clearColor]]; [descriptionLabel setTextColor:[UIColor whiteColor]]; descriptionLabel.numberOfLines = 0; descriptionLabel.lineBreakMode = UILineBreakModeWordWrap; [self addSubview:descriptionLabel]; If the text is only 1 line long it will appear in the middle of the label. Is there anyway I can have the text display from the top left corner of the label instead of the middle center?

  • how can I get jquery.sIFR plugin to display sIFR-alternate text for print?

    - by apeBoy
    I'm struggling with this. I've used the jquery sIFR plugin as opposed to sIFR it prevented conflicts with other jquery I am using on my pages. It works fine in its prime function: replacing html text with Flash. However, the .sIFR-alternate class is given an inline style of 'opacity: 0' which persists when flashblock is on. So alternate text does not appear. Neither does it appear when printng the page (yes I have included styles for sIFR-print). I've tried replacing the opacity:0 inline style with display: none but this causes height issues with the output flash. Any one else had this or have any ideas?

  • How can I have centered text and right-aligned image in the same element?

    - by Ethan
    I have some th elements with text in them that should be centered and they also contain images: The up/down arrow graphic is a separate image. My question is, what is the simplest reliable way to position that image over to the right side of the th element while keeping the text centered? I'm open to using jQuery/JavaScript if there's a reasonably simple way to do it. One caveat: I need the up/down graphic to be a separate image, not part of the header background. <th> Title <img src='/images/sort_unsorted.jpg' /> </th>

  • Is it a good practice to perform direct database access in the code-behind of an ASP.NET page?

    - by patricks418
    Hi, I am an experienced developer but I am new to web application development. Now I am in charge of developing a new web application and I could really use some input from experienced web developers out there. I'd like to understand exactly what experienced web developers do in the code-behind pages. At first I thought it was best to have a rule that all the database access and business logic should be performed in classes external to the code-behind pages. My thought was that only logic necessary for the web form would be performed in the code-behind. I still think that all the business logic should be performed in other classes but I'm beginning to think it would be alright if the code-behind had access to the database to query it directly rather than having to call other classes to receive a dataset or collection back. Any input would be appreciated.

  • Reading data from a MySQL database into a HTML Table?

    - by Michael McKay
    So i am working on a project and need some advice. I have a MySQL database that stores events, i know how to code this functionality in PHP but im just stuck of a few specifics. As the project that I am creating is a timetable, the most important attributes are the day of the event, starting time and finishing time. Once i have read this data from the MYSQL database using my PHP script, how do i go about inserting these events in to a html timetable? Lets say i have record like below in my events table: Event ID = 01 Event Day = Monday Event Start = 12:00 Event End = 14:00 How would I then put that into a html table, bearing in mind that i may have mutiple events for a day?

  • Confusion using MYSQLI

    - by user1020069
    I just started using mysqli API for PHP. Apparently, every time an object of the class MYSQLI is instantiated, it can setup a connection to the database as it connects to the server unlike mysql_connect, which connects to the server first and then you are required to specify the database to query. Now this is a good problem if the db exists, in my case, the db does not exist on the first ever connection to the server/execution of the problem, hence I must connect without specifying the database, which is fine, since the msyqli constructor does not make this database mandatory. My challenge is essentially, how do I check if the database exists before attempting the first connection. The only way to really do this would be to establish a conection to the server and then use the result of the following query to gauge if the database exists: SELECT COUNT(*) AS `exists` FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMATA.SCHEMA_NAME="dbname" ; If this returns true, then the database exists, but now the challenge is how do I get the mysqli object to query this database rather than having to prefix the name of the database in the query. Thanks much

  • How do I place an image centered in a DIV and text to the right? Overflow problems

    - by user2218041
    I have a div container where I want to put in a centered image and a small description to the right. The specifications are: The image should have a bottom margin of 35px. The image should always show fully on the screen, so it resizes when the screen does. It should have the biggest size possible, but never be cropped and never use scrollbars. The image should be centered with respect to the container, with the text showing on the right margin. The text should be left-aligned horizontally, center-aligned vertically and have a 30px separation from the image. I've tried using a table in the container and using divs, but I can't find a clean solution. I can show you the non-working code I've tried on request.
