  • Center text inside a circle on a canvas

    - by jax
    I have the coordinates of the center of a circle where I need to draw some text. The circle may be larger or smaller depending on the attributes I have specified. I have set the center horizontally using mTextBrush.setTextAlign(Align.CENTER);. The problem is that I can't figure out a way to center the text vertically. (See "Draw the counter" below) //Text Brush setup mTextBrush = new Paint(Paint.ANTI_ALIAS_FLAG); mTextBrush.setColor(Color.BLACK); mTextBrush.setTextSize(1/10*mMaxSize); mTextBrush.setTextAlign(Align.CENTER); mTextBrush.setStyle(Paint.Style.STROKE); private void drawSmallTimer(Canvas canvas) { //Variable cache int radiusLocalCache = this.mRadius; int cx = radiusLocalCache+(radiusLocalCache/2); int cy = radiusLocalCache-(radiusLocalCache/2); int radius = radiusLocalCache/3; //Draw the background circle canvas.drawCircle(cx, cy, radius, mBackgroundBrush); //Draw the outline stroke canvas.drawCircle(cx, cy, radius, mStrokeBrush); //Draw the counter String text = String.valueOf(mCounter); canvas.drawText(text, cx, cy, mTextBrush); }

  • Stop node containing subnodes and text in schema

    - by AndyC
    If I have some xml like this: <mynode> <mysubnode> <mysubsubnode>hello world</mysubsubnode> some more text </mysubnode> </mynode> As you can see, mysubnode contains both a subnode and some text data. What I want to know is, is it possible to prevent this happening in a schema? I don't want nodes to contain subnodes and text, just subnodes or text. Is there an option in my xsd I can specify to force this? My program to that uses this xml is written in .NET, so I'll tag it as well incase there's anything of use in .net that I can utilise for this, though I'd much rather that the issue was fixed in the schema itself. Cheers

  • SQL query to remove text within parentheses?

    - by Josh Fraser
    What is the best SQL query to remove any text within parenthesis in a mySQL database? I'd like something that works regardless of the position of the parenthesis in the text (beginning, middle, end, whatever). I don't care about keeping the text inside the parenthesis, just removing it. Thanks!

  • Problems with 'while' loop and 'for' loop when reading through file

    - by David Beckham
    I wasted plenty of hours trying to figure out the problem but no luck. Tried asking the TA at my school, but he was useless. I am a beginner and I know there are a lot of mistakes in it, so it would be great if I can get some detail explanation as well. Anyways, basically what I am trying to do with the following function is: Use while loop to check and see if random_string is in TEXT, if not return NoneType if yes, then use a for loop to read lines from that TEXT and put it in list, l1. then, write an if statement to see if random_string is in l1. if it is, then do some calculations. else read the next line Finally, return the calculations as a whole. TEXT = open('randomfile.txt') def random (TEXT, random_string): while random_string in TEXT: for lines in TEXT: l1=TEXT.readline().rsplit() if random_string in l1: ''' do some calculations ''' else: TEXT.readline() #read next line??? return #calculations return None

  • Disabling Text field with Javascript when value in drop down box is from mysql

    - by SteveJ313
    Hi I have a simple script in HTML, using a dropdown menu. When the value 1 is selected, the user can write in the text field, if value 2 is selected, it disables the text field. However, i changed the values of the dropdown menu, so that one value was from a mysql table(using PHP) and the other remained 'option value='1''. Yet now neither text field is disabled. Below is the code. `<script type="text/javascript"> function findselected() { if (document.form.selmenu.value == <?php echo $id; ?>) { document.form.txtField.disabled=true; // return false; // not sure this line is needed } else { document.form.txtField.disabled=false; // return false; // not sure this line is needed } } ` And the PHP section if(mysql_num_rows($SQL) == 1) { echo "<select name='selmenu' onChange='findselected()'>"; echo "<label>TCA_Subject</label>"; while ($row=mysql_fetch_array($SQL)) { echo "<option value='$id'>$thing</option>"; echo "<option value='2'>Choice 2</option>"; } } echo "<option value=$userid>'Choice 1'</option>"; ?> <option value='2'>Choice 2</option>"; </select> I have tried taking the second option value out of the loop, putting it into html, editing the variable in the javascript function. There is not a fault with the PHP as it is retrieving the right results and displaying it, yet the text field doesnt become disabled. Does anyone know of a possible solution? Thanks

    - by Kratz
    I'm working in AutoCAD using the ObjectARX .Net API. Is there a way to either create text using lines/curves/polylines, or explode an existing text object into lines/ect? Prefereable I would like to be able to generate linework based on an exsiting AutoCAD text style. Edit: I was able to find the source for the TxtExp command here . However its in AutoCADs own Lisp language, and I can't make heads or tails of it.

  • Restructured Text - adding title attributes to links

    - by Ant
    Hi all, I am trying to use a jquery lightbox implementation on my website that is generated from Restructured Text. The lightbox takes the title of the link around the images as the caption of the image in the lightbox display. However, I can't seem to find a way in Restructured Text of providing a title attribute on a link - does anyone know of a way of doing so. My Images are defined like so: .. image:: image001.thumb.jpg :alt: Some alt text here :target: image001.jpg So I can add an alt attribute, but not a title. A possible alternative may be to use a target as the reference like so: .. image:: image001.thumb.jpg :alt: Some alt text here :target: image1_ .. _image1: image001.jpg In this latter case, I am not sure how to add attributes to the link defined at the bottom (if it is possible at all)

  • RichTextBox text is not shown C#

    - by user271077
    using richtextbox control programatically i'm appending text to the richtextbox . richTextBox1.AppendText("hello"); somehow the text appears in the richTextBox1.Text but is not shown in the form. any idea of what might be the problem? (I checked the forecolor seems ok). Thanks in advance Edit: found the root cause (had by mistake the initializeComponent() twice. ) private void InitializeComponent() { this.richTextBox1 = new System.Windows.Forms.RichTextBox(); this.SuspendLayout(); // // richTextBox1 // this.richTextBox1.Location = new System.Drawing.Point(114, 104); this.richTextBox1.Name = "richTextBox1"; this.richTextBox1.Size = new System.Drawing.Size(100, 96); this.richTextBox1.TabIndex = 0; this.richTextBox1.Text = ""; // // Form1 // this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(284, 262); this.Controls.Add(this.richTextBox1); this.Name = "Form1"; this.Text = "Form1"; this.Load += new System.EventHandler(this.Form1_Load); this.ResumeLayout(false); } public Form1() { InitializeComponent(); InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { richTextBox1.AppendText("hello world"); }` but still curious about why did this cause this weird behavior?

  • read text file line by line and insert/update values in table

    - by I__
    i am exploring the option of whether DoCmd.TransferText will do what i need, and it seems like it wont. i need to insert data if it does not exist and update it if it does exist i am planning to read a text file line by line like this: Dim intFile As Integer Dim strLine As String intFile = FreeFile() Open myFile For Input As #intFile Line Input #intFile, strLine Close #intFile i guess each individual line will be a record. it will probably be comma separated and some fields will have a " text qualifier because within the field itself i will have commas my question is how would i read a comma delimited text file that has double quotes sometimes as text qualifiers into a table in access?

  • Relating text fields to check boxes in Java

    - by Finzz
    This program requires the user to login and request a database to access. The program then gets a connection object, searches through the database storing the column names into a vector for later use. The problem comes with implementing text fields to allow the user to search for specific values within the database. I can get the check boxes and text fields to appear using a gridlayout and add them to a panel. How do I relate the text fields to their appropriate check box? I've tried adding them to a vector, but then they can't also be added to the panel as well. I've searched for a way to name the text fields as the loop cycles through the column names, but it seems impossible to do without having them declared ahead of time. This can't be done either, as it's impossible to determine the attributes that the user will request. I just need to be able to know the names of the text fields so I can test to see if the user entered information and perform the necessary logic. Let me know if you have to see the rest of the code to give an answer, but hopefully you get the general idea of what I'm trying to accomplish. Picture of UI: try { ResultSet r2 = con.getMetaData().getColumns("", "", rb.getText(), ""); colNames1 = new Vector<String>(); columns1 = new Vector<JCheckBox>(); while (r2.next()) { colNames1.add(r2.getString(4)); JCheckBox cb = new JCheckBox(r2.getString(4)); JTextField tf = new JTextField(10); columns1.add(cb); p3.add(cb); p3.add(tf); } }

  • jquery .find to get the text in a <li>

    - by Chris
    So I have a series of 2 nested ul's. When you click on the text (which is in an a tag) in the li, my page makes that editable and adds a save button. clicking the save button needs to give me back the new text inside that li and the id of that li. The id is not a problem. I'm trying to use jQuery's .find to select that anchor tag (which is successful) but i can't seem to get the text from it. Here is an example of the first list and it's sublists. <ul class='lists'> <li class='list1'> <a class='a list' id='list1'> List 1 Name</a> <img id='savelist1id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> <ul class='list1subs'> <li class='sub1'> <a class='a sub' id='sub1id'> Sub 1 Name</a> <img id='savesub1id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> <li class='sub3'> <a class='a sub' id='sub2id'> Sub 2 Name</a> <img id='savesub2id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> <li class='sub2'> <a class='a sub' id='sub3id'> Sub 3 Name</a> <img id='savesub3id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> </ul> </li> </ul> Here's the code for identifying which save button you clicked. function SaveName(parentid){ $('li').find('a').each(function(){ if (this.id == parentid){ alert(this.id+' '+this.text) } } }); I am wanting this.text to show me the text inside the anchor tags. Help, please?
