    - by Tom
    In my HTML document, I have a table with two columns and multiple rows. How can I increase the space in between the first and second column with css? I've tried applying "margin-right: 10px;" to each of the cells on the left hand side, but to no effect.

  • How do I locate a particular word in a text file using .NET

    - by cmrhema
    I am sending mails (in asp.net ,c#), having a template in text file (.txt) like below User Name :<User Name> Address : <Address>. I used to replace the words within the angle brackets in the text file using the below code StreamReader sr; sr = File.OpenText(HttpContext.Current.Server.MapPath(txt)); copy = sr.ReadToEnd(); sr.Close(); //close the reader copy = copy.Replace(word.ToUpper(),"#" + word.ToUpper()); //remove the word specified UC //save new copy into existing text file FileInfo newText = new FileInfo(HttpContext.Current.Server.MapPath(txt)); StreamWriter newCopy = newText.CreateText(); newCopy.WriteLine(copy); newCopy.Write(newCopy.NewLine); newCopy.Close(); Now I have a new problem, the user will be adding new words within an angle, say for eg, they will be adding <Salary>. In that case i have to read out and find the word <Salary>. In other words, I have to find all the words, that are located with the angle brackets (<). How do I do that?

  • PHP Form Sending Information to Limbo!

    - by drew
    I was told my client's quote form has not been generating very many emails. I have learned that although the form brings you to a confirmation page, the information never reaches the recipient. I have altered the code so it goes to my office email for testing purposes. If I post code for the form elements below, would someone be able to spot what the problem might be? Thank you very much! Link to the quote page is http://autoglass-plus.com/quote.php First is the form itself: <form id="quoteForm" name="form" action="form/index.php" method="post"> <fieldset> <p> <strong>Contact Information:</strong><br /> </p> <div> <label for="firstname">First Name:<br /> </label> <input type="text" size="30" name="firstname" class="txt" id="firstname" /> </div> <div> <label for="lastname">Last Name:<br /> </label> <input type="text" size="30" name="lastname" class="txt" id="lastname" /> </div> <div> <label for="address">Address:<br /> </label> <input type="text" size="30" name="address" class="txt" id="address" /> </div> <div> <label for="city">City:<br /> </label> <input type="text" size="30" name="city" class="txt" id="city" /> </div> <div> <label for="state">State:<br /> </label> <input type="text" size="30" name="state" class="txt" id="state" /> </div> <div> <label for="zip">Zip:<br /> </label> <input type="text" size="30" name="zip" class="txt" id="zip" /> </div> <div> <label for="label">Phone:<br /> </label> <input type="text" size="30" name="phone" class="txt" id="label" /> </div> <div> <label for="email">Email:<br /> </label> <input type="text" size="30" name="email" class="txt" id="email" /> </div> <p><br /> <b>Insurace Information</b></p> <p><i>Auto Glass Plus in an Approved Insurance Vendor.

  • iPhone plist data, large amounts of text and return key?

    - by user278342
    Basicly iv built my app using a plist. But with the data there is a few times when I need to press return and start a new line. The return key doesn't work in the plist. If I did it the older way it would be \n\n but that doesn't work either. Is there a obvious way I'm overlooking? Or will it be a case off just pressing the space bar allot? Thanks

  • Thin-border on WPF window?

    - by Rezzie
    I'd like to create a window, using WPF, that has a thin border all the way around the form - i.e. no space for the title bar with the icon/caption and min/max/close buttons. For example, the "extra" icons form of the new Windows 7 taskbar: How can I do this with WPF (I don't mind resorting to the Win32 API, if not supported natively by WPF)?

  • ActionScript Measuring 3D Depth

    - by TheDarkIn1978
    i'm having a difficult time understanding how to control the z property of display objects in a 3D space. i know how depth works, but what i don't understand is how i can get the maximum depth, or the number at which the display object just disappears into the background. i assume depth is based on the stage's width and height, and that is why assigning the same depth of the same display object appars mismatched with different stage sizes. so how can i appropriately measure depth?

  • Why do I get rows of zeros in my 2D fft?

    - by Nicholas Pringle
    I am trying to replicate the results from a paper. "Two-dimensional Fourier Transform (2D-FT) in space and time along sections of constant latitude (east-west) and longitude (north-south) were used to characterize the spectrum of the simulated flux variability south of 40degS." - Lenton et al(2006) The figures published show "the log of the variance of the 2D-FT". I have tried to create an array consisting of the seasonal cycle of similar data as well as the noise. I have defined the noise as the original array minus the signal array. Here is the code that I used to plot the 2D-FT of the signal array averaged in latitude: import numpy as np from numpy import ma from matplotlib import pyplot as plt from Scientific.IO.NetCDF import NetCDFFile ### input directory indir = '/home/nicholas/data/' ### get the flux data which is in ### [time(5day ave for 10 years),latitude,longitude] nc = NetCDFFile(indir + 'CFLX_2000_2009.nc','r') cflux_southern_ocean = nc.variables['Cflx'][:,10:50,:] cflux_southern_ocean = ma.masked_values(cflux_southern_ocean,1e+20) # mask land nc.close() cflux = cflux_southern_ocean*1e08 # change units of data from mmol/m^2/s ### create an array that consists of the seasonal signal fro each pixel year_stack = np.split(cflux, 10, axis=0) year_stack = np.array(year_stack) signal_array = np.tile(np.mean(year_stack, axis=0), (10, 1, 1)) signal_array = ma.masked_where(signal_array > 1e20, signal_array) # need to mask ### average the array over latitude(or longitude) signal_time_lon = ma.mean(signal_array, axis=1) ### do a 2D Fourier Transform of the time/space image ft = np.fft.fft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log(mgft) log_mgft= np.log(mgft) Every second row of the ft consists completely of zeros. Why is this? Would it be acceptable to add a randomly small number to the signal to avoid this. signal_time_lon = signal_time_lon + np.random.randint(0,9,size=(730, 182))*1e-05 EDIT: Adding images and clarify meaning The output of rfft2 still appears to be a complex array. Using fftshift shifts the edges of the image to the centre; I still have a power spectrum regardless. I expect that the reason that I get rows of zeros is that I have re-created the timeseries for each pixel. The ft[0, 0] pixel contains the mean of the signal. So the ft[1, 0] corresponds to a sinusoid with one cycle over the entire signal in the rows of the starting image. Here are is the starting image using following code: plt.pcolormesh(signal_time_lon); plt.colorbar(); plt.axis('tight') Here is result using following code: ft = np.fft.rfft2(signal_time_lon) mgft = np.abs(ft) ps = mgft**2 log_ps = np.log1p(mgft) plt.pcolormesh(log_ps); plt.colorbar(); plt.axis('tight') It may not be clear in the image but it is only every second row that contains completely zeros. Every tenth pixel (log_ps[10, 0]) is a high value. The other pixels (log_ps[2, 0], log_ps[4, 0] etc) have very low values.

  • html horizontal scrolling

    - by mp
    Hi, i have a simple css example, and i can't understand the behavior of one of my divs, when the horizontal scroll is displayed. so...when my browser window needs to display the horizontal scroll(when the window width is less than my div "content" width(1024px)), my div "footer" (that have the same "content's" parent and 100% width), seems to get an "extra blank space" on the right side. this space grows when I reduce the width of the window. any ideas about how can i get it off, or why it happens??thanks! heres my code: css: <style type="text/css"> html, body { height: 100%; width:100%; font-family:"Arial Black", Gadget, sans-serif; font-size:11px; font-variant:normal; } * { margin: 0; } .wrapper { min-height: 100%; height: auto !important; height: 100%; margin: 0 auto -4em; } #content{ width:1024px; margin:0px auto; background-color:#990; height:780px; } .footer, .push { height: 4em; width:100%; } #footer-content{ height:10px; background-color:#09F; width:100%; } </style> html: <body> <div class="wrapper"> <div id="content"> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.

  • What is the best way to produce a tilde in LaTeX for a website?

    - by vgm64
    Following the previous questions on this topic, when you produce a website in LaTeX what is the best way to produce a url that contains a tilde? \verb produces the upper tilde that does not read well, and $\sim$ does not copy/pase well (adding a space when I do it). Solutions? It seems like this should be one of those things that has a very easy fix... if it doesn't, why not?

  • Why does setting this member in C fail?

    - by Lee Crabtree
    I'm writing a Python wrapper for a C++ library, and I'm getting a really weird when trying to set a struct's field in C. If I have a struct like this: struct Thing { PyOBJECT_HEAD unsigned int val; }; And have two functions like this: static PyObject* Thing_GetBit(Thing* self, PyObject* args) { unsigned int mask; if(!PyArg_ParseTuple(args, "I", &mask) Py_RETURN_FALSE; if((self->val & mask) != 0) Py_RETURN_TRUE; Py_RETURN_FALSE; } static PyObject* Thing_SetBit(Thing* self, PyObject* args) { unsigned int mask; bool on; if(!PyArg_ParseTuple(args, "Ii", &mask, &on)) Py_RETURN_FALSE; if(on) thing->val |= mask; else thing->val &= ~mask; Py_RETURN_TRUE; } Python code that calls the first method works just fine, giving back the value of the struct member. Calls to the SetBit method give an error about an object at address foo accessing memory at address bar, which couldn't be "written". I've poked around the code, and it's like I can look at the value all I want, both from C and Python, but the instant I try to set it, it blows up in my face. Am I missing something fundamental here?

  • How to gray out HTML form inputs?

    - by typoknig
    What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JScript) or can I use PHP (which I am more familiar with)? EDIT: After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly this one) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here? <label>Mailing address same as residental address</label> <input name="checkbox" onclick="disable_enable() "type="checkbox" style="width:15px"/><br/><br/> <script type="text/javascript"> function disable_enable(){ if (document.form.mail_street_address.value==1) document.form.mail_street_address.value=0; //document.form.mail_street_address.disabled=true; //document.form.mail_city.disabled=true; //document.form.mail_state.disabled=true; //document.form.mail_zip.disabled=true; else document.form.mail_street_address.value=1; //document.form.mail_street.disabled=false; //document.form.mail_city.disabled=false; //document.form.mail_state.disabled=false; //document.form.mail_zip.disabled=false; } </script>

  • Entity Framework and stored procedure returning temp table Issues

    - by kaplooeymom
    (Disclaimer - I'm not the database designer. I'm just the poor developer what has to make this work.) There are 17 (at the moment) tables with identical structure - name, address, phone number. Given a phone number, I have to check to see if there's a matching entry in any of the tables, then return that address. So, I created a view to get the list of tables (there's a ref table that holds that info), then I created a stored procedure to create a temp table, using cursors, check each table in the view for the phone number, using sql concatenation. If a record is found, insert it into the temp table. return the rows from the temp table. This all works in straight T-SQL. Now, I'm trying to use Entity Framework 4+ to call the stored procedure. But the function import interface won't generate columns. It says return type = none, and the LINQ code expects an int and won't compile. Any ideas on how to make this work? I know I can move the check tables part to code, if I absolutely have to, but I'd rather have the above method work.

  • Prevent image cropping when making sprites from gif

    - by OSaad
    Hey guys I've tried several tools (imagemagic, gif2png, Nconverter) to extract frames to make sprites from a .gif image that i have. I get the .pngs just fine, but they'r not the same size, some are 50x65 some 43x65 some 50x70, Which really screws any attempts at a descent animation. So is there a way to prevent this cropping or programmatically add extra transparent space to smaller ones and make them all the same size? Thanks.

  • Getting a users Facebook profile url

    - by Greg Pabst
    I am creating a registry site so similar people can find each other easily. I don't want to use Facebook Connect as the primary log in method or use Facebook to store their information. I'll be creating a database on my end to store that info. For security reasons I won't be displaying the users address, phone number or email address so I wanted to provide the next best way for people to connect with each other, this is where Facebook comes in. Normally I would just ask them to type their Facebook URL in a text box but I don't think most people know what their url is which is why I think I need to use Facebook Connect. So here is my idea..when the users signs up there is a check box that when checked signifies they are allowing people to find them on Facebook. I assume once they click the register button that a Facebook Connect popup will show up asking for permission to access their Facebook account. When they "allow" it, then I can get their profile url. All I need is their Facebook profile url, I don't want any other Facebook features or information. Is Facebook Connect the best thing to use for this scenario? Is there an easier way? Several months ago on the Facebook Connect site their used to be examples of doing this, but all the documentation has been rearranged and changed and I can't seem to find the information. Any help you can provide would be great!

  • bash: expanding variables with spaces

    - by adam n
    i have a file called physics 1b.sh in bash, if i try x="physics 1b" grep "string" "$x".sh grep complains: grep: physics 1b: No such file or directory. However, when i do grep "string" physics\ 1b.sh it works fine. So i guess the problem is something to do with the variable not being expanded to include the backslash that grep needs to recognize the space. How do i get this to work? using bash 3.2, mac os 10.6.
