  • Latex: Text cannot be placed below image

    - by Frederik Wordenskjold
    I love latex! But sometimes, it does not love me... I'm having a problem with an image and some text. I have this code: Some text...\\ \begin{figure}[ht] \centering \includegraphics[scale=0.75]{picture.jpg} \caption{The caption} \label{fig:picture} \end{figure} Some more text... Basically, I want this: Some text. (Above image in the code) [end of page / new page] image Some more text. (Below the image in the code) [start of new section] But, what the above code gives me is this: Some text. (Above image in the code) Some more text. (Below the image in the code) [end of page / new page] image [start of new section] Latex insists on putting everything but a new section above the image even though its below the image in the code. Its probably because the image floats on top - but whats my alternative? There's not enough space on the first page to display the image there, to I cannot use [h] as the float-alignment. I can "hack it", by creating an empty new section, like \section*{}, but this creates some white-space, which looks weird. Any suggestions?

  • How to download .txt file from a url?

    - by Colin Roe
    I produced a text file and is saved to a location in the project folder. How do I redirect them to the url that contains that text file, so they can download the text file. CreateCSVFile creates the csv file to a file path based on a datatable. Calling: string pth = ("C:\\Work\\PG\\AI Handheld Website\\AI Handheld Website\\Reports\\Files\\report.txt"); CreateCSVFile(data, pth); And the function: public void CreateCSVFile(DataTable dt, string strFilePath) { StreamWriter sw = new StreamWriter(strFilePath, false); int iColCount = dt.Columns.Count; for (int i = 0; i < iColCount; i++) { sw.Write(dt.Columns[i]); if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); // Now write all the rows. foreach (DataRow dr in dt.Rows) { for (int i = 0; i < iColCount; i++) { if (!Convert.IsDBNull(dr[i])) { sw.Write(dr[i].ToString()); } if (i < iColCount - 1) { sw.Write(","); } } sw.Write(sw.NewLine); } sw.Close(); Response.WriteFile(strFilePath); FileInfo fileInfo = new FileInfo(strFilePath); if (fileInfo.Exists) { //Response.Clear(); //Response.AddHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name); //Response.AddHeader("Content-Length", fileInfo.Length.ToString()); //Response.ContentType = "application/octet-stream"; //Response.Flush(); //Response.TransmitFile(fileInfo.FullName); } }

  • Detect a file is closed

    - by User1
    Is there a simple way to detect when a file for writing is closed? I have a process that kicks out a new file every 5 seconds. I can not change the code for that process. I am writing another process to analyze the contents of each file immediately when it is created. Is there a simple way to watch a certain directory to see when a file is no longer opened for writing? I'm hoping for some sort of Linux command.

  • MS-Access nested DIR - check if a file exists elsewhere whilst looping through a folder

    - by David Carle
    I have used the DIR() command in Microsoft Access 2003 to loop through the files in folder A. This works fine, but I need to check if each file also exists in another location (folder B), and only process the file if it doesn't exist in folder B. The problem is that checking for the file existing in folder B also uses the DIR() function and this then resets or confuses the original one, with the result that no further files are found in folder A. Is there a way to check if a file exists without using DIR? Or, is there a way to have a separate instance of DIR? I suppose I could build a list of the files in folder A into an array and then process the entries in the array, but this seems rather 'clunky' Any suggestions for a better solution? Thanks

  • change extension obfuscate XML file contents

    - by FFish
    I have SlideShowPro, a Flash photo app that loads an XML file with the paths to the images. Now I don't want people to go sniff in the XML file to get to the images. I tried changing the file images.xml to spacer.gif and it seems to work fine. But I would like to know if I would run into any problems changing the extension. btw already used a few techniques to make the images not so accessible, I know there is no bulletproof solution. Obfuscating the XML file is just another trick..

  • Zoom image to pixel level

    - by zaf
    For an art project, one of the things I'll be doing is zooming in on an image to a particular pixel. I've been rubbing my chin and would love some advice on how to proceed. Here are the input parameters: Screen: sw - screen width sh - screen height Image: iw - image width ih - image height Pixel: px - x position of pixel in image py - y position of pixel in image Zoom: zf - zoom factor (0.0 to 1.0) Background colour: bc - background colour to use when screen and image aspect ratios are different Outputs: The zoomed image (no anti-aliasing) The screen position/dimensions of the pixel we are zooming to. When zf is 0 the image must fit the screen with correct aspect ratio. When zf is 1 the selected pixel fits the screen with correct aspect ratio. One idea I had was to use something like povray and move the camera towards a big image texture or some library (e.g. pygame) to do the zooming. Anyone think of something more clever with simple pseudo code? To keep it more simple you can make the image and screen have the same aspect ratio. I can live with that. I'll update with more info as its required.

  • Trouble getting Flash socket policy file to work.

    - by Alex
    Basically I'm using Flash to connect to a Java server. Despite my Java application replying to the , in the Flash debug log it lists (not sure about the order as there are lots): * Security Sandbox Violation * Connection to 192.168.1.86:4049 halted - not permitted from http://127.0.0.1:8888/Current/wander.swf Warning: Timeout on xmlsocket://192.168.1.86:4049 (at 3 seconds) while waiting for socket policy file. This should not cause any problems, but see http://www.adobe.com/go/strict_policy_files for an explanation. Error: Request for resource at xmlsocket://192.168.1.86:4049 by requestor from http://127.0.0.1:8888/Current/wander.swf is denied due to lack of policy file permissions. What I don't understand is, the server (port 4049) receives the request, outputs the policy file and then closes the connection, surely it shouldn't time out? The policy file I'm using is: <?xml version="1.0"?> <cross-domain-policy><allow-access-from domain="*" to-ports="*" /> </cross-domain-policy>

    - by Brian
    Hi, I have a batch file that is Run when a selfextraction file is executed. The self extracted files must be copied to to specefic place on the harddisc. In the batch file the user is asked where the path is (if it's not located the default place) Part of the batch file: @ECHO OFF IF EXIST "C:\Program Files\program\program.exe". ( set PROGRAMPATH=C:\Program Files\ ) ELSE ( echo Program folder was not found. Please enter the path for Program set /p PROGRAMPATH=Path: ) echo Copying data to "%PROGRAMPATH%"... copy /Y "*.txt" "%PROGRAMPATH%" Now for my question. If a user then enters a new path, is it possible to save that path. So when he executes the self extraction packagde again, it could remember that new path?

  • File permissions changed between OS X and Windows

    - by Horace Ho
    I zipped a rails project from OS X and sent it to a colleague who works on Windows. He updated the source, zipped the whole project folder and sent the zip file back to me. After unzipping the project, I found that the file permissions information is kind of lost. For example, the script/server is changed from -rwxr-xr-x to -rw-r--r--. Is there a way to preserver the file permission flags, when transferring files between mac and windows? Thanks

  • Php writing to file - empty ?

    - by The Devil
    Hey, I've been struggling with writing a single string into a file. I'm using just a simple code under Slackware 13: $fp = fopen('/my/absolute/path/data.txt', 'w'); fwrite($fp, 'just a testing string...'); fclose($fp); The file gets created (if it's not already created) but it's empty ?! The directory in which this file is written is owned by apache's user & group (daemon.daemon) and has 0777 permissions. This has never happened to me before. I'm curious what's the reason I'm not able to write inside the file ? Thanks in advance.

  • PHP File Upload, files disappearing from /tmp before move_uploaded_files

    - by Bowen
    Hi, I have a very basic upload script, probably lifted straight off the php.net/move_upload_files function page. move_uploaded_file() is failed because it cannot find the tmp file in the tmp folder. But I KNOW that it is being put there, but is removed before move_upload_file() can deal with it in my script. I know it is being put there since I can see a file in there when a large file is being posted to the server. Also $_FILEScontains correct details for the file I have just uploaded. Had anyone have any idea why the temporary file is being removed from /tmp before I have a chance to handle it? Here is the basic code that I am using. if(move_uploaded_file($_FILES['userfile']['tmp_name'], $upload_file)) { $result['error'] = 'false'; $result['file_loc'] = $upload_file; } else { $result['error'] = 'true'; } The output of print_r($_FILES) looks like [userfile] => Array ( [name] => switchsolo.png [type] => image/png [tmp_name] => /tmp/phpIyKRl5 [error] => 0 [size] => 6690 ) But /tmp/phpIyKRl5 simply isn't there.

    I am using fcntl locks in C on linux and have a dilemma of trying to delete a file that may possibly be locked from other processes that also check for the fcntl locking mechanism. What would be the preferred way of handling this file which must be deleted, (Should I simply delete the file w/o regard of other processes that may have reader locks or is there a better way)? Any help would be much appreciated.

  • Java Can't Find File when Running through Eclipse

I can compile and run the application from the command line just fine; the problem only occurs in Eclipse, with more than one project and application. Is there a setting I need to change in the run configurations or build paths to get it to find the file correctly?
