  • problem with sIFR 3 not displaying in IE just getting XXX

    - by user288306
    I am having a problem with sIFR 3 not displaying in IE. I get 3 larges black XXX in IE yet it displays fine in Firefox. I have checked i do have the most recent version of flash installed correctly. Here is the code on the page <div id="features"> <div id="mainmessage_advertisers"><h2>Advertisers</h2><br /><br /><h3><a href="">Reach your customers where they browse. Buy directly from top web publishers.</a></h3><br /><br /><br /><a href=""><img src="img/buyads.gif" border="0"></a></div> <div id="mainmessage_publishers"><h2>Publishers</h2><br /><br /><h3>Take control of your ad space and start generating more revenue than <u>ever before</u>.</h3><br /><br /><br /><a href=""><img src="img/sellads.gif" border="0"></a></div> </div>` Here is the code from my global.css #mainmessage_advertisers { width: 395px; height: 200px; padding: 90px 50px; border: 1px; float: left; } #mainmessage_publishers { width: 395px; height: 200px; padding: 90px 50px; float:

  • LinkedHashMap vs HashMap != LinkedList vs ArrayList

    - by Markos Fragkakis
    I have read that LinkedHashMap has faster iteration speed than HashMap because its elements are doubly linked to each other. Additionally, because of this, LinkedHashMap is slower when inserting or deleting elements. Presumably because these links also need to be updated. Although I can see an analogy to LinkedList vs ArrayList, in that the elements of LinkedList are also doubly-linked, I read that it iterates slower than ArrayList, and has faster insertion and deletion times. Why is this? Perhaps I am making a mistake somewhere? Cheers1

  • WinForms Web Browser control forcing refocus?

    - by Corey Ogburn
    I'm trying to automate a web process where I need to click a button repeatedly. When my code "clicks" that button (an HtmlElement obtained from the WebBrowser control I have on my form) then it brings focus back to my application, more specifically the WebBrowser control. I wish to better automate this process so that the user can do other things while the process is going on, but that can't happen if the window is unminimizing itself because it's attaining focus. The code associated with the clicking is: HtmlElement button = Recruiter.Document.GetElementById("recruit_link"); button.InvokeMember("click"); I've also tried button.RaiseEvent("onclick") and am getting the exact same results, with focus problems and all. I've also tried hiding the form, but when the InvokeMember/RaiseEvent method is called, whatever I was working on loses focus but since the form is not visible then the focus seems to go nowhere. The only non-default thing about the webbrowser is it's URI being set to my page and ScriptErrorsSuppressed being set to True.

  • dojo/dijit and Printing

    - by Kitson
    I want to be able to provide a button to my users to just print a particular portion of my dojo/dijit application. There seems to be a general lack of documentation and examples when it comes to printing. For example, I have a specific dijit.layout.ContentPane that contains the content that I would like to print, but I wouldn't want to print the rest of the document. I have seen some pure JavaScript examples on the web where the node.innerHTML is read into a "hidden" iframe and then printed from there. I suspect that would work, but I was wondering if there was a more dojo centric approach to printing. Any thoughts?

  • Explicit casting doesn't work in default model binding

    - by Felix
    I am using ASP.NET MVC2 and Entity Framework. I am going to simplify the situation a little; hopefully it will make it clearer, not more confusing! I have a controller action to create address, and the country is a lookup table (in other words, there is a one-to-many relationship between Country and Address classes). Let's say for clarity that the field in the Address class is called Address.Land. And, for the purposes of the dropdown list, I am getting Country.CountryID and Country.Name. I am aware of Model vs. Input validation. So, if I call the dropdown field formLand - I can make it work. But if I call the field Land (that is, matching the variable in Address class) - I am getting the following error: "The parameter conversion from type 'System.String' to type 'App.Country' failed because no type converter can convert between these types." OK, this makes sense. A string (CountryID) comes from the form and the binder doesn't know how to convert it to Country type. So, I wrote the converter: namespace App { public partial class Country { public static explicit operator Country(string countryID) { AppEntities context = new AppEntities(); Country country = (Country) context.GetObjectByKey( new EntityKey("AppEntities.Countries", "CountryID", countryID)); return country; } } } FWIW, I tried both explicit and implicit. I tested it from the controller - Country c = (Country)"fr" - and it works fine. However, it never got invoked when the View is posted. I am getting the same "no type converter" error in the model. Any ideas how to hint to the model binder that there is a type converter? Thanks

  • Alfresco Community Edition Consultants

    - by Talkincat
    I am in the process of putting together an document management system based on Alfresco Community 3.2r2. Because Alfresco will not allow its partners to work with the Community edition, I have found it devilishly tricky to find consultants that specialize in Alfresco to help me with this project. Can anyone point me in the direction of someone that can help me get this system up an running? I will mostly need help with integrating Alfresco with Active Directory (LDAP passthrough, user/group sync and SSO) and performance tuning the system. Any help is greatly appreciated.

  • Apache Upgrade Version

    - by mcondiff
    I have a live server that I need to upgrade Apache from 2.2.10 to 2.2.15 on Windows Server 2003. I have just inherited this server and need the fastest way to upgrade to the latest stable version without much downtime and without messing up my configuration. My first thought is to copy the httpd.conf, uninstall the current Apache, install the latest stable Apache version and then replace the httpd.conf with the previous live version. Anyone see a problem or pitfall with that? How does a Server Pro do something like this. (I'm a programmer and am new to server systems administration).

  • Problems with SCP stalling during file copy over VPN

    - by MattC
    I have a series of files I need to copy via SCP over a VPN to a remote linux server each night. The files are not large, we're talking about tens of megabytes here, but the file copy almost always stalls after a few seconds. Running the SCP command with -vvv, I see the following over and over throughout the attempted copy process: debug2: channel 0: rcvd adjust 131072 debug2: channel 0: rcvd adjust 131072 debug2: channel 0: rcvd adjust 131072 Any thoughts? I see this question being asked in various places out there, but never any answers. Any help would be appreciated.

  • LDAP (slapd) creating users with access to specific trees

    - by Josh
    I am setting up a CentOS server with Virtualmin and Postfix, and I am trying to use LDAP to store unix users, groups, Postfix aliases and virtual domains. I am following the instructions from Webmin's site. I have created an LDAP domain and configured Postfix to fetch Aliases and Virtual Domains from LDAP, but in order to do so I had to configure postfix to authenticate with the master LDAP account, cn=Manager,dc=mydomain,dc=com. This seems like a terrible idea because that account has access to the Users and Groups, which postfix does not need access to. How can I create a new LDAP account for Postfix which only has access to the LDAP trees Postfix needs?

  • Windows XP Freezes

    - by Jim Fell
    Hello. I'm running a machine with Windows XP Professional 64-bit. Every so often, it will freeze for no apparent reason. That is, everything stops responding, except the mouse. I can move the mouse around, but I can't click on anything. Keyboard input is also not accepted/received when this problem occurs. The three-finger salute fails to bring up the Task Manager. Even pressing the power button on my computer fails to shut it down. The only way out of this that I have found is to hard-reboot the machine (i.e. pull power or hold power button in for 10 seconds). This problem was occurring on the system when it had all its updates and after a fresh install when not everthing was quite yet updated. I've run the Scandisk utility and the latest version Memtest86 that supports 64-bit architecture; neither found any errors. The last time this happened was on a fresh install of Windows. Only Nero Essentials, Avast antivirus (disabled), Firefox, and Spybot were installed. I was not running Nero, Firefox, or Spybot at the time, and Avast was disabled, so I'm pretty certain this is a Windows issue. Is anybody familiar with this problem or have any pointers? Thanks.

  • Printing without breaking accross pages.

    - by jedberg
    I have a page with a bunch of HTML tables that I need to print. Each table should fit on one page, but both Firefox and Safari want to break them over multiple pages and put more than one on a page. Is there any way to force it to not break the tables across pages? I can use any Mac program to print. Thanks.

  • HP Photosmart 7450 Prints Noise On Windows 7 Pro 64-bit

    - by David Mackintosh
    I have received a working (in its last location) HP Photosmart 7450 printer. I connected it up to my Windows 7 Pro 64-bit workstation, and the driver was (apparently) installed. The problem is that whenever I try to print from it -- test page, text from notepad, picture, whatever -- it spins through a half dozen sheets of paper, some of which have fractions of text on them, but most of which are either blank or have line noise printed on them. Noise similar to what was printed out on ye olde laserjet printers when the postscript interpreter failed. HP's web site only has a "use the included driver in Windows 7, be happy" instruction. The driver has been removed and added several times. The printer was previously attached to a XP Home computer and worked correctly without incident. Does anyone have any ideas for troubleshooting before I drop this printer in the river?

    Sound in Ubuntu, it has its own special joy. I would like my external microphone to work. Symptoms: I can play sound through the speakers I can play sound through the headsets. Plugging and and plugging headphone output correctly switches. I can record from the built-in microphone, using "Sound Recorder" and others. but: I cannot record from the external microphone. My Sound Preferences/Input panel has no option for an external microphone. If the answer is upgrade the ALSA drivers, please say exactly what to type. Thank you. ======== I'm using Ubuntu 9.10 Karmic Koala on a laptop (Gateway W3501), Sigmatel.

  • Deleting entire lines in a text file based on a partial string match with Windows PowerShell

    - by Charles
    So I have several large text files I need to sort through, and remove all occurrences of lines which contain a given keyword. So basically, if I have these lines: This is not a test This is a test Maybe a test Definitely not a test And I run the script with 'not', I need to entirely delete lines 1 and 4. I've been trying with: PS C:\Users\Admin (Get-Content "D:\Logs\co2.txt") | Foreach-Object {$_ -replace "3*Program*", ""} | Set-Content "D:\Logs\co2.txt" but it only replaces the 'Program' and not the entire line.

  • Generating moderately interesting images

    - by Williham Totland
    Abstract: Can you propose a mathematical-ish algorithm over a plane of pixels that will generate a moderately interesting image, preferably one that on the whole resembles something? The story thus far: Once upon a time I decided in an effort to reduce cycle waste on my (admittedly too) numerous computers, and set out to generate images in a moderately interesting fashion; using a PRNG and some clever math to create images that would, on the whole, resemble something. Or at least, that was the plan. As it turns out, clever math requires being a clever mathematician; this I am not. At some length I arrived at a method that preferred straight lines (as these are generally the components of which our world is made), perhaps too strongly. The result is mildly interesting; resembling, perhaps, city grids as such: Now for the question proper: Given the source code of this little program; can you improve upon it and propose a method that gives somewhat more interesting results? (e.g. not city grids, but perhaps faces, animals, geography, what have you) This is also meant as a sort of challenge; I suppose and as such I've set down some completely arbitrary and equally optional rules: The comments in the code says it all really. Suggestions and "solutions" should edit the algorithm itself, not the surrounding framework, except as for to fix errors that prevents the sample from compiling. The code should compile cleanly with a standard issue C compiler. (If the example provided doesn't, oops! Tell me, and I'll fix. :) The method should, though again, this is optional, not need to elicit help from your friendly neighborhood math library. Solutions should probably be deliverable by simply yanking out whatever is between the snip lines (the ones that say you should not edit above and below, respectively), with a statement to the effect of what you need to add to the preamble in particular. The code requires a C compiler and libpng to build; I'm not entirely confident that the MinGW compiler provides the necessities, but I would be surprised if it didn't. For Debian you'll want the libpng-dev package, and for Mac OS X you'll want the XCode tools.. The source code can be downloaded here. Warning: Massive code splurge incoming! // compile with gcc -o imggen -lpng imggen.c // optionally with -DITERATIONS=x, where x is an appropriate integer // If you're on a Mac or using MinGW, you may have to fiddle with the linker flags to find the library and includes. #include <stdio.h> #include <stdlib.h> #include <png.h> #ifdef ITERATIONS #define REPEAT #endif // ITERATIONS // YOU MAY CHANGE THE FOLLOWING DEFINES #define WIDTH 320 #define HEIGHT 240 // YOU MAY REPLACE THE FOLLOWING DEFINES AS APPROPRIATE #define INK 16384 void writePNG (png_bytepp imageBuffer, png_uint_32 width, png_uint_32 height, int iteration) { char *fname; asprintf(&fname, "out.%d.png", iteration); FILE *fp = fopen(fname, "wb"); if (!fp) return; png_structp png_ptr = png_create_write_struct(PNG_LIBPNG_VER_STRING, NULL, NULL, NULL); png_infop info_ptr = png_create_info_struct(png_ptr); png_init_io(png_ptr, fp); png_set_filter(png_ptr, PNG_FILTER_TYPE_DEFAULT, PNG_FILTER_NONE); png_set_compression_level(png_ptr, Z_BEST_COMPRESSION); png_set_IHDR(png_ptr, info_ptr, width, height, 8, PNG_COLOR_TYPE_GRAY, PNG_INTERLACE_NONE, PNG_COMPRESSION_TYPE_DEFAULT, PNG_FILTER_TYPE_DEFAULT); png_set_rows(png_ptr, info_ptr, imageBuffer); png_set_invert_mono(png_ptr); /// YOU MAY COMMENT OUT THIS LINE png_write_png(png_ptr, info_ptr, PNG_TRANSFORM_IDENTITY, NULL); png_destroy_write_struct(&png_ptr, &info_ptr); fclose(fp); free(fname); } int main (int argc, const char * argv[]) { png_uint_32 height = HEIGHT, width = WIDTH; int iteration = 1; #ifdef REPEAT for (iteration = 1; iteration <= ITERATIONS; iteration++) { #endif // REPEAT png_bytepp imageBuffer = malloc(sizeof(png_bytep) * height); for (png_uint_32 i = 0; i < height; i++) { imageBuffer[i] = malloc(sizeof(png_byte) * width); for (png_uint_32 j = 0; j < width; j++) { imageBuffer[i][j] = 0; } } /// CUT ACROSS THE DASHED LINES /// ------------------------------------------- /// NO EDITING ABOVE THIS LINE; EXCEPT AS NOTED int ink = INK; int x = rand() % width, y = rand() % height; int xdir = (rand() % 2)?1:-1; int ydir = (rand() % 2)?1:-1; while (ink) { imageBuffer[y][x] = 255; --ink; xdir += (rand() % 2)?(1):(-1); ydir += (rand() % 2)?(1):(-1); if (ydir > 0) { ++y; } else if (ydir < 0) { --y; } if (xdir > 0) { ++x; } else if (xdir < 0) { --x; } if (x == -1 || y == -1 || x == width || y == height || x == y && x == 0) { x = rand() % width; y = rand() % height; xdir = (rand() % 2)?1:-1; ydir = (rand() % 2)?1:-1; } } /// NO EDITING BELOW THIS LINE /// ------------------------------------------- writePNG(imageBuffer, width, height, iteration); for (png_uint_32 i = 0; i < height; i++) { free(imageBuffer[i]); } free(imageBuffer); #ifdef REPEAT } #endif // REPEAT return 0; } Note: While this question doesn't strictly speaking seem "answerable" as such; I still believe that it can give rise to some manner of "right" answer. Maybe. Happy hunting.
