  • Best Practices & Considerations when writing HTML Emails

    - by Jonathan Sampson
    I've been developing websites for over a decade now, but quickly found that many of my habits in developing for the web are useless when developing for email clients. This has caused me an enormous amount of frustration, so I thought I would ask a question that would hopefully surface the best practices and necessary considerations for others like myself who may find themselves designing for gmail, outlook, etc. from time to time. Example: <style>...</style> vs inline CSS. In short: what transfers over from the web-world to the email-world, and what doesn't.

  • Image container instead of event object in image load event handler

    - by avok00
    I stumbled upon a very strange thing. In FF 3.6 (not tested others yet) I add onload handler to an image like this: imgRef.addEventListener("load", activateLink, false); When load event fires, in activateLink(evt) the evt paramater is not an event, but the "a" tag that contains the image. Why is this? function activateLink(evt) { // evt turns out to be a refference to <a> tag (HTMLAnchorElement) that contains the image. // Actually two of them. Both dynamically added with addElement. } I remembered another fact that may be relevant. I have multiple images with the same src that all have registered this same event handler activateLink. Could this be the problem?

  • How do I deploy a utility with ocx dependency to a test machine without registering the ocx?

    - by Brandon
    I have a test utility that depends upon an ocx file that is installed/registered on my development machine. We'd like to run this tool on a test machine without polluting the machine with any unnecessary files. Nothing should be installed except the target machine software. Running the tool on a network drive or from a stand-alone directory copied to the test machine would be ideal. But, registering the ocx on the test machine is out of the question. Placing the ocx file in the same directory as the exe doesn't work. No matter what it still gives me this error--"The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem." What else can I try?

  • What is the optimal number of threads for performing IO operations in java?

    - by marc
    In Goetz's "Java Concurrency in Practice", in a footnote on page 101, he writes "For computational problems like this that do not I/O and access no shared data, Ncpu or Ncpu+1 threads yield optimal throughput; more threads do not help, and may in fact degrade performance..." My question is, when performing I/O operations such as file writing, file reading, file deleting, etc, are there guidelines for the number of threads to use to achieve maximum performance? I understand this will be just a guide number, since disk speeds and a host of other factors play into this. Still, I'm wondering: can 20 threads write 1000 separate files to disk faster than 4 threads can on a 4-cpu machine?

  • Build Event Macros for Other Projects in the Solution

    - by Adam Driscoll
    Is it possible to reference other projects' properties via a macro within a build event? For example: "Tool1" outputs to directory ..\..\bin\Release "Component1" uses "Tool1" in its post-buildevent To get to "Tool1", "Component1"'s project must do something like $(SolutionDir)bin\Release This requires that Tool1 always output to ..\..\bin\Release. If this is changed this breaks the other project. I know there is no indication to this within the macro list but is there a way to reference another project? Maybe like $(OtherProject.TargetDir)... I know WIX has a similar syntax [$(var.OtherProject.TargetDir)] but I think that may be a different mechanism.

  • Creating a function that will handle objects with common properties

    - by geocine
    Take this as an example I have trimmed this example for readability and you may not find the use of this concept here. class Teacher() { public Name {get; set;} public Salt {get; set;} public Department{get; set;} } class Student() { public Name {get; set;} public Salt {get; set;} public Section{get; set;} } public string GetEncryptedName(object Person) { //return encrypted name based on Name and Salt property return encrypt(object.Salt,object.Name) } callig the function GetEncryptedName(Teacher) GetEncryptedName(Student) How do you implement this kind of stuff?

  • How to determine item at a index in pattern

    - by el.gringogrande
    I have the following elements in a list/array a1,a2,a3 and these elements are used to build another list in a predictable pattern example a1,a1,a2,a2,a3,a3,a1,a1,a2,a2,a3,a3... The pattern may change but I will always know how many times each element repeats and all elements repeats the same number of times. And the elements always show up in the same order. so another pattern might be a1,a1,a1,a2,a2,a2,a3,a3,a3,a1,a1,a1,a2,a2,a2,a3,a3,a3... or a1,a2,a3,a1,a2,a3 it will never be a2,a2,a1,a1,a3,a3... or a1,a2,a3,a2,a3,a1 etc How I determine what element is at any index in the list?

  • WPF EDitable ComboBox

    - by Amittai Shapira
    Hi! I want to create editable combo box with the following properties: 1. Bind the text property to my data model. 2. The data model may override the changes in the GUI, even in Selection changed. E.g. I can choose from 1, 2, 3 I choose 2, but some component down under changes it to 3. 3. Update the data model on the following events: 1. Selection Changed 2. Lose focus 3. Enter pressed (should behave the same as lost focus). I've been able to create such control, but it's pretty ugly (using many hacks) and I hoped there's a simpler way… Thanks in advance

  • WSAT Security tab error for Custom Role provider

    - by shesb
    I have created custome Membership Role and Profile provider using INGRES db. Now I can see my IngresMembership and IngresRole provider in the Provider tab(Select a different provider for each feature (advanced) ) of WSAT but when I clik on security tab I get this error: "There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: Object reference not set to an instance of an object." What am I missing? Do I need to add code for all override methods for Role provider? I have just written code for the Initialize and GetRolesForUser functions. Thanks

  • Java, how to trace functions called

    - by user435657
    Hi all, I want to trace the beginning [& ending] of functions called in Java, like the following code: public void foo() { System.out.println("begin of foo()"); ... System.out.println("e-n-d of foo()"); } But maintaining of the dump code System.out.println is something tedious and error-prone, for there may be tens of thounds of function in an class. Any good idea can ease this work? I don't want dump statements all over the file. Implementation of both or one of the beginning & ending traces is perferd. But, if impossible, recordings of that the function has been called is also helpful. I mean not care the exact beginnig and ending, just tell that the function has been called.

  • My app crashes on Iphone SDK 3.2

    - by Mladen
    Hi Guys, My app worked ok on iPhone SDK 3.1. However, when I try to run it in 3.2 simulator, I get the following error and it crashes: bool _WebTryThreadLock(bool), 0x5148280: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now... Program received signal: “EXC_BAD_ACCESS”. When I debug it, it leads me to this peace of code: - (void)LoginViewToCheckView:(id)sender { CheckViewController *tempTestController = [[CheckViewController alloc] initWithStyle:UITableViewStyleGrouped]; [tempTestController setDelegate:self]; [self setCheckViewController: tempTestController]; [tempTestController release]; [navigationController pushViewController:checkViewController animated:YES];} Other thing worth mentioning is maybe that I am calling this function from a separate thread. Any ideas what could be wrong?

  • Is there such a thing as a dektop application event aggregator, similar to that used in Prism?

    - by brownj
    The event aggregator in Prism is great, and allows loosely coupled communication between modules within a composite application. Does such a thing exist that allows the same thing to happen between standalone applications running on a user's desktop? I could imagine developing a solution that uses WCF with TCP binding and running inside Windows Process Activation Service. Client applications could subscribe or publish events to this service as required and it would ensure all other listeners get notified of events as appropriate. Using TCP would enable event messages to be pushed out to clients without the need for polling, ensuring messages are delivered very quickly. I can't help but think though that such a thing would already exist... Is anyone aware of something like this, or have any advice on how it may be best implemented?

  • Exposing an ISO C++ class to C#

    - by Stick it to THE MAN
    I need to expose some C++ classes to C# (I am building on Linux, using mono, so COM is not an option) The evidence I have gathered so far suggests that the best way to approach this is: Write a wrapper C++.Net class around the ISO C++ class Consume the C++.Net classes from C# I have the following questions: First, is this the "best" way of achieving the goal of exposing ISO C++ classes to C# ? So far though, I have not seen any examples that actually show how to do this - can anyone suggest some links, or a code snippet to show how this is done for a dummy class? How may I send asynchronous message notifications from the C++ code to the C# code ?. Ideally, I would like to cause the C# class to raise an event, with the received data as an argument

  • iPhone SDK: How to store the time each word was typed?

    - by Harkonian
    My problem is twofold: 1) I'm trying to determine an eloquent way to allow the user to type into a UITextView and store the time each word was typed into an array. The time will be a float which starts at 0 when the user begins to type. 2) Conversely, I'd like the user to be able to tap on a word in the UITextView and display the time that word was typed (displaying in an NSLog() is fine). Considerations that may throw a wrench into a possible approach -- what if the user goes back to the top of the text and starts typing or to the middle of the text? Even a suggested approach without code would be appreciated, because right now I'm drawing a blank.

  • Reading and writing dates to the registry for trial version purposes.

    - by LeeW
    Hi all, Here's what I want to do, I want to store the date the first time the program is installed and also store a date when was the program was last run. I want the code to check to see if it was more than 30 days since the installation so I can turn off features. I also want to check if the system date is less than the last opened date and if so write the installed date to 1/1/1901 to prevent the program from running. Keeping in mind that this is not a consumer program but a business program I don't expect hackers to crack it, they may do but that is fine I simply want to give potential customers a reason to consider purchasing the program and the end of the trial will prompt this. 1: Does this sound reasonable? 2: How should I hide the fact this is a date so it's not easily changed? Many thanks Lee

  • installing NUMPY for Mac OSX 10.7. (Lion) for use with Python

    - by user1744871
    I Need to use nltk and numpy with Python. I am a newbie to Python and initially used the python 2.7.3 that came with my mac (currently running OSX 10.7.5). I learned that the apple version of python may not be robust so I downloaded the standard version from python.org. I have downloaded the nltk program for Mac OSX 10.7. This seemed to install fine. I am trying to download and install numpy using the instructions from the scipy website. http://www.scipy.org/Installing_SciPy/Mac_OS_X. I cloned numpy from github but when I tried to build it using the following command $ python setup.py build I received the following error MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory I also tried to build it using the scons command $ python setupscons.py scons --jobs=2 and received the following error /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setupscons.py': [Errno 2] No such file or directory Can anyone think of a possible workaround?

  • IE 8 prompts user on "slow" jQuery script

    - by Jason
    I have a form with over 100 list items that I must reorder on submit. The following code works to reorder my list without any apparent problems in Firefox; however, IE prompts with the message "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?" If the user clicks 'No', the script will work as expected. var listitems = $(form).find('li').get(); listitems.sort(function(a, b) { var compA = $(a).attr('id'); var compB = $(b).attr('id'); return (compA - compB); }); Any ideas on how to make this more efficient?

  • optimized grid for rectangular items

    - by peterchen
    I have N rectangular items with an aspect ratio Aitem (X:Y). I have a rectangular display area with an aspect ratio Aview The items should be arranged in a table-like layout (i.e. r rows, c columns). what is the ideal grid rows x columns, so that individual items are largest? (rows * colums = N, of course - i.e. there may be "unused" grid places). A simple algorithm could iterate over rows = 1..N, calculate the required number of columns, and keep the row/column pair with the largest items. I wonder if there's a non-iterative algorithm, though (e.g. for Aitem = Aview = 1, rows / cols can be approximated by sqrt(N)).

  • looking for a good vc++ profiler, already checked previous posts

    - by coreSOLO
    I'm looking for a good profiler for vs2008 professional edition, free or reasonably priced. I've already checked previous posts and tried about 8 profilers, but most of them are too basic or too detailed. Kindly suggest something, my requirements are as follows: It can be compiled, so that its well integrated with my application. I'm not shying away from instrumenting my methods. The output should be simple, i only need call count and time taken by methods and nothing else. I am mostly concerned about things INSIDE a method, you may call it line by line profiling. I want to select a method and know which line (expression / method call) is eating most of the time.

  • How to design WCF Contracts?

    - by Amitabh
    We are designing a WCF layer which can be invoked either by a Asp.Net or a WinForm application. Our Application contains too many Entities. If we design WCF Contract around these entities then we get too many Contracts e.g IPartyService, IUserService, IPaymentService etc. So, I may end up with 30-40 Contracts? Is it a good idea or should we go for one huge contracts with around 100 operations? What are the pros and cons of each approach or is there a better way.

  • Is the .Net HashSet uniqueness calculation completely based on Hash Codes?

    - by RobV
    I was wondering whether the .Net HashSet<T> is based completely on hash codes or whether it uses equality as well? I have a particular class that I may potentially instantiate millions of instances of and there is a reasonable chance that some hash codes will collide at that point. I'm considering using HashSet's to store some instances of this class and am wondering if it's actually worth doing - if the uniqueness of an element is only determined on its hash code then that's of no use to me for real applications MSDN documentation seems to be rather vague on this topic - any enlightenment would be appreciated

  • QWebPage. How to handle failed request.

    - by user453482
    I want to handle failed requests (for example, with http 404 error code in reply), display my own "notfound.html" page in QWebView. But there is no simple way to handle replies with QWebView/QWebPage classes. As I see in Arora browser, for such requests uses next mechanism: QWebPage::setForwardUnsupportedContent(true), QWebPage::unsupportedContent signal and appropriate slot where you can handle qnetworkreply manually. But I cannot understand how it works, because unsupportedContent throws only when QWebPage cannot handle request scheme (like abrakadra://, ftp://, etc) or if reply consists of special header Content-Disposition: attachment. May be anybody know something about this ?
