  • How to set source path of image within html pages to show in webbrowser control

    - by Royson
    Hi in my application there is web browser control to show some static html pages. The pages are displayed properly. but images are not displayed.. I tried with changing src-path but no success. my htmlpages folder is located at bin folder. And i am assigning it as. FileStream source = new FileStream(@"..\HtmlPages\supportHtml.html", FileMode.Open, FileAccess.Read); if i open html files in browser, the images are displayed properly.. So, What is the correct path for images..?? If i set full path to src attribute of <img> tag..it works. but i think its not a proper way. :( EDIT: If i assign d:\myapp\bin\HtmlPages\support.gif then image is displayed. And if i assign "..\HtmlPages\support.gif" or "support.gif" image is not shown.

  • UITextView on iPad INCREDIBLY Slow

    - by Sj
    I have an NSMutableArray of custom views (that are pretty much 1 UITextView and 1 UILabel with a custom back ground image), these are created as they are need (I start with 2 (though the first one is only 2 UITextFields and the other is normal) of these). Now my issue here seems to be this: as soon as I try to edit any UITextView past the one in the 2nd view, it starts to run incredibly slow, not the app, just the textview. For example, as I type, the little blinky guy lags behind the text and when I click to copy/paste/cut/etc you can see the little balloon fly in from the upper left corner every time. I have run the static analyzer for leaks and come up with nothing and run it alongside some other the testing software in XCode and it does not appear to have any reason for this. Any help would be greatly appreciated.

  • Recommendations for 'C' Project architecture guidelines?

    - by SiegeX
    Now that I got my head wrapped around the 'C' language to a point where I feel proficient enough to write clean code, I'd like to focus my attention on project architecture guidelines. I'm looking for a good resource that coves the following topics: How to create an interface that promotes code maintainability and is extensible for future upgrades. Library creation guidelines. Example, when should I consider using static vs dynamic libraries. How to properly design an ABI to cope with either one. Header files: what to partition out and when. Examples on when to use 1:1 vs 1:many .h to .c Anything you feel I missed but is important when attempting to architect a new C project. Ideally, I'd like to see some example projects ranging from small to large and see how the architecture changes depending on project size, function or customer. What resource(s) would you recommend for such topics?

  • Browser caching issue on a https site pressing f5

    - by sushil bharwani
    i am working on a website where i have content entry form. This form contains a tiny mce control. The control is composed of some 40-50 files. The testing reported that the entry form loads slow and evertime shows up 50 files loading to completely load the page. Is there a way i can decrease this time. I have taken help of browser caching by setting the expires header of static content to very far date. When i access the form through its link second or later times it loads fast without saying 40 files remaining. but when i do f5 it reloads the entire page. I m confused as to how is f5 different from clicking on the link. Just to add my url is https.Any suggestion to increase the performance of this form will be great.

  • How can I handle template dependencies in Template Toolkit?

    - by Smack my batch up
    My static web pages are built from a huge bunch of templates which are inter-included using Template Toolkit's "import" and "include", so page.html looks like this: [% INCLUDE top %] [% IMPORT middle %] Then top might have even more files included. I have very many of these files, and they have to be run through to create the web pages in various languages (English, French, etc., not computer languages). This is a very complicated process and when one file is updated I would like to be able to automatically remake only the necessary files, using a makefile or something similar. Are there any tools like makedepend for C files which can parse template toolkit templates and create a dependency list for use in a makefile? Or are there better ways to automate this process?

  • Call Babel .Net Obfuscator from C# Code

    - by aron
    Hello, I have a C# WinForms app that I use to create software patches for my app. In noticed that Babel .Net includes Babel.Build.dll and Babel.Code.dll Is there a way, in my C# code, I can call Babel .Net something like: ExecuteCommand(C:\Program Files\Babel\babel.exe "C:\Patch\v6\Demo\Bin\Lib.dll" --rules "C:\Patch\babelRules.xml", 600) Here's a common script to execute a CMD prompt in C#. However if I just include the Babel.Build.dll in my winform I may be able to do it seamlessly. public static int ExecuteCommand(string Command, int Timeout) { int ExitCode; ProcessStartInfo ProcessInfo; Process Process; ProcessInfo = new ProcessStartInfo("cmd.exe", "/C " + Command); ProcessInfo.CreateNoWindow = true; ProcessInfo.UseShellExecute = false; Process = Process.Start(ProcessInfo); Process.WaitForExit(Timeout); ExitCode = Process.ExitCode; Process.Close(); return ExitCode; }

  • Is there a nice XSL stylesheet for client-side DocBook rendering?

    - by Steven Huwig
    I want the DocBook documents in my SVN repository to look nice if someone looks at them in a web browser. I've started to write a CSS stylesheet, but I think that it will have significant limitations -- particularly ones regarding hyperlinks. There is a large body of DocBook XSL stylesheets at the DocBook site , but they don't seem to be appropriate for browser rendering. I don't want to generate static documents and put them into SVN. I want them to be basically readable for other developers without much hassle. I could write my own browser-appropriate XSL stylesheet to convert DocBook to HTML, but it seems like someone else must have already done this. I just don't know where to find it.

  • ag_e_parser_bad_property_value Silverlight Binding Page Title

    - by zXynK
    XAML: <navigation:Page ... Title="{Binding Name}"> C# public TablePage() { this.DataContext = new Table() { Name = "Finding Table" }; InitializeComponent(); } Getting a ag_e_parser_bad_property_value error in InitializeComponent at the point where the title binding is happening. I've tried adding static text which works fine. If I use binding anywhere else eg: <TextBlock Text="{Binding Name}"/> This doesn't work either. I'm guessing it's complaining because the DataContext object isn't set but if I put in a break point before the InitializeComponent I can confirm it is populated and the Name property is set. Any ideas?

  • Need to get back form controls' information externally

    - by Tom
    Are there any tutorials or guides out there that anyone knows of that will show me how to read forms from an external program and get back information about the controls on the form? Currently, I can get the handle to the form, and I can get the class name, but I need to get more information such as a persistent name and contained data. Thanks. Edit: I now have a way to read the contained data (with the WM_GETTEXT message), however, I still need a persistent name/ID that I can be sure will not change from instance to instance. One way I can think of for doing this is to take the handle, find the position of the control on the window, and then get the handle from the position from then on. Another way is to determine a static ID for the control and then use that to get the handle from then on. The new scope of my problem is how to implement either of these. Any Ideas?

  • General Policies and Procedures for Maintaining the Value of Data Assets

    Here is a general list for policies and procedures regarding maintaining the value of data assets. Data Backup Policies and Procedures Backups are very important when dealing with data because there is always the chance of losing data due to faulty hardware or a user activity. So the need for a strategic backup system should be mandatory for all companies. This being said, in the real world some companies that I have worked for do not really have a good data backup plan. Typically when companies tend to take this kind of approach in data backups usually the data is not really recoverable.  Unfortunately when companies do not regularly test their backup plans they get a false sense of security because they think that they are covered. However, I can tell you from personal and professional experience that a backup plan/system is never fully implemented until it is regularly tested prior to the time when it actually needs to be used. Disaster Recovery Plan Expanding on Backup Policies and Procedures, a company needs to also have a disaster recovery plan in order to protect its data in case of a catastrophic disaster.  Disaster recovery plans typically encompass how to restore all of a company’s data and infrastructure back to a restored operational status.  Most Disaster recovery plans also include time estimates on how long each step of the disaster recovery plan should take to be executed.  It is important to note that disaster recovery plans are never fully implemented until they have been tested just like backup plans. Disaster recovery plans should be tested regularly so that the business can be confident in not losing any or minimal data due to a catastrophic disaster. Firewall Policies and Content Filters One way companies can protect their data is by using a firewall to separate their internal network from the outside. Firewalls allow for enabling or disabling network access as data passes through it by applying various defined restrictions. Furthermore firewalls can also be used to prevent access from the internal network to the outside by these same factors. Common Firewall Restrictions Destination/Sender IP Address Destination/Sender Host Names Domain Names Network Ports Companies can also desire to restrict what their network user’s view on the internet through things like content filters. Content filters allow a company to track what webpages a person has accessed and can also restrict user’s access based on established rules set up in the content filter. This device and/or software can block access to domains or specific URLs based on a few factors. Common Content Filter Criteria Known malicious sites Specific Page Content Page Content Theme  Anti-Virus/Mal-ware Polices Fortunately, most companies utilize antivirus programs on all computers and servers for good reason, virus have been known to do the following: Corrupt/Invalidate Data, Destroy Data, and Steal Data. Anti-Virus applications are a great way to prevent any malicious application from being able to gain access to a company’s data.  However, anti-virus programs must be constantly updated because new viruses are always being created, and the anti-virus vendors need to distribute updates to their applications so that they can catch and remove them. Data Validation Policies and Procedures Data validation is very important to ensure that only accurate information is stored. The existence of invalid data can cause major problems when businesses attempt to use data for knowledge based decisions and for performance reporting. Data Scrubbing Policies and Procedures Data scrubbing is valuable to companies in one of two ways. The first can be used to clean data prior to being analyzed for report generation. The second is that it allows companies to remove things like personally Identifiable information from its data prior to transmit it between multiple environments or if the information is sent to an external location. An example of this can be seen with medical records in regards to HIPPA laws that prohibit the storage of specific personal and medical information. Additionally, I have professionally run in to a scenario where the Canadian government does not allow any Canadian’s personal information to be stored on a server not located in Canada. Encryption Practices The use of encryption is very valuable when a company needs to any personal information. This allows users with the appropriated access levels to view or confirm the existence or accuracy of data within a system by either decrypting the information or encrypting a piece of data and comparing it to the stored version.  Additionally, if for some unforeseen reason the data got in to the wrong hands then they would have to first decrypt the data before they could even be able to read it. Encryption just adds and additional layer of protection around data itself. Standard Normalization Practices The use of standard data normalization practices is very important when dealing with data because it can prevent allot of potential issues by eliminating the potential for unnecessary data duplication. Issues caused by data duplication include excess use of data storage, increased chance for invalidated data, and over use of data processing. Network and Database Security/Access Policies Every company has some form of network/data access policy even if they have none. These policies help secure data from being seen by inappropriate users along with preventing the data from being updated or deleted by users. In addition, without a good security policy there is a large potential for data to be corrupted by unassuming users or even stolen. Data Storage Policies Data storage polices are very important depending on how they are implemented especially when a company is trying to utilize them in conjunction with other policies like Data Backups. I have worked at companies where all network user folders are constantly backed up, and if a user wanted to ensure the existence of a piece of data in the form of a file then they had to store that file in their network folder. Conversely, I have also worked in places where when a user logs on or off of the network there entire user profile is backed up. Training Policies One of the biggest ways to prevent data loss and ensure that data will remain a company asset is through training. The practice of properly train employees on how to work with in systems that access data is crucial when trying to ensure a company’s data will remain an asset. Users need to be trained on how to manipulate a company’s data in order to perform their tasks to reduce the chances of invalidating data.

  • PHP anonymous functions scope question

    - by Dan
    Hi, I'm trying to sort an array of objects by a common property, however I cannot get my $property parameter to register in the inner function (I can use it in the outer one OK). The way I read the documentation, it sounded like the parameter would be available, have I misunderstood something? Here is what I have: public static function sortObjectsByProperty($objects, $property) { function compare_object($a, $b) { $a = $a->$property; $b = $b->$property; if ($a->$property == $b->$property) { return 0; } return ($a->$property > $b->$property) ? +1 : -1; } usort($objects, 'compare_object'); return $objects; } Any advice appreciated. Thanks.

  • WPF DependencyProperty event before content changed

    - by morsanu
    First I will explain the context of the problem, because you might be able to point me in a better direction. I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type. I need to save the value of the property before it is changed, and for this I added the CoerceValueCallback. public static readonly DependencyProperty MyBackgroundProperty = DependencyProperty.Register("MyBackground", typeof(MyCustomizableBackground), typeof(MyComponent), new UIPropertyMetadata(default(MyCustomizableBackground), null, new CoerceValueCallback(OnPropertyChanged))); In OnPropertyChanged I save the value before it's changed. MyCustomizableBackground is the DependencyObject that has also some dependency properties. The problem is that in this case, where I have a custom object as a property, the OnPropertyChanged method isn't triggered, but when I have a common type, it is triggered.
