  • Getting a NullReferenceException Error when invoking a Select File Dialog Box

    - by codingguy3000
    Hey everyone This is a real newbie question. I have simple app that selects a picture and display's that picture in a PictureBox. I decided to mess with the Opacity Attribute so I added a timer and created this cool effect where the Main Form's Opacity is increased by 20% every 400 miliseconds. The problem is that now when I click the button that invokes the Select File Dialog Box I'm getting a NullReferenceException error. private void tmrClock_Tick(object sender, EventArgs e) { if (ViewerForm.ActiveForm.Opacity != 1) { ActiveForm.Opacity = ActiveForm.Opacity + .20; } } The error message is pointing to the if statement. What am I doing wrong? Thanks

  • Connect Android application to remote data

    - by tadywankenobi
    Sheesh talk about limited information! I'm trying to get my Android application to connect to an online database to access information. There's quite a bit of info including geotags and these are going to be mapped on my app. The developer site has the very informative piece of information: You can use the network (when it's available) to store and retrieve data on your own web-based services. To do network operations, use classes in the following packages: java.net.* android.net.* Like I said in my previous question, I'm still very much an android newbie, and trying to remember my java oop from college is slow. Does anyone have an example of how this might work, or how I could implement it? I wouldn't mind even connecting to a local xml file, if I could find a good example of how to do that!? Am I just looking in all the wrong places?! Help. Please! T

  • Unable to locate using find element by link

    - by First Rock
    Newbie in testing. I generated a test case using Selenium, and then exported it as a Python script. Now, when I try to run that in terminal, I get following error: raise exception_class(message, screen, stacktrace) NoSuchElementException: Message: u'Unable to locate element: {"method":"link text","selector":"delete"}' I am using the command generated by Selenium i.e driver.find_element_by_link_text("delete").click() The reason for the error I believe is that the link "delete" in my web page is seen only when I click on a particular line to be deleted. So I guess it is being unable to locate the link. Please suggest what alternative measure could I use to locate and click on the "delete" link. Thanks in Advance:)

  • jquery toggle+paginate+multiple instances

    - by mark
    Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

  • Creation of database in Oracle

    - by macha
    Hello, I am a newbie to Oracle, and I have used MySQL for most of the time. So now for testing scripts, I was just planning to create a database, but from the resources I have found on google, it doesn't look as simple it is maybe in mysql or in sqlserver. I just need to create a database, say "CREATE DATABASE TESTDB";. That is it, but of the resources I have found, it seems I need to create an instance identifier, decide an authentication method, create an initialization file etc. Do I really have to do all this or am I using the wrong resources. I just need to create a database and add a few tables into it, just to check my connection string etc. I need to check if I am able to connect to my web server.

  • Maven overlay with war not generated by maven

    - by dnc253
    I'm pretty new to Maven, so I apologize if this is a newbie question. We are trying to integrate a 3rd-party app into ours. This 3rd-party functionality is delivered to us as a war file. As part of this integration, I want to add some extra jars and and a properties file. Googling around, I discovered overlays. However, in all the examples I've seen, it looks the the wars that are being overlayed, were themselves generated by Maven, and thus Maven can figure out dependencies, conflicts, etc. between the two. I'm just wondering if there's a way for me to overlay this 3rd-party war with this extra stuff I want. If so, what would that look like in the pom.xml?

  • Conditionally setting the font color of an item in a drop down box in JSF

    - by Greg
    I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

    - by Eliseo Soto
    Hi, I started a new project and created a local git repo with "git init" and now I have a few branches and everything works great. However since my webhosting company offers git hosting (if you're curious https://support.eapps.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=203) I'd like to push my entire repo to their servers to have a backup in the cloud in case something bad happens to my local repo. How can I make the remote repo the "origin" since the repo was started locally? Hope my question makes sense. Thanks, a Git newbie.
