    - by Sev
    Besides Arduino, what other ways are there to learn hardware programming in a hands-on way? Are there any nifty kits available, either a pre-assembled robot, that you can program to move a certain way, or do certain things, or anything similar to that?

  • Paypal Mass pay fails when large transactions are made

    - by Sid
    I am using the paypal mass pay feature but i am unable to make payments greater than $20. When I attempt to make large transactions (say for $120) i get the error that says the account has insufficient funds. My account has more than the requisite amount to make the payment. I am trying to find a solution as there is no documentation that says anything about an a limit for each payment in the mass pay api. I would appreciate any help on this.

  • MySql TABLE data type

    - by Neil Aitken
    MS SQL Server has a TABLE data type which can be used in stored procedures, Does anybody know if MySQL has an equivalent data type? I've had a look over the docs but can't seem to find anything, so I presume it doesn't exist, but perhaps somebody has created a workaround

  • What method can I override in GridViewHeaderRowPresenter to prevent it from drawing some columns?

    - by Carlo
    The thing is that I created a custom column that inherits from GridViewColumn, and I added a Visibility dependency property to it. Now I want to create a custom GridViewHeaderRowPresenter, that does not draw the columns when their visibility is hidden or collapsed, but other than the OnRender() method, I can't think of anything else. Thanks. Btw, the reason I'm doing this is because removing or adding columns doesn't work like we would expect it (some specs for our app) and I believe what I'm trying to do here would work if pulled out correctly.

  • how to tell which object called a delegate method (objective c)

    - by user353877
    Let's say you have two objects (UITextviews) in your class. When the text view changes, you have a delegate method that catches the change.. but how can you tell programatically WHICH object was changed and called the delegate ?? I have to be missing something, because this should be trivial, but I couldnt find anything. Note: In this case, its not possible to just break up the class to only have one object (there by bypassing ambiguity).. I looked for things like assigned variable names for nsobjects, nothing there

  • Android Assets No Value Read?

    - by BahaiResearch.com
    AssetManager assets = myContext.getAssets(); String[] files = assets.list("MyFolder"); InputStream myInput = assets.open("MyFolder/" + files[0]); int i = myInput.read(); in this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable?

  • How to reorder type members with Resharper?

    - by AngryHacker
    Typical scenario: a class that a lot of people have worked on. I'd like to sort methods, properties, etc... in alphabetical order. I'd like to be able to do this within the region or globally in the class. I see the feature in Resharper to do it, but it does not seem to do anything.

  • What is the "proper" method for determining if a swf is running within an AIR application?

    - by Michael Prescott
    I've got a Flex Web project and a Flex AIR project that use a common code-base. The common code defines several run-time loaded Flex Modules. I want the Flex Modules to behave differently depending on whether the running base application is WEB or AIR. What is the proper method for determining from the module code whether the module is running in a WEB or AIR application? (I found that Security.sandboxType.toString() returns "application", but I haven't found anything better in the documentation, yet.)
