I want to use custom like button instead of Facebook's Like button in my android application.Is it possible to use custom Like buttons? How to implement this?I searched in StackOverFlow, but could not find any helpful information.

WPF Custom TextBox with Decimal Formatting

问题 I am new to WPF. I have a requirement that I need to develop a custom textbox control which should support the functionality like: Should accept only decimal values.

Custom FXML component (w/ controller) doesn't appear in SceneBuilder's “Import jar” dialog

阅读更多关于 Custom FXML component (w/ controller) doesn't appear in SceneBuilder's “Import jar” dialog

I am following this in creating a custom component and importing it. However, when it gets to the Import Dialog after clicking the jar file, it does not appear. When I comment out the code the tutorial used for the constructor, it appears again. However, none of the subcomponents I used to make the custom one appear. Why and how do I fix it? Also, I am using a VBox instead of an AnchorPane (as seen in the tutorial) for my own thing. Code of constructor as seen in tutorial: public CommodityImageLabel() { FXMLLoader fxmlLoader = new FXMLLoader( getClass().getResource("/fxml/CommodityImageLabel

问题 I've created a custom combobox with DrawMode = OwnerDrawVariable. Everything is fine, except it doesn't use visual styles anymore in DropDownList mode, i.e. it looks like old combobox. How can I make it drawn using visual styles? I checked VisualStyleElement class but haven't found there anything that could help me. Does it mean that OwnerDraw combobox can't be drawn with visual styles??? 回答1: I don't see anything in the 7.0 version of the SDK that allows drawing that style. The

问题 I'm trying to make a game and want the user to change their input keys, e.g. they press the A key and that changes the MoveUp variable to the A key so that when they press A in the game they move upwards.

HTML 'name' attribute generated for ASP.net child controls, instead of the unique 'ID' attribute

阅读更多关于 HTML 'name' attribute generated for ASP.net child controls, instead of the unique 'ID' attribute

The generated HTML code for my custom ASP.net server control generates the name attribute for child controls, instead of the id attribute. Something like this : <span id="GridView2_ctl02_editdis"> <input type="text" name="GridView2$ctl02$editdis$ctl00"/> </span> The ID for the custom control itself is apparently proper. What is even stranger for me, is that the ID does get generated sometimes (I do not know under what conditions). But a FindControl() with that ID returns null on the server side. FindControl() with the value of the name attribute works just fine. Something like this : <span
