• Force ClickOnce - application to be started offline?

  - by stormianrootsolver

  I have a click once application here that needs to be started offline exclusively sometimes. Reason is that it needs to be started VERY early during boot, at a point when there is no network connection yet, also it must not wait for any network connectivity. I know, this requirement seems strange, but it has legacy reasons. What do you think?

• How to convert the amount of indentation in a source code file?

  - by toby

  I find that I now often work with code bases that have different amounts of indentation. Some use 2 spaces, some use 4 space, some even use tabs! Once in a while, I have to share code between these codebases, or, sometimes I use an incorrect amount of indentation by mistake. Is there a tool or a text editor feature that will convert between different amounts of indentation?

• How do I create a "global variable" in Java such that all classes can access it?

  - by Chrystle Soh

  here's my problem: I have multiple classes that are part of the same package and they need access to a certain file path String filePath = "D:/Users/Mine/School/Java/CZ2002_Assignment/src/" Rather than declaring the same Filepath in every single class, is it possible to simply have a "global" type of variable of this FilePath so that all classes can access it and I only need to declare and update it once. Thanks

  I'm using Python's subprocess.communicate() to read stdout from a process that runs for about a minute. How can I print out each line of that process's stdout in a streaming fashion, so that I can see the output as it's generated, but still block on the process terminating before continuing? subprocess.communicate() appears to give all the output at once.

• How do I disable auto- poster image generation on the video tag?

  - by ekallevig

  I'm using the 'poster' attribute on a video tag and the way it seems to work at least in webkit browsers is that it loads the poster image and then once enough of the video has loaded, it replaces that poster with an auto-generated poster from the video file itself. However, my poster images don't match the auto-generated posters which results in a weird experience of one image loading, then being replaced in a few seconds by the auto-generated image. Is there any way to prevent the auto-generated image from being used?

• Scope of const char*

  Consider this code: const char* someFun() { // ... some stuff return "Some text!!" } int main() { { // Block: A const char* retStr = someFun(); // use retStr } } My question is in the function sumFun() where is "some Text!!", stored (i think may be in some static area in ROM) and what will be its scope? Will the memory pointed by retStr be occupied throughout the program or be released once the block A exits? -- Thanks

  - by Eric J.

My goal is to provide a web page that plays a video and then asks the user a question about the video once playback is complete.
