• Click a button on an MS Access form from C# using Access Interop

  - by Az

  Hi, I can connect to the access database and run functions etc from c#, I can even get a hold of the button I need to click, but I can't make it think it's been clicked. nonManagedDb.DoCmd.OpenForm("frmMaintenance", Access.AcFormView.acNormal, MissingVal, Access.AcFormOpenDataMode.acFormReadOnly, Access.AcWindowMode.acWindowNormal, MissingVal); var RunRep = (CommandButton)nonManagedDb.Forms["frmMaintenance"].Controls["btnDailySheetsReport"]; That's as afar as I've gotten with this, I've tried reflection to grab it's event and invoke it but it's classed as a COM object only so that's out.

• having trouble with zooming in android webview

  - by Talha

  I'm new to android. I'm using webview in scrollview to display my local html page (html has text only). I created two buttons for zoomin and zoomout using behind function zoomIn() & zoomOut() respectively. These functions work fine. The problenm is, when I zoom in, some of the text goes out from both top and bottom and it doesn't appear when I scroll. How can I resolve this?

• How do I create and read non-global variables that aren't destroyed at end of function?

  - by Paul Reilly

  I am attempting to code some plugins to use with MIDI sequencers but have hit a stumbling block. I can't use global-scope variables to store information because multiple instances of the .dll can exist which share memory. How do I create a class (for re-usability purposes in other plugins) containing 2 dimensional array and other variables the content of which is to be shared between functions? If that is possible, how would I read and write the data from the function in the framework where I do the processing?

• How do I prevent use of beta classes from google guava library?

  - by mjlee

  We have been using Google collections in the production for several months. We would like to start using guava for additional functions. However, I'm afraid to bring guava into our product stack b/c some developers may start to use 'beta' classes. We have various unit-tests in our code but at this point, I prefer not to include 'beta' class b/c it is subject to change in the future. Is there any easy way to do detect if the project includes any 'beta' guava classes?

• C#: Can you detect whether or not the current execution context is within `lock (this)`?

  - by John Gietzen

  If I have an object that I would like to force to be accessed from within a lock, like so: var obj = new MyObject(); lock (obj) { obj.AddOne(); obj.RemoveOne(); } Is it possible, from within the AddOne and RemoveOne functions to detect whether the current execution context is within a lock? Something like: Monitor.AreWeCurrentlyEnteredInto(this)

• Decorator Design Pattern - Not Possible

  - by Lennie

  Hi, This is more a design question... You can't do a decorate design pattern if: 1) The object is marked "sealed" meaning you can't extend from it. 2) or you want to override a method but its not virtual. What can you do then? Taken that you can't change the class source code if you don't have the source code (like a 3rd party library).

• Linux C++: how to profile time wasted due to cache misses?

  - by anon

  I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

• mySQL query: How to insert with UNION?

  - by Industrial

  Hi everybody, I am kind of new to mySQL:s union functions, at least when doing inserts with them. I have gotten the following to work based upon a example found on the net: INSERT INTO tableOne(a, b) SELECT a, $var FROM tableOne WHERE b = $var2 UNION ALL SELECT $var,$var Ok, nothing strange about that. But what happens when I want to insert a third value into the database that has nothing to do with the logic of the Select being done? Like : INSERT INTO tableOne(a, b, c ) How could that be done?

• The ultimate browser testing machine...

  - by Mazzi

  Hi All, What would be the ultimate web application browser compatibility test machine be? The testing environment would be (XP: IE6,FF3.6), (XP: IE7,Chrome), (XP: IE8,Safari), (MacOsX: Safari, FF3.6, Chrome), (Ubuntu: FF3.6, Chrome) Of course I want it all in one machine, my initial thought was Using a MacOsX as a host machine and use virtual box to install 3 xp and one ubuntu on it. Do you think it is an optimal solution? Do you have any better solution to achieve the above?

• How to execute a program from file descriptor?

  - by stribika

  I need to execute a file when I only know the descriptor. It is also possible that there are no links to the file so finding out the name somehow is not an option. All the execve(), execvp(), etc functions take a file name. dlopen() also takes a name. Ugly solutions (like reading the file and calling some function pointer) are OK.
