  • How can I tell Visual Studio to NOT BREAK on a particular exception?

    - by Noel Kennedy
    I have a particular type of exception that I would like Visual Studio to not catch with the Exception Assistant. Essentially I would like it just to let my normal exception handling infrastructure deal with it. The exception is an inheritor of System.Exception which I wrote and have the source code for. Any where this is thrown I want VS to not catch it, ie it is not useful to just supress a single throw new BlahException(); in code. This is because the exception is thrown a lot, and I don't want to have to supress every single instance individually. In case it makes a difference I am on Visual Studio 2010 Ultimate, Framework 3.5 SP1.

  • How do I tell cmake to do these two steps to use winpcap?

    - by Gtker
    Quoted from here: If your program uses Win32 specific functions of WinPcap, remember to include WPCAP among the preprocessor definitions. If your program uses the remote capture capabilities of WinPcap, add HAVE_REMOTE among the preprocessor definitions. Do not include remote-ext.h directly in your source files. Has anyone managed to use winpcap with cmake?

  • Can I tell if the iPhone has a passcode?

    - by tewha
    I'm developing an application that asks for a PIN when you start it. That's not great, but I can live with it. The problem is I'm being asked to ask for the PIN each time the phone wakes from sleep, too. Combined with the OS asking for its passcode, it's too much. Is there any legitimate way to detect if the phone has a passcode required for waking, so I can skip requiring a PIN in this case? I don't want to know the PIN and I don't actually care if it was locked (for instance, if the phone was asleep very briefly), I just want to know that the data is in some way "protected."

  • How to tell where I am in an array with pointer arythmetic?

    - by klez
    In C, I have declared a memory area like this: int cells = 512; int* memory = (int*) malloc ((sizeof (int)) * cells); And I place myself more or less in the middle int* current_cell = memory + ((cells / 2) * sizeof (int)); My question is, while I increment *current_cell, how do I know if I reached the end of the allocated memory area?

  • Android: how can i tell if the soft keyboard is showing or not?

    - by binnyb
    Heres the dilemma: I am showing a screen with 3 input fields and 2 buttons inside of a tab(there are 3 tabs total, and they are on the bottom of the screen). the 2 buttons are set to the bottom left and right of the screen, right above the tabs. when i click on an input field, the tabs and buttons are all pushed up on top of the keyboard. i desire to only push the buttons up, and leave the tabs where they originally are, on the bottom. i am thinking of setting the visibility of the tabs to GONE once i determine that the soft keyboard is showing, and visibility to VISIBLE once the soft keyboard is gone. is there some kind of listener for the soft keyboard, or maybe the input field? maybe some tricky use of OnFocusChangeListener for the edit text? How can i determine whether the keyboard is visible or not?

  • How can I tell what events fire from GXT?

    - by CoverosGene
    I cannot seem to find any documentation of what events fire and when in GXT. The API docs have lists of all the events that could fire (in Events). And it describes how to handle events that you catch. But I'm interested in the opposite side, which events are fired when I take a certain action. I can set some listeners for various different components, or I can use addListener with a specific event code to catch individual events. That's spotty, and I seem to be using trial-and-error to guess what I might want to catch. Is there a way to log all the events that are firing? Or catch all of them so I could look at them in a debugger? Or is there some documentation I am missing that has the information? Something along the lines of "when you click on a widget, a ButtonEvent is fired. Events.x is fired on the hover, Events.y on the click."

  • How can I tell if a byte array has already been compressed?

    - by MikeG
    Hi, Can I rely on the first few bytes of data compressed using the System.IO.Compression.DeflateStream in .NET always being the same? These bytes seem to always be the 1st bytes: 237, 189, 7, 96, 28, 73, 150, 37, 38, 47 , ... I'm assuming this is some kind of header, I'd like to assume that this header is fixed and isn't going to change. Has anyone got any extra info about this? Background info (The reason I want to know this info is...) I have a load of data in a database table that could do with being made smaller. I've decided I'm going to start compressing the data and not going to bother compressing the existing data. When the data gets into my .NET code the data is a String. I'd like to be able to look at the 1st few bytes of the string and see if it has been compressed, if it has then I need to de-compress it. I was originally thinking I could convert the string to bytes and just try de-compressing the data. Then if an exception happens, I could just assume it wasn't compressed. But I think checking the header bytes would give me much better performance. Many thanks, Mike G

  • What's the best way to tell if the mouse is over a form or not?

    - by cyclotis04
    I figured out how to capture mouse clicks over the entire form, but this method doesn't translate well for MouseEnter and MouseLeave. My form layout is made up from many Panels and TableLayoutPanels so there's no all-encompassing control I can monitor events for, and obviously a MouseLeave event for a button doesn't mean the cursor left the entire form. Has anyone figured out a good way to get around this?

  • What is the correct way to tell if Pango has found the right font?

    - by Thedward
    I create a font description with: pango_font_description_from_string() Then load a font with: pango_context_load_font() This process seems to result in some default font regardless of the string I give it. Is there any sane way for me to determine if the returned font is the result of an alias (e.g. "Sans", "Monospace") or just the last chance default font? For example, if I request the font "Monospace" and get back "DejaVu Sans Mono" then I should be able to declare that a good match. However, if I request "OquieZee" and get back "DejaVu Sans" then I'd like to know that I just got back the default font because the font I requested doesn't actually exist on the system. When I first saw pango_font_description_better_match() I thought it might be of help, but it turned out to be a dead end.

  • How can I tell when a MySQL table was last updated?

    - by RaGE
    In the footer of my page, I would like to add something like "last updated the xx/xx/200x"; with this date being the last time a certain mySQL table has been updated. What is the best way to do that ? Is there a function to retrieve the date ? Should I make an access to the database everytime my footer is displayed ?

  • Can I tell Borland C++ Builder to copy a file somewhere else after it is built?

    - by MrVimes
    I have two computers. One is intended to be left 'free' for high-performance activities (such as playing games) The other is my 'all purpose' computer where I install all the apps I use for creating things, and so on. On the second computer I use Codegear C++ Builder to work on an app that I use on the first computer. If I have BCB compile to comp 1 it is hopeless. It becomes unresponsive. It compiles locally very quickly. So what I do is compile locally and then copy the exe to the other machine. Well, I'm all for streamlining processes, so I want a way to compile on PC2 and use on PC1 without any intermediate steps. So is it possible to have BCB do the compiling on PC2 and create a local exe file, then copy the file to PC 1?

  • How can I tell if a <script> tag with a given src attribute is present on the page in ASP.net?

    - by Chris McCall
    Like the title says, I'm trying to find out if I need to include a script library that my ASP.net UserControl needs to work. I don't want to include it multiple times per page, but I want my control to be able to be used multiple times on the same page. How can I, in the codebehind of my control, check to see if a given <script/> tag is present? This is .Net 2.0, no LINQ.

  • C# Reflection - How can I tell if object o is of type KeyValuePair and then cast it?

    - by Logan
    Hi All I'm currently trying to write a Dump() method from LinqPad equivalent iin C# for my own amusment. I'm moving from Java to C# and this is an exercise rather than a business requirement. I've got almost everything working except for Dumping a Dictionary. The problem is that KeyValuePair is a Value type. For most other Value types I simply call the ToString method but this is insufficient as the KeyValuePair may contain Enumerables and other objects with undesirable ToString methods. So I need to work out if it's a KeyValuePair and then cast it. In Java I could use wildcard generics for this but I don't know the equivalent in C#. Your quest, given an object o, determine if it's a KeyValuePair and call Print on its key and value. Print(object o) { ... } Thanks!

  • rails 3, active record: any way to tell how many unique values match a "x LIKE ?" query

    - by jpwynn
    I have a query to find all the phone numbers that match a partial expression such as "ends with 234" @matchingphones = Calls.find :all, :conditions => [ "(thephonenumber LIKE ?)", "%234"] The same phone number might be in the database several times, and so might be returned multiple times by this query if it matches. What I need is to know is UNIQUE phone numbers the query returns. For example if the database contains 000-111-1234 * 000-111-3333 000-111-2234 * 000-111-1234 * 000-111-4444 the existing query will return the 3 records marked with * (eg returns one phone number -1234 twice since it's in the database twice) what I need is a query that returns just once instance of each match, in this case 000-111-1234 * 000-111-2234 *

  • How can I tell xCode to recheck project resources that have been modified?

    - by Nick
    I'm working with a designer friend on an iPhone app and he likes to refine all sorts of images relating to the project we're working on. All these images have been added to the project previously (and added to the project folder by xcode) and then are modified in their new location. When I preview the images in xCode, the updated images show up but building and running in the simulator or on a device doesn't pick up the new image. In fact, if I do a clean build it seems to ignore the image all together and blank spaces appear where images should be. Now, I can delete these files from the project and re-add them and everything works peachy again. But there are a lot of them and I'd rather not do that every time an image is updated. Is there a way to get xCode to review and "learn" about these modified images? Is there a good reason for why it's not doing that automatically?

  • Can anyone tell me what is wrong with my create trigger syntax?

    - by Travis
    I am experimenting with triggers for the first time. When I try to create a trigger using the following: CREATE TRIGGER t_foldersPrivate BEFORE DELETE ON foldersPrivate FOR EACH ROW BEGIN DELETE FROM programs WHERE folderType = '0' AND folderID = OLD.ID; END; I receive the following error: `1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3` (mysql 5.1.37) If I get rid fo the delete statement the create trigger statement works fine. So I am assuming it must have something to do with that. But for the life of me I'm not sure what...

  • How can I tell if an ADODB::_RecordsetPtr has already been created?

    - by scottm
    I am trying to write a class that uses ADO to retrieve SQL records. The intent is for the class to maintain one private recordset an other methods move forward, retrieve fields, etc. This is a basic example of my class: class SqlADO { private: ADODB::_RecordsetPtr m_recordset; public: void Open(); //open the connection void Execute(const char* sql); // creates or replaces current recordset void Next(); //moves recordset cursor forward void Field(const char* fieldName); //retrieves field name from current record of the recordset }; My Questions: In the Execute method, how can I check to see that the recordset instance has been created (or do I need to) so that I can close it first? Do you know of any good ADO COM Interop references?
