  • Analysing objects generated by a Java application in between GCs.

    - by elec
    Is there a tool which could be used to analyse the objects being created between two separate garbage collection run (= number of objects created and their type) ? Heapdumps dont really work here as they perform a GC when they're invoked (or at least that's what I observed everytime so far), and I want to see which objects are collected by the GC, not which objects are left after the GC run, if that makes sense. ...or is it possible somehow to inspect the nature and size of objects being collected by the garbage collector ?

  • Delay-Load equivalent in unix based systems

    - by saran
    What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

  • Combining the value of GetLastError and a custom error message

    - by Jessica
    I have a function that returns a different DWORD value for each case there is an error. So I have the following defines: #define ERR_NO_DB_CONNECTION 0x90000 #define ERR_DB_NOT_OPEN 0x90001 #define ERR_DB_LOCKED 0x90002 #define ERR_DB_CONN_LOST 0x90003 Now, I return those values when an error occurs. I need to also return the value of GetLastError in the same return. No, I can't read it later. I tried combining it different ways, eg: return ERR_DB_NOT_OPEN + GetLastError(); and then extract the error by subtracting the value of ERR_DB_NOT_OPEN but since I need to use this in functions where there can be several return values it can get quite complex to do that. Is there any way to achieve this? I mean, combine the value + GetLastError and extract them later? Code is appreciated. Thanks Jess.

  • ActionScript display zero value

    - by bwong
    It seems the number Datatype handles zeros and nulls the same. I need to display a zero value on the screen, but AS displays nothing. When it's saved, the value is saved as a zero, and therefore shows up zero on the screen. Is there a way to display the zero value using a new object? public class myObject{ private var numVar:Number } My AS file: var temp:MyObject temp.numVar = 0; When I debug, temp.numVar contains a value of 0, but does not show anything on the UI. If this object is then saved to the DB, and then displayed to the UI, it shows a 0. My question is - how do I get temp.numVar to display 0 before persistenting it to the DB?

  • Eror while showing returned value on parent window from chield (Dialog box) window using JSF Trinida

    - by Navnath
    Hi There, I am using Myfaces and Trinidad tld's for page design. In that, I am trying to implement Dialog box which will going to open on button click with tacking some value from parent window and return result to Parent window. Now the problem is I can send value to Dialog box and also get return from dialog box successfully, but there is problem to show return value on Parent window because parent window is not reflecting that value and ask for refresh page. When I refresh page, it again open the pop up, i.e. it resending the previous request. Here is my return code. private UIXInput input; public UIXInput getInput() { return input; } public void setInput(UIXInput input) { this.input = input; } public void returned(ReturnEvent event) { if (event.getReturnValue() != null) { getInput().setValue(event.getReturnValue()); RequestContext afContext = RequestContext.getCurrentInstance(); afContext.addPartialTarget(getInput()); } } Next is I have bind input variable with field which need to reflect return value. Here is .jspx code. I have download Trinidad dialog code and try to run on local system, but it not showing any dialog box. But once I remove partialSubmit="true" attribute from comment button which shows dialog box, Then I can see dialog box. Is this attribute making an above error? I hope I have explain my problem clearly. Please...Please let me know any any kind of solution, suggestion. I have spend almost a week to resolve this issue, but.......didn't succeed. Thank You in advance, Navnath Kumbhar.

  • jQuery: if value is true without user action

    - by Kevin Brown
    I want to show a div if the value of an input =='CP'. Right now this is my code: $(".register-type").change(function(){ var value = $(this).val(); if(value == 'CP'){ $('.cp-show').show(); This works fine if they change the input, but if things get validated false and the page reloads, this input is still 'CP', but the div doesn't show... Is there a way to correct this so that jquery checks if this is set on the page load?

  • Memory Allocation by STL C++ Objects

    - by Vaibhav
    I am using malloc_stats() function to display the amount of "system bytes" and "in use" bytes used by the process. I wanted to know if the in use bytes also include the memory used by STL C++ Objects like map, vector, sets? If yes, is it safe to assume that this is only amount of memory that will be used by the process?

  • Visual Studio keeps inserting absurd default property value in designer file

    - by Bugz R us
    i have a simple usercontrol with following properties: public partial class RichTextEditorControl : UserControl { public string EditorText { get { return richTextBox1.Rtf; } set { richTextBox1.Rtf = value; } } public string EditorPlainText { get { return richTextBox1.Text; } set { richTextBox1.Text = value; } } } Now whenever I EDIT a form which contains this control, VS fills its designer file with the following code line, and then throws a designer error : this.richTextEditorControl1.EditorPlainText = global::Project.Resources.MyResources_de_DE.SomeString; Now I don't know where it gets this value from ??? I've searched entire solution, and nowhere there's mention of this var, except for 1 file, where it's needed ... Moreover, the code VS writes, has an error in it ?! It doesn't compile ... The only thing I can do is edit the designer file, but the next time I have to edit the form with the designer, the same error happens again ... Where on earth is VS getting this value from ??

  • Use from value from backing bean in javascript

    - by AlfonsSocken
    What I want is to use a boolean value from applicationContext.xml (Jboss configuration file) in my javascript. Currently I use Spring to inject a value configured in applicationContext.xml into my backingbean. Then I put an output text in my jsp like this <h:outputText id="idValue" styleClass="foo" value="" rendered="#{bean.isRendered}"/> In my JavaScript I try following jQuery(function(){ bRedirect = jQuery("#foo").value != undefined; ... All this looks so terrible to me, even though it works fine. There must be a smarter way than doing what I do. Note that I am running JSF1.2 and therefore must use jQuery instead of $ and also select by unique class (foo) and not by id, which may be bad practice as well. Thank you in advance. alfons

  • Name Value Pairs in a ComboBox

    - by JamesB
    I'm convinced this must be a common problem, but I can't seem to find a simple solution... I want to use a combobox control with name value pairs as the items. ComboBox takes TStrings as its items so that should be fine. Unfortunately the drawing method on a combobox draws Items[i] so you get Name=Value in the box. I'd like the value to be hidden, so I can work with the value in code, but the user sees the name. Any Ideas?

  • What is the best way of inserting a datetime value using dynamic sql

    - by jaffa
    What is the best way of inserting a datetime value using a dynamic sql string, whilst at the same time being able to handle the possibility of the value being null? The current statement inserts into a table from a select statement built using a string. The datetime value is stored in a parameter and the parameter is used in the select. Like so: set @execsql = 'Insert into ( start_date ) SELECT ( ''' + CAST(start_date as VARCHAR) + ''' + ')'
