  • Subterranean IL: Exception handling 2

    - by Simon Cooper
    Control flow in and around exception handlers is tightly controlled, due to the various ways the handler blocks can be executed. To start off with, I'll describe what SEH does when an exception is thrown. Handling exceptions When an exception is thrown, the CLR stops program execution at the throw statement and searches up the call stack looking for an appropriate handler; catch clauses are analyzed, and filter blocks are executed (I'll be looking at filter blocks in a later post). Then, when an appropriate catch or filter handler is found, the stack is unwound to that handler, executing successive finally and fault handlers in their own stack contexts along the way, and program execution continues at the start of the catch handler. Because catch, fault, finally and filter blocks can be executed essentially out of the blue by the SEH mechanism, without any reference to preceding instructions, you can't use arbitary branches in and out of exception handler blocks. Instead, you need to use specific instructions for control flow out of handler blocks: leave, endfinally/endfault, and endfilter. Exception handler control flow try blocks You cannot branch into or out of a try block or its handler using normal control flow instructions. The only way of entering a try block is by either falling through from preceding instructions, or by branching to the first instruction in the block. Once you are inside a try block, you can only leave it by throwing an exception or using the leave <label> instruction to jump to somewhere outside the block and its handler. The leave instructions signals the CLR to execute any finally handlers around the block. Most importantly, you cannot fall out of the block, and you cannot use a ret to return from the containing method (unlike in C#); you have to use leave to branch to a ret elsewhere in the method. As a side effect, leave empties the stack. catch blocks The only way of entering a catch block is if it is run by the SEH. At the start of the block execution, the thrown exception will be the only thing on the stack. The only way of leaving a catch block is to use throw, rethrow, or leave, in a similar way to try blocks. However, one thing you can do is use a leave to branch back to an arbitary place in the handler's try block! In other words, you can do this: .try { // ... newobj instance void [mscorlib]System.Exception::.ctor() throw MidTry: // ... leave.s RestOfMethod } catch [mscorlib]System.Exception { // ... leave.s MidTry } RestOfMethod: // ... As far as I know, this mechanism is not exposed in C# or VB. finally/fault blocks The only way of entering a finally or fault block is via the SEH, either as the result of a leave instruction in the corresponding try block, or as part of handling an exception. The only way to leave a finally or fault block is to use endfinally or endfault (both compile to the same binary representation), which continues execution after the finally/fault block, or, if the block was executed as part of handling an exception, signals that the SEH can continue walking the stack. filter blocks I'll be covering filters in a separate blog posts. They're quite different to the others, and have their own special semantics. Phew! Complicated stuff, but it's important to know if you're writing or outputting exception handlers in IL. Dealing with the C# compiler is probably best saved for the next post.

  • How to make Unity's Dash save the results filtering?

    - by Vagrant232
    The dash can remember the settings for filtered results for the entire session, but not beyond that. Once the profile is logged out and back in the results would reset to their original settings; displaying all the results without filtering. How can I make the results filtering more permanent? IE: How to make the photo lens for instance always show photos from "This Computer" and not from Picasa or Facebook across sessions and not just temporarily?

  • How do I save files with libgdx so that users can't read them?

    - by Rudy_TM
    Writing my game in libgdx, I arrived at the point when I need to save the player stats and the info of the levels. However, in libgdx it's not allowed to write the file inside folder of the application, only external (on the SD) is allowed. The point is that I don't want the file to be seen by anyone, or if they can see it, how can I convert it to a binary file so it's not human readable? I just want to hide the file.

  • How to continue an HTTrack mirroring session from the command line?

    - by isme
    I want to drive my mirroring project using the Command Prompt instead of the WinHTTrack interface so that I can script and schedule the mirroring session more easily. The output of httrack --help gives a simple command for continuing an interrupted mirroring session: example: httrack --continue continues a mirror in the current folder When I try httrack --continue in my HTTrack project folder, all I get is output like this: Example: -%F "<!-- Mirrored from %s by HTTrack Website Copier/3.x [XR&CO'2010], %s -->" * Option %F needs to be followed by a blank space, and a footer string With each parameter on a new line for readability, the first line of my doit.log file looks like this: -qiC1%P0s0b0u1j0%s%u0N0%I0p1DaK0c1T30H0%kf2E1800A25000%c0.1%f#f -F "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" -%F "" -%l "en, en, *" http://saa.gov.uk/search.php?SEARCHED=1&SEARCH_TABLE=council_tax&SEARCH_TERM=City+of+Edinburgh&DISPLAY_COUNT=100 -O1 "C:\\Users\\Iain\\Projects\\Council Tax Analysis\\Code\\HTTrack\\Council Tax Valuation List" -* \ +*search.php?SEARCHED=1* -*DISPLAY_MODE=FULL* The parameter %F "" should tell HTTrack to use an empty footer. I used the WinHTTrack interface to create the project and start the mirroring session. I can interrupt and continue the mirroring session using the interface. The HTML files saved by WinHTTrack have no footer.

  • What changed between Excel 2007 and 2010 that is causing my copied worksheet save to fail?

    - by snorehorse
    When I do this in Excel 2010 this fails, but works in Excel 2007: Create a new workbook and insert an image onto a worksheet, or get a preexisting worksheet with an image. Copy the worksheet into a new workbook by clicking the worksheet tab and clicking Move Or Copy and then choosing (new workbook) as the destination. Close the source workbook. Attempt to save the new workbook. The message is: "Errors were detected while saving 'myfilepathhere.xlsx'. Microsoft Excel may be able to save the file b removing or repairing some features. To make the repairs in a new file, click Continue. To cancel saving the file, click Cancel". Clicking continue brings up another file dialog window followed by more repair errors. It seems behind the scenes it is looking to the source workbook when it tries to save the image in the new destination workbook. No useful error message, of course, thanks microsoft. But this problem never happened in Excel 2007. The reason why I am closing the source notebook before the save, is because I don't need the end user to see it after I programmatically pull a coversheet (with the image) from it, in an interop app. Thanks for any help. Update: I don't encounter this problem if I open the source workbook as "Read Only" (I do this programmatically using Excel Interop).

  • ASP.NET resseting SessionID cookie when cookie expiration date is set

    - by Sergej Andrejev
    I have two pages: Default.aspx and WebForm1.aspx. One of these pages stores a session variable which works fine until I add code which ads expiration date to SessionID cookie. What happens is: Open default.aspx Set-Cookie ASP.NET_SessionId=14jhsdfq23jkh13jkh12k1; expires=Fri, 19-Mar-2010 07:31:47 GMT; path=/ Click on link to open WebForm1.aspx No cookies set Click on link to open Default.aspx (Cookie is reset) Set-Cookie ASP.NET_SessionId=; expires=Fri, 19-Mar-2010 07:31:47 GMT; path=/ So the question would be how should I set SessionID cookie expiration date correctly?

  • How to set icon to title bar for each Activity in Tablelayout in android

    - by Venu Gopal
    In my tablayout example, i have created 3 tabs, as usually i set 3 activities for each tab. I can set image to title bar of activity, which adds the intent to each tab. Due to this, the image in the title bar is visible in all 3 tabs. My requirement is to set a different image to title bar for each activity. I followed this to set image to title bar. But when i am going to do the same thing to each activity, getting android.util.AndroidRuntimeException: You cannot combine custom titles with other title features this error and application is terminated. manifest.xml <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.aptitsolution.tablayout" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/MyTheme"> <activity android:name=".TabLayoutDemo" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="AlbumsActivity"></activity> <activity android:name="ArtistsActivity"></activity> <activity android:name="SongsActivity"></activity> TabLayoutDemo.java public class TabLayoutDemo extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); setContentView(R.layout.main); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.my_title); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, ArtistsActivity.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); .... ....

  • Is there a way to bypass the jQuery error handler?

    - by oravecz
    If my Ajax call returns a successful result, but while processing the result I cause an exception, the error handler fires. This seems counter intuitive to me as I think the error handler should only fire when an error occurs as a result of making the Ajax call or via a server-side error. I am trying to use the Ajax function in a unit test so I would like to tell the difference between the two different failure scenarios.

  • Set page size using WIA (with scanner)

    - by Salvador Sarpi
    Hello, I'm using WIA to acquire images from a scanner with C#. I can scan the papers, but I can't set up the page size correctly, it always defaults to A4 and I need to use Letter or Legal sometimes. I tried with the WIA_DPS_PAGE_SIZE property, but when I try to set a value, I always get an error, that the value is out of the interval (tried a lot of possible values). I wan't to be able to use WIA_DPS_PAGE_SIZE = WIA_PAGE_AUTO (for automatic page size), but I can't find anything on the web related to this. Does anyone know a solution? thanks!

  • How to set foreground Window from Powershell event subscriber action

    - by guillermooo
    I have a FileSystemWatcher instance running in the background of my PoSh session watching for changes to text files. A PoSh event subscriber is attached to this event and, when fired, it launches a console program by calling Start-Process. This program steals de focus from the current foreground window (my PoSh console). Calling SetForegroundWindow from the PoSh event subscriber to return the focus to my PoSh console doesn't work. SwitchToThisWindow does work most of the time, but according to the MSDN docs, it shoulnd't be used. Can I prevent Start-Process from stealing the focus in this situation or set it back from the event subscriber to the window that had it before this event is fired?

  • WPF DataTemplate Trigger set a property in a different DataTemplate

    - by Burt
    I have 2 DataTemplates (A & B). A contains an expander and the expander's HeaderTemplate is pointed at another DataTemplate (B). DataTemplate B is shown below: <DataTemplate x:Key="ProjectExpanderHeader"> <Border CornerRadius="2,2,0,0" Background="{StaticResource ItemGradient}" HorizontalAlignment="{Binding HorizontalAlignment, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContentPresenter}}, Mode=OneWayToSource}"> <local:ItemContentsUserControl Height="30"/> </Border> </DataTemplate> Is it possible to set the CornerRadius of B's Border when the IsExpanded property of A's Expander is set to true? Thanks in advance.

  • Set Proxy Credential in Web Browser Control

    - by rockacola
    I am working on a legacy code where an application uses AxSHDocVw.AxWebBrowser (NOT System.Windows.Forms.Control) to open up web pages and am extending it to take proxy into considerations. I have following example on http://www.pinvoke.net/default.aspx/wininet/internetsetoption.html to use InternetSetOption() to go through specified proxy and tested that it works. Now the hurdle is I tried everything but failed to pass username and password with following code: //-- Set Proxy Username bool resultF = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY_USERNAME, username, username.Length+1); var errorF = Marshal.GetLastWin32Error(); //-- Set Proxy Password bool resultG = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY_PASSWORD, password, password.Length+1); var errorG = Marshal.GetLastWin32Error(); Both resultF and resultG return true and has no errors but it still working. Any hint on what may be happening here? and what method do I have to debug this? Thanks in advance.

  • Generating a KML heatmap from given data set of [lat, lon, density]

    - by Will Croft
    I am looking to build a static KML (Google Earth markup) file which displays a heatmap-style rendering of a few given data sets in the form of [lat, lon, density] tuples. A very straightforward data set I have is for population density. My requirements are: must be able to feed in data for a given lat, lon must be able to specific the given density of the data at that lat, lon must export to KML The requirements are language agnostic for this project as I will be generating these files offline in order to build the KML used elsewhere. I have looked at a few projects, most notably heatmap.py, which is a port of gheat in Python with KML export. I have hit a brick wall in the sense that the projects I have found to date all rely on building the heatmap from the density of [lat, lon] points fed into the algorithm. If I am missing an obvious way to adapt my data set to feed in just the [lat, lon] tuples but adjusting how I feed them using the density values I have, I would love to know!

  • Headers to set for AJAX calls in a custom webserver

    - by ErJab
    I'm writing a custom web server. When I enter the URL of my server in the browser, I get the sample text I write out to the socket in my browser correctly. This is the HTTP response that I write: HTTP/1.1 200 OK\r\n Server: My Server\r\n Date: Blah\r\n \r\n This is some sample text. This appears in my browser correctly when I connect directly to the server entering the URL. However, if I use Ajax (jQuery) to access the same URL and then set the innerHTML of an element on the HTML page, I do not get any data printed. Is there any other header I need to set on my web server so that the browser's XMLHttpRequest object detects the response?

  • Set form field values in ExtJS

    I'm using ExtJS to create a formPanel: new Ext.FormPanel({ labelAlign: 'top', title: 'Loading Contact...', bodyStyle:'padding:5px', width: 600, autoScroll: true, closable: true, items: [{ layout:'column', border:false, items:[{ columnWidth:.5, layout: 'form', border:false, items: [{ xtype:'textfield', fieldLabel: 'First Name', name: 'first_name', id: 'first_name', anchor:'95%' }, { xtype:'datefield', fieldLabel: 'Birthdate', name: 'birthdate', width: 150, }] },{ columnWidth:.5, layout: 'form', border:false, items: [{ xtype:'textfield', fieldLabel: 'Last Name', name: 'last_name', anchor:'95%' },{ xtype:'textfield', fieldLabel: 'Email', name: 'email', vtype:'email', anchor:'95%' }] }] },{ xtype:'tabpanel', plain:true, activeTab: 0, height:300, /* * By turning off deferred rendering we are guaranteeing that the * form fields within tabs that are not activated will still be * rendered.

Thanks
