  • VBScript Catching Erroring Varialble Value

    - by Soren
    I have a VB Script (.vbs file) that is just a simple directory listing of a drive. It will the base of a drive back up script. But when running it as it is below, I am getting a Permission Denied error on some folder. What I need to find is what that folder is so I can figure out what the problem is with the folder. The line that is giving the error is "For Each TempFolder In MoreFolders". So what I am trying to figure out is how to WScript.Echo the current path (objDirectory) if there is an error. I am not sure if it matters much, but just in case, the error that I am getting is Permission Denied 800A0046 on line 12. So some folder, I do not know which one, is not letting me look inside. Set WSShell = WScript.CreateObject("WScript.Shell") Set objFSO = CreateObject ("Scripting.FileSystemObject") Dim FolderArr() FolderCount = 0 TopCopyFrom = "G:\" Sub WorkWithSubFolders(objDirectory) Set MoreFolders = objDirectory.SubFolders 'The next line is where the error occurs (line 12) For Each TempFolder In MoreFolders FolderCount = FolderCount + 1 ReDim Preserve FolderArr(FolderCount) FolderArr(FolderCount) = TempFolder.Path ' WScript.Echo TempFolder.Path WorkWithSubFolders(TempFolder) Next End Sub ReDim Preserve FolderArr(FolderCount) FolderArr(FolderCount) = TopCopyFrom Set objDirectory = objFSO.GetFolder(TopCopyFrom) WorkWithSubFolders(objDirectory) Set objDirectory = Nothing WScript.Echo "FolderCount = " & FolderCount WScript.Sleep 30000 Set objFSO = Nothing Set WSShell = Nothing

  • COM: How to handle a specific exception?

    - by Ian Boyd
    i'm talking to a COM object (Microsoft ADO Recordset object). In a certain case the recordset will return a failed (i.e. negative) HRESULT, with the message: Item cannot be found in the collection corresponding to the requested name or ordinal i know what this error message means, know why it happened, and i how to fix it. But i know these things because i read the message, which fortunately was in a language i understand. Now i would like to handle this exception specially. The COM object threw an HRESULT of 0x800A0CC1 In an ideal world Microsoft would have documented what errors can be returned when i try to access: records.Fields.Items( index ) with an invalid index. But they do not; they most they say is that an error can occur, i.e.: If Item cannot find an object in the collection corresponding to the Index argument, an error occurs. Given that the returned error code is not documented, is it correct to handle a specific return code of `0x800A0CC1' when i'm trying to trap the exception: Item cannot be found in the collection corresponding to the requested name or ordinal ? Since Microsoft didn't document the error code, they technically change it in the future.

  • CustomErrors section does not handle 404 properly on production server

    - by Adrian Grigore
    Hi, I'd like my ASP.NET MVC application to redirect failed requests to matching action methods of a certain controller. This works fine on my development machine running Windows 7, but not on my production machine running Windows 2008 R2. I set up my web.config as follows: <customErrors mode="On" defaultRedirect="/Error/ServerError/500"> <error statusCode="403" redirect="/Error/AccessDenied" /> <error statusCode="404" redirect="/Error/FileNotFound" /> </customErrors> This customErrors section works fine on both of my machines (production and development) for 500 Internal Server errors. It also works fine for 404 errors on my development machine. However, it does not properly redirect 404 errors on the production machine. Instead of /Error/FileNotFound, I get the standard 404 page that comes with IIS 7. What could be the problem here?

  • Rest WebService error handling.

    - by Pratik
    Hi there, I am using RestWebservice for few basic operations , like creating/searching. The request xml looks something like this <customer> <name/> ..... </customer> For a successful operation I return the same customer XML with extra fields populated in it(eg. systemId etc which we blank in the request) . with Response.Status=2000 For an unsuccessful operation i return something like this with different error codes . e.g Response.Status = 422(Unprocessable entity) Response.Status= 500(Internal Server Error) and few others.. <errors> <error> An exception occurred while creating the customer</error> <error> blah argument is not valid.</error> </errors> Now i am not sure , whether this is the correct way of sending the errors to the client. Maybe it should be present in the header of the response. I will really appreciate any help. Thanks!

  • WCF events in server-side

    - by Eisenrich
    Hi all, I'm working on an application in WCF and want to receive events in the server side. I have a web that upon request needs to register a fingerprint. The web page request the connection of the device and then every second for 15 seconds requests the answer. The server-side code is apparently "simple" but doesn't work. Here is it: [ServiceContract] interface IEEtest { [OperationContract] void EEDirectConnect(); } class EETest : IEEtest { public void EEDirectConnect() { CZ ee = new CZ(); // initiates the device dll ee.Connect_Net("192.168.1.200", 4011); ee.OnFinger += new _IEEEvents_OnFingerEventHandler(ee_OnFinger); } public void ee_OnFinger() { //here i have a breakpoint; } } every time I put my finger, it should fire the event. in fact if I static void Main() { EETest pp = new EETest(); pp.EEDirectConnect(); } It works fine. but from my proxy it doesn't fire the event. do you have any tips, recommendations, or can you see the error? Thanks everyone.

  • Grails/Groovy taglib handling parsing dynamically inserted tags.

    - by Dan Guy
    Is there a way to have a custom taglib operate on data loaded in a .gsp file such that it picks up any tags embedded in the data stored in the database. For instance, let's say I'm doing: <g:each in="${activities}"> <li>${it.payload}</li> </g:each> And inside the payload, which is coming from the database, is text like "Person a did event <company:event id="15124124">Event Description</company:event>" Can you have a taglib that handles company:event tags on the fly?

  • Handling xml files with different structures and different names

    - by zachary
    I have a method and I want different users to pass me xml files. These files will have different names for the elements I am looking for and the elements I am looking for maybe at different structures. My first impression was that we should just tell them to pass in the xml in a standard format. However this is how they have their data and they insist that it is much easier if they don't have to convert it. What can I do to take in data of all types? Have them pass in a dictionary? number = mydata/numbers What is the easiest way for them to define their data to me without actually changing it? sample1 <numbers> 15 </numbers> sample2 <mydata> <mynumbers> 15 </mynumbers> </mydata>

  • How to get full callstack of FaultException

    - by Yosi Cohen
    Hi, I have a WCF service that throws an exception. I get a FaultException in the client without an InnerException. I only have part of the callstack of the original exception, from which it's hard to understand what caused this. How do I get the original exception or at least all the callstack? Thanks.

  • try/catch: errors or exceptions?

    - by Josh
    OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

  • Getting Line Numbers for Errors Thrown in SQL Server CLR Runtime

    - by fetucine53
    Hi all, I've created a CLR stored procedure that I'm running on SQL 2k5 and I'm wondering if there's any way to get line numbers for exceptions thrown by the .NET code. When an Exception is thrown, I get something along the lines of Msg 6522, Level 16, State 1, Procedure myProcedure, Line 0 A .NET Framework error occurred during execution of user-defined routine or aggregate "myProcedure": System.Exception: testing exception System.Exception: at DummyDLL.myProcedure (String dummyInput) . Is there some way I can load the assembly to give me specific line numbers rather than just the function in which the error was thrown? The assembly itself was compiled with a .pdb, but SQL 2k5 doesn't appear to be reading it in when I load the assembly initially. Thanks!

  • Selenium RC: how to capture/handle error?

    - by KenBurnsFan1
    Hi, My test uses Selenium to loop through a CSV list of URLs via an HTTP proxy (working script below). As I watch the script run I can see about 10% of the calls produce "Proxy error: 502" ("Bad_Gateway"); however, the errors are not captured by my catch-all "except Exception" clause -- ie: instead of writing 'error' in the appropriate row of the "output.csv", they get passed to the else clause and produce a short piece of html that starts: "Proxy error: 502 Read from server failed: Unknown error." Also, if I collect all the URLs which returned 502s and re-run the script, they all pass, which leads me to believe that this is a sporadic network path issue. Question: Can the script be made to recognize the the 502 errors, sleep a minute, and then retry the URL instead of moving on to the next URL in the list? The only alternative that I can think of is to apply re.search("Proxy error: 502") after "get_html_source" as a way to catch the bad calls. Then, if the RE matches, put the script to sleep for a minute and then retry 'sel.open(row[0]' on the URL which produced the 502. Any advice would be much appreciated. Thanks! #python 2.6 from selenium import selenium import unittest, time, re, csv, logging class Untitled(unittest.TestCase): def setUp(self): self.verificationErrors = [] self.selenium = selenium("localhost", 4444, "*firefox", "http://baseDomain.com") self.selenium.start() self.selenium.set_timeout("60000") def test_untitled(self): sel = self.selenium spamReader = csv.reader(open('ListOfSubDomains.csv', 'rb')) for row in spamReader: try: sel.open(row[0]) except Exception: ofile = open('output.csv', 'ab') ofile.write("error" + '\n') ofile.close() else: time.sleep(5) html = sel.get_html_source() ofile = open('output.csv', 'ab') ofile.write(html.encode('utf-8') + '\n') ofile.close() def tearDown(self): self.selenium.stop() self.assertEqual([], self.verificationErrors) if __name__ == "__main__": unittest.main()

  • problem with Chrome form handling: input onfocus="this.select()"

    - by binaryorganic
    I'm using the following HTML code to autoselect some text in a form field when a user clicks on the field: input onfocus="this.select()" type="text" value="Search" This works fine in Firefox and Internet Explorer (the purpose being to use the default text to describe the field to the user, but highlight it so that on click they can just start typing), but I'm having trouble getting it to work in Chrome. When I click the form field in Chrome the text is highlighted for just a split second and then the cursor jumps to the end of the default text and the highlighting goes away. Any ideas on how to get this working in Chrome as well?

  • What HTTP error code should I use for unauthorised access to a protected image?

    - by Bala Clark
    I am writing a web application that has secure images uploaded by users. These images are only available to the owner when logged in. I am wondering what the best HTTP error code to throw in the case of unauthorised access? Would a 404 not found, or a 403 unauthorised be better? I am leaning towards the 403, but would it be better to hide the fact that the resource exists to unauthorised users be better?

  • handling NSStream events when using EASession in MonoTouch

    - by scotru
    Does anyone have an example of how to handle read and write NSStream events in Monotouch when working with accessories via EASession? It looks like there isn't a strongly typed delegate for this and I'm having trouble figuring out what selectors I need to handle on the delegates of my InputStream and OutputStream and what I actually need to do with each selector in order to properly fill and empty the buffers belonging to the EASession object. Basically, I'm trying to port Apple's EADemo app to Monotouch right now. Here's the Objective-C source that I think is relevant to this problem: / / asynchronous NSStream handleEvent method - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode { switch (eventCode) { case NSStreamEventNone: break; case NSStreamEventOpenCompleted: break; case NSStreamEventHasBytesAvailable: [self _readData]; break; case NSStreamEventHasSpaceAvailable: [self _writeData]; break; case NSStreamEventErrorOccurred: break; case NSStreamEventEndEncountered: break; default: break; } } / low level write method - write data to the accessory while there is space available and data to write - (void)_writeData { while (([[_session outputStream] hasSpaceAvailable]) && ([_writeData length] > 0)) { NSInteger bytesWritten = [[_session outputStream] write:[_writeData bytes] maxLength:[_writeData length]]; if (bytesWritten == -1) { NSLog(@"write error"); break; } else if (bytesWritten > 0) { [_writeData replaceBytesInRange:NSMakeRange(0, bytesWritten) withBytes:NULL length:0]; } } } // low level read method - read data while there is data and space available in the input buffer - (void)_readData { #define EAD_INPUT_BUFFER_SIZE 128 uint8_t buf[EAD_INPUT_BUFFER_SIZE]; while ([[_session inputStream] hasBytesAvailable]) { NSInteger bytesRead = [[_session inputStream] read:buf maxLength:EAD_INPUT_BUFFER_SIZE]; if (_readData == nil) { _readData = [[NSMutableData alloc] init]; } [_readData appendBytes:(void *)buf length:bytesRead]; //NSLog(@"read %d bytes from input stream", bytesRead); } [[NSNotificationCenter defaultCenter] postNotificationName:EADSessionDataReceivedNotification object:self userInfo:nil]; } I'd also appreciate any architectural recommendations on how to best implement this in monotouch. For example, in the Objective C implementation these functions are not contained in any class--but in Monotouch would it make sense to make them members of my

  • UnauthorizedAccessException cannot resolve Directory.GetFiles failure

    - by Ric Coles
    Hi all, Directory.GetFiles method fails on the first encounter with a folder it has no access rights to. The method throws an UnauthorizedAccessException (which can be caught) but by the time this is done, the method has already failed/terminated. The code I am using is listed below: try { // looks in stated directory and returns the path of all files found getFiles = Directory.GetFiles(@directoryToSearch, filetype, SearchOption.AllDirectories); } catch (UnauthorizedAccessException) { } As far as I am aware, there is no way to check beforehand whether a certain folder has access rights defined. In my example, I'm searching on a disk across a network and when I come across a root access only folder, my program fails. I have searched for a few days now for any sort of resolve, but this problem doesn't seem to be very prevalent on here or Google. I look forward to any suggestions you may have, Regards

  • How to refactor use of the general Exception?

    - by Colin
    Our code catches the general exception everywhere. Usually it writes the error to a log table in the database and shows a MessageBox to the user to say that the operation requested failed. If there is database interaction, the transaction is rolled back. I have introduced a business logic layer and a data access layer to unravel some of the logic. In the data access layer, I have chosen not to catch anything and I also throw ArgumentNullExceptions and ArgumentOutOfRangeExceptions so that the message passed up the stack does not come straight from the database. In the business logic layer I put a try catch. In the catch I rollback the transaction, do the logging and rethrow. In the presentation layer there is another try catch that displays a MessageBox. I am now thinking about catching a DataException and an ArgumentException instead of an Exception where I know the code only accesses a database. Where the code accesses a web service, then I thought I would create my own "WebServiceException", which would be created in the data access layer whenever an HttpException, WebException or SoapException is thrown. So now, generally I will be catching 2 or 3 exceptions where currently I catch just the general Exception, and I think that seems OK to me. Does anyone wrap exceptions up again to carry the message up to the presentation layer? I think I should probably add a try catch to Main() that catches Exception, attempts to log it, displays an "Application has encountered an error" message and exits the application. So, my question is, does anyone see any holes in my plan? Are there any obvious exceptions that I should be catching or do these ones pretty much cover it (other than file access - I think there is only 1 place where we read-write to a config file).

  • warning C6242: A jump out of this try-block forces local unwind

    - by Benjamin
    When we use SEH with __finally block, if we do return in __try block, it causes a local unwind. To Local unwind, the system need to approximately 1000 instructions. The local unwind causes a warning C6242. MSDN suggests using __leave keyword(with saving a return value). But I don't think it's a good idea. If we save a return value and leave the block, there will be many mistakes. Is the waring really necessary? What do you prefer?

  • Handling Incoming Mail to Multiple Recipients in PHP

    - by Navarr
    Alright, this may take a moment or two to explain: I'm working on creating an Email<SMS Bridge (like Teleflip). I have a few set parameters to work in: Dreamhost Webhosting PHP 5 (without PEAR) Postfix What I have right now, is a catch-all email address that forwards the email sent to a shell account. The shell account in turn forwards it to my PHP script. The PHP script reads it, strips a few Email Headers in an effort to make sure it sends properly, then forwards it to the number specified as the recipient. [email protected] of course sends an SMS to +1 (555) 123-4567. This works really well, as I am parsing the To field and grabbing just the email address it is sending to. However, what I realized that I did not account for is multiple recipients. For example, an email sent to both 5551234567 and 1235554567 (using the To line, the CC line, or any combination of those). The way email works of course, is I get two emails received, end up parsing each of them separately, and 5551234567 ends up getting the same message twice. What is the best way to handle this situation, so that each number specified in TO and CC can get one copy of the message. In addition, though I doubt its possible: Is there a way to handle BCC the same way?

  • doubt regarding carrying data in custom events using actionscript

    - by user267530
    Hi I am working on actionscript to generate a SWF dynamically using JSON data coming from an HTTP request. I receive the data on creationComplete and try to generate a tree like structure. I don’t create the whole tree at the same time. I create 2 levels, level 1 and level 2. My goal is to attach custom events on the panels which represent tree nodes. When users click the panels, it dispatches custom events and try to generate the next level. So, it goes like this : On creation complete - get JSON- create top tow levels - click on level 2- create the level 2 and level 3 - click on level 3- create level 3 and 4. …and so on and so on. I am attaching my code with this email. Please take a look at it and if you have any hints on how you would do this if you need to paint a tree having total level number = “n” where( 0 import com.iwobanas.effects.*; import flash.events.MouseEvent; import flash.filters.BitmapFilterQuality; import flash.filters.BitmapFilterType; import flash.filters.GradientGlowFilter; import mx.controls.Alert; private var roundedMask:Sprite; private var panel:NewPanel; public var oldPanelIds:Array = new Array(); public var pages:Array = new Array();//cleanup public var delPages:Array = new Array(); public function DrawPlaybook(pos:Number,title:String,chld:Object):void { panel = new NewPanel(chld); panel.title = title; panel.name=title; panel.width = 100; panel.height = 80; panel.x=pos+5; panel.y=40; // Define a gradient glow. var gradientGlow:GradientGlowFilter = new GradientGlowFilter(); gradientGlow.distance = 0; gradientGlow.angle = 45; gradientGlow.colors = [0xFFFFF0, 0xFFFFFF]; gradientGlow.alphas = [0, 1]; gradientGlow.ratios = [0, 255]; gradientGlow.blurX = 10; gradientGlow.blurY = 10; gradientGlow.strength = 2; gradientGlow.quality = BitmapFilterQuality.HIGH; gradientGlow.type = BitmapFilterType.OUTER; panel.filters =[gradientGlow]; this.rawChildren.addChild(panel); pages.push(panel); panel.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){onClickHandler(e,title,chld)}); this.addEventListener(CustomPageClickEvent.PANEL_CLICKED, function(e:CustomPageClickEvent){onCustomPanelClicked(e,title)}); } public function onClickHandler(e:MouseEvent,title:String,chld:Object):void { //var panel:Panel; for each(var stp1:NewPanel in pages){ if(stp1.title==title){ var eventObj:CustomPageClickEvent = new CustomPageClickEvent("panelClicked"); eventObj.panelClicked = stp1; dispatchEvent(eventObj); } } } private function onCustomPanelClicked(e:CustomPageClickEvent,title:String):void { //cleanup itself Alert.show("onCustomPanelClicked" + title); var panel:NewPanel; for each(var stp:NewPanel in pages){ startAnimation(e,stp); } if(title == e.panelClicked.title){ panel = new NewPanel(null); panel.title = title; panel.name=title; panel.width = 150; panel.height = 80; panel.x=100; panel.y=40; this.rawChildren.addChild(panel); // var slideRight:SlideRight = new SlideRight(); slideRight.target=panel; slideRight.duration=750; slideRight.showTarget=true; slideRight.play(); //draw the steps var jsonData = this.map.getValue(title); var posX:Number = 50; var posY:Number = 175; for each ( var pnl:NewPanel in pages){ pages.pop(); } for each ( var stp1:Object in jsonData.children){ //Alert.show("map step=" + stp.text ); panel = new NewPanel(null); panel.title = stp1.text; panel.name=stp1.id; panel.width = 100; panel.id=stp1.id; panel.height = 80; panel.x = posX; panel.y=posY; posX+=150; var s:String="hi" + stp1.text; panel.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){onChildClick(e,s);}); this.addEventListener(CustomPageClickEvent.PANEL_CLICKED, function(e:CustomPageClickEvent){onCustomPnlClicked(e)}); this.rawChildren.addChild(panel); // Alert.show("map step=" + this.getChildIndex(panel) ); // oldPanelIds.push(panel); pages.push(panel); //this.addEventListener(CustomPageClickEvent.PANEL_CLICKED, //function(e:CustomPageClickEvent){onCustomPanelClicked(e,title)}); var slide:SlideUp = new SlideUp(); slide.target=panel; slide.duration=1500; slide.showTarget=false; slide.play(); } } } public function onChildClick(e:MouseEvent,s:String):void { //var panel:Panel; //Alert.show(e.currentTarget.title); for each(var stp1:NewPanel in pages){ if(stp1.title==e.currentTarget.title){ var eventObj:CustomPageClickEvent = new CustomPageClickEvent("panelClicked"); eventObj.panelClicked = stp1; dispatchEvent(eventObj); } } } private function onCustomPnlClicked(e:CustomPageClickEvent):void { for each ( var pnl:NewPanel in pages){ pages.pop(); } //onCustomPanelClicked(e,e.currentTarget.title); //Alert.show("hi from cstm" + e.panelClicked.title); } private function fadePanel(event:Event,panel:NewPanel):void{ panel.alpha -= .005; if (panel.alpha <= 0){ //Alert.show(panel.title); panel.removeEventListener(Event.ENTER_FRAME, function(e:Event){fadePanel(e,panel);}); }; panel.title=""; } private function startAnimation(event:CustomPageClickEvent,panel:NewPanel):void{ panel.addEventListener(Event.ENTER_FRAME, function(e:Event){fadePanel(e,panel)}); } Thanks in advance.
