FabFly Posted January 6, 2006 Author Share Posted January 6, 2006 Hi all,@DaleI've included your FuncErr() in my script.That's is the result:We intercepted a COM Error!Number is: 00000000Windescription is: 1.53564711381288e-038scriptline is: 0$IE_BO5UK is object: 1$IE_BO5UK object type: IWebBrowser2$IE_BO5UK.document is object: 1$IE_BO5UK.document object type: DispHTMLDocumentI don't understand what does it mean :"> What can I do I I don't call _IELoadWiat directly in my script? Is there another issue?@CameronWhen I said that I launched the scripts on the night it's because I'm french and when you're reply it's time for me to leave my office :-Dthanks all Link to comment Share on other sites More sharing options...

Fur Posted January 6, 2006 Share Posted January 6, 2006 I think I'm the other user Dale was referring to.. It was happening to me on my laptop which has a ton of mapped network drives at the office, while I was connected at a hotel where those drives obviously were not present. If you don't know, Windows gets very fussy in this situation if you don't go in and unmap all the drives. I'll have to try to recreate this again.

DaleHohm Posted January 6, 2006 Share Posted January 6, 2006 @Dale I've included your FuncErr() in my script.We intercepted a COM Error! Number is: 00000000 Windescription is: 1.53564711381288e-038 scriptline is: 0 $IE_BO5UK is object: 1 $IE_BO5UK object type: IWebBrowser2 $IE_BO5UK.document is object: 1 $IE_BO5UK.document object type: DispHTMLDocument Ugggh. This isn't helpful. Number should be an error number and Windescription should be a text description of it. Please carefully examine how you are entered the error trapping code to insure there were no problems with it, I would also appreciate if you would simulate an error with something like $IE_BO5UK.bogus to see if the trap is working properly and gives valid returns then. Also, I know I told you to use the equiv of $oIE in the error function, but please change it to $o_object to see if we can get the state of the local function variable. One other thing that would help is if you can isolate exactly what statements lead to this error... you may need to pepper you code with ConsoleWrite commands to show where you are (or use the Trace Lines function in SciTe).

footswitch Posted January 6, 2006 Share Posted January 6, 2006 eeeerrrmmm... Hi Dale, you might remember me from my reply to "Internet Explorer Automation UDF library". Well, while I was trying to isolate a piece of code... It happens that no errors occurred. Then I came back to my original script and... no erros occurred. Tried OVER 300 times. Really. No errors. I can't figure out how to generate these errors. Maybe these objects suffer minor or temporary changes or maybe the way the function accesses and handles them can't assure a flawless operation... But that's something I can't have a clue, because I really don't know anything about the way Internet Explorer works... Is there anything I can help? Any other script to test, or whatever... Good luck you all, I'll keep testing my scripts and ideas... Link to comment Share on other sites More sharing options...

I created a script to manually reboot my router when my internet connection jams (this happens about 3 to 4 times a day). Until someday I got home and my little home "server" had this error msgbox. Tried out a couple of times and... tada! all my scripts would eventually cause this error. The question is... how and why? ...

DaleHohm Posted January 6, 2006 Share Posted January 6, 2006 I have three theories about what is happening here: 1) User error/bad code. The opject bing passed to _IELoadWait is incorrect and is caused by a code logic problem 2) An unexpected action occurs on the web server or client browser that affects the object passed to _IELoadWait and makes it invalid (a page redirect for example) 3) There is some sort of timing issue or race condition that is only seen when the conditions are just right (or wrong) that causes the object to be in some unexpected state during a brief transition time. 1 and 2 are more mundane and if either is the cause, the person having the trouble should be able to construct a reproducer once the mechanics are understood. 3 is more difficult, but not impossible to overcome if it turns out to be the case. I simply don't want to put the work into 3 or complicate the UDF code unnecessarily if it turns out that there really is no issue there. So again, please help to create a reproducer or work to rule out 1 and 2 and then we'll focus some effort on 3.

Combining a beta autoit with a "beta" script... it's just not stable enough, because faults CAN happen. And luckily we saw that happening. If people in general wouldn't care about exceptions and just script superficially, most programs would be a piece of... bad coding Sorry, i assumed since you were trying to duplicate the error based on KNOWN error conditions. If you don't know what the error conditions are, as far as what values are generating errors where, then my suggestion would be to setup a dump. Have your script write values that it's working with to a file as they're assigned, have a _FileWriteLog() with the function name every time a function is entered or exited also. When the script is finished successfully, you could delete the log to avoid excess log size. In the event that an error occurs, you'll have the dump file to see what values were where and which function was the last entered but not exited since the file won't be deleted on a failed attempt that doesn't reach the FileDelete(). Just because i wouldn't waste time actively monitoring (or having another person do it) a program that i consider done enough to be called a beta does not mean that i don't care about exceptions or that i employ superficial coding practices. If i were doing anything manually 300 times on a computer, even if it is something as simple as executing a script, i would consider it a horrible waste of time. But that's just me.so... let's try to solve this? solve what exactly? the code you didn't include, the error you can't produce, or the error conditions that you don't know?

footswitch Posted January 6, 2006 Share Posted January 6, 2006 (edited) Look cameronsdad, I'm not really into being against you. I'm just assuming this error never happened with you. Maybe you don't write scripts in which you need IE interaction. Maybe you never needed to automate an IE process. But for those who do, the solution could come in handy. We're talking about an error that no one knows how to specifically reproduce. I think everyone, including you, acknowledges that. Lol maybe I didn't include any piece of code because it does NOT generate errors everytime it is executed, so... technically it doesn't help (edit) Oh... by the way... those 300 tries were done with the help of a stand-alone loop script with random sleep time involved Best regards EDIT: typos, details Edited January 6, 2006 by footswitch Link to comment Share on other sites More sharing options...

Are you receiving the same error as the OP of this thread? Do you have a screenshot of the error? The dump file that i suggested in my previous post really is a good way to go when you are unsure of the error conditions bringing about an exception, because it allows you to re-create the error more consistently if you know exactly what values are being passed to what function when it fails. Dale's error trapping is kind of the same way, except it's a more centralized approach, with all of the error trapping being handled at one spot. Which is good when you've some idea what is causing the error, or when it is occuring in the code. my way is a little more involved, but it should give you enough information to consistently re-create any error you receive, eliminating alot of time wasted with trial and error. As far as automating IE, yes i've had some experience with it, and i typically recommend use of dale's IE.au3 5-10 times a day to people trying to work with webpages or web based data. Not saying that as a 'haha you were wrong' just letting you know that i have infact used it, including troubleshooting errors. Link to comment Share on other sites More sharing options...
footswitch Posted January 6, 2006 Share Posted January 6, 2006 (edited) eeerrrmm.... lol...I'm feeling dumb enough... Below you can find a script to reproduce the error. It's kinda stupid, but leave it running long enough (or short enough, nobody knows when it will happen )NOTE: Press "c" anytime to exit the script before it fails (lol again)...The screenshot of the error is in the first post of this topic by FabFly.#include<IE.au3> HotKeySet("c","cancel") While 1 $new_window=_IECreate(1); 1 is visible, 0 is invisible _IENavigate($new_window,"http://www.google.com",1); 1 is wait for loading to complete =) _IEQuit($new_window) WEnd Func cancel() Exit EndFuncSo... how exactly would we place a nice debugger here? any help? of course we could also change the IE.au3 file and add the debugger there, right?EDIT: hey, cameronsdad, I'm a peaceful guy. Please remember that english is not everyone's native language, so sometimes the writing and interpretation between all of us is somehow messy thanks for your help, really EDIT2: to force the error, type a "slow" webpage in the _IENavigate() function and close the Internet Explorer window BEFORE it loads completely.

Also edited my previous post.actually, the $new_window is just part of the variable name being used in my example, it also appends a random number to the end of the variable name, preventing re-use of the same name. One thing that could be done to avoid the memory usage would be: #include<IE.au3> HotKeySet("c","cancel") While 1 $blah = "$new_window" & Random(1,1000000,1);stores string value of new variable name Assign($blah,_IECreate(1)); assigns new object to the variable named in the string held by $blah _IENavigate(Eval($blah),"http://www.google.com",1) _IEQuit($new_window) Assign($blah,"") WEnd Func cancel() Exit EndFuncthat is untested code, but it should work. As far as your edit to the other post, any time you close the browser, then try to access a reference to it after the fact, you're going to get an error, because you're invalidating the references to the browser. The only way you're going to avoid that, is to validate that the reference is still good before trying to access any properties of it. Link to comment Share on other sites More sharing options...

rpilkey Posted January 7, 2006 Share Posted January 7, 2006 I used to get this a lot too, it went away when I uninstalled the google toolbar. I don't have any evidence or reason why that would affect it, but that fixed it for me. Maybe it interferes with the object hierarchy somehow?
