 Posted: Mon Nov 13, 2006 8:50 pm Post subject: Unhandled Exception in RxElementFindChild |
|
Hi,
i get an unhandled exception in RxElementFindChild function:
Code: click into code to enlarge
browser = RxFormFindTitle ("Microsoft Internet Explorer", MATCH_SUBSTRING, TRUE, 3000);
if (browser == 0)
{
return FALSE;
}
if (!RxControlGetElement (browser, &elBrowser))
{
return FALSE;
}
if (!RxElementFindChild (&elBrowser, 42, "Adresse", "Edit", &elAddress))
{
return FALSE;
}
I used RanorexSpy to get role, name and classname.
I also tried the DumpElementTree function -> I got the exception in RxElementGetChild function.
What did I wrong / what can I do?
Thanks

Which version do you use? It was a known issue in the version 0.9.3.
(It happened only if a web page had hundreds of elements)
I coundn't reproduce the bug with 0.9.4, i tried it with a lot of web pages.
If you use 0.9.4 then please try the following:
1. The address edit box of the explorer is an edit control, you can find and use it also as follows:
Code: click into code to enlarge
browser = RxFormFindTitle ("Microsoft Internet Explorer", MATCH_SUBSTRING, TRUE, 3000);
if ( browser == 0 )
return FALSE;
HWND addressBox = ::RxFormFindChildClassName(browser, "Edit");
if ( addressBox == 0 )
return FALSE;
// Select the address edit box
::RxMouseClickControl(addressBox);
::RxControlSendKeys(addressBox, "http://www.google.com{ENTER}");
// Wait 3 seconds
::RxSleep(3000);
// Find the explorer control
HWND explorerControl = ::RxFormFindChildClassName(browser, "Internet Explorer_Server");
if ( explorerControl == 0 )
return FALSE;
// Get the element of the IE control
ElementStruct elBrowser;
if (!RxControlGetElement (explorerControl, &elBrowser))
return FALSE;
// Find a child element
ElementStruct elAddress;
if (!RxElementFindChild (&elBrowser, role, name, className, &element))
return FALSE;
...
2. It can be a problem with RxElementFindChild if the browser is not ready with the web page.
3. It can be a bug in RanorexCore, can you save and send us the web page.
It's easier to find the bug if we can debug it.
Please inform us about the results, if it's a bug we would like to fix it for the next release.

Thank you for your reply.
Using HWND addressBox = ::RxFormFindChildClassName(browser, "Edit"); I can find addressbox, but there is still an unexpected exception in DumpElementTree function.
btw:
Actually I want to use a FindElementByValue function, but it does almost the same as DumpElementTree - it stores the first element, if the value is found instead of printing all elements. I get the exception in FindElementByValue and in DumpElementTree.
The elements I want to find are <input type="text" ... value="theValue"> - fields in a web page.
For debugging:
- I am using Ranorex 0.9.4
- the browser is ready with the web page
- it is an easy page (see below)
- the page is stored on local disk
- I am using Visual Studio .NET 2003
- I am using Win XP
Code: click into code to enlarge
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
</head>
<body>
<div id="divID" style="width: 1024px; height: 768px"></div>
<input type="text" name="name1" value="v1">
<input type="text" name="name2" value="v2">
</body>
</html>
Please inform me, if you can find the reason for the exception.
Thanks

I tried to do like this in DumpElementTree function:
Code: click into code to enlarge
...
try
{
if (RxElementGetChild (pElem, index, &child))
{
DumpElementTree (&child, level, pFout);
}
}
catch (...)
{
// do nothing
}
The exception occures in element (pElem):
role = 10
name = ""
class = "Shell DocObject View"
But my element is not found (not printed) although RanorexSpy can find it.

I cannot reproduce this problem.
Here is my code:
Code: click into code to enlarge
#include "stdafx.h"
#include "RanorexCore.h"
#include "stdafx.h"
#include "RanorexCore.h"
void DumpElementTree(ElementStruct* pElement, int level)
{
level++;
int childCount = RxElementGetChildCount(pElement);
for(int index=0;index<childCount;index++)
{
int childId=0;
ElementStruct child;
BOOL ret=RxElementGetChild(pElement, index, &child);
if( ret == TRUE )
{
for(int j=0;j<level;j++)
printf(" ");
printf("Index=%d Name=%s Role=%d Value=%s\n",
index,child.Name,child.Role,RxElementGetValue(&child));
DumpElementTree(&child,level);
}
}
}
BOOL _tmain(int argc, _TCHAR* argv[])
{
// Finding form by class name and activate it (timeout=3000 msec)
HWND browser = RxFormFindTitle("Microsoft Internet Explorer", MATCH_SUBSTRING, TRUE, 3000);
if ( browser == 0 )
return FALSE;
// Find the explorer control
HWND explorerControl = ::RxFormFindChildClassName(browser, "Internet Explorer_Server");
if ( explorerControl == 0 )
return FALSE;
// Get the element of the IE control
ElementStruct elBrowser;
if (!RxControlGetElement (explorerControl, &elBrowser))
return FALSE;
DumpElementTree(&elBrowser, 0);
return TRUE;
}
Please try this code and answer me the resuls, or send me your code.

Now it works - thank you very much!
I tried this:
Code: click into code to enlarge
browser = RxFormFindTitle ("Microsoft Internet Explorer", MATCH_SUBSTRING, TRUE, 3000);
if (browser == 0)
{
return FALSE;
}
if (!RxControlGetElement (browser, &elBrowser))
{
return FALSE;
}
DumpElementTree (&elBrowser, 0);
Your code:
Code: click into code to enlarge
browser = RxFormFindTitle ("Microsoft Internet Explorer", MATCH_SUBSTRING, TRUE, 3000);
if (browser == 0)
{
return FALSE;
}
HWND explorerControl = ::RxFormFindChildClassName(browser, "Internet Explorer_Server");
if (explorerControl == 0)
{
return FALSE;
}
ElementStruct elBrowser;
if (!RxControlGetElement (explorerControl, &elBrowser))
{
return FALSE;
}
DumpElementTree (&elBrowser, 0);
I do not really think this is the reason for the exception, because:
If I use my old code in a new application only with main-function (Ctrl-C, Ctrl-V) it works! But the same code in the other application does not work ...
Thank you once more for your help!

Now I found the reason for the problem:
I started a new thread using AfxBeginThread. The thread function calls another function to find all browser elements.
If I start the thread function directly (not in a new thread) it works!
