Because of reasons, I have a situation in which I need to use a .js file to call a .bat file, which calls a .ps1 file. It may sound crazy, but yes, I have to launch the .ps1 file this way.
My problem is that, the .js file is hanging after writing a variable number of errors. The number of errors that causes the script to hang changes between scripts, but seems to be consistent within a script.
I have included sanitized scripts below.
Every time I run this particular combo using cscript (cscript c:\temp\test.js "c:\temp\test3.bat"), the script stops after writing "Checking device 10 of 100." to the log file and does not return me to the prompt. If I run the .bat file from the same command prompt, the script runs as expected. If, on line 41 of the .ps1 script, I change the message type from "Error" to "Verbose" (for example), the script runs fine and completes as expected.
It seems that the .js file does not like something about "Write-Error $Message" from the Out-PsLogging function but:
I cannot tell what it doesn't like
I cannot tell why it stops writing errors after (in this case) 10 errors
I have seen this behavior on Windows 10 and Server 2019 (ps 5.1).

if (!wshShell) {
WScript.Echo("Can not run command");
}

try {
oExec = wshShell.Exec(cmdLine);
WScript.Echo("Ran the command - " + cmdLine);
WScript.Echo(oExec.Status);

Turns out the issue is a bug in wscript: https://groups.google.com/forum/#!topic/microsoft.public.scripting.wsh/kIvQsqxSkSk

Says the url is wrong but it seems right to me.
I'm trying to download a file from the internet launch the program, then after the process ends to delete the program.
Any help would be great
process will be
start exe ---> to create the simple downloader ---> add parameters via bat file ---> launch the file -----> wait for the process to end -----> delete the files downloaded.
I have yet to add the wait process and delete commands

I've been working on a web interface for iPerf and it's going pretty well. My goal is to have the output of the commands be streamed live on the page. It works for iPerf2 commands but when I run iPerf3, it only shows the output once the entire test is complete.
Based on my research I've done on this site and others, I'm thinking it might have something to do with the buffer. I've been messing around with flushing the buffer at different times or setting the 'fread' length to different values but I can't get it to act the same as regular iperf commands. I think this because instead of running the 'popen' on the iperf command itself, I used popen on a python script that would run the iperf command. This still returned the same issue. It only shows the output on the web page once the entire test is complete.
Here is my code:
phpQ.php
<!DOCTYPE html>
<html>
<body>
<div>
Server Domain/IP Address: <input id="address" type="text"><br>
<input id="run" type="button" value="iPerf"><br><br>
</div>
<div id="result"></div>
<script>
function updateText(address) {
var ajax = new XMLHttpRequest();
ajax.onreadystatechange = function() {
if (this.readyState == 3) {
var old_value = document.getElementById("result").innerHTML;
document.getElementById("result").innerHTML = this.responseText;
}
};
if (purpose == 1) {
var url = 'ajaxQ.php?address='+address;
ajax.open('GET', url,true);
ajax.send();
}
}
document.getElementById("run").onclick = function(){
address = document.getElementById("address").value;
purpose = 1;
updateText(address);
}
</script>
</body>
</html>
ajaxQ.php - to see the difference, change "iperf -c" to "iperf3 -c" in the $iperfCmd variable.
<?php
function liveExecuteCommand($cmd,$address)
{
while (# ob_end_flush()); // end all output buffers if any
// tells the user what command is going to run
echo "<pre>Running Command: '".$cmd."'</pre>";
// open the command to run and read output
$proc = popen("$cmd", 'r');
$live_output = "";
$complete_output = "";
while (!feof($proc))
{
# flush();
$live_output = fread($proc,4096);
// adds the live output to the complete output
$complete_output = $complete_output . $live_output;
// prints the live output
echo "<pre>$live_output</pre>";
}
sleep(1);
// close the process
pclose($proc);
echo "<pre>------------------------------------------------------------\nAll Done!</pre>";
}
// this happens if the iPerf button is pressed
if (isset($_GET['address'])) {
$address = $_GET['address'];
$iperfCmd = "iperf -c ".$address." -i 1 -t 5";
liveExecuteCommand($iperfCmd,$address);
}
else{
echo "No post request";
}
?>
FYI, I am running the iperf client on an 'Ubuntu 16.04.2 LTS' CLI server and the iperf server on an 'Ubuntu 16.04 LTS' desktop server.
Thanks for any help!
I have written the below code in my js file in chrome extension.
var xhr_put = new XMLHttpRequest();
xhr_put.open('PUT',"https://something/index.php",true);
xhr_put.onreadystatechange = function()
{
console.log('File Cleared',"Yes");
}
And the below code in my PHP file.
$requestmethod = 'PUT';
if ($_REQUEST['REQUEST_METHOD'] === $requestmethod)
{
$f = #fopen("facebookmsg.txt", "w");
print "in here";
if ($f !== false) {
ftruncate($f, 0);
fclose($f);
echo "here";
}
}
But my file on server is not getting empty. I need help as to what is wrong and how do i correct it?
I am using qzprint API for printing labels in my open cart extension. Everything was working fine but suddenly it stopped working on FF. In Internet explorer it works fine. If i add alerts in my functions of applet it works fine on firefox as well but not sure why not with out alerts. here is my code.
calling applet functions in my header.tpl

As u can see in my deployqz() and usedefaultprinter() functions i have alert on first line which is in comments if its commented it doesn't work in fire fox and if not commented than it works fine. With comments i get alert message from isLoaded() function "Print plugin is NOT loaded properly!".
Also in my console i get this
An unbalanced tree was written using document.write() causing data from the network to be reparsed. For more information https://developer.mozilla.org/en/Optimizing_Your_Pages_for_Speculative_Parsing
Try this:
If the qzReady is called by the applet when ready, put useDefaultPrinter inside that function.
if isLoaded takes some time, call useDefaultPrinter in there too using setTimeout
Like this
<script type="text/javascript">
deployQZ('<?php echo HTTP_CATALOG ?>');

I'm trying to use phantomJS to capture a screenshot of a URL, however when I call phantomJS (from either the command line or web app) it hangs and seesm to never execute the "exit()" call. I can't seem to find any error messages and it remains running until I kill it. This is the JS file that is passed to the phantomjs command:
var page = require('webpage').create();
var system = require('system');
var script_address = '';
var page_to_load = '';
var members_id = '';
var activities_id = '';
var folder_path = '';
if (system.args.length < 5)
{
console.log('Usage: phantom_activity_fax.js script_address page_to_load members_id activities_id folder_path');
console.log('#Args: '+system.args.length);
phantom.exit();
}//END IF SYSTEM.ARGS.LENGTH === 1
//ASSIGN OUR ARGUMENTS RECIEVED
script_address = system.args[0];
page_to_load = system.args[1];
members_id = system.args[2];
activities_id = system.args[3];
folder_path = system.args[4];
console.log(system.args[0]);
console.log(system.args[1]);
console.log(system.args[2]);
console.log(system.args[3]);
console.log(system.args[4]);
//OPEN OUR PAGE WITH THE VALUES PROVIDED
page.open(page_to_load, function () {
console.log("Entering Anonymous Function, Beginning RENDER:\n");
page.render(folder_path+members_id+'_'+activities_id+'.png');
phantom.exit();
});
I see the values pushed to the console, but after that it just hangs :( I've tried the web inspector, but could not understand where to execute the __run() call, and didn't see any change when I added the debugger-autorun=yes to the call :(.
This is the output I get from the command line when it hangs (as root user):

(The page it tells PhantomJS to "scrape" is a simple PHP script that outtputs a print_r() of $_SESSION and $_REQUEST)
If something goes wrong in your script (such as in page.render), phantom.exit() will never be called. That's why phantomJs seems to hang.
Maybe there is an issue in page.render but I don't think so. The most common causes of hangs are unhandled exception.
I will suggest you 4 things to investigate the issue :
add an handler to phantom.onError and/or to page.onError
encapsulate your code in try/catch blocks (such as for page.render)
Once the page is loaded, there is no test on callback status. It's better to check the status
seems to freeze when calling page.render. Have you tried a simpler filename in the current directory ? Maybe the freeze is because of the security or invalid filename (invalid characters ?)
Hope this will help you
Use :
$phantomjs --debug=true rasterize.js http://... test.pdf
In rasterize.js add a timeout on ressource, that was my problem:
