I have encountered a problem with wxBusyInfo.
I want to disable user's operation when doing some calculation.
I just write the code like this:
wxWindowDisabler disableAll;
wxBusyInfo info(_T("Working, please wait..."), this);
for(int i = 0; i < 1; i++)
{
Install();
}
In the Install() function, I do some work like this:
wxSleep();
wxExecute(cmd, output, errors);
When I run the application, the busyinfo dialog will show up, but it will no longer at the top of the application. Also after I click the application, or click the busyinfo dialog, it will turn out like the pictures attached. When the Install() function finished, it will be ok. But I don't want users can end the application by that way.
What's the problem? What can I do?
after click the applicatioin
after click the busyinfo dialog
You are calling wxExecute synchronously, which means that it does not return until cmd completes. So you application does not get a chance to update the display.
So, you need to call wxExecute asynchronously.
The snag is that you cannot then see the output and errors from the executed command.

I want to write a script which can detect this message " System is not responding to your request. Kindly try after sometime." as shown in the screenshot below. When this message comes up then I want verify and send mail to the development team.
Snippet which I wrote for verification purpose but it is not working fine for me, pls suggest some alternative:
String s1 = d1.findElementByXPath(".//*[#id='showSearchResultDiv']").getText();
System.out.println(s1);
Remember to be careful when writing code for automation. If the scenario doesn't always show up, you cannot try and find an XPath, because you can't getText() if the object (based on the XPath) doesn't exist first. You probably need a try/catch around your code, and then put the println inside the try. This scenario will occur quite frequently, so you may want to write your own framework on top of WebDriver to handle these use cases.
If that is not the issue. Put a try/catch around the code that is failing to capture what the exception is.
You should try to wait for your element to appear before examining its text:
for (int second = 0;; second++) {
if (second >= 60) fail("timeout");
try { if (d1.findElementByXPath(".//*[#id='showSearchResultDiv']").isDisplayed()) break; } catch (Exception e) {}
Thread.sleep(1000);
}
String s1 = d1.findElementByXPath(".//*[#id='showSearchResultDiv']").getText();
System.out.println(s1);
The exact code may be different, depending on the webpage you're testing (e.g. you should remove the 'fail' line if it's OK for the element not to appear every time.
Stack,
I'm programming an external application that works in Autodesk's Revit (2015). I've created a button on the ribbon that allows the user to place a special equipment that I'll use later to read and pass on to another process. I using 'TheBuildingCoder's' 'Family API' examples to do so. The button on the ribbon has an external command set in the .addin file in the ProgramData Directory...
<AddIn Type="Command">
<Assembly>C:\GSN Programs\MyDll.dll</Assembly>
<AddInId>{97715E4F-EA48-4690-8C62-B5D4836FF452}</AddInId>
<FullClassName>RcarsPlugIn.PlaceEquipment</FullClassName>
<VendorId>MyCompany, LLC</VendorId>
<Text>Place Equipment</Text>
<VisibilityMode>AlwaysVisible</VisibilityMode>
<Discipline>Any</Discipline>
<LanguageType>Unknown</LanguageType>
</AddIn>
On the button press, I put the command data into a global variable to use throughout the program...
If IsNothing(gv_oGo) Then
gv_oGo = New clsGeneralOperations
gv_oGo.CachedCommandData = exCommandData
gv_oGo.UiApp = exCommandData.Application.ActiveUIDocument.Application
End If
With the CommandData cached I move to place the equipment by user pick...
uiDoc = gv_oGo.UiApp.ActiveUIDocument
oSym = oRF.FindElement(doc, GetType(FamilySymbol), "MyEQUIP")
uiDoc.PromptForFamilyInstancePlacement(oSym)
Public Function FindElement(doc As Document, targetType As Type, sTargetName As String) As Element
Return New FilteredElementCollector(doc).OfClass(targetType).FirstOrDefault(Function(e) e.Name.Equals(sTargetName))
End Function
That's where the problem comes into play. I get an error message sent back from Revit stating that "Placement is not permitted in an already modifiable document. The active transaction must be closed first." The problem is, I haven't started a different transaction. The button onthe ribbon is the first that touched when Revit starts.
Is there a way to loop through the open transactions and find one that is open? Is the document in some state that I don't understand? I'm not sure which direction to turn here... any help would be appreciated.
Thanks,
Runnin...
Ok, one clarifying question - the exception is occurring on
uiDoc.PromptForFamilyInstancePlacement(oSym) line correct? if so, try using a subtransaction to complete your command instead:
Document doc = uiDoc.Document;
using (SubTransaction subtr_fam = new SubTransaction(doc))
{
try
{
uiDoc.PromptForFamilyInstancePlacement(oSym);
}
catch(Exception e)
{
Console.WriteLine(e.StackTrace.ToString());
}
}
My application works like this:
Upload Excel file + convert to DataTable
Start new thread
Begin loop through DataTable
Update UI (Label) to show "Processing row [i] of [n]"
Next
End loop
The bold is what I'm not able to do. I've looked around online for updating UI elements from worker threads, but all the results I can seem to find are for Windows Forms, rather than a web project. Is this possible?
yes, you can do it, and actually it is not difficult. you can use ajax toolbox to do it easily. simply use an updatepanel, and update progress.
check http://ajaxcontroltoolkit.codeplex.com/
an example: http://www.asp.net/ajax/documentation/live/overview/updateprogressoverview.aspx
I found a workaround using jQuery AJAX and asp.NET WebMethods and a session variable.
I used a method from one of my previous questions, by having a WebMethod check on a Session variable that was updated by the worker thread.
Worker thread:
Session["progress"] = "{\"current\":" + (i + 1) + ", \"total\":" + dt.Rows.Count + "}"
WebMethod:
[WebMethod]
public static string GetProgress()
if (HttpContext.Current.Session["progress"] == null) {
return "{\"current\":1,\"total\":1}";
} else {
return HttpContext.Current.Session["progress"];
}
}
my jQuery basically looped calling that AJAX WebMethod every second. It would start on page load and if the current = total then it would display "Completed" and clear the loop, otherwise it shows "Processing row [current] of [total]". I even added a jQuery UI Progressbar
This is kind of a manual solution but it solves my problem, with little overhead. An unexpected but nice piece is that since it is utilizing a Session variable, and the WebMethod checks on page load, if the worker thread is active then the progressbar will show even if you navigate away and come back to the page.
I have a form with a listview in it that the user can add tasks too. Then the user can click a button then the application goes through each task in the listview 1 by 1 an executes it.
These tasks are more like instructions that actually complete tasks.I do this by having a class with a loop in it that goes through each item and it then completes a task I set for each item(instruction). In order to start the parsing I have a button on a form that calls that function. IE: RunTask(listview1, 1) - basically all this does it starts the loop I have in my class , with a specified listview and which item to start on.
Everything works perfect except the screen locks up, so I cannot implement a stop feature to stop the application from parsing these listview items. I just don't understand how I can implement this without crossthreading, since the thread that I would like to run seperate will always access this listview. It is not feasable to redesign the program to get rid of the listview. I tried application.doevents although it caused way too man bugs. I have been researching for days on how to fix this but I have NO idea. Hopefully someone cans hed some light.
Also I had already added a background worker to solve the issue, although I had to obviously set checkforillegalcrossthreadcalls = false and I know this isn't smart.
Try doing something like this. Take you list view and turn it into a set of values that aren't UI related. Like this:
string[] values =
this
.listView1
.Items
.Cast<ListViewItem>()
.Select(x => x.Text)
.ToArray();
Then you can use the parallel task library to run your task in the background:
var tokenSource = new System.Threading.CancellationTokenSource();
var token = tokenSource.Token;
var task = System.Threading.Tasks.Task.Factory
.StartNew(() => RunTasks(values, 1), token);
If you need to cancel the task you can do this:
tokenSource.Cancel();
But to handle UI updates when the task is finished do this:
task.ContinueWith(r =>
{
/* When compete code */
});
Make sure that you invoke the UI updates so that they go on the UI thread.
My apologies that I didn't write this in VB.NET. My VB is getting rusty.
Ive got an problem currently on an mobile site that i'm running directly in my pc's firefox browser. Everytime a button is clicked, the page reloads, thus resetting my variables. I've got this script:
// ==UserScript==
// #name trada.net autoclick 55_1min_mobile
// #namespace airtimeauction auto click
// #include http://www.trada.net/Mobile/
// #version 0.1
// #description Automatically click // ==/UserScript==
var interval = 57000;
var bidClickTimer = setInterval (function() {BidClick (); }, interval);
var numBidClicks = 0;
function BidClick ()
{var bidBtn1=document.getElementById("ctl00_mainContentPlaceholder_AirtimeAuctionItem7_btn_bidNow");
numBidClicks++;
if (numBidClicks > 500)
{
clearInterval (bidClickTimer);
bidClickTimer = "";
}
else
{
bidBtn1.click (1);
}
};
BidClick();
It should click the button every 57 seconds, but the moment it clicks the button, the page reloads, thus resetting the variables. How can i get greasemonkey to "remember" or carry over the variables to the next page/script when it reloads? Will it have something to do with GM_setValue? It will only be this few variables, but the second problem or question wil be, will it subtract the few seconds it takes the page to reload from the "57" seconds? How do i compensate for that?
In addition to GM_setValue...
you also can use the new Javascript "localStorage" object, or a SQL Javascript API.
The advantage of the SQL approach is it is very meager in its resource consumption in a script (think about it; rather than concatenating a humongous string of results, you can tuck away each result and recall it if needed with a precise query. The downside is you have to set up a SQL server, but using something like SQLite that's not a big deal these days. Even postgres or mysql can be quickly spun on a laptop...
Yes, I think you have to use GM_setValue/GM_getValue.
And if you have to do something exactly every 57 seconds, then calculate the time when the next action should take place after the reload, and store it using GM_setValue.
When your script starts, read first if the next action is stored, if it is, use that time to schedule the next action, and calculate the time for the action after that, and so on...
GM.setValue will set a value indefinitely and is scoped to the script, but will work if your script runs across multiple domains.
window.localStorage will set a value indefinitely and is scoped to the domain of the page, so will not work across domains, but will work if you need several GreaseMonkey scripts to access the same value.
window.sessionStorage will set a value only while the window or tab is open and is scoped to only that window or tab for that domain.
document.cookie can set a value indefinitely or only while the browser is open, and can be scoped across subdomains, or a single domain, or a path, or a single page.
Those are the main client-side mechanisms for storing values across page loads that are intended for this purpose. However, there is another method which is sometimes possible (if the page itself is not using it), and can also be quite useful; window.name.
window.name is scoped to the window or tab, but will work across domains too. If you need to store several values, then they can be put into an object and you can store the object's JSON string. E.g. window.name = JSON.stringify(obj)
