I have 1 form and datagridview in it. When I click update button,new forms open with progressbar only. In that form I have 2 functions. 1 for connecting email and downloading excel file. The other for reading excel file and updating my database. It is working fine. Now , I want that when I close the progress bar form , it should be cancelled. I tried backgroundworker and creating thread but I couldn't make them work for my purpose. Can anyone help me?
How about using a cancellation token in a task?

I am beginner in using Visual FoxPro. I am trying to create a simple application which contains a form with a few textboxes. The problem is that the application window does not appear when I run the executable file which I build.
The code for the program is:
PROCEDURE main_app
_SCREEN.Activate
_SCREEN.WindowState = 2
_SCREEN.backcolor = RGB(128, 128, ;
128)
_SCREEN.Caption = ""
_SCREEN.refresh()
SET TALK OFF
SET DELETED ON
SET EXCLUSIVE OFF
CLEAR ALL
CLEAR
CLOSE ALL
DO FORM simpleform LINKED
READ EVENTS
RETURN
*MESSAGEBOX('Msg')
ENDPROC
In the form I have a few textboxes and a button. When the button is clicked then some code is executed. If I run the application from the IDE everything works fine but if I create the executable this does not display any window, still the process appears in the task manager. If I uncomment the MessageBox then this will appear even if I run the exe file. I don't know a way to trace the problem outside the IDE, maybe there is still a library needed that I am not aware.
I am using Visual FoxPro 9.0
Would someone be able to help me out?
If you can provide me with a link to a very simple application exe which uses just one form and finishes when the form is closed I would very much appreciate it.
Thanks in advance
I tried creating a brand new project, new code and new form just as you described. I copied your code and ran, but it never displayed the form.
If this is the main app in your project, you don't need the initial
PROCEDURE main_app
just remove this line as there is nothing CALLING the "Main_App" and thus is never getting called to ultimately call your form.
Just comment it out, save your project and run it... See what you get, it SHOULD work.
** PROCEDURE main_app
The problem was that I did not set the screen visibility to true.
I want a solution for the following scenario:
In a page I am uploading an xml and while clicking on the upload button I am going to recieve an pop up for confirmation (I am able to detect this), after this again I am recieving an pop up which I am not able to detect (The page is still getting loaded in the browser ). Kindly help me to sort this out .
I have tried with many solutions for this like: get window ids,titles .
Thanks
You can you use -
$sel->get_confirmation()
This retrieves the message of a JavaScript confirmation dialog generated duringthe previous action. By default, the confirm function will return true, having the same effectas manually clicking OK. This can be changed by prior execution of thechooseCancelOnNextConfirmation command. If an confirmation is generatedbut you do not get/verify it, the next Selenium action will fail.
NOTE: under Selenium, JavaScript confirmations will NOT pop up a visibledialog.
NOTE: Selenium does NOT support JavaScript confirmations that aregenerated in a page's onload() event handler. In this case a visibledialog WILL be generated and Selenium will hang until you manually clickOK.
Returns the message of the most recent JavaScript confirmation dialog.
You should always refer to WWW::Selenium - Perl Client while working with perl and RC.
I have found what is the problem #amey ...I am tring to upload an file which is not actually not permitted due to some security issues with firefox... There was actually an work around for this
http://cakebaker.42dh.com/2006/03/29/file-upload-with-selenium/
.....Which will not work with latest Selenium RC with Firefox since firefox have removed the support for enablePrivilege

Thanks for your support....
my solution was using the function:
$driver->execute_script("Events.invokeEvent('UserDetailPage:UserDetailScreen:UserDetailToolbarButtonSet:UserDetailToolbarButtons_DeleteUserButton_act', true);");
analyzing what the javascript code does when the Accept button was pressed. and executing that code in the function.
I'm hopefully missing something obvious here...
I have just kicked off developing a new Access 2010 application. Something personal and hopefully simple.
The first thing I need to do is read a bunch of files off of the hard drive. I parse the contents adding the information to a table if it doesn't already exist.
Code works fine, that's not the issue. As it can take a while I've added a simple progress dialog using a standard form but in dialog/popup mode. As the For Each loop of the FSO.Folder.Files object is progressed I send some information to a couple of text boxes and issue a Me.Repaint (have also tried DoCmd.RepaintObject acForm, "FormName").
The issue is that I can get anywhere from 5% to 35% of the process complete before the repaints stop responding. The form only repaints when it gets to 100%.
The process uses limited recursion - if there is a subfolder - it calls itself to process that subfolder, but the folder structure is fairly linear so not many of those.
There are nothing bound to the form. All table updates happen in code and via RecordSets.
Any ideas why Access stops responding?
Cheers,
Roy
Add DoEvents after Repaint. That will cause Access to yield to Windows, which will can then handle its pending tasks ... such as updating the display in this case.
Actually, if your code updates text boxes, I don't see why you need to Repaint the form in order to display the changes. Try something like this instead ...
Me.MyTextBox = "hello"
DoEvents
I have a report that is taking about 10 minutes to load when opened through the application, but only 2 seconds when opened through VS 2008. There are many other reports which all work fine and I don't know what could be different about this one.
In the application, all of the code to load and setup the report runs fine but when I launch the form that has the viewer on it it displays the form, but hangs for several minutes before the report comes up. It's clear that it's not the query itself that is the problem since it only takes a second to run in VS, and all that is on the form is just the viewer.
After setting up my report into a variable named rDoc, I run the following code:
CrystalReportViewerForm frm = new CrystalReportViewerForm();
frm.CrystalReportViewer.ReportSource = rDoc;
Application.Run(frm);
CrystalReportViewerForm has the viewer control on it, and a public property called CrystalReportViewer that exposes the viewer so the calling code can set the ReportSource before opening the form, as you can see in the code. That is literally all the form consists of. When Application.Run(frm); is run it shows the form and viewer, but the report doesn't load for about 10 minutes.
If anyone else has run into this and solved it please let me know what you did!!
Thanks!
I'll go ahead and post the way I fixed it here in case it helps anyone, but I'd still like to hear if anyone else knows what the problem actually is...
My report was using the built in features of CR to select tables with data expert. I got rid of all the tables and added a command with the sql needed to get the data. This solution would obviously be faster because it doesn't return as much data and the processing is all done in SQL. However, it worked fine the way it was when run through VS so I know that's not the whole of the problem. At least it works now though.
I have an MS Access 2003 database that I'm using to develop a basic little inventory app. I have added some extraneous forms along the way and I wanted to get them out of the DB. I deleted most of them just fine but one of them appears to have left behind its VBA Object. All that's in the object is Option Compare Database. Now whenever I try to work with the database, I get the following error:
The form name 'Transaction1' is misspelled or refers to a form that doesn't exist.
If the invalid form name is a macro, ...
Truncated for typings sake.
Yes, I agree, the form doesn't exist. What confuses me so much is that all of the other forms, when I deleted them, also destroyed their VBA object as well. This one, no matter what, seems to like to stick around and I have no idea how to get rid of it.
How do I get rid of it?
Things I've tried:
Compact and Repair and the DB
Create a new form named what it's expecting, verify that it gets rid of the problem, and then delete that form.
You can try the /decompile switch
Make a backup of your mdb
Open your mdb (hold the SHIFT key down to stop any code from running) via a short
cut: msaccess.exe database.mdb /decompile
Open a module and compile your app
Save and close Access
Open again (SHIFT again) without decompile
Compact and repair database
close Access
I had similar problem. I found I had named the missing form in the STARTUP menu as the default form to open when starting Access. I opened Tools>Startup and deleted the missing forms name from the "Display/Form/Page" field of the Startup. My problem solved.
The problem I was having is that the form was named ~TMPCLP8151 and would not show up in Access no matter what I tried, but I could see it in VBA in the Project Explorer. Here's how I resolved the issue. I created a new form, and created an Event Procedure for Form_Open that contained this:
DoCmd.DeleteObject acForm, "~TMPCLP8151"
Then I just opened the form, and sure enough, the VB code deleted the form that I could not delete myself.
I had a same problem. I created a form with same name and deleted the form again. That fixed the peoblem. Try. BTW try to open the new form in design mode to make sure if the VBA module is assosiated with the new form.
I had to combine both solutions to achieve the goal.
First de- and recompile
next compact and repair
then create new form with the same name and delete it
Pay attention that the form has the status Hasmodule set to Yes
I had this problem. I renamed my default form from Form Login to frmLogin which suits my naming style, but the program was still looking for it on opening. I am using 2013 so I went to File » Options » CurrentDB and in the display dropdown select the new name. The old name remains in the list until you close and restart the application.
