Right now in my app I have a Pause and a Continue button, basically I enable/disable the controls on the form. Is there a better way to handle this.
Is there a way to lock the cursor in the control that it is in when the Pause button is clicked and then release it when the Continue botton is clicked?
Dim d As Integer
For d = 0 To TextBox2.Text
WebBrowser1.Navigate(TextBox1.Text)
//a code that pauses the loop but does not stop the browser thread
I am creating a small applicaiton for simulating dice roll. To simulate bounces I change the position of the picture randomly. Now to simulate more than one bounce, I used a for loop to continuously change the position of the picture box. But it is not happening as I planned, the form only displays the position of the last loop. I even tried using System.Threading.Thread.Sleep(1000) hoping to show the bounces, but even they show the last loop only.
For bounceCount As Integer = 1 To bounces
bounce(pb_dice1)
bounce(pb_dice2)
System.Threading.Thread.Sleep(3000) 'I need to pause here and show the recent change in position then continue after 3 seconds
Next
the bounce method changes the position of the PictureBox.
How can I pause my for loop, display the newly positioned dices, and then continue after 3 seconds?
I am fairly new to programming and vb.net and I am working on a small project but in the project i need a message box (2 different occasions) where the buttons, instead of Yes No say Pause and GO. The video [URL] told me to make a new form (dialogue) and then in my main form add a public sub.
Here is the sub I have:
Public Sub injectmessage(ByVal ingmessage As String)
Dim topmessage As New Message
Dialog1.Label1.Text = ingmessage
Dialog1.ShowDialog()
End Sub
All that does is puts the message on the messagebox.
I loaded up VS 2010 to work on a VB.NET project but for some reason the Run/Pause/Stop buttons are missing from the toolbar and I cannot set breakpoints. Only changes from yesterday to my system was this morning Windows was trying to install Visual Studio SP1 updates but all failed.

I am actually designing a simple media player. Here are all the buttons I have
1)play
2)pause
3)stop

8)repeat playlist

WMP.uiMode = "NONE"

In all of these only play, stop and pause work everything else isn't working. tried lot of codes and even forms nothing works ..
1) Why the pause button and also the pause command does not exist in VB 2010 Express?
2) I have some solutions under 2010. In 2 or 3, while debugging, I can change instructions without restarting the application. In others, I cannot change anything (Is like readonly), Looking in 'My Applications', Tab 'Debug', Option 'Configuration' I can choose several Options. In the applications I can debug, the default is 'Active (Debug)'; in the others is 'Active (Release)'. If I change the options, the word 'Active' remains attached to the original option.
i need to get some buttons to interact with other buttons on screen when i click then, as each indivual button gives a slightly different result.imagine this:[code]....
then i need then to hide different buttons depending on which button was pressed. so say i pressed button 1 then all the buttons showed but alternativly if i had of pressed 2 then say button 5 and 6 disapear.managed to get one way to work but then i would only ever end up with the first results every time.
I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.

View 4 RepliesWhen I do the try/catch method in my vb.net project I will try the code I want and when it can't do it, i make a message box right after the catch method. The thing is that it will show the message box, and then another message from the program itself. Like for example, I have here a MySQLException, and when i click ok on the message box, it will show another one right after showing the exception itself. How would I be able to get rid of this so the user doesn't have to see this, and the program can continue.
View 2 RepliesI was thinking I could make a console application that would have a FileSystemWatcher - watching for a .BAT file being created in a folder - and when it sees that file it does a PROCESS.START on it. But I'm seeing that a console app doesn't continue running.

Module awcWatcher

I was observing my programs process in the task manager and noticed each action made to the program made the memory continue to rise. So I added a Garbage Collector and since it's my first time using it im not sure if I implemented it right. I haven't gotten any errors but I ran some tests I would like to go over with everyone. After adding the GC I was able to notice a change in the memory my program used- it was reduced.I added the GC to the main forms formClosed event of my application which is used in different scenarios. I also added it to the panels paint events before I tested the program. And noticed a quicker reduction in memory. The Form i mainly use called frmLine1t5. This form calls to the database based on which line to test. Then the form sets the controls that were added in design view to be enabled or disabled based upon the product for that line. This process was easy to implement.I Load each new frmLine1t5 to a collection of the form so people can run multiple tests using the same form. This helped so i didn't have multiple forms for the same type of process. I had to access the forms through a collection so I knew which controls to populate to the correct instance.
I noticed during my testing that I can not add more than 50 items to this collection. The problem is that I remove the key from the collection upon form closing, so I dont know why it has gotten to 50.The test I made Runs two timers. Timer 1 is set to tick every 4.5 seconds This timer loads a new form and tests a new line of product.Timer 2 ticks every 5 seconds and closes the previously opened form.I have it get the GC Total Memory upon loading the form of frmLine1t5 and upon closing the form of frmLine1t5.the results are shown in the picturesThe errors i have gotten occured when ChildForms Open: had reached 50Here are the errors:
[code]...
Possible Causes:I think that upon Form Closing it is taking longer to finish closing before a new form is loaded... But isn't vb.net suppose to finish any unfinished threads? Even if the program is single threaded?And because the form closing isn't "happening" then the key is not removed from the collection.

View 5 RepliesI am moving a lot of data to MS Excel from my application. I use a conditional statement to choose which Excel page the data is transferred into. Then a For Next statement to divide the data into various areas on the Excel sheet.The first sheet will always work correctly, but on the next conditional statement to chose the next Excel sheet no data transfers when running the program. If I step the program by hand all data all code works fine. I believe I need to pause between the conditional statements but I have been unable to get one to work.In the following code I have been trying to get a pause between to conditional statement to no avail.

View 1 RepliesI have a thread running on my application that checks a database every so often to decide whether or not to update nodes in a treeview.
Each treeview node represents a document and I have an open button that opens the document for the user.
When the document is opened, I wanted to suspend the thread that refreshes the node list until the document is closed.
I have MyThread.Suspend and MyThread.Resume. But the document viewer is on another thread.
I created functions for suspending/resuming the thread in the application. I have delegates in the viewer to call those functions from another thread. But I'm still getting an Error. "Thread is not user-suspended. Cannot be resumed" or something of the like.
But I realize that Suspend and resume are obsolete functions, so what class or objects should I be looking into and if it didn't take up too much of your time, a small example as well?
I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?

View 13 RepliesI am trying to make a start and pause button (and hence continue) to start, pause, and continue my program. The start button works but the pause button does not. Can someone look at my code and see what the pause button needs to do to pause the program? I am using VB 2005. Here is my code.

Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)
View 3 RepliesI'm not able to use edit and continue feature while debugging my project. I'm using VB 2008 Express Edition on a 32bit winXP version.
I already check on MSDN and found that this feature can be enable in dialog Tools/Options/Debugging.... However, I do not have a Debugging entry in the treeview in this option dialog. I also used to reset the Import/Export setting features in the tool menue. However this did not solve the problem as well. Then I tried to import some settings and I was able to select the option for debugging. However in the tools/option menu, the debugging feature is still not visible. Edit and Continue is not working as well
Its really a pain to debug with the current setup, as I always have to restart my application when I did some minor changes.
It appears that when IO.Directory.GetFiles tries to read a folder that it doesn't have access to it throws an exception & stops reading. Is there any way to have skip those folders & continue reading the rest of the folders?
