I have to Repositon many TextBox in a form, but when I use Refresh() to invalidate its client area, that TextBox's Text will be disappeared until I focus to that TextBox. Are there any way to make the Text appear immediately after Refresh?
View 1 RepliesI've made a windows form in which I can change names in my databasetable 'stations'. To select which station to change I've used a databound ComboBox which gets all stations from the database table.
Now when I change the name of a station I want to get it immediatly updated in my combobox without restarting the application.
I have a simple translating program i working on in vb 2010.I have a combobox and a textbox and a button. What i have so far is when you select the option in the combobox the textbox and button will appear. then when you type something it replaces each letter with something new, in the same textbox.what i cant figure out is how to make it so where if i click the button again it translates the replaced letters back to the original ones.
View 2 RepliesI have a VB program that displays a PDF file. When the program is closed it takes 30 seconds or so before AcroRd32 process releases the PDF file. In certain circumstances if the program is restarted with in this period, the PDF file does not display. The specific circumstances is that I have a second program (re)starting the program that displays the PDF file.
a) Make the PDF file be immediately released when my program closes
b) When the PDF file is loaded test that it properly loaded so that it can be reloaded if necessary.
I have searched, but failed to find a suitable answer to this. My small app saves a text file using a savefiledialog and stream writer. Then if successful, displays a messagebox confirming sucess and asks if the user wants to open the text file now. and this is the problem... How do I determine if the user has changed the filename and or path in the savefiledialog when saving? I'd prefer not to hard code a path and file name if possible.... but that seems like the only option? and therefore I can't show the file straight after saving reliably??

I am writing an ap that monitors a website for changes. The website is for reserving campsites and I need to know when they change the date we can book a reservation. The date can change at midnight or any time during the day. It is completely random.I start the program launching a webbrowser with the URL. I have an inputboxbutton that prompts for the text to track for change. You paste the text in there and then the ap is supposed to wait for x minutes then refresh.I have a refresh button that works perfectly. Here is the code for it:

got question on using windows forms in visual
what i have going on is on one form i have a calendar that is for the month of may. when you click on may 1...it opens a form with some combo boxes and a gridview that displays the choices from the combo boxes.
my question is this..
can I just link all of the other 30 days in may to go to the same form or do I have to make 30 duplicate forms LOL...i know it is a kinda silly question but I really dont know.
It would be a travesty if the user were to click on may 2...and get a form all filled out from may 1...*blush*
Secondly if i were to have a calendar control on the form that may 1 is pointing to (at the moment I dont) how do I get the calendar contol to reflect that it is may 2 and not may 1??
this is not for a web site it is for a tire shop here in town, and it is the first project that I am doing..so it is kind of important to me.
I want to have a button on my form that will close the form itself and then reopen itself essentially refreshing the form. i have read several posts about this topic and most people say use the hide and show functions but i don't want to hide the form i want to close it. I have also tried to use the form1.refresh thing and that doesn't work either.

I've spent several hours reading through posts trying to make a data refresh/reload work and I can't.After adding a new record to the underlying table (using MSSQL) I need the datasource for that table to show this new record. My understanding is that using BindingSource.ResetBindings(False) is supposed to fetch a ew set of records and also update any control bound to it (ie ComboBox).Neither of this is happening. The new record is not there when using the navigator. The ComboBox does not show the new values either.It seems that this would be a simple basic command in VB, alas, I can't find a way to do this cleanly.I'm using SQLSERVER 2005 and VB.NET 2005. Controls are all bound to datasources...

View 5 RepliesI'm making a calculator for a finance company, it keeps track of how much money,bills, and all the totals of everything, and how much your budget is and so on.I have to have it run automatically, by that I mean no buttons at all. When a user enters a new bill or new payment, I want all the totals to reflect the change, say if I add a new bill, my budget will decrease, and so will how much money I currently have.Here is an example I've made up to show what I've done:In this sample, I have one textbox named TxtTotal, it populates all of the payments you have received, in this case up to 5 payments. I'm kind of confused on how to currectly refresh all the data. Right now I have this timer that will refresh the application every 6sec.

View 2 RepliesI have had absolutely no prior experience in any programming whatsoever. Yesterday I downloaded the visual basic 2008 express edition from Visual Basic 2008 Express Edition.
I have a small question which I am sure is very easy for somebody else to answer and I apologise in advance if this question is in the wrong section.
I wanted to make a small exe to autorun from a cd. I want to be able to hand the cd out to friends and family. So far I have achieved what I wanted with the little app. On the cd I have an exe file in a particular folder that when clicking a command button on a windows form - I would like to run this exe. At the moment I have:
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
Shell("explorer.exe ..appfolderapplication.exe")
End Sub
This finds and selects the application as required, however It does not run it. Another box comes asking me "Do you want to run or save this file?" If I click run, another box comes up "The Publisher could not be verified, are you sure you want to run this application?"
what code to I need to enter or change to make this exe run immediately as if I were the same as browsing for it and double clicking on it?
[code]I want to make the Properties Window to update the properties for X and Y at each MouseMove, so they become immediately visible for the user.

i have a datagridview with a column with comboboxes. My problem is that the changes that i am doing from comboboxes didn't occur to datagridview immediately but after the user click to another cell.
View 1 RepliesI have an issue with VS 2008 datagridview combobox control.
The combo box in question closes immediately after the CellValidation method that I wrote invalidates the input in the combo box cell. What I mean by closes immediately is that when the drop down arrow is left-clicked, once I remove my finger from the left clicking of the mouse instead of staying down so that the user can see the selection options the combo box just closes.
I'm currently using EditOnEnter as my EditMode style. (I've tried switching between the different option the same behavior exists). The datagridview is bound to a dataset which was created from my database in MS Sql Server 2005.
This problem exists on two different forms and occurs exactly the same way. I don't know what other settings to mention to help in the troubleshooting of this error, but please feel free to ask me any questions so that I may resolve this issue. By the way both forms use datagridviews tied to the same dataset, just different tables and table adapters.
Can anyone tell me how to kill a thread immediately.
I have tried MyThread.Abort, but it seems to do nothing. Someone told me it's because 'Abort' waits for the current operation to complete, but my thread will run for over 30 minutes before that happens.
I don't like the verbose way of adding DataRows one by one via Tbl.Rows.Add, so i've created this pseudo LINQ query that does nothing but adding rows implicitely:
Private Function GetData() As DataTable
Dim years = {"2010/2009", "2009/2008", "2008/2007", "2007/2006", "2006/2005", "2005/2004", "2004/2003"}
Dim tbl = New DataTable
tbl.Columns.Add(New DataColumn("Year"))
[code]....
As you can see i don't need the result of the query at all, it's only purpose is to iterate and call DataTable.Rows.Add. So the result is already available in the DataTable itself and not needed from the query.Admittedly this question is somewhat hyphotetical because there would not be a big difference in using f.e. ToList and normally a query's purpose is to return something.But anyway, what's the cheapest way(in terms of memory consumption, execution time) to execute a LINQ query when only the execution and not the result matters?Edit: Ok, thisquestion was a quick-shot and a chicken-and-egg problem. I wanted to reduce 20 lines of code to a single line but noticed that i need some kind of DataSource for the LINQ-Query. Therefor i've created the Array. But at this point i could have simply used a for-each loop as well to add the DataRows.
Conclusion: Use a LINQ-Query for what it's for: a query. Then this question is pointless since there is no cheapest way but only that which returns the correct result.
I have the following code running in a thread to enumerate the local machines in the active directory. This takes some time to complete (about 5-10 seconds) so if the user quits the application before the enum is complete the application takes 5-10 seconds to quit. I tried thread.abort but because it is waiting for For Each SubChildEntry In SubParentEntry.Children to complete it doesn't abort until this returns.
Dim childEntry As DirectoryEntry = Nothing
Dim ParentEntry As New DirectoryEntry

I have my form checked if it's dirty when a user goes to close it. If its dirty is true, the user is asked if they would like to save the data. When they click yes, the 'save event' is called. The problem I'm having is trying to get the form to completly close after saving. At the end of the save I put in me.close(), but another form closing event is triggered. Is this the correct way to dictate having the form close immediately after saving the data or is there a better way? If it is, I must have it placed in the wrong part of my code. Immediately after the "success" dialog box is displayed, I am asked if I want to save the data again.
