I have a dataview an i would like to show the count property in a text box.
i tryied the following
me.textbox1.DataBindings.add(new DataBindind("Text",DataView,"Count"))
But i have a exception.
I want to type the characters from right to left (to behave as a right alignment). But I am not supposed to use the Right Alignment property or the RighttoLeft property of a text box.For example, I want to enter the characters of a string from right and each character should shift one space left so that the user can enter another character after that.
View 13 RepliesI have a simple Sub:
[code]...
It's job is to scroll the textbox (txt_folderactivity) after I update the text box with a new entry. The textbox is multi-line, so this keeps us at the bottom so we can see the new stuff. This sub gets called whenever any of the other subs add a line for things like file rename, deletion, etc. based on file system events (using Public watchFolder as FileSystemWatcher).I had a crossthread issue with just updating the textbox, but I wrote in a Delegate /Invoke for that and it works fine (something I found online earlier this morning), but now I have another issue and I'm not sure how to work it.
I'm getting a crossthread issue with this specific Sub specifically at the SelectionLength, and I'd like to set it up with a Delegate and Invoke and such, but I don't know how specifically. I've searched and read, but I don't get it. Do I need a seperate invoke on each of the 3 lines, or is there an overarching Invoke for the whole bit I'm still new-ish to VB and I don't know how to proceed. I've read some MSDN pages and stuff, but they aren't explaining what the problems is really and what I need to do (or prehaps I'm just not getting it).
Windows Forms, VB application... Forgive me in advance for this very elementary question but I am overlooking something really simple here. I would like to have a label show the current value of a variable as the for each loop runs.. I created a very simple Button Click event to figure out where its failing. As it is right now the value does not display until after the for each loop finishes running, which it should actually display the counter value each time it runs through... I know this is possible and really simple because I did it years back but for the life of me cant figure out why I am missing the bar as it should constantly update the label to reflect that?Test Sub is as follows:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer = 0
For x As Integer = 1 To 200000

I'm trying to write a Database manager in VB (2010) that updates a SQL database that compiles and summarizes my financial records. The code works, but I'm having issues with one exception that I think I understand, but can't circumvent. I've built an I/O form that enters a series of purchases and sales into a temporary datatable. After review of the list, the program connects to the database and executes the SQL. That all works and isn't a problem.

View 1 RepliesI have two UserControls already loaded how to change TextBox text property on a UserControl from the other loaded one.
View 1 RepliesThis is my first post on this forum, so please excuse me if I'm posting wrong. Anyway, I've been having an issue that I've never seen before and is driving me nut, I have a windows form on which I have placed many textboxes that display information from a MS SQL database. The user can then change these values and hit a "save" button which writes the changes to the database. I also have certain textboxes that with the "on leave" event (after a user enters a possible new value) trigger a method that recalculates some of the other fields based on the new information. Hopefully that all makes sense.
So the problem is, when I run through this "recalc" method the first time around, it doesn't update those textboxes that it's supposed to. However, when I put a breakpoint in and debug through it, the debugger shows it putting in the correct values into the textboxes. It's just as soon as the method is done, it puts them back to blank, or whatever they were before
'Rebind stuff here
lblCabinets.Text = curMfg.ToString("c")
txtCabinets.Text = curMfg.ToString("c")

I have created a new class with a string property called "Text".
The property will hold a sentence typed by the user.
I use "KeyPress" event to get the character pressed and use "Console.Text = Console.Text & e.KeyChar" to update the property. Where console is an instance of the class.
The problem is when I press "Delete" nothing happen.
That's the code within the event scope
MsgBox(Asc(e.KeyChar))
Console.Text = Console.Text & e.KeyChar
MsgBox(Console.Text)
I am trying to use several Class arrays to hold values that I will cycle through at a later point to perform some calculations. I need to change the array sizes to fit the data as it is entered. I am using one procedure to set the first element of each array and then a separate procedure to pass the additional values as they are entered.
Until my last attempt at changing my code, my StartBalance sub seemed to work, I could step through and see the values assigned to the class arrays in the code block. However, when it moved on to the Transaction sub, it did not recognize that the first set of values were set, the array shows zero values for index 1.
I have gone through several changes trying different ideas from reading blogs and articles, but I guess I am not understanding how these work. I even used the class arrays directly instead of the Property procedures to see if I would get a different result, but I do not.
I believe I must be approaching this incorrectly and though I can find dozens of examples of setting class variables and even a couple on using arrays as class variable, I can not find any that show how to then pass values to those arrays.

Using Office automation in Word 2007, I view the Document Information Panel, showing me properties of a document that resides in a SharePoint location. Using VS 2008, I interrogate the following in the Immediate Window:
[code]...
but I don't see a corresponding change to the screen. I do however see that, on Advanced Properties/Custom Tab that a Custom Property by the name of "Process Name" has been recorded with the value "New Value"There seems to be some kind of one way mapping going on between "server" and "custom" properties, but the really strange part is:I can update SOME server properties, others I cannot.I don't know a darn thing about SharePoint, other than as a dumb user. And getting any help from a SharePoint admin in my company is probably a very long shot...I checked all of Word's Built-in Properties and Custom Properties, I decided that none of them can be used to update the "Process Name" "server" property.How can I update this stubborn property? Most of the server properties I can update, a few I cannot.I see some articles referring to using what looks like "SharePoint objects." Do I need to download an SDK just to populate these properties? So far I've used Office automation, because I am running locally on the user's PC and pre-filling documents using the Word object model. All that is left is to finish populating the last couple of server properties after I copied the doc to a Sharepoint folder.

First I click on the button to open the port. Then I do this code so whenever I receive data from a serial port connection, "Hello" string is written in the text field.. I debugged it, made sure COM Port is open, and data seems to pass to the textbox.. because when I put my mouse over to display the values inside the textbox it shows that "Hello" is stored.. and I tried doing the textbox1.refresh() but still nothing happens.. the textbox remains empty!

View 1 RepliesI've got a program which acts as a schedule for sporting events.The program allows users to fill in event details and they get saved into a directory for the selected date and venue, and in it are text files with the details, and then on another page is a listbox containing all of these directories so that the user can view saved events, and the page retrieves the details from the text files and displays them how I wanted it to.BUT, my 'update' feature just will not work.
basically, I want the user to be able to change the details and press 'update' which will then write the new information to the relevant text files, BUT i get this error in debug mode:
The process cannot access the file 'C:Events PlannerSaturday, May 29, 2010 testvenue.txt' because it is being used by another process.
The code I'm using is below, and from what I've learned, and how I've already coded this program, it should work right?

venueReaderUpdate = _
