Saving A Modified TextBox Entry

Apr 29, 2010

Okay, that snippet made the file I was trying to open in the %USERNAME%AppDataLocal folder worked perfectly, again, many thanks - But now I'm 3/4 of the way through my program, and I've hit a wall - I have the exact same program I made in VB6, and it works to perfection, but I am TRYING to switch over to .NET, and am finding a lot of difficulties in getting certain things to work - My biggest headache right now [ Which is basically the finishing of my program ] is a bit hard to explain, so this may be a rather long post: One of my programs that I use to keep track of my Music hard drive outputs to an XML file, in which there is one line I would like to be able to 'Replace' through the program I am making now to a different user-defined string, and close [ Applying string change/save ] the XML file. I have my Main Form, a TextBox1 [ I can't get the XML to open in a ListBox like I wanted ], TextBox2, a 'Locate String' Button, a 'Modify' Button, and an Exit Button. I open the XML file with this in my Form1_Load event into my TextBox1:[code]

The <DateValue> is the line I want to be able to modify [ Which the entire string looks like this: <DateValue>2010-04-10T10:00:03.5009756-04:00 </DateValue>, and I want to be able to change the date and time to whatever the user specifies ], which once the XML is loaded into TextBox1, when the 'Modify' Button is clicked, that string is then loaded into TextBox2... This is where I am lost - How can I apply the modified string to the TextBox1.Text [ Entire XML file ], and save it upon program end, without the rest of the XML lines being disturbed? I realized I needed another Button - The 'Modify' Button now loads the selected string into TextBox2, and I have a 3rd Button to 'Apply Modification', which I want to update the <DateValue> string in the TextBox1 [ Full XML file ] from the modified string in TextBox2, then save on exit - Hope this helped clarify things.So here's the routine:

1. Form loads, opening the XML file, and loading it into TextBox1.
2. User clicks 'Modify' Button to load searched string into TextBox2.
3. User modifies TextBox2 entry.
4. User clicks 'Apply Modification' Button, which changes the searched string in TextBox1 to the modified user-defined string.
5. User clicks 'Exit', which saves the XML changes from TextBox1 [ Without messing up the XML file format ], and the program ends.

Drawing Shapes Onto A Pic Box And Saving The Modified Image?

Aug 25, 2009

The aim of my program is to load a picture into an pic box, then to be able to place multiple shapes on the picture in the pic box by clicking on the location where i want the shape. The type of shape will depend on the radio button which has been selected. Basically all i want is choice of X or O. (its not tic tac toe either At the end of it all i want to be able to save the image WITH the shapes on it, doesnt matter what format its in (gif, jpg, bmp) as long as it has color and i can see the original image with the shapes included.

I have made several attempts at this, and this is what i have so far. (I am brand new to VB and programming so i need all the help i can get) I have hit a wall with how far previous examples can get me.

Cannot Edit Entry After Saving First Time

May 27, 2010

When ever I add a new entry into the database, it will do it. When I click save, it will save it. When I go back to edit the entry after it was saved the first time, and I hit save again, I get a concurrency violation? It only does it when I add an entry. If I close the program out and restart it again I can save all day long as long as I don't add a new entry. First of all, dunno where the violation is coming from, but I only have a message box on my catch statement on the save button.

I have added it to the database using the following code 100 times and it has always worked:
Me.shuttlerunsbindingsource.addnew()

My save code is:
Try Me.Validate()
Me.ShuttleRunsBindingSource.EndEdit()
Me.ShuttleRunsTableAdapter.Update(Me.ShuttleRunsDataSet.ShuttleRuns)
[Code] .....

Why after a million times of using this exact same code is it not working? It will save all day long no problem as long as I don't add a new entry. Here is my add
Try ShuttleRunsBindingSource.AddNew()
EmployeeInitialsTextBox.Text = lblUser.Text
Catch ex As Exception
MessageBox.Show("UNABLE TO ADD! " & ex.Message) End Try

The message box for the add code never shows so I can't see that is causing any trouble. I am using VS2010 and a local database, not SQL. I just tried doing it again, I added an entry, I saved it, I got a successful message. I then tried to change something and I got a concurrency violation when I clicked save again. I then tried to delete an entry and it successfully deleted it, but when I went to edit another entry and save I got the violation.

Format Textbox After Data Entry?

Jun 18, 2012

Back on my form with a ton of financial data entry textboxes but I want to have the data formatted at runtime, as I enter the data.I have a format declared as Public Const cFmtCurrency = "##,###,###" ' don't need decimal for the local China currency What would be the least compicated way to have these textboxes (19 of them) format the Long Integer values as I enter the data. I think a Lost Focus event would be silly; there must be a better, more efficient way.Also want to use this format when I retreive records from the db (don't see a reason to mask data in db)

Getting Timer To Check TextBox For An Entry?

May 20, 2011

I've got a program and what I need is for a Timer (running in a different thread) to constantly be checking a TextBox for an entry that is similar to:Quote"(PlayerName)" has joined the server.Where (PlayerName) would be replaced with the players name in the TextBox. What I would need the TextBox to do after it has found this entry is to add (PlayerName) to a listbox. If someone can help me out this far then I can use the same code to get it to remove the player when they leave.Below is a picture of what it should look like inside the program.

Forms :: Auto-Detect BarCode Scan Entry OR Manual Entry - Cash Register?

Sep 8, 2009

i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....

Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.

Communications :: Differentiating Bar Code Entry To Keyboard Entry?

Jul 10, 2009

I am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:

1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?

2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).

Password Characters - Get A Textbox Being Using For Password Entry To Display The Black Circle

Feb 10, 2009

How do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?

I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!

Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

I would like to pass the very last entry ie in this case TicketID to a textbox so that it prints out a ticket with the ticketID for the user.

Don't really want to loop through all the other tickets in the listview since it could end up running into the tens of thousands of numbers.
