Send Last Entry On A Listview On The "Save" Command To A Textbox?
Sep 23, 2010
I have a listview and on save or update of the database it saves the TicketID to the listview. It also shows all the prior tickets created in the listview as well. 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.
Just lately I've been 'playing' with entering data into a ListView and I have come up with the following code which seems to be OK. Can anyone see if there is any fault with it?
I'm trying to make a program to send a command through a textbox when a button is clicked, THEN grab the output and put it into another texbox. If you could help i would be great full. This is what I have so far....
Public Class Form3 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Shell("C:DFUs-irecovery.exe")
First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.
I am trying to send a command to a command line and then submit the command. I have been trying without success to get this to work in v2008 Express and v2010 Express, Here is the code I am trying to us:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _ ByVal lpClassName As String, _ ByVal lpWindowName As String _
I am currently using psexec.exe from PsTools to send a command to a remote system to fire a command through a command prompt however I am finding that the shell I am doing does not seem to like the spaces in the path.
I have setup a page in Excel with several textboxes for data entry. I would like to be able to tab from textbox to textbox so I can enter this data as quickly as possible.
I have a listview I populate using a button and a textbox. I want to use another button (btnClear) to select and remove the last entry from the listview if there's an error.
I need help on improving the performance of a program I wrote some time back. This is the main performance issue of the program below. Basically I need to look through some data that is displayed to a user in a list view and determine if the data is a duplicate of any other data in the list. If it is I need to delete the duplicate before my program continues.The below code does the job just fine, however the list view of data has approximately 30,000 rows of data. Hence looping this list 30,000 to the power 30,000 times makes the program very slow. Note subItem(4) in the data is the "unique" identifier that I later discovered was not so unique....
This was a work around function implemented in the code back when I wrote it (not meant to be permanent). I know that listView is not Ideal to store this much data.how to store the data in a more efficient manner or improve the performance of the Search and Delete [code].....
I have an assignment where I have to develop a Windows application using Visual Basic .NET. From the form that I have designed, it should save all records in a table in a MySQL database. How should I do this? Here's what I've got so far:

I am new to programming and VB.. so go easy my buffer is about full :) I am trying to talk to a box with serial port and only need to send the command in hex. here is the protocol for the device and my code below it to turn on the box. I am not calculating/sending the correct checksum because if I sniff the string being sent to the box from another piece of software that comes with it I get 04 1C 01 DF (spaces put in for clarity) and it works. my code produces 04 1C 01 21..
I'm trying to add a name of a product to a Textbox...the name of the product is stored in a database. Now there is a Combobox with number in them....1 2 3 ect. Now if you select one of the numbers it must display that product name?
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)
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.
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.
Here is something that I had in a VB6 program that worked great and was very fast. I'm trying to get it to work in VS 2005 but i am having no luck. I can'r get an answer from searching this forum or from MSDN. Here was the VB 6 Private Declare Function sendMessageByString& Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String)

I want to retrieve a data from my mysql database into my textbox, my problem is how can i show the previous and next data in a column? because it only shows the last data entry.

Sub filltextbox() strsql = "select * from tbl_studinfo" mysqlcmd.CommandText = strsql
I hope someone can help me. I have an ATM machine connected to a server. A form takes a textBox entry as a PIN number and matches it to a card number in the same table which is the primary key. The card number is in a comboBox.Selected Item. I have used a dataset to fill the comboBox as the form loads. I have tried for days and got nowhere.
When I do it via VB express, it is clumping the code together. For example
Threading.Thread.Sleep(5000) SendKeys.Send("enter was entered ") Threading.Thread.Sleep(5000) SendKeys.Send("double tab was input ")
Instead of pausing for 5 seconds, typing the keys then pausing for another 5 seconds, it pauses for 10 seconds and then immediately types the input. I tested this on notepad.
How do I replicate the sleep feature in VB script into VB? There appears not to be a sleep feature in VB Express 2010
