I currently have an unlimited amount of columns and rows in a DataGrid. Pendinginformation from a user I would like to display every row from the datagrid into a checkedListBox but I only want to show specific columns depending on their column Names. Currently my code will display every row. My problem is getting only the selected columns depending on the name of their header.
The code that I have currently is:
For Each row As DataGridViewRow In CSVInput.DataGrid1.Rows
If Not row.IsNewRow Then
I'm trying to learn a little about pulling information from other applications and finding it pretty difficult to find what it is I need to do. Let me give you an example of what I'm trying to do and perhaps someone can point me in the direction I need to work in.
I want to read Ventrilo from my VB application, specifically I want to know when someone is talking in the channel I am in. That is my end goal. I can pull the handle using FindWindow
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _ (ByVal lpClassName As String, _ ByVal lpWindowName As String) As Long
Im just pulling information from SQL and populating textboxes etc.My question is firstly i have an issue because i can figure out how to do it, and secondly is there an easier way of writing this.So my Issue, i wrote a function to connect to SQL and pull information back which is fine it fills DS(Dataset) and then i want to be able to assign the relevant information within the DS to the desired textboxes,
First time actually doing anything with xml so I've been trying to follow some examples but im not getting anywhere with them, can you show me where im going wrong?First off Im pulling an xml file from the web as a string and then loading that into an xml document, heres an example of one:
We are writing a program that pulls a Teacher from a database, then you select the "period" 1 - 7. What is happening is if we pick period 1 on teacher john doe. Then when you pick another teacher it doesn't clear the period that we selected before. How do we clear this information every time we select a different teacher?
I've created a Gridview control that pulls some data from my database, but doesn't display all of the information I'm hoping it gathers. I choose not to display the primary key for user interface purposes, but require that key for basic operations on the grid.I'm currently attempting to add a "Delete" option to the table, but unfortunately I'm having very little luck. Here's my .aspx file.
I have tried to query the data in Access but the filter that is on the query does not transfer over to the datagrid. I would like to be able to filter the information on the datagrid, but I do not want to use a text box or combo box. Here is a sample of the data that I am working with:
What is the best way to validate whether or not information exists in a datagrid. Let me give a situation.
What I'm trying to do here is allow the user to search and sort the dgv based off of the character or string that is he/she inputs into a textbox. The things I want to validate are:
The textbox is not blank, and if not blank has valid information. (easy enough)
The dgv has actually been populated from the dataset!!!!!
The second I can't seem to nail down, regardless of what I use. I have tried using rowcollections, columns.count(), cell, item, and a few other properties all of which either get skipped over by my if statements or throw an index is out of range error.
In my datagrid my sql statement uses a have clause to get set information and i am having countless errors
My code is as shown below, were am i going wrong
con.Open() cmd.Connection = con Dim da As New SqlDataAdapter("SELECT MONTH(Head.SalesDate) AS Month, Detail.ProductID, Detail.Qty, SUM (Detail.Qty) AS TotalSold, SUM(Detail.Qty / 30) AS Average FROM Head INNER JOIN
I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?
I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.
Private Function currentv(ByVal version As String) As String Dim filePath As String filePath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) & ".minecraftin"
[Code]....
im trying to pull from the file located at: filepath & "rpgversion.txt"
and display it in the textbox2
as "0.5.3" for example

I also got as far as creating an XPath Query: (/main/SourceType/@ID) but for the life of me do not know what to do with it. Im trying to pull all source type ID's into an array of strings if it is possible!
I have a textbox where a user enters the time in minutes:seconds format. I want to take whatever number that is in front of the colon and store it in a variable called minutes, and whatever is after the colon and store it in a variable called seconds. I have everything declared and my code written, I just don't know how to take the text from a textbox and when the value is stored in my variable to only include up to the colon. I think it has to do something with the string remove method, and I can remove the colon, but I don't know how to get the characters after it. (and I can't use number of characters because I don't know how many the user will enter)
I've been having some trouble being able to pull the text from the monthly balance column and displaying in the textbox (remainbalancebox) beneath it, all I can make it do is display the text in the bottom left column, when all i really want displayed is the last text on the RIGHT column?
here's what I'm doing. I'm putting together a program that will allow employees that work under me to all submit shift reports in the same format instead of getting multiple different formatted text files.
I have a list box that they add "actions" they've performed throughout the day. It's populated by a combo box and some text boxes.I've got it all functioning minus one aspect...
[Code]...
Here's my problem... it's only outputting the FIRST set of items. The "Upgraded" accounts all list but the "Downgraded" and "Canceled" are not there.In a perfect world, I wouldn't ever need to worry about "Canceled" or "Downgraded" but... the world isn't perfect so,
I know this is pretty simple but Im a little stuck. I need to take items from a listbox and print however many items are in that listbox to a receipt. So far I have
For i = 0 To lstselectedtoppings.items.count - 1 lblreceipt.text = lstselectedtoppings.items(i) Next i
I know this is pretty close to what I need , what am I missing though?
Basically we're creating a multiform app for class with 3 different forms. its going to be a game. My startup form asks only for your name and your total units to play with. Then you're able to click a play button, which opens up a new form that will display your total units available (from the first form) and allow you to enter how much you wish to wager for that round.
I wish to know how to pull the info from my textbox (txtUnits) on the first form (frmWelcome) and have it show up in a label(lblCurrentGameStake) on my second form (frmMain).I thought about maybe putting the value in a string and then calling that on my second form but it doesn't work. Private Sub btnPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlay.Click strStake = txtUnits.Text
I am pulling urls into excel, but excel formats the data. if a website displays 000.4500 excel formats it to .45.... i need everything exactly like displayed on the webpage, so excel should not do anything with it.
I tried formatting the worksheet to text (keep everything as entered exactly) and that did not solve the problem.
I can show code, but i'm not sure if this is a coding problem at all. I am just confused and can't seem to find any good information on this problem.
how to pull information from Access and display it on a form with many different txtBoxes. For example I have 2 Queires written as well as the "Fill,GetData" for the tableAdapter. I just can't figure out how to say txtBox1 you use Query1 and txtBox2 use Query2. I'm getting data in my text boxes just not that information I need to be there so I have it bound properly as well as pulling from the right column of the data base. I'm using VB.Net 2005 and a Access 2000 Database if that helps/matters
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.
I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _ lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
I am designing a backup/restore utility for work.atm i have been able to populate field for PC name, IP address, MAC address, number of printers installed on the PC but i am wondering is it possble to get all the printer information 'with the click of a button' to print all information like the prnmngr.vbs script down.I am able to run a batch file but i wanna get it to go from that app or even embed to batch file to the app and run it form there .
So what's happening is that I click the Edit button, type the updated values and hit Update. But the code-behind gets the original values not the updated values. I can't figure out why. It's always worked before.
