VS 2005 DGV Skip Rows
Dec 30, 2011
following is the code at button event which copy data from one DGV (dgvAccesList) to another DGV (dgvProbReport) and its working properly. Its paste data to 3rd and 4th column of destination DGV.But the problem is that, if at source DGV first column and second column have data..lets say up to 2 rows..then its copied data starting from 3rd row..for the 3rd and 4th column..which is incorrect..its should be always start with first row of third and fourth column.[code]

I am using MSHFLEXGRID control to display data from an access-database table. The grid contains entries some of which are to be selected by the user but I want some of the rows to be disabled/skipped(avoid selection of those rows). I have grayed out the unusable rows and dont want the gray rows to be selected.
Code:
Private Sub MSHFlexGrid1_RowColChange(ByVal sender As Object, ByVal e As System.EventArgs) Handles MSHFlexGrid1.RowColChange
[code].....

I would like to create a group/collection/set of unfinished rows that I can later add to a datatable.I have tried to do this by creating a DataRowCollection, and then create a new row based on the table I want then add it to the collection. Doing that I get a NullReferenceException though.Using the new keyword for dr does not work.[code]......

how to print, and got it working pretty well. The text string I have printing into a rectangle, and if a word does not fit it will wrap down to the next line, and then keep going like that, but now I need to split my page into three different areas that will each print different text.I am pretty sure I could draw three different rectangels then draw the text I need on each of them, but is it possible to somehow merge them together into a single rectangle that will be printed?

how do I count all non-new rows in a datagridview?
datagridview always give a blank row at the last row, and when i do a rows.count, it always adds up
is there a way to count only non new rows, or do i just need to subtract 1 every count (which is weird)

"Deleting rows from multiple tables in SQL 2005". I need to delete all the rows in the multiple rows where it's the same UserId. My Delete command below:
Delete From tableA
From tableA INNER JOIN
tableB ON tableA.UserId = tableB.UserId INNER JOIN
tableC ON tableA.UserId = tableC.UserId INNER JOIN
tableD ON tableA.UserId = tableD.UserId
Where (tableA.UserId = @UserId) AND (tableB.UserId = @UserId) AND (tableC.UserId = @UserId) AND (tableD.UserId = @UserId)
What is happening from the above query is only the rows from tableA is getting deleted.

I'm trying to populate a datagridview with rows in the sqlserver 2005.how to use DataAdapters too well so I go back and forth between hard code and controls.I used the Datagridview control and added columns to it this way. 2 combo boxes, a check box, and 2 text boxes.The 2 combo boxes are populated with values that are already in sql Server for users to pick from. The task is displaying the description while the value is the task_ID. Here is my form on load:
Private Sub frmTimeSheet_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
currentDate = Date.Now.ToShortDateString
lblDate.Text = currentDate

As a preface, I am brand new to using SQL Server 2005; I know how to use the SELECT, UPDATE, DELETE, and INSERT commands and that's about it. I am also using Express Edition on my local PC (E8400 processor, 8GB of DDR2-800, 2 x 640GB SATA-II HDD in RAID 1)
I have a table that I set up with 8 columns, all are NVARCHAR(Max) and I allow Null. I know in concept what a primary key is, but I don't have one (nor do I know how to set one up).
My VB.NET program that I'm working on is downloading a historical stock price chart from Yahoo, for every single ticker symbol in existence. The first 50,000 rows or so I added was super fast. Then I went to bed, and when I woke up it was still running - but the rate of row additions has slowed waaaaaay down; I noticed this around row 300,000. I always expected the rate of row addition to be constant over time, but obviously this is not so!
From browsing other Stack Overflow questions, I suspect my slow down is related to my piss-poor table setup. If this is the case, where should I begin first to fix this, and are there any good resources I could read up on to get started? I'm hoping this is something simple I can fix [code]....

I created a reporting utility for my users to view, send (via email), export SSRS reports. I have set up date parameter boxes with calendar drop down and they are able to send via email a URL link that would either display the report via ReportViewer or send a link that would let then view the report in Excel or PDF. This is working just fine. Now I just added a button for adding new email addresses and a new windows form with a textbox for entering the email address and a command button for Save Email Address. I get an error msg Quote: Objects added to a BindingSource's list must all be of the same type.[code]

I am looking for some advice on this since I know nothing about database projects or sql, except that they have data stored in tables and rows. I have a sql back up text file from my forum, and I would like to bring that in to a VB.net sql db project. What do I need to do, to accomplish this?

I see the DataGridView control has a property "AllowUserToAddRows" that I can turn on or off but what if I want the ability to be context dependent. i.e. I want an event that will fire when the user attempts to add a row in which I can cancel if certain conditions aren't met but I can't find an appropriate event.

i want to save into my sql server 2000 database multiples rows of a datagridview. i tryed something that first was working good, but i did a code change removing a column so now i'm trying to save again but i can't do it. It's shows me a message error like this: THERE ARE FEWER COLUMNS IN THE INSERT STATEMENT THAN VALUES ESPECIFIED IN THE VALUES CLAUSE. I rewrite the code, delete and add a new table and my code has the same values in the insert than my values clause. I don't know what else i have to do.
Here is my code
Private Sub cmdAceptar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAceptar.Click

I have a datagridview control. I want to save the rows and then restore them the next time I run the program.
How do I write the rows out to an XML file?
I know how to fill the rows from an XML file. But when I've done so I can't add any more rows. It gives the following exception when I try: Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound. What can I do about this?
Or is there an easier way to save and restore the rows?

VB6 had a feature for it's datagrid where the user could use the mouse to drag the row divider in a datagrid and when the user released the mouse button, all the rows in the datagrid would resize to match the one the user resized (Excel does the same thing if you have all rows highlighted).

'this calls the connection sub
connection()
SQL = "SELECT * FROM Customers WHERE Surname Like '" & Textbox1.Text & "%'"
'this calls the DatagridFill sub
Datagridfill()
This is my current code, it searches for anything entered into the textbox against the row "surname", but I also have a first name row and a Order ID row. Instead of searching against one row, i want to to search all the rows, and fill the datagrid with anything it matches it with.

I have added an unbound checkbox column to my DGV. I have two questions on handling it:
1. How to have a checkbox on this Column header, which on checking must check all the rows in the DGV and vice versa?
2. How do i get the Boolean value of the checked rows in DGV on event handling? In other words, how do i know what rows are selected?

I have created a datatable and now i need to print it,so i did the following:
Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim xPos As Single = 20
[CODE]...
The code works fine.But in the above code as you can see that i am printing the each rows content of the datatable one by one and after printing all the contents of a single row i am looping the code again for printing each and every row present in the datatable. So i want to know that inspite of printing each and every data present in the row of the datatable,is it possible to print the entire datarow at a time and then loop through all the rows present in the datatable?

I have a 'For Each' loop that contains some items I don't want to analyse. Now I use a GoTo command to 'skip' an item. But this is not very elegant and (knowing .NET) there is probably a way to skip to the next item without using GoTo.
I'll show you a simplified version of my loop, designed to add all animals to a list, except the Leopard :
(Indeed, simplified, because there's like two pages of code in the real loop. )[code]....
