I am looking for ideas on giving user the option to print selected columns from a DGV. My DGV data is from bindingsource that comes rom a DataTable
I thought of CheckListBox, not sure how to set the items to be the ColumnNames of my DGV
I am stuck on how I go about using the nested for loops.Add code in the Draw button�s Click event to create the number of rows and columns selected, using the character selected Use nested For loops to create the rectangle of characters based on the user selections. The outer loop will control the number of rows. Use the value selected in the Rows combo to determine the stopping value of the outer loop. Use the value selected in the Columns combo to determine the stopping value of the inner loop, which controls the number of characters per line.
Public Class MainForm
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a scenario where-in I have a DataTable with certain columns "Col1, Col2, Col3". I want to copy just "Col2, Col3" into another DataTable which has a primary key "ID". What is the best way to copy them. There are 5000+ records and performance is a key factor.I tried with Select, DefaultView.RowsFilter but no success. I know one option is to loop through all records an copy data one by one in second DataTable. But wanted to know a better way.

When user clicks on a button on my form, it sends the datagridview on that form to another class that [basically] does a bunch of stuff and shows a dialog with a print preview. Everything works perfectly fine, except that if a user switches around columns it won't print them in that current order. For example, if user moves the LastName column before FirstName column, then it should print in that order, but it prints in the column order that the datagridview was originally loaded. The dgv1, is the datagridview that was originally loaded, not the current one. [Code]

I have multiple tables that I need to pull and display data from. I have created a new query in the TableAdapter of one table to pull data from related tables based on a parameter. In the Query Designer I can run my query and see all of the columns requested in my SELECT statement, however when I bind this table to a DataGridView and call the new query, it only returns the original columns from Table1.How do I see all of the columns I selected in my query?

View 8 RepliesI have the following:
1) 1,000 multi-paged PDF files (say 00000001.pdf, 00000002.pdf, ..., 00160000.pdf)
2) A list of pages for each document to print
I have a data-driven many-page print system that works well, each page containing logically what's next following the preceding page. To output a sub-set of pages, how can I avoid outputting pages before the first one that I actually want to send to the printer? To pick and assemble the data correctly my PrintDocument1 process has to run until I reach the 1st page to print, so it would be neat at the end of each unwanted page to 'waste' them - then from the 1st wanted page the usual e.HasMorePages will do the job.
I thought maybe PrintDocument1.Dispose() or PrintDocument1=Nothing might void the early pages I don't want (then looping back internally to construct the next page), but no. Is there another way to 'ditch' pages until the required one is reached? Or do I have to avoid using every e.Graphics.DrawString) statement until I get to the right start point? That would of course do the job, but is pretty clumsy

My goal is to connect to my database either manually or using an sqladapater, and get information from two of my databases on sql server 2005.

I have been able to do the exercise's in the first 2 chapters and half the exercise's in the third chapter of the text book (programming in visual basic 2008, Julia Case Bradley & Anita C. Millspaugh). but this one is making my head want to explode. please point me in the right direction with this.
Heres the problem. The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours). The Calculate button will determine the bonus earned by this employee, and the Clear button will clear only the name, hours-worked, and bonus amount fields. A Print button allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.

Anyway, I was just wondering if anyone knows how to do these from a simple text box. i.e. 'TextBox1'.
I'm just learning VB and it's only a simple text editor but I can't find any good sites or posts that help me in understanding how to do it. These are not really covered in any of the 'beginner' books I have acquired either.
My instructor told us how to print documents and how to use databases. What the instructor did not mention is how to print or print a preview of records within a DatabaseDataSet. The book "Programming in Visual Basic 2010" does not explain how to print or do a print preview of Database Source records from within a form. The only thing I was told was to test the print document first before you try to do a print preview. Within a form I used a DataGridView to add, delete, and update the database. So now all I need to do is figure out how to print the updated records from the DataGridView and how to print a preview of the records within the DataGridView. So I hope my question is clear enough to give me assistance on how I can perform these two actions. Thanks this would be a great help, and since the class is online we can get assistance from any sources that we have.
