I have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data.
Below is code I used to get the data when the Save button is clicked. [Code]. Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part.
If I were to draw a rectangle with e.Graphics.FillRectangle(), how would I make a circular portion of the rectangle transparent?
View 1 RepliesI'm trying to prepare my first program (database). I'm creating it just according to my knowledge so it's a little bit cr. [Code] when I'm choosing the value from CB1 then values in CB2 and CB3 are changing to the same value. then in all DGV is selected row with value chosen in CB1 (if present). CB2.Text = CB1.Text
Now I would like to copy the text from specific column of chosen row in DGV1 to TB1... but only part of the text. [Code] unfortunately when I make simple data-binding without cutting the text it shows me value from actual selected row but wen I'm using Microsoft.VisualBasic.Right it shows me the cutted part from previous choose.
I need a clarification about using datagridview and query statement. i created a sql express database. In the project has been created a dataset with inside a table. In my form i used a datagridview and in automatic have been created BindingSource, TableAdapter, TableAdapterManager and BindingNavigator.
Till here everything is ok because i can add, delete and save members of the table.
Now i wanted to use another datagridview for a research but i don't understand what to use for do that.
procedure to search in a table using a new query?
I know that have been already done this kind of questions but i don't understant if using bindingsource, sqltableadapter, tableadapter ecc..

I have a gridview in asp.net using vb 2005. on " Protected Overrides Sub Render"some of the data in the columns gets modified. when i do a view source.. and look at a column1's values it says 0010. in the render i am taking a value of ab0010 and turning it into the 0010 that is seen in the view source.. later on, there is a button_click event that goes through each line of the gridview and grabs some values. Here I'm doing a CType(gvr.FindControl("column1"), Label).Text the value is coming back as ab0010. so the question is.. the view source shows something different than what is in the viewstate?
View 1 RepliesI have a DataGridView1 where I have 6 columns and 0 rows (they are added additionaly in the application) and also have a TextBox1. How can I calculate all data from the second column to the TextBox1? For example, I'll run the application and add rows, where the text in the second column will be: (4, 8, 9, 1)... it means 4 rows...
So how can I make the value of those numbers (22) show in the TextBox1, so that it will calculate the numbers and show the sum in the TextBox1?
Ok I have a datagridview that shows a bunch of data through a Database. So I have the script connect to the database and I have a while loop going so that it keeps searching through the database to make sure it "publishes" all of the data in there. My problem is, it doesn't show the first set of data. For example: I have 2 columns, one header is Name, and the other is Y/N. The data in the database:
Jim, N
Alex, Y
Pat, N
George, Y
When I run the program, and it populates the datagridview, the first set of data is removed, so it only shows Alex, Pat, and George. Does anyone know why this happens? Does it perhaps have something to do with the column headers writing over the first set of data?

Given a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.
i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.
I think this would be something like >= the formula of the red line and >= the formula of the green line?
I'd like to implement this in VB.NET

View 1 RepliesI bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.
In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,
