I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.

I am trying to pull data from a cell in the currently selected row in a DataGridView control. I fill the control with data from a SQL database through a dataset.I am trying to retrieve the index of the currently selected row so that I can pull the data out of the first cell in that row. Here is the code I currently have:

I 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,

View 2 RepliesI want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.
Below code is written in such a way to retrieve all selected check box values But its retieve only the first selected value

I have two datetimepicker controls on my form:
dtpPickup and dtpReturn
I need a way to ensure that the dtpReturn date selected is after the dtpPickup, and not before. How do I do that? And also, how do I get the values of the datetimepicker selected controls? Also, how can I set the values of the datetimepickers to these two private variables?
Private mdatStart As DateTime
Private mdatEnd As DateTime
It will not let me save them with the Sub for the date time pickers.
I have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

View 1 Repliesi have a form with 3 combo boxes. The value of the combo boxes generates a sql query with 3 parameters. The sql generates a RDLC report.
For example:
Combox1 with values(v1,v2,v3,ALL)
Combox2 with values(v1,v2,ALL)
Combox3 with values(v1,v2,v3,4,ALL)
Me.ExampleTableAdapter.QueryWithParams(Me.ExampleDataSet.Table, Combobox1.SelectedIndex, Combobox2.SelectedIndex,Combobox1.SelectedIndex)
QueryWithParams:SELECT * FROM Table WHERE Column1=@c1 AND Column2=@c2 AND Column3=@c3 Ok the problem is when the selected value is ALL in the combo X, i cannot get the values because i must change the query and kick out the parameter.For example:If the combo1,combo2,combo3 have the values ALL. I don't need parameters.SELECT * FROM Table IF the combo1 is ALL.SELECT * FROM Table WHERE Column2=@c2 AND Column3=@c3 If combo1 and combo3 are ALL SELECT* FROM Table WHERE Column2=@c2 Then in code I look which is the selected value of the combo and upon it i do the query.Is there a way that i do this thing without generating all 8 types of queries?PS. I cannot use stored procedures because i'm using SQL Server Compact

View 1 RepliesIs there a way to to combine line's 1 and 2? I only want to loop through a list of the selected items in this listbox. This works just fine, I just wondered if there was a collection of selected values returned that I could use to avoid having to do it this way.

I have a little problem. Basicly, I have a ListBox, TrackBar, TextBox and 2 Buttons. What I want now is that:
1. If user clicks on Button1, the program will add text from TextBox to ListBox (I know code for that one).
2. When user clicks on ListBox item, ListBox item selected, and then clicks on Button2, program will set the value of SelectedItem to TrackBar. Here's an example:
User writes "Value is 50." in TextBox, clicks on Button1 and program adds "Value is 50." to ListBox. Now user selects ListBoxItem and clicks on Button2. Program sets TrackBar value to 50.
I am having trouble using the values that were selected from the dropdown list. How would you reccommend passing the selected values from the view?Ideally, we want to use the selected dropdown values to determine a query.

I loaded up a checkedListBox with items from a .txt file. The .txt file has itemName, ItemPrice. Every item that gets checked shows up in a listBox on another form. The problem that I am having though is that I need to accumulate the itemPrices of the selected items to show up in a textBox, but the only price that shows up is the price of the item in the checkedListBox that has the focus. I have tried a few different things, but none of them seem to pan out. Any suggestions. I'll add the code to this so that you can get a better idea of what I am missing. I would really appreciate any help with this that I can get. Thank You for taking the time to read this. [Code]

View 2 RepliesOnce again I have hit a brick wall here. I have a combobox in which the user types the server name and then clicks on button 'CONNECT' to populate the next combobox which contains all the databases in that
server. Then after the user selects a database, I have another button that he/she click and I want to retrieve file groups from a specific table.

I'm learning .NET and I've got a question about user controls. I'm using VS 2010.. I've created an user control, which contains a textbox (code), a button and a label. When you fill in the textbox, the system searches of the codes exists, if so, the description is showed in the label, else it's cleared. When you click the button, a form opens with a datagrid where you can select a code. When you select a code in the datagrid, the code textbox should be filled in with the selected code. How do you return the selected value to the custom control? I've created a public property in the custom control, but i can't access it.
