I have created a Datagridview with 4 Columns, EJ: ID, Name, Quantity, other..But i want to fill these 3 Columns from MySQL EJ:[code]but this creates new columns and does not write to the existing, took a while looking for a solution but only find methods like this.
View 1 RepliesIs it possible to show all the Columns from a datagridview in a listbox?
When i selected a row , it shows all tht Colloms in the listbox.
i fill the datagridview with code from a Excel file.
I only want specific columns to show up in my DataGridView, so I run a dynamic sql query to select specific columns from a table on a sql server(I know its slow, but its only used once a day). However, every column from the table shows up in the datagrid, and I can't figure out what i'm doing wrong.
Public Class Assign_Priorities
Dim connect As New SqlConnection("Data Source=IRNTS4SQL;Initial Catalog=Materials;Integrated Security=True")
Dim ds As New DataSet
Dim da As New SqlDataAdapter("SELECT [Priority], [Tool Type], [Lot Number], [Process], [Priority Notes], [Quantity], [Time Job Entry] from [FPAD Process Log]", connect)

I need to get a table on my Form that has different columns from differen tables.As I call many tables by their Identity ID, I also need a way to show the information from that table.I created a query in my TableAdapter which selects information from 2 different tables. Tested it in the query builder and all was OK.I tried to put an empty DataGridView onto my Form and inserted the correct BindingSource for my Data Source.I then added a query and selected the query I created in my TableAdapter.

Create a generic label method:
Public Function buildBasicLabel(ByVal labelName As Label, ByVal text As String, ByVal font As Font, ByVal align As Integer)
Dim tmpLabel
[Code]....
For some reason, the label is not lining up with the others once I span it. I'm trying to span it to get all the text to show but once I do, it starts pushing it over. I don't see anywhere where I restrict the size so that shouldn't be the issue.
I tried doing all this in the design and it works just fine. Mimicking the designer code doesn't seem to fix it either unless I'm doing something seriously wrong...
Posting images for clarity. NOTE: The borders are just to show the label alignment and the text should read "Flat-Footed AC"
IMAGE 1: Spanning 1 column (doesn't show all text)
IMAGE 2: Spanning 3 columns (still doesn't show text and you can see it's starting to dis-align)
IMAGE 3: Spanning 6 columns (Still doesn't show text and greatly dis-aligned. It should at least show all the text)
i'm having a problem converting a date to the right format. Below is the code I am using:
Dim getDate As DateTime
getDate = DateTime.Now
With cmdParent.Parameters
.Add("@date_created", OdbcType.DateTime).Value = getDate
.Add("@last_updated", OdbcType.DateTime).Value = getDate

This causes the following error: ERROR [HY000] [MySQL][ODBC 3.51 Driver][mysqld-5.5.8-enterprise-commercial-advanced]Incorrect datetime value: '' for column 'date_created' at row 1
This is being inserted in a MySQL db. The date_created column is of type datetime.

i've been attempting to update a DateTime Field in a MySQL Table i've created via vb.net. I've made many attempts however i'm still getting the error that i have an error in my SQL Syntax. The format that the DateTime in Vb.net is 6/21/2011 12:46:25 PM. I need to convert that to the MySQL DateTime Format which is 2011-06-21 12:46:25 and also is running on a 24 hour clock. I've searched many forums and haven't found a conclusive solution yet. Below is the code i have so far, with attempting any DateTime Conversion.

View 5 RepliesI have this question about how to retrieve a column with DateTime from MySQL as String and put the data in a textbox. [code]I want to use this to cross reference with other table in other database, but to do that i need to copy the data into a textbox as string or a datetimepicker as datetime.
View 2 RepliesI am having trouble with a mySQL query with the .NET connector. When I create the query, it automatically creates my parameters as objects. I usually change the type to the correct type, which in this case is Date, but I get different results passing in the parameter as a date.When I do "Preview Query" as an object, I get the correct results, but bad results as a Date. I would just leave them as objects, but it errors out when I try to pass a date in.Here's the part of my query that I'm having trouble with:
(Tickets.Resolved >= str_to_date(@startDate, '%m/%d/%Y')) AND (Tickets.Resolved <= str_to_date(@endDate, '%m/%d/%Y')) AND
(Tickets.Status = 'resolved' OR
Tickets.Status = 'rejected')

I have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.
I'm trying to format a datetime field to just show the date. The datetime is bound to an asp:label and for the Text attribute I have tried the following....
Text= String.Format("{0:D}", '<%# Bind("CReviewDate") %>')
and
Text= String.Format("{0:D}", <%# Bind("CReviewDate") %>)
[Code]....
In all cases I get a green wavy line under the equation and the tip help says "Validation (ASP.Net): If this attribute value is enclosed in quotation marks, the quotation marks must match. String.Format("{0:D}", DateTime.Now) is the syntax that I have been told should work.
my form need to show the current date when click on button. the code inside the button is TextBox1.text = System.DateTime.Now.After clicking, the textbox show "9/29/2009 4:32:10 PM" may i know is it possible for me to show only the date and also to change the format to dd/mm/yyyy?

I have a datagridview named "DG" bound to a datatable. The grid has one column that requires me to determine its value, so the grid has the virtual mode property set to true.When i try to add using the dg.rows.add, i get a message saying 'operation not valid while in virtual mode'.If i set the virtual mode to false and execute the dg.rows.add line i get."Rows cannot be programatically added to the datagrid's rows collection when the control is databound"Ok....i cannot use rows.add when in virtual mode,.....and i cannot use rows.add when i am in data-bound mode.So then next thing i try is ctype(dg.datasource,datatable).rows.add , This gets the row into both the underlying table as well as the into a new row located at the bottom of the grid.
I try this: dg.sort(dg.columns("Row"),ascending) and get this "Operation is not supported when VirtualMode is set to true." i try seting virtual mode to false and get this: "Data-bound DataGridView control can only be sorted on data-bound columns."The column "Row" IS a column in the underlying table.If i click on the column header it sorts correctly.All i want to do is add arow and have it be located in the correct place in the sort order.
can anyone give me a pointer as to how do i show all the columns in a combo box in visual basic 2008.[code]

View 3 RepliesMy DataGridView is not sorting my date column correclty and it doesn't seem to be sorting it by String either. The column is bound to a date property, all is done using the designer.The set which I'm viewing it on is 424 entries long, there should be two entries for each date and they should be next to each other (regardless if sorting by date or string)The last few dozen entries are sorted correctly but the initial entries are not.Initially every second entry at the start is correct. Here is an extract if some of the sorting it does.(The beginning of the sorted grid is on the left, and the end of grid is on the right)

Situation Overview I'm using Ext.NET GridPanel to display a list of projects which has tasks (i call it Sprints) inside it assigned to some user and a status. So I get this kind of relation:
SprintOwner -> UserID

In my GridPanel I display my sprints grouped by projects and I use the relationships to show their names instead of their IDs (SprintStatusName and UserName). It's in portuguese but I find it useful to show:
