I need to find a way to take a normalized table, and display it in a crosstab format for users to enter and edit data in a data grid. For Example:
Table Structure.
MONTH CLIENT AMOUNT PRICE
01/01/2007 FRANK 45 $25.00
[code]......
What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?
this is my code to format column style at datagrid:
Private Sub frmCustomer_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sql As String = "select cust_id,cust_name From inv_t_Customers order by cust_id"
[code].....
How do you load a variable directly from a db record entry Thought it would be something like this
Code:
Dim TempUserName as string
Me.TblUsersBindingSource.Movefirst
TempUserName= Me.TblUsersBindingSource.List("UserName").Tostring()
Apparently not....
the combo box style 1 has both the drop down option but also a manual entry option. I need to know how to code it so that when you manually enter data, it takes that data and places it in a text message "The shipping charges for "data" is $15" displaying in a text box. Shouldn't be hard but have developed a mind block.
View 4 RepliesIm new to VB programing and Im using VB 2008 Express. I have set up two forms (Main and Edit) and I have a datagrid set up on each form. I can make changes to he DB on the edit form, close it, and the main form is updated with the new info. All is well except that Im also trying to enter data directly into the cells on the DataGrid on the main form and I cant. I can select the cell and it highlights it but it wont accept any characters.
View 1 RepliesI'm presently creating an application which uses Access2007 as the database. No problem there. But Since most use Excel for data-entry, i've created two tables in access linked to excel source file. Any change in excel will reflect in Access database and subsequently in my Application . Until now my application only reads the database and displays records in DataGridView. These records, i then export to excel along with other formatting for direct printing as a report as I have no idea how to make report. Now i want to add data-entry capability to my app using password-protection user-access. So i can directly add new record to source file. Also need to know if There's any way of eliminating Access from the picture entirely....

View 3 RepliesI got stuck with my program and I can't figure it out by myself. I have a problem in getting the total summary of my crosstab. Here's my sample report.As you can see on my report, you will notice that I set the Section Footer (it is not visible here) to Suppress (No Drill Down). Here's my formula
if {creditmemo_list.CreditReturn}="Yes" then
true
else
false
And it works fine. All I want is to get the value of total summary (Sum of @ii) of the crostab and subtract it to the value of #TotalBalance and the result would be the @GrandTotal.
The formula of my @GrandTotal should be #TotalBalance} - {(Sum of @ii)} <-Actual value of this object?+.`
Is there anyway to import a crosstab query from Access 2007 to VB 2005?If not, can I create a crosstab query within VB 2005 from the raw database tables
View 3 RepliesI am working in VB.NET08 I was created Crosstab for table called 'Crosstabtemp' as given below:
Crosstabtemp= CrossTab(tblB, "PersonID", "ContactMedium", "ContactNumber", "Personal_")
I was declared Crosstabtemp as a Datatable in my above code.
I want to use the Crosstabtemp in my further sql query.
I need to join few Db tables with this Crosstabtemp??
I have a problem with my datagrid(I am noob sorry if its simple). The datagrid is binded to a data table. What i want do is when a product is added or an existing one changed then make that one the selected row in the datagrid. The SelectionMode of the DataGrid is set for the whole row.
Here is the code that i am currently using,[code...]
Now as you can see from my code i don't understand how the index can be wrong as the datagrid is binded to a datatable and the indexes would be the same, and i have the current row in the datatable and look for the index in the datatable and stored it as a Integer!
I have taken up a task where end user should be able to enter information via vb interface into microsoft Access database. This then will be displayed onto the Datagrid via VB interface. The program needs to be setup in a way that first entry by end user will flash upon 3 hours.
Example:
VB Interface
=========
Basket Number | Number of Trays | Run Type | Time In
1 | 1 | CNC | 15:00:00
[code]....
Values defined within database shows in this datagrid.The Datagrid works fine and I can insert values into the database fine as well however, I am not sure how to setup a timer so that when 3 hours are up the first entry into the database(shown on datagrid) starts flashing.This is needed so that the end user gets an alert when the time is up so that he can take the trays out of the oven.
In Summary: Can we really setup a timmer so that a value in the datagrid will flash at a particular time.Below is the image of an application. Here you can see the data on the datagrid however I want it to flash after 3 hours. So the first entry will flash after 3 hours following the 2nd entry.

I am saving some operational log information into a XML file. At any time the user can bring up a datatable to display the information. I don't want them to see the 'HOURLY' log. I can't seem to filter this out. Also I need to populate a list box with all the unique events for filtering.
Example XML:
Code:
<?xml version="1.0" standalone="yes"?>
<DocumentElement>
<LOG_x0020_Table>
[code]....
how do I call the events for a datagrid? I want to update, add, and delete records to a bound datagridview. Is there a simple way to accomplish this? Most of the Database connections are handled but how is the editing handled?

I have a datagrid that I am populating from an Access 2000 query in Visual Basic 2008.
This code works fine:
With dgvCollections
.Columns(0).Visible = False
.Columns(1).Width = 235
.Columns(2).Width = 230
.Columns(3).Width = 220
.Columns(4).Width = 70
.Columns(4).HeaderText = "Loan"
End With
The query works fine, except that I want to change the alignment for one of the columns. I tried to add this line before the "End With":
.Columns(4).DefaultCellStyle.Alignment.MiddleCenter()
Which causes the error:
"Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
And this error:
"Expression is not a method."

My text file is something like what you see below, and I want to populate the datagrid. Once I populate the datagrid, I'll use that kind of like an excel spreadsheet in the sense that I'll dip in and grab values based on row and column index to display to the user. I will also (on a different form maybe) display the same datagrid to the users so they can sort by column at their choosing.[code]The error I am getting is: Value of type 'Integer' cannot be converted to 'System.Windows.Forms.DataGridViewCell'.
View 1 Repliesi am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.
