Forms :: Update Data In A Text Box On Form 1 From A Textbox On Another Form?
May 15, 2011
I was using 2 forms, the first one has general data capture and the second one is a calendar form. On Form1 I have mulitple windows controls. A Textb ox and beside a Calendar button. When I click on a Calendar Command button, it should open calendar form and once the user selects the date, the date should be placed in the text box on the form1. Identical to this on Form1 I need multiple textboxes that needs date to be captured.I cannot use a global variable for this as I need to validate mulitple text boxes. To explain this, I have a Transaction Date and Date Received. I need to validate whether Transaction date is prior Date Received or not? I dont want to use several global variables b'coz I might need multiple validations as above. Please help me on this.

I have a Main Module that loads a form. I want to update text on a Label, my code is:
Public mFormSplash As Form = New FormSplash
Sub Main
With mFormSplash[code]....
The code loads the form OK but does not update the Label's text (LabelStatus)I am getting an error Error:
'LabelStatus' is not a member of 'System.Windows.Forms.Form'.
This worked ok on a previous project and I can't work out what is different.

I am making a booking system. I am using same form for insertion and updation. How can I update by taking the values from the textboxes. For example if the user enters value for just 2 out of 8 fields then How can i update just 2 fields without affecting the rest of the record. I mean to say that if I use a single update query using all the fields then if some textbox is left empty then it will replace the database field value by null or something else.

How can I update and get values in a Windows Forms application while moving one form to other form (like cookies)?
I need to update the values to some variable and again I am going to refer stored values and need to do some calculations.
I have used cookies in ASP.NET but I am not able to find out the same concept in .NET Windows Forms (C#).
How can these issues be resolves?

I have a date selector on mdi parent that updates a property when date is changed. When I open a child form, it grabs the property just fine. However if I change the date again after the child is open the date does not change on the child unless I close and reopen the form as expected. What would be the best way to automatically update all open child forms when the date is changed on the parent at anytime? running a timer to parse the date property is impractical.

But... when I take look at the data (or close and reopen the forms) the data in the database (SQL server) have not changed! What happens!

In my application, I have a data bound form using a binding control (built by the wizard). The application has one primary data screen plus a few more on tabcontrol subscreens.Picture for example that the tabcontrol has two tabs, tab1 and tab2.When the form is displayed, tab1 is visible.Now picture the form or window split in half the top part of the form has a few textbox controls bound to the data and there are a few textbox controls in the lower half of the screen on tab1 of tabcontrol1.There are a few textbox controls on tab2 as well.When the form displays, I can access any of the .text properties of any of the textbox's that I can see on the form and in tab1 of the tabcontrol.BEFORE tab2 is chosen or even, I need to get some of the data from the .text property on a textbox control that is on tab2.I have tried to get the data but as far as VB is concerned, it does not appear to be there UNTIL tab2 is displayed.
To prove this, I put a command button on the form and it simply does this: MSGBOX (mytext box33. text)mytextbox33 is a databound control on tab2 of the tabcontrol1.tab2 is not in focus and apparently, neither is the data.how can I read the .text property of a textbox that is on a form but the form (or tab) is not in focus?

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I am having trouble getting the Student Name entered in the Student Name Form to change the Text titles of the GroupBox's on the Main Form and Schedule Form. I understand the logic of what needs to be done to some extent, but I am having trouble coming up with the correct coding.
Below is a snippet of the Student Name Form code that I tried most recently just to see if I could get any change to happen to the other 2 Forms when the Accept Name button was clicked. As of yet, I cannot get a change to happen at all in the groupboxes of the other Forms.[code...]

I have a simple vb.net app and I'm trying to update a one row Access table with data from some textboxes. This is a learning exercise for me as I am coming back from not programming for almost 10 years, and know there are lots of other ways to manage this data, but I'm just trying to understand different aspects of ADO.net a little better.
The ERROR I'm trapping is:
"Syntax error in UPDATE Statement"
Any thought's as to what is going on? (See CODE and stuff below)
Here's the Scheme printed from ACCESS showing the exact spelling of the database table and column names:
Table: MaxTime Name Type Size
ID Long Integer 4

I'm doing an application for a school to help them keep track of student attendance and because I'm rather new to VB 2008 .NET I'm sure I'm missing something simple.see the screen shot and attached sample application showing the problem I am having.
The screen shot shows 3 open forms. I'm not able to get the value from the 3rd open form into the Student ID textbox of the 2nd form even though my messagebox shows a value is really in there.The attached application has 3 forms similar to the production application I'm writing which also includes 3 forms. Could you look at the application and tell me what we are missing to get the textbox data in the 2nd form to show up?

I have a project in which i have a form in which there is add button to add pages. In form load the last entered page populates all the fields. Now thing is if user edits the values in controls it has to update the db with those fields and if the page doesn't exist in db it has to insert.
Here is my code
Private Sub inserting()
Dim cn As New OleDb.OleDbConnection
'Dim selectquery As String
cn.ConnectionString = ""
Dim cmd As New OleDb.OleDbCommand
[Code] .....
I initialized a global variable x and set its value to 0 in page load and in add button click to 1. Depending on x value it either inserts or updates the db in form closing and add button click. Now whats happening is If the user clicks on add button the page increments but if user doen;t enter any values and tries to close the empty form, value of x =1 and it tries to insert but as there are blank fields cmd.executenonquery throws an error.
"The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data."
What should I do so that it doesn't give an error. I am using access db.I even checked in db Except for primary key(pageno) all other fields have "allow zero length" as YES & "required" to NO.

All I want is to update the selected row data in form1 to another form2
Form1 Objects
Form1 = MainAppForm
DataGridView = DGVMain <= binded
Button = btnUpdate
Form2 Objects
Form2 = frmUpdate
Button = btnSubmit
15 textBoxes = you can see its name in the code below and all of them are data binded
MainAppForm Code
Pass the selectedrow data to form2 (frmUpdate)
Private Sub btnUpdateDouble_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
If DGVMain.SelectedRows.Count = 1 Then
Try
frmUpdate.ItemIDTextBox.Text = DGVMain.CurrentRow.Cells(0).Value.ToString()
frmUpdate.PartTypeTextBox.Text = DGVMain.CurrentRow.Cells(1).Value.ToString()
frmUpdate.PartNameValueTextBox.Text = DGVMain.CurrentRow.Cells(2).Value.ToString()
frmUpdate.PackageTypeTextBox.Text = DGVMain.CurrentRow.Cells(3).Value.ToString()
frmUpdate.QuantityTextBox.Text = DGVMain.CurrentRow.Cells(4).Value.ToString()
frmUpdate.UnitTextBox.Text = DGVMain.CurrentRow.Cells(5).Value.ToString()
frmUpdate.DescriptionTextBox.Text = DGVMain.CurrentRow.Cells(6).Value.ToString()
frmUpdate.LocationTextBox.Text = DGVMain.CurrentRow.Cells(7).Value.ToString()
frmUpdate.ProjectBoardTextBox.Text = DGVMain.CurrentRow.Cells(8).Value.ToString()
frmUpdate.CommentsTextBox.Text = DGVMain.CurrentRow.Cells(9).Value.ToString()
frmUpdate.OrderCodeTextBox.Text = DGVMain.CurrentRow.Cells(10).Value.ToString()
frmUpdate.CurrencyTextBox.Text = DGVMain.CurrentRow.Cells(11).Value.ToString()
frmUpdate.UnitPriceTextBox.Text = DGVMain.CurrentRow.Cells(12).Value.ToString()
frmUpdate.SupplierTextBox.Text = DGVMain.CurrentRow.Cells(13).Value.ToString()
frmUpdate.ManufacturerTextBox.Text = DGVMain.CurrentRow.Cells(14).Value.ToString()
frmUpdate.Show()
Catch ex As Exception
System.Windows.Forms.MessageBox.Show(ex.Message)
End Try
ElseIf DGVMain.SelectedRows.Count = 0 Then
MsgBox("Please select one item to update!", MsgBoxStyle.Information, "Update")
Else
MsgBox("Updating multiple Items is not allowed!", MsgBoxStyle.Information, "Update")
End If
End Sub
Form2 Code
I want to update the data by this code, but it refresh only the data in Form1
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Me.Validate()
Me.SparePartsBindingSource.EndEdit()
Me.SparePartsTableAdapter.Update(Me.InventoryDBDataSet.SpareParts)
'Refresh
MainAppForm.SparePartsTableAdapter.Fill(MainAppForm.InventoryDBDataSet.SpareParts)
End Sub
No problem in updating the data if I put the code below in Form2 load event
Me.SparePartsTableAdapter.Fill(InventoryDBDataSet.SpareParts)
but the problem is, it will refresh all the data in the Form2, and my code in Form1 becomes useless.
Thanks in advance!

I am converting some VB6 code which passed an unknown form object to a class, which then used the passed form object to reference the calling form and direct the data from the class as follows:
The Called Class in the class clsGetRecord
Public Function Execute(ByRef FRMForm as form) as booleanFRMForm.List1.Additem(SomeData)....Execute = SomeBool End Function
The clsGetRecord is used by many different forms which receive data all have objects called List1 as: The Calling Form for the form
frmThisFormPrivate function() as booleanDim objRecord as new clsGetRecordbRet = objRecord.Execute(frmThisForm)
The passed form object which will receive dataEnd function. Is there any simple way to do this since the calling form object is unknown at design time?
