On one form (form1) i have a simple textbox. On the other form (form2) i have 1 combobox and 1 textbox. The combobox and textbox are binded together to a datatable.
What i wan't is that when form2 loads firstly it shows the data from the textbox on form1. And when i select another value wit the combobox it shows the new data from the textbox on form1 to form2.
My problem is when form2 loads firstly no data is shown in my textbox. Why not???
How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow() Dim OrderWindow As Orders = New Orders OrderWindow.ShowDialog() End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.

I have problems with a form and load event.My form manage items that can be added, deleted or modified. In load code, I initialize all vars to cero. This is OK to be ready to add items.
My problem is with modify and delete. To carry this, I must load vars from a source. So, in my foreing code I have this:

My problem is that when showdialog is called, all data which were loaded from duplicar funct is put again to cero. How can I avoid this and load correct data into the form.
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.
i have 2 form. form 1 have combobox and second form textbox...how to load data form textbox into combobox..if i type hitachi in text box, automatictly "hitachi" will save in dropdownlist combobox..
Is there a way to load the data for my form during the splash screen and simply show the form when the user clicks on the button? I'm using a thread which fills my DataAdapter using Form.DataAdapter.Fill(Form.Dataset.Table), but when I open the form the data isn't shown (I removed the line from my form_load event to prevent a double load). Is there anyway to tell the form that the DataAdapter has been filled already and to look at the information there instead of loading the data everytime the form loads?
My problem is that the form takes a while to load due to the amount of data it is looking for. If I could already have the data ready and then display the form when the user clicks a button it'd be perfect. I apologize if I'm missing something, this is my first time diving into VB.Net with VS2010 after using Access VBA for awhile.
i add a rectangle and label to datagridview...my problem is that when i load the form the rectangle only shows on the last add data..how can i make all the data display in rectangle not only the last add data.[code]
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
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
When the form loads I want to fill the combobox with the data present in the database. So I did the below
Private Sub BindCombo() con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsF1pracF1pracBank_Account.mdb") con.Open() cmd = New OleDbCommand("Select * from BankAccount", con) [Code] .....
Doing this code the data is added up in the combobox dropdown list. But when I am selecting a data from the combobox dropdown list,the all the corresponding data of the other combobox also get filled automatically. I don't want to let the other combobox filled with their data automatically....

I have searched the web and this site for an answer but have not been able to solve this problem.I am not able to place a flashing cursor in a specified cell of a data bound DataGridView on Form_Load.My test project consists of a single Visual Basic 2008 form with a database created in Microsoft SQL Express 2005 using the Add New Data Source in the Data Sources window.The database has one table consisting of 2 columns.Column 1 being the primary key with Identity Specification set to On.The second column is a VarChar50.The DataGridView was placed on the form by dragging it from the Data Sources window thereby creating the Binding Navigator and the Private_Sub Form_Load code.I have added the code that should put the cursor where I want it.[code]
I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.
i am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Text = "Line " & LineNumber & " Test Form"
I want to load a child form which is a login form by default when the parent form is loaded.Right now when I click new file on the toolbar of the parent form, then only the login form is loaded but i want it be loaded by default without clicking anything.
I fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.
I have a small program which draws some lines with a method called: Drawlines But Now I want to call this method in the load form routine. So if the form is loaded the lines should be drawn in the picturebox. But is this possible or should the form first be loaded completely before you can call methods in that same form?
In MDIParent, in my formload in MDIParent, one form is load. And i want the form when i click a button, there is another form will be loaded INSIDE the MDIParent?
I want one form frmFrontEnd to be the base of my application, so when i press F5 it is the first to 'open/be seen' and then from here using previous i want other forms to open. How can i set frmFrontEnd in the form load event to be the parent form? If you're not living on the edge, you're taking up too much room
I open a form using .showdialog and load some info onto it. I have code that runs on the MyBase.Load event. Basically, I have a Try, Catch, End Try block and if the Catch executes in preparing my information, I want the form to stop loading i.e. give a message and not show at all.
